Amorphous magnesium silicide
(ELSEVIER, RADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2018)
A first principles molecular dynamics technique is employed to generate an amorphous magnesium silicide (Mg2Si) model from its liquid state and its structural, electrical and mechanical features are disclosed for the first ...
Amorphous zirconia at high pressure
(WILEY, 111 RIVER ST, HOBOKEN 07030-5774, NJ USA, 2018)
We show, by means of ab initio calculations, that amorphous zirconia progressively transforms to a high-density amorphous phase with the application of pressure. The average coordination number of Zr and O atoms under ...
Transmitter Localization in Vessel-Like Diffusive Channels Using Ring-Shaped Molecular Receivers
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 445 HOES LANE, PISCATAWAY, NJ 08855-4141 USA, 2018)
Molecular communication via diffusion in vessellike environment targets critical applications such as the detection of abnormal and unhealthy cells. In this letter, we derive the analytical formulation of the channel model ...
Synthesis of polyketone-g-vinylbenzyl chloride anion exchange membrane via irradiation and its properties
(POLYMER SOC KOREAROOM 601, HATCHON BUILDING, 831 YEOKSAM-DONG, KANGNAM-KU, SEOUL 135-792, SOUTH KOREA, 2017)
A novel anion exchange membrane composed of aminated polyketone-g-vinylbenzyl chloride was synthesized via Co-60 gamma-ray irradiation grafting technique. Total irradiation dose and concentration of monomers were set as ...
Nanostructured organic semiconductor films for molecular detection with surface-enhanced Raman spectroscopy
(NATURE RESEARCHHEIDELBERGER PLATZ 3, BERLIN 14197, GERMANY, 2017)
pi-Conjugated organic semiconductors have been explored in several optoelectronic devices, yet their use in molecular detection as surface-enhanced Raman spectroscopy (SERS)-active platforms is unknown. Herein, we demonstrate ...
Protein beta-sheet prediction using an efficient dynamic programming algorithm
(ELSEVIER SCI LTDTHE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2017)
Predicting the beta-sheet structure of a protein is one of the most important intermediate steps towards the identification of its tertiary structure. However, it is regarded as the primary bottleneck due to the presence ...
Two successive amorphous-to-amorphous phase transformations in TiO2
(WILEY111 RIVER ST, HOBOKEN 07030-5774, NJ, 2017)
Based on constant pressure ab initio simulations, we propose, for the first time, two successive amorphous-to-amorphous phase transformations for TiO2. The first one is a gradual phase transformation from a low-density ...
A design method of comb-drive actuators for linear tuning characteristics in mechanically tunable optical filters
(SPRINGER HEIDELBERGTIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY, 2017)
A new method is proposed in design of comb-drive actuators for specific voltage-displacement characteristics with finger gaps as the design parameters. The design method proposed by the author previously is further refined ...
Densification of amorphous boron under pressure
(ELSEVIERRADARWEG 29, 1043 NX AMSTERDAM, NETHERLANDS, 2017)
The densification mechanism of amorphous boron under pressure is investigated using a constant pressure ab initio technique and found to be associated with two consecutive amorphous-to-amorphous phase transformations. ...
Ferromagnetism in amorphous MgO
(TAYLOR & FRANCIS LTD2-4 PARK SQUARE, MILTON PARK, ABINGDON OR14 4RN, OXON, ENGLAND, 2017)
We report, for the first time, the atomic structure of amorphous MgO based on ab initio molecular dynamics simulations. We find that its main building blocks are four-fold and five-fold coordinated configurations, similar ...
