BACKGROUND: Modern life prompted man to increasingly generate, transmit and use electricity that leads to exposure to different levels of electromagnetic fields (EMFs). Substantial evidence indicates that exposure to common sources of EMF such as mobile phones, laptops or wireless internet-connected laptops decreases…
Three novel tetrazole-based frustrated magnets, namely, Co3(OH)2(3-ptz)2(SO4)(H2O)4 (1), Co2(OH)(tzba)(H2O)4 (2) and [Co(OH)(tta)] (3) (3-ptz = 5-(3-pyridyl) tetrazole, H2tzba = 4-(1H-tetrazol-5-yl) benzoic acid, Htta = 1H-tetrazole) were hydrothermal synthesized and magnetically characterized. Compound 1 is a 2D (4,4…
The influence of Au nanoparticles (Au NPs) on the aggregation of amyloid-β-(25-35) peptides (Aβ25-35) is investigated by atomic force microscopy and Thioflavin T fluorescence measurements. It is found that, without Au NPs, the Aβ25-35 peptides aggregate gradually from monomers and oligomers to long fibrils with the in…
A novel bipolar host 9-(4-(9H-pyrido[2,3-b]indol-9-yl)phenyl)-9H-3,9'-bicarbazole (pBCb2Cz) was prepared for high efficiency blue phosphorescent organic light-emitting diodes (PhOLEDs), a high triplet energy (ET) material, employing electron-deficient α-carboline. pBCb2Cz (ET = 2.93 eV) was effective as a host materia…
We demonstrate that polyaniline (PANI) behaves as an anode buffer layer, which makes it an excellent hole transport layer. PANI was coated between the photoactive layer and the top anode in transparent flexible organic solar cells (OSCs). The performances of the devices with different PANI thicknesses were investigate…
A key factor in the development of type II diabetes is the loss of insulin-producing beta-cells. Human islet amyloid polypeptide protein (human-IAPP) is believed to play a crucial role in this process by forming small aggregates that exhibit toxicity by disrupting the cell membrane. The actual mechanism of membrane di…
Surfactant-free Co3O4 nanostructures with various particle size ranges were synthesized via the solution combustion method using cobalt nitrate solution as a cobalt precursor and urea as a combustion fuel. Control over average particles size range was achieved by tuning the reaction ignition temperature between 300 °C…
Conventional photosensitizers generally suffer from low efficiency in novel non‐invasive two‐photon photodynamic cancer therapy due to their small two‐photon absorption cross section and they lack an imaging capability for therapy guiding due to their low fluorescence yield. Demonstrated here is the first water‐solubl…
α-Fe(2)O(3) nanofibers are synthesized by a simple and efficient electrospinning method and the selective determination of folic acid (FA) is demonstrated in the presence of an important physiological interferent, ascorbic acid (AA), using the α-Fe(2)O(3) nanofiber modified glassy carbon (GC) electrode at physiologica…
Two heterometallic coordination polymers (CPs) have been prepared using [Ni(II)L]2Co(II) (where H2L = N,N'-bis(salicylidene)-1,3-propanediamine) as nodes and dicyanamido spacers by varying the solvent for synthesis. Structural characterizations revealed that methanol assisted the formation of a two-dimensional (4,4) c…

The development of cell biology, molecular biology, and material science, has been propelling biomimic tissue-engineered skins to become more sophisticated in scientificity and more simplified in practicality. In order to improve the safety, durability, elasticity, biocompatibility, and clinical efficacy of tissue-eng…
Hydroxamic acids and their derivatives have low toxicities and show wide range of biological activities. Copper complexes of phenyl fatty hydroxamic acids (Cu-PFHs) were prepared in a biphasic organic / aqueous medium from phenyl fatty hydroxamic acids (PFHAs) and copper nitrate. The products were separated by decanta…
Anode materials play a key role in the performance, in particular the capacity and lifetime, of lithium ion batteries (LIBs). Silicon has been demonstrated to be a promising anode material due to its high specific capacity, but pulverization during cycling and formation of an unstable solid-electrolyte interphase limi…
Based on an azo-thiol redox reaction, a non-emissive dinuclear iridium(III) complex showed off-on phosphorescent response toward thiols and was developed to image thiol levels in living cells.
We report a nanobelt structured MoO3 intimately wired by carbon nanotube (CNT) networks using a facile hydrothermal synthesis approach. The CNT networks not only serve as a highly conducting and porous scaffold facilitating electron and ion transport but also provided extra space for buffering of strain and stress upo…
In-situ techniques proved to be exceptionally useful tools to understand electrode materials for Li-ion batteries but in-situ neutron diffraction (ND) during battery operation knew a slow development, due to the intrinsic difficulties it held. We have designed a new electrochemical cell, manufactured with a completely…
Nitrogen-doped TiO₂ nanostructures in the form of marigold flowers have been synthesized for the first time using a facile solvothermal method. The structural analysis has shown that such an N-doped TiO₂ system crystallizes in the anatase structure. The optical absorption spectra have clearly shown the shift in the ab…
The aging process causes a number of changes in the skin, including oxidative stress and dyschromia. The kojic acid (KA) is iron chelator employed in treatment of skin aging, and inhibits tyrosinase, promotes depigmentation. Nanotechnology-based drug delivery systems, such as liquid crystalline systems (LCSs), can mod…
