The micro-structural and physicochemical properties of the CuIMOF were systematically studied by the powder X-ray diffraction (PXRD), Single crystal X-ray diffraction (SCXRD), …
WebAug 30, 2024 · The growing needs for wearable health monitoring systems call for a high‐performance real‐time UV sensor to prevent skin diseases caused by excess UV exposure. To this end, here a novel self‐powered p‐CuZnS/n‐TiO2 UV photodetector (PD) with high performance is successfully developed (responsivity of 2.54 mA W−1 at 0 V … Webwell as selective enrichment. These expressions indicate that selectivity is regarded as something that can be graded. Methods have often been described in qualitative terms, such as having good selectivity or even high, excellent, or extreme selectivity. This qualitative use of the term has been discouraged.
WebJan 23, 2024 · Unlike the complex transformations of combustion, the halogenation of an alkane appears to be a simple substitution reaction in which a C-H bond is broken and a new C-X bond is formed. The chlorination of methane, shown below, provides a simple example of this reaction. CH 4 + Cl 2 + energy → CH 3 Cl + HCl.
