While the use of plastics continues to increase in our daily lives in a growing range products, these materials are very persistent in the environment. The blending of aliphatic polyesters with other thermoplastic polymers is a profitable way of producing materials with changed physical properties and biodegradability…
Graphene with varying number of layers is explored as metal gate electrode in metal oxide semiconductor structure by inserting it between the dielectric (SiO2) and contact metal (TiN) and results are compared with TiN gate electrode. We demonstrate an effective work function tuning of gate electrode upto 0.5 eV by var…
This study investigated the effect of the relative humidity (RH) and density of unidirectional oriented strand board (OSB) on parallel, perpendicular and through-the-thickness elastic modulus (E1, E2 and E3) and interlaminar shear modulus (G13 and G23). The relationships between these parameters and density were deter…
The identification of structure-function relationships in allosteric enzymes is essential to describing a molecular mechanism for allosteric processes. The enzyme α-isopropylmalate synthase from Mycobacterium tuberculosis (MtIPMS) is subject to slow-onset, allosteric inhibition by l-leucine. Here we report that altern…
We performed an ab initio investigation on the properties of rutile tin oxide (SnO x ) nanowires. We computed the wire properties determining the equilibrium geometries, binding energies, and electronic band structures for several wire dimensions and surface facet configurations. The results allowed us to establish sc…
Based on the fundamental Le Chatellier principle, gas producing reactions can be pushed at lower temperatures if an appropriate vacuum is applied. A basic thermodynamic analysis is used to predict the effect of pressure decrease on the temperature and exergy cost of a reaction with gaseous products. The energy analysi…
In soil application, o,o-FeEDDHA (iron (3+) ethylene diamine-N,N'-bis(2-hydroxy phenyl acetic acid) complex) is the active ingredient of FeEDDHA chelate-based Fe fertilizers. The effectiveness of o,o-FeEDDHA is potentially compromised by the displacement of Fe from FeEDDHA by Cu. The actual impact of Cu competition is…
Abstract Water-based drilling fluids consisting of xanthan gum, starch, sized calcium carbonate and salt particles have been used to drill horizontal wells. Available chemical methods of removing filter cake like mineral acids, esters, oxidizers, and chelating agents are limited at certain conditions. Drilling fluid w…
We present realistic multiband calculations of scanning tunneling spectra in Bi${}_{2}$Sr${}_{2}$CaCu${}_{2}$O${}_{8+\ensuremath{\delta}}$ over a wide doping range. Our modeling incorporates effects of a competing pseudogap and pairing gap as well as effects of strong electronic correlations, which are included by int…
A stimuli-response biological surface of L-cysteine was prepared on a polycrystalline gold surface from aqueous solution. The effect of the pH value of the rinsing solution on the surface composition was studied with X-ray photoelectron spectroscopy (XPS). Qualitative and quantitative analysis of the amino, carboxyl,…
We present a novel method for synthesizing epitaxial quantum dot-nanowire (QD-NW) heterostructures using the example of colloidal PbSe QDs decorated on furnace-grown hematite (α-Fe2O3) NWs. The direct heterogeneous nucleation of QDs on Fe2O3 NWs relies upon an aggressive surface dehydration of the as-synthesized Fe2O3…
A shift in bond: The difference between Hartree–Fock and CI energies of isodesmic reactions serves as a tool for identifying charge-shift bonds.
We investigated silver nanowires using correlative wide-field fluorescence and transmission electron microscopy. In the wide-field fluorescence images, synchronous emission from different distinct positions along the silver nanowires was observed. The sites of emission were separated spatially by up to several microme…
In this study, a novel structure using a sandwiched CuGa/CuInGa/In precursor layer is employed for improving the Voc and Jsc of a CIGS solar cell. The addition of a CuGa layer on the surface of CuInGa precursor enhanced the Ga concentration in the space charge region and thus enhanced the Voc by about 18.2%. The addit…
Abstract Copper(I) catalyzed azide‐alkyne 1,3‐Huisgen cycloaddition reaction afforded the synthesis of triazole‐containing polyesters and segmented block copolyesters at moderate temperatures. Triazole‐containing homopolyesters exhibited significantly increased (∼40 °C) glass transition temperatures (Tg) relative to h…
The postspinel mineral MgAl(2)O(4) exists only under the severe pressure conditions in the subducted oceanic lithosphere in the Earth's deep interior. Here we report that its analogous oxide CdRh(2)O(4) exhibits a structural transition to a quenchable postspinel phase under a high pressure of 6 GPa at 1400 °C, which i…
Abstract An essential prerequisite for a sustainable soil use is to maintain a satisfactory soil organic‐matter (OM) level. This might be achieved by sound fertilization management, though impacts of fertilization on OM have been rarely investigated with the aid of physical fractionation techniques in semiarid regions…
The temperature and field dependent leakage current in HfO2/SiO2 gate stack for in situ steam grown and chemical interfacial layers (ILs) are studied in the temperature range of 20 °C to 105 °C. Poole-Frenkel mechanism in high field whereas Ohmic conduction in low field region are dominant for both devices. Leakage cu…
The electrophoretic deposition (EPD) method has been developed for the fabrication of MnO(2)-multiwalled carbon nanotube (MWCNT) films for application in electrochemical supercapacitors (ESs). For MWCNT applications, which depend on electrical conductivity, it is challenging to achieve dispersion and EPD of pristine M…
We investigated an old dogma, namely, that aromatic self-assembled monolayers (SAMs) are cross-linked and stabilized by irradiation with electrons, whereas aliphatic SAMs on the same substrate are degraded under the same conditions. To this end, we prepared SAMs of novel cycloaliphatic molecules (4-cyclohexylcyclohexa…
