We developed a simple high-throughput colorimetric assay to detect glucose based on the glucose oxidase (GOx)-catalysed enlargement of gold nanoparticles (AuNPs). Compared with the currently available glucose kit method, the AuNP-based assay provides higher clinical sensitivity at lower cost, indicating its great pote…
We report the synthesis of tuneable ultra high specific surface area Aqueous Miscible Organic solvent-Layered Double Hydroxides (AMO-LDHs). We have investigated the effects of different solvent dispersion volumes, dispersion times and the number of re-dispersion cycles specific surface area of AMO-LDHs. In particular,…
In situ reduction of aqueous graphene oxide is undertaken to challenge the prevailing assignation of molecular transitions in photoluminescence spectra.
Halloysite nanotubes (HNTs), due to their unique structures and properties, may play an important role in biomedical applications. In vitro test is usually conducted as a preliminary screening evaluation of the hemocompatibility and cytotoxicity of HNTs for its short term consuming, convenience, and less expense. In t…
Carbon nanomaterials have a great potential in environmental studies; they are considered as superior adsorbents of pollutants due to their physical and chemical properties. Functionalization and dimension play an important role in many functions of these nanomaterials including adsorption. In this research, adsorptio…
The isomerization of spiropyrans in crystals was realized under high pressure, and the corresponding mechanochromic response could be observed by the naked eye. In situ UV-Vis spectroscopy study demonstrated that the equilibrium constant increases with the increasing pressure, from which we proposed that the negative…
Recent research has indicated that polydopamine and synthetic eumelanins are optoelectronic biomaterials in which one-dimensional aggregates composed of ordered-stacking oligomers have been proposed as unique organic semiconductors. However, improving the ordered-stacking of oligomers in polydopamine nanostructures is…
Direct production of BuOH from EtOH is compared over four Cu catalysts, supported on different solid acids. The activity of these catalysts to perform the Guerbet reaction was assessed using a continuous flow reactor and the effect of using scCO 2 was also monitored. Cu on high surface area CeO 2 showed the best activ…
Ag–ZnO heterostructured nanoparticles by a one-step solvothermal route exhibit outstanding photocatalytic efficiency for Congo red in aqueous solution under visible light irradiation.
Ni 3 (PO 4 ) 2 @GO and Fe 2 O 3 @GO have been successfully synthesized as electrode materials, and they have been used to assemble an asymmetric supercapacitor (Fe 2 O 3 @GO//Ni 3 (PO 4 ) 2 @GO), which exhibited a high energy density.
Thermal coupling between citric acid and Na-salt of glycine, l -valine and l -isolucine produced blue emitting carbon dots (CDs) and in presence of NaH 2 PO 4 , produced green emitting phosphorous doped CDs (PCDs), which were utilized for cell imaging.
A scalable industrial method for graphene and Few-Layer-Graphene (FLG) production by graphite delamination in N -methylpyrrolidone and water–surfactant mixtures using a high pressure homogenizer is presented.
A double hydrolysis reaction provides a simple strategy to construct layered single hydroxides with superstructures for electrochemical energy storage.
A 3d hierarchical porous carbon fiber was fabricated by phase-separable wet-spinning and the subsequent activation for high-performance supercapacitors.
Herein, papain-functionalized Cu nanoclusters (CuNCs@Papain) were originally synthesized in aqueous solution together with a quantum yield of 14.3%, and showed obviously red fluorescence at 620 nm. Meanwhile, their corresponding fluorescence mechanism was fully elucidated by fluorescence spectroscopy, HR-TEM, FTIR spe…
Manipulation of upconversion (UC) emission is of particular importance for multiplexed bioimaging. Here, we precisely manipulate the UC color output by utilizing the phonon-assisted energy back transfer (EBT) process in ultra-small (sub-10 nm) Gd2O3:Yb(3+)/Er(3+) UC nanoparticles (UCNPs). We synthesized the Gd2O3:Yb(3…
The anticorrosion and tribocorrosion properties of a multilayer diamond-like carbon (DLC) film were systematically investigated in NaCl solution.
A pair of hetero-bimetallic lanthanide complexes containing terbium and europium ions have been prepared by coupling kinetically stable complexes together using an Ugi methodology to incorporate a naphthyl chromophore. Both complexes exhibit emission from terbium and europium in solution. The terbium centred emission…
Three new chalcone derivatives were synthesized, characterized, investigated for photo-cross-linking characteristics, and used as corrosion inhibitors for mild steel in 1 M HCl using electrochemical, spectroscopic and theoretical methods.
We discuss fabrication techniques for porous metals with the focus on how to control the architecture over several length scales.
