Cooperative self-assembly (co-assembly) of diblock copolymers (DBCs) and inorganic precursors that takes inspiration from the rich phase separation behavior DBCs can enable realization a broad spectrum functional nanostructures with desired sizes. In DBC assisted sol–gel chemistry approach polystyrene-block-poly(ethylene oxide) ZnO, hybrid films are formed slot-die coating. Pure printed as cont...

• Spherical carbon product self-generated from hydrothermal supernatant. Self-generated lower in inorganic content than carbon. Different 13 C NMR spectra to precursor indicating new formation. Activated stable under electrochemical cycling (>20000 cycles). Retention of high levels nitrogen (>6 at%). This work provides the first observations and insights into self-generation microspheres supern...

Gunshot residue (GSR) is an important type of forensic trace evidence produced when a firearm discharged. Currently, inorganic GSR particles are used for establishing the fact shooting. The organic gunshot (OGSR) has been recently shown to have great potential providing additional information vital crime scene investigation. Smokeless powder precursor OGSR and one its chemical components. In th...

Fundamental reaction processes between vapor-phase chemical precursors and high molecular weight polymers are important for polymer coating, encapsulation and surface modification. Using trimethylaluminium and water in an atomic layer deposition (ALD) exposure sequence, reactions between vapor-phase trimethylaluminium and common polymers with different substituents are quantified using in situ ...

Zirconium oxide (ZrO2) has generated wide interest because of its potential in applications such as solid oxide fuel cells, catalysts and optical devices. In these applications, it is important to control the grain size of the material and increase the surface area by introducing porosity with tailored pore size. This paper presents a synthesis route for the preparation of mesoporous zirconia u...

In the solution processing of oxide electronics, the structure of metal-organic precursors in solution and their effect on processability and on the final structure and properties of the oxide have rarely been studied. We have observed that hybrid clusters, having inorganic cores coordinated by organic ligands, are the typical form of metal-organic precursor structures. For insulating ternary L...

The effect of heterogeneous aqueous reactions on the secondary formation of inorganic aerosols during haze events was investigated by analysis of comprehensive measurements of aerosol composition and concentrations [e.g., particular matters (PM2.5), nitrate (NO3), sulfate (SO4), ammonium (NH4)], gas-phase precursors [e.g., nitrogen oxides (NOx), sulfur dioxide (SO2), and ozone (O3)], and releva...

The colloidal nature of perovskite precursor solution highly determines the quality film and photovoltaic performance a solar cell (PSC). Herein, we demonstrate facile method to fabricate high-quality all-inorganic CsPbIBr2 by regulating temperature solution. After characterization, stable microcrystals with size up 1 have been formed under high temperatures, more suitable for preferable crysta...

In this project, we study SiC nanoporous membranes, which exhibit the potential to overcome many of the difficulties other inorganic membranes face, particularly under conditions typically encountered in reactive separations for H2 production, and in fuel-cell applications. In particular, we systematically investigate and further develop the technique of pre-ceramic polymer pyrolysis to produce...

The aims of this study was to determine the effect of organic and inorganic Zn and Cu supplements on performance, footpad dermatitis (FPD), carcass characteristics and blood profile in broiler chickens. A total of 336 one-day-old Ross 308 broiler chicks were distributed into 24 floor pen and reared for 42 days. A basal mineral premix (without Zn and Cu) was supplemented with organic or inorgani...
