Nordson YESTECH Ensures Trenton Systems' Quality
San Jose, CA — Brainstorming has never gone out of style, but it takes on a new urgency as the centerpiece of Comet’s new state-of-the-art labo- ratory in Silicon Valley. The Comet Group, which comprises Comet Plas-
ma Control Technologies (PCT), YXLON and ebeam, has opened Comet Lab One, a collaborative space for brainstorming, research and development. Customers, such as the many tech titan OEMs in the area, as well as hundreds of smaller contract manufacturers and start-
ups, will now have hands-on access to the Comet Group’s RF and plasma technology, X-ray and computed to- mography (CT) systems, and electron beam lab. The idea was formed in 2016 by
Paul Smith, senior VP at Comet Technologies USA and general man- ager of Lab One, who sought to find a way to consolidate the company’s branches and to leverage the technol- ogy of each. “Our new Lab One is a time-saver for local companies, be- cause it provides inspection services extremely close to their location,” says Smith. “It’s a place where, together, we turn jointly-developed ideas into

Troy/Ithaca, NY — Lithium elec- trodes coated with indium could be the basis for more powerful, longer- lasting, rechargeable batteries. The coating hinders undesirable side-re- actions between the electrode and electrolyte, provides a more uniform deposition of lithium when charging, and augments storage in the lithium anode through alloying reactions be- tween lithium and indium, as report- ed by American scientists in the jour- nal Angewandte Chemie. Their suc-
cess stems from the diffusion of lithi- um ions along the interfacial layer. Today’s lithium-ion batteries
usually have graphite anodes that store lithium when the batteries are charged. An interesting alternative is presented by batteries with metal- lic anodes, such as lithium metal, which promise significantly higher storage capacity. However, a signifi- cant hurdle barring their successful implementation has been the uneven deposition of the metal during the charging process, which leads to the formation of dendrites. After longer uses of the battery,
these dendrites can grow so exten- sive that they short-circuit the bat- tery. There are also undesirable side- reactions between the reactive metal electrodes and the electrolyte, which significantly reduce the lifetime of the batteries. The formation of a sta- ble, passivating layer that prevents

Air-Sensitive Semiconductors Under Study for Nanoelectronics
Tomsk, Russia — A research group of scientists from Tomsk Polytechnic University, Germany and Venezuela have proven the viability of a two-di- mensional semiconductor gallium se- lenide (GaSe) in air. This discovery will allow the manufacturing of su- perconducting nanoelectronics based on GaSe, which, reportedly, has not been achieved until now. The study was published in Semiconductor Sci- ence and Technology. One of the promising areas of
materials science is the study of two- dimensional (2D) materials, i.e. thin films consisting of one or several atomic layers. 2D materials, due to their electrical superconductivity and strength, could be a basis for to- day’s nanoelectronics. Optic applica- tions in nanoelectronics require ad- vanced materials capable of “gener- ating” great electron fluxes upon light irradiation. GaSe is one of the 2D semiconductors that can cope with this problem most efficiently. “Some research teams abroad
tried to create electronic devices based on GaSe. However, despite extensive theoretical studies of this material, which were published in major scien- tific journals, the stability of the mate- rial in real devices remained unclear,” says professor Raul Rodriguez, of Tomsk Polytechnic’s department of lasers and lighting engineering. The research team revealed the
