How NASA prepare their astronauts by using vacuum chambers

How NASA prepare their astronauts by using vacuum chambers

Vacuum chambers are used by NASA as part of their vigorous pre-flight testing as they can replicate the extreme temperatures, lack of atmosphere, and lighting conditions that occur in space allowing them to prepare better for when they are really out there.


Innovations in polarimetry make thin-film semiconductors more feasible
All About Circuits

Researchers from Ludwig-Maximilians-Universitat (LMU), Rice University, and Los Alamos National Laboratory have developed a new polarimetry method to discover properties of thin-film semiconductors made of transition metal dichalcogenides.

Researcher using kinetics, not temperature, to make ceramic coatings
Science Daily

A new study lays down ceramic coatings kinetically at room temperature. Coating at room temperature makes microelectronics design and fabrication more flexible and could someday lead to better, less expensive microelectronics components that underpin modern technology.

US solar growth blows away previous records

The U.S. solar market nearly doubled its electricity-generating capacity last year, as 14.6 gigawatts (GW) of new photovoltaic capacity was installed throughout the country. There was a 95% increase in new solar installations over the previous year, when 7.4GW were installed, according to a new report from GTM Research and the Solar Energy Industries Association (SEIA).


A new angle on antireflection coatings
Optics & Photonics

Antireflection (AR) coatings have a long history in optics, in applications ranging from lenses to advanced imaging systems. But for plastic optics in certain applications, such as exterior solar concentrators, coming up with an AR coating tough enough to stand up to the challenges of harsh environments has proved a tricky proposition.

Optically active thin films: Switchable thin films II
Vacuum Technology & Coating

This is the second column addressing switchable optical properties in thin films. Electrochromic (EC) devices were discussed last month. This month we address other switching mechanisms such as heat (thermochromic) and light (photochromic). The ideal window would be one with optical properties that could readily adapt in response to changing cli-climatic...
