Sustainably flexible and free-standing organic carbonyl potassium salt with continuous conductive network as high-performance anode in K-ion batteries

Developing suitable electrode materials with high flexibility, superior cyclic performance and low-cost have been the new topic and difficulty in the up-coming wearable flexible device. Herein, organic potassium terephthalate (K2TP) with MWCNTs and conductive polymer PEDOT:PSS co-coated K2TP/2MWCNTs/PP composite endowing continuous conductive network, was initially developed as a pliable and free-standing anode material for potassium ion batteries. By analyzing the internal microstructure, external topography and varies electrochemical characterization of the prepared samples, the incorporation of reasonable MWCNTs and PEDOT:PSS allows for the construction of a continuous conductive network with a large specific surface area, the creation of an effective electron transfer channel, an improvement in the kinetics of K+ diffusion and the maintenance of structural integrality. A preeminent specific capacity of 154.3 mAh g−1 can be maintained after 100 cycles at the current density of 50 mA g−1, prevailing over the majority of claimed anode materials employed in K-ion batteries. Furthermore, a high-performance all-organic full battery based on flexible anode and cathode material was successfully assembled delivering an extraordinary energy density of 320 Wh Kg−1. These results can put forward the practical application of organic electrode materials in systems for massive-scale energy storage.

The Dissolvable Alginate Fiber Network Produced Via the Immersed Microfluidic Spinning

Abstract Pore size and pore interconnectivity that characterize the topology of the vascular networks in tissue constructs are critical to healthy cell behavior and tissue formation. While scaffolds with hollow channel structures (that precede vascularization of tissue engineering constructs) have gained significant attention, still creating the hollow channel networks within various cellular matrices such as cell-laden hydrogels, remain a slow process limited by the speed of material extrusion of 3D printing techniques for the deposition of sacrificial fibers. To address the issue of low throughput for sacrificial fiber production and placement, we propose to utilize the micromanufacturing technique of the immersed microfluidic spinning. This study discusses the optimization of the topology of the sacrificial calcium alginate microfibers as a function of alginate concentration and the gauge of the needle used in the immersed fluidic spinning. An important parameter of the fabricated fiber network is the size of the loops produced via the immersed fluidic spinning. The nutrients should diffuse from the fluidic channel to the center of the loop. We demonstrate that the loops with radii between approximately 1600 and 3200 μm can be produced with needle of 30 gauge for alginate concentrations between 1% and 8%. Fiber diameters are also characterized as a function of needle gauge and alginate concentration. We demonstrate the creation of a hollow channel in a Methacrylate gelatin (GelMA) sample by dissolving the alginate fibers produced via the immersed fluidic spinning method. Finally, viability of the fibroblast cells in GelMA is qualitatively studied as a function of the distance of the cells from the outside boundary of the gel (where the cell media is located). As expected, the cell viability falls as the distance from the outer boundary of the gel increases.

Building Sustainable Cities Along the Dimensions of Democracy

This research seeks to make evident the intimate connection between sustainable development and democratic concretization, characterized here not only by the electoral process, but also by a permanent dialogical relation between the State and civil society. The emphasis of the reflection is set on the local aspect with the purpose of studying forms of effective democratization of the urban space, and the possible means of achieving it. The starting point for this work is the hypothesis that the city is a space and territory in dispute, which reflects in contrasting expressions such as being the place of violations and denial of a dignified life, and yet, an environment of expansion of dignities and liberties. Therefore, what will be analyzed are the possible strategies to be elaborated, considering democratic planning and transforming institutional proposals, in order to enable the creation of a formal channel which effectively instrumentalizes dialogue with city population, considering all participants of the scenario, from the individual, to the private sector, up until, finally, the public power, which manages the public space. The following research is qualitative and deductive, adopting the procedures of bibliographic and documental research.

