Montmorillonite impregnated with bismuth nitrate has been found to be an excellent reagent for the synthesis of several nitro compounds of biological significance in high yield.

We propose that turning on the light can turn on the hot emotional system. Across six studies we show that ambient brightness makes people feel warmer, which increases the intensity of their affective response, including sensation seeking from spicy-hot foods, perception of aggression and sexiness (“hotness”) in others, and generating more extreme affective reactions toward positive and negativ...

Hurricane intensification has been studied by scientists for decades and one phenomenon that appears to always accompany the intensification is the presence of hot towers of cumulous clouds that stretches to 15 km high, touching the top of the troposphere (Figure 1a &b). The hypothesis of Hot towers was first proposed in 1958 by Riehl and Malkus (Anthes, 1999), who wrote in conclusion from thei...

In the era of Chandra and XMM-Newton, the detection (or nondetection) of diffuse and/or point-like X-ray sources within planetary nebulae (PNe) yields important, unique insight into PN shaping processes. Diffuse X-ray sources, whether due to “hot bubbles” or to collimated outflows or jets, allow us to probe the energetic shocks within PN wind interaction regions. Meanwhile, X-ray point sources ...
