Abstract Gold(I) N‐heterocyclic carbene (AuI‐NHC) complexes have emerged as potential anticancer agents owing to their high cytotoxicity and stability. Integration of their above unique functions with customized aggregation‐induced emission (AIE) luminogens to achieve specific bioimaging and efficient theranostics to…
Abstract We have synthesized CaKFe 4 As 4 single crystals by a simple one-step method. X-ray analysis suggests that the single crystals are c -axis orientation and no obvious impurity phase can be detected. The onset transition temperature is about 35 K with the Δ T c ∼ 1 K. By measuring the magnetoreistance, the vort…
Conventional approaches to the determination of the two-photon absorption cross-section (TPACS) of fluorescent semiconductor nanocrystals, including quantum dots (QDs) and nanoplatelets (NPLs), cannot be applied to samples with unknown concentrations and low optical densities and may be inaccurate in the case of multi…
This work has focused on in-situ crosslinking of gelatin (G) to produce electrospun scaffold with improved fiber morphology retention and mechanical properties. As per this approach, we prepared G nanofibers through mixing G, 1-ethyl-3-(3 dimethylaminopropyl) carbodiimide hydrochloride (EDC) and N-hydroxysuccinimide (…
The fabrication of flexible supercapacitors was achieved by employing the novel redox-activated polymer electrolytes comprising poly(vinylphosphonic acid) (PVPA) and nickel nitrate Ni(NO3)2, Ni. The hydrogels, PVPA/NiX, were produced in various contents, in which X denotes the doping fraction of Ni in PVPA. The struct…
Today's electronics cannot perform in harsh environments (e.g., elevated temperatures and ionizing radiation environments) found in many engineering applications. Based on the coupling between near-field thermal radiation and MEMS thermal actuation, we presented the design and modeling of NanoThermoMechanical AND, OR,…
Zwitterionic polymers are a distinctive class of materials with unique physical and chemical properties. In this study, the synthesis of fully zwitterionic ABA triblock copolymers was achieved by controlled radical polymerization using two different zwitterionic monomers, sulfobetaine methacrylate (SBMA) and 2-methacr…
In searching for new functional self-assembling materials a multicomponent ferroelectric liquid crystalline mixtures with features appropriate for utilization in photonic and electro-optic devices have been designed. Designed mixtures are composed of bicyclic pyrimidine achiral compounds and chiral dopants with an oli…
The light-stimulated transformation of ensembles of spherical nanoparticles into anisotropic metal nanostructures mediated by localized surface plasmon resonance (LSPR) excitation is an elegant way of synthesizing triangular silver nanoprisms with extraordinary control over size and shape. Generally, the transformatio…
Abstract Plasmonic metasurfaces act as appealing platforms for flexible and accurate wave regulation, but their functionalities in wavefront or spectral tuning are settled upon manufactured. So the ability to dynamically tailor the amplitude, phase or polarization is highly desirable for many scenarios of micro & nano…
Two-dimensional (2D) transition-metal dichalcogenide (TMD) materials have aroused noticeable interest due to their distinguished electronic and optical properties. However, little is known about their complex exciton properties together with the exciton dynamics process which have been expected to influence the perfor…
A new, transformative methodology for the preparation of diketopyrrolopyrroles from aldehydes, primary amines, nitriles, and diethyl oxalacetate has been developed. It is now possible to prepare diketopyrrolopyrroles bearing an ordered arrangement of three different substituents from abundant and commercially availabl…
The interaction of hydrogen (H) with dislocations in tungsten (W) must be understood in order to model the mechanical response of future plasma-facing materials for fusion applications. Here, hybrid quantum mechanics/molecular mechanics (QM/MM) simulations are employed to study the $\ensuremath{\langle}111\ensuremath{…
With the goal of improving performance of a hydrogen-rich storage medium, the influence of a collection of first and second period transition metal fluorides on the destabilization of NaBH4 is studied on samples produced by ball milling NaBH4 with 2 mol% of a metal fluoride additive. The effects obtained by increasing…
Abstract Semiconductors have numerous applications in both science and technology. Several methods have been developed to engineer their band gap, which is one of the most important parameters of semiconductors. Here, it is shown that the incorporation of various amino acids into the crystal lattice of copper (I) oxid…
The development of a strategy for the assembly of nanoscale building blocks, in particular, anisotropic nanoparticles, into desired structures is important for the construction of functional materials and devices. However, control over the orientation of rod-shaped nanoparticles on a substrate for integration into sol…
CdSe/CdS core-shell quantum rods (QRs) are a promising prospect in optoelectronic applications but usually have a relatively low quantum efficiency and stability. Here, we report on an efficient and stable CdSe/CdS/ZnS QRs-in-matrix assembly (QRAs) by growing and embedding CdSe/CdS QRs in ZnS matrices. Structural char…
Abstract Effect of anodization on the thermal performance of naturally cooled heat sinks in power electronic devices made of die-cast aluminum alloy A380 and machined aluminum alloy 6061 was investigated experimentally and numerically. Various types of anodization were examined with different thickness of anodic alumi…
Cellulose–silk fibroin (CSF) films were prepared by blending cellulose and silk fibroin (SF) in different ratios (10:0, 10:3, 10:6, 10:9, and 10:12 wt%) in 60% LiBr aqueous solution. All of the blend films were transparent, and their coloration gradually increased with increasing SF content. Interestingly, cross-secti…
Copper(II) oxide (CuO) nanoparticles (NPs) were synthesized by the calcination of a mixture of copper acetate and orange peel powder at 600 °C for 4 h. The average crystallite size and structure of the prepared sample was predicted by X-ray diffraction (XRD) analysis. Optical property of the sample was measured by usi…
