Fig. 1: Experimental data: (a) Two-dimensional (2D) scan of the sum of the electric fields E(?,t) of the three driving THz pulses A, B, and C as a function of the coherence time ? and the real time t. The contour plot is colored red for positive electric fields and blue for negative fields. (b) 2D scan of electric field ENL(?,t) nonlinearly emitted by the two-phonon coherence in InSb. The orange dashed line indicates the center of pulse A. (c) Electric field transient ENL(0,t) for the coherence time ?=0. Credit: Image courtesy of Forschungsverbund Berlin e.V. (FVB)

(Tech Xplore)—Over at the University of California Berkeley the field of biomimetics is alive and well with researchers actively studying and harnessing the way animals can move and manage their environments— little is ignored in the mechanics and dynamics as the researchers see if they can come up with little robots with like capabilities

Over at the Uni of CA Berkeley the field of biomimetics is alive and well with researchers actively studying and harnessing the way animals can move and manage their environments. A video is up as well that shows how “Two VelociRoACH Robots Cooperatively Climb a Step.” The importance of their work is focused on the fact that they used two robots to accomplish an otherwise daunting task of climbing something...

HoloFlex (2016): Holographic 3D Editor with Teapot

Researchers at the Human Media Lab at Queen’s University have developed the world’s first holographic flexible smartphone. The device, dubbed HoloFlex, is capable of rendering 3D images with motion parallax and stereoscopy to multiple simultaneous users without head tracking or glasses.”HoloFlex offers a completely new way of interacting with your smartphone. It allows for glasses-free interactions with 3D video and images in a way that does not encumber the user.” says Dr. Vertegaal.

HoloFlex features a 1920×1080 full high-definition Flexible Organic Light Emitting Diode (FOLED) touchscreen display. Images are rendered into 12-pixel wide circular blocks rendering the full view of the 3D object from a particular viewpoint...

Using a layer of molybdenum disulfide less than one nanometer thick, researchers in Rice University’s Thomann lab were able to design a system that absorbed more than 35 percent of incident light in the 400- to 700-nanometer wavelength range. Credit: Thomann Group/Rice University

Mechanics know molybdenum disulfide (MoS2) as a useful lubricant in aircraft and motorcycle engines and in the CV and universal joints of trucks and automobiles. Rice University researcher Isabell Thomann knows it as a remarkably light-absorbent substance that holds promise for the development of energy-efficient optoelectronic and photocatalytic devices.

“Basically, we want to understand how much light can be confined in an atomically thin semiconductor monolayer of MoS2,” said Assitant/Prof Thomann...
