The effect of external electric field on electron-hole (eh) correlation in gallium arsenide quantum dots is investigated. The electron-hole Schrodinger equation in the presence of an external electric field is solved using explicitly correlated full configuration interaction method and accurate exciton binding energy…
The analysis of nanomaterials in pharmaceutical or cosmetic preparations is an important aspect both in formulation development and quality control of marketed products. Despite the increased popularity of nanoparticulate compounds especially in dermal preparations such as emulsions, methods and protocols of analysis…
In this work, we have considered and compared two molecular dynamics schemes widely used when studying a thin fluid film confined between solid surfaces and undergoing boundary shear. In the first approach, the non-equilibrium simulations are performed on a confined fluid explicitly connected to bulk reservoirs. In th…
Protein-protein interactions are the basis of many biological processes and are governed by focused regions with high binding affinities, the warm- and hot-spots. It was proposed that these regions are surrounded by areas with higher packing density leading to solvent exclusion around them - "the O-ring theory." This…
To address the issue of the pseudogap in the superconducting state of the high temperature superconducting cuprates, we studied the temperature dependent redistribution of the spectral weight in the \textit{c}-axis polarized optical spectra for underdoped YBa$_{2}$(Cu$_{1-x}$Zn$_{x}$)$_{3}$O$_{7-\delta}$ single crysta…
The development of clinically relevant preclinical models that mimic the hallmarks of neurodegenerative disease is an ongoing pursuit in early drug development. In particular, robust physiological characterization of central nervous system (CNS) disease models is necessary to predict drug delivery to target tissues an…
We are motivated to compute delicate chemical vapor deposition (CVD) processes. Such processes are used to deposit thin films of metallic or ceramic materials, such as SiC or a mixture of SiC and TiC. For practical simulations and for studying the characteristics in the deposition area, we have to deal with delicate m…
In this study, porous titanium was treated by a hydrogen peroxide solution with (HT) or without (HO) tantalum chloride at a low temperature to endow its bioactivity. The microstructure, film stability and in vitro and in vivo bioactivity of HT-treated and HO-treated porous titanium were investigated, and the non-treat…
Abstract We present results of development of CdZnTe semi‐insulating crystals prepared by Vertical Gradient Freeze method in a 4‐zone furnace. We applied the way of growth of the crystal from the top when the first crystallization seed is created on the surface of the melt. The typical height of the crystals is 5 cm.…
Selective dehydrogenation of the biomass-derived lignan hydroxymatairesinol (HMR) to oxomatairesinol (oxoMAT) was studied over an Au/Al(2)O(3) catalyst. The reaction was carried out in a semi-batch glass reactor at 343 K under two different gas atmospheres, namely produced through synthetic air or nitrogen. The studie…
Guided-mode resonances have been exploited to filter the normal-incidence transmission of mid-infrared wavelengths through a photonic crystal slab. A two-dimensionally periodic structure has been integrated with a quantum dot infrared photodetector to narrow its mid-wavelength infrared photoresponse spectrum. Finite-d…
In recent years, the development of nanotechnology opens up new prospects for biomedical applications of unmodified and chemically modified diamond nanoparticles (DNPs). The problem of biocompatibility of DNPs is thus of primary importance. The first step in the modification of DNPs is usually the introduction of -OH…
levels. The effects of pH on gold loading, particle size and particle size distribution are studied, both below and above the isoelectric point of TiO2. The effects of adjusting the pH before and after the addition of the support to gold chloride solution are also investigated. Gold particles with diameters of less th…
We report a novel fabrication method for ordered arrays of metal nanoparticles that exploits the uniform arrangement of polymer beads deposited as close-packed monolayers. In contrast to colloidal lithography that applies particles as masks, we used thermal decomposition of the metal-covered particles to precisely def…

Shallow lakes from the Pampa plain (Argentina) are subjected to the impact of different human activities, and as a consequence, most of them are in a turbid state. Three types of shallow lakes have been described in this region: clear-vegetated, phytoplanktonturbid and inorganic-turbid. We analysed the periphyton and…
The room-temperature nitric acid (HNO3) compensation method is introduced to effectively improve the dielectric quality of ultrathin aluminum oxide (Al2O3) gate dielectrics under low thermal budget consideration. The physical properties, electrical characteristics, and temperature response of Al2O3 metal-oxide-semicon…
Failure of mechanically stabilized earth (MSE) walls attributed to the corrosion of galvanized steel in soil has raised concern on the adequacy of current design requirements. In this work, a numerical model was developed to calculate the corrosion rate of galvanized steel in soil at three different stages of corrosio…
Abstract Asphalt emulsions are a key material used for pavement preservation. Over time, asphalt concrete pavements become oxidized, which can lead to cracking and other surface deterioration. The addition of pavement maintenance treatments, such as scrub seals, chip seals, or fog seals, can rejuvenate the pavement su…
Plasmonic nanoparticles have traditionally been associated with relatively narrow absorption profiles. But, for many of the most exciting potential applications for these particles, such as solar energy applications, broadband absorption is desirable. By utilizing on-wire lithography, nanostructures which absorb light…
