Graphite as one alotrof carbon is widely used as an electrode material for a good electrical conductivity properties. Charcoal as a carbon source material was found very abundant in nature. Charcoal has the potential application for electrode material in energy storage such as in a battery or supercapacitor. For this…
Salah satu cara meningkatkan keakurasian dimensi dengan cara membuat cetakan yang mempunyai saluran pendingin yang merata, mengikuti kontur dari cavity, sehingga arah penyusutan produk pada siklus pendinginan dapat merata. Mold tipe solid yang selama ini digunakan mempunyai keterbatasan pada sistim saluran pendinginan…
In this work, we describe a new 3-dimensional (3D) network of crosslinked Horseradish Peroxidase/Carbon Nanotube (HRP/CNT) on a thiol-modified Au surface in order to build up the effective electrical wiring of the enzyme units with the electrode. This is achieved by the electropolymerization of aniline-functionalized…
В работе исследуются механические свойства композиции сталей 08кп и У8, состоящей из 100 и 2500 чередующихся слоев, анализируется зависимость свойств от температуры нагрева перед прокаткой. Технология получения многослойных листов с устойчивой ультрамелкозернистой структурой основана на многократной горячей прокатке з…
T study is to predict heating and melting of a workpiece with a self-consistent, deformable free surface subject to a surface plasmon induced by a pulsed laser in TM mode. A surface plasmon on a metal surface can be excited by an incident laser beam in a TM mode, representing that magnetic field is perpendicular to th…
P integrated system depends on an ability to develop various compact optical components and facilities their integration on a common substrate. Of course, there are many photonic integrated circuit components that have not been realized due to their complexity or certain difficulties in processing. In this regard, nat…
Preprints is a multidisciplinary preprint platform that accepts articles from all fields of science and technology, given that the preprint is scientifically sound and can be considered part of academic literature.
Calculations of the vibrational properties of the transition-metal dichalcoginides depend critically on the lattice parameters, symmetries of the underlying system, and the non-local dispersive interaction. Here we present phonon band structure calculations, dielectric tensors, elastic tensors, and Born Effective Char…
In this paper, the effects of reinforcing and matrix material on the mechanical properties of composites were investigated. Carbon fibre (CF) and glass fibre (GF) are the most useful reinforcement materials in polymer-based composites, their major use being the manufacture of components in the aerospace, automotive an…
We report the dynamics of soft phonon modes and their role in the structural phase transitions of the Aurivillius materials studied by employing terahertz frequency-domain spectroscopy, atomic pair distribution function analysis, and first-principles calculations. We have chosen Bi4Ti3O12 as a model system and discove…
Actuators at the nanoscale are assuming great important in todays shrinking electronics industry where a system-on-chip approach is used to integrate multi-functional systems and devices. Integration of sensors, actuators, information processing, and storage have become extremely important, more so at the sub-micromet…

Fatigue crack growth behavior of nanocrystalline copper with grain size less than 250 nm is studied and compared to its microcrystalline counterpart.The nanocrystalline samples are prepared by processing commercially pure Cu using the equal channel angular extrusion (ECAE) process.The microcrystalline samples are prep…
Abstract As the key component of SOFC (solid oxide fuel cell), a theoretical framework has been built to illustrate the coupling effect between oxygen vacancy concentration and stress field in early works. Here, the coupling theory is expanded and more affecting factors are taken into consideration. An electrolyte mem…
In the paper by K. Rajput and S. Vitta published in the present journal the synthesis and the thermoelectric properties of the dysprosium containing clathrate Dy 8 Al 16 Si 30 were reported. We prepared two samples following exactly to the technique described in the paper. Our XRD and SEM/EDX investigations do not con…
Baja C-Mn adalah baja hasil proses perlakuan panas yang dapat dikembangkan menjadi baja tahan aus dengan proses quenching dan tempering. Permasalahan yang mendasari dalam penelitian ini adalah: Apa perubahan yang terjadi pada baja C-Mn setelah dilakukan proses quenching dan tempering?.Tujuan dalam penelitian ini adala…

Количественный анализ эффекта упрочнения матрицы композита наноструктурными элементами затруднен значительным разбросом теоретических и экспериментальных данных о механических свойствах таких элементов, в том числе об упругих характеристиках углеродных нанотрубок, особенно многослойных. В данной работе представлены дв…
В работе рассмотрен вопрос стабилизации ротора искусственного желудочка сердца (ИЖС). Актуальность исследований в этой области обусловлена увеличением числа больных, страдающих сердечной недостаточностью (по данным ежегодной конференции Общества специалистов по СН). Глобальным аспектом при проектировании устройств ИЖС…
Cyclic tests were conducted on unidirectional carbon-epoxy composite specimens loaded at 45oto the fibre axis, using a stress ratio R (minimum/maximum stress)of 0.1. Matrix damage wasmonitored through measuring strain changes in the direction perpendicular to the fibres and inthe loading and transverse directions. Hys…
