Hierarchical Sn-Beta was prepared by a hydrothermal postsynthesis method. It shows higher catalytic activity for conversion of glucose to alkyl lactate than microporous Sn-Beta hydrothermally synthesized in fluoride media.

Hierarchical Sn-USY zeolites are highly active and selective for the conversion of dihydroxyacetone to methyl lactate.

A novel biphasic layered Na0.62Ni0.33Mn0.62Sb0.05O2 cathode is introduced which can be easily synthesized via solid-state reaction method. Compared with its monophasic counterpart Na0.67Ni0.33Mn0.67O2, biphasic Na0.62Ni0.33Mn0.62Sb0.05O2 displays smoother (dis)charge profile, superior...

The authors report the result of a preliminary study concerning the elimination of organic impurities such as microbes or bacteria in KDP growth solution. A chemical preservative (antiseptic mercury, Hg), was successfully employed for the sterilization of bacteria and microbes, which can be eliminated from the beginning to the end of the growth process. The preservative does not contaminate the solution or the as-grown KDP crystals.

Hidden services are a feature of Tor(The Onion Router)[1]. It provides anonymity for the service requester while maintaining the anonymity of the service provider. Since it is quite difficult to trace back and locate both parties in the communication, the criminals use hidden services mechanisms to construct various illegal activities in the darknet, which has brought adverse effects to society. In order to prevent the abuse of Tor hidden services, the discovery and analysis of hidden services are particularly important. The aim of this survey paper is to review and compare the literature of the past five years, provide the readers with methods for discovering tor hidden services, along with the various content analysis methods developed and proposed from time to time. we explain their key ideas and show their interrelations.
