Bearings play an important role in the proper functioning of mechanical systems; in other words, they allow machines to run smoothly and safely. The purpose of a bearing is to reduce friction between moving parts and restrict their motion to the...
NASA engineer introduces the helical engine that can take us to interstellar distances without refueling. With enough power and time, it would be able to attain 99% of the speed of light. The concept is quite bizarre but worth exploring. Deep...
Researchers developed a better version of alternating current electroluminescent displays. Since this stretchable display operates at low voltages, it can be safely stuck on human skin like a temporary tattoo. The increasing demand for smart...
Computers perform an extremely wide range of tasks by following generalized sets of operations, called programs. They are used as control systems for various consumers and industrial devices, including smartphones and factory devices such as...
New lithium-carbon dioxide batteries can be fully charged/recharged up to 500 consecutive charge/discharge cycles. The battery is made by integrating a unique combination of materials. Lithium-ion batteries are used in almost all consumer...
Vehicles that are used by the military either to engage in combat or transport personnel are distinguished as military vehicles. After the Second World War, new technologies were rigorously introduced to make these machines more efficient and...
Like many other technological devices, microscopes have a very long history. The earliest microscopes contained simple magnifying glass with low power (up to 10 times). They were used to observe small insects such as fleas. The early versions of...
Researchers demonstrate a 16-bit microprocessor consisting of over 14,000 carbon nanotubes. It is capable of running all formats and types of instruction in the RISC-V instruction-set architecture. The entire computer industry is currently based on...
The first full-scale, self-propelled car was built by Nicolas-Joseph Cugnot in 1769: it was a steam-powered tricycle. A variety of steam cars were then built during the first half of the 19th century. In 1886, a German engineer invented the first...
The new thermoelectric device can produce electricity at nighty by harnessing the dark, cold environment. In the initial proof of concept demonstration, it produced 25 milliwatts of energy per square meter, which is enough to power a small LED. ...
