Interface‐Defect Synergy Engineering of Amorphous Ga2O3 for Voltage‐Tunable Dual‐Mode Optoelectronic Devices: Self‐Powered Imaging and Neuromorphic Vision

Advanced Functional Materials, EarlyView.
An interface‐defect co‐engineered strategy enables bias‐programmable integration of self‐powered photodetection and low‐power synaptic functionalities within a single‐material amorphous Ga2O3 device. This design achieves reversible switching via voltage modulation, supporting high‐contrast imaging and visual memory, and demonstrates a neuromorphic ...

High‐Performance n‐Type Organic Thermoelectrics Enabled by Control Over Microstructure, Orientation and Contact Plane in Naphthalenediimide‐Bithiazole‐Copolymer Films

Advanced Functional Materials, EarlyView.
Effective control over the crystalline contact plane and microstructure of a naphthalenediimide‐bithiazole copolymer enables high‐performance n‐type thermoelectrics. While rubbing alignment induces a detrimental edge‐on orientation, subsequent solvent vapor‐induced re‐orientation facilitates a favorable mixed face‐on/edge‐on morphology.

Synthesis and application of isocyanates radiolabeled with carbon-11.

Chemistry – A European Journal, 2011
AbstractCarbon‐11 labeled isocyanates are efficiently prepared by dehydration of [11C]carbamate salts, which in turn are easily formed from cyclotron‐produced [11C]CO2 and amines in the presence of a CO2 fixation agent. The [11C]isocyanates are useful radiosynthons for the synthesis of a variety of [carbonyl‐11C]‐labeled asymmetrical ureas and ...

K-capture in carbon 11

Philosophical Magazine, 1957
Abstract K-capture in 11C has been observed and the K/β+ ratio found. Comparison with theory leads to a value for the ratio of the Fermi coupling constants. Proportional counters were employed with a gaseous source, and two anti-coincidence systems were used, in turn, to reduce wall effects.
