Abstract Coronaviruses are responsible for a developing budgetary, human and
fatality trouble, as the causative factor of infections, for example, severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2). It has been well recognized
that SARS-CoV-2 may survive under severe atmosphere circumstances. Hence,
efficient containment approaches, for example, sanitizing, are crucial. Commonly,
living compounds contribute a substance of chemical heterogeneity, with antiviral
movement, and therefore can have efficacy as therapeutic tools toward coronavirus diseases. Here, in this review article, we have described the antimicrobialbased materials, which can be used to inhibit the spreading of the COVID-19.
We have categorized these materials in three… More >

Abstract Locust bean gum (LBG) is a typical galactomannan isolated from carob
bean (Ceratonia siliqua L.) cultivated in the Mediterranean area. Due to its superior biodegradable, rheological and film-forming properties, LBG has been used
alone or combined with other biopolymers (e.g., polysaccharides, proteins and
lipids) to develop films. Till now, different kinds of functional ingredients (e.g.,
montmorillonite, bacteriocins, antibiotics, plant extract, essential oils and microbial cells) have been added into LBG-based films. Notably, the physical and functional properties of LBG-based films are affected by many factors, such as the
structure of LBG, the type and content of other biopolymers and functional… More >

Abstract Microbial fuel cells (MFCs) are an attractive innovation at the nexus of
energy and water security for the future. MFC utilizes electrochemically active
microorganisms to oxidize biodegradable substrates and generate bioelectricity
in a single step. The material of the anode plays a vital role in increasing the
MFC’s power output. The anode in MFC can be upgraded using nanomaterials
providing benefits of exceptional physicochemical properties. The nanomaterials
in anode gives a high surface area, improved electron transfer promotes electroactive biofilm. Enhanced power output in terms of Direct current (DC) can be
obtained as the consequence of improved microbe-electrode interaction. However,… More >

Abstract In this study, pre-concentrated bark, furfuryl alcohol and other biomass
raw materials were used to prepare foaming materials by high-speed mechanical
stirring without using a foaming agent. We investigated the effect of the postadded water amount on the properties of foaming materials. In particular, we
determined basic physical properties of these materials, including the limiting
oxygen index (LOI), porosity, thermal conductivity, thermogravimetric analysis,
pore size distribution, and microstructure. The results of scanning electron microscopy (SEM) indicated that the pore size distribution was uniform and the pore
size increased with increasing water volume. Thermogravimetric analysis (TG/
DTG) showed that when the… More >

Abstract The aim of this study is to explore the heterogeneous ice nucleation
behavior based on controllable micro-cubic array structure surfaces from the statistic perspective. To this end, we firstly constructed a group of micro-cubic array
structures on silicon substrates by a selective plasma etching technique. After
grafting low-free-energy substance, the as-constructed micro-cubic array structure
surfaces exhibited higher non-wettability with the water contact angle being up to
150°. On this basis, 500 cycles of freezing and melting processes were accurately
recorded to analyze the instantaneous ice nucleation behavior according to the statistical results of freezing temperature. As a consequence, the statistical… More >

Abstract In this work, Epoxidized natural rubber/sawdust short fiber (ENR-50/
SD) composites at different fiber content (5, 10, 15 and 20 phr) and size (fine size
at 60–100 μm and coarse size at 10–20 mm) were prepared using two-roll mill
and electrical-hydraulic hot press machine respectively. Curing characteristics,
water uptake, tensile, morphological, physical, and thermal properties of the composites were investigated. Results indicated that the scorch time and cure time
became shorter whereas torque improved as SD content increase. Though the
decline of tensile strength and elongation at break values, modulus, hardness
and crosslinking density have shown enhancements with the increasing… More >

Abstract In order to increase use ratio of steel slag solid waste, the concrete containing steel slag powder and zeolite powder as admixtures was prepared by using
the orthogonal test method. The effects of water-binder ratio, sand ratio, steel slag
powder content and zeolite powder on working properties, mechanical strength
and chloride ion permeability of the concrete was studied. It was found that the
early strength of the concrete had a decrease with the mixing of steel slag and zeolite powders, but its later strength approached to pure concrete. Moreover, the
physical filling and pozzolanic activity of the admixtures increased the… More >

Abstract In this study, the feasibility of producing eco-friendly bricks by using
geopolymer technology and a waste grinding wheel (WGW) from the grinding
wheel industries was investigated. Nowadays, in order to meet industrial needs,
for instance, in Taiwan, approximately 500,000 grinding wheels are used
annually. That is, a large number of “waste” grinding wheels are produced.
Furthermore, few studies have been conducted on the use of WGWs as raw materials in geopolymer applications. The use of geopolymer technology to form
bricks can avoid the utilization of clay and cement and even prevent the use of
a high-temperature process in kilns. Moreover,… More >

Abstract Polylactic acid (PLA) bioplastic is a common material used in Fused
Deposition Modeling (FDM) 3D printing. It is biodegradable and environmentally
friendly biopolymer which made out of corn. However, it exhibits weak mechanical properties which reduced its usability as a functional prototype in a real-world
application. In the present study, two PLA composites are created through coextruded with 3K carbon fibres and twisted Kevlar string (as core fibre) to form a
fibre reinforced parts (FRP). The mechanical strength of printed parts was examined using ASTM D638 standard with a strain rate of 1 mm/min. It has been
demonstrated that the… More >

Abstract Based on the LOM (Laminated Object Manufacturing) process, an inert
gas-assisted laser method for wood cutting was proposed. The carbonization degree
of wood surface was improved by the introduction of helium (He) gas, and the influence of process parameters on the carbonization layer of wood surface was solved, it
was significance to reduce the post-processing of LOM and improve the quality of
forming workpiece. The cherry wood veneer was used as the experimental material,
under the condition of the same process parameters, the wood was cut with or without
inert gas-assisted, and the influence factors of kerf quality were studied… More >
