Thermal activation of catalytic microjets in blood samples using microfluidic chips

18.09.2013 | Lluis Soler; Cynthia S Martinez-Cisneros; Anka Swiersy; Samuel Sanchez; Oliver G. Schmidt, Lab on a Chip, 2013

We demonstrate that catalytic microjet engines can out-swim high complex media composed by red blood cells and serum. Despite the challenge presented by the high viscosity of the solution at room temperature, the catalytic microjets can be activated at physiological temperature and, consequently, ...

Comparative LC-MS/MS analysis of Optimal Cutting Temperature (OCT) compound removal for the study of mammalian proteomes

17.09.2013 | Leigh A. Weston; Amanda Hummon, Analyst, 2013

Primary tissue samples are valuable resources for investigators interested in understanding disease. In order to maximize the information content that can be gained from these precious samples, proper storage, handling, and preparation are essential. Some tissue preservation techniques utilize ...

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 ...

Metal–organic frameworks: a novel SERS substrate

11.09.2013 | Tsung‐Han Yu, Chin‐Hsian Ho, Cheng‐You Wu, Ching‐Hsuan Chien, Chia‐Her Lin, Szetsen Lee, Journal of Raman Spectroscopy, 2013

We report the direct observation of surface‐enhanced Raman scattering (SERS) effect using metal–organic frameworks (MOFs) as substrates. Without the aid of any metal colloids or enhancing agents, the SERS signals of methyl orange (MO) adsorbed in MOFs were observed and even remained active if ...

3D Structures of Liquid-Phase GaIn Alloy Embedded in PDMS with Freeze Casting

11.09.2013 | Andrew Fassler; Carmel Majidi, Lab on a Chip, 2013

Liquid phase electronic circuits are created by freeze casting gallium-indium (GaIn) alloys, such as eutectic gallium-indium (EGaIn), and encapsulating these frozen components within an elastomer. These metal alloys are liquid at room temperature, and can be cast using either injection or a ...

Sensors, Vol. 13, Pages 12166-12174: Temperature Stability of the Sky Quality Meter

11.09.2013 | Schnitt, Sabrina ; Ruhtz, Thomas ; Fischer, Jürgen ; Hölker, Franz ; Kyba, Christopher C.M., Sensors, 2013

The stability of radiance measurements taken by the Sky Quality Meter (SQM)was tested under rapidly changing temperature conditions during exposure to a stable lightfield in the laboratory. The reported radiance was found to be negatively correlated withtemperature, but remained within 7% of the ...

Sensors, Vol. 13, Pages 12113-12131: Improving Pyroelectric Energy Harvesting Using a Sandblast Etching Technique

10.09.2013 | Hsiao, Chun-Ching ; Siao, An-Shen, Sensors, 2013

Large amounts of low-grade heat are emitted by various industries and exhausted into the environment. This heat energy can be used as a free source for pyroelectric power generation. A three-dimensional pattern helps to improve the temperature variation rates in pyroelectric elements by means of ...

Sensors, Vol. 13, Pages 11956-11968: Characterization of Flexible Copolymer Optical Fibers for Force Sensing Applications

09.09.2013 | Krehel, Marek ; Rossi, René M.; Bona, Gian-Luca ; Scherer, Lukas J., Sensors, 2013

In this paper, different polymer optical fibres for applications in force sensing systems in textile fabrics are reported. The proposed method is based on the deflection of the light in fibre waveguides. Applying a force on the fibre changes the geometry and affects the wave guiding properties ...

Sensors, Vol. 13, Pages 12012-12029: Practical Strategies for Stable Operation of HFF-QCM in Continuous Air Flow

09.09.2013 | Wessels, Alexander ; Klöckner, Bernhard ; Siering, Carsten ; Waldvogel, Siegfried R., Sensors, 2013

Currently there are a few fields of application using quartz crystal microbalances (QCM). Because of environmental conditions and insufficient resolution of the microbalance, chemical sensing of volatile organic compounds in an open system was as yet not possible. In this study we present ...

Embryonic development of chicken (Gallus Gallus Domesticus) from 1st to 19th day—ectodermal structures

06.09.2013 | Erika Toledo Fonseca, Fernanda Menezes De Oliveira Silva, Dayane Alcântara, Rafael Carvalho Cardoso, André Luís Fran ..., Microscopy Research and Technique, 2013

ABSTRACT Birds occupy a prominent place in the Brazilian economy not only in the poultry industry but also as an animal model in many areas of scientific research. Thus the aim of this study was to provide a description of macro and microscopic aspects of the ectoderm‐derived structures in ...
