Summary: The industrial application of plywood made from soybean meal-based adhesive (SMA) was enhanced by improving the wet shear strength and water resistance through microwave-chemical treatment. The wet shear strength of SMA was improved to 0.93 MPa by optimizing microwave conditions and using PEG-PEI treatment, which was 32.86% higher than the China National Standard. The modified mechanism was characterized using various techniques, showing that the formation of crosslinking improved the bonding performance and water resistance of SMA, providing favorable conditions for further application.

Summary: Lithium silicate-based CO2 sorbents were synthesized using steel metallurgical slags, with K2CO3 addition improving CO2 capture efficiency by facilitating CO2 diffusion. The best capture capacity value of 104 mg(CO2)/g(material) was achieved with 20 wt% K2CO3 at 600 degrees C. Thermal stability was excellent, with only a 10% reduction in CO2 capture capacity after 20 adsorption-desorption cycles using 20 vol% CO2.

Summary: In this study, a dual-active pharmaceutical ingredient, metforminium ibuprofenate (MtHIb), was prepared by chemical structural modification. The properties of MtHIb in the glassy state were investigated using experimental and computational methods. The results demonstrate that chemical structural modification can effectively control the secondary relaxations of amorphous pharmaceuticals, which is of great significance for understanding these materials.

Summary: This study investigates the use of waste glass in concrete mixes to achieve optimal performance. The results show that waste glass with lower water absorption can reduce drying shrinkage and increase the apparent density of the concrete. Additionally, when waste glass is incorporated up to 21%, the compressive strength of the concrete increases up to 400°C due to reduced pore pressure caused by low water absorption.

Summary: Poly(n-butyl acrylate) (PnBA) and silica nanoparticle composites were studied using various analytical techniques, revealing the presence of amorphous bulk and interfacial regions in the composites. The mobility of side chains at the interfaces differed from that in the bulk polymer, attributed to interactions between the carbonyl groups in PnBA and the silica surfaces. This indicated a closer proximity of PnBA main chains near interfaces with silicon oxide compared to those in the bulk polymer.

Summary: The polymer blend composites reinforced with hydroxyapatite nanoparticles showed enhanced mechanical properties, oil resistance, hardness, and AC conductivity. The addition of nanoparticles also decreased the diffusion rate of the blend composites with an anomalous trend in the diffusion mechanism. Among the blend composites, the sample with 7 phr of HA exhibited good oil and solvent resistance, increased AC conductivity, and improved mechanical properties.

Summary: MSWI ashes are byproducts of municipal solid waste incineration, which can either accelerate or retard cement hydration. A new parameter - Incineration Ash Coefficient (IAC) - correlates reasonably well with the 7-day compressive strength of mortars incorporating MSWI ashes, based on the ashes' elemental composition.

Summary: The powder X-ray diffraction (PXRD) and differential scanning calorimetry (DSC) were used to characterize the structure and detect phase transformations of polycrystalline (+)-decursinol. The crystal system of decursinol was determined to be orthorhombic with a space group P212121 using PXRD. DSC analysis showed two polymorphic phase transitions at approximately 64°C and 68°C, and a melting peak at an extrapolated onset temperature of approximately 177°C.

Summary: The food industry has been researching vegetable fats and oils with specific mechanical properties and lipidic composition to ensure healthy products for consumers. This study demonstrates that the regiosomerism of fatty acids within TriAcylGlycerols (TAG) moieties significantly affects their properties and human digestion. By manipulating the distribution of fatty acids in natural cocoa butter, the obtained vegetable fats show improved chemical-physical features. Experimental investigations including DSC, rheological testing, PXRD, and NMR spectroscopy were conducted to understand the factors responsible for these characteristics.

Summary: This study investigates the suitability of photosensitizer PN grafted with lipid chains to form nano assemblies or mixed lipid vesicles for photodynamic therapy. The results show that PN-C-18 conjugates can control the thermodynamic and structural properties of mixtures, leading to the disintegration of vesicles due to pi-pi interactions between PN molecules.

Summary: This study proposed a novel method for synthesizing flower-like vaterite calcium carbonate using nanobubble-containing ethanol and water mixed solution as the solvent and discussed the formation mechanism of vaterite with different shapes. The synthesized vaterite has significant practical interest in the integrated treatment of wastewater contaminated by heavy metals with effective Cd(II) removal, providing a promising field for studying heavy metal and pollutant adsorption in the liquid phase.

Summary: This study investigates the effects of particle shape on the collapse of granular columns using the discrete element method. The results show that particle shape has a significant impact on deposition morphology, energy evolution, and mechanical coordination number. Sphericity and angularity are identified as the most important macroscale factors, while roughness has a weaker microscale influence.
