The work, published in the Pertanika Journal of Science and Technology, suggests which factors should be taken into account before drilling for industrial and residential water supplies, as groundwater becomes a more important resource worldwide.
Groundwater has been used for centuries, but its usage is still limited to shallow, unconfined aquifers using hand-dug wells, or deeper wells on coarse sand aquifers. With much of the country’s industry based on hard rock, Nasiman Sapari and colleagues from the Universiti Teknologi PETRONAS analysed data from 136 industrial tube well drillings into hard rock.They found that these wells could yield up to 890 cubic metres per well per day – though the average was 343 cubic metres. 103 of the tube wells were productive, and the data show that those that penetrate weathered granite were generally non productive so these conditions can be avoided in future. Their analysis of the quality shows it is generally fresh water, with only 9% producing water harder than recommended for drinking. 42% had iron levels lower than the WHO standard.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
