Putting individuals back in contact
2011Researchers have commented that linguistic complexity and the level of social integration can constrain adults’ ability to acquire phonological changes (Chambers 1992; Kerswill 1996; Evans 2004). This preliminary study explores the extent to which first generation Barbadian immigrants acquire Ipswich English (IpsE) or retain their own phonology (Island

Back-Side Contact Gear Mesh Stiffness
Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011Back-side gear tooth contact happens when the anti-backlash (or scissor) gears are applied or tooth wedging occurs. An accurate description of the back-side gear tooth mesh stiffness is important to any study on gear dynamics that involves tooth wedging or anti-backlash mechanism.

Interdigitated back contact silicon solar cells with laser fired contacts
2013 IEEE 39th Photovoltaic Specialists Conference (PVSC), 2013We report on interdigitated back-contact silicon solar cells with efficiencies above 18%, fabricated using laser fired silver for both base and emitter contacts. While laser fired aluminum contacts have been reported in the past, this is the first report to our knowledge describing a single-step laser process to dope the underlying silicon and create a

Back Point Contact Cells Modelling
1987A model of the Back Point Contact (BPC) cell behaviour has been developped and its results are presented here. The model is based on variable injection equations and therefore can be applied to cells of high or low base resistivity at any level of concentration. Also the series resistance mechanisms are analysed. The model explains most of the BPC cell

Shading effects in back-junction back-contacted silicon solar cells
2008 33rd IEEE Photovoltaic Specialists Conference, 2008One of the most often mentioned advantages of back-junction back-contacted silicon solar cells is that this cell structure has no shading losses, because metallization fingers and busbars are both located on the rear side of the solar cell. However, this is only true if only optical shading losses are regarded.

Back-contact back-junction silicon solar cells under UV illumination
Solar Energy Materials and Solar Cells, 2010Abstract The performance of n-type Si back-contact back-junction (BC-BJ) solar cells under illumination with high energy ultraviolet (UV) photons was investigated. The impact of the phosphorus doped front surface field (FSF) layer on the stability of the front surface passivation under UV illumination was investigated.

Back contact dye-sensitized solar cells
2017Abstract The objective of this work was to develop back-contact dye-sensitized solar cells (back-contact DSCs). These solar cells comprise working and counter electrodes on the same side of the dye-sensitized TiO2 film, in either an interdigitated or a coplanar configuration.

Gelest backs novel contact lens firm
C&EN Global Enterprise, 2019The specialty chemical maker Gelest has invested an undisclosed sum in OcuMedic, a New Jersey–based firm developing a drug-eluting soft contact lens that can replace eye drops. As part of the deal, Gelest will be OcuMedic’s exclusive supplier of acrylic monomers and reactive siloxanes used to produce the lenses.
