Conjugation of the (64)Cu PET radioisotope (t(1/2) = 12.7 hours) to long circulating liposomes enables long term liposome tracking. To evaluate the potential clinical utility of this radiotracer in diagnosis and therapeutic guidance, we compare image contrast, tumor volume, and biodistribution of (64)Cu-liposomes to m…
Thienyl-substituted tetrathiafulvalene (DTh-TTF, 1a) and a t-butyl derivative (1b) are prepared, and the remarkable photoresponse and memory effect in the transistors are investigated. Upon irradiation of light with a wavelength shorter than the absorption edge (535 nm), the threshold voltage of 1b shifts by as large…
Nanotechnology As A Food Perspective Nanotechnology is a field of science and technology which is generally interested in particles that are smaller than 1-100 nm (billionth of a meter) and it is grown rapidly in recent years. It deals with molecules, atoms and these kind of structures which has nano-scale dimensions.…
Poly(sodium methacrylic acid) brushes are perpendicularly grafted onto graphene oxide and reduced graphene oxide, and used as templates for loading MnO2 nano-particles. The modified graphene oxide has a high loading amount against modified reduced graphene oxide for the more effective three dimensional polymer structu…
La0.8Sr0.2MnO3-δ (LSM) perovskite was synthesized using different methods, such as solid state reaction, soft-chemical and sol-gel methods for solid oxide fuel cells (SOFCs) for use as a cathode material. The pristine material was characterized by X-ray diffraction, thermogravimetric analysis (TGA), differential scann…
Wet-chemically synthesized colloidal semiconductor nanocrystals are unique chromophores which possess properties such as size-dependent absorption and emission, large action cross-sections and flexible surface chemistry. This Perspective summarizes efforts in the field to incorporate these nanocrystals into sol-gel de…
Silica hollow microspheres (SHMs) with size-tunable penetrating macropores from 250 nm to 560 nm are prepared by a water/oil/water ternary phase emulsion system. Furthermore, the thus-obtained SHMs can serve as a superior support to fabricate supported palladium catalysts for the hydrogenation of bulky polystyrene mol…
It is shown that the absorption properties in the visible region of polymer films based on mixtures of terthiophene and bithiophene may be tailored to suit the needs of optical devices such as solar cells, sensors and organic light emitting diodes. Using vapor phase polymerization (VPP) with iron(III) p-toluenesulfona…
It has previously been demonstrated that phenanthroline-based ligands used to make gold metallotherapuetics have the ability to exhibit cytotoxicity when not coordinated to the metal center. In an effort to help assess the mechanism by which these ligands may cause tumor cell death, iron binding and removal experiment…
In this paper, we investigate the effect of electrical pulse bias on DNA hybridization events in a biosensor platform, using a Carbon Nanotube Network (CNN) and Gold Nano Particles (GNP) as an electrical channel. The scheme provides both hybridization rate enhancement of bio molecules, and electrical measurement in a…
An efficient method has been developed to synthesize well-aligned multi-walled carbon nanotubes (MWCNTs) on a conductive Ta substrate by chemical vapour deposition (CVD). Free-standing MWCNTs arrays were functionalized through electrochemical oxidation with the formation of hydroxyl and carboxyl functional groups. Usi…
Hydrocode simulations are carried out using Ansys Autodyn (version 11.0) to study the effects of the liner material (mild steel, copper, armco iron, tantalum, and aluminum) on the shape, velocity, traveled distance, pressure, internal energy, temperature, divergence or stability, density, compression, and length-to-di…
A class of new compounds consisting of a tetraphenylethene (TPE) core and hydrophilic peripheral oligo(ethylene glycol) chains was synthesized. These newly synthesized compounds showed aggregation-induced emission (AIE) nature which originated from the TPE core, and their peripheral oligo(ethylene glycol) chains impar…
This study presents an effective approach to significantly reduce the electrical resistivity of thermally responsive shape memory polymer (SMP) nanocomposites that show Joule heating triggered shape recovery. Carboxylic acid-functionalized carbon nanotubes (CNTs) self-assembled and grafted onto the carbon fibers, were…
The geometrical and spectral properties of the hydrogen-bonded clusters formed by 6-aminocoumarin (6AC) with solvents of different hydrogen-bonding abilities have been investigated at the CPCM-PBE0/6-311??G(d, p) level of theory. Upon photoexcitation, A type hydrogen bonds will be weakened whereas hydrogen bonds of B…
The discovery of some Aurivillius materials with high Curie temperature or fatigue-free character suggests possible applications in high temperature piezoelectric devices or non-volatile ferroelectric random access memories. Furthermore, increasing concerns for environmental issues have promoted the study of new leadf…
A simple method has been developed for the isolation of Acid Soluble Collagen (ASC) and Pepsin Digestible Collagen (PDC) from the skin of Albacore tuna (Thunnus alalunga), Dog shark (Scoliodon sorrakowah), and one among Indian Major Carps ie, Rohu (Labeo rohita). Biochemical characterization of the collagen extracted…
Composites are emerging as realistic alternatives to the metal alloys in many applications like automobiles, marine, aerospace applications, sports goods, etc. Fiber composites offer many advantages such as low specific gravity, tensile strength and modulus, compressive strength and modulus, better fatigue strength, e…
In this research we calculate the band gap of ZnS nano particle and show that it increases with decreasing its size. The simplest way for discussing this phenomenon and finding the band gap for different sizes is effective mass approximation. We show, this method isn't accurate for particles smaller than 2.5 nm. This…
Nanoparticles can occur naturally or be intentionally engineered. The field of nanotechnology has varied influence on industry and segments of our daily life. The health effects associated with human exposure to nanoparticles remains elusive and very little has been done with respect to investigate the genetic and epi…
