Summary: Simulating the phenomenon of spinodal decomposition in glasses and polymers has become popular, but simulation models are affected by uncertainties. This study quantifies the consequences of such uncertainties in the phase separation modeling of Na2O-SiO2 glass and finds that thermodynamic quantities are less impacted by random perturbations than kinetic quantities.

Summary: This paper presents the results of a study on low CO2 cements made of limestone and portland cement modified with waste glass-based sodium silicate. The study found that the addition of waste glass-based sodium silicate had significant effects on various properties of the cement, such as setting time, heat released, flowability, and strength development. It was also discovered that low alkali content in the sodium silicate improved early strength without compromising late strength. The results suggest that this new type of cement has the potential to reduce CO2 emissions as a low carbon alternative.

Summary: This article evaluates the influence of Na2O concentration from sodium silicate and metasilicate activators on the physical, mechanical, and chemical/mineralogical properties of blast furnace slag alkali-activated mixtures. The results show that the optimal dosage of Na2O for achieving the highest compressive strength is 6% or 7.5% at 28 days, while the range of 4.5% to 6% is optimal for flexural strength. Excessive cracking is observed at the dosage of 7.5%, especially affecting the tensile strength. The sustainability assessment indicates that mixtures with 4.5% and 6% Na2O are more efficient in terms of CO2 emission efficiency and costs.

Summary: Phase formation in glasses from the Na2O-Y2O3-SiO2-ZrO2 system was studied and the effects of thermal history were investigated. During slow cooling, a precipitate of apatite structure phase (NaY9Si6O26) was observed, whereas the remaining glassy phase was enriched in ZrO2. It was also found that fast cooling resulted in glass formation without instant crystallization. Subsequent heating led to the formation of an unknown phase at lower temperatures and NaYSi2O6 crystals at higher temperatures. Nucleation and crystal growth experiments showed the homogeneous formation of small ZrO2 particles within the samples.

Summary: The impact of adding Eu2O3 and Nd2O3 on the crystallization behavior of NAS glasses was discussed, revealing that the addition of rare-earth oxides resulted in decreased crystallization activation energy and increased Avrami parameter n, indicating a tendency towards bulk crystallization and two dimensional crystal growth. As the heating temperature increased from 650 to 780 degrees Celsius, ZrO2, low-carnegieite, and nepheline crystals successively precipitated in NAS glasses, with Nd2O3 showing more effectiveness in promoting crystallization and forming ultra-fine microstructure compared to Eu2O3.

Summary: This study investigates the interaction between the zwitterionic surfactant CAPB and the polymer PAA, and its impact on the properties of their mixtures. The results show that phase separation occurs only when the PAA chain length is long enough, and the pH and polymerization degree also affect the phase separation. However, the ionic strength does not play a significant role in these phenomena.

Summary: Glasses in the Na2O-B2O3-SiO2-Fe2O3 system with compositions containing 7-12 mol % Fe2O3 and a constant SiO2 concentration of 70 mol % were studied at 550 degrees C. The immiscibility areas and crystallization fields of magnetite and FeSiO3 were outlined, with Fe3+ and Fe2+ ions found to be octahedrally coordinated in the low-alkali region and tetrahedrally and octahedrally coordinated in the higher alkali area. The formation of FeSiO3 in the low-alkali region was attributed to a significant amount of Fe2+.

Summary: PNIPAAM polymers have a lower critical solution temperature at 32 degrees C, which can be finely tuned by changing physical chemical parameters. Studies have shown that in the presence of NaCl, the radius of the polymer increases, while an increase in temperature causes polymer chain shrinkage, leading to aggregation at the LCST.

Summary: Amyloid proteins have both pathological and functional roles in diseases, and lipids have shown to strongly affect the formation and structure of these proteins. This study investigated how two lysolipids, LPG and 3-phosphocholine, impact the fibrillation of functional amyloid FapC. The results revealed that LPG promotes fibrillation at its critical micelle concentration by promoting the formation of large structures, while inhibiting fibrillation at concentrations above its cmc by locking FapC in a core-shell structure. On the other hand, 3-phosphocholine induces fibrillation at concentrations above its cmc by being incorporated during fibrillation and likely stabilizing the fibrillation nucleus. It was also found that LPG does not incorporate into the fibril during assembly, but can coat the final fibril. These findings highlight the importance of lipid concentration and composition in the fibrillation of functional amyloid.

Recent interest has focused on strategies to target amyloid formation and interrupt biofilm formation due to their antimicrobial potential. The interaction between the components FapA, FapB, and FapC is crucial for Fap fibril biogenesis, with FapA acting as a chaperone to prevent FapC fibrillation in the periplasm.

Summary: The effects of radiation on the aggregation of nanoplatelets of aluminum oxyhydroxide in nitrate slurries were studied using neutron scattering. Irradiated boehmite formed smaller primary aggregates with rougher surfaces compared to the pristine material, possibly due to breaking of surface species. Irradiated boehmite slurries had lower pH at low salt concentrations, indicating less proton adsorption or more hydroxide adsorption on the surface.

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.

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.
