Piston mechanism of interaction of non-linear geomechanical and physicochemical gas exchange and mass transfer processes in coal-bearing rocks

The article focuses on a theoretical and experimental framework for the quantification of interaction between nonlinear geomechnical and physicochemical processes in high-stress coal-bearing rock mass during mining under high seismic risk due to large-scale blasting and earthquakes, as well as because of structural and temperature effects. The tests were aimed to examine and study comprehensively the piston mechanism of gas exchange and mass transfer processes, revealed recently at the Institute of Mining, SB RAS, as well as to explain the fact that the earthquake-induced low-velocity (quasi-meter range) pendulum waves (velocity to 1 ​m/s and frequency of 0.5–5 ​Hz) could stimulate an increase in the gas content in coal mines. In order to perform laboratory investigation at the Institute of Mining SB RAS, special-purpose stand for analyzing gas exchange and mass transfer processes in coal-bearing geomaterials under various thermodynamic conditions (P, V, T) and gas composition was constructed in cooperation with the Institute of Semiconductors Physics SB RAS. Matching of air flow rate with compression pressures allowed to obtain relations showing that air flow rate increases at the uncertain time interval under the increasing of the compression pressure. The same measurements was carried out with another gases such as Hydrogen H2, Helium He, methane CH4, carbon dioxide CO2 and carbon oxide CO. The laboratory tests aimed to detailed investigation of the previously revealed “piston mechanism” of gas exchange and mass transfer processes in the coal specimens and their quantitative description in terms of theory of the pendulum waves were carried in the first time. Consequently, there are some arguments for the testing of the opportunity of quantitative description of the “piston mechanism” related to gas exchange and mass transfer processes in the scale of coal mines. It is relevant when pendulum waves induced by powerful earthquakes and technical blasting reaches the mine.

The Influence of Axial Compressive Stress and Internal Pressure on a Pipeline Network: A Review

Due to their exceptional structural integrity, steel pipelines are the main component for oil and gas transmission. However, these pipelines are often affected by corrosion, despite corrosion protection, because of harsh working conditions. In addition to corrosion defects, pipelines are often subjected to multiple external loads. The combination of corrosion defects and external loads can significantly reduce the failure pressure, resulting in various failure behaviors. This reduction in failure pressure is especially critical in pipe bends as they are the weakest link in a pipeline. This paper presents an overview of the failure behavior of corroded steel pipe components subjected to internal pressure and axial compressive stress.

Loading diagrams and parameters of the model of elastic-pseudoplastic deformation of black shale rocks of the Bazhenov formation

The results of the analysis of experimental data on pseudotriaxial loading of full-size samples of black shale rocks of the Bazhenov Formation are presented. The experiments were carried out under conditions of uniaxial loading and at lateral compression pressures of 20 and 40 MPa. It is shown that in the considered load range, the deformation of the rock beyond the elastic limit proceeds in different modes: dilatancy and compaction. Despite the low porosity of the rock, the transition from dilatation to compaction occurs at a pressure not exceeding 34 MPa. Based on the analysis of the obtained data, the stages of deformation in the loading diagrams are distinguished and the parameters of the mathematical model with a combined limiting surface are determined, which describes the deformation process in dilatancy and compaction modes.

Evaluation of functional and radiological outcome of transverse cancellous lag screw fixation technique in pauwels type 3 fracture neck of femur

The study was conducted to evaluate the outcomes of transverse cancellous lag screw (TCLS) fixation in pauwels type 3 fracture neck of femur (NOF). 29 patients with pauwels type 3 fracture neck of femur were operated with transverse cancellous lag screws. Functional outcome was evaluated using Harris hip score while RUSH score was used to evaluate radiological outcome. The follow up period was 6 months. Quantitative variables were compared using unpaired t- test/Mann- Whitney test. Qualitative variables were compared using Chi-Square test /Fisher’s exact test. Pearson correlation coefficient/Spearman rank correlation coefficient was used to find out the correlation between quantitative variables. A p value of <0.05 was considered statistically significant. Mean Harris hip score was 84.86 with excellent outcomes in 44.82% of patients. Mean RUSH score was 26.55 at the end of 6 month follow up. The mean time to union was 4 months and the union rate was 93.10%. Over all TCLS fixation technique had good results in our study. This construction not only improves the compression pressure across the fracture site, also offer a multi-plane structure to lock the fracture ends. The addition of the transverse lag screw (inserted perpendicularly to the fracture line) allows optimum control of shear forces in the fracture ends. The transverse screw also provides rigid cortical support by transferring the bending moments from the femoral head and neck to the enhanced posterior lateral cortical support, which harmonized the function of the calcar femorale.

