Engineering
Solar cells, devices that can directly convert radiation emitted from the sun into electricity, have become increasingly widespread and are contributing to the reduction of greenhouse gas emissions worldwide. While existing ...
Robotics
A talented teenager from the UK has built a four-fingered robotic hand from standard Lego parts that performs almost as well as research-grade robotic hands. The anthropomorphic device can grasp, move and hold objects with ...
Engineering
While most solar cells on the market today are based on silicon, energy engineers have recently been assessing the performance of alternative cells based on other photovoltaic (PV) materials. These alternative options include ...
Hardware
Over the past decades, electronics engineers have developed a wide range of memory devices that can safely and efficiently store increasing amounts of data. However, the different types of devices developed to date come with ...
Engineering
Conventional lithium-ion batteries are known to present a fire risk, and can even cause explosions in certain cases. The widespread usage of lithium-ion batteries, in everything from electric vehicles to electric toothbrushes, ...
Engineering
As electronic devices become increasingly powerful and compact, they can generate denser heat fluxes, or in other words, produce more heat in a smaller area. These heat fluxes raise the temperature of a device and can damage ...
Hi Tech & Innovation
Over the past decade, deep learning has transformed how artificial intelligence (AI) agents perceive and act in digital environments, allowing them to master board games, control simulated robots and reliably tackle various ...
Engineering
In recent years, energy engineers have been trying to design new reliable batteries that can store more energy and allow electronics to operate for longer periods of time before they need to be charged. Some of the most promising ...
Electronics & Semiconductors
Carbon nanotubes (CNTs), cylindrical nanostructures made of carbon atoms arranged in a hexagonal lattice, have proved to be promising for the fabrication of various electronic devices. In fact, these structures exhibit outstanding ...
Machine learning & AI
Like humans, artificial intelligence learns by trial and error, but traditionally, it requires humans to set the ball rolling by designing the algorithms and rules that govern the learning process. However, as AI technology ...
