Abstract

The abuse of plastic food packaging has brought about severe white pollution issues around the world. Developing green and sustainable biomass packaging is an effective way to solve this problem. Hence, a chitosan/sodium alginate-based multilayer film is fabricated via a layer-by-layer (LBL) self-assembly method. With the help of superior interaction between the layers, the multilayer film possesses excellent mechanical properties (with a tensile strength of 50 MPa). Besides, the film displays outstanding water retention property (blocking moisture of 97.56%) and ultraviolet blocking property. Anthocyanin is introduced into the film to detect the food quality since it is one natural plant… More > Graphic Abstract

Abstract Potato propagation through tubers and seed is an inefficient way of propagation thus we propose an alternative method in this study which is in vitro propagation. Plantlets were raised from True Potato Seeds (TPS) in test tubes containing 10 mL of Murashige Skoog (MS) medium. Subculturing was done after every 21 days and after four subsequent subculturing, when there was an adequate quantity of stock material, uninodal cuttings of about 3–4 mm in length were prepared from in vitro proliferated potato plants by excising leaves of 1–2 mm on each side of the node. Prepared uninodal cuttings were cultured on… More >

Abstract Salt stress is one of the major limitations to modern agriculture that negatively influences plant growth and productivity. Salt tolerant cultivar can provide excellent solution to enhance stress tolerance with plant fitness to unfavorable environments. Therefore, this study was aimed to screen salt tolerant sorghum genotypes through evaluating of different morphological, biochemical, and physiological attributes in response to salinity stress. In this study, we have been evaluated total six sorghum genotypes including Hybrid sorgo, Debgiri, BD-703, BD-706, BD-707, and BD-725 under salt stress (12 dS m⁻¹ NaCl). The response variables included length and weight of root and shoot, root: shoot… More >

Abstract Mine grouting reinforcement and water plugging projects often require large amounts of grouting materials. To reduce the carbon emission of grouting material production, improve the utilization of solid waste from mining enterprises, and meet the needs of mine reinforcement and seepage control, a double-liquid grouting material containing a high admixture of coal gangue powder/bottom ash geopolymer was studied. The setting time, fluidity, bleeding rate, and mechanical properties of grouting materials were studied through laboratory tests, and SEM analyzed the microstructure of the materials. The results show that the total mixture of calcined gangue does not exceed 60%. And the proportion… More >

Abstract A dynamic triaxial instrument was used to study the effects of different concentrations of sodium chloride and stress amplitudes on the dynamic properties of an expansive soil under cyclic loading. In particular, four parameters were considered in such a parametric investigation, namely, hysteresis curve morphology characteristic non-closure degree ε_p, the ratio of the short and long axis α, the slope of the long axis k and the enclosed area S. The results show that with an increase in the sodium chloride concentration, the soil particle double electric layer becomes thinner, the distance between soil particles decreases, and the whole sample… More >

Abstract Sodium-alginate (SA) based nanofluids represent a new generation of fluids with improved performances in terms of heat transfer. This work examines the influence of the nanoparticle shape on a non–Newtonian viscoplastic Cu–nanofluid pertaining to this category. In particular, a stretching/shrinking sheet subjected to a transverse magnetic field is considered. The proposed Cu–nanofluid consists of four different nanoparticles having different shapes, namely bricks, cylinders, platelets, and blades dispersed in a mixture of sodium alginate with Prandtl number Pr = 6.45. Suitable similarity transformations are employed to reduce non–linear PDEs into a system of ODEs and these equations and related boundary conditions… More >

Abstract Sodium silicate modification can improve the overall performance of wood. The modification process has a great influence on the properties of modified wood. In this study, a new method was introduced to analyze the wood modification process, and the properties of modified wood were studied. Poplar wood was modified with sodium silicate by vacuum-pressure impregnation. After screening using single-factor experiments, an orthogonal experiment was carried out with solution concentration, impregnation time, impregnation pressure, and the cycle times as experimental factors. The modified poplar with the best properties was selected by fuzzy mathematics and characterized by SEM, FT-IR, XRD and TG.… More > Graphic Abstract

Abstract Houttuynia cordata Thunb (HCT) is a medicinal and edible herb that has beneficial effects on various diseases due to its diuretic, anti-inflammatory, anti-oxidative, anti-microbial, anti-viral, anti-cancer and anti-diabetic properties. Most reports of its anti-cancer activity were conducted in vitro, and its effects on cutaneous squamous cell carcinoma (SCC) have not been investigated yet. Using DMBA/TPA induced SCC mice model, we found that topical treatment by HCT, as well as its bioactive ingredient monomer, efficiently inhibited tumor growth. Mechanistically, tumor infiltrating CD⁴⁺ , Foxp³⁺ T regulatory cells (Tregs) were significantly reduced and CD⁸⁺ /Treg cells ratio was largely increased in tumors… More >

Abstract To enhance mechanical properties and improve flame retardancy and smoke suppression of fast-growing poplar wood in wood applications, the wood was impregnated and modified. An organic phenolic prepolymer and inorganic sodium silicate was used as contrasting impregnation modifiers and wood samples were impregnated by a bionic “respiration” method with alternating positive and negative pressure. The weight percentage gain, density increase ratio, mechanical properties (bending and compressive strength and hardness), and water absorption rate of inorganic and organic-impregnated modified poplar wood (IIMPW and OIMPW, respectively) were compared and these properties in IIMPW were found to be higher than those of OIMPW… More >

Abstract Plant-based concretes are produced from plant aggregates and a binder. Plant fibers are mainly composed of saccharides (sugars) and these sugars can decrease the concentration of Ca²⁺ ions in the cement pore solution and delay the formation of hydration products. To improve the interfacial bond between fibers and matrix a chemical treatment is widely used. This study investigates the effect of sodium hydroxide treatment on physical and hygroscopic properties of Typha aggregates. In particular, a 5% sodium hydroxide solution is used to treat these aggregates and their bulk and absolute densities, porosity, water content and water absorption are evaluated accordingly.… More > Graphic Abstract
