Molecular dynamics study of the formation of the nanocrystalline structure in nickel nanoparticles during rapid cooling from the melt

The formation of a nanocrystalline structure in nickel nanoparticles during their rapid cooling from the molten state was studied using the molecular dynamics method. The influence of the cooling rate in the range from 5∙1010 to 5∙1012 K/s and particle diameter from 1.5 to 11 nm on the features of the resulting structure, the amount of stored energy, and the temperature of the onset of crystallization were considered. At a rate above 1013 K/s, crystallization did not have time to occur in the model used; at a rate from 1012 K/s to 5∙1012 K/s, a nickel particle crystallized with the formation of a nanocrystalline structure. With a decrease in the cooling rate, a decrease in the density of defects and the number of grains in the final structure of particles was observed. It is also shown that the crystallization temperature during rapid cooling is inversely proportional to the particle diameter and increases with decreasing cooling rate. The melting of a nanocrystalline particle, due to the high content of grain boundaries and other defects, occurs at lower temperatures compared to a single-crystal particle.

Excellent energy storage performance of Mn-doped SrTiO3-BiFeO3 thin films by microstructure modulation

Dielectric thin film capacitors are expected to be a promising candidate for high-performance energy storage devices due to their high power density, fast charge/discharge speed, and excellent stability. Nevertheless, it remains a challenging endeavor to develop dielectrics with excellent energy storage density comparable to that of commercial batteries. In this work, lead-free 0.8SrTiO3-0.2BiFeO3 (0.8STO-0.2BFO) thin films with coexisting amorphous and nanocrystalline structure were prepared by a sol-gel method. The heat-treatment temperature was adjusted to form polar-nano regions, thereby modulate the breakdown strength and dielectric polarization, and increase the energy storage density. The electric potential, electric field, and current density of the films with different amorphous/crystalline volume fractions were evaluated by the finite element simulation to further verify that the proper crystallization can result in the improved polarization performance and increased breakdown strength of the films, which are beneficial to the enhancement of energy storage performance. Through structural tailoring, the 0.8STO-0.2BFO film annealed at 550 °C demonstrates the optimal energy storage properties with a giant discharge energy storage density of 65 J/cm3 and high efficiency of 75% at room temperature. Simultaneously, a broad temperature stability (20–160 °C), superb operating frequency stability (20 Hz-2 kHz), and excellent fatigue endurance (6.3 ×105) are observed without appreciable degradation of the energy storage performance. The excellent energy storage performance indicates a widespread potential of 0.8STO-0.2BFO films in pulse power applications, such as consumer electronics, microelectronics, and medical devices.

Interaction of Si Atom with the (001) Surface of TiN, AlN and TaN Compounds

Nowadays, the application of multicomponent coatings with multiphase nanocrystalline structure is the most promising direction in the search for wear-resistant protective coatings with a full set of necessary operational properties. Nanocrystalline multicomponent coatings based on the Ti-Al-Ta-Si-N system have a high hardness combined with thermal stability and oxidation resistance. Silicon atoms are weakly soluble in the TiN, Ti1−xAlxN, and TaN crystalline phases of the Ti-Al-Ta-Si-N system and interact preferentially with N atoms, forming the amorphous Si3N4 phase. In this context, it is important to first study the peculiarities of the interaction of Si atoms with the simplest structural units of the Ti-Al-Ta-Si-N system, such as TiN, AlN, and TaN compounds with the NaCl structure. This work is devoted to the study of the interaction of a Si atom with the (001) surface of AlN, TiN, and TaN compounds with the NaCl structure using ab initio calculations. This provides information for a deep understanding of the initial stages of the formation of different crystallites of the considered composite. It was established that the adsorption of silicon on the (001) surface of AlN, TiN, and TaN significantly increases the relaxation of the surface layers and leads to an increase in the corrugation observed on the clean surfaces. The largest corrugation is observed on the surface of the TaN compound. The most energetically favorable adsorption positions of Si atoms were found to be the position of Si above the N atom on the TiN and TaN surfaces and the quadruple coordinated position on the AlN surface. The valence electron density distribution and the crystal orbital Hamiltonian population were studied to identify the type of Si atom bonding with the (001) surface of AlN, TiN, and TaN compounds. It was found that silicon forms predominantly covalent bonds with the nearest metal and nitrogen atoms, except for the quadruple coordinated position on the surface of TiN and TaN, where there is a high degree of ionic bonding of silicon with surface atoms.

