Non-Tariff barriers to trade [PDF]

open access: yesIntereconomics, 1977
Over the past three decades the non-tariff barriers to trade have grown in importance inversely to the import duties which have been lowered under GATT auspices. In the current GATT negotiations — the Tokyo round in which the contracting parties have been at work since the autumn of 1973 to solve the acute trade-political problems — non-tariff trade ...

Atmospheric Doping of Stretchable Polymer Semiconductors for Skin Electronics

open access: yesAdvanced Functional Materials, EarlyView.
An atmospheric doping system using oxygen molecules in air as dopants is introduced for stretchable polymer semiconductors. The chemisorbed oxygen molecules act as acceptor, lead to increase not only the hole concentration of the semiconductor film over two orders of magnitude (3.37 × 1017 cm−3) but also electrical properties of the field‐effect ...
