The World Meteorological Organization’s State of the Climate in Asia 2024 report warns that the region is warming nearly twice as fast as the global average, driving more extreme weather and posing serious threats to lives, ecosystems, and economies. In 2024, Asia experienced its warmest or second warmest year on …
heavy ion accelerators are usually thought of as poor country cousins of the big particle accelerators. While particle accelerators explore the realm of the smallest distances known, the ion machines are used for understanding the behaviour of atoms and discovering new elements. But now, Germany's heavy ion laboratory, the gsi …
one of the most remarkable advances in material science has been the development and study of thin metallic films. These are made by evaporation of metals onto a substrate in highly controlled conditions. The unique properties of these films
Driven by the demands of the aerospace and semi-conductor industrial materials, scientists have developed many advanced technologies to coat and modify metal surfaces. Plasma spraying and ion implantation are two such technologies that, in certain applications, can outperform more established methods of improving metal surfaces. Ion implantation can extend the …
a prototype aircraft that flies by itself at five times the speed of sound has recently been unveiled in the us . Its futuristic shape has led to the speculation that a secret full-size version of the plane could be responsible for ufo (unidentified flying object) sightings. The wedge-shaped LoFlyte's …
researchers in the us have shown that a technology called extreme ultraviolet light ( euv ) lithography may illuminate the path to the next generation of semiconductor chips. Chips manufactured with euv technology are likely to be 10 times faster than today's chips and will be able to store 1,000 …
The Eurofighter (EF)-2000, being developed for the air forces of the UK, Germany, Italy and Spain, will be the first aircraft to have an integrated structural health and usage system developed by the British Aerospace (BA). The system performs real-time fatigue calculations and determines the life consumed by the airframe. …
the world's first anti-gravity device which could have an immense effect on everything from transport to power generation has been developed by researchers at the Tampere University of Technology in Finland. The device is said to significantly reduce the weight of any object placed above it. Such has been the …
A Japanese construction firm, Taisei Corporation, has developed a soil bioremediation technique that offers a less expensive and environmentally benign response to soil that has been contaminated by oil. The new technique employs bacteria that can breakdown hydrocarbon molecules into small innocuous compounds. Certain strains of soil-dwelling bacteria naturally degrade …
winter ice, which severely disrupts shipping in colder climes, may no longer pose a problem. A Canadian marine engineer, Per Andersen, claims that he has found a technique to control ice formation. His wave generator projector could prevent sea water from freezing, by producing artificial waves ( New Scientist , …
Electron crystallography, although catching up fast, has a disadvantage: there is a strong interaction between the electrons of the probe and the sample itself. Now, T E Weirich and his colleagues have obtained the complete determination of an unknown structure for the compound Ti_11 Se_4 by electron crystallography. This is …
Nikon recently unveiled the first digital camera in Japan that adds spoken and hand-written captions to photographs. The new camera, about the size of a mobile phone, has a microphone for recording live commentary. Up to 17 minutes of audio information can be stored in it. The sound clips can …
by the year 2020, factories far smaller than the head of a pin will manufacture everything from microwave ovens to sophisticated pistons. According to an American futurist, K Eric Drexler, the future belongs to the science of molecular design called nanotechnology ( Scientific American , Vol 274, No 4). Nanotechnology …
already the world's masters of miniaturisation, Japanese companies are set to challenge their competitors with insect-sized machines having parts as small as specks of dust. A demonstration of Japanese micro-machine technology is the
it will be a test of technology and human endurance . T wo British cyclists will appear at the air show at Farnborough, uk , this month in an attempt to set a world speed record on a tandem built from stealth-fighter materials. They believe their bike is capable of …
nanometre-sized molecular materials hold great promise for future generation devices. These materials could serve as building blocks of electronic devices of an amazingly small size or could even form the basis for self-assembling machines. But before all that, it is essential to understand the fundamental electrical and mechanical properties of …
at all costs: The Mathura refinery seems to be sparing no cost for sprucing up its image on the green front. It has invested Rs 18,620 million to minimise polluting emissions. For this purpose, it is going to install a catalytic reforming unit at a cost of Rs 5,450 million, …
