The results of the steady-state and time-resolved fluorescence-spectroscopy measurements and DFT calculations for trans-[4-(4'-dimethylaminostyryl)] pyridine N-oxide (trans-DPO) in various solvents are presented. These results are similar to those reported in the literature for trans-4-(dimethylamino)-4'-cyanostilbene…
Nanoprobe arrays for multiple single cell insertion were developed using heterogeneous nanosphere lithography. Using two heterogeneous nanoparticles as sacrificial and masking particles, high aspect ratio Si nanoprobes were fabricated in an array with spacing between the nanoprobes ranging from a few to tens of microm…
Nanodimensional metallic silver was grown by electrodeposion technique in a semi solid polymer matrix of polyacrylamide. The whole structure looks like dendronic. The average particle diameter of the as grown metallic silver is 13 nm. Nanoindentation study of these nanoparticles shows modulus and hardness value as 103…
We develop a new numerical self-consistent field theory (SCFT) scheme for examining thin film nanostructures of cylinder-forming AB diblock copolymers on a chemically patterned substrate. Using this, we make a systematic analysis to achieve a fundamental understanding of the model system, and the conditions to create…
Novel fluorescent silver nanoclusters prepared by core/shell polymer nanoparticles as templates were applied to detecting copper (Cu2+) ions in aqueous solution based on fluorescence quenching. Changes in fluorescence intensity allow a quick response and sensitive detection of Cu2+ ions at concentrations as low as 20.…
The aim of this study was to develop new dipyridamole (DP) salts with pH-independent solubility for improving oral bioavailability under hypochlorhydria. Salt screening was carried out using nine counterions by the temperature gradient method. Six DP salts were obtained, and there was marked improvement in dissolution…
Nanoparticles of a promising lead‐free solder alloy (Sn3.5Ag (wt.%, SnAg) and Sn3.0Ag0.5Cu (wt.%, SAC)) were synthesized through a chemical reduction method by using anhydrous ethanol and 1,10‐phenanthroline as the solvent and surfactant, respectively. To illustrate the formation process of Sn‐Ag alloy based nanoparti…
The remote welding equipment for nuclear fuel bundle fabrication in a hot-cell was designed and developed. To achieve this, a preliminary investigation of hands-on fuel fabrication outside a hot-cell was conducted with a consideration of the constraints caused by the welding in a hot-cell. Some basic experiments were…
The localization of heat release during deformation of a notched steel plate is studied. It is shown that the source of heat generation in the metal specimen is not the whole region of plastic deformation near the tip of the defect (crack), but only the slip bands occupying the relatively small part of the zone (Chern…
The ability of an object to emit light upon fracture is known as triboluminescence (TL). While no complete theory on TL exists, its applications are limitless. One such use of TL is for detecting damage on aircraft or Lunar habitats. In order to make these sensors more effective, the TL must be bright. Europium dibenz…
Poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles (NPs) were prepared by an O/W emulsion-solvent evaporation method with polyethyleneimine (PEI) in the water phase as a stabiliser. Layer-by-Layer (LbL) assembly was used to engineer the surface of the NPs. Then, the multilayer coated PLGA NPs were further modified vi…
A new method for the development of Electrochromic fabric (ECF) based on polyaniline, instead of traditional Electrochromic device (ECD), is presented in this paper. The transparent conductive layer of ECF is replaced by the conductive fabric; copper coated fabric is used as cathode materials in our experiments. Scann…
To investigate roll bite behaviors in cold foil rolling process, a 2D elasto-plastic finite model is established using FEM software ABAQUS. Contact pressure distribution and roll contour in roll bite are also presented, which demonstrate that foil rolling process is different from conventional strip rolling process. T…
Fluorescently-tagged lipids are a powerful tool for investigating the dynamics of lipids in cell biological studies and in biophysical applications. Herein we report the synthesis and the characterization of a new bola amphiphile, PC12, based on a bisimidic perylene moiety: a central perylene unit is symmetrically lin…
In this paper we have explored how cancer cell line U87MG responds to drug penicillamine (PA) with reciprocal enantiomeric identities (i.e.l, d-forms). As nano-conjugation leads to amplification of chirality, cellular response to respective chiral forms is studied in the presence and absence of nano-conjugation. The l…
Cancer is a major threat to public health and is still one of the leading causes of death worldwide. Cancer biomarkers are extremely important in the process of early detection of cancer, diagnosis, judgment of the curative effect and the prognosis. They also play an important role in mechanistic research into carcino…
The objective of this work was to evaluate the effect of extracts of Ephedra gerardiana loaded onto gelatin particles on human lung epithelial cells. Particles were synthesized using oil‐water emulsification technique and were further stabilized by glutaraldehyde. Particle size was evaluated using SEM and zeta potenti…
By combining elements of hard- and soft-templating, a facile synthesis method for carbon foams with large mesopores has been demonstrated. A commercial Pluronic surfactant was used as the structure-directing agent as well as the carbon precursor. No micelle swelling agent or post treatment is necessary to enlarge meso…
A series of Ti–Mn co-doped Ba2Co2Fe12−2x(Ti–Mn)xO22 (x = 0.2–1.0) Y type hexaferrites has been synthesized by sol–gel method. Single phase hexagonal crystal structure was confirmed by X-ray diffraction analysis and Rietveld refinement with a crystallite size of 30–54 nm of the particles. Ti–Mn doping was uniform in th…
This study presents the investigation of the effects of oxidant type (nitric acid and potassium dichromate), oxidant content (three different levels as 2, 4, and 6 percent) and urea- formaldehyde (UF) resin percentage (two levels as 5 and 7 percent) on mechanical and physical properties of interior grade medium densit…