Microencapsulation of agarwood (Aquilaria crassna) essential oil by spray drying

Agarwood essential oil is the essential oil extracted from the heartwood of agarwood trees (Aquilaria sp.) after inoculation or natural infection of one of several fungal species. The essential oil is proved to carry antioxidant, antimicrobial and anti-stress activities. Microencapsulation of essential oil included emulsification of oil into maltodextrin solution and spray drying of emulsion at different levels of inlet temperature and compressed air pressure. Microencapsulation process was qualified based on following parameters including process’s microencapsulation yield, moisture content of powder, powder particle size, encapsulated oil’s composition, oil recovery and drying yield. Microencapsulation yield was affected by inlet temperature whereas drying yield changed as air pressure varied from 1.5 to 2.5 kgf/cm2. Other parameters were impacted by both variables. Besides, oil composition changed at an acceptable degree after microencapsulation process, in which there were an increase in percentage and the presence of some components but the main components still remained in the encapsulated oil. Finally, the drying air temperature of 150 °C and air pressure of 2.5 kgf/cm2 were the best parameters to obtain both microencapsulation yield of 89.12% and drying yield of 79.00%.

Orenburg Radial-Concentric Structure at Great Depth: Experimental Modeling under Fluid Dynamic Loads and Comparative Analysis of Sandstone Samples from Oil Fields in Western Siberia

The study of the deep structure of the Orenburg radial-concentric structure in the basement of the Russian Platform based on seismotectonic and geomorphological data has been carried out. Interpretation of temporal regional seismic profiles crossing the structure was performed, identifying the main deep faults and measuring their dip angles. It was revealed that the radial-concentric structure is a large flower structure. Its structure involves the main multidirectional deep faults dipping at angles of \(\perp \)60°–85° and limiting horst or reverse fault zones in the basement. The hierarchy of faults structure has been established. Oil and gas fields are confined to the main deep dislocations of the Orenburg structure and represent flower structures of minor sizes. An experimental modeling of the formation of “flower” structures was performed based on the analysis of the results of studies using data from the acoustic emission activity of rocks and under the action of fluid dynamic loads performed at the “UIK-AE” unit (Institute of Geophysics, Ural Branch of RAS, Russia) on sandstone core samples from reservoir rocks of oil fields in Western Siberia. The developed model showed that the formation of flower structures can occur without horizontal shear due to lateral compression and deep pressure. With the help of the seismo-acoustic emission method, characteristic noise was recorded during the formation of cracks in core samples, sound attenuation before splitting, and then its sharp explosive increase from a break in the continuity of the rock. Analysis of the core of wells drilled within the Orenburg radial-concentric structure revealed signs of hydrothermal fluid discharge in the sedimentary cover rocks, such as wavy (or flat) layering, bizarre textures and intervals of breccias, shell-shaped inclusions, stillotite seams, fluid textures. It is concluded that the genesis of the Orenburg radial-concentric structure is associated with the impact of deep heat flows, fluids, high pressure and has a commonality with the explosive ring structures of shields and platforms.

A molecular dynamics study of water confined in between two graphene sheets under compression

Several studies have demonstrated interest in creating surfaces with improved water interaction and adaptive properties because the behavior of water confined at the nanoscale plays a significant role in the synthesis of materials for technological applications. Remarkably, confinement at the nanoscale significantly modifies the characteristics of water. We determine the phase diagram of water contained by graphene stack sheets in slab form, at T = 300 K, and for a constant pressure using molecular dynamics simulations. We discover that, as shown in the simulation, water can exist in both the liquid and vapor phases depending on the confining geometry and compressibility ratio. We also pay attention to how stable the interacting liquid is in relation to the pressure of compression that is perpendicular to the graphene sheets. To build this system and analyze its surface interface properties, we also used analytical and electronic scale modeling approaches. The impact of nanoconfinement on internal pressure may be seen in water, and this can be used to create interfacial materials for the creation of environmentally friendly solar cell materials. Our research highlights the intricate, seemingly random behavior of nanoconfined water—behavior that is difficult for graphene to understand. The results obtained offer crucial direction for system design and configuration of materials at the graphene/water interface that can be utilized as a benchmark for other future designs.

