Abstract Stimuli‐responsive energy storage devices have attracted significant interest for their potential in next‐generation smart devices. Herein, the reversible photo‐switchable supercapacitors utilizing azobenzene‐containing polymer composite electrolytes are presented. Through gel‐to‐sol transition triggered by light exposure, as proven using rheological analysis, these exhibit an impressive ionic conductivity modulation of 3206%. Owing to photo‐responsive physical properties, deliver a...
Pressing environmental challenges require focused research on sustainable solutions in the domains of energy, water, food, land, and climate. The pigment eumelanin has recently been positioned as a promising candidate for solving issues health, sensors, energy storage. However, low solubility aqueous solvents, difficult film processibility, high cost have hindered material from wide deployment. Here, we propose melanin extracted black soldier fly, Hermetia illucens (Mel-BSF), alternative...
Gas-solid triboelectric nanogenerators (GS-TENGs) based on porous elastomers provide a promising avenue for the design of self-powered sensors. However, intrinsic limitation low electric output in GS-TENGs could affect accuracy and sensitivity sensing systems. Here, we develop composite by integrating an adhesive poly(siloxane-diphenylglyoxime-urethane) (PSDU) elastomer with ferroelectric (3,3-difluorocyclobutylammonium) 2 CuCl 4 [(DF-CBA) ] fillers. PSDU, intrinsically negative material...
Abstract The integration of electronics with the human body or wearables necessitates evolution energy storage devices capable seamless adaptation to conformability skin and textiles. This work focuses on developing an intrinsically stretchable electrode prepared by sedimenting liquid metal particles in a conductive matrix. metal‐based can be stretched ≈900% strain, its conductivity increases extending 250% retaining initial at 500% strain. Benefitting from these properties, assembled...
The mechanism of near-band-edge (NBE) emission from crystalline ZnO (c-ZnO) nanorods grown on c-Si by a catalyst-assisted vapor-liquid-solid method has been investigated performing temperature-, power-, and time-dependent photoluminescence (PL) measurements at temperature (T) range 143–503K. In contrast to previous reports, we find that the NBE PL is primarily associated with free exciton emission, whereas contribution band-to-band free-to-bound radiative recombinations remains negligible up...
A series of photoluminescence and photoluminescence-excitation spectroscopies have been performed to probe the processes regulating defect-assisted light emission from one-dimensional ZnO nanowire phosphors in a wide temperature range 123–463 K. The observed nonmonotonic change integral defect-photoluminescence intensity as well its peak position with are explained based on interplay competing effects thermal quenching carrier redistribution over radiative channels. temperature-induced...
Single crystalline magnesium oxide (MgO) nanowires exhibiting a square cross section have been grown on (001)-oriented MgO and Si substrates using the vapor-liquid-solid growth mechanism. While grow vertically aligned MgO, they display random orientations silicon substrate. For substrates, selective placement density of can be controlled by electron beam lithography for prepatterning gold catalyst layer. The nanowire samples characterized field-emission scanning microscopy transmission...
Methyl-terminated (110)-oriented silicon surfaces have been prepared from monohydride-terminated, H–Si(110) using a chlorination/alkylation procedure.
We present a facile approach that achieves four-point electrical characterization of silicon microwires fabricated using bottom-up vapour–liquid–solid process.
Abstract High‐T luminescence properties of ZnO nanorods/nanowires grown on c‐Si by a catalyst‐assisted vapor‐liquid‐solid (VLS) method have been studied spectroscopically at the T‐range 123‐573 K. The performed T‐dependent photoluminescence (PL) measurements confirm presence strong ultra‐violet (UV) and visible emission associated with excitonic donor‐acceptor pair recombinations, respectively. A red shift in UV peak position was analyzed within framework three‐parameter model, results...
