GRAPHENE ELECTRONIC CIRCUITS WITH ATOMIC PRECISION

GRAPHENE ELECTRONIC CIRCUITS WITH ATOMIC PRECISION

Essential electronic components, such as diodes and tunnel barriers, can be incorporated in single graphene wires (nanoribbons) with atomic precision. The result is a working electronic device that could be used in Graphene-based electronic switches with extremely fast operational speeds. Chemists at Utrecht University made this discovery together with their colleagues at TU Delft and […]

How to Select a Voltage Regulator

How to Select a Voltage Regulator

All electronics projects need power. Power can come from either stored energy in a battery, or directly from mains AC voltage or DC power from renewable sources such as solar energy. Power Management ICs (PMICs)help manage the power requirements in a system including scaling voltages, battery charging, and DC-DC conversion. Choosing the right PMIC can make

WATER SPLITTING WITH SOLAR ENERGY

WATER SPLITTING WITH SOLAR ENERGY

Using solar energy to split water provides an efficient way for large scale renewable energy conversion and storage. A group of researchers from TUDelft and AMOLF have successfully developed an efficient and stable photo-electrode that could improve water splitting with solar energy. This photoelectrode absorbs light and directly decomposes water into hydrogen and oxygen. In addition to the efficiency, the system is

SMALLEST SATELLITE EVER SENT OPERATED IN ORBIT BY BREAKTHROUGH STARSHOT

SMALLEST SATELLITE EVER SENT & OPERATED IN ORBIT BY BREAKTHROUGH STARSHOT

Breakthrough Starshot is a research and engineering project by Breakthrough Initiatives to develop a proof-of-concept fleet of light sail spacecraft, named StarChip, capable of making the journey to the Alpha Centauri star system, 4.37 light-years away, at speeds between 15% and 20% of the speed of light, taking between 30 and 20 years to get there, respectively, and about 4 years to notify Earth of a successful arrival.

BISMUTH OXYIODIDE BIOI—A NON TOXIC ALTERNATIVE TO SOLAR CELLS

BISMUTH OXYIODIDE (BIOI)—A NON-TOXIC ALTERNATIVE TO SOLAR CELLS

28 July, 2017Rik 1632 0 Bismuth is considered as a “green-element” and bismuth-based compounds are gaining attention as potentially non-toxic and defect-tolerant solar absorbers. The researchers of the University of Cambridge and the United States developed theoretical and experimental methods to show that bismuth, which sits next to lead (Pb) on the periodic table, can be used to make

NEXT GENERATION SOLAR CELL THAT CAN CAPTURE NEARLY ALL ENERGY OF SOLAR SPECTRUM

NEXT GENERATION SOLAR CELL THAT CAN CAPTURE NEARLY ALL ENERGY OF SOLAR SPECTRUM

Researchers developed a multijunction solar cell on a GaSb substrate that can efficiently convert the long-wavelength photons typically lost in a multijunction solar cell into electricity. This prototype cell has an efficiency of 44.5% which is higher than conventional solar cells. A GaAs-based cell is stacked mechanically with the GaSb-based materials to create a four-terminal, five
