Advances in vacuum-tight in situ liquid cell TEM systems have attracted significant attention because of the ability to directly interpret chemical and electrochemical reactions within their native liquid environments [1]. Conducting quantitative in situ electrochemistry experiments within the S/TEM is feasible using the relatively new platform of in situ electrochemical S/TEM (ec-S/TEM). In th...

Performance evaluation of implantable devices is not new to medical device manufacturers, specifically implant manufacturers. A focus on corrosion resistance of implant devices has prompted members of the medical device industry, along with the United States Food and Drug Administration [USFDA] to set forth a guide for performance testing. Although actual corrosion resistance of a material can ...

This paper describes an inexpensive, handheld device that couples the most common forms of electrochemical analysis directly to "the cloud" using any mobile phone, for use in resource-limited settings. The device is designed to operate with a wide range of electrode formats, performs on-board mixing of samples by vibration, and transmits data over voice using audio--an approach that guarantees ...

Desorption electrospray ionization mass spectrometry (DESI-MS) previously has been used to capture and identify transient intermediates in electrochemical redox reactions on a platinum-covered rotating waterwheel. We present here two different setups that use a flat surface with porous carbon tape as the working electrode, where analyte-containing microdroplets from the DESI probe contacted wit...

In this present study, we fabricated an LSI-based amperometric chip device with highly temporal and spacial resolution for electrochemical imaging, applied to detection of alkaline phosphatase (ALP) activity and respiration activity of embryonic stem (ES) cells.

We report the synthesis of a soluble perylene-based small molecule for use as an n-type emissive material for organic optoelectronic device applications, and demonstrate the material in a light-emitting electrochemical cell configuration.

A two-layer light-emitting electrochemical cell device based on a new perylenediimide-iridium-complex dyad is presented emitting in the deep-red region with high external quantum efficiencies (3.27%).

The ability to obtain sequence-specific genetic information about rare target organisms directly from complex biological samples at the point-of-care would transform many areas of biotechnology. Microfluidics technology offers compelling tools for integrating multiple biochemical processes in a single device, but despite significant progress, only limited examples have shown specific, genetic a...