METHODOLOGICAL ASPECTS OF THE STUDY OF THE RATE CONSTANT OF THE REACTION OF HYDROCHLORIC ACID WITH CARBONATE FORMATION ROCK

Hydrochloric acid treatments are most widely used to intensify oil production from carbonate reservoirs. But despite a wealth of experience in the use of hydrochloric acid treatments, the results of treatments often do not reach the planned values of oil production growth. Efficiency of acid exposure depends on the depth of penetration of the hydrochloric acid solution into the thickness of the productive reservoir, which, in turn, is conditioned by the degree of reactive activity of the acid composition. It is important to achieve the creation of filtration channels in the zone remote from the borehole, which will lead to an improvement in the filtration characteristics of the bottomhole formation zone to the proper extent. Therefore, in order to achieve the best result when planning acid exposure, it is important to consider the geological and physical properties of the object to be treated and select the appropriate formulation of the acid composition.
 The reaction rate constant is a parameter that allows you to take into account the compatibility of the acid composition and the geological and physical conditions of the productive reservoir. This parameter characterizes the rate of reaction between substances. However, a generally accepted method for studying the kinetic parameters of the reaction of acid compositions with carbonate formation rock has not yet been developed, which leads to low reproducibility of experimental results. The purpose of the research presented in the article is to develop a methodology for studying the kinetics of the reaction of hydrochloric acid with carbonate rock and to create a unified approach to determining the reaction rate constant, characterized by the greatest reproducibility of the results. The experimental part of the work was carried out in several stages, including the preparation of core material, the preparation of hydrochloric acid solution and its thermostating, and the further conducting of four series of studies at the PIK-OSG volumetric setup to determine the optimal acid-rock ratio, identify the optimal weight of the core material and establish the optimal coarseness of its grinding.
 The obtained results of experiments on the study of methodological aspects of the study of the rate constant of the reaction of hydrochloric acid with carbonate rock showed that the experiments should be conducted in conditions of an excess of rock relative to acid, in this case the mass of the core sample and the coarseness of the grinding of the core material will not affect the error in determining the reaction rate constant.

Modification of polyacrylonitrile TFC-FO membrane by biowaste-derived hydrophilic N-doped carbon quantum dots for enhanced water desalination performance

Effective membranes are critical for enhancing the productivity of the forward osmosis (FO) desalination process. In this work, a straightforward approach is presented for constructing a hydrophilic and high-flux thin film composite FO (TFC-FO) membrane onto a polyacrylonitrile (PAN) sublayer. To this purpose, biowaste-derived nitrogen-doped carbon quantum dots (BWD-NCQDs) were incorporated into the polymeric structure of the TFC selective layer, which improved surface hydrophilicity and caused the creation of more water channels, resulting in better intrinsic transport properties. In both FO and pressure retarded osmosis (PRO) membrane orientations, TFC-FO membranes containing 0.01–0.1 wt% of BWD-NCQDs showed better water permeation and NaCl rejection than the pristine TFC membrane. In the presence of 0.05 wt% of BWD-NCQDs, water flux increased by 54.7 % and reached 24.6 Lm−2 h−1, and reverse solute flux decreased by 43.3 % to 3.81 g−2 h−1 compared to the pristine membrane. The optimum membrane also showed better fouling and water desalination behavior. Therefore, modification of the membranes by hydrophilic BWD-NCQDs represents superior performance in the FO processes. This study demonstrates the potential of using hydrophilic NCQDs derived from biowaste materials to incorporate into TFC membranes and improve their FO proficiency in water desalination.

The Production and Marketing Constraints Faced by Ginger and Turmeric Growers in Assam's Hill and Plain Region, India

The present study was conducted to know the constraints perceived by Ginger and Turmeric growers in terms of production and marketing in the hill and plain district of Karbi Anglong and Jorhat of Assam during September 2021. Using Multistage Stratified Random Sampling, the constraints perceived by 252 respondents from both districts were tabulated and ranked accordingly. The major constraints that affected the production and marketing of ginger and turmeric in the hills were low adoption of better and improved production practices and technology, and the presence of middlemen/ local traders respectively whereas, for the plain region, the major constraints that affected production and marketing of ginger and turmeric were unfavorable weather conditions and poor market infrastructure respectively. As Assam is a major hub for ginger and turmeric production, policies should aim at providing better quality planting materials, provision of proper market infrastructure, creation of a “spices park” and creation of a proper export channel.

