Summary: Boric acid is the main form of boron in plasma and plays a role in physiological mechanisms such as cell replication. Both high doses of boron and its deficiency can have toxic effects. However, the cytotoxicity of pharmacological concentrations of boric acid on cancer cells has conflicting results. This review aims to summarize the main findings regarding boric acid uptake, actions, and effects on cancer cells.

Summary: In this study, the underwater dehydration of statistical copolymers synthesized from triethanolamine borate (TEAB) methacrylate and styrene (St) was reported as a new example of intrinsically water-triggered phenomena. The hydration of the copolymers became unfavorable through the hydrolysis of the pendant TEAB group, resulting in a novel concept for designing water-responsive materials.

Summary: This article provides a critical review of the molecular mechanisms involved in boron transport under limited and excess boron conditions. It focuses on various boron transport proteins and their regulation, mainly in Arabidopsis thaliana, and summarizes research progress in other crop plants. Understanding the complex regulatory mechanisms of boron transport can help develop high-yielding plants under fluctuating boron conditions.

Summary: The synthesis of cellulose acrylate from cellulose with acryloyl chloride is challenging due to unexpected gelation. However, the use of bulky amines is found crucial for reproducibility. The solubility of cellulose acrylate depends on reaction conditions due to possible cross-linking oxa-Michael reaction. Cellulose acrylate is a useful precursor for chemically modified cellulose materials and can react with various functionalized nucleophiles. This method is applied for the synthesis of N-methyl-d-glucamine-modified cellulose as a water adsorbent for B(OH)(3) removal.

Summary: The study found that supplementation of 3.6 g/d boron acid (equivalent to 200 ppm B) in the diet of growing animals has a positive effect on bone health-related biomarkers (OCN, NTx and BALP), while supplementation of the supranutritional level of 10.8 g (equivalent to 600 ppm B) had neither additional beneficial nor harmful effects on the bone health of calves.

Summary: Previous research has shown that graphene-coated ammonium perchlorate (AP) accelerates its decomposition kinetics, while hBN coating does not have a similar effect. Structural characterization including electron microscopy and X-ray diffraction were used to analyze the effects of AP crystal size and crystallinity. The accelerated decomposition kinetics of graphene-coated AP were quantified through thermogravimetric analysis, gas chromatography mass spectrometry, and kinetic modeling.

Summary: The expansion of sugarcane areas has led to increased peanut production in soils with low boron content. This study aimed to monitor the efficiency of boron application on peanut yield parameters, determine the optimal boron rate and source, and investigate boron leaching in tropical soils. The results showed that boron application significantly increased peanut yield, and the combination of soil and foliar application had the best effect.

Summary: A kinetic model for urea decomposition and byproduct formation was developed and validated against thermogravimetric analyses. The study found that an increase in heating rate leads to a shift in byproduct formation and a longer reaction time is necessary for complete urea decomposition at temperatures corresponding to SCR applications.

Summary: This study investigated the use of boron-based materials on efficiency of environmentally friendly porous ceramics. A glaze formulation was created using high amounts of frit and low-temperature sintering. Boric acid and colemanite were added to the glaze, and different formulations were created by reducing the frit percentage. X-ray crystallography analysis revealed the crystal phase structures of glaze samples, while scanning electron microscopy was used to examine the surface properties of the samples. Differential thermal analysis and thermogravimetric analysis were performed to determine their thermal behavior. The results showed that boron derivatives act as a good flux agent without negatively affecting the surface and technical properties of the glaze.

Summary: Different catalysts were used for the decomposition of AdBlue, with gamma-Al(2)O(3) identified as the best catalyst for promoting urea decomposition. Gaseous products including water, ammonia, CHNO, and CO₂ were detected at different reaction stages using mass spectrometry. The calculated activation energies for three stages were determined to be within specific ranges using the Kissinger-Akahira-Sunoe method.

Summary: The thermodynamics of allotropic transformation in nanocrystalline Fe was studied using molecular dynamics simulation and computational methods to determine Gibbs free energy parameters. The results showed that the allotropic transformation temperature of iron nanocrystal decreases from 900 K to 300 K as the grain size increases.

Summary: The study aimed to synthesize and characterize carbon/carbon composites using the CVI process, finding that increasing the process time led to changes in the density, specific surface area, thermal conductivity coefficient, and bending strength of the samples. The SEM images of the fracture surface indicated a weak interface between the carbon fibers and the carbon layer, with the morphology of carbon growth transitioning from laminar to rough-laminar with longer CVI process duration.

Summary: This research used numerical simulations to investigate the impact of structural parameters on fluid flow in metallic foams, finding that porosity variations greatly affect fluid flow while changes in pore diameter do not have a significant effect. The pressure gradient decreases as foam size increases, reaching a specific value and then remaining constant, with porosity variations having no effect on this length but pore diameter changes having a significant impact. A correlation was established to improve the Ergun equation for studying and predicting air flow on a large scale in practical engineering problems.
