Abstract The activation effect of boric acid as an activator is good, and we investigate the best activation conditions for the boric acid impregnation method. To represent the structural characteristics and adsorption performance of the Stellera Chamaejasme based carbon molecular sieves, we use Brunner-Emmet-Teller (BET) measurements, scanning electron microscope (SEM), Raman spectra (Raman), X-ray diffraction (XRD), and adsorption property measurement. When the loading ratio was 0.68:1, the specific surface area was 532.21 m²/g, the total pore volume was 0.24 cm³/g, the average pore size was 1.81 nm, the adsorption value of methylene blue was 145.28 mg/g, and the adsorption value of More >

Abstract The strict environmental regulations to overcome the drawbacks of consumption and disposal of non-renewable synthetic materials have motivated this investigation. The physical, chemical, morphological, and thermal properties of Hylocereus Polyrhizus peel (HPP) powder obtained from the raw materials were examined in this study. The physical properties analyzes of Hylocereus Polyrhizus peel (HPP) powder discovered that the moisture content, density, and water holding capacity were 9.70%, 0.45 g/cm3 , and 98.60%, respectively. Meanwhile, the chemical composition analysis of Hylocereus Polyrhizus peel (HPP) powder revealed that the powder was significantly high in cellulose contents (34.35%) from other bio-peel wastes.

Abstract The aim of this research work was to evaluate the potential of using renewable natural feedstock, i.e., Jatropha curcas oil (JCO) for the synthesis of non-isocyanate polyurethane (NIPU) resin for wood composite applications. Commercial polyurethane (PU) is synthesized through a polycondensation reaction between isocyanate and polyol. However, utilizing toxic and unsustainable isocyanates for obtaining PU could contribute to negative impacts on the environment and human health. Therefore, the development of PU from eco-friendly and sustainable resources without the isocyanate route is required. In this work, tetra-n-butyl ammonium bromide was used as the activator to open the… More > Graphic Abstract

Abstract In this work, a pure gum mould made of prevulcanized natural rubber/cloisite-Na⁺ nanocomposite (PVNR/CN) was prepared and characterized for ornament application. The suitable conditions to prepare PVNR/CN latex mixtures and the properties of the resulting PVNR/CN nanocomposites were investigated. The optimum CN concentration in the latex mixture was 1.0 phr, with the properties of 60 wt% total solid content, more than 600 sec mechanical stability time, lower than 350 cP Brookfield viscosity, and pH 10. The properties of PVNR/CN nanocomposite showed high strength, moderate hardness, and good thermal stability. The morphology by TEM showed well dispersion More >

Abstract Vibrational characteristics in small horizontal axis wind turbine system are presented in this study with a system concept called tactile response and substructuring. The main focus is on managing the dynamic properties like vibration, noise, and harshness that occur during the operational mode. Tactile response is defined as the response of subsystem which is induced when a human body touches a vibrating system. Sub structuring is a computational method used to reduce the dynamic behavior of a large complex system with a smaller number of degrees of freedom without disturbing the mesh size of the… More >

Abstract The characterization and functions of transmembrane protein 59-like (TMEM59L), a type I transmembrane protein, are not clearly understood until now. Some TMEM59L and fluorescent fusion proteins constructs were transfected in cell lines and liposomes, and their localization was observed. The effects of protein constructs were studied by fluorescence microscopy and western blotting. This study reports a novel function of human TMEM59L (hTMEM59L) related to the expression and location of some proteins. In addition, we report two novel splice variants of human TMEM59L (hTMEM59L). The localization of mutants of this protein, lacking a middle region, and… More >

Abstract The development of new architecture metallic alloys with controlled microstructures is one of the strategic ways for designing materials with high innovation potential and, particularly with improved mechanical properties as required for structural materials [1]. Indeed, unlike conventional counterparts, metallic materials having so-called harmonic structure displays strength and ductility synergy. The latter occurs due to a unique microstructure design: a coarse grain structure surrounded by a 3D continuous network of ultra-fine grain known as “core” and “shell”, respectively. In the present study, pure harmonic-structured (HS) Nickel samples were processed via controlled mechanical milling and followed… More >

Abstract Bamboo harvesting residues are wastes by-products of bamboo industries that contain holocellulose for about 63.14% to 70.71%, which often be discarded, incinerated or buried. In this study, carboxymethyl cellulose was prepared from bamboo harvesting residues (bamboo-branch and bamboo-tip) as raw materials. The chemical composition of bamboo harvesting residues, the viscosity and degree of substitution of carboxymethyl cellulose were determined. Carboxymethyl cellulose obtained was further characterized and compared by means of FTIR, SEM, XRD and TG. Results showed that under the optimized identical conditions, the viscosity and degree of substitution of carboxymethyl cellulose from bamboo-branch and More > Graphic Abstract

Abstract Lysin motif (LysM)-containing proteins (LYPs) are important pattern recognition receptors in plants. However, the evolutionary history and characteristics of LYP genes remain largely unclear in wheat. In this study, 62 LYPs were identified at genome wide in wheat. Based on phylogenetic and domain analysis, wheat LYPs were classified into 6 subgroups (group LysMe, LysMn, LYP, LYK, LysMFbox). Syntenic analysis showed the evolution of LYP genes in wheat. RNA-seq data showed that 22 genes were not expressed at any tissue or stress stimulation period. Some LYP and LYK genes were tissue- or stage- specific. The majority of TaLYK5s, More >

Abstract Leaf-color mutants play an important role in the study of chlorophyll metabolism, chloroplast development, and photosynthesis system. In this study, the yellow leaf 1 (yl1) rice mutant was identified from the ethyl methane sulfonate-treated mutant progeny of Lailong, a glutinous japonica rice landrace cultivated in Guizhou Province, China. Results showed that yl1 exhibited yellow leaves with decreased chlorophyll content throughout the growth period. Chloroplast development in the yl1 mutant was disrupted, and the grana lamellae was loosely packed and disordered. RNA sequencing and real-time quantitative polymerase chain reaction (qRT-PCR) analysis revealed that the chlorophyll synthesis-related genes OsCHLH, OsCHLM, OsCHLG, PORB,… More >
