Descripción general

HF is a colorless inorganic acid. Hydrogen fluoride may be formed by reacting calcium fluoride and sulfuric acid at 200oC. The fluoride in the acid has very high affinity to silicon, making it useful in etching or removal of silicon.

Aplicación

Industrial uses of HF include etching or polishing glass, ceramics and silicon surfaces. HF may be used to etch silica capillaries for it behave as a filter and an integrated nanofluidic device for the stacking of DNA and proteins. Dentin and ceramic inlays may be etched with HF for better adhesive bonding. Nanohydroxyapatite was etched with 0.5%HF prior to measuring its morphological and mechanical properties.

Muscle sympathetic activation in heart failure with reduced ejection fraction (HFrEF) has been attributed, on the basis of multiunit recordings, to attenuated inhibitory feedback from stretch-sensitive cardiopulmonary mechanoreceptors. However, such preparations integrate 2 populations of single units exhibiting directionally opposite
