Nano iğnelerin üretimi, yüksek performanslı çok işlevli nano cihazların geliştirilmesinde artan endüstriyel taleplerden dolayı ilgi çekmektedir. ölçekli uçlar kontrollü transdermal ilaç salımı, soğuk katot alan emisyonu, taramalı uç mikroskobu, yansıma önleyici kaplama ve nanoindentasyon uygulamalarında yaygın olarak kullanılmaktadır. Taramalı mikroskobu ailesinin bir üyesi olan Atomik kuvvet (...

In this paper, fabrication of silicon microchannels with integrated obstacles by using 25 wt.% tetramethylammonium hydroxide (TMAH) aqueous solution at the temperature 80?C is presented and analysed. We studied basic island patterns, which present union two symmetrical parallelograms sides along predetermined crystallographic directions <n10> (2<n<8) <100>. Acute angles were s...

Magnetite/gold core-shell nanoparticles (magnetite/gold NPs) have important optical and magnetic properties that provide potential for applications, especially biomedical ones. However, their preparation is not exempt from difficulties might lead to unexpected or undesired structures. This work reports the synthesis characterization of magnetite/gold NPs using tetramethylammonium hydroxide (TMA...

Graphene/silicon (Gr/Si) Schottky junction solar cells have attracted extensive research interest due to their simple structure and potential low-cost. Surface texturing is an important part of high-efficiency cells. In this paper, the effects TMAH concentration, IPA concentration etching time on anti-reflection ability silicon pyramid array (SiPa) were systematically studied obtain uniform rel...

An analytical method with no need for laborious sample preparation before determining the total Sn in canned tomatoes by hydride generation (HG) coupled to inductively plasma optical emission spectrometry (ICP OES) was developed. The ultrasound-assisted extraction various reagents (acidic media: HCl, HNO3, CH3COOH or aqua regia and alkaline: TMAH) that could replace traditional wet digestion pr...

Passivating contacts based on poly-Si have enabled record-high c-Si solar cell efficiencies due to their excellent surface passivation quality and carrier selectivity. The eventual existence of pinholes within the ultra-thin SiOx layer is one key factors for collection, beside tunneling mechanism. However, are usually believed negative impact passivating contacts. This work studied influence pi...
