A single-layer nanogrid of thiol graphene/Prussian blue (tG/PB) composite film was constructed to realize the high electrocatalytic biosensing of various physiological substances under the low potential. In order to achieve this architecture, a single layer of deformed polystyrene (PS) beads was first prepared as the template for the PB deposition. The structure of PB film can be well controlle...
Nanogenerators with capacitor structures based on piezoelectricity, pyroelectricity, triboelectricity and electrostatic induction have been extensively investigated. Although the electron flow on electrodes is well understood, the maximum efficiency-dependent structure design is not clearly known. In this paper, a clear understanding of triboelectric generators with capacitor structures is pres...
Carbon dots of small carbon nanoparticles surface-functionalized with 2,2'-(ethylenedioxy)bis(ethylamine) (EDA) were synthesized, and the as-synthesized sample was separated on an aqueous gel column to obtain fractions of the EDA-carbon dots with different fluorescence quantum yields. As already discussed in the literature, the variations in fluorescence performance among the fractions were att...
A new graphene-based composite structure, monolayer-ordered macroporous film composed of a layer of orderly arranged macropores, was reported. As an example, SnO2-reduced graphite oxide monolayer-ordered macroporous film was fabricated on a ceramic tube substrate under the irradiation of ultra-violet light (UV), by taking the latex microsphere two-dimensional colloid crystal as a template. Grap...
A study was conducted to develop banana flour based edible film using Response Surface Methodology. A Central Composite Design was adopted in the optimization of banana flour and sodium alginate level for the development of edible film with 13 different runs and 5 trials of two similar centre points. Effects of banana flour (2-4% w/v) and sodium alginate (0.5-1.0% w/v) level on the thickness, m...
Lysozyme–chitosan composite films were developed for enhancing the antimicrobial properties of chitosan films. A 10% lysozyme solution was incorporated into 2% chitosan film-forming solution (FFS) at a ratio of 0%, 20%, 60%, and 100% (w lysozyme/w chitosan). Films were prepared by solvent evaporation. Lysozyme release from the film matrix, the antimicrobial activity of films against Escherichia...
This research work presents an understanding of structure-property relationship in uniaxially oriented multilayer polypropylene (PP) film/foams. Multilayer PP film/foams having 16 layers have been produced by using a unique coextrusion and multiplication technique. A post-uniaxial drawing process at a certain temperature has been carried out to orient the multilayer film/foams in extrusion dire...
Whilst polystyrene microgels belong to the oldest family of microgel particles, their behaviours when deposited onto substrates or prepared as composites have received little attention. Because polystyrene microgels are solvent-swellable, and inherently colloidally stable, they are well suited to form composites with conjugated polymers. Here, we investigate the morphology and light absorption ...
The lubrication performance of journal bearings with different sorts of uniformly distributed micro-spherical textures are studied in this paper. Geometries and dynamic models of journal bearings with pure concave/convex textures are developed. The validity of the proposed models is verified against the oil film pressure distribution from the literature. The effects of geometry parameters (the ...
Electrochemical impedance and self-discharge studies were carried out to investigate lithium intercalation into bare and Ni-coated KS10 graphite. Values of the charge-transfer resistances, exchange current densities, surface film resistances, and lithium-ion diffusion coefficients as functions of the state of charge (SOC) all favored the 10 wt % Ni composite KS10 graphite over bare KS10 graphit...
