LED display heat dissipation design

Led display work under high temperature conditions for a long time will cause the lamp beads to decay and reduce the lifespan. At the same time, the probability of failure rate of electronic devices will increase rapidly. As a result, the display reliability is reduced. So solving the problem

DNA machine or can be used to make nano-sensors

In a new study, researchers from Shanghai Jiao Tong University in China, Emory University and Purdue University in the United States used DNA to construct simple machines that consist of DNA arrays made up of DNA Modular DNA structural units that switch between two different shap