Creation of a Vivaldi-Based Circular Antenna Array for Broadband Relay Channels

Introduction. Unmanned aerial vehicles (UAVs) are rapidly gaining in popularity. The UVA development requires active antenna systems capable of forming a narrow beam of the main lobe of the radiation pattern. Although numerous studies have considered specialized antenna arrays with a wide range of scanning angles, the location of such systems on UAVs remains under-investigated. The development of such arrays for UAVs will enable the creation of a secure relay broadband channel with a few repeaters.Aim. Development of a broadband antenna array for UAVs with the possibility of setting the main lobe of the radiation pattern in any direction of the azimuthal plane, for use in relay tasks.Materials and methods. An emitter model and a circular antenna array on its basis was developed in the Ansys HFSS electromagnetic modeling package.Results. The dependence of the directional coefficient and the gain for an array consisting of 8 and 16 elements was shown. Voltage standing-wave ratio dependences and directivity patterns that satisfy the conditions of retransmission in a wide-frequency band using UAVs were obtained. Recommendations on the number of active elements in a circular antenna array that ensure the maximum gain (directivity) were formulated.Conclusion. Technical solutions that can be used in the development of UAVs are proposed. The system can be further improved by optimizing the antenna array elements and using a cylindrical or hemispherical array.

Laponite nanoclay-modified sacrificial composite ink for perfusable channel creation via embedded 3D printing

Vascularization is a major hurdle in developing in vitro thick tissue constructs. Fortunately, embedded sacrificial printing has emerged as a promising technology to fabricate perfusable channels. The objective of this study is to develop a Laponite nanoclay-modified polyvinyl alcohol (PVA) sacrificial composite ink that has improved printability, minimized interdiffusivity, and satisfactory post-printing removability during embedded printing of perfusable channels. With the addition of Laponite nanoclay, not only the printability of the PVA-Laponite nanoclay composite ink is significantly improved, but also the interdiffusion between the gelatin precursor solution and the PVA-Laponite nanoclay composite ink is largely mitigated. The diffusion of the gelatin precursor solution into the PVA-Laponite nanoclay composite ink is of great importance for printing controllable perfusable channels since the diffused gelatin may cross-link as the gelatin composite matrix does during and after printing, resulting in residual gelatin gel in the channel and altered channel dimensions. In particular, the PVA-2.0% Laponite nanoclay sacrificial ink shows good printability and minimized interdiffusivity while maintaining good post-printing removability, which can be a good sacrificial composite ink for thick perfusable tissue creations. The channel diameter reduction due to the gelatin solution diffusion can be satisfactorily predicted based on the unidirectional diffusion model. This study further demonstrates the feasibility of using the proposed sacrificial ink for vascular tissue engineering applications.

Exploring the role of 2D-C2N monolayers in potassium ion batteries.

In recent years, undivided attention has been given to the unique properties of layered nitrogenated holey graphene (C2N) monolayers (C2NMLs), which have widespread applications (e.g., in catalysis and metal-ion batteries). Nevertheless, the scarcity and impurity of C2NMLs in experiments and the ineffective technique of adsorbing a single atom on the surface of C2NMLs have significantly limited their investigation and thus their development. Within this research study, we proposed a novel model, i.e., atom pair adsorption, to inspect the potential use of a C2NML anode material for KIBs through first-principles (DFT) computations. The maximum theoretical capacity of K ions reached 2397mAhg-1, which was greater in contrast with that of graphite. The results of Bader charge analysis and charge density difference revealed the creation of channels between K atoms and the C2NML for electron transport, which increased the interactions between them. The fast process of charge and discharge in the battery was due to the metallicity of the complex of C2NML/K ions and because the diffusion barrier of K ions on the C2NML was low. Moreover, the C2NML has the advantages of great cycling stability and low open-circuit voltage (approximately 0.423V). The current work can provide useful insights into the design of energy storage materials with high efficiency. In this research, we used B3LYP-D3 functional and 6-31 + G* basis with GAMESS program to calculate adsorption energy, open-circuit voltage, and maximum theoretical capacity of K ions on the C2NML.