Preparation of the NiO/FeAl2O4 nanopowders and their application in CH4 thermocatalytic decomposition to produce high purity of hydrogen: Optimization of the synthesis parameters using Taguchi design of experiment

The present research is centralized on designing and optimizing the preparation conditions of the NiO(50)/FeAl2O4 catalyst in the thermocatalytic decomposition of CH4 (TDM). The mesoporous FeAl2O4 powders were synthesized by various methods, and the supported nickel catalysts were employed in the TDM. The results showed that the catalyst supported on FeAl2O4 synthesized by the modified co-precipitation (MCOP) method possessed the best efficiency, and CH4 conversion and H2 yield were 74 and 82% at 675 °C, respectively. Taguchi L9 statistical experimental design was applied to investigate and optimize the preparation parameters, including surfactant type (CTAB, PVP, P123), pH (9, 10, 11), aging temperature (40, 60, and 80 °C), and aging time (0, 15, 30 h). The obtained outcomes revealed that the optimized sample displayed a mesoporous nanocrystalline structure with an appropriate BET area (72.6 m2 g−1) and pore volume (0.17 cm3 g−1), and its maximum methane conversion was 80.8% at 700 °C. The results indicated that the Taguchi procedure was impressive in the optimization of the synthesis parameters, and the error value between the predicted value and the actual value was lower than 4%. The physicochemical characteristics of the optimized sample were assessed based on the XRD, BET, H2-TPR, FTIR, TGA/DTA, FESEM, and TPO analyses. Furthermore, the influence of calcination temperature was investigated on the textural properties and catalytic performance of the selected catalyst. The stability experiment of the samples showed that the NiO(50)/FeAl2O4 catalyst calcined at 600 °C was utterly stable for 300 min time on stream. Also, the effect of the processing parameters (GHSV, feed composition, and reduction temperature) was evaluated on the catalyst stability and amount of the deposited carbon on the catalyst surface of the optimum NiO(50)/FeAl2O4 catalyst.

HiPIMS co-sputtering for the increase of the mechanical properties of arc deposited TiN coatings

Relatively few studies have addressed the use of vacuum arc evaporation (VAE) in conjunction with high-power impulse magnetron sputtering (HiPIMS), due to differences in the respective pressure requirements. This paper describes the use of HiPIMS-enhanced VAE (HEVAE) technology for the deposition of TiN coatings on tungsten carbide and silicon wafers. We determined that HiPIMS could reduce the formation of macro-particle (MP) defects, while enhancing hardness and adhesion strength. Electron microscopy results revealed that both the quantity and size of MPs decreased inversely with HiPIMS power. Under the highest HiPMS power (4 kW), we observed a notable decrease in the size of columnar crystals and a significant increase in the number of nanocrystalline structures. The formation of nanocrystals enhanced hardness by reducing the probability of dislocations. Overall, HiPIMS power of 4 kW proved optimal in terms of MP formation, hardness (32.1 GPa), and adhesion strength (137 N).

High-temperature active oxidation of nanocrystalline silicon-carbide: A reactive force-field molecular dynamics study

Flexible woven SiC ceramics are prone to accelerated fiber embrittlement under high temperature oxidation in dynamic oxygen environments. The nanocrystalline structure of the constituent fibers impacts the reaction kinetics and phase transformations during active oxidation. However, fundamental understanding and quantification of grain boundary effects on oxidation behavior in nanocrystalline SiC remain elusive when temperatures exceed 1500 K. This study deploys large-scale molecular dynamics simulations with a reactive force-field to elucidate the complex roles of atomic oxygen reservoir conditions and grain size on oxidation kinetics and the nature of oxides produced in both monocrystalline and nanocrystalline 3C-SiC between 1100 K and 2000 K. The simulations with dynamically replenished oxygen provide good agreement with oxidation kinetics and activation energies for the monocrystalline Si(100) and C(100) orientations published in the available literature. This study reveals that, by contrast, nanocrystalline SiC samples exhibit two distinct oxidation kinetics with a transition point at 1500 K due to surface melting, which is supported by experimental evidence. The introduction of a grain-boundary network produces a two-fold decrease in oxidation activation energies compared to monocrystalline SiC below 1500 K. Above 1500 K, however, the activation energies rise substantially due to the formation of a liquid Si phase at the SiC/Si oxide interface. It is shown that the stability of the interfacial liquid phase is promoted by incoherent grain boundaries in the crystalline SiC. These findings are important for the deployment of nanocrystalline SiC fibers in advanced thermal protection systems for high-temperature applications.

