The sub-nanocluster metal catalysts exhibit outstanding activities for a variety of catalytic reactions. Here, from density functional theory (DFT) simulations, we systematically explored the potential of an experimentally well-defined Au 22 (L 8 ) 6 nanocluster (where L 8 = 1,8-bis(diphenylphosphino)) as an electroca…
Abstract Phonons provide information on the physicochemical properties of a crystalline lattice from the material’s vibrational spectrum. Optical phonons, in particular, can be probed at both micrometre and nanometre scales using light-based techniques, such as, micro-Raman and tip-enhanced Raman spectroscopy (TERS),…
Access to standard form of energy in cooking and lighting has been a serious concern among most of the people residing in rural parts of the world. More than 2 billion people concentrated mostly in rural areas of India and sub-Saharan Africa use firewood in inefficient (thermal efficiency is <8–10%) traditional cook s…
A sol–gel process is used in this work to obtain porous materials with three-dimensional, chemically cross-linked solid networks from polyurea with their meso- and macropores filled with a liquid achieved via an oil-in-oil (O/O) emulsion. These materials are suitable for transport of nutrients with potential applicati…
Abstract Experimentally observed, stable trions with large binding energy (≈25 meV) in atomically thin monolayer 2D transition metal dichalcogenides MX2 (M = Mo, W, X = S, Se, and Te) with an isotropic crystal structure have been extensively studied. In contrast, the characteristics of trions in atomically thin 2D mat…
We report the viscoelastic relaxation mechanisms of cellulose nanocrystals (CNCs) dispersed individually in fluids. Linear viscoelasticity and flow birefringence of softwood and tunicate CNC/glycerol dispersions in the dilute regime were measured. The obtained results were then compared with molecular theories for the…
Understanding of ultrafast carrier dynamics in InP/ZnS colloidal quantum dots (QDs) is essential for their optoelectronic applications. In this paper, we have successfully fabricated high-quality InP/ZnS core–shell QDs with quantum yield (QY) of 47%. Time-resolved photoluminescence (TRPL) and femtosecond transient abs…
Abstract Supercapacitors are a promising energy storage technology owing to their unparalleled power and lifetime. However, to meet the continuously rising demands of energy storage, they must be equipped with higher energy densities. For this purpose, the seamless integration of metal oxides on carbon matrices, such…
Magnetoelectric spectroscopy is a powerful tool to determine all off-diagonal elements of the magnetoelectric tensor in a contactless fashion. Here, the authors demonstrate the efficiency of this optical method by measuring the off-diagonal magnetoelectric response of LiCoPO${}_{4}$ in the GHz-THz regime. They find th…
In this paper, we report the first successful demonstration of the direct growth of high-quality two-dimensional (2D) MoS2 semiconductors on a flexible substrate using a 25-μm-thick Yttria-stabilized zirconia ceramic substrate. Few-layered MoS2 crystals grown at 800 °C showed a uniform crystal size of approximately 50…
centers in a varity of diamond nanostructures and still maintaining the excellent optical coherence of these color centers.
PLGA-based nanoparticles are the most studied for cancer therapy. Insufficient stability and sustained drug release, however, often lead to reduced targetability and antitumor efficacy in vivo . In this work, we report on cRGD-installed reduction-responsive cross-linked nanotherapeutics based on a star PLGA-lipoic aci…
We reported the synthesis of graphenated-carbon nanotubes (G-CNTs) using a floating catalyst chemical vapour deposition (FCCVD) method and formed a bulk-cotton-like structure. The objectives of this work were to study the effect of the injection rate parameter of the carbon source on the formation of G-CNTs and CNTs a…
The accurate and precise quantification of the number of layers of MoS 2 nanosheets is highly desirable to accomplish the advanced optoelectronic device applications, which is a real challenge in cutting edge science. In recent years, multitudinous efforts have been put forward, but no certain protocol is available to…
Magnetization and magnetostriction are of critical importance to understand the magnetic behavior of ferromagnetic materials under stress and magnetic fields. The micromechanism of magnetization (or magnetostriction) is determined by the probability of angular distribution of magnetic moments and saturation magnetizat…
Abstract The implementation of photoswitches within polymers offers an exciting toolbox in the design of light‐responsive materials as irradiation can be controlled both spatially and temporally. Herein, we introduce a range of water‐soluble copolymers featuring naphthol‐based chromophores as photoacids in the side ch…
Abstract Biopolymer products are widely used in our everyday life, however, the poor antimicrobial nature dramatically limits their applications. Therefore, it is essential to improve the antibiotic performance of these biopolymer products. In this study, soy protein isolate (SPI)‐based films with antimicrobial and an…
The reactor is an extreme environment of high temperature, high pressure, and high radiation dose. Damage accumulates in structural materials over service time. It will eventually lead to material failure, such as hardening, embrittlement, and swelling. The radiation damage accumulation is an inherent, complex, and mu…
Shear-induced crystallization of dyes in the amorphous state is an effective strategy for generating higher energy emission after mechanical perturbation—a rare phenomenon in mechanoresponsive materials. Recently, we reported that a β-diketone with a 3,4,5-trimethoxy-substituted phenyl ring formed a stable supercooled…
Novel monolayer allotropes of As and Sb monolayers are predicted to be energetically and dynamically stable by calculations based on density functional theory. Remarkably, these monolayers possess superior mechanical flexibility and can withstand tensile strain as large as 58% in the armchair direction and 24% in the…
