Abstract Recent achievements in amorphous/crystalline silicon heterojunction (SHJ) solar cells and perovskite/SHJ tandem place hydrogenated amorphous (a-Si:H) at the forefront of photovoltaics. Due to extremely low effective doping efficiency trivalent boron tetravalent silicon, light harvesting aforementioned devices is limited by their fill factors (FFs), a direct metric charge carrier transport. It challenging but crucial develop highly conductive doped a-Si:H with minimal FF losses. Here...
A novel composite of vinyl group functionalized multiwalled carbon nanotubes (MWCNTs) molecularly imprinted polymer (MIP) was synthesized and applied as a molecular recognition element to construct an electrochemical sensor for parathion-methyl in this paper. The special properties mainly dominated by π–π, p–π interaction hydrogen bonding formed among functional monomer, template matrix. series experiment results proved that the prepared material had good adsorption capacity fast mass...
Fluoride ion (F–), the smallest anion, exhibits considerable significance in a wide range of environmental and biochemical processes. To address two fundamental unsolved issues current F– sensors based on specific chemical reaction (i.e., long response time low sensitivity) as part our ongoing interest spiropyran sensor design, we reported here new sensing approach that, via assembly F–-specific silyl-appended dye with graphene oxide (GO), allows rapid sensitive detection aqueous solution....
To satisfy the requirement of simultaneous extraction and characterization diverse kinds multitarget analytes, preparation, characterization, application a novel tetraazacalix[2]arene[2]triazine (TCT) coated magnetic nanoparticle (TCT MNP) adsorbent are presented in this paper. TCT assembles two benzene rings triazines with nitrogen cross-bridging links, which exhibits unique structural framework versatile recognition features based on multiple sites. These include π electron stacking,...
The unique properties of covalent triazine-based organic framework/polymers, including large surface area, hydrophilic–lipophilic-balanced adsorption, and economical preparation, make it a promising candidate as stationary phase for high-performance liquid chromatography. However, irregular shapes wide size distributions such particles hinder column packing, resulting in low efficiency or high back pressure. Herein, we describe the fabrication SiO2@ polymer (CTP) core–shell microspheres with...
Locust powder was converted into water-soluble fluorescent nitrogen-doped carbon dots (N-CDs) with gram-scale yield through a self-exothermic reaction between nitric acid and diethylenetriamine (DETA) within 10 min. The morphology, elemental information, optical properties of the N-CDs were characterized using high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, Fourier-transform infrared, ultraviolet-visible fluorescence spectroscopy. Spectroscopic...
Abstract Silicon‐based photovoltaic (PV) modules suffer from potential‐induced degradation (PID) caused by sodium (Na) permeation, which is present in large quantities soda‐lime glass. Here, we report that Na atoms can decrease the performance of amorphous/crystalline silicon heterojunction (SHJ) solar cells without help a voltage bias. The three stages are investigated this work. First, H 2 O molecules open channels for transport transparent conductive oxide (TCO), while device remains...
In this study, nitrogen-doped carbon dots (N-CDs) with excellent peroxidase-like activity were prepared using locust powder as the source by a self-exothermic reaction. The obtained N-CDs could catalyze oxidation of chromogenic substrate 3,3′,5,5′-tetramethylbenzidine (TMB) in presence H2O2 to generate blue oxidized product (TMBox) maximum absorption peak at 654 nm. catalytic reaction conditions optimized; furthermore, steady-state kinetic analysis indicated that exhibited high affinity...
A "dual-purpose reagent" strategy was developed for the facile synthesis of magnetic Fe3O4 nanoparticle/hyper-cross-linked polymers (MHCPs). Ferric chloride serves both as a catalyst Friedel–Crafts reaction and an iron source preparation nanoparticles. This method is advantageous in terms simplicity, eco-friendliness, cost-effectiveness. variety analytical techniques such scanning electron microscopy, transmission Fourier transformed infrared spectra were employed to characterize composites....
Two-photon excitation (TPE) with near-infrared (NIR) photons as the source has important advantages over conventional one-photon (OPE) in field of biomedical imaging. β-cyclodextrin polymer (βCDP)-based two-photon absorption (TPA) fluorescent nanomicelle exhibits desirable two-photon-sensitized fluorescence properties, high photostability, cell-permeability and excellent biocompatibility. By combination nanostructured dye (TPdye)/βCDP TPE technique, herein we have designed a TPdye/βCDP...
