The interactions between human serum albumin (HSA) and the hemostatic components of the Chinese medicine Sanguisorbae Radix (SR), specifically phenolic acid compounds such as caffeic acid (CA), ferulic acid (FA) and their 1:1 mixture (1:1) were studied to investigate the molecular mechanism underlying the hemostatic effect of SR. Network pharmacology combined with the experimental and computational data revealed that HSA is one of the hemostatic targets to SR phenolic acids. SDS-PAGE and multi-spectroscopy demonstrated that the phenolic acids bind to site I on HSA, altering its structure and influencing its migration velocity. There is an observed synergistic effect upon the mixture of CA and FA. Quantum chemistry, molecular docking, and molecular dynamics simulations indicate that the binding of phenolic acids to HSA is stable, and variations in binding efficiency are associated with the hydrophobicity of the substituent at the C3 position of the side chain, and also, the key amino acids and functional groups for hemostasis of SR were identified, along with the active sites that contribute to the synergistic enhancement by phenolic acids. © 2024, The Authors.

A meticulous design of the local environment at the interface between active species and the support, aimed at optimizing the adsorption of H2O molecules and BH4⁻ anion, offers an ideal strategy for enhancing hydrogen generation via NaBH4 hydrolysis through dual activation pathways. Theoretical predictions based on d-band center analysis and electron transfer calculations suggest that introducing -OH functional groups induce charge redistribution, enhancing charge concentration on alk-Ti3C2 and facilitating the adsorption and activation of dual active species, H2O molecules and BH4⁻ anion. Inspired by these predictions, the optimized alk-Ti3C2/RuOx catalyst demonstrates the highest catalytic activity, achieving a hydrogen generation rate (HGR) of 9468 mL min⁻¹ gcat.⁻¹. Both experimental data and theoretical analyses confirm that the -OH functional groups promote charge enrichment on alk-Ti3C2, optimizing the adsorption of H2O molecules and BH4⁻ anion, and reducing the dissociation energy barrier of the *OH[sbnd]H-TS intermediate. This dual activation pathways mechanism lowers the activation energy for NaBH4 hydrolysis, significantly enhancing the HGR performance. These findings, guided by theoretical insights, establish alk-Ti3C2/RuOx as an efficient catalyst for NaBH4 hydrolysis and provide a strong foundation for future hydrogen generation catalyst designs.

This study aims to analyze the incorporation of widely available, cheap and biobased waste material such as wood charcoal which is used as filler in natural fiber reinforced polymer composites. Jute woven fabric (1 × 1 plain weave) was used as a natural fiber reinforcement, unsaturated polyester resin was used as matrix material, and wood charcoal powder used as bio-filler to manufacture various composite material formulations of 25% fiber weight fraction. The wood charcoal filler loadings were 4, 8, 12, 16 and 20 wt% in the polymer matrix of the composites. The developed composite formulations were tested in terms of mechanical and physicochemical properties. Improved tensile properties were revealed with a 4 wt% filler modification, compared to the reference (unmodified) polymer composite. Nonetheless, further increase of filler (8–20 wt%), led to lower mechanical properties. Thermogravimetric analysis showed increased thermal stability of the 4 wt% charcoal filler modified composite compared to the reference one.

Photocatalytic and photoelectrocatalytic H 2 O 2 production has been identified as a significant pathway within environmental pollution control, green energy, medical treatment, sterilization and disinfection. However, conventional single-material photocatalysts struggle to fulfill the stringent criteria of high efficiency, stability, cost-effectiveness, and responsiveness to visible light. The elevated recombination rates of photogenerated charge carriers, coupled with the suboptimal utilization of visible light, have collectively constrained the photocatalytic and photoelectrocatalytic H 2 O 2 production. Heterojunction catalysts for the production of H 2 O 2 has become a focal point of research. This review commences by elucidating the fundaments underlying the photocatalytic and photoelectrocatalytic H 2 O 2 production. Subsequently, it delineates the distinctive electron transfer mechanisms of Z-scheme and S-scheme heterojunctions, which exhibit enhanced efficiency in the photocatalytic and photoelectrocatalytic H 2 O 2 production, along with a summary of strategies for the improvement of photocatalyst and photoelectrocatalyst performance. Furthermore, this review also outlines the latest fabrication strategies, state-of-the-art in-situ characterization techniques, machine learning and density functional theory (DFT) simulations for Z-scheme or S-scheme catalysts for the photocatalytic and photoelectrocatalytic H 2 O 2 production, and briefly describes the multifunctional applications in H 2 O 2 production. Ultimately, the review contemplates the prospective developmental trajectories and application potential of these heterojunction configurations for the photocatalytic and photoelectrocatalytic H 2 O 2 production.

