TL;DR: In this paper , a facile route to dual single-atom nanozyme composed of Zn and Mo utilizing the non-covalent nano-assembly of polyoxometalates and supramolecular coordination complexes as the metal atom precursor, and the macroscopic amphiphilic aerogel as the supporting substrate was presented.
Abstract: We present a facile route to dual single-atom nanozyme composed of Zn and Mo utilizing the non-covalent nano-assembly of polyoxometalates and supramolecular coordination complexes as the metal atom precursor, and the macroscopic amphiphilic aerogel as the supporting substrate. The dual single-atom of Zn and Mo have high contents of 1.5 wt% and 7.3 wt%, which exhibit a synergistic effect and a peroxidase-like activity. The Zn/Mo site was identified as the main active center by X-ray absorption fine structure spectroscopy and density functional theory calculation. The detection of versatile analytes including intracellular H2O2, glucose in serum, cholesterol, and ascorbic acid in commercial beverages was achieved. The nanozyme had an outstanding stability and maintained its performance after one year's storage. This study develops a new peroxidase-like nanozyme and provides a robust synthetic strategy for single-atom catalyst by utilizing the aerogel as a facile substrate that is capable in stabilizing various metal atoms.

TL;DR: A text-book of Practical Organic Chemistry including Qualitative Organic Analysis by Dr Arthur I Vogel as mentioned in this paper, intended as a comprehensive laboratory manual for students of organic chemistry, gives a full and valuable description of organic chemical technique, details of preparation of more than six hundred compounds, and a scheme of qualitative organic analysis.
Abstract: DR VOGEL‘S books on analysis are widely used in teaching practical inorganic chemistry His new volume is intended as a comprehensive laboratory manual for students of organic chemistry It gives a full and valuable description of organic chemical technique, details of preparation of more than six hundred compounds, and a scheme of qualitative organic analysis There are appropriate notes on the preparative reactions described and on the properties of the various classes of organic compounds A curious omission is the almost complete absence of reference to quantitative organic analysis It seems to the reviewer that some practice at least in quantitative elementary analysis is of value in the student‘s training, even in these days when the fully fledged organic chemist hands his analysis specimens to the microanalyst for determinations which he is usually quite unable to carry out himself A Text-Book of Practical Organic Chemistry Including Qualitative Organic Analysis By Dr Arthur I Vogel Pp xxiii + 1012 (London, New York and Toronto : Longmans, Green and Co, Ltd, 1948) 42s net