TiMoTa multi-component transition layer: Plasma in-situ diagnosis, mechanical properties and effect on diamond adhesion

The transition layer prepared on the cemented carbide surface through double glow plasma surface alloying (DGPSA) is believed to be an effective strategy to improve the adhesion between the diamond and cemented carbide. In this work, to fully reveal and understand the behavior of double glow discharge plasma, DGPSA processes were studied using optical emission spectroscopy (OES), and the effect of the as-prepared TiMoTa transition layer on the diamond growth mechanism and adhesion property was analyzed. The microstructure, composition, and adhesion properties of TiMoTa transition layers and diamond coating were analyzed using SEM, TEM, XPS, XRD, and Rockwell C indentation. The results indicated that the intensity of the plasmas (Ti, Mo, and Ta) remained stable with the deposition time with the increase of deposition temperature, the electron temperature remained in the range of 1 × 104–1.4 × 104 K during the deposition process. OES results showed that the TiMoTa transition layer with a high deposition rate and high performance can be prepared by selecting the appropriate deposition temperature and time through DGPSA technique. The TiMoTa transition interlayers with nanocrystalline structure can effectively restrain the out-diffusion of Co and the in-diffusion of C, thereby effectively improving the adhesion between diamond and cemented carbide. Hence, the TiMoTa transition layer prepared through DGPSA technique offers an effective way to develop a good adhesion diamond coating on WC-Co substrate.

Influence of Fe Doping on the Electrochemical Performance of a ZnO-Nanostructure-Based Electrode for Supercapacitors.

ZnO is a potential candidate for providing an economic and environmentally friendly substitute for energy storage materials. Therefore, in this work, Fe-doped ZnO nanostructures prepared using the microwave irradiation procedure were investigated for structural, morphological, magnetic, electronic structural, specific surface area and electrochemical properties to be used as electrodes for supercapacitors. The X-ray diffraction, high-resolution transmission electron microscopy images, and selective-area electron diffraction pattern indicated that the nanocrystalline structures of Fe-doped ZnO were found to possess a hexagonal wurtzite structure. The effect of Fe doping in the ZnO matrix was observed on the lattice parameters, which were found to increase with the dopant concentration. Rods and a nanosheet-like morphology were observed via FESEM images. The ferromagnetic nature of samples is associated with the presence of bound magnetic polarons. The enhancement of saturation magnetization was observed due to Fe doping up to 3% in correspondence with the increase in the number of bound magnetic polarons with an Fe content of up to 3%. This behavior is observed as a result of the change in the oxidation state from +2 to +3, which was a consequence of Fe doping ranging from 3% to 5%. The electrode performance of Fe-doped ZnO nanostructures was studied using electrochemical measurements. The cyclic voltammetry (CV) results inferred that the specific capacitance increased with Fe doping and displayed a high specific capacitance of 286 F·g-1 at 10 mV/s for 3% Fe-doped ZnO nanostructures and decreased beyond that. Furthermore, the stability of the Zn0.97Fe0.03O electrode, which was examined by performing 2000 cycles, showed excellent cyclic stability (85.0% of value retained up to 2000 cycles) with the highest specific capacitance of 276.4 F·g-1, signifying its appropriateness as an electrode for energy storage applications.

Reduction of Friction and Wear for AISI321 Stainless Steel through Surface Modification Using Nanocrystallization.

Through surface nanocrystallization and low-temperature ion sulfurization, the nanocrystalline/FeS thin film with excellent friction-reduction and antiwear properties was fabricated on the surface of AISI321 stainless steel. The nanocrystallization treatment formed the high hardness and active nanocrystalline structure on the surface of AISI321, with the harness increased from 4.6 GPa to 7.56 GPa. Furthermore, the significantly refined nanostructure strongly increased the concentration of S element in comparison with the single-sulfurized layer on the substrate. Tribological tests reveal that both the original AISI321 substrate and the single-sulfurizing-treated samples are subject to severe abrasion. Single nanocrystallization treatment can improve the wear resistance of AISI321, while the compound treatment can obviously improve the comprehensive tribological properties. The compound-modified layer presents excellent tribological properties with the lowest coefficient of friction (COF) of 0.33, which is related to the increased hardness of the substrate and increased thickness, density, and homogeneity of the sulfurized layer. Furthermore, a physical model is developed for the vacuum tribological behavior of the samples after different treatments. This model provides a reference for revealing the tribological mechanism of the compound-modified layer treated using surface nanocrystallization-assisted chemical heat treatment.

