A new laser oscillator generates ultrashort pulses, 50% more powerful than the previous record.

Researchers at ETH Zurich have developed a laser oscillator that produces the most powerful ultra-short laser pulses ever.

The pulses from the laser last for less than 10⁻¹² seconds. However, on average, they carry 550 watts of power, with peak power output reaching 100 megawatts — this is more than enough to power hundreds of thousands of vacuum cleaners together for a short duration.

“They surpass the previous maximum by more than 50 percent. This is, to the best of our knowledge, the highest average power and highest pulse energy ever achieved for any modelocked oscillator,” the researchers note.

Researchers have succeeded in developing a framework for organic thermoelectric power generation from ambient temperature and without a temperature gradient. Thermoelectric devices are devices that can convert heat into electrical energy. Researchers have now developed a thermoelectric device composed of organic materials that can generate electricity from ambient temperature alone. The device is made from copper phthalocyanine and copper hexadecafluoro phthalocyanine as charge $transfer materials and was combined with fullerenes and BCP as electron transport layers.

Researchers have developed a new organic thermoelectric device that can harvest energy from ambient temperature. While thermoelectric devices have several uses today, hurdles still exist to their full utilization. By combining the unique abilities of organic materials, the team succeeded in developing a framework for thermoelectric power generation at room temperature without any temperature gradient. Their findings were published in the journal Nature Communications.

Thermoelectric devices, or thermoelectric generators, are a series of energy-generating materials that can convert heat into electricity so long as there is a temperature gradient — where one side of the device is hot and the other side is cool. Such devices have been a significant focus of research and development for their potential utility in harvesting waste heat from other energy-generating methods.

A new study introduces an eco-friendly method using an AEM electrolyzer to hydrogenate cyclic amines, reducing the chemical industry’s carbon emissions. This process replaces fossil fuels with water and renewable electricity, maintaining high efficiency.

To reduce the environmental impact of the chemical manufacturing industry, it is crucial to develop greener methods for producing the chemical building blocks of widely used compounds.

It’s no secret manufacturing processes have some of the most impactful and intense effects on the environment, with the chemical manufacturing industry topping the charts for both energy consumption and emissions output. While this makes sense thanks to the grand scale in which manufactured chemicals are involved in daily life, it still leaves a lot to be desired for sustainability’s sake. By focusing on renewable energy sources and alternative methods for creating the chemical building blocks of some of the most commonly used compounds, researchers hope to reduce the chemical manufacturing industry’s footprint with some green innovation.

“Our microwave induction heating technology enables fast and easy preparation of hard carbon, which I believe will contribute to the commercialization of sodium-ion batteries,” said Dr. Daeho Kim.

Can sodium-ion batteries be improved to exceed the efficiency and longevity of traditional lithium-ion batteries? This is what a recent study published in Chemical Engineering Journal hopes to address as a team of researchers from South Korea investigated how microwave induction heating can produce sufficient carbon anodes used in sodium-ion batteries. This study holds the potential to help researchers and engineers better understand how to develop and produce efficient sodium-ion batteries, which have demonstrated greater abundancy and stability.

“Due to recent electric vehicle fires, there has been growing interest in sodium-ion batteries that are safer and function well in colder conditions. However, the carbonization process for anodes has been a significant disadvantage in terms of energy efficiency and cost,” said Dr. Jong Hwan Park, who is from the Korea Electrotechnology Research Institute (KERI) and a co-author on the study.

For the study, the KERI-led researchers improved upon existing sodium-ion batteries by using microwave technology, which involves heating carbon nanotubes using a microwave magnetic field, resulting in temperature exceeding 1,400 degrees Celsius (2,550 degrees Fahrenheit) in only 30 seconds. This breakthrough improves upon traditional methods for procuring carbon anodes, which typically require lengthy amounts of time to reach just 1,000 degrees Celsius (1,800 degrees Fahrenheit).

A novel type of superconductor that can operate at elevated temperatures has been found by scientists after nearly three decades of research.
