A series of conjugated core–shell porous aromatic frameworks are synthesized for selective detection of nitro-explosives. The core–shell PAFs can recognize nitro aromatic explosives in the fluorescent 2D map.
Recently, due to their unique properties, gold nanoparticles (AuNPs) have been used in many biological applications. However, little is known about their toxicity when they come into contact with a biological system. Based on the proposal that AuNPs can have a positive effect on wound healing, the present study invest…
Nanotechnology is making an impact in every field of life. Researchers are expending their interests towards synthesise of gold nanoparticles as they provide superior properties for different types of applications. Conventionally nanoparticles have been synthesised by various physical and chemical methods, having nega…
AIMS: The long-term efficacy of nanoparticles is limited by their rapid metabolism in tissues. In this work, we aim to enhance nanoparticle biostability by preforming a bovine serum albumin (BSA) corona. MATERIALS & METHODS: A BSA corona was formed by incubating poly-3-hydroxybutyrate-co-3-hydroxyhexanoate nanoparticl…
The sensitivities ( S ) of Y 2 O 3 (YAG/LaAlO 3 ):Yb 3+ /Er 3+ phosphors increased with increasing average bond covalency and the calculated values were basically in good agreement with our experimental results.
The early stages of localised corrosion affecting magnesium (Mg) surfaces when immersed in aqueous sodium chloride (NaCl) solutions involves the propagation of dark regions, within which both anodic metal dissolution and cathodic hydrogen evolution occur. For nominally "pure" Mg, these dark areas can either take the f…
Boron nitride nanotubes (BNNTs) have been synthesized by various methods over the last two decades.
Three types of copper sulfides including CuS, Cu7S4 and Cu9S5 were successfully synthesized at different concentrations of ethylenediamine in a liquid phase synthesis process. The whole shape evolution of Cu7S4 microstructures could be manipulated by adjusting the concentration of ethylenediamine. This study indicates…
In the present work, thin ZnO layers were synthesized by the sol-gel method with subsequent spin-coating on Si(100). We show that the detailed analysis of lab-recorded photoemission spectra in combination with Kelvin probe data yielded the work function, ionization energy, and valence band - Fermi level separation - a…
We report the production of an efficient anti-corrosive coating of cold-rolled (CR) steel in a seawater environment (∼3.5 wt% NaCl aqueous solution) using an oil-based graphene oxide ink. The graphene oxide was produced by heating Aeschynomene aspera plant as a carbon source at 1600 °C in an argon atmosphere. The ink…
Anthraquinone (AQ) with electrochemically reversible redox couples is selected to functionalize graphene framework (GF) through non-covalent modification and the composite achieves high specific capacitance, good rate capability and long cycle life.
Carbon in its single layer atomic morphology has exceptional thermal, optical, electronic and mechanical properties, which may form the basis for several functional products and enhanced technologies that go from electricity storage to polymer nanocomposites of so far unsurpassed characteristics. Due to the high cost,…
This article reports the preparation, by means of a masterbatch procedure, of poly (lactic acid) (PLA)/cellulose nanocrystal (CNC) films via premixing 1% wt of CNC into PLA or glycidyl methacrylate (GMA) grafted PLA (g-PLA).
A flexible electroluminescent fiber was developed by incorporating two coaxially wound carbon nanotube sheet electrodes with an active polymer sandwiched between them.
A green method was employed for synthesizing peptide-templated nanoclusters without requiring strong reducing agents. Using synthetic peptide-gold nanoclusters as fluorescence probes, a novel assay for detecting protein kinase is developed based on phosphorylation against carboxypeptidase Y digestion.
First-principle calculations based on DFT were performed to investigate the adsorption properties of amino acids onto graphene surfaces.
MoS 2 QDs with high quantum-yield, variable photoluminescence emission properties and good biocompatibility are studied and applied to the bio-imaging field.
Upon contact with bodily fluids, synthetic materials spontaneously acquire a layer of various species (most notably proteins) on their surface. The concern with respect to biomedical equipment, implants or devices resides in the possibility for biological processes with potentially harmful effects to ensue. In biosens…
Hen Egg White Lysozyme (HEWL) is a widely used exemplar to study protein adsorption on surfaces and interfaces. Here we use fully atomistic Molecular Dynamics (MD) simulations, Multi-Parametric Surface Plasmon Resonance (MP-SPR), contact angle and zeta potential measurements to study HEWL adsorption at a silica surfac…
A BaO infiltrated La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) cathode shows remarkable tolerance and resistance towards chromium via the formation of BaCrO4 instead of SrCrO4 on the electrode surface, preventing the excess Sr deficiency at the A-site of LSCF perovskite and thus mitigating the Cr poisoning effect.
