We report the improvement of a CdSe quantum-dot-sensitized solar cell (QDSSCs) based on surface modification of Cu 2 S nanoparticle counter-electrodes (CEs).
The short-range interaction between Cr atoms was directly examined by scanning tunneling microscopy measurements on a Zn(0.95)Cr(0.05)Te film. Our measurements revealed that a Cr atom formed a localized state within the bandgap of ZnTe and this state was broadened for a pair of Cr atoms within a distance of ∼ 1 nm.
Variation in composition provides an additional degree of freedom in nanocrystals design.
A novel inorganic–organic core–shell nanocomposite, poly(N-isopropyl acrylamide) coated silica nanoparticles (PNIPA-g-FSNP), has been synthesized sonochemically for the first time following the principles of green methods. The sonochemical method eliminates the requirement for organic solvents, cross-linkers and hydro…
We study the sedimentation process of a binary colloidal soft sphere system where significant overlaps of the particles are possible. We employ estimates of the equation of states in the small and large pressure limit in order to predict the final states of the sedimentation process. Furthermore, Brownian dynamics sim…
The reaction of NdCl3 with 1,3-bis(1,3-dimethyl-1H-pyrazol-4-yl)propane-1,3-dione (HL) and 1,10-phenanthroline (Phen) in the presence of a base afforded complex [Nd(L)3Phen] (I). Unstable solvate I · 2CH2Cl2 was obtained from a solution of the complex in dichloromethane, and its structure was determined by X-ray diffr…
An improved mathematical model describing acoustic emission (AE) signals generated by different types of partial discharges (PD) that occur in electric power transformer insulation system is presented in the paper. AE signals are analyzed within the AE method as applied for power transformer failure detection due to o…
We report the lithography-assisted alignment control of one-dimensional (1D) mesochannels. The effectiveness on both nonionic and cationic surfactants is discussed, and a continuous film with fully uniaxially oriented mesochannels is also successfully prepared.
The excellent performance, recently reported in the literature, of a solid-state oxygen concentration cell equipped with an alkali carbonate-based electrode has been interpreted in accordance with the proposition that the carbonate is an alkali-ion conductor. This interpretation is the consequence of all facts known a…
Two bolaamphiphilic compounds with identical acetylcholine (ACh) head groups, but with different lengths of an alkyl chain pendant adjacent to the head group, as well as differences between their hydrophobic skeleton, were investigated for their ability to self-assemble into vesicles that release their encapsulated co…
The size or alkyl chain length of cationic surfactants can be used to tailor both the pore morphology and the functionality or oxidation state of cobalt in silica materials.
The novel negative-type photosensitive polyimide precursor to protect ELK for Flip-chip package was developed. High modulus was achieved by the rigid structure of main polymer, and film transparency was achieved to modify the side chain unit by tuning the ratio of particular non-acryloyl groups and acryloyl groups. Th…
This study was conducted to see the effect of a mixture of ZnS nanoparticles and PVA on the properties of nanocomposite PV / ZnS. Mixing is done with the sol-gel method, which dissolve ZnS nanoparticles and PVA with distilled water. Stirring is done through the magnet, with the angular velocity of 500 rpm, and heated…
This paper concerns the ITER project demands to provide the machine reliability and the human safety along and after the ITER operation for making the personnel access inside the ITER bioshield possible. New results are presented for radiation streaming inside the gaps of Diagnostic Equatorial Port Plug (EPP) of ITER…
Formation of a five-membered strong triazole ring to facilitate the highly stable anchoring of LC droplet encapsulated polymer capsules over a patterned substrate.
The first tetratopic pyrimidine-hydrazone (pym-hyz) molecular strands containing terminal hydroxymethyl (L1) and acryloyl (L2) functional groups have been synthesised. L1 was produced by step-wise imine condensation reactions, starting with 6-hydroxymethyl-2-pyridinecarboxaldehyde. L2 was then synthesised through the…
The strength of coke largely depends on the thermoplastic and dilatation behavior of its coal constituents. Therefore, understanding the behaviors that ensure high-strength coke is important. In this study, the combination of blended coal was varied and (in a separate experiment) asphalt pitch (ASP) was added to the b…
In recent years, significant developments have been achieved in the field of tissue engineering. Biopolymers and bioceramics are known to play major role in the construction of artificial organs. Chitosan is one of the biopolymers extensively studied for tissue engineering, drug delivery, and wound healing application…
Polyphosphazene/SiO 2 composite membranes and porous polyphosphazene membranes were prepared and their properties were studied in detail.
This study provides a one-step strategy for preparing DNA–Au hybrids as SERS-active substrates by the simple mixing of DNA and Au colloids.
