Effect of concentration of trimethylchlorosilane (TMCS) and hexamethyldisilazane (HMDZ) silylating agents on surface free energy of silica aerogels.

J. Colloid. Interface Sci. 356(1) , 298-302, (2011)

The surface free energy of a solid determines its surface and interfacial behavior in processes like wetting and adhesion which is crucial for silica aerogels in case of organic liquid absorption and ...

Europium bis(dimethylsilyl)amides including mixed-valent Eu3[N(SiHMe2)2]6[μ-N(SiHMe2)2]2.

Dalton Trans. 43(46) , 17324-32, (2014)

Trivalent Eu[N(SiHMe2)2]3(THF)2 can easily be synthesized by applying a routine salt metathesis protocol (EuCl3(THF)2 and 3 equiv. of Li[N(SiHMe2)2] in n-hexane) which crystallizes isotypically to its...

A facile two-step dipping process based on two silica systems for a superhydrophobic surface.