Biological Applications of Colloidal Nano Crystals Using the MOORA Method

Introduction: Nano crystals are collections of molecule that may be put together to generate crystalline forms of drugs that are covered in a thin layer of surfactant. Quantum dots offer a wide range of uses in biology imaging, bioengineering, and environmental research, but less so in biomedicine for drug delivery. Nano crystals are created as nano absences, which are tiny medication particles. For medications that are weakly soluble, nano crystal is a commercially feasible formulation. A flexible and all-purpose manufacturing technique for nano crystalline is wet milling. Several delivery methods have been devised using nano crystalline structures.

Nanocrystalline Ag–Cu–Al Alloy thin films with densely dispersed alumina particles prepared using reactive sputtering method with Ar–O2 mixed gas

As a first step to challenge the fabrication of highly O2-permeable Ag membranes, thin films of nanocrystalline Ag–Cu–Al alloys with densely dispersed Al2O3 particles were successfully prepared via reactive sputtering using Ar–O2 mixed gas. The effect of O2 partial pressure on the thin film structure during sputtering was investigated. A critical O2 partial pressure was required to obtain a nanocrystalline structure via simultaneous internal oxidation during sputtering. The critical condition was correlated with the flux ratio of O2 to Al impinging on the Ag film surface and the stoichiometric ratio of O to Al in Al2O3.

Boosting electro-Fenton performance by constructing a large-scale 3D-architected amorphous–nanocrystalline structure

Metallic glasses (MGs) catalysts have shown promise in Fenton-like reactions for environmental remediation. However, the challenge of balancing catalytic activity and recyclability has hindered their practical application. Here, we present a novel approach to fabricate a three-dimensional (3D) amorphous-nanocrystalline catalyst on Cu-foam using thermal spraying, which shows excellent catalytic activity-recyclability synergy. This method enables large-scale production of a 3D porous MG composite (referred to as 3DP MGC) without the need of post-treatment. The architected 3DP MGC exhibits exceptional electro-Fenton activity, surpassing the performance of most Fe-based catalysts reported to date, with a kinetic rate constant 1.4 times higher than that of the amorphous FeSiB MG ribbon. Furthermore, the 3DP MGC catalyst demonstrates excellent reusability, maintaining efficiency for over 60 cycles without decay. The excellent catalytic activity of the 3D-architected MGC is attributed to the galvanic coupling between the MG and α-Fe phases with a low grain boundary effect and accelerated electronic transfer kinetics, facilitating the generation of multiple reactive oxygen species. Additionally, the catalyst benefits from a sustainably active surface enriched with Fe(II) species, resulting in ultrahigh reusability. Finally, we demonstrate the exceptional environmental tolerance of the architected 3DP MGC catalyst, showcasing its high efficiency in degrading real oilfield wastewater and suggesting its potential for the 3D engineering of MG materials in catalytic applications.

Cutting Performance and Wear Mechanism of Multilayer Diamond‐Coated Tools

Monolayer and multilayer diamond films are deposited on WC‐Co cemented carbide by hot‐filament chemical vapor deposition. The growth characteristics of diamond coatings are analyzed. Cutting performance characteristics such as tool life and the stability of machining process in the machining of presintered ZrO2 are compared based on the variation of cutting speed and resultant cutting force, and workpiece surface roughness. For the monolayer diamond coatings, as the concentration of CH4 increases from 1% to 5%, the diamond crystal is transformed from micron columnar crystal to nanocluster crystal. The multilayer diamond coatings combine the advantages of micron‐ and nanocrystalline structures. The multilayer diamond‐coated tool exhibits longer service life and better machining quality. Because of the appearance of the brittle–plastic conversion mechanism, the surface integrity of ZrO2 processed by multilayer diamond‐coated tool is relatively high. As for the uncoated tool, the workpiece is mainly machined by brittle spalling. The interfacial stratified fracture system between the interlayers is proposed to be the toughening mechanism of the multilayer structure.

