Microelectronics-embedded channel bridging and signal regeneration of injured spinal cords

Due to the difficulty in spinal cord regeneration with biological methods, the microelectronic neural bridge, a new concept based on microelectronic technology, is presented. The microelectronic system has been realized in the forms of hybrid and integrated circuits. The integrated circuits for neural signal detection, stimulation, and regeneration are realized in a CMOS process. In animal experiments with 100 toads, 48 rats, and 3 rabbits, nerve signals have been successfully detected from spinal cords and sciatic nerves, and functional electrical stimulation has been carried out for spinal cords and sciatic nerves. When the microelectronic system is bridged between the controlling and stimulated nerve, the relevant motion of legs and nerve signal waveforms, which are stimulated by the evoked or spontaneous nerve signal through such a system, have been observed. Therefore, the feasibility of the presented method was demonstrated.     

Preparation and kinetic analysis of Li4SiO4 sorbents with different silicon sources for high temperature CO2 capture

Using diatomite and analytical pure SiO2 as silicon sources,Li4SiO4 sorbents for high temperature CO2 capture were prepared through solid-state reaction method.Phase composition was analyzed by X-ray diffraction,and the CO2 absorption capacity and absorptoin-desorption performance were studied by the simultaneous thermal thermogravimetric analyzer(TG-DSC).The results showed that silicon source had an important influence on CO2 absorption properties.The kinetic parameters for the chemisorption and diffusion processes were obtained by the isothermal study for different silicon sources.The results showed that the activation energies for these two processes were estimated to be 105.427 and 35.928 kJ/mol for the sample with analytical pure SiO2(AS).While for the sample with diatomite(DS),the activation energies for these two processes were estimated to be 78.500 and 20.439 kJ/mol,respectively.
