The U.S. Department of Energy’s (DOE) Office of Science announced allocations of supercomputer access to 56 high-impact computational science projects for 2023 through its Innovative and Novel Computational Impact on Theory and Experiment (INCITE) program. These awards, which will pursue transformational advances in science and engineering, account for 60% of the available time on the leadership-class supercomputers at DOEs Argonne and Oak Ridge national laboratories.

The projects will support a broad range of large-scale research campaigns to advance knowledge in areas ranging from astrophysics to sustainable energy technologies to materials design and discovery.

Jointly managed by the Argonne Leadership Computing Facility (ALCF) and the Oak Ridge Leadership Computing Facility (OLCF), the INCITE program is the primary means by which the facilities fulfill their mission to advance open science by providing the scientific community with access to their powerful supercomputing resources. The ALCF and OLCF are DOE Office of Science user facilities.

As LHC Run 3 gets into its stride and the first results at a new energy frontier roll in (p5), all eyes are on what’s next: the High-Luminosity LHC (HL-LHC), scheduled to start operations in 2029. Civil engineering for the major upgrade is complete (p7) and new crystal collimators for HL-LHC operations are to be put to the test during the current run (p35). Looking beyond the LHC, how best to deal with the millions of cubic metres of excavation materials from a future circular collider? (p9), and a new project to explore the use of high-temperature superconductors for FCC-ee (p8). The HL-LHC and proposed future colliders also feature large in the recent US Snowmass community planning exercise (p23).

Organic electronic-based gas sensors hold great potential for portable healthcare-and environment-monitoring applications. It has recently been shown that introducing a porous structure into an organic semiconductor (OSC) film is an efficient way to improve the gas-sensing performance because it facilitates the interaction between the gaseous analyte and the active layer. Although several methods have been used to generate porous structures, the development of a robust approach that can facilely engineer the porous OSC film with a uniform pore pattern remains a challenge. Here, we demonstrate a robust approach to fabricate porous OSC films by using a femtosecond laser-processed porous dielectric layer template. With this laser-assisted strategy, various polymeric OSC layers with controllable pore size and well-defined pore patterns were achieved.

First insights into engineering crystal growth by atomically precise metal nanoclusters have been achieved in a study performed by researchers in Singapore, Saudi Arabia and Finland. The work was published in Nature Chemistry.

Ordinary solid matter consists of atoms organized in a crystal lattice. The chemical character of the atoms and lattice symmetry define the properties of the matter, for instance, whether it is a metal, a semiconductor or and electric insulator. The lattice symmetry may be changed by ambient conditions such as temperature or high pressure, which can induce structural transitions and transform even an electric insulator to an electric conductor, that is, a metal.

Larger identical entities such as nanoparticles or atomically precise metal nanoclusters can also organize into a crystal lattice, to form so called meta-materials. However, information on how to engineer the growth of such materials from their building blocks has been scarce since the crystal growth is a typical self-assembling process.

After several years of developing the theoretical ideas, University of Illinois Urbana-Champaign researchers have validated multiple novel predictions about the fundamental mechanism of transport of atoms and molecules (penetrants) in chemically complex molecular and polymer liquid matrices.

The study from Materials Science and Engineering (MatSE) Professor Ken Schweizer and Dr. Baicheng Mei, published recently in Proceedings of the National Academy of Sciences (PNAS), extended the theory and tested it against a large amount of experimental data. MatSE Associate Professor Chris Evans and graduate student Grant Sheridan collaborated on this research by providing additional experimental measurements.

“We developed an advanced, state-of-the art theory to predict how molecules move through complex media, especially in polymer liquids,” Schweizer said. “The theory abstracted what the important features are of the chemically complex molecules and of the polymeric medium that they’re moving through that control their rate of transport.”

Digital transformation has been positioned as a cure-all to many of the challenges today’s enterprises face. But to fully reap the benefits of a digital transformation, businesses need to do more than just adopt the latest tools and apps. They also have to change their attitudes, practices and processes around data and technology, throughout their own organization and in their interactions with partners and customers.

“Digital transformation requires a jump on the technology side, but it requires a leap on the people side,” says Bill Gundrey, executive director for digital engineering and operations at Raytheon Missiles & Defense. “At Raytheon, digital transformation is a team sport. It impacts every function in our company, as well as customers and suppliers. We had to change the way people think about data and technology.”

It took two electric trucks to cover a distance of 250 miles.

Remy Oktay, a US engineering student, has successfully completed a test run and is preparing to launch the world’s first electric flight that an electric vehicle will power.

Therefore the EV plane will need to be recharged three times.

Other proteins work as well meaning the process can be scaled without interfering with food supplies.

Researchers at Princeton Engineering have found that egg whites can be used to cheaply remove salt and microplastics from seawater, according to a press release by the institution published on Thursday.

The scientists used the food substance to create an aerogel, a lightweight and porous material that can be used in many types of applications, including water filtration, energy storage, and sound and thermal insulation.

Solar cells that are stretchable, flexible and wearable won the day and the best poster award from a pool of 215 at Research Expo 2016 April 14 at the University of California San Diego. The winning nanoengineering researchers aim to manufacture small, flexible devices that can power watches, LEDs and wearable sensors. The ultimate goal is to design and build much bigger flexible solar cells that could be used as power sources and shelter in natural disasters and other emergencies.

Research Expo is an annual showcase of top graduate research projects for the Jacobs School of Engineering at UC San Diego. During the poster session, graduate students are judged on the quality of their work and how well they articulate the significance of their research to society. Judges from industry, who often are alumni, pick the winners for each department. A group of faculty judges picks the overall winner from the six department winners.
