Graphene films grown on metal substrates by chemical vapor deposition (CVD) method have to be safely transferred onto desired for further applications. Recently, a roll-to-roll (R2R) has been developed large-area transfer, which is particularly efficient flexible target substrates. However, in the case of rigid such as glass or wafers, roll-based found induce considerable mechanical damages graphene during transfer process, resulting degradation electrical property. Here we introduce an...
In this study, we develop an ultra-fast fiber Bragg grating sensor system that is based on the Fourier domain mode-locked (FDML) swept laser. A FDML wavelength laser has many advantages compared to conventional source, such as high-speed interrogation, narrow spectral sensitivity, and high phase stability. The newly developed shows a superior performance of scan rate 31.3 kHz broad range over 70 nm simultaneously. interrogating using characterized in both static dynamic strain responses.
Abstract Water purification by membranes is widely investigated to address concerns related the scarcity of clean water. Achieving high flux and rejection simultaneously a difficult challenge using such because these properties are mutually exclusive in common artificial membranes. Nature has developed method for this task involving water‐channel membrane proteins known as aquaporins. Here, design fabrication graphene oxide (GO)‐based with surface‐tethered peptide motif designed mimic...
Abstract Molecular dynamics (MD) simulation is an important tool for understanding protein and the thermodynamic properties of proteins. However, due to high computational cost MD simulations, it still challenging explore a wide conformational space. To solve this problem, variety accelerated (aMD) schemes have been proposed over past few decades. The bond‐boost method (BBM) one such aMD schemes, which expedites escape events from energy basins by adding bias potential based on changes in...
This study investigates the thermodynamic parameters of 1300 RNA/DNA hybrid duplexes, including both natural and chemically modified forms, using molecular dynamics (MD) simulations. Modified duplexes consist phosphorothioate (PS) backbones 2'-O-methoxyethyl (MOE) modifications, commonly used in therapeutic oligonucleotides. Hybridization enthalpy entropy were calculated from MD trajectories mechanics Poisson-Boltzmann surface area (MMPBSA) generalized Born (MMGBSA) approaches. To address...
Abstract Healable conductive materials have received considerable attention. However, their practical applications are impeded by low electrical conductivity and irreversible degradation after breaking/healing cycles. Here we report a highly completely reversible electron tunneling-assisted percolation network of silver nanosatellite particles for putty-like moldable healable nanocomposites. The densely uniformly distributed with bimodal size distribution generated the radical reactive...
Graphene is known as a superstiff and extremely strong material. Hence, applying strains greater than 1% to graphene simultaneously measuring changes in its physical properties has been challenging because of the limited methodologies for both high strain other properties. Here, Raman scattering measurement suspended under biaxial large 6.1% using an atomic force microscopy (AFM)-Raman spectroscopy tool reported. Nanoindentation performed AFM tips machined have flat top hole shape, resulting...
Abstract Ionic liquids (ILs) are considered to be green solvents because of their non-volatility. Although ILs relatively safe in the atmospheric environment, they may toxic other environments. Our previous research showed that cytotoxicity biological organisms is attributable interference with cell membranes by IL insertion. However, effects on ion channels, which play important roles homeostasis, have not been comprehensively studied date. In this work, we interactions between and lipid...
An elastic network model (ENM), usually Cα coarse-grained one, has been widely used to study protein dynamics as an alternative classical molecular simulation. This simple approach dramatically saves the computational cost, but sometimes fails describe a feasible conformational change due unrealistically excessive spring connections. To overcome this limitation, we propose mass-weighted chemical (MWCENM) in which total mass of each residue is assumed be concentrated on representative alpha...
The information capacity of double-crossover (DX) tiles was successfully increased beyond a binary representation to higher base representations. By controlling the length and position DNA hairpins on DX tile, ternary senary (base-3 base-6) digit representations were realized verified by atomic force microscopy (AFM). Also, normal mode analysis (NMA) carried out study mechanical characteristics each structure.
Although high optical illumination power is favored in coherence tomography (OCT) for better signal-to-noise ratio, often limited by a damaged threshold biomedical living tissues and autocorrelation signals observed tomograms. In order to improve signal sensitivity without increasing the power, spectrally sampled multi-wavelength light source proposed OCT system. A fiber Sagnac comb filter was used sample output of continuous spectral source. Point spread function analysis shows that has an...
