Building a system of issuing and managing diplomas and certificates

The authors of Ho Chi Minh City University of Technology have applied blockchain technology to build a system for issuing and managing diplomas and certificates. To issue a certificate, the training institution registers an account and logs in to the system to create embryos. After filling in the student’s information, the course, etc., the training institution can print it to issue a certificate or issue a digital certificate. Each certificate is issued with a QR code, which can be looked up and verified on the student’s information and the certificate on the mobile application. The system helps to reduce time and costs for training institutions and quickly detect cases of tampering. The glue that helps regenerate nerve cells Researchers at the University of Georgia (USA) have studied a special glue in the form of hydrogel to aid in the recovery of brain cells. The researchers implanted the hydrogel into mice with traumatic brain injury. After 20 weeks, the mouse’s cell repair process was enhanced, motor function improved. The results showed that this glue not only protects tissues from damage, but also regenerates functional neurons at the affected site. The results of the study hold promise for the medical profession to prevent cognitive decline or tissue loss in patients with traumatic brain injury. New battery development Russian scientists have developed a new type of battery that can be charged about 10 times faster than commonly used lithium-ion batteries. Tests show that the new battery can work well in emergency charging situations and in low-temperature environments. The new battery is also safer for the environment.
