Carbon nanocoils (CNCs) are employed to fabricate fast, high-resolution, and reversible humidity sensor based on a flexible liquid crystal polymer (LCP) substrate. The displays fast-response (1.9 s) recovery time (1.5 s), broad relative (RH) detection range (4–95%), linearity, repeatability, stability. rapid response considered benefit from the hydrophobic effect of LCP substrate high purity CNCs, which give rise weak physical adsorption. Meanwhile, sensitivity results both unique helical...
Abstract Pseudo-topotactic conversion of carbon nanotubes into one-dimensional nanowires is a challenging but feasible path to obtain desired diameters and morphologies. Here, previously predicted experimentally unobserved allotrope, T-carbon, has been produced from pseudo-topotactic multi-walled nanotube suspension in methanol by picosecond pulsed-laser irradiation. The as-grown T-carbon have the same diameter distribution as pristine nanotubes, characterized high-resolution transmission...
Abstract Chronic kidney disease (CKD) is one of the most serious non‐communicable diseases affecting population. In early‐stages patients have no obvious symptoms, until it becomes life‐threatening leading end‐stage failure. Therefore, important to early diagnose CKD allow therapeutic interventions and progression monitoring. Here, a point‐of‐care (POC) sensing platform reported for simultaneous detection three biomarkers, namely creatinine, urea, human serum albumin (HSA), using reduced...
Metal organic frameworks (MOFs) with two dimensional (2D) nanosheets have attracted special attention for supercapacitor application due to their exceptional large surface area and high surface-to-volume atom ratios. However, electrochemical performance is greatly hindered by poor electrical conductivity. Herein, we report a 2D nanosheet nickel cobalt based MOF (NiCo-MOF)/reduced graphene oxide heterostructure as an electrode material supercapacitors. The NiCo-MOF are in situ grown on rGO...
Gold nanorods (GNRs) with different localized surface plasmon resonance (LSPR) peaks and thicknesses of polymer-coating were synthesized to validate that the distinct GNR-based quenching process quantum dot (QD) emission follows metal energy transfer theory. The efficiency is directly related spectral overlap GNR-LSPR absorption QD-emission, as well separation distance between two nanoparticles. GNRs are advantageous for DNA conjugation, high GNR-QD system was utilized sensitive detection.
Mesoporous encapsulation of gold nanorods (GNRs) in a silica shell controllable thickness (4.5-25.5 nm) was realized through single-step coating method without any intermediary coating. The dependence localized surface plasmon resonance (LSPR) extinction spectra the coated GNRs on investigated with both simulation and experiments, which agreed well each other. It found that cetyltrimethyl ammonium bromide (CTAB) molecules, act as surfactants for dissociate solution, greatly affect...
