Research on human-computer interaction technology based on electrical detection technology

Han H-P., Tang K., Lang X-Q., Chen X., Beijing Institute Technology, CN

Human-computer interaction (HCI) technology has emerged as a crucial dimension of computer science and information industry. HCI with keyboard and mouse has started to lose ground, as people tend to harness the power of body [...]

An Enzyme-Responsive Controlled Release Drug Delivery System Based on Mesoporous Silica and DNA

Zhang X., Wu Z., Hefei Institutes of Physical Science, Chinese Academy of Sciences, CN

An efficient enzyme-responsive controlled release drug delivery system was fabricated using functional mesoporous silica nanoparticles (FMSN) encapsulated with the single-stranded DNA. Based on the electrostatic interactions between FMSN and single-stranded DNA, the DNA coating could [...]

Effect of matrix components with low thermal conductivity and density on performances of cement-EPS/VM insulation mortar

Chen M., Wang S., Lu L., Zong W., Zhao P., Gong C., University of Jinan, CN

Cement-EPS/ vitrified microsphere (VM) insulation (CEV) mortar was prepared by using suphoaluminate cement as cementitious material, EPS and VM as insulation aggregates. The performance of matrix without insulation aggregates not only could determine the mechanical [...]
