Photoacoustic tomography (PAT) is a novel hybrid medical imaging technique that enables precise imaging of biological tissue structures at different spatial scales. It has been widely used in various fields, including brain imaging, cancer detection, and cardiovascular disease diagnosis. However, due to limitations in data acquisition conditions, photoacoustic tomography systems typically can only...
Recently, Zhang Weijun, a research team of the Anguang Institute of the Chinese Academy of Sciences, Hefei Academy of Materials, made new progress in atmospheric formaldehyde detection, and the related achievements were published on the international TOP journal Sensors and Actors: B. Chemical under the title of "Portable highly sensitive laser absorption spectrum formaldehyde sensor based on comp...
Los Alamos National Laboratory (LANL) has developed a method for a quantum light emitter that stacks two different atomically thin materials together to achieve a light source that produces a stream of circularly polarized single photons. These light sources can in turn be used for a variety of quantum information and communication applications.According to Los Alamos researcher Han Htoon, the wor...
Terahertz waves have significant application value in communication and imaging. The nonlinear interaction between strong field ultrafast laser and matter is one of the important ways to generate terahertz waves. The experimental and theoretical research related to terahertz generation media such as plasma, gas, and crystal is relatively sufficient. However, liquid water is a strong absorbing medi...
Recently, DIT, a well-known semiconductor and display equipment manufacturer in South Korea, announced that the company has signed an agreement worth 20.52 billion Korean won to supply wafer processing equipment to SK Hynix. After the announcement, DIT's stock price rose for five consecutive days, entering the 16000 Korean won range. Then on the 22nd, it rose 2580 Korean won from the previous day'...
