Summary: This study investigates the effect of material surface chemistry and morphology on calcium carbonate crystallization from mixed electrolyte supersaturated solutions. The research findings suggest that EVOH copolymers with higher vinyl alcohol monomer content show better scaling resistance compared to polyethylene, and that polymer chain configuration and conformation play a crucial role in salt scaling resistance. Additionally, the incorporation of fluorine in polyamide thin film composite membranes does not affect salt scaling or solution de-supersaturation.

Summary: This study presents a method to inhibit the growth of CaCO3 and synthesize submicron particles in a chemical precipitation process, as well as investigates the characteristics of the synthesized particles under different conditions. The results indicate that colloidally stable submicron CaCO3 particles can be synthesized under specific conditions, with the presence or absence of additive Ca2+ ions affecting the particle size and composition.

Summary: This study reveals the formation of calcite mesocrystals through the attachment of amorphous calcium carbonate nanoparticles in the presence of inorganic zinc ions, inspired by the biomineralization process of sea urchin spine. It is also demonstrated that zinc ions can induce the formation of temporarily stabilized amorphous nanoparticles at a lower calcium carbonate concentration, which benefits the attachment and occlusion during calcite growth. The cation-mediated particle attachment crystallization improves our understanding of mesocrystal formation mechanisms and offers new opportunities for bioprocess inspired materials fabrication.

Summary: The cycling of marine particulate matter plays a crucial role in carbon sequestration in the deep ocean. This study analyzed a global dataset of particulate organic carbon (POC), particulate inorganic carbon (PIC), and biogenic silica (bSi) concentrations, revealing the dominance of small-sized particles in POC and PIC and the larger size fraction in bSi. The findings emphasize the importance of combining large volume pumps with sediment traps to capture the full range of particulate matter in future sampling campaigns.

Summary: This study investigates the biomimetic potential of using amorphous CaCO3 (ACC) to mimic crustacean exoskeletons and optimize their physical and chemical properties. The researchers prepared monodisperse ACC microspheres with high sphericity and hardness using the gas diffusion method in the presence of Mg2+. The stability of ACC was found to be affected by environmental conditions, but the microspheres showed high stability under ambient conditions. This research provides guidance for the preparation of ACC biomimetic composites and enhances the understanding of biomineralization mechanisms.

Summary: Understanding the formation and growth conditions of crystals in reverse osmosis membrane channels is important for controlling scaling and increasing recovery. Crystals form in dead areas and sediment on the membrane surface. This study investigated the adsorption of polymeric inhibitor molecules on crystal surfaces and the antiscalant behavior during nucleation and growth of crystals on the membrane surface. The results showed that the adsorption rate of antiscalants depends on the dosage values and the size and amount of crystals depend on the supersaturation value in the dead areas.

Summary: Oilfield scaling is a common problem in water-based oilfield production. Chemical inhibitors, such as phosphonate functional group, are used to combat and prevent scale deposition. A series of tetrakis(methylenephosphonic acid)s, named CX-T, showed excellent compatibility with calcium ions at normal scale inhibitor dosage levels. Crystal structures of calcium complexes with four tetrakis(methylenephosphonic acid)s were determined. The tetraphosphonates with ethylene and hexamethylene spacer groups performed best for calcite scaling, while those with ethylene and tetramethylene spacer groups were most effective for barite scaling.

Summary: Equipment scaling affects global industrial applications, leading to reduced production efficiency. Anti-scaling agents are commonly used, but the mechanisms of scale inhibition, especially the localization of scale inhibitors on deposits, are not well understood. This study focuses on the synthesis and investigation of a novel fluorescent antiscalant, ADMP-F, which effectively controls the precipitation of CaCO3 and CaSO4 in solution and provides valuable information on the interaction between scale inhibitors and deposits. ADMP-F was found to be more effective than other fluorescent antiscalants, suggesting its potential as a tracer for organophosphonate scale inhibitors.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This study presents a novel heterojunction structure (SrTiO3/CN-TAL10.0) for enhanced photocatalytic water splitting (PWS). The incorporation of thiophenedicarboxaldehyde (TAL) through copolymerization significantly improves the photocatalytic activity of carbon nitride (CN) while maintaining its photostability performance. The optimized composition allows efficient isolation of photoinduced charge carriers and enhanced charge transport, resulting in a remarkable increase in overall photocatalytic efficiency.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