Cryogenic superelasticity and elastocaloric effect in a nanostructured Ti-Ni-Co alloy

We report a nanostructured Ti49.2Ni44.8Co6 (at.%) alloy that exhibits a fully recoverable tensile superelasticity (∼ 6%) with high critical stress (> 500 MPa) spanning low temperatures from -150 to -50 ∘C. An adiabatic temperature change reaches 10.7 K during fast unloading at -50 ∘C. The low-temperature tensile superelastic stress and adiabatic temperature change outperform most shape memory alloys. Moreover, both properties exhibit negligible degradation during dozens of stress cycles. We attribute these favorable functionalities to the enhanced thermodynamic stability of parent phase and the remarkable strengthening effect on the matrix by partially recrystallized nanocrystalline structure with dispersed Ti3Ni4 nanoprecipitates.

Effect of Magnetron Sputtering Power on ITO Film Deposition at Room Temperature

Magnetron sputtering in the medium frequency (MF) mode was used to obtain ITO films on glass substrates at room temperature in an oxygen-free environment. The effect of the magnetron sputtering power on the electrophysical properties and surface morphology of ITO films is studied. It is shown that the ITO film deposition rate depends linearly on the power of magnetron sputtering in the MF mode. It is found that ITO films have a predominantly nanocrystalline structure at a magnetron sputtering power of more than 100 W. Increasing the sputtering power leads to an increase in surface roughness from 13.5 to 24.6 nm and grain size from 11.7 to 27.5 nm in the ITO film. The minimum resistivity of the ITO films is 6.82 × 10–4 Ω cm at the concentration and mobility of charge carriers of 2.48 × 1020 cm–3 and 36.8 cm2/V s, which corresponds to the optimum power of magnetron sputtering of 200 W. The results obtained correspond to a high level of surface resistance values for ITO films (34.1 Ω/□), which can be used to form transparent conducting electrodes in solar cells and memristors, both on glass and flexible substrates.

TEM Study of a Layered Composite Structure Produced by Ion-Plasma Treatment of Aluminum Coating on the Ti-6Al-4V Alloy

Using the methods of transmission electron microscopy and energy-dispersive spectroscopy, we study the microstructure and phase composition of the coating and modified intermetallic layers obtained in a Ti-6Al-4V alloy by the deposition of the Al coating and subsequent processing in low-pressure non-self-sustained arc discharge plasma (CIPT—complex ion-plasma treatment). The deposition of the aluminum coating on the Ti-6Al-4V alloy is accompanied by the formation of a layered and a gradient microstructure: nanocrystalline near the “coating/substrate” interface and ultrafine-grained in the outer part of the aluminum coating, with α-stabilized region of ≈5 µm thick in the surface layer in base titanium alloy. After the CIPT, the coating and the surface of the base titanium alloy have a layered morphology: each of the layers possesses different grain structure and composition. In the direction from the outer surface of the specimen to the base material, the following phase sequence has been confirmed by diffraction and elemental analysis: TiAl3 → TiAl3 + nc-(Al(Ti) + α-Ti) → nc-(Al(Ti) + α-Ti) → TiAl3 → TiAl3 + TiAl → TiAl → Ti3Al → α-Ti alloy → (α + β)-Ti alloy. The nanocrystalline aluminum layer, which has been formed during the deposition of the aluminum coating, does not undergo phase transformation and recrystallization under the CIPT. Nanocrystalline structure can favor the interdiffusion of the elements between the coating and base material, and stimulate phase transformation in coarser grains situated under and over it.

