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 ...


An adaptable stage perfusion incubator for the controlled cultivation of C2C12 myoblast cells

28.10.2014 | Felix Kurth; Alfredo Franco-Obregon; Christoph A Bärtschi; Petra S Dittrich, Analyst, 2014

Here we present a stage perfusion incubation system that allows for the cultivation of mammalian cells within PDMS microfluidic devices for long-term microscopic examination and analysis. The custom-built stage perfusion incubator is adaptable to any x-y microscope stage and is enabled for ...


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 ...


[Report] Room-temperature enantioselective C–H iodination via kinetic resolution

24.10.2014 | Ling Chu; Kai-Jiong Xiao; Jin-Quan Yu, Science , 2014

Palladium catalysis produces benzylamine derivatives of interest in medicinal chemistry. Authors: Ling Chu, Kai-Jiong Xiao, Jin-Quan Yu


Double Diffusive Magnetohydrodynamic (MHD) Mixed Convective Slip Flow along a Radiating Moving Vertical Flat Plate with Convective Boundary Condition

24.10.2014 | Mohammad M. Rashidi et al., PLoS ONE, 2014

by Mohammad M. Rashidi, Neda Kavyani, Shirley Abelman, Mohammed J. Uddin, Navid Freidoonimehr In this study combined heat and mass transfer by mixed convective flow along a moving vertical flat plate with hydrodynamic slip and thermal convective boundary condition is investigated. Using ...


Design of Finned Pipe Network to Improve Efficiency of Butter Melter

23.10.2014 | A.S. Warrier, I.K. Sawhney, P.S. Minz, Journal of Food Process Engineering, 2014

Abstract This study was undertaken to improve the efficiency of industrial butter melter. Butter is generally kept in cold storage at −18 to −20C in 20–25 kg blocks. Butter blocks are melted in a vat/kettle before being further processed or mixed with other food ingredients. The equipment ...


Novel Microelectrode-Based Online System for Monitoring N2O Gas Emissions during Wastewater Treatment

23.10.2014 | Ricardo Marques; Adrian Oehmen; Maite Pijuan, Environmental Science & Technology, 2014

Clark-type nitrous oxide (N2O) microelectrodes are commonly used for measuring dissolved N2O levels, but have not previously been tested for gas-phase applications, where the N2O emitted from wastewater systems can be directly quantified. In this study, N2O microelectrodes were tested and ...


Thermal Properties and Cellular Structure of Cornstarch‐Based Foams Formed by Extrusion Technology

22.10.2014 | Wai‐Bun Lui, Jinchyau Peng, Journal of Food Processing and Preservation, 2014

Abstract The aim of this work was to investigate the edible corn grit/PVOH (polyvinyl alcohol) blends of their thermal properties by using differential scanning calorimetry (DSC) and thermogravimetric analysis, and the average pore sizes and cellular structures of the blend foams were also ...


Sustainability, Vol. 6, Pages 7263-7275: Wireless Sensor Network Powered by a Terrestrial Microbial Fuel Cell as a Sustainable Land Monitoring Energy System

22.10.2014 | Pietrelli, Andrea ; Micangeli, Andrea ; Ferrara, Vincenzo ; Raffi, Alessandro, Sustainability, 2014

This work aims at investigating the possibility of a wireless sensor network powered by an energy harvesting technology, such as a microbial fuel cell (MFC). An MFC is a bioreactor that transforms energy stored in chemical bonds of organic compounds into electrical energy. This process takes ...
