Summary: In this study, expandable graphite was modified with zinc borate and the modified material, EGZB, showed smaller particle size, higher thermal stability, higher fire-extinguishing speed, and lower consumption than unmodified expandable graphite. The mechanism of fire extinguishing by EGZB was through capturing free radicals and strengthening covering and asphyxiation. This study provides crucial information for controlling fires caused by active metals and metallo-organic compounds.

Summary: In this study, a new type of composite fire-extinguishing powder was prepared and characterized for its morphology, structure, and thermal stability. The results showed that the powder had a smaller particle size and higher thermal stability compared to the unmodified counterpart. It was also found that the combination of sodium carbonate and expandable graphite had a synergistic effect on flame suppression and improved the fire-extinguishing efficiency.

Summary: The study evaluated the physical and mechanical properties of particleboard panels with different loading levels of nanocellulose and boric acid in the urea-formaldehyde resin. The results showed that adjusting the loading levels of NC and BA can enhance the performance properties of the panels, and using 3% NC and 3% BA provided the best results. The reinforcement techniques of NC and BA have the potential to develop novel furniture components and interior design materials.

Summary: In this study, a cement-based slurry was modified with polyvinyl alcohol and boric acid to improve its physical properties, chemical properties, and microstructure, in order to enhance the permeability resistance of rock grouting under high-water-pressure conditions. The modified slurry showed a shorter setting time and better crack resistance. The research findings confirmed the improved grouting effect and enhanced seepage resistance of the modified slurry through indoor tests, SEM testing, numerical calculation of the seepage field, and application in an actual project.

Summary: This study explores the outstanding dispersant and adhesive performances of cellulose to create a new effective fire-retardant: exfoliated and reassembled graphite (ERG). ERG, a 2D polyfunctional material, showed fast heat transfer away from flamed spots and underwent standard flame resistance tests reaching the highest possible class for combustible substrates, deriving its fire-retardant performance from thermal stability and heat transfer abilities. This new material may lead to a new class of flame-retardant coatings based on previously unexplored mechanism with several technical advantages.

Summary: The study focused on improving fire resistance of polyurethane foam by adding boric acid as a fire retardant. Different amounts of boric acid affected surface morphology and had an impact on density and compressive strength by altering the cell structure. Additional tests including X-ray diffraction, thermal analysis, and flame tests confirmed the effectiveness of boric acid as a fire retardant for PU with low toxicity combustion products.

Summary: In this study, raw AlN was modified with boric acid to enhance its hydrolysis resistance. The modified AlN powder showed no hydrolysis at high humidity and temperature, which was attributed to the formation of a protective layer on the surface of the crystal. This study provides an alternative method for preparing anti-hydrolysis AlN powders.

Summary: This investigation focuses on developing 'Reduced Emission Green Firecrackers' to minimize the negative impact of fireworks emissions. Two types of sound-emitting green firecrackers, Safe Minimal Aluminium Cracker and Safe Water Releaser, were developed using zeolite and boric acid hydrogel. The use of safer and inert additives resulted in significant reductions in particulate matter and gaseous emissions, without affecting the ignition temperature. The reduction in emissions was attributed to the dust suppressant, sorbent, and sequestering properties of zeolite, as well as the dust suppressant function of water released by boric acid hydrogel on ignition.

Summary: The paper introduces a performance-based framework to identify bridges at high fire risk, produce realistic fire scenarios, and provide guidance to improve fire resistance. By implementing this framework, the fire risk of bridges can be estimated and suitable fire protection measures can be determined to enhance their fire resistance.