Compressible, reliable, and flexible pressure sensor based on carbonized melamine foam capped by Ti3C2Tx MXene for versatile applications

Flexible pressure sensors with excellent sensing properties have caused widespread concern due to their various potential applications in personalized healthcare monitoring, disease diagnosis and human-machine interaction. However, the challenge remains to simultaneously achieve high sensitivity and low fabrication cost. Herein, a compressible, reliable and flexible piezoresistive pressure sensor of Ti3C2Tx MXene/carbonized melamine foam (MXene@CMF) was fabricated by coating two-dimensional (2D) Ti3C2Tx MXene on the skeleton of carbonized melamine foam. Owing to the synergic effect of carbonized melamine foam and Ti3C2Tx MXene, the as-prepared MXene@CMF shows excellent performance in terms of high sensitivity (similar to 0.166 kPa−1), fast response time (similar to 120 ms), subtle pressure detection limit of 9.6 Pa, and excellent cyclic stability. Benefiting from these excellent sensing capabilities, the applications of the sensor for artery pulse detection and bending joint monitoring are demonstrated. Moreover, with the assistance of the convolutional neural network, the proposed sensor can realize the exquisite identification of letter strokes with an average recognition accuracy of 96.3%. Based on the merit of high sensing performance and versatile application prospects, our proposed sensor may have great potential in medical and healthcare, human motion detection, handwriting verification, and anticounterfeiting applications.

Strength Characteristics of a Heat-Resistant Metal-Matrix Composite Inconel 625–5%NiTi–TiB2 Alloy Fabricated by Direct Laser Deposition under Shock-Wave Loading

The Hugoniot elastic limit and spall strength were measured for a heat-resistant metal-matrix composite Inconel 625–5%NiTi–TiB2 alloy additive manufactured (AM) by direct laser deposition. The strength characteristics of the alloy were obtained from the analysis of the complete wave profiles recorded with a VISAR laser Doppler velocimeter during shock-wave loading of the samples. The samples were loaded using a PP50 pneumatic gun or ad hoc explosive devices along and across the material deposition direction in order to determine the strength anisotropy of the AM alloy under study. The maximum shock compression pressure was ~7 GPa, and the strain rate under tension before spalling varied in the range of 105–106 s–1. Kinetic dependencies of elastic/plastic transition and critical fracture stresses vs. loading conditions were plotted. It was shown that the Hugoniot elastic limit of the alloy under study decreases as the shock wave travels into the sample, while the spall strength increases as the material’s strain rate increases at the moment of spall fracture. A comparison of the strength characteristics of the Inconel 625–NiTi–TiB2 composite alloy with the original Inconel 625 alloy has shown that an addition of 5% of powder based on NiTi-TiB2 leads to a decrease in its elastic limit and critical fracture stresses upon spalling by more than 10%. The alloy under study demonstrates anisotropy of strength properties relative to the material deposition direction.

Experimental investigation on bond behavior of CFRP-concrete interface with end anchorage in hygrothermal environments

Externally bonded reinforcement (EBR) of reinforced concrete (RC) structures with fiber reinforced polymer (FRP) is unable to meet the requirements of the engineering. Because premature debonding failure limits the usage scenario of the EBR method, which cannot fully utilize the high tensile performance of FRP. More and more studies focus on the improvement of the EBR method by extra anchors on the FRP-concrete interface to improve its ultimate strength. Considering the influence of environmental conditions on the FRP-concrete interface with anchorage, the application of extra anchorage under hygrothermal environments has to be investigated. The paper optimizes the existing end mechanical anchorage to avoid damage to carbon fiber reinforced polymer (CFRP) and concrete substrate. The compressive pressure exerted on the CFRP laminate can be controlled by adjusting the torque on the end anchorage. A series of end-anchoted double-lag shear tests under different hygrothermal conditions were carried out for invesitgating the bond behavior of CFRP-concrete interface. The test results showed that the load increment of the ultimate strength of the CFRP-concrete interface decreased with the increase in temperature and relative humidity. Correspondingly, friction surfaces due to the compression provided by end anchorage changed from concrete-concrete interface to the concrete-adhesive or adhesive-CFRP interfaces. The relationship between friction coefficient and temperature and relative humidity was built. The shear stress and slip distribution curves were calculated from the strain distribution functions fitted from the strain data measured by DIC. Fracture energy for the CFRP-concrete bond was estimated, and the bond-slip relationship for the hygrothermal conditions was constructed.

