The adults of Calochromini with male flabellate antennae were studied. Two new Calochromus Guérin-Méneville, 1833 species with flabellate antennae, C. kelantanensis spec. nov. and C. harauensis spec. nov. are described. Dumbrellia Lea, 1909 (Calochromini) is proposed as a new junior synonym of Plateros Bourgeois, 1879 (Lycinae: Platerodini). Flabellochromus Pic, 1925 is transferred to Calochrom...
Sinopla canaliculus Reed, 1898 is revalidated and illustrated for first time. Pseudosinopla n. gen. (Blaudusinae: Lanopini) is erected to place S. canaliculus Reed, 1898. A key to Chilean Lanopini genera is included.
End-functionalized polyethylene oxides containing cleavable acetal and clickable azide terminal groups (PEO-acetal-N3 and N3-acetal-PEO-acetal-N3) were obtained by the reaction between commercially available PEOs and 2-chloroethyl vinyl ether using pyridinium p-toluenesulfonate. This results in acetal-linkages which can be further functionalized by nucleophilic displacement with sodium azide. B...

Most probably, it was the era that was not on their side. In the time period wherein most eponyms were given, women had almost no access to higher education. There are a few exceptions of course, such as Marie Curie or V...

This is a surgical procedure in children who suffer from hypoxia because of a congenital cardiac malformation. Because of this affliction, they are blue. Less known is the fact that dr. Taussig also played a crucial role in the prohibition of thalidomide in the USA, the drug that had been responsible ...
