Summary: This study examines the effect of random metal dilution on the thermal and structural properties of a spin-crossover single crystal. The research finds that at low dilution rates, the transition is of the first order, but increasing the concentration of dopants results in a decrease in cooperativity and gradual transformations. The study also observes significant changes in the organization of spin states during thermal transition, with a transition from single-domain nucleation to multi-droplet nucleation.

Summary: Efficient thermal management is crucial for maintaining energy balance and thermal comfort. The design of textiles that can regulate the infrared radiation emitted by the human body is appealing. By coating commercial woven fabrics with poly(N-isopropylacrylamide) hydrogels embedded with submicron-sized silica particles, the reflection of infrared radiation can be increased from 12% to 24% in the 5-15 μm wavelengths range. Further management of the silica particles allows reaching a reflection capacity of 36%. This research opens opportunities for energy-saving heating solutions in enclosed spaces.

Summary: This study investigates four different methods for seeding nanodiamond particles onto glass to produce nanocrystalline diamond coatings. These methods include standard spin coating, dip coating, ink-jet printing, and ultrasonic spray coating. The impact of these techniques on the properties of the diamond coatings, including morphology, optics, and mechanical performance, is studied. The droplet-based techniques show higher roughness but similar mechanical performance compared to spin coating.

Summary: Degradable magnesium (Mg) alloy with suitable biomechanical properties, good biocompatibility, and osteoconductivity is a potential material for orthopedic implants. However, its high corrosion rate in the human body limits its application. In this study, a polymeric layer of gelatin/nanohydroxyapatite (Gel/nHA) was coated on a ZK60 Mg alloy using dip coating and spin coating methods to improve corrosion resistance and biocompatibility. The results showed that both coating methods reduced the corrosion rate, with dip coating demonstrating better corrosion resistance.

Summary: This study discovered for the first time the significant differences in catalytic properties caused by different 'isotopic catalysts'. The commonly purchased Fe2O3 is a 'mixture' of different Fe isotopic oxides, meaning the catalytic effect of Fe2O3 is a synthesis of all isotopic compounds. The differences in catalytic properties of α-Fe2O3 with natural abundance ratio and separated isotopic α-Fe2O3 were investigated, and the results suggest that isotope effects are caused by nuclear morphology and charge distribution.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.

Summary: The power conversion efficiency (PCE) of organic solar cells (OSCs) has reached 20% in recent years, thanks to the advantages of organic photoactive materials. Benzothiadiazole (BT) has attracted significant research attention as a building block of OSCs. OSCs based on BT structure have shown diversity, and the increasing PCE values indicate a promising future for OSCs. This review analyzes the progress made in the last decades, focusing on effective BT small-molecules and BT polymers for OSCs. The structure-property relationships, donor-acceptor matching criteria, and morphology control approaches are discussed. The remaining challenges and a personal perspective on the future advancement of OSCs are summarized.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
