More efficient Quantum Dots without Heavy Metals

a, Preparation of InP cores and InP/ZnSe/ZnS QDs with different morphology and shell thickness. The amounts of Se precursor for QD-1, QD-2 and QD-3 were 0.6 mmol, 1.2 mmol and 2.0 mmol, respectively, per 10 ml of solvent. The estimated size, based on inductively coupled plasma-atomic emission spectroscopy (ICP-AES) data, was projected on the STEM image of each QD. b, Ultraviolet–visible absorption spectra of the aliquots, taken during the InP core synthesis. a.u., arbitrary units. c, Photoluminescence spectra of QD-1′ (prepared without HF addition), QD-1, QD-2, QD-3, QD-1R, QD-2R and QD-3R. Inset, photograph of QD-1′ (no HF) and QD-3 taken under 365 nm illumination. d–i, STEM images of QD-1, QD-1R, QD-2, QD-2R, QD-3 and QD-3R (scale bar, 20 nm)...

First-of-a-kind Electro-Optical Device provides solution to faster and more energy efficient Computing Memories and processors

The team has created a first-of-a-kind electro-optical device that bridges the fields of optical and electronic computing.

The first ever integrated nanoscale device which can be programmed with either photons or electrons has been developed by scientists in Harish Bhaskaran’s Advanced Nanoscale Engineering research group at the University of Oxford.

In collaboration with researchers at the universities of Münster and Exeter, scientists have created a first-of-a-kind electro-optical device which bridges the fields of optical and electronic computing. This provides an elegant solution to achieving faster and more energy efficient memories and processors.

Computing at the speed of light has been an enticing but elusive prospect, but with this development it’s now in tangible pro...

Detecting and Directing Single Molecule Binding Events on H-Si(100) with Application to Ultradense Data Storage

Scientists have added a crucial tool to the atomic-scale manufacturing toolkit with major implications for today’s data driven—carbon intensive—world, according to new research from the University of Alberta in Canada.

“Computers today are contributing one gigatonne of carbon emissions to the atmosphere, and we can eliminate that by enhancing the most power-hungry parts of conventional computers with our atomic-scale circuitry,” said Robert Wolkow, professor in the University of Alberta’s Department of Physics a Principal Research Officer at the National Research Council of Canada’s Nanotechnology Research Centre, and chief technical officer of Quantum Silicon Inc, a...

Psychosensory Electronic Skin Technology for Future and Humanoid development

Scientists have developed electronic skin technology for robots or electronic devices to feel pain through sense of touch. Expected to be applied in humanoid that needs 5 human senses and patients wearing prosthetic hands.

The attempt to mimic human’s five senses led to the development of innovative electronic devices such as camera and TV, which are inventions that dramatically changed human life. As a result, many scientists are continuously performing research to imitate tactile, olfactory, and palate senses and tactile sensing is expected to be the next mimetic technology for various reasons...
