Advances in Research and Applications of Smart Hydrogels Part I: Preparation Methods and Classification

Atmospheric Pressure Chemical Ionization Sources Used in the Detection of Explosives by Ion Mobility Spectrometry

Explosives detection is a necessary and wide spread field of research. From large shipping containers to airline luggage, numerous items are tested for explosives every day. In the area of trace explosives detection, ion mobility spectrometry (IMS) is the technique employed most often because it is a quick, simple, and accurate way to test many items in a short amount of time. Detection by IMS ...

Nanoelectronic Chemical Sensors for Chemical Agent and Explosives Detection

A new class of nanometer-scale, low power, solidstate devices is being investigated for the detection of CW agents and other hazardous vapors. These nanoelectronic chemical vapor sensors, or “chemiresistors” are comprised of nanometer-sized gold particles (1.2-2.4nm) encapsulated by monomolecular layers of functionalized alkanethiols (R-SH) deposited as thin films on interdigitated microelectro...

Recent advances in mechanical methods of cardiopulmonary resuscitation.

Several new CPR techniques and devices have been developed and tested since the first report of manual closed-chested cardiopulmonary resuscitation (CPR) nearly four decades ago. These devices and techniques include vest CPR, interposed abdominal counterpulation CPR, active compression-decompression CPR, an impedance threshold valve, intra-aortic balloon pump and phased thoracic-abdominal count...

Advances in Animal Cognition

This editorial endorses a diverse approach to the study of animal cognition and emphasizes the theoretical and applied gains that can be made by embracing this approach. This diversity emerges from cross-talk among scientists trained in a variety of backgrounds and theoretical approaches, who study a variety of topics with a range of species. By shifting from an anthropocentric focus on humans ...