This paper presents the development of a local train set aiming to augment the number of fleets presently the Philippine National Railways (PNR) provides. While importation has been the normal practice to supplement trains in the country's railway lines, this outsourcing is becoming more and more impractical as localization provides compelling advantages of cheaper cost and easier troubleshooting and maintenance. The train is composed of five (5) coaches which is powered by either generator set and/or batteries setting up the hybrid system. The coach assembly was designed using Solidworks and underwent stress analysis to verify its compactness and credibility. The addition of load sharing and regenerative braking technology furthers energy efficiency. To establish interaction with minimal wirings among systems making up the train set, a control system utilizing Programmable Logic controller (PLC) and Human-Machine Interface (HMI) with CC-Link Central System was installed. Performance testing and Reliability-Availability- Maintainability-Safety (RAMS) validation wrapped up the development securing the train set functionality and commercial viability.

This study presents a locally designed and developed semi-permanent coupler for the DOST-MIRDC's train consisting of five 12-meter-length coaches. Using the Computer-Aided Design (CAD) software, the capability of the coupler for tension and compressive loads were considered. The calculation for the compression load of 1000 kN was required to pull the train in case of emergency towing. The CAD-modelled coupler was then simulated and analyzed using Solidworks software. The simulation was focused only on the collapsible elements for the compression load and the flange, rods, and nuts for the tension load. Using a 2000-kN Test of Metallic Products at MIRDC, the proof load test and breaking load test of 500 kN and 925.61 kN were respectively attained. The result of the tension load testing shows that the designed and fabricated semipermanent coupler is capable of withstanding load of 100 kN with a significant tolerance.

We hypothesized that balancing the content of exogenous amino acids, especially lysine, to reduce protein content in swine diets could reduce nitrogen(N) pollution associated with animal husbandry. Two experiments(45 d each experiment) were performed on weaned piglets(Duroc x Landrace x Yorkshire,28 d of age) to test this and to determine the optimal lysine to crude protein(Lys:CP) ratio in diet. In Exp. 1,12 piglets(6 replicates [n = 6]) were fed diets containing different levels of CP(17% and 20%) but the same level of Lys, Increased CP content resulted in significant increases(P < 0.05) of average daily gain(ADG), average daily feed intake(ADFI), and body weight(BW);but did not affect the feed to gain ratio. In Exp. 2,24 piglets(8 replicates [n = 8]) were fed 1 of 3 diets as follows: 1) 20% CP with a regular Lys:CP ratio(6.23%, control);2) 17% CP with a reduced Lys:CP ratio(6.14%, LL);or 3) 17% CP with a standard Lys:CP ratio(7.32%, SL). The ADG, final BW, serum concentrations of growth hormone and insulin-like growth factor-1, villus height in the jejunum, and villus height to crypt depth ratio were the lowest in piglets fed LL diet, whereas blood urea N concentration was the lowest and the value of lipase activity was the highest in the piglets fed SL diet. The SL diet did not affect growth performance,intestinal morphology, or serum hormone concentrations, indicating that reduced dietary N with a high Lys:CP ratio can efficiently reduce dietary N excretion without negatively affecting weaned piglets.

Recent years have witnessed a surge in research on aqueous zinc-ion batteries (AZIBs) due to their low cost, stability, and exceptional electrochemical performance, among other advantages. However, practical manufacturing and deployment of AZIBs have been hindered by challenges such as low energy density, significant precipitation-related side reactions, slow ion migration, and dendritic growth. Addressing these issues and enhancing the practical application of AZIBs necessitates the development of novel materials. Carbon dots (CDs), with their distinctive structure and superior electrochemical properties, represent an innovative class of carbon-based materials with broad potential applications for optimizing AZIBs' performance. This study offers a comprehensive review of how CDs can address the aforementioned challenges of AZIBs. It begins with an overview of AZIBs composition and mechanism before delving into the classification, preparation techniques, and functionalization strategies of CDs. The review also thoroughly summarizes the sophisticated roles of CDs as modifiers in electrolytes and electrodes, both positive and negative, and briefly discusses their potential application in membranes. Additionally, it provides a summary of current issues and difficulties encountered in utilizing CDs in AZIBs. This review aims to provide insights and guidance for designing and manufacturing the next generation of high-performance AZIBs.

Task-free functional connectivity in animal models provides an experimental framework to examine connectivity phenomena under controlled conditions and allows for comparisons with data modalities collected under invasive or terminal procedures. Currently, animal acquisitions are performed with varying protocols and analyses that hamper result comparison and integration. Here we introduce StandardRat, a consensus rat functional magnetic resonance imaging acquisition protocol tested across 20 centers. To develop this protocol with optimized acquisition and processing parameters, we initially aggregated 65 functional imaging datasets acquired from rats across 46 centers. We developed a reproducible pipeline for analyzing rat data acquired with diverse protocols and determined experimental and processing parameters associated with the robust detection of functional connectivity across centers. We show that the standardized protocol enhances biologically plausible functional connectivity patterns relative to previous acquisitions. The protocol and processing pipeline described here is openly shared with the neuroimaging community to promote interoperability and cooperation toward tackling the most important challenges in neuroscience.
