The aim of this study was to evaluate the effect of rosin upon fixing boron in Styrax tonkinensis (Piere) wood treated with mixtures of 3% boric acid and 1% rosin sizing agent. After treatment, wood samples were also analyzed by scanning electron microscope observation and energy-dispersive X-ray spectroscopy (SEM-EDX). The results showed that all boron-rosin formulations impregnated Styrax ton...

Near edge x-ray absorption fine structure (NEXAFS) spectra at the boron K-edge were measured for aqueous boric acid, borate, and polyborate ions, using liquid microjet technology, and compared with simulated spectra calculated from first principles density functional theory in the excited electron and core hole (XCH) approximation. Thermal motion in both hydrated and isolated molecules was inco...

The paper is based on the development of a wood preservative without metal salts to be used in use classes 3 and 4 (EN 335), eco-friendly and harmless to humans and animals. Boric acid was used as a biocide, due to its effectiveness against fungi and insects. It is also known to be easily leached from wood exposed to weather action. Colloidal silica was therefore added in the formulations to gu...

The present study investigates the adsorption and dissociation reaction pathways of boric acid, B(OH)3, and the reaction kinetic descriptors on NiO(001) and ZrO2(1 ̅11) surfaces. Density functional theory is employed for ground-state calculations, while the nudged elastic band method is used for obtaining reaction barriers. Strong electron correlations in the case of NiO are included using the D...

In cable sheath applications, plasticizer migration is important as it causes reduction in mechanical properties, deterioration, and pollution transported environments. This study focuses on the effect of inorganic fillers diffusion plasticizers from plasticized-PVC films. Plastisols were prepared by mixing plasticizer, thermal stabilizers, (boric acid, boron clay, sintered calcined waste talc,...
