Though different fabrication approaches exist, two-step deposition is one of the main experimental techniques now used to make efficient, stable PSCs, especially on the industrial scale. The process involves first depositing lead iodide (PbI2) and then adding halide salts of monovalent cations such as methylammonium iodide (MAI) and formamidinium iodide (FAI) to convert it to perovskite.

Simon Fraser University researchers have designed a remarkably fast engine that taps into a new kind of fuel—information.

In the recent years Tallinn University has paid a lot of attention to becoming agile in business collaboration, including both local and international EdTech companies. Their collaboration with the company TTS Group started last year, and the common interest is to develop and implement novel STEAM and educational robotics-related teaching practices for kindergartens and primary schools. The special interest lies in inclusive education and integrating technology with the subjects that are taught in Estonian educational institutions.

For the last time while it is on Earth, the world's largest and most powerful space science telescope opened its iconic primary mirror. This event marked a key milestone in preparing the observatory for launch later this year.

Extreme weather is harming UK agriculture—but many farmers have not yet made adapting to the effects of the climate emergency a priority, a new study shows.

The COVID-19 pandemic has presented a new world of challenges for education. But a new study from the University of Kansas shows the voices and experiences of students who are already among the most marginalized can help lead the way in making young people's strengths the focus of education.

This rare fossil find comes from the Kimmeridge Clay Formation in England, a series of sedimentary rocks that was formed in a shallow, tropical-subtropical sea during the Upper Jurassic, about 150 million years ago. The fossil shark skeleton was found more than 20 years ago on the southern coast of England and is now held in the Etches Collection. Additional fossil shark specimens from it will be investigated in the years to come.

Roads can be barriers to wildlife of all sorts, and scientists have studied road impacts on animals ranging from Florida panthers and grizzly bears to box turtles, mice, rattlesnakes and salamanders.

Controlling, and mitigating the effects of ice growth is crucial to protect infrastructure, help preserve frozen cells and to enhance texture of frozen foods. An international collaboration of Warwick scientists working with researchers from Switzerland have used a phage display platform to discover new, small, peptides which function like larger antifreeze proteins. This presents a route to new, easier to synthesize, cryoprotectants.Caption: Using viruses (phage display) to identify the one molecule... Читать дальше...

Tepary beans—a high protein legume common to the southwest United States and Mexico—may hold the key to adapting bean crops for the increasingly harsh conditions brought on by a changing climate, according to research led by University of Saskatchewan (USask) and Michigan State University.

Northern Chile is an ideal natural laboratory to study the origin of earthquakes. Here, the Pacific Nazca plate slides underneath the South American continental plate with a speed of about 65 millimeters per year. This process, known as subduction, creates strain between the two plates and scientists thus expected a mega-earthquake here sooner or later, like the last one in 1877. But although northern Chile is one of the focal points of global earthquake research, until now there was no comprehensive... Читать дальше...

A reliable projection of extreme El Niño frequency change in a future warmer climate is critical to managing socio-economic activities and human health, strategic policy decisions, environmental and ecosystem managements, and disaster mitigations in many parts of the world. Unfortunately, long-standing common biases in CMIP5 models, despite enormous efforts on the numerical model development over the past decades, make it hard to achieve a reliable projection of the extreme El Niño frequency change in the future.

A team of researchers at Federation University in Australia has found that there is no connection between the relationship boys have with their father as they grow up and their adherence to masculine norms later on in life. In their paper published in the journal Personality and Individual Differences the group describes developing a questionnaire aimed at assessing views on masculinity and the type of relationship a person had with their father and administering it to male volunteers.

Astronomers have performed high-resolution observations of a complex planetary nebula known as NGC 1514. Results of the study provide essential information about morpho-kinematical structure and chemical composition of this nebula, which could help researchers to better understand its nature. The research was published May 4 on arXiv.org.

A ceremonial tsantsa—or shrunken head—was authenticated and repatriated to Ecuador in 2019, after it had been discovered amongst stored exhibits at Mercer University. The history of the artefact and the process of its authentication—which involved CT scans and assessment of 33 criteria such skin and hair features—are described in a study published in Heritage Science.

According to the International Whaling Commission, whale-watching tourism generates more than $2.5 billion a year. After the COVID-19 pandemic, this relatively safe outdoor activity is expected to rebound. Two new studies funded by a collaborative initiative between the Smithsonian Tropical Research Institute (STRI) in Panama and Arizona State University (ASU) show how science can contribute to whale watching practices that ensure the conservation and safety of whales and dolphins.

Scientists have figured out what triggers large-scale volcanic eruptions and what conditions likely lead to them.
