Enhanced etching characteristics of Si{100} in NaOH-based two-component solutionMicro and Nano Systems Letters - Tập 10 - Trang 1-8 - 2022
V. Swarnalatha, S. Purohit, P. Pal, R. K. Sharma
Silicon wet bulk micromachining is the most widely used technique for the
fabrication of diverse microstructures such as cantilevers, cavities, etc. in
laboratory as well as in industry for micro-electromechanical system (MEMS)
application. Although, increasing the throughput remains inevitable, and can be
done by increasing the etching rate. Furthermore, freestanding structure release
time can be... hiện toàn bộ
Development of an amperometric sensor for epinephrine determination using an Azure A/silver nanocluster modified electrodeMicro and Nano Systems Letters - Tập 11 Số 1
C. Priya, S. Anuja, R. Suresh Babu, S. Sriman Narayanan
AbstractA novel electrochemical sensor was developed for the detection of
Epinephrine (EP) utilizing Azure A (AzA), a phenothiazine dye, and
citrate-capped silver nanoparticles. The interaction between Azure A and silver
nanoparticles facilitated the formation of AzA/silver nanoclusters through a
self-assembled approach. The morphological analysis of AzA/silver nanoclusters
was conducted using fie... hiện toàn bộ
Analysis of liquid-type proof mass under oscillating conditionsMicro and Nano Systems Letters - Tập 8 - Trang 1-7 - 2020
Dong-Joon Won, Sangmin Lee, Joonwon Kim
In this study, the spring constant of an accelerometer with a liquid-type proof
mass was analyzed. Unlike a general solid-type microelectromechanical system
accelerometer, the Laplace pressure is considered a restoring force in the
analyzed accelerometer. Using a base excitation mathematical model, the sensor
output could be estimated for a specific spring constant. Although the estimated
sensor o... hiện toàn bộ
Simple refractometry using optical path separation via multiple pinholesMicro and Nano Systems Letters - Tập 5 - Trang 1-6 - 2017
Sang Youl Yoon, Ji-chul Hyun, Sung Yang
We herein report on a simple and novel method of refractometry that uses a micro
image defocusing technique. This simple method makes use of a three-pinhole
aperture attached to a microscopic optical system. In order to develop our
proposed method, an analytical formula was derived from the principles of
optical modelling, taking into consideration imaging optics, and was verified
experimentally. ... hiện toàn bộ
Synthesis of metallic aluminum particles by electrolysis in aqueous solutionMicro and Nano Systems Letters - - 2021
Takefumi Hosoya, Tadashi Yonezawa, Noriko Yamauchi, Kouichi Nakashima, Yoshio Kobayashi
AbstractThe present work proposes a method for fabricating metallic Al particles
in aqueous solution. An aqueous colloidal solution was prepared from an aqueous
aluminum nitrate nonahydrate solution by electrolysis using metallic Al plates
as the anode and cathode under ultrasonic irradiation in water at 25–45 °C. The
sizes of the particles in the colloidal solutions prepared at 25, 35, and 45 °C

Development of a fully automated desktop chemical vapor deposition system for programmable and controlled carbon nanotube growthMicro and Nano Systems Letters - Tập 7 - Trang 1-8 - 2019
Ju Hyun Ahn, Minho Na, Sungkwan Koo, Hyunsoo Chun, Inhwan Kim, Jong Won Hur, Jae Hyuk Lee, Jong G. Ok
We have rationally designed and developed a fully automated desktop furnace
system that enables programmable chemical vapour deposition growth of carbon
nanotubes with controlled height, density, and pattern architecture. Comprising
several essential components involving a heating furnace, mass flowmeters, and
computer controller, the developed system realizes controlled and practical

The influence of resistance and carrier concentration on the output voltage of a ZnO nanogeneratorMicro and Nano Systems Letters - Tập 1 - Trang 1-6 - 2013
Thomas S van den Heever, Willem J Perold
Zinc oxide (ZnO) nanowires were synthesised through two different methods; the
vapour liquid solid (VLS) method and an aqueous solution method. Each method had
its own set of parameters and changes in those parameters influenced the output
voltage of a nanogenerator. Changes in output voltage occurred as a result of
variations in the resistance and the carrier concentration of grown nanowires as
