For centuries, ivory was often used to make art objects. But to protect elephant populations, the ivory trade was banned internationally in 1989. To restore ivory parts of old art objects, one must therefore resort to substitute materials - such as bones, shells or plastic. However, there has not been a really satisfactory solution so far.

Researchers have developed a method that uses machine learning, satellite imagery and weather data to autonomously find hotspots of heavy air pollution, city block by city block.

The Morrison and Marshall Governments have signed a $1.08 billion State Energy and Emissions Reduction Deal that will deliver secure, reliable and affordable energy to South Australians and help Australia continue to meet and beat its emissions reduction targets.

Gas accidents such as toxic gas leakage in factories, carbon monoxide leakage of boilers, or toxic gas suffocation during manhole cleaning continue to claim lives and cause injuries. Developing a sensor that can quickly detect toxic gases or biochemicals is still an important issue in public health, environmental monitoring, and military sectors.

Silicon solar cells have been steadily improved over the past decades and have already reached a very high level of development. However, the disturbing effect of recombination still occurs after the absorption of sunlight and the photovoltaic generation of electrical charge carriers. In this process, negative and positive charge carriers that have already been generated combine and cancel each other out before they could be used for the flow of solar electricity. This effect can be countered by special materials that have a special property - passivation.

Bodycote, the world's largest provider of heat treatments and specialist thermal processing services, is targeting the marine renewables sector after securing work with wave energy pioneer CorPower Ocean.

Equinor is introducing autonomous ATEX-certified robots on their oil and gas installations. Its robot will be used to conduct routine inspection and maintenance tasks on offshore installations.

Current research on flexible electronics is paving the way for wireless sensors that can be worn on the body and collect a variety of medical data. But where do the data go? Without a similar flexible transmitting device, these sensors would require wired connections to transmit health data.

The combination of a 2-Photon 3D-printer with an innovative hydrogel-based bioink allows the direct printing of 3D structures containing living cells at both the meso- and microscale.

Aggreko has installed a new Combined Heat and Power solution at the CET Arad Power Plant, Romania. The solution will help to increase efficiency and stability at the plant, a key provider of hot water and electricity for the district heating scheme and grid at the regional capital Arad City, for the next four years.

Engineers have created a tiny wireless implant that can provide real-time measurements of tissue oxygen levels deep underneath the skin. The device, which is smaller than the average ladybug and powered by ultrasound waves, could help doctors monitor the health of transplanted organs or tissue and provide an early warning of potential transplant failure.

Graphene excels at removing contaminants from water, but it's not yet a commercially viable use of the wonder material. That could be changing.

With marine energy on the cusp of significant growth, the National Hydropower Association unveiled new industry deployment targets of 50 MW by 2025, 500 MW by 2030, and 1 GW by 2035.

Drones could soon be adopted as essential tools for various agricultural tasks; however, with respect to their use in farm management, research is still lacking. To address this issue, researchers in Japan compared drones to well-established technologies for spraying pesticide over rice paddy fields. Using statistical data, the researchers explore both advantages and limitations of drones and whether they currently offer an edge regarding costs, capacity, and management efficiency.

Strata Clean Energy LLC is announcing its new name, Strata Clean Energy. The rebrand represents the company's commitment to the proliferation of clean energy products by providing more safe and reliable renewable energy options - especially for large, utility scale energy consumers.

Increased electrification of transportation, including inland waterway transport, will play a key role in helping Portugal achieve carbon neutrality by 2050. According to the national 2050 Carbon Neutrality Roadmap, the transport sector aims to achieve 98 percent reduction in greenhouse gas emissions compared to 2005, by strengthening the role of the public transport system and replacing current fossil fuel means of transportation with a mainly electric fleet.
