Strain-free epitaxy of germanium film on mica

Fri, 17 Nov 2017 00:00:00 EST

(American Institute of Physics) Germanium was the material of choice in the early history of electronic devices, and due to its high charge carrier mobility, it's making a comeback. It's generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To address this aspect, researchers demonstrate an epitaxy method that incorporates van der Waals' forces to grow germanium on mica. They discuss their work in the Journal of Applied Physics.

No more deer in the headlight: Study finds large mammals do use road crossing structures

Fri, 17 Nov 2017 00:00:00 EST

(Frontiers) A pilot study finds that large mammals are more likely to use wildlife crossing structures than move past a random location in the surrounding habitat. Animal movement also varied between crossing structures in different locations, suggesting that location might be more important than design. These findings are a first step towards a better understanding of the effectiveness of wildlife crossing structures.

Evaluation of novel hybrid membranes for carbon capture

Fri, 17 Nov 2017 00:00:00 EST

(Tokyo University of Agriculture and Technology) Hybrid materials known as mixed matrix membranes are considered a promising approach to capture carbon dioxide and mitigate against global warming. These materials are derived from a polymer combined with porous nanoparticles. We show that materials prepared using porous organic polymers are resilient to the acidic impurities present in industrial gas streams, whereas other hybrid materials fail. This means that they can be effective in carbon capture applications where these impurities are present.

Noninvasive brain imaging shows readiness of trainees to perform operations

Thu, 16 Nov 2017 00:00:00 EST

(Rensselaer Polytechnic Institute) While simulation platforms have been used to train surgeons before they enter an actual operating room (OR), few studies have evaluated how well trainees transfer those skills from the simulator to the OR. Now, a study led by Rensselaer Polytechnic Institute that used noninvasive brain imaging to evaluate brain activity has found that simulator-trained medical students successfully transferred those skills to operating on cadavers and were faster than peers who had no simulator training.
