High-spatial-resolution Interferometry Enters Multi-Wavelength Era 2021-09-20
Interferometers are widely used in various high spatial resolution imaging techniques to extend the diffraction limit. However, the conventional interferometric methods only work when the photons have the same wavelength.In a study publishe...
Researchers Realize Measurement Beyond Standard Quantum Limit with Nitrogen-vacancy Centers in Diamond 2021-08-30
Measurement is an important means of human cognition of nature and many measurements are limited by standard quantum limit (SQL). SQL is defined as the measured noise levels set by quantum mechanics. Quantum entanglement can be used to beat...
Researchers Develop Carbon Spring with High Compressibility and Stretchability 2021-08-27
Mechanical flexibility is a key factor determining the stability and durability of porous carbon materials. The compressive brittleness of porous carbon materials has been well resolved. However, reversible stretchability property remains a...
Researchers Quantify Critical Particle Distance 2021-08-25
Supported metal nanoparticles are of great importance in many industrial catalytic processes. Under high temperature, metal nanoparticle catalysts have a strong sintering tendency because of the sharply increased surface energy with the dec...
Researchers Reveal Phase-changing in Graphite by Interface Charge Injection 2021-08-16
Graphite, as an important material for Li battery anode and graphene preparation, can exist in two phases: the Bernal (2H) phase and the rhombohedral (3R) phase. The 2H phase has relatively low energy and high proportion in graphite powder,...
Effective Temperatures Connect Equilibrium and Nonequilibrium Systems 2021-08-15
What is temperature? A direct understanding of temperature is the specific number shown in thermometers. A much more scientific definition of temperature is a statistical concept in equilibrium systems. However, what about nonequilibrium sy...
Researchers Realize Non-line-of-sight Imaging with Picosecond Temporal Resolution 2021-08-14
Usually, the traditional optical imaging strategies can only image the target objects within the field of camera. However, through the non-line-of-sight (NLOS) which can record the time-of-flight information about single-photon, the target ...
3D Ordered Channel Enhances Electrocatalysis 2021-08-13
A team led by Prof. YU Shuhong and Prof. HOU Zhonghuai from the University of Science and Technology of China (USTC) developed a theory-guided microchemical engineering (MCE) approach to manipulate the reaction kinetics and thus optimize th...
Optical Fibers Successfully Detect Earthquakes 2021-08-10
When it comes to optical fibers, the underground optical cables that transmit tons of information at a time are more familiar to us. Few would ever associate optical fibers with earthquake detection.Recently, researchers from the University...
