Electric field induced phase transitions of confined water have an important role in cryopreservation and electrocrystallization. In this study, the structural and dynamical properties of nano-confined water in nano-slit pores under the influence of an electric field varying from 0 to 10 V nm(-1) are investigated under ambient conditions using molecular dynamics simulations. In order to replica...
Abstract In this review, we engineer a high-performing nanosensor mechanic based on SPPs, which consists of metal-insulator-metal waveguide coupled with two triangular plates in double-internal-pile ring cavity (DISRC). The feasibility establishing the sensor SPPs is analyzed theoretically, and parameters DISRC are simulated by finite element method. best sensitivity proposed system 2640 nm/RIU...
فرآیند ماشینکاری به روش تخلیه الکتریکی( edm)، یکی از فرآیندهای نوین ماشینکاری است که کاربردهای متنوعی در ساخت و تولید محصولات میکرومتری دارد. رشد و توسعه نانوتکنولوژی و نیاز به بهره گیری از روشهای جدید موجب شده است که جذبه زیادی برای استفاده از فرآیند edm در ساخت و تولید محصولات نانومتری ایجاد شود. فرآیند nano-edm یک فرآیند ماشینکاری حرارتی است که در آن از انرژی حرارتی حاصل از جرقه الکتریکی برا...

This chapter provides a general description of a variational graph-theoretic formulation for simulation of flexible multibody systems (FMS) which includes a brief review of linear graph principles required to formulate this algorithm. The system is represented by a linear graph, in which nodes represent reference frames on flexible bodies, and edges represent components that connect these frame...
INTRODUCTION: Our inability to record single cell activity with high resolution over a long period of time precludes fundamental understanding of nervous system functions, both under normal and pathological conditions. While the fabrication of current microand nano-electrodes has advanced our capabilities to perform long-term recordings, this has been at the expense of signal resolution due to ...
Uniform arrays of nano-sized pore produced in porous alumina were transferred into InP substrates by inductively coupled plasma reactive ion etching (ICP-RIE). We observed a significant enhancement in the light output from InP substrate with nanohole arrays on the surface. Photoluminescence intensity of triangular arrays of air cylinders on InP substrate showed an enhancement up to 3 times comp...
The self-assembly of colloidal particles is a route to designed materials production that combines high flexibility, cost effectiveness, and the opportunity to create ordered structures at length scales ranging from nano- to micrometers. For many practical applications in electronics, photovoltaics, and biomimetic material synthesis, ordered mono- and bilayers are often needed. Here we present ...
ZnO nanostructures were synthesized by hydrothermal method using different molar ratios of cetyltrimethylammonium bromide (CTAB) and Sodium dodecyl sulfate (SDS) as structure directing agents. The effect of surfactants on the morphology of the ZnO crystals was investigated by field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) techniques. The results i...
در این مطالعه، فرمولاسیون¬های نانوی نور تخریب¬پذیر و زیست¬سازگار ایمیداکلوپرید و ایندوکساکارب، به واسطه¬ی کپسوله کردن مستقیم هر کدام ازآنها با کوپلیمرهای خطی- دندریتیک پلی¬سیتریک¬اسید-پلی¬اتیلن¬گلیکول-پلی¬سیتریک¬اسید (pca-peg-pca) تهیه شدند. سنتز این نانوآفت¬کش¬ها به دو صورت بدون کاربرد نانوذرات tio2 (nano-ind و nano-imi) و با کاربرد نانوذرات tio2 (nano-ind/tio2 و nano-imi/tio2) انجام شد. فرمول...
