He is now calling for alternatives to needles to be developed for the transfer of solvents or reagents to make labs safer.1. He emptied a syringe containing dichloromethane (DCM) into a flask, but then accidentally pricked his finger with it. Vidal estimates about two drops, or less than 100μl of DCM, was left in the needle and that this entered the finger. A series of graphic photographs show what happened next – the journal article is accompanied by a warning that some may find the images (reproduced below) disturbing. Following the needlestick injury, it took around 15 minutes for a purple discoloration to spread over Nicolas’ finger. Nic...

The acquisition of the language for chemists including the training of the terminological system poses special difficulties and depends not only on its arrangement but as it was deduced from our experience in classes of chemistry, also on the presentation, and specifically the context it is presented in. Thus, the problem of systematization and presentation remains a current issue. The development of conceptual linguistics opens a new scope in arranging semantic vocabulary for teaching purposes. The lexical stock of the language is treated as the result of the division of knowledge into structures. The content of the frame, unlike that existing in the thematic vocabularies based on semantic fields, is based on the structure of the activity situation. But the learnin...
