Summary: Particle breakage has significant effects on particle size, shape, surface roughness, and co-ordination number, which in turn affects the macro-mechanical behavior such as compressibility and shear strength. This study investigated the one-dimensional compression behavior of quartz sands with different initial void ratios. The results showed that extensive particle breakage resulted in the definition of a unique normal compression line, with denser samples exhibiting higher yield stress.

Summary: Investigates the phenomenon of the formation of sand heaps from pouring granular material, finding that the critical size of the heap is linearly related to the input flux and proportional to the square root of the feeding height. Experimental evidence shows that the flowing granular phase forms a "wedge" on top of the static phase, and controlled experiments can predict the critical size in situations where the feeding height decreases as the pile increases in size.

Summary: This study explores the assignment problem for the dichotomy spectrum of linear continuous time-varying systems on the half-line. It demonstrates that uniform complete controllability is a sufficient condition to adjust the closed-loop system's spectrum within a Hausdorff neighborhood of the free system's spectrum using appropriate linear feedback. The norm of the linear feedback matrix is bounded by the Hausdorff distance between these two spectra with a constant multiplier.

Summary: Enzyme engineering is crucial for various applications, including biotechnology, chemical manufacturing, pharmaceuticals, and environmental remediation. Traditionally, protein design focused on active site residues for desired catalytic properties, but recent studies show that structural elements beyond the active site, like subunit-subunit interactions and flexible loops, also impact enzyme catalysis. This is particularly true for Rieske oxygenases, where the architectural features inside and outside the active site play a significant role in catalysis. Therefore, future Rieske oxygenase engineering efforts should consider these features.

Summary: In this study, an active Fe(III) oxyhydroxide-Mn(IV) oxide/3D graphene oxide (GO) gel composite was successfully fabricated through a simple hydrothermal reaction. The optimized Fe-Mn/GO composites showed superior performance with removal efficiencies of over 90% for As(III) at pH 7.0 and close to 97% for As(V) at pH 5.0. After stable and continuous operation for 20 days, the effluent concentration of arsenic could be reduced to below 10 μg/l. This research is of great significance for addressing the challenges of nanoparticle aggregation, metal leaching, and insufficient removal efficiency in practical applications.

Summary: The electrochemical chlorination of urea to CO2 and N-2 end-products, via active-chlorine-mediated oxidation under nearly neutral conditions, is an effective treatment for medium-concentrated urea-containing wastewater. A novel flow reactor integrated with three-dimensional hierarchically porous Ru/RuO2 architectures anchored on a Ti mesh was designed. The hierarchically macroporous electrode can create sufficient exposure of catalytically active sites and facilitate the microscopic mass transport and diffusion inside the active layer, thereby contributing to the increased removal efficiency of urea-N and ammonia-N.

Summary: The integration of pre-treatment methods with low pressure-driven ultrafiltration has been proven effective in reducing disinfection by-products in drinking water. In this study, a low dose peroxone assisted alkaline hydrolyzed polyacrylonitrile UF-membrane system was explored for its efficiency in removing dissolved organic matter and regulated DBPs. The HPAN membrane displayed high flux recovery and comparable removal efficiency to the NF-3 membrane. Additionally, the H2O2/O3-HPAN system significantly reduced the aromatic and fluorescent content of the DOM and removed a high percentage of THMs, HAAs, and DBPs formation.

Summary: This paper focuses on the functionalization of double positively charged polyethylenimine (PEI)/Zr4+-polyamide (PA) nanofiltration (NF) membrane. The study evaluates the properties and performance of prepared PEI/Zr4+-PA NF membrane in removing aquatic contaminants and its antifouling ability. Results show that loading Zr4+ improves the hydrophilicity and removal behavior of the membrane when exposed to high concentrations of contaminants. The effectiveness of the membrane is not affected by factors such as high filtering degree and filtration cycle, and antifouling ability can be further improved by continuously loading Zr4+.

Summary: This study investigates the interaction between O3 and amorphous alum flocs formed during flocculation at neutral pH using a conventional coagulant (alum). It was found that O3 promotes the transition of the in-situ formed alum flocs from tetrahedral Al to octahedral Al structures, facilitating the crystallization process. The involvement of surface functional groups of amorphous Al flocs in O3 catalytic oxidation enhances the performance of the subsequent dual-membrane filtration process in terms of fouling alleviation and effluent quality improvement.

Summary: The long-term performance of graphene oxide (GO) membranes in practical water treatment conditions was investigated. Two representative GO membranes (V-GO and P-GO) with different surface properties were evaluated for their filtration performance and biofilm characteristics. The results showed that both membranes achieved sustainable water purification, with V-GO forming a highly heterogeneous and porous biofilm and P-GO forming a thin but dense structure. The microbial community analysis revealed different bacteria compositions in the biofilms of the two membranes. The findings highlight the importance of considering membrane surface properties in designing membrane systems for long-term water treatment.

Summary: Drinking water supply in rural areas is a challenging issue, and low-cost, efficient water treatment processes are needed to provide safe and affordable drinking water. This study proposes and evaluates a bubbleless aeration BAC (ABAC) process with a hollow fiber membrane (HFM) assembly, which improves dissolved oxygen (DO) throughout the filter and enhances DOM removal efficiency. Results show that ABAC significantly increases DOC removal and decreases disinfection byproduct formation compared to a comparable filter without aeration. The proposed ABAC treatment, with its various advantages, is well-suited for decentralized drinking water systems in rural areas.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
