Published Revolutionary breakthrough in solar energy: Most efficient QD solar cells



A research team has unveiled a novel ligand exchange technique that enables the synthesis of organic cation-based perovskite quantum dots (PQDs), ensuring exceptional stability while suppressing internal defects in the photoactive layer of solar cells.
Published Angle-dependent holograms made possible by metasurfaces



Scientists unveil metasurface technology, allowing for angle-dependent holograms.
Published Engineering a coating for disease-free produce



Texas A&M researchers combine food-grade wax with essential oils to defend produce from bacteria.
Published Plastic recycling with a protein anchor



Polystyrene is a widespread plastic that is essentially not recyclable when mixed with other materials and is not biodegradable. A research team has now introduced a biohybrid catalyst that oxidizes polystyrene microparticles to facilitate their subsequent degradation. The catalyst consists of a specially constructed 'anchor peptide' that adheres to polystyrene surfaces and a cobalt complex that oxidizes polystyrene.
Published Wildfires linked to surge in mental health-related emergency department visits



A new studyshows wildfires lead to an increase of anxiety-related emergency department visits in the western United States, amplifying the concerning parallel trajectory of two escalating public health crises -- mental health and climate change.
Published New chip opens door to AI computing at light speed



Engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.
Published First human trial shows 'wonder' material can be developed safely



A revolutionary nanomaterial with huge potential to tackle multiple global challenges could be developed further without acute risk to human health, research suggests.
Published Microscopy: Overcoming the traditional resolution limit for the fast co-tracking of molecules



Researchers have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale.
Published Nanoparticles that can light up the lymph node cancer cells otherwise undetectable by MRI



Researchers have developed a new nanoparticle that can 'hitch a ride' on immune cells, or monocytes. Because of its tiny size, the particle can tag along directly into lymph nodes and help metastasis show up on MRIs where it would otherwise be too hard to detect. The process offers game-changing benefits for the early detection of cancer metastasis in the lymph nodes. While previously, metastasis could only be assessed by an increase in lymph node size; the new particles could lead to MRI contrast agents that can highlight metastatic cells in lymph nodes that may otherwise appear normal.
Published A century of reforestation helped keep the eastern US cool



Widespread 20th-century reforestation in the eastern United States helped counter rising temperatures due to climate change, according to new research. The authors highlight the potential of forests as regional climate adaptation tools, which are needed along with a decrease in carbon emissions.
Published Exploring the effect of ring closing on fluorescence of supramolecular polymers



The properties of supramolecular polymers are dictated by the self-assembled state of the molecules. However, not much is known about the impact of morphologies on the properties of nano- and mesoscopic-scale polymeric assemblies. Recently, a research team demonstrated how terminus-free toroids and random coils derived from the same luminescent molecule show different photophysical properties. The team also presented a novel method for purifying the toroidal structure.
Published Scientists study the behaviors of chiral skyrmions in chiral flower-like obstacles



Chiral skyrmions are a special type of spin textures in magnetic materials with asymmetric exchange interactions. They can be treated as quasi-particles and carry integer topological charges. Scientists have recently studied the random walk-behaviors of chiral skyrmions by simulating their dynamics within a ferromagnetic layer surrounded by chiral flower-like obstacles. The simulations reveal that the system behaves like a topological sorting device, indicating its use in information processing and computing devices.
Published Can hydrogels help mend a broken heart?



You can mend a broken heart this valentine s day now that researchers invented a new hydrogel that can be used to heal damaged heart tissue and improve cancer treatments.
Published EVs that go 1,000 km on a single charge: Gel makes it possible



Engineers apply electron beam technology to develop an integrated silicon-gel electrolyte system.
Published New approach for fast and cost-effective pathogen detection



The ability to detect diseases at an early stage or even predict their onset would be of tremendous benefit to doctors and patients alike. A research team now develops intelligent, miniaturized biosensor devices and systems using nanomaterials to determine biomolecules and cells as well as biochemical reactions or processes as disease markers. The team's current publication describes the development of a portable, palm-sized test system that can simultaneously carry out up to thirty-two analyses of one sample.
Published Researchers reveal elusive bottleneck holding back global effort to convert carbon dioxide waste into usable products



Think of it as recycling on the nanoscale: a tantalizing electrochemical process that can harvest carbon before it becomes air pollution and restructure it into the components of everyday products. The drive to capture airborne carbon dioxide from industrial waste and make it into fuel and plastics is gaining momentum after a team of researchers uncovered precisely how the process works and where it bogs down.
Published Structural isomerization of individual molecules using a scanning tunneling microscope probe



An international research team has succeeded in controlling the chirality of individual molecules through structural isomerization. The team also succeeded in synthesizing highly reactive diradicals with two unpaired electrons. These achievements were made using a scanning tunneling microscope probe at low temperatures.
Published New study points to more climate extremes



A new study has found similarities between long-term climatic changes in South Australia and temperate agricultural areas in Argentina -- highlighting similarities across these Southern Hemisphere countries. As temperature records tumble, and the threat of bushfires and dry conditions looms large, researchers renew the urgency of calls to make more concerted efforts to prepare for climate extremes in South Australia.
Published Unveiling the generation principles of charged particles 'trion' in 2D semiconductor



Researchers pioneer dynamic manipulation and the generation principles of trion at the nanoscale using tip-enhanced cavity-spectroscopy.
Published Ultra-sensitive lead detector could significantly improve water quality monitoring



Engineers have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to the femtomolar range, which is one million times more sensitive than previous technologies.