Indocyanine green has a well established use in the evaluation of bowel perfusion, however, use has not been reported in catheterizable channels. Our aims were to develop a standardized protocol for using ICG in the creation of catheterizable channels and establish perfusion patterns of the channels. METHODS: A standardized protocol for the use of ICG in catheterizable channel creation was developed in an adaptive process in this single institution pilot study. Stryker’s SPY PHI system and SPY-QP quantification system were used. SPY-QP allowed for quantification of ICG uptake in the channel relative to healthy bowel. The standardized protocol is described in figure 1. RESULTS: ICG was used in the creation of 3 new appendicovesicostomies and 1 channel revision. Overall, perfusion to the channel decreased with increasing mobilization, but degree of decrease varied between patients. The median ICG uptake went from 85.5% immediately after stapling the appendix to 63.5% when examining the subfascial channel after maturing and 27% at the stoma. In the one revision, ICG clearly delineated an area of poor perfusion in the distal channel after complete mobilization of the channel off the skin and fascial attachments. CONCLUSIONS: The standardized protocol for use in catheterizable channels was successfully implemented. In the channel revision, ICG clearly delineated the area of distal hypoperfusion after channel takedown. ICG can provide surgeons with an objective assessment of channel perfusion rather than relying on subjective assessment alone.

Some pediatric urologists do not routinely use NSAIDs for fear of causing acute kidney injury (AKI). While previous studies have demonstrated the safety and efficacy of NSAIDs in children, safety after lower urinary tract reconstruction has not been well characterized. Using the Kidney Disease Improving Global Outcomes (KDIGO) criteria for AKI (increase in creatinine ≥0.3 mg/dL or increase in creatinine ≥1.5× baseline or urine output <0.5 mL/kg/hr for 6 hours), we hypothesized there would be a difference in incidence of postoperative AKI between patients who did and did not receive NSAIDs after these operations. METHODS: Patients 2–18 years old who underwent lower urinary tract reconstruction (i.e., bladder augmentation and/or creation of a catheterizable channel) from 2009 to 2021 and had documented urine were reviewed. CKD and stage were calculated from creatinine and cystatin C within 6 months of surgery using the CKiD U25 equations. Patients who received NSAIDs were propensity matched on 19 characteristics in a 2:1 ratio with patients undergoing similar surgeries who did not receive NSAIDs in the operating room or in the first 6 hours postoperatively. The primary outcome was incidence of AKI during 48 hours after surgery. RESULTS: The unmatched cohorts included 260 patients. After propensity matching, there were no meaningful differences in most characteristics among 118 in the NSAID arm and 59 in the no NSAID arm. 54 CKD and 4 renal transplant patients were included. There was no difference in the incidence of postoperative AKI based on any KDIGO criteria (18.6% no NSAID vs 15.3% NSAID, p=0.71). Median postoperative opioids fell from 0.75 mg/kg in the no NSAID arm to 0.30 mg/kg morphine equivalents in the NSAID arm (p=0.02). Log-rank testing by Kaplan-Meier analysis demonstrated no difference in time to incidence of low urine output between the groups (p=0.38). In the whole population not stratified by NSAID use, no differences were seen in AKI between those with and without CKD (16.6% vs 16.4%). CONCLUSIONS: There was no difference in the incidence of postoperative AKI among patients who did and did not receive NSAIDs after lower urinary tract reconstruction. These results support that postoperative NSAIDs were an unlikely source of AKI and result in lower opioid usage, but also indicate a proportion of patients undergoing these operations may be susceptible to AKI, likely owing to underlying disease, longer operations, and fluid shifts.

METHODS: In our SB clinic, we surveyed consecutive adult patients (≥18 years old [y]) who underwent MACE creation at <18y (6/2018-1/2020). Utilizing the Decision Regret Scale, DR was categorized as: none (0), mild (1-25), moderate (26-50), strong (51-75), very strong (>75). We analyzed whether bowel management habits (catheterizations, flushing toilet time, and stool evacuation), bowel symptoms (fecal incontinence and leakage per MACE), or symptom bother impacted DR. Patient factors were assessed on exploratory analysis. Non-parametric tests and logistic regression were used. RESULTS: Of the 71 patients (52% male, 90% White) who met inclusion criteria, the median ages at survey participation was 24y and MACE creation occurred at 7y. Eighty-six percent had a ventriculoperitoneal shunt and 45% used a wheelchair. Median DR score was 0 and 58% without any DR. Of those with some DR, the majority were mild (28%) and moderate (11%) with few strong (1%) or very strong (1%).The majority of patients, 73%, were independently flushing a median 7 times/week and spending a median 1 hour on the toilet. DR was significantly associated with both time on the toilet >1 hour (p=0.02, OR 3.7, 95%CI [1.3-10.8]) and bother waiting for stool evacuation (p=0.02, OR 3.2, 95%CI [1.2-8.5]) (Table 1). Difficulty catheterizing was also associated with DR (p=0.02, OR=3.3, 95%CI [1.2-9.5]). On multivariate logistic regression, only catheterization difficulty was significantly associated with DR (p=0.05, OR 3.3, 95%CI [0.99-10.9]). Forty-six percent of patients experienced some degree of fecal incontinence and the majority (88%) were bothered by it. Neither incontinence nor MACE leakage increased DR (p≥0.22). On exploratory analysis, patient demographic factors were not associated with increased DR (p>0.3). CONCLUSIONS: The majority of adults with SB do not regret undergoing MACE creation as children. Those with DR have mild to moderate levels. Time on the toilet exceeding an hour, self-reported bother related to the time needed for flushing, and catheterization issues contribute to post-MACE DR.

