A new study on thin films of glass shows how they can be fabricated to be denser and more stable, providing a framework for new applications and devices through better design.

A group of scientists has introduced a new GAN that can turn your sketches into realistic pictures.

Physicists of the Technische Universität Dresden introduce the first implementation of a complementary vertical organic transistor technology, which is able to operate at low voltage, with adjustable inverter properties, and a fall and rise time demonstrated in inverter and ring-oscillator circuits of less than 10 nanoseconds, respectively. With this new technology they are just a stone’s throw away from the commercialization of efficient, flexible and printable electronics of the future. Their groundbreaking findings are published in the renowned journal Nature Electronics.

Poor performance is still impeding the commercialization of flexible and printable electronics. Hence, the development of low-voltage, high-gain, and high-frequency complementary circuits is seen as one of the most important targets of research. High-frequency logic circuits, such as inverter circuits and oscillators with low power consumption and fast response time, are the essential building blocks for large-area, low power-consumption, flexible and printable electronics of the future. The research group “Organic Devices and Systems” (ODS) at the Institute of Applied Physics (IAP) at TU Dresden headed by Dr. Hans Kleemann is working on the development of novel organic materials and devices for high performance, flexible and possibly even biocompatible electronics and optoelectronics. Increasing the performance of organic circuits is one of the key challenges in their research. It was only some month ago, when Ph.D.

Current tissue engineering strategies lack materials that promote angiogenesis. Here the authors develop a microfluidic in vitro model in which chemokine-guided endothelial cell sprouting into a tunable hydrogel is followed by the formation of perfusable lumens to determine the material properties that regulate angiogenesis.

The Air Force Research Laboratory at Kirtland Air Force Base has released a new analysis of the Department of Defense’s investments into directed energy technologies, or DE. The report, titled “Directed Energy Futures 2060,” makes predictions about what the state of DE weapons and applications will be 40 years from now and offers a range of scenarios in which the United States might find itself either leading the field in DE or lagging behind peer-state adversaries. In examining the current state of the art of this relatively new class of weapons, the authors claim that the world has reached a “tipping point” in which directed energy is now critical to successful military operations.

One of the document’s most eyebrow-raising predictions is that a “force field” could be created by “a sufficiently large fleet or constellation of high-altitude DEW systems” that could provide a “missile defense umbrella, as part of a layered defense system, if such concepts prove affordable and necessary.” The report cites several existing examples of what it calls “force fields,” including the Active Denial System, or “pain ray,” as well as non-kinetic counter-drone systems, and potentially counter-missile systems, that use high-power microwaves to disable or destroy their targets. Most intriguingly, the press release claims that “the concept of a DE weapon creating a localized force field may be just on the horizon.”

The Air Force wants Hermeus Corporation to prove the concept for a high-speed transport, and maybe more.

The U.S. Air Force is looking to field a new type of low-cost yet advanced drone to be used as an “Off-Board Sensing Station,” or OBSS. Details remain very limited, and the few publicly available Air Force Research Laboratory documents on the program state that specifics are only available to approved contractors. Still, according to Kratos, one of the companies involved with the effort, the new unmanned platform could potentially end up being as revolutionary as the firm’s stealthy XQ-58 Valkyrie has been.

The remarks about the OBSS program were made by Eric DeMarco, President and Chief Executive Officer of Kratos Defense & Security Solutions, during a company earnings call this week. DeMarco says that if the program is successful, the company believes it “could ultimately be as significant and transformational to Kratos as we expect Valkyrie to be.” The CEO added that the OBSS program is a signal that “the total addressable market opportunity for Kratos’ class of tactical drones is rapidly expanding and clarifying, as the Department of Defense strives for affordable force multiplier systems and technologies.”
