Achieving higher carrier mobility plays a pivotal role for obtaining potentially high thermoelectric performance. In principle, the carrier mobility is governed by the band structure as well as by the carrier scattering mechanism. Here, we demonstrate that by manipulating the carrier scattering mechanism in n-type Mg3Sb2-based materials, a substantial improvement in carrier mobility, and hence ...

We investigated single crystals of GaN and thin film GaN radiation detectors by thermally stimulated currents and thermally stimulated depolarization methods in order to characterize carrier transport properties as influenced by material defect structure. In thick GaN no expressed structure of the thermally stimulated current spectra was observed in the temperature range from 100 K up to 350 K,...

background: wilson disease (wd) is caused by numerous pathogenic mutations of the atp7b gene. there are several mutation screening methods that can be used for the diagnosis and carrier detection of wd, however such methods are costly and time-consuming. therefore, other diagnostic methods should be used for urgent situations such as prenatal diagnosis. objective: to report common polymorphisms...

background: salmonella enterica serovar typhi (s. typhi) the cause of the acute febrile disease typhoid fever is the major public health problem in developing countries. asymptomatic carriers are the main sources of typhoid. the aim of this study was to investigate methods for isolation and identification of s. typhi in asymptomatic carriers. materials and methods: two hundred stool samples wer...

hepatitis delta virus (hdv) infection results in more severe and even fulminant form of hepatitis b in co-infected cases. this study was designed to estimate the prevalence of anti-hdv positivity and the associated risk factors in patients with chronic hepatitis b virus infection in zahedan (iran). in this cross-sectional study a total of 440 consecutive patients with chronic hepatitis b virus ...

introduction : staphylococcus aureus colonization has been recognized as one of the most important risk factors for subsequent infections with this microorganism. in this study, we intended to identify all patients who were mrsa-positive upon admission and compare the prevalence of mrsa colonization on different days of study admitted in imam reza hospital in mashhad, iran. methods : this cross...

We show how the maximum force principle can be derived from the holographic principle and vice versa, thus demonstrating equivalence of the two principles. Information is material, i.e. it always needs a material carrier. Information is impossible without matter. Let us consider some physical system of macroscopic dimensions , the Universe for example, different parts of which contain some info...

Michael S. Fuhrer, Chun Ning Lau, and Allan H. MacDonald carbide,7 which is emerging as a promising material for electronics applications, and is the subject of the review by First and co-authors in this issue. Several researchers have recently revisited the growth of graphene on metal surfaces8–10 and have developed techniques to transfer graphene from metals to insulating surfaces where elect...

in this study, feasibility of upgrading and retrofitting municipal wastewater treatment plantswas investigated at laboratory scale using moving bed biofilm reactor (mbbr) process. for this purpose,an aerobic pilot was operated for nearly one year in different conditions, in which a moving bed carrier with aspecific biofilm surface area of 500 m2/m3 and a filling rate of 60% was utilized. system...

Spatially resolved kinetic data of gallium–platinum SCALMS was captured while elucidating the effect carrier material on coke formation.
