Figure 1: AC-DC, Basic Voltage External Power Supply
External power supplies (EPSs) are contained in a separate housing from the devices they are powering and contribute substantially to total global electricity consumption. As governments strive to address their ongoing environmental responsibilities, resolving the inefficiencies of power conversion has become

Today’s demand for high-performance, low-cost power conversion products is driven by consumer expectation for longer battery life, faster charging for their phones, electric vehicles (EVs) or power tools. And consumers want faster data communication along with powerful artificial intelligence (AI) capabilities,
Double doping could improve the light-harvesting efficiency of flexible organic solar cells (left), the switching speed of electronic paper (center) and the power density of piezoelectric textiles (right). Disclaimer: The image may only be used with referral to Epishine, as supplier of the flexible solar cell. For instance: 'The solar cell was supplied by Epishine AB.'
Researchers from Chalmers University of Technology, Sweden, have discovered a simple new tweak that could double the efficiency of organic electronics. OLED-displays, plastic-based solar cells and bioelectronics are just some of the technologies that could benefit from their new discovery, which deals with "double-doped"
All-optical switching. Data is stored in the form of 'bits', which contains digital 0 (North Poles down) or 1 (North Poles up). Data writing is achieved by 'switching' the direction of the poles via the application of short laser pulses (in red).
Light is the most energy-efficient way of moving information. Yet, light shows one big limitation: it is difficult to store. As a matter of fact, data centers rely primarily on magnetic hard drives. However, in these hard drives, information is transferred at an energy cost that is nowadays exploding. Researchers
MIDDLEBOROUGH, Mass. – Sager Electronics is now stocking RRC’s FlatPAQ lithium-ion smart battery pack.
The new RRC2130 battery with just 8mm in thickness is extremely thin. It is designed to fit into very slim devices, such as the back of a PC display or on a PC board, to allow developers to make
Novel colloidal quantum dots are formed of an emitting cadmium/selenium (Cd/Se) core enclosed into a compositionally graded CdxZn1-xSe shell wherein the fraction of zinc versus cadmium increases towards the dot's periphery. Due to a directionally asymmetric lattice mismatch between CdSe and ZnSe, the core, at top right, is compressed more strongly perpendicular to the crystal axis than along it. This leads to modifications of the electronic structure of the CdSe core, which beneficially affects its light-emission properties. Bottom image: Experimental traces of emission intensity from a conventional quantum dot (upper panel) and a novel asymmetrically compressed quantum dot (lower panel) resolved spectrally and temporally. The emission from the conventional quantum dot shows strong spectral fluctuations ("spectral jumps" and "spectral diffusion"). The emission from the asymmetrically compressed quantum dots is highly stable in both intensity and spectral domains. In addition, it shows a much narrower linewidth, which is below the room-temperature thermal energy (25 meV).
LOS ALAMOS, N.M.--Intentionally "squashing" colloidal quantum dots during chemical synthesis creates dots capable of stable, "blink-free" light emission that is fully comparable with the light produced by dots made with more complex processes. The squashed dots emit spectrally narrow light
They were the first to control exciton flows at room temperature. And now, the team of scientists from EPFL's Laboratory of Nanoscale Electronics and Structures (LANES) has taken their technology one step further. They have found a way to control some of the properties of excitons and change the polarization
