Whether intentionally introduced to exert control over particles and macroscopic objects, such as for trapping or cooling, or whether arising from the quantum and thermal fluctuations of charges in otherwise neutral bodies, leading to unwanted stiction between nearby mechanical parts, electromagnetic interactions play…
This work shows the application of metal ion-implantation to realize an efficient second-generation TiO2 photocatalyst. High fluence Fe+ ions were implanted into thin TiO2 films and subsequently annealed up to 550 °C. The ion-implantation process modified the TiO2 pure film, locally lowering its band-gap energy from 3…
We report that the depolymerization kinetics of cell-penetrating poly(disulfide)s depend exclusively on their length and propose a kinetic uptake model to explain why their intracellular destination changes with the increasing length from the endosomes over the cytosol to the nucleoli.
The construction of a spatially defined assembly of molecular building blocks, especially in the vertical direction, presents a great challenge for surface molecular engineering. Herein, we demonstrate that an electric field applied between an STM tip and a substrate triggered the formation of a bilayer structure at t…
Novel magnetic cellulose–TiO 2 nanocomposite microspheres were prepared successfully by in situ synthesis of TiO 2 nanoparticles in the micro/nanopores of cellulose–Fe 3 O 4 microsphere, which exhibited highly selective enrichment of trace phosphopeptides, as a result of the high-efficiency Lewis acid–base reaction.
The graphene-based transparent and conductive films were demonstrated to be cost-effective electrodes working in organic-inorganic hybrid Schottky solar cells. Large area graphene films were produced by chemical vapor deposition (CVD) on copper foils and transferred onto glass as transparent electrodes. The hybrid sol…
Development of a molecular probe for selective detection of MeHg(+) in the presence of Hg(2+) is a mission impossible to accomplish. Speciation analysis of two substrates with a single kinetic trace exploiting their differential reactivity toward a single probe, i.e., multiplexing in the time domain, is a cost-effecti…
Here we present the development and characterization of a flexible implantable neural probe with glassy carbon electrode arrays. The use of carbon electrodes allows for these devices to be used as chemical sensors, in addition to their typical use as electrical sensors and stimulators. The devices are fabricated out o…
Distributed hydrogen generation from liquid fuels has attracted increasing attention in the past years. Petroleum-derived fuels with already existing infrastructure benefit from high volumetric and gravimetric energy densities, making them an interesting option for cost competitive decentralized hydrogen production. I…
Availability of bio-based chemicals, materials and energy at reasonable cost will be one of the forthcoming issues for the EU economy. In particular, the development of technologies making use of alternative resources to fossil fuels is encouraged by the current European research and innovation strategy to face the so…
This study investigated the effects of higher ethanol blends and an isobutanol blend on the criteria emissions, fuel economy, gaseous toxic pollutants, and particulate emissions from two flexible-fuel vehicles equipped with spark ignition engines, with one wall-guided direct injection and one port fuel injection confi…
A series of porous carbon nanosheet materials with a high nitrogen content have been prepared using melamine and terephthalaldehyde as carbon precursors through the Schiff-base reaction in a molten salt medium.
The search for regenerative agents that promote neuronal differentiation and repair is of great importance. Nerve growth factor (NGF) which is an essential contributor to neuronal differentiation has shown high pharmacological potential for the treatment of central neurodegenerative diseases such as Alzheimer's and Pa…
We study the response of a class of topological systems to electromagnetic and gravitational sources, including torsion and curvature. By using the technology of anomaly polynomials, we derive the parity-odd response of a massive Dirac fermion in $d=2+1$ and $d=4+1$, which provides a simple model for a topological ins…
Abstract Pure biopolymer-based electrospun precursor carbon fibers are fabricated using an abundant and inexpensive biopolymer lignin blended with renewable resource-based cellulose acetate (CA). Iodine treatment on the fabricated green fiber was successfully performed in order to enhance the carbonization process as…
TiO2 photochemistry studies generally address reactions of photogenerated charge-carriers at the oxide surface or the recombination reactions which control the proportion of charge carriers that reach the surface. By contrast, this review focuses on UV absorption, the first photochemical step in semiconductor photocat…
Gelation is enhanced by the addition of sugars and polyols. How, at a microscopic level, do such cosolvents enhance gelation? The following two different hypotheses have been proposed so far to answer this question: (i) enhancement of water structure around the biopolymer induced by cosolvents; (ii) exclusion of cosol…
Weak cell-surface adhesion of cell lines to tissue culture surfaces is a common problem and presents technical limitations to the design of experiments. To overcome this problem, various surface coating protocols have been developed. However, a comparative and precise real-time measurement of their impact on cell beha…
We demonstrate the ultraclean atomic layer deposition (ALD) of Li 2 O and LiOH using lithium tert -butoxide (LiO t Bu) precursor with H 2 O and plasma O 2 as oxidants, along with conversion of Li 2 O and LiOH products to Li 2 CO 3 upon CO 2 dosing. Using LiO t Bu and H 2 O results in LiOH below 240 °C and Li 2 O above…
BACKGROUND: Up-regulation of hsp90 gene expression occurs in numerous cancers such as lung cancer. D,L-lactic-co-glycolic acid-poly ethylene glycol-17-dimethylaminoethylamino-17-demethoxy geldanamycin (PLGA-PEG-17DMAG) complexes and free 17-DMAG may inhibit the expression. The purpose of this study was to examine whet…
