Compact clocks enable GPS with centimeter-scale accuracy

A research team led by Prof. Li Xingxing and academician Yang Jinlong from University of Science and Technology of China (USTC) has developed two-dimensional (2D) chiral metal-organic frameworks as Rashba-Dresselhaus (R-D) semiconductors with large spin splitting. The study was published in Chemical Science.

In a study led by Prof. Wei Xu (Interdisciplinary Materials Research Center, School of Materials Science and Engineering, Tongji University) and published in the journal National Science Review, a research team achieved the successful synthesis of a one-dimensional carbon chain on the Au(111) surface, with the longest chain containing approximately 120 carbon atoms, and the polyynic nature of the carbon chain was…

Scientists have created an n-channel transistor using diamond for the first time, potentially leading to faster components that can work in extreme conditions.

In diamonds (and other semiconducting materials), defects are a quantum sensor's best friend. That's because defects, essentially a jostled arrangement of atoms, sometimes contain electrons with an angular momentum, or spin, that can store and process information. This "spin degree of freedom" can be harnessed for a range of purposes, such as sensing magnetic fields or making a quantum network.

Refractory organic pollutants, including phenols, perfluorinated compounds, and antibiotics, are abundant in various industrial wastewater streams such as chemical, pharmaceutical, coking, and dyeing sectors, as well as municipal and domestic sources. These pollutants pose significant threats to ecological well-being and human health.

An ideal infrared (IR) nonlinear optical (NLO) crystal must have the advantages of a wide transmittance range, impressive laser-induced damage threshold (LIDT), sufficient birefringence index, bulk single-crystal form, and physicochemical stability.

Researchers have created chip-based photonic resonators that operate in the ultraviolet (UV) and visible regions of the spectrum and exhibit a record low UV light loss. The new resonators lay the groundwork for increasing the size, complexity and fidelity of UV photonic integrated circuit (PIC) design, which could enable new miniature chip-based devices for applications such as spectroscopic sensing, underwater…

Blue light is vital for light-emitting devices, lighting applications, as well as smartphone screens and large screen displays. However, it is challenging to develop efficient blue organic light-emitting diodes (OLEDs), owing to the high applied voltage required for their function. Conventional blue OLEDs typically require around 4 V for a luminance of 100 cd/m2. This is higher than the industrial target of 3.7…

According to recent studies, incorporating a perovskite layer on top of a silicon base could significantly enhance the efficiency of energy absorption in solar panels. However, the...

Envision a realm where light can be meticulously controlled and manipulated at minuscule scales, unlocking unprecedented potentials for nanotechnology and quantum information technology. Recent breakthroughs in quantum research have propelled us closer to a reality that may be more achievable than previously realized.

A facile technique for reproducibly creating Swiss-cheese-like nanomaterials has been developed by researchers at KAUST. This material, and the method required to create it, could help in the development of further advanced materials with applications in photocatalysis and optoelectronics.

Planar to FinFET to Nanosheet to Complementary FET to 2D

Metal oxides are a promising catalyst for photoelectrochemical (PEC) water splitting to produce hydrogen as alternative energy. However, their effectiveness is restricted at low voltage. A research team led by scholars from City University of Hong Kong (CityU), Australia and Germany successfully mediated the poor charge carrier transport at low voltage by adding phosphorus to a metal oxide catalyst, which reduced…

New TRIUMF research from the Saint Mary's University-led IRIS group has unveiled an unexpected shape deformation in the nucleus of helium-8 (He8), providing further insight into the unique dynamics of how neutron-rich nuclei take shape and maintain stability.

Thermal scientists from the Iowa State University, Shenzhen University, and Shanghai University of Engineering Science, have developed a new thermal probing technique based on the ratio of two resonance Raman scattering peak intensities.

Power and RF will drive volume, but many other possible uses for GaN are under consideration.
