ABSTRAKBeton merupakan suatu material yang secara umum menjadi kebutuhan masyarakat terhadap fasilitas infrastruktur konstruksi yang semakin meningkat seiring dengan perkembangan zaman, oleh sebab itu pemilihan beton sebagai bahan baku utama konstruksi bangunan sangatlah penting. Beberapa hal yang perlu ditinjau dalam…
Abstract In this study, insulation material was developed using polylactic acid (PLA), which is one of the most widely‐used biodegradable polymers. The PLA was fabricated into a fiber mat shape using the electrospinning method, and NaCl salt was added to achieve thinner fiber diameter. This fiber‐based mat showed lowe…
This research is concerned with a new type of ferrocement characterized by its lower density and enhanced thermal insulation. Lightweight ferrocement plates have many advantages, low weight, low cost, thermal insulation, environmental conservation. This work contain two group experimental : first different of layer fe…
The cadmium sulphide (CdS) film is grown on cadmium telluride (CdTe) nanorods (NRs) arrays by different methods such as chemical bath deposition (CBD), magnetron sputtering (MS), and homogenous precipitation (HP) techniques. The impact of various deposition methods is explored in detail on the growth of CdTe/CdS compo…
Double perovskite Ba2FeNbO6 (BFN) powders were synthesized by molten salt method. The present work offers an effective approach to tuning the Eg of BFN powders, which find promising applications in the fields of photovoltaic and photocatalytic devices.
The article deals with the assessment problems of especially essential structures. Increased demands on prevention of emergency situations and minimizing the consequences in the event of their occurrence require constant determination of especially essential structures condition. Achieving the goal of reliability and…
Thermal switches are a type of heat control devices widely used in electronics, engineering machinery, and other applications. Electrostatically driven thermal switches (EDTS) have received wide attention due to their high specific mass density, precise control of heat flow, and flexibility. However, most of the actua…
Abstract Graphene oxide modified with long flexible hydrocarbon chains attracts increasing interest in toughing and stabilizing polymer nanocomposites. Herein, graphene oxide bearing with two types of long alkyl chains, namely 2-octyldodecylamine (swallow tail) and dodecylamine (linear), were prepared and introduced i…
Covalent organic frameworks (COFs) are a class of porous organic polymers with designable and predictable platform that may provide new opportunities to develop a metal-free in-situ prepared photocatalyst by condensation method.
Typically, the optical applications of silicon (Si) are limited to wavelengths below ∼1100 nm. However, there is significant research on Si surface modification, which tries to extend the optical properties of Si further into the infrared (IR) region. In this work, we present an ultra-wideband complementary metal–oxid…
The morphotropic phase boundary (MPB) plays an important role in ferroelectric materials. Typically, two phases coexist in materials near the MPB. Such materials usually exhibit large piezoelectricities, dielectricities, and actuation strains. In this work, we produce an MPB-like effect in hybrid electrically poled, m…
In the last century, polymers have dominated the materials market, and in the later part of the 20th century, the possibility to further improve their properties and expand their applications was explored by combining polymers with reinforcing elements [...]
A phantom material was prepared with different percentages of soy-lignin bonded with Rhizophora spp. particleboard and different coating materials, including epoxy resin, gloss wood finish, and a mixture of epoxy resin and gloss wood finish. A set of samples without coating was prepared for comparison. Each sample was…
Biochar is being reported now a-days to potentially reduce the bioavailability of arsenic (As). A pot culture and an in vitro incubation study was conducted to evaluate the efficacy of biochar produced from different sources (viz., cow dung, poultry manure and sewage sludge) at low temperature (250ºC) on the phytoavai…
Abstract Type III‐B rotaxane dendrimer is a member of the rotaxane dendrimer family, but it is defined as dendritic polyrotaxane, branched through rings. Such rotaxane dendrimers have been synthesized through versatile copper‐catalyzed azide‐alkyne cycloaddition reactions. In order to incorporate more functionalities…
V–4Cr–4Ti alloys exhibit important advantages as a candidate structural materials for fusion reactor first-walls and blanket applications. V–4Cr–4Ti alloys were prepared by direct electrochemical reduction of the solid mixture of V2O3, Cr2O3 and TiO2 in the molten CaCl2–NaCl eutectic at 1073 K. The influence of cell v…
Established the possibility of galvanochemical obtaining of a plating stronger than in case of chrome precipitation. Proposed precipitation of ternary alloy Co-Мо-W, which allows using the effect of synergism. Proposed and researched usage instead of sulphate-anhydride electrolyte – citrate-diphosphate and ammonia-cit…
The effect of ion bombardment on the electron work functions, Φ of pure Al and Zn was reported earlier. A simple model is suggested for those observations in the present Addendum. Radiation was thought to change the metals’ Wigner-Seitz radius, rs which is the main parameter of Φ. Now rs is evaluated through the weigh…
Cross-flow microfiltration, using a microporous membrane, is a well-established technique for wine clarification in oenology because of its cost-effectiveness and high-throughput. However, membrane fouling remains a significant issue for wine filtration in high-throughput systems. Herein, an approach for in situ real-…
In this work, we perform a comparative study of the magnetization behavior of four series of compounds R2Fe14B and their hydrides R2Fe14BH5.5, and the compositions (Nd0.5R0.5)2Fe14B and their hydrides (Nd0.5R0.5')2Fe14BH5.5with R and R' = Ho, Er, and Tm. The magnetization is measured in pulsed magnetic fields up to 58…
