Helical Single Crystals of Porous Hydrogen‐Bonded Organic Frameworks as a Candidate for Morphologically Functional Organic Materials

open access: yesAngewandte Chemie, EarlyView.
Helical‐shaped crystals of a hydrogen‐bonded organic framework (HOF) with permanent porosity have been developed. The helical HOF shows expansion and contraction, respectively, upon desorption and adsorption of solvents. Moreover, doping of additive molecules can modulate the photophysical properties and morphology of the helical HOF, showing the ...

NHC‐Copper(I)‐Mediated Functionalization of White Phosphorus

open access: yesAngewandte Chemie, EarlyView.
White phosphorus is functionalized by N‐heterocyclic carbene supported copper(I) complexes through redox‐neutral steps. Treatment of the resulting complexes with electrophiles releases the ligands from the metal center as asymmetrically substituted organophosphorus butterfly compounds.

A High‐Voltage Membrane‐Free Li–Organic Hybrid Flow Battery Using Eutectic Lithium Chemistry

open access: yesAngewandte Chemie, EarlyView.
A high‐voltage (3.6 V) membrane‐free Li–organic hybrid flow battery is enabled by a deep‐eutectic lithium electrolyte composed of trifluoroacetamide (TFAD) and LiPF6, paired with a dichloromethane (DCM) catholyte containing phenothiazine (PTZ). The TFAD/LiPF6 eutectic provides fast Li+ transport and stable Li‐metal cycling, while the immiscible TFAD ...

Preliminary breakdown pulses of cloud-to-ground lightning in winter thunderstorms in Japan

Journal of Atmospheric and Solar-Terrestrial Physics, 2013
Abstract Preliminary breakdown pulses (PBP) of 26 positive and 104 negative cloud-to-ground (CG) lightning flashes observed in winter thunderstorms in Hokuriku region of Japan are analyzed. Pulses in PBP train are mainly bipolar. Zero-crossing time of each pulse is about 7 us and total duration of each pulse train is about 1 ms.

Perbedaan karakteristik pulsa peter narrow bipolar dengan Preliminary breakdown

open access: yes, 2017
Narrow Bipolar merupakan salah satu kejadian petir yang terjadi di dalam awan yang berlangsung sangat cepat dan memiliki kekuatan radiasi yang sangat kuat dibandingkan petir biasa. Preliminary Breakdown adalah deretan pulsa medan listrik yang terjadi beberapa milidetik sebelum Stepped Leader dan Return Stroke dimana dapat dilihat dari polaritas ...
