The Hong Kong Institute for Advanced Study (HKIAS) is pleased to announce the appointment of Professor Zhongfan Liu as a Senior Fellow, starting from September 2024.
A team led by scientists at ORNL identified and demonstrated a method to process a plant-based material called nanocellulose that reduced energy needs by a whopping 21%, using simulations on the lab’s supercomputers and follow-on analysis.
The complicated chemistry of legacy nuclear waste presents a challenge in environmental management. The presence of radioactive ions induces chemical changes that range from faster than the blink of an eye to decades in the making. Since 2016, researchers led by Pacific Northwest National Laboratory (PNNL) have been persistent in tracking and analyzing the chemical phenomena that occur in the extreme environments found in legacy nuclear waste.
Experiment findings will help nuclear industry model, design and construct clean nuclear energy systems, and continue an impressive safety legacy.
Revealing the underlying patterns behind complex systems and predicting their behavior has become a focal point of current interdisciplinary research. In this study, researchers delved into the intrinsic mechanisms of complex systems behavior of photonic phase transitions in one-dimensional Rayleigh scattering systems by establishing a Rayleigh-scattering-phase-variation model with experimental realization. This work expands the current understanding of photonic phase transitions, which is an important reference value for the study of various complex systems. Furthermore, it advances the application of random fiber lasers in critical fields such as high-power laser devices.
The introduction of micropatterns is an effective strategy in enhancing the sensitivity of capacitive pressure sensors. Towards this goal, scientist in China developed a novel approach for fabricating random conical array (RCA) microstructures based on laser speckle grayscale lithography.
In a machine learning paper recently published in the journal npj Computational Materials, a team of researchers from Sandia National Laboratories and Brown University have introduced a universal way to accelerate virtually any kind of simulation.

Scientists have developed a new way to create miniature optical components that shape light into non-diffracting beams, paving the way for smaller, more versatile optical systems. By directly writing tiny patterns with a femtosecond laser, they can tailor these components to specific tasks, like trapping particles or manipulating light for advanced imaging.
Advances in information technology demand complex micro-optical elements with nanoscale precision. Femtosecond laser direct writing (FsLDW) rises to the challenge, using ultrashort pulses to create three-dimensional micro-nano structures. This versatile technique boasts diverse material compatibility and can fabricate imaging and non-imaging micro-optical elements, opening doors for next-generation stereoscopic systems.
When light shines on a semiconductor, it excites the electrons, leaving behind a “hole.” Electrons and these holes attract each other to form excitons, which can interact with other unpaired charges to alter the shape, direction, and/or frequency of a beam of light in the semiconductor. Researchers demonstrated that this response is unprecedently strong in a two-dimensional device made of three atomic layers of the semiconductor tungsten di-selenide.
Researchers at the University of Illinois Urbana-Champaign have trained neural networks to predict interactions between irregularly shaped particles to accelerate molecular dynamics simulations.
Ensuring that scientific funding goes to states and territories that have typically received smaller fractions of federal research dollars in the past, the Department of Energy (DOE) today announced $36 million in funding for 39 research projects in 19 states via the Established Program to Stimulate Competitive Research (EPSCoR). The grants connect innovative ideas from scientists at eligible institutions with leading-edge capabilities at the DOE national laboratories.
Argonne and the University of Münster agreed to collaborate on advanced battery materials, building on past lithium battery research. This collaboration aims to enhance battery knowledge and address challenges in energy density, cost and lifespan.