Good Practices in Inter-Institutional Collaboration in Managing the Migrant Crisis

In 2021, Lithuania faced the challenge of managing the crisis of new type of migration across the Belarusian border, which threatened the security of the country and its citizens. A broad set of inter-institutional collaboration strategies and methods were used among the public institutions to address this crisis. Such inter-institutional collaboration has been a multifaceted and complex process, involving both known and new good practices. The aim of this article is to provide insights into good collaborative practices between the Lithuanian national defence and internal affairs systems in managing the migrant crisis. Following the expert interview results, the study identified three good practices of inter-institutional collaboration: (i) the creation of a single dissemination channel for the crisis response services, which ensured that all actors were in the same information field; (ii) the delegation of representatives of the institutions to teams at strategic, operational and tactical levels; and (iii) inter-institutional information sharing ensured good situational awareness at an early stage of emergency management. Lessons learned from the collaboration between the institutions of the national defence and internal affairs systems can be applied to improve inter-institutional collaboration in other areas. The research results can be used to enhance the process of such collaboration in addressing current emergency management issues and serve as a basis for effective and smooth emergency preparedness and response where inter-institutional synergy is needed.

Effect of Dopants on Laser-Induced Damage Threshold of ZnGeP2

The effect of doping Mg, Se, and Ca by diffusion into ZnGeP2 on the optical damage threshold at a wavelength of 2.1 μm has been studied. It has been shown that diffusion-doping with Mg and Se leads to an increase in the laser-induced damage threshold (LIDT) of a single crystal (monocrystal), ZnGeP2; upon annealing at a temperature of 750 °C, the damage threshold of samples doped with Mg and Se increases by 31% and 21% from 2.2 ± 0.1 J/cm2 to 2.9 ± 0.1 and 2.7 ± 0.1 J/cm2, respectively. When ZnGeP2 is doped with Ca, the opposite trend is observed. It has been suggested that the changes in the LIDT depending on the introduced impurity by diffusion can be explained by the creation of additional energy dissipation channels due to the processes of radiative and fast non-radiative relaxation through impurity energy levels, which further requires experimental confirmation.

The Utilization of a Coupled Electro-Thermal-Mechanical Model of High-Voltage Electric Pulse on Rock Fracture

Our research proposes a unique coupled electro-thermal-mechanical model that takes electric breakdown and heterogeneity into account to show the mechanism of rock fracturing under high-voltage electropulses. Using finite element numerical software, the process of high voltage electrical pulse injection into the rock interior for breakdown is described, and the formation law of plasma channels during the electrical breakdown process is comprehensively analyzed in conjunction with the conductor particles present within the rock. On the basis of electrical, thermal, and mechanical theories, a coupled multi-physical field numerical model of rock failure under the action of high-voltage electrical pulses is developed, and a random distribution model is utilized to simulate the potential occurrence of conductor particles in the rock. Innovative numerical model indicates plasma channel creation in the rock-crushing process. Prior to the formation of the plasma channel, the temperature and stress are approximately 103 k and 10-2 MPa, respectively. Once the plasma channel is formed, the temperature and stress increase abruptly in a short time, with the temperature reaching 104 k and the stress reaching 103 MPa or higher. In addition, it is revealed that the breakdown field strength is the essential factor in plasma channel creation. The heterogeneity of the particles within the rock and the fluctuation in electrode settings are also significant variables influencing the creation of channels. The presented model contributes to a better understanding of the mechanism of rock fragmentation during high-voltage electrical pulses, which has substantial implications for oil exploration and mineral extraction.
