Bacteria contamination in drinking water and medical products can cause severe health problems. However, currently available sterilization methods, mainly based on the size-exclusion mechanism, are typically slow and require the entire contaminated water to pass through the filter. Here, we present an electroresponsiv…
Anisotropic noble metal nanoparticles especially branched gold nanoparticles with a large absorption cross-section and high molar extinction coefficient have promising applications in biomedical field. However, sophisticated and cumbersome methodologies of synthesis along with toxic precursors pose serious concern for…
A universal methodology to efficiently improve the photocatalyst performance of semiconductors was developed by employing exfoliated RuO2 two-dimensional nanosheets as a conducting hybridization matrix. The hybridization with a RuO2 nanosheet is easily achieved by crystal growth or electrostatically derived anchoring…
The characterization of the strength and fracture toughness of three common structural fibres, E-glass, AS4 carbon and Kevlar KM2, is presented in this work. The notched specimens were prepared by means of selective carving of individual fibres by means of the focused ion beam. A straight-fronted edge notch was introd…
We investigate theoretically the magnetization dynamics in a skyrmion magnonic crystal. Collective excitations are studied in a chain of touching ferromagnetic nanodots in a skyrmion magnetic configuration. The determined dispersion relation of coupled skyrmions shows a periodic dependence on the wave vector, a charac…
A set of eight helical diamines were designed and synthesized to demonstrate their relevance as all-in-one materials for multifarious applications in organic light-emitting diodes (OLEDs), that is, as hole-transporting materials (HTMs), EMs, bifunctional hole transporting + emissive materials, and host materials. Azah…
Laser direct processing is a promising approach for future flexible electronics because it enables easy, rapid, scalable, and low-temperature fabrication without using expensive equipment and toxic material. However, its application for nanomaterials with high chemical susceptibility, such as representatively Cu, is l…
ZnO with a uniform and complete coating of reduced graphene oxide (RGO) was prepared by a facile and rapid reaction using a solution synthesis scheme. A synthetic route that ZnO was first grown in situ on the GO surface and then reduced by NaBH 4 was proposed, and an optimum coating structure was obtained by investiga…
A knotty issue concerning the poor mechanical properties exists in the porogen leaching approach to porous scaffolds, despite its advantage in tuning pore structure. To address this hurdle, solid state extrusion (SSE) combined with porogen leaching was utilized to engineer porous scaffolds of poly(lactic acid) (PLA).…
Employing the $GW$ method, we discuss the electronic and topological properties of ${\mathrm{Bi}}_{2}{\mathrm{Te}}_{3}$ and ${\mathrm{Sb}}_{2}{\mathrm{Te}}_{3}$ thin films consisting of one to six quintuple layers (QLs). Although both bulk materials are three-dimensional topological insulators, the two-dimensional top…
Tin dioxide (SnO2) as lithium-ion batteries (LIBs) anode has attracted numerous interests due to its huge Li(+) storage capacity. However, more than 300% volume variation of SnO2 during the charge/discharge process results in dramatic degradation of electrochemical performance and thus poor cyclic stability, which has…
A glyco-nanovesicle (Lac-SS-DCM) is self-assembled by a rationally designed amphiphilic lactose derivative ( 1 ), which features a surface lactose corona, a disulfide linkage, and an activatable DCM near-infrared (NIR) probe moiety. Taking advantage of the disulfide linkage, Lac-SS-DCM can be triggered to disassemble…
Recently, the newly emerged two-dimensional nanomaterials, layered transition metal dichalcogenide (e.g. MoS2) nanosheets, have drawn tremendous attentions due to their extraordinary electronic and optical properties, and MoS2 quantum dots (MoS2 QDs) with lateral sizes less than 10 nm have been found to be highly lumi…
Abstract In this work we study metamaterial-enhanced graphene photodetectors operating in the mid-IR to THz. The detector element consists of a graphene ribbon embedded within a dual-metal split ring resonator, which acts like a cavity to enhance the absorption of electromagnetic radiation by the graphene ribbon, whil…
In this review, thermosetting polymers derived from natural resources are highlighted for future generation with greater sustainability for different applications. Recently, agro-based polymer products are gained popularity since last two decades due to the depletion of fossil reserves and to protect the environment f…
The goal of this study was to fabricate an appropriate replacement for cadaveric corneas to overcome a shortage of cadaveric corneas for transplantation. In this study, we fabricated transparent ultrathin film scaffolds with nature-derived aloe vera (AV) gel and silk fibroin (SF) for corneal endothelial cells (CECs).…
Parylene is a Food and Drug Administration (FDA)-approved material which can be safely used within the human body and it is also offers chemically inert and flexible merits. Here, we present a flexible parylene-based organic resistive random access memory (RRAM) device suitable for wearable biomedical application. The…
Self-assembly is a fundamental concept and a powerful approach in molecular science. However, creating functional materials with the desired properties through self-assembly remains challenging. In this work, through a combination of experimental and computational approaches, the self-assembly of small amphiphilic den…
Abstract Chemical reactions involving noncovalent bond formation are discussed with regard to the equilibrium and nonequilibrium states: An equilibrium-to-equilibirum chemical reaction involves change of equilibrium states by changing the environment; a nonequilibrium-to-equilibrium reaction involves change of metasta…
Electronic structure calculations have become a powerful foundation for computational materials engineering. Four major factors have enabled this unprecedented evolution, namely (i) the development of density functional theory (DFT), (ii) the creation of highly efficient computer programs to solve the Kohn-Sham equati…
