In this study, a self-assembled monolayer (SAM) of methoxy-poly (ethylene-glycol)-silane (mPEG-sil) was used to modify the silicon dioxide surface of polysilicon nanodevices (PNDs) to act as a passivation layer that inhibits nonspecific binding of proteins and reduces localized Joule heating power. Selective modifications of 3-aminopropyltrimethoxysilane (APTMS), NHS-biotin and dye-labeled Stre...
In this work, perovskite solar cells (PSCs) with CH3NH3PbI3-x Cl x as active layer and spiro-OMeTAD as hole-transport media have been fabricated by one-step method. The methylammonium iodide (CH3NH3I) solution with different concentrations is used to modify the interface between mesoporous TiO2 (meso-TiO2) film and CH3NH3PbI3-x Cl x perovskite layer. Several techniques including X-ray diffracti...
We have discovered that films of carbon single wall nanotubes (SWNTs) make excellent back contacts to CdTe devices without any modification to the CdTe surface. Efficiencies of SWNT-contacted devices are slightly higher than otherwise identical devices formed with standard Au/Cu back contacts. The SWNT layer is thermally stable and easily applied with a spray process, and SWNT-contacted devices...
to minimize the risk of embolic events, several protection strategies have been introduced. we have evaluated the short-term outcome of patients who underwent carotid stenting with the routine use of cerebral protection devices. in our center, 36 successful carotid stenting procedures (of 38 attempted) were performed in 37 patients (23 men; age mean [sd] 667 years). cerebral protection involv...
Sodium-ion batteries (SIBs) are emerging as potential stationary energy storage devices due to the abundance and low cost of sodium. A simple and energy efficient strategy to develop electrodes for SIBs with a high charge/discharge rate is highly desirable. Here we demonstrate that by surface modification of Ge, using electroless deposition in SbCl3/ionic liquids, the stability and performance ...
Detection and quantification of biological and chemical species are central to many areas of healthcare and the life sciences, ranging from diagnosing disease to discovery and screening of new drug molecules. Semiconductor nanowires configured as electronic devices have emerged as a general platform for ultra-sensitive direct electrical detection of biological and chemical species. Here we desc...
