Protein structure prediction has long been available as an alternative to experimental structure determination, especially via homology modeling based on templates from related sequences. Recently, models based on distance restraints from coevolutionary analysis via machine learning to have significantly expanded the…
Diamond is the quintessential superhard material widely known for its stiff and brittle nature and large electronic band gap. In stark contrast to these established benchmarks, our first-principles studies unveil surprising intrinsic structural ductility and electronic conductivity in diamond under coexisting large sh…
Poly (lactic acid) (PLA)-based biocomposites containing flax fiber (FF) and basalt fiber (BF) both separately and together were prepared by melt blending method at the total constant ratio of 30 wt%. Mechanical properties, thermo-mechanical characteristics, thermal stability, flow behaviors, water uptake, and morpholo…
Poor control on the exfoliation of covalent organic frameworks (COFs) remains a disadvantage for their application as two-dimensional nanosheets. An equally important problem is the reversible control at the available surface charges on COFs. Herein, a strategy for the reversible exfoliation, re-stacking, and surface-…
Ineffective delivery of pesticides leads to multiple application cycles of active ingredients (AIs), resulting in increased cost while endangering the environment via soil, water, and air contamination. Herein, we present a facile approach for localized delivery of pesticides by coating seeds with electrospun cellulos…
The green synthesis of silver nanoparticles (SNPs) using plant extracts is an eco-friendly method. It is a single step and offers several advantages such as time reducing, cost-effective and environmental non-toxic. Silver nanoparticles are a type of Noble metal nanoparticles and it has tremendous applications in the…
Photoelectrochemical cells (PECs), which use semiconductor electrodes (photoelectrodes) to absorb solar energy and perform chemical reactions, constitute one of the most attractive strategies to produce chemical fuels using renewable energy sources. Oxide-based photoelectrodes specifically have been intensively invest…
We theoretically formulate and experimentally demonstrate an analytical formalism for designing printed circuit board (PCB) metagratings (MGs), exercising individual control over amplitude and phase of numerous diffracted modes, in both reflection and transmission. These sparse periodic arrangements of subwavelength p…
Abstract Miniaturized power supplies, such as microsupercapacitors, are highly demanded in micro-electro mechanical systems (MEMS) and micro portable microdevices due to their superior cyclability, high power density, and considerable energy. In this study, we utilize ZIF-8 derived carbon as a source of active materia…
Abstract Reported here for the first time is the alkaline periodate oxidation of lignocelluloses for the selective isolation of cellulose nanocrystals (CNCs). With the high concentrations as a potassium salt at pH 10, periodate ions predominantly exist as dimeric orthoperiodate ions (H2I2O104−). With reduced oxidizing…
A surface digging effect of supported Ni NPs on an amorphous N-doped carbon is described, during which the surface-loaded Ni NPs would etch and sink into the underneath carbon support to prevent sintering. This process is driven by the strong coordination interaction between the surface Ni atoms and N-rich defects. In…
Hyper-cross-linked polymers (HCPs), as one of the variety of microporous polymers with nanosized pores, have attracted a lot of interest in carbon dioxide adsorption and storage. A HCP adsorbent based on benzene and Friedel–Crafts reaction was synthesized for CO 2 adsorption. The response surface methodology is sugges…
Abstract In nature, cacti use conical spines with oriented microbarbs and hydrophilic trichomes as an effective fog harvesting system. However, the fabrication dilemma of complex cactus‐inspired conical spines with oriented microbarbs limits their applications. Here, a magnetorheological drawing lithography (MRDL) met…
In the present research, a multifunctional hierarchical reinforcement was prepared by chemical modification of carbon fibers (CFs) with halloysite nanotubes (HNTs) by the bridging diethylenetriaminepentaacetic acid (DTPA) for improving interfacial microstructures and properties of composites. Surface structures and gr…
Abstract Acrylonitrile-butadiene-styrene (ABS) copolymer was filled with perlite mineral (PER) at four different loading level of 2.5%, 5%, 10% and 15%. ABS/PER composites were produced using lab-scale micro-compounder followed by injection molding process. Mechanical, thermo-mechanical, melt-flow and morphological pr…
Abstract Natural fibers are widely used in the various lightweight and medium load applications due to their vital advantages. Cyperus pangorei is abundantly found on the river banks. The current study deals with the usage of Cyperus pangorei fibers that were retted using a manual retting process in the brake pad form…
Silver thin films were prepared by direct current (DC) magnetron sputtering technique in Ar/N2 atmosphere with various N2 volumetric ratios on Si substrates. Silver thin films prepared in pure Ar atmosphere show highly (111) preferred orientation. However, as the N2 content increases, Ag (111) preferred orientation ev…
Biological cells are able to generate intricate structures and respond to external stimuli, sculpting their membrane from within. Simplified biomimetic systems can aid in understanding the principles which govern these shape changes and elucidate the response of the cell membrane under strong deformations. Here, a com…
Abstract Optoelectronics based on metal halide perovskites (MHPs) have shown substantial promise, following more than a decade of research. For prime routes of commercialization such as tandem solar cells, optical modeling which requires accurate optical data for the materials utilized is essential for engineering dev…
Due to the porous characteristics of cement-based materials, they are often corroded by salt solutions, which results in decreased durability, especially against damage under freeze-thaw cycles (FTCs). Improving surface properties is an effective way to improve the durability of these materials. In this study, a hydro…
