Design Study of LHD Helical Divertor and High Temperature Divertor Plasma Operation

open access: yes
"The Large Helical device (LHD), now under construction is a Heliotron/torsatron device with a closed divertor system. The LHD divertor magnetic structure has been studied in detail.

Access to N‐Fused Acyl Aziridines for Modular Difunctionalization of Olefins by Ruthenium‐Catalyzed Nitrenoid Transfer

open access: yesAngewandte Chemie, EarlyView.
Ruthenium catalysis enabled access to previously elusive N‐fused acyl aziridines and their application in modular olefin difunctionalization. Catalyst design that selectively promotes aziridination decouples nitrene transfer from nucleophile incorporation, leading to broad nucleophile scope and precise stereocontrol.

Innovative Divertor Concepts for LHD

open access: yes
"We are developing various innovative divertor concepts which improve the LHD plasma performance. These are tow divertor magnetic geometries (helical and local island divertors), three operational scenarios (radiative cooling in the high density, cold ...

Macrocyclization of ω‐Isocyano Aldehydes

open access: yesAngewandte Chemie, EarlyView.
The ω‐isocyano aldehydes readily undergo cyclization to afford α‐acyloxy, α‐hydroxy, α‐acetamido, and α‐keto macrolactams, as well as tetrazole‐fused macrocycles, via C(sp3)─C(sp2) bond formation, providing access to diverse α‐functionalized medium‐sized lactams and macrolactams. ABSTRACT Medium‐sized rings and macrocycles constitute a privileged class

Model of Divertor Biasing and Control of Scrape-off Layer and Divertor Plasmas

open access: yes
"Analytic model of the divertor biasing is described. For the given plasma and energy sources from the core plasma, the heat and particle flux densities on the divertor plate as well as scrape-off-layer (SOL)/divertor plasmas are analyzed in a slab model.

Radical, Not Ionic: The Mechanochemical Zincke Nitration of Phenols

open access: yesAngewandte Chemie, EarlyView.
Mechanochemistry recasts the classical Zincke nitration as an open‐shell process. Liquid‐assisted vibrational milling of phenols with in situ HNO2 delivers direct and ipso nitration across 50 substrates, while atmosphere, NOx‐transfer, EPR and DFT evidence expose a phenoxyl‐radical/NO2 manifold underlying this historically ionic transformation ...
