New azidotetrazoles: structurally interesting and extremely sensitive.

The treatment of triaminoguanidinium chloride with two equivalents of sodium nitrite under acidic conditions, followed by the cyclization with stoichiometric amounts of either sodium hydroxide solution or solid sodium carbonate yielded 1-amino-5-azidotetrazole (1), 5-azido-1-diazidocarbamoyltetrazole (2), and 1-(aminoazidocarbamoyl)-5-azidotetrazole (3). The three novel compounds could be isola...

Polarization-sensitive optical phenomena in semiconducting and metallic nanowires

An analysis is presented of optical absorption and emission in semiconducting, metallic, and mixed coreshell nanowires are considered theoretically. Due to image forces caused by the difference in dielectric constants between nanowires and their environment, absorption and emission coefficients are different for light polarized parallel or perpendicular to the nanowire axis. As a result, the in...

Gardening and the Feeble-Minded

as the outdoor activities of mental defectives in institutions had previously been limited to elementary jobs, such as sweeping the paths, and generally acting as labourers to the staff engaged on the ornamental gardens. It was recognised that, for many years, patients in large mental institutions and colonies had been employed on farms, pig feeding, etc.; some of them had been taught to milk c...
