A variety of optical applications rely on the absorption and reemission light. The quantum yield this process often plays an essential role. When deviates from unity by significantly less than 1%, such as luminescent concentrators refrigerators become possible. To evaluate high performance, we develop a measurement technique for luminescence efficiency with sufficient accuracy below one part per thousand. Photothermal threshold is based quantization light to minimize overall uncertainty....

The interface between cells and nonbiological surfaces regulates cell attachment, chronic tissue responses, ultimately the success of medical implants or biosensors. Clinical laboratory studies show that topological features surface profoundly influence cellular responses; for example, titanium with nano- microtopographical structures enhance osteoblast attachment host–implant integration as compared to a smooth surface.

Organic electrochemical transistors (OECTs) show great promise for flexible, low-cost, and low-voltage sensors aqueous solutions. The majority of OECT devices are made using the polymer blend poly(ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS), in which PEDOT is intrinsically doped due to inclusion PSS. Because this intrinsic doping, PEDOT:PSS OECTs generally operate depletion mode, results a higher power consumption limits stability. Here, straightforward method de-dope...
