Etching of glass microchips with supercritical water

28.10.2014 | P. Karásek; Jakub Grym; M. Roth; Josef Planeta; Frantisek Foret, Lab on a Chip, 2014

A novel method of etching channels in glass microchips with the most tunable solvent, water, was tested as an alternative to common hydrogen fluoride-containing etchants. The etching properties of water strongly depend on temperature and pressure, especially in the vicinity of the water critical ...

Manipulating and quantifying temperature-triggered coalescence with microcentrifugation

28.10.2014 | Huanhuan Feng; Dmitry Ershov; Thomas Krebs; Karin Schroen; Martien A. Cohen Stuart; Jasper van der Gucht; Joris Sprakel, Lab on a Chip, 2014

In this paper we describe a new approach to quantify the stability and coalescence kinetics of thermally switchable emulsions using an imaging-based microcentrifugation method. We first show that combining synchronized high-speed imaging with microfluidic centrifugation allows the direct ...

Gaseous titanium molybdates and tungstates: Thermodynamic properties and structures

24.10.2014 | Sergey I. Lopatin, Andrej I. Panin, Sergey M. Shugurov, Ksenia A. Emelyanova, Rapid Communications in Mass Spectrometry, 2014

RATIONALE Titanium is a component of various construction materials, which is often used at high temperature and in an oxidizing atmosphere. Thermally stable even at high temperatures, titanium compounds may appear in the condensed phase. To predict the possibility of existence of gaseous ...

Analytical techniques used for the characterization and authentification of six ancient religious manuscripts (XVIII–XIX centuries)

21.10.2014 | Nicoleta Vornicu, Viorica Deselnicu, Cristina Bibire, Daniela Ivanov, Florica Doroftei, Microscopy Research and Technique, 2014

ABSTRACT This article presents the experimental results of a research on six manuscripts (three of the XVIII century and three of XIX century) belonging collection of old religious books to the Moldovan Metropolitan Church of Romania. Non‐invasive techniques (optical microscopy [OM], scanning ...

Green synthesis of peptide-templated fluorescent copper nanoclusters for temperature sensing and cellular imaging

21.10.2014 | Hong Huang; hua Li; Ai-Jun Wang; Shuxian zhong; Keming Fang; Jiu-Ju Feng, Analyst, 2014

A simple and green approach was developed for preparation of fluorescent Cu nanoclusters (NCs) using artificial peptide CLEDNN as a template. The as-synthesized Cu NCs exhibited high fluorescence quantum yield (7.3%) and good stability, along with excitation and temperature dependent fluorescent ...

Sensors, Vol. 14, Pages 19493-19506: Novel Real-Time Temperature Diagnosis of Conventional Hot-Embossing Process Using an Ultrasonic Transducer

17.10.2014 | Cheng, Chin-Chi ; Yang, Sen-Yeu ; Lee, Dasheng, Sensors, 2014

This paper presents an integrated high temperature ultrasonic transducer (HTUT) on a sensor insert and its application for real-time diagnostics of the conventional hot embossing process to fabricate V-cut patterns. The sensor was directly deposited onto the sensor insert of the hot embossing ...

Sensors, Vol. 14, Pages 19517-19532: Gas Sensitivity and Sensing Mechanism Studies on Au-Doped TiO2 Nanotube Arrays for Detecting SF6 Decomposed Components

17.10.2014 | Zhang, Xiaoxing ; Yu, Lei ; Tie, Jing ; Dong, Xingchen, Sensors, 2014

The analysis to SF6 decomposed component gases is an efficient diagnostic approach to detect the partial discharge in gas-insulated switchgear (GIS) for the purpose of accessing the operating state of power equipment. This paper applied the Au-doped TiO2 nanotube array sensor (Au-TiO2 NTAs) to ...

Sensors, Vol. 14, Pages 19242-19259: High Resolution Switching Mode Inductance-to-Frequency Converter with Temperature Compensation

16.10.2014 | Matko, Vojko ; Milanović, Miro, Sensors, 2014

This article proposes a novel method for the temperature-compensated inductance-to-frequency converter with a single quartz crystal oscillating in the switching oscillating circuit to achieve better temperature stability of the converter. The novelty of this method lies in the switching-mode ...
