Structural Studies of Giant Empty and Endohedral Fullerenes

Frontiers in Chemistry, 2020
Structure elucidations of giant fullerenes composed of 100 or more carbon atoms are severely hampered by their extremely low yield, poor solubility and huge numbers of possible cage isomers.

First‐Principles Structure–Activity Relationship Insights Into Phenolic Scaffolds: QSAR Modeling and Drug‐Likeness Screening

Advanced Theory and Simulations, EarlyView.
Integrated machine learning framework for phenolic derivatives: classification (toxicity) and regression (logP) models identify top drug‐like compounds. Random Forest outperformed for toxicity, while Linear Regression best predicted logP. A weighted scoring approach prioritized five safe, lipophilicity‐optimized candidates, supporting rational ...

Closed‐Loop Bioelectronic Artificial Pancreas Patch for Continuous Monitoring and Regulation of Blood Glucose in Diabetic Rats and Pigs

Advanced Science, EarlyView.
A closed‐loop bioelectronic artificial pancreas patch is presented for glucose monitoring and regulation. Utilizing transiently dissolvable microneedle arrays integrated with microtube arrays, the patch efficiently delivers insulin into interstitial fluid, eliminating the need for external long needles. In diabetic pigs, it demonstrates excellent blood

Chlorination of Polyamides and Characteristics of the Chlorinated Polymers.

Sen'i Gakkaishi, 2000
Chlorination and dechlorination of aliphatic and aromatic polyamides such as nylon 66 and poly-m-phenyleneisophthalamide (PMPIPA) were studied. Chemical structures and properties of the chloro-polyamides were examined by means of Cl-analysis, IR and 1H NMR spectroscopies, viscometry, and wide-angle X-ray diffraction (WAXD).

Vacancy Engineered Zero‐Valent Iron Steer Hydrogen Spillover toward Per‐ and Polychlorinated Organics Rapid Complete Dechlorination

Advanced Science, EarlyView.
Zero‐valent iron with a vacancy‐rich carbon shell and lattice Cu doping in Fe0 cores generates a dechlorination mechanism combining enhanced electron transfer and modulated H* spillover, which significantly lowers the energy barrier for dechlorinating low‐chlorinated intermediates, accelerates C─Cl bond dissociation, and then delivers breakthrough ...

The Separation of the Element Chlorine into Normal Chlorine and Meta-Chlorine, and the Positive Electron [PDF]

Nature, 1920
IN commenting on a letter under the above heading from Prof. Harkins in NATURE of April 22 last, I remarked that his assumption that “the hydrogen nucleus or the positive electron has, according to these papers, a weight, and presumably a mass, of 1.000, on the basis of oxygen as 16.000,” was contradicted by experiment.