Mechanical properties of electroporcelain as a function of temperature and compacting pressure

High voltage insulators are an integral part of the electrical infrastructure worldwide and are prepared by compacting. For this reason, it is essential to optimize the production process, especially from the economical and environmental points of view. This study aims to find the influence of the compaction pressure and firing temperature on the microstructure, mechanical properties, and matrix density of electroporcelain samples. The C-130 type electroporcelain was prepared with compaction pressures ranging from 70 MPa to 110 MPa and subsequently fired at 1100 °C, 1200 °C, 1300 °C, and 1400 °C. The results show that the higher compression pressure does not lead to a significant improvement in the studied mechanical properties (flexural strength, Young's modulus, and Vickers hardness). On the other hand, the firing temperature positively affects the mechanical properties of the samples. Also, with an increase in the firing temperature the matrix density is decreasing due to the formation of closed porosity above 1200 °C. The mechanical properties reached their maximum values after firing at 1300 °C.

파수-주파수 변환을 이용한 선체 벽면 압력으로부터 선박 추진기 압축성 압력 추출

Underwater radiated noise (URN) is a compressible pressure component that propagates in the far-field from sources. Therefore, compressible pressure separation is required as a first step in developing a far-field URN monitoring technique based on hull surface pressure. In this study, a numerical method of decomposing surface total pressure induced by an underwater propeller into compressible and incompressible pressure was proposed using wavenumber-frequency transformation (WFT). First, a compressible multiphase Delayed Detached Eddy Simulation (DDES) of the hydrodynamic flow field was computed. Acoustic pressure caused by cavitation from the underwater propeller was predicted using the Ffowcs Williams–Hawkings (FW–H) integral equation and compared with the measured data to validate the numerical simulation. Finally, the compressible pressure was extracted from the total surface pressure on the stern part by using the WFT decomposition technique. In the high-frequency range, the compressible pressure appeared to be relatively high compared to the incompressible pressure in this study.

Postbuckling behavior of functionally graded porous toroidal shell segments with surrounding elastic media subjected to combined mechanical loads

AbstractBuckling and postbuckling behavior of toroidal shell segment (TSS) made of functionally graded porous material (FGPM), exposed to a thermal environment, surrounded by an elastic medium and subjected to combined action of axial compression and lateral pressure are investigated in this paper. Material constituents are varied across the thickness according to power‐law functions, while porosities are distributed in the TSS in the form of cosine functions of thickness variable. Governing equations in terms of deflection and stress function are derived based on classical shell theory taking into account geometrical nonlinearity and interactive pressure from surrounding elastic media. Multi‐term analytical solutions are assumed for simply supported TSSs and Galerkin method is used to obtain nonlinear load–deflection relations from which buckling loads can be derived. Parametric studies are carried out to access the influences of material and geometry properties, porosity coefficient and distributions, preexisting loading conditions, thermal environments and surrounding elastic media on the buckling resistance and postbuckling load carrying capabilities of FGPM TSSs.

Effect of Surgical Release of Entrapped Peripheral Nerves in Sensorimotor Diabetic Neuropathy on Pain and Sensory Dysfunction—Study Protocol of a Prospective, Controlled Clinical Trial

Nerve entrapment has been hypothesized to contribute to the multicausal etiology of axonopathy in sensorimotor diabetic neuropathy. Targeted surgical decompression reduces external strain on the affected nerve and, therefore, may alleviate symptoms, including pain and sensory dysfunction. However, its therapeutic value in this cohort remains unclear. Quantifying the treatment effect of targeted lower extremity nerve decompression in patients with preexisting painful sensorimotor diabetic neuropathy and nerve entrapment on pain intensity, sensory function, motor function, and neural signal conduction. This prospective, controlled trial studies 40 patients suffering from bilateral therapy-refractory, painful (n = 20, visual analogue scale, VAS ≥ 5) or painless (n = 20, VAS = 0) sensorimotor diabetic neuropathy with clinical and/or radiologic signs of focal lower extremity nerve compression who underwent unilateral surgical nerve decompression of the common peroneal and the tibial nerve. Tissue biopsies will be analyzed to explore perineural tissue remodeling in correlation with intraoperatively measured nerve compression pressure. Effect size on symptoms including pain intensity, light touch threshold, static and moving two-point discrimination, target muscle force, and nerve conduction velocity will be quantified 3, 6, and 12 months postoperatively, and compared (1) to the preoperative values and (2) to the contralateral lower extremity that continues non-operative management. Targeted surgical release may alleviate mechanical strain on entrapped lower extremity nerves and thereby potentially improve pain and sensory dysfunction in a subset of patients suffering from diabetic neuropathy. This trial aims to shed light on these patients that potentially benefit from screening for lower extremity nerve entrapment, as typical symptoms of entrapment might be erroneously attributed to neuropathy only, thereby preventing adequate treatment.

