Fluorolytic sol–gel synthesis with aqueous HF results in highly disordered, nanoscopic magnesium hydroxide fluorides with very large BET surface areas, low carbon contents, and adjustable stoichiometries. MgFx(OH)(2–x) materials that can withstan

19 F MAS NMR signals of a variety of X-ray amorphous magnesium hydroxide (oxide) fluorides (MgF x (OH(R)) 2− x (0 x ≤ 2)) prepared using different synthesis routes are compared and assigned. Relations between their 19 F signal positions and local

The thermal treatment of sol−gel derived aluminum hydroxide fluorides leads to new, X-ray amorphous, macroporous aluminum oxide-hydroxide fluorides. Followed by EA, DTA-TG, XPS, FT-IR, NH3-TPD, BET, XRD, and MAS NMR, it can be shown that the simpli

The influence of fluoride doping, sonication and milling on the phase transformation of pseudoboehmites to corundum was explored. Followed by XRD and MAS NMR, it can be shown that the crystal structure of the dopant as well as the particle size of th

A new synthesis route to nonhydrated, X-ray amorphous aluminum hydroxy fluorides was explored by sol−gel synthesis with aqueous hydrofluoric acid. Followed by XRD, MAS NMR, and DTA-TG, it can be shown that the product composition after thermal anne

Hexa- and nonanuclear titanium complexes were obtained by self-assembly of titanium(IV)-tert-butoxide and D-mandelic acid. Suitable single crystals of these complexes were characterized by X-ray structure analysis. When used with these complexes, ald

Two-photon calcium imaging is a powerful means for monitoring the activity of distinct neurons in brain tissue in vivo . In the mammalian brain, such imaging studies have been restricted largely to calcium recordings from neurons that were individual
