The ternary solid solution CeO2-ZrO2 is known for its superior performance as an oxygen storage catalyst in exhaust gas catalysis (e.g. TWC), although the defect chemical background of these outstanding properties is not fully understood quantitatively. Here, a comprehensive experimental study is reported regarding de…
Diethylene-glycol/graphene nano-composites were produced by a simple mild solvothermal method, in which diethylene glycol was grafted onto the surfaces of reduced graphene oxides (RGO) as an inter-layer spacer to prevent the aggregation of graphene single sheets, and wet the RGO as well, resulting in good supercapacit…
The objective of this work was to investigate the effect of zein and film formulation on mechanical and structural properties of native (FNS), and oxidized with 2.5% (FOSA) and 3.5% (FOSB) banana starch. The oxidized starch showed differences from native starch due to the oxidation process, showing a decrease in lipid…
Poly(3-hydroxybutyrate) [P(3HB)] and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) [P(3HB-co-3HV)] are produced by various microorganisms as an intracellular carbon and energy reserve from agricultural feedstocks such as sugars and plant oils under unbalanced growth conditions. P(3HB) and P(3HB-co-3HV) have attracted t…
Over the last years, a number of therapeutic strategies have emerged to promote axonal regeneration. An attractive strategy is the implantation of biodegradable and nonimmunogenic artificial scaffolds into injured peripheral nerves. In previous studies, transplantation of decellularized veins filled with spider silk f…
We prepared the bioactive liquid crystal (LC) droplets by decorating an oligopeptide at the LC/aqueous interface to stabilize the LC droplets. These LC droplets can be used to detect proteases through the specific cleavage of protease on an oligopeptide leading to a bipolar-to-radial transition of LC configuration ins…
Self-doped Cu2-xS nanocrystals (NCs) were converted into monodisperse Cu2-xS-Au2S NCs of tunable composition, including pure Au2S, by cation exchange. The near-infrared (NIR) localized surface plasmon resonance (LSPR) was dampened and red-shifted with increasing Au content. Cation exchange was accompanied by eliminati…
We report a one-step method of assembling supramolecular colloidosomes at the interface of microfluidic droplets. The self-assembly process utilises a versatile CB[8] host-guest system to reversibly crosslink polystyrene nanoparticles via a polyacrylamide linker. These micrometre-sized hollow structures can be loaded…
Ultrasmall copper nanoparticles (1.6 nm) on silica catalysts were successfully prepared via an in situ self-assembled core–shell precursor route. XRD, SEM-EDS and chemisorption results showed that only fatty acids with carbon chain length > 2 carbon atoms could effectively promote the dispersion of copper on silica. X…
microcarriers. Since this inorganic material exhibits high solubility in acids, the release of protein from the carriers can be controlled via the pH of the environment. The process results in the successful generation of bulk amounts of monodisperse and colloidally stable microspheres with diameters as small as 300 n…
The increase in oxygen functionalities on GO with increasing use of oxidizing agent results in (i) amplification of redox pseudocapacitive current and (ii) improves metal ion adsorption.
A synthetic strategy has been developed for the preparation of anionic carbosilane dendrimers bearing sulfonate or carboxylate groups at their periphery by means of thiol-ene chemistry. It offers significant advantages, such as milder reaction conditions, shorter reaction times and more facile purification methods, wh…
There exists a knowledge gap in understanding potential toxicity of mesoporous silica nanoparticles. A critical step in assessing toxicity of these particles is to have a wide size range with different chemistries and physicochemical properties. There are several challenges when synthesizing mesoporous silica nanopart…
Graphene is the strongest material but its performance is significantly weakened by vacancy defects. We use molecular dynamics simulations to investigate the tensile behavior of a graphene which contains a single vacancy defect. Our results suggest that because of the single vacancy, the fracture strength of graphene…
The reaction process of UA on the surface of Fc@β-CD/CND/GCE.
This work presents a systematic approach to evaluate the physio-mechanical properties of bean pod ash particles (BPAp) reinforced recycled polyethylene (RLDPE) polymer based composites. The bean pod ash particles of 75 μm with a weight percentage of 0, 5, 10, 15, 20, 25, 30 (wt%) and recycled polyethylene (RLDPE) were…
We report the atomic-scale structure of a Zn₁₅₂Al-borate layered double hydroxide (LDH) nanosheet, as determined by reverse Monte Carlo (RMC) modelling of X-ray total scattering data. This study involves the extension of the RMC method to enable structural refinement of two-dimensional nanomaterials. The refined LDH m…
Design of optical molecular probes for selective detection of aromatic thiols has attracted much attention. Although several types of probes have been proposed, all of them exhibit colorimetric or fluorometric response via irreversible reaction with aromatic thiols and cannot be reused. Here we report that a spiropyra…
Bulk proton mobility and catalytic activity to surface oxygen reduction are the two factors for determining the effectiveness of cathode materials for protonic-solid oxide fuel cells (p-SOFCs).
Elastico-mechanoluminescence (EML) of diphase (Ba,Ca)TiO <sub>3</sub> :Pr <sup>3+</sup> ,RE (RE includes all rare-earth-ions except Sc and Pm) is systematically investigated.
