The first 1PW laser was commissioned in the USA in the late 1990s with many systems globally coming on-line throughout the 2000s opening up new and exciting areas of science. In the following years many laboratories strived to increase the power, and hence the focussed intensity, to the 10PW regime, to realise new theoretical thresholds of fundamental science. Several lasers throughout the world, are in the process of construction/commissioning to achieve this goal in China, Romania, Czech Republic, and France with others planned in Japan, USA, Russia and the UK. The first of these systems, ELI-NP in Romania, has recently been the first to demonstrate this landmark achievement.

More than 99% of air molecules on Earth exist below 50km altitude and therefore, there is certainly an upper limit on altitude for an aircraft to reach, while there is a lower limit on an orbit for a spacecraft to operate, as even a low density of air causes large drag due to the high orbit velocity with an unfavourable effect on its operation duration.
The tactical systems and operational environment of modern fighter aircraft are becoming increasingly complex.
Professor Huichan Zhao, Tsinghua University answers our questions about their work and Cambridge University Press’s new journal Wearable Technologies
The first edition of The Aeronautical Journal predates the first human powered flight by the Wright brothers by some five years. Even back then it knew that there was to be a rich future for man in flight to come.
Much effort is currently being devoted to reducing the environmental effect of commercial jet aircraft, but this is not simply a case of replacing kerosine with synthetic fuels, batteries or hydrogen propulsion. A great deal of research needs to be focused on new air vehicle designs that will lead to emissions-free (not just C02) flight.
Beyond the dark clouds there is light. Is this a topical description for the past, present and future of our industry? In the past, it was our ambition to travel fast and above the weather that inspired the development of the jet engine by its inventors, Sir Frank Whittle and Dr Hans von Ohain in the late 1930s and early 1940s.

Ultrashort and broadband laser sources are formidable tools for a wide range of scientific areas. In the field of ultrafast science, laser pulses lasting only a few optical cycles are used to generate secondary sources employed in probing matter at atomic scales. Such sources are also widely adopted in applications in ultrafast spectroscopy, pump-probe in chemistry, and optical coherence tomography among many other fields.

The experiments that students first encounter at college or university can be real passion-killers, consisting of time-worn experiments, supplied with detailed and prescriptive instructions leading to predictable and uninspiring outcomes. When students become truly active in their pursuit of learning they become immersed in processes and practices core to science and engineering.
I was obviously intrigued to be part of this team [of authors], as there was no question in my mind that Ali [Niknejad] and Gernot [Hueber] will be doing a great job in terms of organizing an effort to create the first book on millimeter-wave circuits for 5G applications
Due to the range of size, density, and resolution demands associated with industrial X-ray radiography, there is not a source that is “one-size fits all”... Altering the source characteristics to deliver what is needed requires continued study. This publication explores the X-ray emission from spatially constrained targets compared to standard foil targets. The research results are published in High Power Laser Science and Engineering, Volume 7, No. 2, 2019 (Armstrong, C. D. , et al. Bremsstrahlung emission from high power laser interactions with constrained targets for industrial radiography.)
“The faculty and staff at the Berkeley Wireless Research Center (BWRC) have a great tradition of meeting at a remote location to discuss new research directions for our center. It was during one of these meetings in Sausalito, CA (December 2013) that the vision for “xG” was born; see the figure below. To explain the origin of this figure, as a wireless research center, we are always looking at the world of wireless communication and trying to guess (and hopefully set) the research agenda in the right direction. We were compelled by a vision that involved the use of very high frequencies (mm-wave frequencies) to allow hundreds if not thousands of antennas to be integrated into small basestations (or access points) that formed a directional wireless mesh network, obviating the need for a fiber backhaul.”
An artificial intelligence system developed by a Cornell-led team has identified a promising material for creating more efficient fuel cells – a potential breakthrough in both materials science and machine learning.

Unless you’ve been hiding out in a cave in the mountains without any connectivity, you’ve heard the buzz and hype about 5G. 5G is supposed to solve every problem out there and to make our phones and tablets (and cars and computers, too) even more magical. People talk about 10X or 100X faster connections, more bandwidth and spectral efficiency, millisecond latency, enabling new applications like autonomous driving, AR/VR games, and even control over wireless. What’s real and what’s hype?

Without a doubt, the field of microelectronics has transformed our lives. Computers, smartphones, the devices and servers forming the backbone of the internet, computer chips in automobiles, airplanes, and appliances—all of these have changed the way we live today—and they all rely on microelectronics developments over the past several decades.
The Materials Research Society is making strides toward helping postdoctoral researchers through a number of awards and opportunities offered solely to scholars as this early stage of their career. One of these initiatives is the prestigious MRS Bulletin Postdoctoral Publication Prize, now in its third year.
There has been a notable trend in storytelling toward the redemption of beings that were once considered purely evil. In fantasy, for example, dragons have evolved from simple, violent animals into noble beasts, often of near- or above-human intellect, who act as helpers of humanity or as heroes in their own right. In science fiction, we’ve seen a similar shift in the purpose and personality of robotic characters. In her article in the April 2019 issue of MRS Bulletin, Hortense Le Ferrand, recipient of the 2018 MRS Bulletin Postdoctoral Publication Prize, connects the emergence of benevolent robots to “the use of soft materials, characterized by conformability, colors, and constant adaptation to the environment.”
Could a large-enough battery cushion the swings in wind and solar power? And can renewable energy be trusted, or are we just seeing technical challenges to implementation? In a recent review article published in MRS Energy & Sustainability, energy experts weigh in on these questions and consider the challenges and opportunities for technology and policy in relation to large-scale battery storage. The article also addresses a fascinating case study from South Australia, which currently houses the world's biggest battery.
As the Federal Energy Regulatory Commission (FERC) released an update to last year’s order on energy storage, MRS Energy & Sustainability publishes a timely collection of papers that unpack the issue of energy storage in the Midwest and beyond. Last February, FERC unanimously approved a landmark order in the fast-developing field of energy storage. FERC Order 841 directed grid operators across the US to develop market rules for energy storage to participate in the wholesale energy, capacity and ancillary services markets by treating storage as a generation resource.
