A team of scientists from the Department of Energy’s Ames National Laboratory has developed a new characterization tool that allowed them to gain unique insight into a possible alternative material for solar cells. Under the leadership of Jigang Wang, senior scientist from Ames Lab, the team developed a microscope that uses terahertz waves to collect data on material samples. The team then used their microscope to explore methylammonium lead iodide (MAPbI₃) perovskite, a material that could potentially replace silicon in solar cells.

Richard Kim, a scientist from Ames Lab, explained the two features that make the new scanning probe microscope unique. First, the microscope uses the terahertz range of electromagnetic frequencies to collect data on materials. This range is far below the visible light spectrum, falling between the infrared and microwave frequencies. Secondly, the terahertz light is shined through a sharp metallic tip that enhances the microscope’s capabilities toward nanometer length scales.

“Normally if you have a light wave, you cannot see things smaller than the wavelength of the light you’re using. And for this terahertz light, the wavelength is about a millimeter, so it’s quite large,” explained Kim. “But here we used this sharp metallic tip with an apex that is sharpened to a 20-nanometer radius curvature, and this acts as our antenna to see things smaller than the wavelength that we were using.”

Genetic diversity enables coral species to adapt to threats from climate change, so researchers have designed an aquarium coral “family tree” to help maintain and promote genetic diversity.

It is the first coal carrier to be powered by hard sail wind power propulsion technology.

The world’s first partly wind-powered bulk carrier ship sailed to the Port of Newcastle on its maiden voyage this week.

The Japanese shipping company Mitsui O.S.K. Lines (MOL), which delivered the 100,422 dwt (dead-weight tonnage) bulker on October 7, 2022, sailed to Newcastle on Monday, reported *Offshore Energy*.

But do they really have the necessary skillset?The new CEO of Twitter, Elon Musk, has authorized 50 employees from his other companies, such as Tesla, SpaceX, and the Boring Company, to help him handle matters at the social media company, according to a report by CNBC.

Musk has billed himself as a free speech absolutist, but he has to balance those wishes with laws and business realities. He said in an open letter to advertisers last week as he was taking over the company: “Twitter obviously cannot become a free-for-all hellscape, where anything can be said with no consequences.”

It is not immediately clear how Tesla employees are expected to split their schedules between the automaker and Twitter.

The stadiums include a quiet room for those with cognitive disabilities. The FIFA World Cup to be held in Qatar this year is leading the way in accessibility for specially-abled people, according to a report by Euronews published on Wednesday. The event is making sure all can enjoy it.

Qatar unveiled a massive 40,000-seat arena for the World Cup that’s entirely crafted from shipping containers.

Built with the notion of sustainable construction in mind, Qatar officials are partnering with architects Fenwick Iribarren, Schlaich Bergermann Partner and Hilson Moran on the Ras Abu Aboud Stadium. The building could even earn a four-star rating from the Global Sustainability Assessment System (GSAS) certification.

There might be room for everyone, or not. At first glance, the connections between the world’s growing population and climate change seem obvious. The more people we have on this planet, the larger their collective impact on the climate.

The global population is projected to reach 8 billion on 15 November 2022, and India is projected to surpass China as the world’s most populous country in 2023, according to World Population Prospects 2022, released today on World Population Day.

“This year’s World Population Day falls during a milestone year, when we anticipate the birth of the Earth’s eight billionth inhabitant. This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates,” said UN Secretary-General António Guterres. “At the same time, it is a reminder of our shared responsibility to care for our planet and a moment to reflect on where we still fall short of our commitments to one another,” he added.
