Mating sterile male mosquitoes with wild female mosquitoes can prevent mosquito eggs from hatching or larvae from developing, which can control mosquito populations. The technique of insect sterility was developed by two entomologists in the 1950s. Firstly, pest larvae were treated with radioactive radiation to select sterile male insects. Then, a large number of treated male insects were released and mated with wild female insects, preventing them from producing offspring normally and achieving the goal of controlling pest populations. Researchers successfully eliminated the green headed flies on the island by releasing male flies that were sterilized by irradiation. Another field release experiment was conducted on a 460 square kilometer island, achieving fly purification in just 7 weeks. Afterwards, this technology was widely adopted in many countries and regions around the world, successfully eliminating green headed flies.

Scientists led by NTU Singapore have developed and simulated a new energy-saving method that can produce highly focused and finely controlled X-rays that are a thousand times stronger than conventional methods.

X-ray detector is a device used to detect X-rays, which has a wide range of applications in medicine, science and industry. X-ray detectors convert X-rays into electrical signals for digital processing and imaging.

Researchers have developed an X-ray imaging technique that produces detailed images of organisms at much lower X-ray doses than previously possible.

X-ray technology plays a vital role in medical and scientific research, and recent advances in X-ray technology are enabling brighter, stronger beams and imaging of increasingly complex systems under real-world conditions.

X-ray generator is composed of X-ray tube, high voltage generator, tube pressure and tube flow stabilization circuit and protection circuit.

The principle of many characterization devices is to make electrons interact with substances that need to be detected, excite secondary electrons, or make atomic level transitions and backtrips, and release characteristic energy.

Total reflection X-ray fluorescence (TXRF) is a surface element analysis technique commonly used to analyze particles, residues, and impurities on smooth surfaces.

Grazing-incidence X-ray diffraction (GI-XRD) is a kind of X-ray diffraction technique, which is different from the traditional XRD experiment, mainly by changing the Angle of X-ray incidence and the orientation of the sample.
