The voltage-gated proton channel (Hv1) is homologous to the voltage-sensing domain (VSD) of voltage-gated potassium (Kv) channels but lacks a separate pore domain. The Hv1 monomer has dual functions: it gates the proton current and also serves as the proton conduction pathway. To gain insight into the structure and dynamics of the yet unresolved proton permeation pathway, we performed all-atom ...

Understanding the transport characteristics at atomic limit is prerequisite for futuristic nanoelectronic applications. Among various experimental procedures, mechanically controllable break junction (MCBJ) a well-adopted technique to study and control or molecular scale devices. Here, we present details of developing piezo-controlled table-top MCBJ set-up, working ambient conditions, along wit...

DNA codons, consisting of triplet nucleotides (NTs), could play important roles for RNA transcription and protein translation in living systems. Therefore, their recognition be seen diagnosis therapy purposes. Based on sequence formations Adenine (A), Guanine (G), Cytosine (C) Thymine (T) NTs, 64 codons were investigated this work regarding complexation with a molecular cubane (CUB) wire. To ac...

background: the aim of this study was to evaluate the response of common sized fiber-reinforced composites (frcs) to different deflections due to bending forces and comparing it with stainless steel (ss) wires. materials and methods: in this experimental study, two frc groups with 0.75 mm and 1.2 mm diameters (everstick ortho, stick tech, finland) and three ss groups with 0.016 × 0.022 inch, 0....

this paper presents a new method called vespiary regular hexagonal (vrh) model to calculate parasitic capacitance between conductor wire filaments of one turn of a coil and between conductor wires filament and liner and also total capacitance of n-turns having single-layers, multi-conductor wire filaments of the helix magneto cumulative generator (mcg) coil. the presented method is an analytica...

The synthesis of hexagonal wurzite one-dimensional (1D) GaN nanostructures on c-Al2O3 substrates was investigated using a thermal chemical vapor deposition (CVD) process. The diameter of the GaN nanostructures was controlled by varying the growth time using a mixture of GaN powder and Ga metal with the ammonia gas reaction. The morphologies of the GaN nanowires and nanorods were confirmed by fi...

Measurements of electron transfer rates as well as of charge transport characteristics in DNA produced a number of seemingly contradictory results, ranging from insulating behaviour to the suggestion that DNA is an efficient medium for charge transport. Among other factors, environmental effects appear to play a crucial role in determining the effectivity of charge propagation along the double ...

According to the predictions of Gordon Moore in 1965, the number of transistors per square centimeter of silicon doubles every 18 months [1]. This requires that the size of transistors and the interconnecting wires between them decrease at the same rate. Up until now, this miniaturization has been realized by improvements in photolithographic techniques. These techniques will reach their fundam...

We use an atomistic tight-binding theory to study arrays of T-shaped GaAs/AlGaAs quantum wires. An atomistic approach allows us to provide a theory of the electron and hole states in T shaped wires without the approximations that limit effective mass models. We calculate the band structure of electron and holes in periodic T-wire arrays and in arm wells and compare with the results of effective...

We investigate transport through molecular wires whose energy levels are affected by environmental fluctuations. We assume that the relevant fluctuations are so slow that they, within a tight-binding description, can be described by disordered, Gaussian distributed onsite energies. For long wires, we find that the corresponding current distribution can be rather broad even for a small energy va...
