Abstract Semi-transparent perovskite solar cells (ST-PSCs) are promising in building-integrated photovoltaics (BIPVs) and tandem solar cells (TSCs). One of the keys to fabricate high-performance ST-PSCs is depositing efficient transparent electrodes. Indium tin oxide (ITO) is an excellent transparent conductive oxide with good light transmittance and high conductivity. However, the high sheet resistance of ITO sputtered at room temperature leads to the low fill factor (FF) and poor power conversion efficiency (PCE) of the ST-PSCs. Here, we study the effect of the sputtering temperature on the properties of ITO and the performance of ST-PSCs. We find that when the sputtering temperature increases… More >

Abstract Traditional formaldehyde-based adhesives rely excessively on petrochemical resources, release toxic gases, and pollute the environment. Plant-derived soybean protein adhesives are eco-friendly materials that have the potential to replace the formaldehyde-based adhesives used to fabricate wood-based panels. However, the poor water resistance, high brittleness, and poor mildew resistance of soybean protein adhesives limit their industrial applications. This article reviews recent research progress in the modification of soybean protein adhesives for improving the bonding performance of adhesives used for wood-based panel fabrication. Modification methods were summarized in terms of water resistance, solid content, and mildew resistance. The modification mechanisms and remaining problems… More >

Abstract The present study was conducted to evaluate the impact of bimetallic nanoparticles (NPs) of copper (Cu) and zinc (Zn) from Crotalaria longirostrata on the insect mortality and cell viability of Phenacoccus solenopsis. The biosynthesis of bimetallic nanoparticles (Cu/Zn-NPs) from C. longirostrata was confirmed by the presence of a single peak around 378 nm. The hydrodynamic diameter of the Cu/Zn nanoparticles varied from 59 to 119 nm and their zeta potential was found to be −30.90 mV. The EDX analysis showed a strong signal for Cu and Zn (8 and 8.6 keV, respectively). The Cu/Zn-NPs showed an effective insecticide activity against P. solenopsis with 63%… More >

Abstract DFT and TD-DFT calculations of HOMO and LUMO energies and photovoltaic properties are carried out on four selected pentathiophene donor and one IDIC-4F acceptor molecules using B3LYP and PBE0 functionals for the ground state energy calculations and CAM-B3LYP functional for the excited state calculations. The discrepancy between the calculated and experimental energies is reduced by correlating them with a linear fit. The fitted energies of HOMO and LUMO are used to calculate the Voc of an OSC based on these donors and acceptor blend and compared with experimental values. Using the Scharber model the calculated PCE of the donor-acceptor molecules… More >

Abstract Phenolic compounds are related to high biological activity, avoiding oxidation in food and human systems. Nutshells are by-products derived from the pecan nut processing that contain important amounts of phenols which biological activity must be studied. This research aimed to evaluate the antioxidant (DPPH, ABTS, FRAP and hemolysis) and anti-inflammatory activities of shell extracts from pecan nuts harvested during the crop production cycle 2018 and 2019, as well as the in vitro digestibility of their phenolic compounds, including flavonoids. Results showed that extracts from the crop production cycle 2018 obtained the highest yield, while those from 2019 contained the highest… More >

Abstract This study investigated the mechanical properties and microstructural characteristics of fiberboard composite produced by naturally-bonded Malaysian bamboo fiber (Bambusa vulgaris). The components that obtained through soda pulping of bamboo culms such as fiber and black liquor, were used for the preparation of high-density fibreboard composite at two target densities of 850 and 950 kg/m3. The bamboo fiberboard composite (BFC) were then produced at 200°C and two pressing parameters of 125 and 175 s/mm. The mechanical properties, e.g., flexural strength and internal bonding (IB) of BFC samples were evaluated according to BS EN 310: 1993 and BS EN 319: 1993, respectively. It was… More >

Abstract The exploitation of biomass represents a major environmental challenge related to the protection of the environment and the progressive exhaust of fossil resources. In this perspective, the main objective of this work is the extraction and the characterization of natural lignocellulosic fibers from the Schinus molle. The cellulose fibre extraction was investigated employing conditions of alkali treatment. After the alkaline steps, a bleaching treatment was done and let to a yield about 45% pure cellulose. The identification of the chemical composition of Schinus molle reveals that this raw material contains a high level of biopolymers with a cellulose rate of… More >

Abstract With the growing level of awareness and increasing demand for environmental protection, timber pile revetments
with significant ecological effects have experienced increasingly wide application in China. The current timber pile
revetment system has two problems: continuous dense piles have high construction costs and require large timber
consumptions, while the discrete pile-bamboo fence systems have poor retaining effects. Considering these problems, an original revetment structure form is proposed: a discrete pile-mulberry straw arch structure. To investigate the mechanical properties of the mulberry straw, some mechanical tests are conducted on mulberry straw
and its arch structure. It is found that the average… More >

Abstract The emission of greenhouse gases from cement production is an obstacle for sustainable development of construction industry. The use of waste materials in constructions instead of cement could be a feasible solution
to green construction. Waste marble powder with good cementing property can be used in concrete partially
replace cement. In this research, the effects of using waste marble powder on the physical and mechanical properties of concrete have been studied. Three groups of particle size and five levels of replacement ratio (5%, 10%,
15%, 20%, 25%) for each group have been designed. During the different stage of hydration process,… More >

Abstract In this work, a bio-based flame retardant (Cy-HEDP) was synthesized from cytosine and HEDP through a facile
salt-forming reaction and embedded into epoxy matrix to improve the flame retardancy and smoke suppression
performance. The product Cy-HEDP was well characterized by FTIR, 1
H and 31P NMR and SEM tests. On the basis
of the results, by adding 15 wt% Cy-HEDP, the EP15 can pass UL-94 V-0 rating, and the total smoke production
(TSP) as well as total heat release (THR) can be decreased by 61.05% (from 22.61 to 8.7 m2

Abstract Nail joints are one of the key components that control the lateral performance of light wood frame shear walls. In previous experimental studies, researchers have used different loading rates, which failed specimens from less than a minute to more than an hour, to study the characteristics of nail joints. Moreover, there have been different loading protocols used for testing of timber nail joints or shear walls. Although some efforts have been made to address this subject, it is still unclear how the loading protocol and loading rate may influence the performance of nail joints. In this study, a total of… More >

Abstract In order to study the modification effect of recycled sand on cement reinforced waste slurry (CWS), triaxial test,
scanning electron microscope test and X-ray diffraction test were carried out. The mechanical test of recycled
sand and cement reinforced waste slurry (RCWS) shows that the deviatoric stress–strain curve of RCWS samples
changes from hardening type to softening type with the increase of recycled sand content; the peak stress
increases with the increase of recycled sand content; recycled sand can enhance the shear strength of CWS by
increasing both cohesion and internal friction angle. The microscopic test shows that recycled sand can… More >

Abstract Due to the existence of the attached mortar, the performance of the recycled concrete aggregate (RCA) is inferior
to the natural aggregate, which significantly limits its wide application in industry. In this study, five kinds of
modified solutions were used to modify the surface of RCA, and the modification effects were compared. The
results showed that sodium silicate, nano-silica (NS), Bacillus pasteurii and soybean powder had relatively good
modification effects on RCA, which could reduce the crushing value and water absorption, and increase apparent
density. The composite solution (15% sodium silicate and 2% NS) and soybean powder solution had better… More >
