Proper power grounding systems are crucial for maintaining the safety and reliability of critical electrical subsystem infrastructure, such as substations. These systems provide a low-resistance path for electrical fault currents to flow into the earth, ultimately preventing electrical shocks, fires, and damage to essential equipment. Soil resistivity plays a significant role in the design of

In a groundbreaking study led by Prof. Ye Hong and his research team at the University of Science and Technology of China, a novel alumina ceramic bionic wick has been developed for cooling high-performance electronic chips. Drawing inspiration from the stomatal array found in natural leaves, the researchers aimed to address the challenges posed by
In a landmark case involving Apple and Ireland, the 13-billion-euro tax dispute has reached a pivotal moment with an upcoming ruling by a top EU court. The conflict dates back to 2016 when the European Commission alleged that Ireland provided Apple with preferential tax treatment, allowing the tech giant to avoid paying billions in taxes.
Swedish electric car battery maker Northvolt recently announced that it would be reducing its workforce as part of scaling back operations to focus on its main gigafactory in Sweden. This decision comes at a time when the sales of electric cars are declining in Europe, and the region is significantly behind China in battery production.
The relationship between traditional journalism and big tech companies has evolved significantly over the years. While tech giants like Google and Facebook have revolutionized the way news is distributed and consumed, the question of press independence has become increasingly concerning. The financial and technical support provided by these companies through initiatives like the Google News
Apple’s iPhone has been a game-changer since its initial release in 2007, with the promise of reshaping society. Over the years, Apple has sold billions of iPhones, creating trillions in shareholder wealth. However, in recent years, there have been minor upgrades from one model to the next, causing a decline in sales. The unveiling of
In a recent move, the Australian government has introduced voluntary artificial intelligence (AI) safety standards in conjunction with a proposal to increase regulation on the utilization of this rapidly advancing technology in high-risk scenarios. The underlying plea from federal Minister for Industry and Science, Ed Husic, echoed the sentiment that more individuals need to embrace
The field of electronic components is constantly evolving, with researchers always on the lookout for materials that could revolutionize the industry. Two-dimensional (2D) semiconducting materials have emerged as promising candidates due to their unique optoelectronic properties. However, effectively integrating these materials with gate dielectrics has posed a challenge, leading to degraded transistor performance. Recently, researchers
As the United States continues its push towards greater home electrification in an effort to combat climate change, the focus has shifted towards heat pumps. Unlike the more popular electric cars or solar panels, heat pumps are often viewed as less glamorous but equally effective in reducing carbon emissions. These energy-efficient systems serve as both
Europe’s aviation safety agency recently announced the mandatory inspection of a portion of the Airbus A350 fleet in response to an engine fire on a Cathay Pacific flight. This incident has raised safety concerns and prompted action from both regulatory authorities and airlines involved. Rolls-Royce, the manufacturer of the engines on Cathay’s A350s, confirmed the
In a world where technology is advancing at an unprecedented rate, the interaction between humans and robots is becoming increasingly common. As robots take on more roles in society, the question of whether they should be allowed to deceive humans is a complex ethical dilemma that is being explored by researchers. A recent study conducted
Cathay Pacific recently faced a significant challenge when it had to ground 48 of its Airbus A350 planes for checks due to defective engine fuel lines. This issue led to the cancellation of dozens of flights, causing disruptions for passengers and impacting the airline’s operations. However, the airline has stated that it will resume full
As the former CEO of Volkswagen, Martin Winterkorn is scheduled to face trial this week for his involvement in the notorious “dieselgate” scandal. This scandal rocked the German auto industry in 2015 when it was revealed that VW had been using software to manipulate emissions levels in millions of vehicles worldwide. Winterkorn, who resigned from
Connecting wind turbines to the public power grid poses significant challenges for manufacturers. It is not just about testing the functionality of the turbines but also ensuring they comply with the electrical properties’ limit values specified in the connection rules. Moreover, dynamic events such as short circuits and frequency fluctuations need to be accounted for.
The COOLBat joint research project is paving the way for a new era in electric vehicles with its focus on developing next-generation battery enclosures. The primary goal of the project is to create lighter enclosures while reducing the carbon dioxide emitted during the manufacturing process by 15%. By combining innovative lightweight construction principles, advanced materials,
