Thomas Alva Edison took all the credit in 1879, but the invention originated a long time before that. Seventy years earlier, Humphry Davy, originally from Cornwall in the United Kingdom, had managed to fix a thin strip of carbon between the two poles of a battery. Thus was born the first lightbulb: an invention that […]

Peru’s gold exports to India are set to jump 36% from a year ago to a record $3 billion in 2024, driven by rising demand from the world’s second-biggest consumer, a senior government official said on Friday. India’s gold imports from Peru in the first half of 2024 rose 81% from a year ago to […]

Your early morning run could soon help harvest enough electricity to power your wearable devices, thanks to a new nanotechnology developed at the University of Surrey. Surrey’s Advanced Technology Institute (ATI) has developed highly energy-efficient, flexible nanogenerators, which demonstrate a 140-fold increase in power density when compared to conventional nanogenerators. ATI researchers believe that this […]

A big facility for recycling lithium-ion batteries is now operating in Central Ohio, where workers are busy salvaging and repurposing the metals and minerals needed to drive the clean energy transition. On Thursday, Cirba Solutions officially opened its expanded battery recycling plant in Lancaster — making it the first project of any kind to come […]

In an effort to reduce the environmental impact of carbon dioxide emissions, a University of Central Florida researcher has developed a new technology that captures carbon dioxide and outputs useful fuels and chemicals. Yang Yang, an associate professor in UCF’s NanoScience Technology Center, created an innovative device that captures carbon dioxide with a microsurface comprised […]

An eco-friendly technology inspired by plant and animal mechanisms has been developed in South Korea for the first time. The portable moisture-harvesting system collects moisture from the air, purifies it, and produces drinkable water. This innovative system is expected to have wide-ranging applications, including in military operations, camping, and survival water production in remote and […]

Over the past few decades, electronics engineers have developed increasingly flexible, versatile and highly performing devices for a wide range of real-world applications. Some of their efforts have been aimed at creating smart and sensing textiles, which could be used to fabricate stretchy robotic systems, medical devices and wearable technologies. Researchers at Jiangnan University recently […]

Porsche’s decision to support Varta will allow the luxury car maker to have access to high-performance batteries for its hybrid and electric cars. Struggling firm Varta has reached an agreement with creditors to secure fresh capital and alleviate its debt, notably by accepting the support of car manufacturer Porsche. According to new proposals, Porsche will […]

Air quality has become one of the most important public health issues in Africa. Poor air quality kills more people globally every year than HIV, TB and malaria combined. And that’s just the tip of the iceberg. Air pollution makes people less productive because they get headaches and feel tired. India, for example, has poor […]

Hydrogen is a fuel alternative that is becoming increasingly interesting for heavy-duty vehicles. Hydrogen-powered vehicles only emit water vapor as exhaust, and if the hydrogen is produced using renewable energy, it is completely free of carbon dioxide emissions. Unlike battery-powered electric vehicles, hydrogen-powered vehicles do not need to burden the electricity grid, as hydrogen can […]
