Abstract Wood, recognized as a renewable and environmentally sustainable material, plays a crucial role as an alternative energy resource within the construction industry. However, it is highly susceptible to mold and decay fungi, which can lead to surface discoloration and potentially compromise the structural integrity of wood. The advancement of nanotechnology has introduced innovative strategies for wood protection, enhancing its performance while imparting additional properties. Various approaches including nanosized metals, polymer nanocomposite and coating treatments are actively being explored in this field. Furthermore, integrating bio-based materials with nanotechnology offers a green and sustainable method for wood More >

Abstract The work deals with cellulose paper filled with nanocellulose and SrAl₂O₄:Eu,Dy oxide phosphor. It was found that both nanocellulose and oxide improve the tensile strength of the composites obtained. The samples with the oxide demonstrate a long-lasting photoluminescence (PL) under sunlight and ultra-violet (UV) illumination. Room-temperature the PL spectra reveal a wide multicomponent band spreading over all the visible spectral regions. The short-wavelength part of the band is ascribed to the cellulose-related luminescence, while the long-wavelength PL component with maxima near 540 nm corresponds to the luminescence of the SrAl₂O₄:Eu,Dy phosphor. The dependency of the PL… More > Graphic Abstract

Abstract Oat husks, a byproduct of oat milling operations with limited economic value, present a promising feedstock for biorefinery processes due to their chemical composition. This study investigates the conversion of C5 carbohydrates in oat husks into furfural through hydrothermal pretreatment using various phosphate-based catalysts, including H₃PO₄, NH₄H₂PO₄, NaH₂PO₄, KH₂PO₄, K₂HPO₄ and K₃PO₄ as catalyst. The catalysts’ effectiveness in promoting furfural production was evaluated under identical hydrothermal conditions (treatment time for 60 min at a constant temperature of 170°C and a catalyst amount). Continuous water steam was used to strip furfural from the reaction zone and minimize its degradation.… More > Graphic Abstract

Abstract Natural rubber (NR) foams are widely used. However, further studies are required for preparing eco-friendly NR foam and determining the optimum physical properties appropriate for application. This study aims to create an NR foam from rubber reinforced with sugarcane bagasse ash (SCBA) and sodium alginate. The results showed that the SCBA was primarily composed of silica or silicon dioxide (87.52% by weight) and carbon (11.41% by weight). This study investigated the influence of the amount of sodium alginate (0–5 phr) used in the NR foam formation. The addition of SCBA on the NR foam affected More > Graphic Abstract

Abstract Furfurylation, a renowned chemical modification technique, uses furfuryl alcohol to enhance the properties of wood. This technology can be further refined by incorporating renewable tannins, which promote cross-linking with furfuryl alcohol. This study investigates the effects of furfurylation and tannin-modified furfurylation on the physical and mechanical properties of tropical Gmelina wood (Gmelina arborea Roxb.). Experiments involved impregnating Gmelina wood with aqueous solutions of furfuryl alcohol (FA) at 40% and 70% concentrations, as well as FA-tannin combinations (FA 40%-TA and FA 70%-TA), followed by polymerization at 103°C. The results demonstrated that both FA and FA-tannin treatments significantly… More > Graphic Abstract

Abstract In recent years, degradable materials to replace petroleum-based materials in preparing high-performance foams have received much research attention. Degradable polymer foaming mostly uses supercritical fluids, especially carbon dioxide (Sc-CO₂). The main reason is that the foams obtained by Sc-CO₂ foaming have excellent performance, and the foaming agent is green and pollution-free. In current research, Poly (butylene adipate-co-terephthalate) (PBAT), poly (lactic acid) (PLA), and other degradable polymers are generally used as the main foaming materials, but the foaming performance of these degradable polyesters is poor and requires modification. In this work, 10% PLA was added to PBAT to… More > Graphic Abstract

Abstract Herein, cure characteristics, morphology, and mechanical properties of natural rubber filled with activated carbon-based materials were investigated. Carbon-based materials were prepared from bagasse, coffee grounds and pineapple crowns by the pyrolysis method at temperatures in the range of 300°C. As-synthesized carbon materials were characterized by optical microscopy (OM), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR) to analyze size distribution, morphology, and functional groups, respectively. OM and SEM analysis revealed that particles, flakes, and a small quantity of fiber-like carbon were obtained using bagasse and pineapple crown as raw materials, while honeycomb-like carbon materials… More > Graphic Abstract

Abstract One of the most prevalent malignant tumors worldwide, stomach cancer still has a high incidence and fatality rate in China, and the number of young people developing early-onset gastric cancer is steadily increasing. The 5-year survival rate of stomach cancer is typically 30%–35%, the prognosis is bad, the patients’ quality of life is low, and the progression of advanced gastric cancer cannot be effectively managed despite the use of surgical surgery, chemotherapy, and other medicines. We urgently need molecular biomarkers with high specificity and sensitivity to increase the early gastric cancer detection rate, extend patient… More >

Abstract Objectives: Deubiquitinase OTUB2 plays a critical role in the progression of various tumors. However, its specific role in triple-negative breast cancer (TNBC) remains unclear. This study aims to elucidate the biological function of OTUB2 in TNBC and uncover the underlying mechanisms. Methods: First, we found that the expression of OTUB2 was upregulated in TNBC by bioinformatics analysis, we then validated its expression in TNBC tissues and cells using immunohistochemistry (IHC) and qPCR and plotted the survival curves by Kaplan-Meier method. Gene set enrichment analysis (GSEA) suggested that OTUB2 may be involved in tumor proliferation and metastasis.… More > Graphic Abstract
