一般說明
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.
應用
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.

We identified easily obtained baseline characteristics associated with outcomes in patients with chronic heart failure (HF) and elevated heart rate (HR) receiving contemporary guideline-recommended therapy in the SHIFT trial, and used them to develop a prognostic model. We selected the

Although simulation studies show that combining multiple breeds in one reference population increases accuracy of genomic prediction, this is not always confirmed in empirical studies. This discrepancy might be due to the assumptions on quantitative trait loci (QTL) properties applied

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
