TL;DR: In this paper, a method for preparing a titanium oxide gel, characterized by comprising the following steps: forming water solution containing titanium by using inorganic titanium resource, settling the water solution to get titanium dioxide gel, which can be used in low temperature (concluding room temperature) or high temperature (7-400 Deg C).
Abstract: The invention provides a method for preparing a titanium oxide gel, characterized by comprising the following steps: forming water solution containing titanium by using inorganic titanium resource, settling the water solution containing titanium to get titanium oxide gel. The produced titanium oxide gel can be used in low temperature (concluding room temperature) or high temperature (7-400 Deg C), and be used for preparing the coating for crystallizing titania photocatalyst in common temperature (about 25 Deg C) or low temperature (above 7 Deg C), and the cost is low; the product is also be used as the bottom of the multiplayer coating to strengthen the adhesion of the coating with body. The invention also provides a method for preparing crystal titania gei and the coating of the titania photocatalyst under room temperature.

TL;DR: In this article, the authors proposed an arrangement method of dynamic proxy of mobile VPN and its system, which can build the virtual private network between at least one external network and one internal network and can reach the safe roaming of a mobile node in said external network.
Abstract: The invention relates to arrangement method of dynamic proxy of mobile VPN and its system, which can build the virtual private network between at least one external network and one internal network and can reach the safe roaming of at least one mobile node in said external network. The invention uses the external local proxy which can be dynamically arranged near the mobile node in said roaming external network as the register proxy of said mobile node, to make the mobile node only need to register at said external local proxy when it is roaming in the same external network, without the registering at the internal local proxy (i-HA) of said internal network-the Internet Engineering Task Force. So the handoff delay and the end to end delay between proxies when in roam can be reduced most while the invention can fully combine the VPN of internet communication security protocol safe control.
