Short‐Wavelength Infrared Imaging with Organic Photodetectors Based on Non‐Fullerene Acceptors with Detection above 1200 nm

Advanced Materials, EarlyView.
Solution‐processed organic photodetectors (OPDs) based on two novel low band gap non‐fullerene acceptors BZIC‐2F and BZIC‐2Cl, when blended with common polymer donor P3HT, extend detection range beyond 1200 nm with superior performance, rivaling costly inorganic sensors and past literature.

Non-Foster Impedance Wideband Matching Technique for Electrically Small Active Antenna

International Journal of Antennas and Propagation, 2013
This paper investigates a non-Foster wideband circuit matching technique for an electrically small antenna (ESA). By introducing a negative impedance convertor into an active network, the active network can obtain an equivalent input gain at input port ...

Thermally Modulated Metasurface Sensor for Dynamic and Time‐Resolved Isolation of Extracellular Vesicles

Advanced Materials, EarlyView.
A thermally adaptive plasmonic metasurface, functionalized with poly(N‐isopropylacrylamide) (PNIPAM) and anti‐CD63 antibodies, enables precise, on‐demand capture and release of extracellular vesicles (EVs). Delivering high recovery, improved purity, and intact vesicle structure, the platform offers a versatile, label‐free solution for real‐time EV ...

On Rapid Re-Design of UWB Antennas with Respect to Substrate Permittivity

Metrology and Measurement Systems, 2016
Re-design of a given antenna structure for various substrates is a practically important issue yet non trivial, particularly for wideband and ultra-wideband antennas. In this work, a technique for expedited redesign of ultra-wideband antennas for various

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

Advanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
