Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing
Advanced Optical Materials, EarlyView.An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

Global change and biodiversity loss: Some impediments to response [PDF]
Discussed here are the effects of anthropogenic global climate change on biodiversity. The focus is on human responses to the problem. Greenhouse warming-induced climate change may shift agricultural growing belts, reduce forests of the Northern ...

Advanced Sensor Research, EarlyView.A flexible electrochemical sensor platform can enable continuous, real‐time monitoring of salivary glucose for applications confined to spaces such as the oral cavity. Surface modifications with Prussian blue, chitosan, and zwitterionic polymers enhance sensitivity, selectivity, and antiadherent performance.

Are textbook references to Darwin close to extinction? [PDF]
, 2008 The textbooks used to teach GCE A-level biology 30 years ago tended to concentrate on traditional zoology and botany, with just a passing reference to evolution. As biology established itself as a new discipline, books (and syllabuses) began to take an

Biological mass extinctions on planet Earth
, 2010 [ES]: Tanto acontecimientos graduales como catastróficos han estado implicados a las extinciones masivas en el planeta Tierra. A pesar de que la mayor extinción masiva, según restos fósiles identificados actualmente, fue la Gran Mortandad (del inglés, “Great Dying”), la mayor de todas las extinciones masivas en el planeta Tierra debió haber sido la ...
