• Pressure working properties of magnesium alloys

  The pressure machinability of metallic materials depends on two relatively independent factors of the material: the machinability related to stress state (SOS) and the machinability inherent in the material itself. The machinability of SOS depends on the geometrical relationship of the deformation zone, and the workpiece is in three-dimensional stress state in the deformation zone.

• High purity quartz -"Giant Panda" in silica

  Quartz is one of the most common minerals in nature. It is the scientific name of a group of minerals composed of silica​ (SiO2). It is widely used in glass, architecture, precious jade and stone decoration and other traditional industries. Since the 1960s, computer, new materials, new energy and other emerging technologies have put forward higher requirements on the purity of quartz products, and the concept of high purity quartz was born.

• The perovskite material can be used to build artificial retinas  

  Researchers have built an artificial retina made of perovskite that can detect light in a similar way to the human eye. In tests, the device was even able to recognize handwritten numbers.The eyes of humans and other mammals work thanks to light-sensitive cells in the retina, rods and cones, which absorb incoming photons and send electrical signals to the brain. In this study, the researchers set out to simulate this process in a man-made device.
