Sensors, Vol. 13, Pages 12192-12217: Fast Thermal Calibration of Low-Grade Inertial Sensors and Inertial Measurement Units

12.09.2013 | Niu, Xiaoji ; Li, You ; Zhang, Hongping ; Wang, Qingjiang ; Ban, Yalong, Sensors, 2013

The errors of low-cost inertial sensors, especially Micro-Electro Mechanical Systems (MEMS) ones, are highly dependent on environmental conditions such as the temperature. Thus, there is a need for the development of accurate and reliable thermal compensation models to reduce the impact of such ...

Effect of the Fast Pyrolysis Temperature on the Primary and Secondary Products of Lignin

11.09.2013 | Shuai Zhou; Manuel Garcia-Perez; Brennan Pecha; Sascha R. A. Kersten; Armando G. McDonald; Roel J. M. Westerhof, Energy & Fuels, 2013

This paper presents results on the primary pyrolysis products of organosolv lignin at temperatures between 360 and 700 °C. To study the primary products, a vacuum screen heater (heating rate of 8000 °C/s, deep vacuum of 0.7 mbar, and very fast cooling at the wall temperature of −100 °C) was used. ...

DNA Release: Sharpening the Thermal Release of DNA from Nanoparticles: Towards a Sequential Release Strategy (Small 17/2013)

03.09.2013 | Julián A. Díaz, Julianne M. Gibbs‐Davis, Small, 2013

Two branched DNA structures with different stabilities are hybridized with DNA‐modified gold nanoparticles. As J. A. Díaz and J. M. Gibbs‐Davis report on page 2862, in contrast to linear DNA, these branched DNA structures dissociate over a narrow temperature window. Consequently, the less ...

Ribose‐Induced Maillard Reaction as a Quality Index in Frozen Minced Chicken and Pork Meats

03.09.2013 | Thuan‐Chew Tan, Abbas F.M. Alkarkhi, Azhar Mat Easa, Journal of Food Quality, 2013

Abstract Minced meats underwent denaturation, oxidation and aggregation during frozen storage, causing decrease in denaturation enthalpy, sulfhydryl contents and protein solubility, as well as increase in protein carbonyl and disulfide contents. These changes were more evident in samples ...

Molecular Tensile Machines: Anti-Arrhenius Cleavage of Disulfide Bonds

03.09.2013 | Yuanchao Li; Alper Nese; Krzysztof Matyjaszewski; Sergei S. Sheiko, Macromolecules, 2013

Molecular tensile machines are bottlebrush molecules where tension along the backbone is self-generated due to steric repulsion between the densely grafted side chains. Upon adsorption onto a substrate, this intrinsic tension is amplified to the nanonewton range depending on the side chain ...
