Wafer level packaging could reduce the cost of MEMS based sensors through simplified processing and inexpensive components. A novel vacuum tight seal referred to as the wedge seal method is proposed in this paper. The seal consists of a silicon wedge forced into a pliable material (typically a metal) that is attached to the component wafer. The wedge-seal addresses some of the requirements of m...

The presence of mastitis in bred dairy heifers can adversely affect the development of milkproducing tissues, leading to less than maximal milk production and increased somatic cell counts (SCC) during their first lactation. Use of nonlactating cow therapy has been beneficial in curing existing intramammary infections (IMI), and teat sealants have been beneficial in preventing new IMI from deve...

We describe highly efficient and stable bifacial perovskite solar cells incorporating carbon nanotube network films as a back contact enabling perovskite/CIS 4-terminal tandem to reach apower conversion efficiency of over 27%.

In article number 2001480 by Jongho Lee and co-workers, a unique approach is developed for the design integration of sustainably powered, bi-facial multi-functional electronic implant that provides several milliwatts power under skin feedback functions stand-alone sensing, processing, stimulation in flexible forms while occupying half area required single-faced ones.

Basic methods for the determination of internal electrical field in a-Si:H solar cells, derived from the standard Time of Flight (TOF) technique, are presented. One of these methods, based on charge collection, is very attractive; is is particularly simple, does not need high time resolution and is insensitive to the transport dispersion. It allows characterisation of the internal electrical ov...

BACKGROUND Polar bears (Ursus maritimus) of the Beaufort Sea enter hyperphagia in spring and gain fat reserves to survive periods of low prey availability. We collected information on seals killed by polar bears (n=650) and hunting attempts on ringed seal (Pusa hispida) lairs (n=1396) observed from a helicopter during polar bear mark-recapture studies in the eastern Beaufort Sea in spring in 19...

While high-throughput planar patch-clamp instruments are now established to perform whole-cell recordings for drug screening, the conventional micropipette-based approach remains the gold standard for performing cell-attached single-channel recordings. Generally, planar platforms are not well-suited for such studies due to excess noise resulting from low seal resistances and the use of substrat...