Quasi-Isentropic Compression of Gaseous Helium and Deuterium in Spherical Structures at Terapascal Pressures

The results of four experiments on studying preliminarily statically compressed gaseous helium and deuterium during their subsequent compression in explosive spherical cascade structures providing quasi-isentropic gas compression are presented. For helium, the following parameters were achieved: in one experiment, the compression pressure is Pmean ≈ 4.9 TPa at a density ρmax ≈ 6.4 g/cm3 and the compression ratio is δ = ρ/ρ0 ≈ 320; in another experiment, Pmean ≈ 10.9 TPa, ρmax ≈ 10.3 g/cm3, and δ ≈ 470. For deuterium, these parameters are Pmean ≈ 3.4 TPa, ρmax ≈ 6.0 g/cm3, and δ ≈ 162 in one experiment and Pmean ≈ 13.3 TPa, ρmax ≈ 11.4 g/cm3, and δ ≈ 520 in another experiment. The gas density was determined by an X-ray method using the position of the boundaries of the steel shells compressing a gas. The experiments are simulated with a one-dimensional gasdynamic software package, in which the Kopyshev–Khrustalev equations of state are used for the gases under study. The pressures are determined using calculations, in which the dynamics of gas compression is satisfactorily simulated for the entire set of experiments.

Combined composites layup architecture and mechanical evaluation of type IV pressure vessels: A novel analytical approach

Strict requirements for cost and reliability of compressed gaseous pressure vessels as on-board hydrogen storage necessitates in-depth understanding on the mechanical responses of the composite structure. General numerical methodology to assess this involves a two-step setup: composite layup generation and mechanical property calculation, which becomes highly time and resource-consuming, particularly if multiple designs are scanned for optimization. This study presents a multi-functional analytical tool, combining both aforementioned steps in a single modeling framework. The model enables quick prediction of the strain/stress distribution in correlation with uncomplicated inputs describing the layup design, i.e. stacking sequence with desired winding angles. Additionally, the mechanical evaluation specially focuses on the dome region whose calculation has hardly been inspected analytically in the literature. The results are validated against a three-dimensional finite element calculation implemented in Ansys Workbench, showing qualitative and quantitative agreement. Overall, the study paves the way for composite tank design using analytical approaches, with easy implementation, minimum computational cost and great transparency.

Visualization of Swift Ion Tracks in Suspended Local Diamondized Few-Layer Graphene.

In the present study we investigated the nanostructuring processes in locally suspended few-layer graphene (FLG) films by irradiation with high energy ions (Xe, 26-167 MeV). For such an energy range, the main channel of energy transfer to FLG is local, short-term excitation of the electronic subsystem. The irradiation doses used in this study are 1 × 1011-5 × 1012 ion/cm2. The structural transformations in the films were identified by Raman spectroscopy and transmission electron microscopy. Two types of nanostructures formed in the FLG films as a result of irradiation were revealed. At low irradiation doses the nanostructures were formed preferably at a certain distance from the ion track and had the form of 15-35 nm "bunches". We assumed that the internal mechanical stress that arises due to the excited atoms ejection from the central track part creates conditions for the nanodiamond formation near the track periphery. Depending on the energy of the irradiating ions, the local restructuring of films at the periphery of the ion tracks can lead either to the formation of nanodiamonds (ND) or to the formation of AA' (or ABC) stacking. The compressive strain value and pressure at the periphery of the ion track were estimated as ~0.15-0.22% and ~0.8-1.2 GPa, respectively. The main novel results are the first visualization of ion tracks in graphene in the form of diamond or diamond-like rings, the determination of the main condition for the diamond formation (the absence of a substrate in combination with high ion energy), and estimates of the local strain at the track periphery. Generally, we have developed a novel material and have found how to control the film properties by introducing regions similar to quantum dots with the diamond interface in FLG films.

