Molecular-dynamics simulations covering 30 ns of both a natural and a synthetic antimicrobial peptide in the presence of a zwitterionic lipid bilayer were performed. In both simulations, copies of the peptides were placed in an alpha-helical conformation on either side of the bilayer about 10 A (1 A=0.1 nm) from the interface, with either the hydrophobic or the positively charged face of the he...

Metasurfaces supply a planar approach for flexible wavefront manipulation, thus facilitating the integration and minimization of optical elements, especially in terahertz (THz) range. High efficient THz metadevices are highly pursued at present. Here, we propose bilayer design to improve efficiency metadevice. Two silicon pillar arrays with distinguishing geometries integrated on single substra...

Abstract Halide‐based solid electrolytes are currently growing in interest solid‐state batteries due to their high electrochemical stability window compared sulfide electrolytes. However, often a bilayer separator of and halide is used it unclear why such setup necessary, besides the instability halides against lithium metal. It shown that an electrolyte improves capacity retention as suppresse...

It is shown that potential barriers in bilayer graphene (BLG) and monolayer transition metal dichalcogenides (TMDs) can split a valley unpolarized incident current into reflected transmitted currents with opposite polarization. Valley asymmetric transmission inevitably occurs because of the low symmetry total Hamiltonian when external reflection 100% polarized BLG spin TMDs, except for exponent...

Alcohols are known modulators of lipid bilayer properties. Their biological effects have long been attributed to their bilayer-modifying effects, but alcohols can also alter protein function through direct protein interactions. This raises the question: Do alcohol's biological actions result predominantly from direct protein-alcohol interactions or from general changes in the membrane propertie...

Bilayer graphene has attracted wide attention due to its unique band structure and bandgap tunability under specific (Bernal or AB) stacking order. However, it remains challenging to tailor the stacking order and to simultaneously produce large-scale and high-quality bilayer graphene. This work introduces a fast and reliable method of growing high-quality Bernal stacked large-area (>3 in. × 3 i...

The knowledge of drug concentrations in bilayer headgroups, core, and at the interface between them is a prerequisite for quantitative modeling of drug interactions with many membrane-bound transporters, metabolizing enzymes and receptors, which have the binding sites located in the bilayer. This knowledge also helps understand the rates of trans-bilayer transport because balanced interactions ...

Bioelectronic devices such as neural stimulation and recording require stable low-impedance electrode interfaces. Various forms of nitridated titanium are used in biointerface applications due to robustness biological inertness. In this work, stoichiometric TiN thin films fabricated using a dual Kaufman ion-beam source setup, without the necessity substrate heating. These layers remarkable comp...

Complete determination of a membrane protein structure requires knowledge of the protein position within the lipid bilayer. As the number of determined structures of membrane proteins increases so does the need for computational methods which predict their position in the lipid bilayer. Here we present a coarse-grained molecular dynamics approach to lipid bilayer self-assembly around membrane p...

The patch clamp-liposome technique was used to examine the stretch sensitivity of a model membrane ion channel, gramicidin A, in membrane patches of different bilayer thickness. We found that small changes in phospholipid acyl chain length (i.e., PC-20 to PC-18) can switch gramicidin A from a stretch-activated to a stretch-inactivated channel. The demonstration that subnanometer changes in bila...
