We have combined the velocity map imaging technique with time-of-flight measurements to study the surface photochemistry of KBr single crystals. This approach yields 3-dimensional velocity distributions of Br atoms resulting from 193 nm photodesorption. The velocity distributions indicate that at least two non-thermal mechanisms contribute to the photodesorption dynamics. Our experimental geome...

The formation mechanism of the thermodynamically unstable calcite phase, very high Mg calcite, in biological organisms such as sea urchin or corallina algae has been an enigma for a very long time. In contrast to conventional methods such as KBr pellet Fourier Transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD), FTIR microspectroscopy (FTIRM) provides additional information about...

Liquid metal battery (LMB) with low cost, excellent cycle performance and flexible scalability is developed as a promising solution for large-scale energy storage. However, the high melting point of electrolyte necessitates an elevated operating temperature, which provokes aggravated hermetic seal corrosion issues, seriously inhibiting advancement LMBs. Herein, we elaborately design novel LiCl–...

This paper reports a one-pot synthesis of the title bromides from both activated and deactivated iodoarenes which are first oxidized with anhydrous NaBO3·H2O/Ac2O/conc.H2SO4 liquid mixtures, then coupled in situ with benzene and activated arenes and, finally, precipitated out with a KBr solution; this method is easy, cheap, safe and fairly effective.

There has been substantial recent interest in integrating knowledgebased reasoning (KBR) and case-based reasoning (CBR) within a single system due tothe potential synergisms that could result. Here we describe our recent work investigatingthe feasibility of a combined KBR-CBR application-independent system for interpretingmulti-episode stories/narratives, illustrating it with an...