Phase transformation, thermal behavior, and magnetic study of new (FeSiBP)100-XCuX glassy alloys obtained by melt-spinning in air

In the current work, a new variation of the FeSiBPCu system with good glass forming ability and soft magnetic properties was developed and investigated. The effect of copper addition on the FeSiBP base alloy was studied in the system (Fe0.77Si0.08B0.1P0.05)100-xCux with x = 0, 0.25, 0.5, 0.75 and 1.0 at%. Microstructural evolution upon the annealing process was evaluated by XRD and TEM, revealing the formation of α-Fe(Si), Fe2B and Fe3(B,P) crystalline phases. VSM allowed to determine that the combination of chemical composition and microstructure with the best soft magnetic properties after the annealing corresponds with the alloy with 0.75% Cu. In addition, activation energy for glass transition and the first crystallization event were calculated using the Kissinger method. The research findings demonstrated that maintaining the relationship between the main elements, it is possible to keep the good glass forming ability with the possibility of developing a nanocrystalline structure with soft magnetic performance.Graphical abstract

Self-lubricating behavior of a PdCuNiP glassy alloy by in-situ nanocrystallization during dry friction

In the present work, dry-sliding behavior of a PdCuNiP bulk glassy alloy (BGA) was studied and compared with that of a ZrAlNiCu BGA. The PdCuNiP BGA exhibits a 2-fold smaller coefficient of friction (COF) and a 100-fold lower wear rate than those of the ZrAlNiCu BGA, although the PdCuNiP BGA shows the smaller hardness and fracture toughness. The unprecedented low COF and wear rate of the PdCuNiP BGA stem from in-situ formation of an amorphous/ultrafine nanocrystalline structure layer on the wear-scar surface during the dry sliding. The Von-Mises stress simulation mapping in the contact area reveals that the effect of stress and deformation is not the primary cause for the nanocrystallization. The model calculated frictional heat generated during the friction process causes the in-situ nanocrystallization, which increases the hardness and strength of surface layer. The self-lubrication effect results from the effective suppression of the sliding-induced plastic deformation and surface roughening.

The Microstructure Evolution and Formation Mechanism of Gradient Nanostructure Prepared on CrCoNi Medium-Entropy Alloy.

An equiatomic CrCoNi medium-entropy alloy was subjected to high-energy shot peening (HESP) to fabricate a gradient nanostructure (GNS) in this work. The microstructures of the GNS samples at different depths within the deformed layer were thoroughly investigated. The microstructure exhibited a transformation from unstressed coarse grains to deformed coarse grains, followed by the formation of ultrafine grains, and ultimately reaching a final nanocrystalline structure with a uniform size of approximately 50 nm. Detailed structural analysis indicated that the deformation process was primarily influenced by the interaction between dislocations and deformation twins, which was attributed to the low stacking fault energy (SFE) of the alloy. The nanocrystalline mechanism was divided into three stages. In the coarse-grained deformation stage, the dislocation band divided twin/matrix lamellae into sub-segments, and the cross twin divided coarse grains into ultrafine grains simultaneously. In the ultrafine grain deformation stage, dislocations were arranged around the deformation twins in order to break the twins to form incoherent boundaries, destroying the coherent relationship between the twin and matrix. Finally, in the nanocrystalline deformation stage, the nanocrystalline structure was further divided into smaller segments to accommodate additional strains through the interaction between dislocations and twins.

Development and Research of New Hybrid Composites in Order to Increase Reliability and Durability of Structural Elements

Hybrid composite materials can successfully solve the problems of reliability, durability, and extended functionality of products, components, and details, which operate under conditions of multifactorial influences (temperature, force, and deformation). The authors have developed a hybrid composite high-entropy AlCoCrCuFeNi material and ceramic cBNCoMo(B4CCoMo) layer. The formation of hybrid composites was carried out using new technology. This technology includes high-energy machining, high-velocity oxygen-fuel spraying in a protective environment, high-temperature thermomechanical treatment, and heat treatment. The use of the developed technology made it possible to increase the adhesive strength of the composite layers from 68 to 192 MPa. The authors performed an assessment of the structural parameters of the composite layers. The assessment showed that the composite layers had a nanocrystalline structure. The research included mechanical tests of the hybrid composites Hastelloy X (NiCrFeMo)—AlCoCrCuFeNi—cBNCoMo and Hastelloy X (NiCrFeMo)—AlCoCrCuFeNi—B4CCoMo for cyclic durability (fatigue mechanical tests) and friction wear. The use of surface-layered materials AlCoCrCuFeNi—cBNCoMo and AlCoCrCuFeNi—B4CCoMo in the composition of hybrid composites significantly increased cyclic durability. The use of surface-layered materials in the composition of hybrid composites made it possible to reduce wear intensity. The test results show that the developed composites are promising for use in various industries (including oil and gas), where high strength and wear resistance of materials are required.