Taguchi Method Optimization of Water Absorption Behavior by Wheat Straw-Basalt Hybrid Brake Pad Composite

The application of biomass-derived composite material is in high demand worldwide in various commercial sectors, including automotive, due to its durable, cost-effective, and environment-friendly characteristics. However, one of the limiting factors of biomass-based composites is its higher water absorption capacity compared to commercial synthetic composites. Therefore, this study aimed to optimize the water absorption capacity of biomass-based, wheat straw fiber-basalt hybrid composite brake pad using the Taguchi method by considering the particle size and volume % of the composite compositions. The composite synthesized in this study carried two variations of particle sizes of basalt, wheat straw, steel, river sand, and graphite, as well as two-volume percentages of epoxy resin for optimization. All composites were molded using a compression molding process at compressive pressure of 6 MPa for 2 h curing in a forced convection oven at 100 °C. Water absorption capacity has been determined according to ASTM D570. The wheat straw fiber has been chemically treated with 5 wt.% of sodium hydroxide (NaOH) to remove the impurities, lignin, and hemicellulose and increase the surface area of the fiber, resulting in a larger area of contact between the fiber and the matrix. Elemental analysis, crystallinity, morphology, and mechanical strength of wheat straw fiber-based composites have been determined by XRD, SEM, and compression tests, respectively. The statistical method, analysis of variance (ANOVA), was implemented for Taguchi optimization of the composite compositions. The maximum compressive strength and minimum and maximum water absorption capacity of composites were obtained as 77 MPa, 3.55%, and 26.86%, respectively. From the optimum setting of the confirmation experiment, the optimal water absorption value of 5.718% has been obtained. The optimum particle size of the composite compositions was 1 mm basalt particle, 0.5 mm wheat straw fiber, 1 mm steel particle, 1 mm river sand, 0.5 mm graphite dust particle, and 30 vol% epoxy resin by Taguchi method. The parameter impact of Taguchi ranking on water absorption capacity presented the maximum improvement of water absorption, 10.47%, with river sand particle size.

Compressor Air Pressure and Brake Shield Distance to Braking Speed in Antilock Braking System Brakes

The development of automotive technology to date is very fast. In the city, it is almost rare to find conventional cars. Most are already using modern technology. The hallmark of modern cars is that they are not fully mechanical. Already combined with several electric and pneumatic tools. Until now the development in the field of chassis is endless. Its initial development began with the discovery of ABS (Anti Lock Brake System) brakes. Basically, ABS is followed by supporting components such as EBD, ESP, and so on.All of this is actually inseparable from the main function of braking. Namely so that the car can run well / smoothly, deceleration and stop as desired appropriately. The parts of the brakes that are most influential are the brake shoes and discs and the compressed air from the brakes. Also the most influential accuracy is the distance of the brake shroud. Therefore, in this study the aims of 1. To find the effect of pressure and brake shroud distance. 2. What is the minimum air pressure and brake shroud for the brakes to work properly (grip). This research uses experimental design method. The data is processed with the Minitab program. Data processing shows that: 1. The braking speed is influenced by the amount of compressed air pressure. Partially the distance of the brake shroud does not affect the braking speed. But the interaction of pressure and shroud distance has an effect on braking speed. 2. Air pressure that can be used as a fast ABS braking process is 3.75 – 4.25 (bar) with a shroud distance of 5 (mm) Keywords: Car Brake, Antilock Brake System, Brake Air Pressure, Brake shroud.

An Ultrasonic Study to Explore Interactions between Fertilizer and Aqueous Saline Salt Solutions

The acoustic (obtained thorough ultrasonic [NDT] characterization), thermodynamic, and volumetric parameters help to forecast and understand the behavior of intermolecular interactions, strength, or weakness as well as the ilk of the liquid mixture. In this paper, an attempt is carried out to understand the structural or molecular alterations of fertilizer in saline soil salts which results from several solute–solvent, solvent–solvent, and ion–solvent interactions present in the systems to find a way to control the problem of salinity of the soil. Because of the above facts, the ultrasonic velocity (U) and density (ρ) measurements studies on fertilizer name as ammonium sulfate having the number of concentrations varying from 0.02 to 0.2 mol kg−1 in water also in 0.5 mol kg−1 aqueous soil salt solution at different temperatures. The various acoustical, thermo-dynamical, and volumetric parameters that can be calculated are adiabatic compressibility (β), acoustic impedance (Z), intermolecular free length (Lf), specific heat ratio (γ), non-linear parameter (B/A), isothermal compressibility (kT), Pseudo-Grüneisen parameter (Γ), and internal pressure (πi). Hence, the present study exposes the structural sense of the experimental liquid mixture and results have been described in the light of intermolecular interaction existing in between the fertilizer–water–saline salt solutions.
