一般描述
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.
应用
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

This study sought to hypothesize that elevated B-type natriuretic peptide (BNP) could act as an endogenous neprilysin inhibitor. A hallmark of acute decompensated heart failure (ADHF) is the overproduction of natriuretic peptides (NPs) by stretched cardiomyocytes. Various strategies have been

Better understanding of the mechanism is important for exploring the potentials of a preconcentration method. In this work, we show for the first time that the HF etched porous junction on a fused silica capillary behaves not only as a
