Summary: Melamine formaldehyde resin (MF) has limitations in industrial application due to its high cost, high content of free formaldehyde and susceptibility to cracking. Biomass modification of MF offers a solution to these problems. The synthesis of sucrose melamine-formaldehyde copolymer resin (SMF) using sucrose, melamine, and formaldehyde as raw materials under alkaline conditions was studied. The findings revealed that the sucrose content and curing agent had significant impacts on the thermal stability and curing behavior of SMF.

Summary: The effect of carbon black from Mao bamboo (MBCB) as a reinforcing agent in melamine urea formaldehyde (MUF) resin wood adhesive is evaluated. The incorporation of MBCB improves adhesion strength and reduces heat resistance and formaldehyde emission. However, the pre-pressing performance of the adhesive is reduced with higher substitution ratio. It is suggested that MBCB facilitates the curing reaction of MUF resin.

Summary: The addition of dispersed nano-SiO2 in a melamine/formaldehyde mixture improved the physical properties of a melamine formaldehyde resin. The incorporation of 0.42% eSiO(2) reduced the glass transition temperature of the resin and had minimal impact on its thermal stability. The modified resin showed different Raman spectra compared to the reference material, indicating changes in the hydroxymethyl and methylene bonds. These findings suggest that the addition of dispersed nano-SiO2 can enhance the toughness and other properties of the MF resin.

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: 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.
