Gas and liquid separation processes in the chemical industry could be made more efficient and environmentally friendly by using substances known as intrinsically porous materials (IPMs). KAUST researchers review the prospects for IPMs in the journal Accounts of Chemical Research.
Niveen Khashab and her team are currently heavily involved in IPM research. "We focus on making materials that will have an impact on the chemical and petrochemical industries in Saudi Arabia and the world," says Niveen Khashab, the corresponding author of the review.
Researchers have demonstrated that a slimy, yet tough, type of biofilm that certain bacteria make for protection and to help them move around can also be used to separate water and oil. The material may be useful for applications such as cleaning contaminated waters.
In the journal Langmuir, North Carolina State University researchers reported the findings of an experiment in which they used a material produced by the bacteria Gluconacetobacter hansenii as a filter to separate water from an oil mixture.
Scientists have used modern genetic techniques to prove age-old assumptions about what sizes of fish to leave in the sea to preserve the future of local fisheries.
"We've known for decades that bigger fish produce exponentially more eggs," said the lead author of the new study, Charles Lavin, who is a research fellow from James Cook University (JCU) and Nord University in Norway.
"However, we also found while these big fish contributed significantly to keeping the population going--they are also rare."
Polymer scientists from the University of Groningen and NHL Stenden University of Applied Sciences, both in the Netherlands, have developed a polymer membrane from biobased malic acid. It is a superamphiphilic vitrimer epoxy resin membrane that can be used to separate water and oil. This membrane is fully recyclable. When the pores are blocked by foulants, it can be depolymerized, cleaned and subsequently pressed into a new membrane. A paper describing the creation of this membrane was published in the journal Advanced Materials on 7 March 2021.
Non-Small Cell Lung Cancer (NSCLC) is the most prevalent form of lung cancer, accounting for more than 80 percent of all lung cancer cases. Despite the aggressive nature of NSCLC, circulating tumor cells that lead to metastases often go undetected in the blood compared to breast, prostate, colorectal, and other cancers.
Smoke from local wildfires can affect the health of Colorado residents, in addition to smoke from fires in forests as far away as California and the Pacific Northwest.
Researchers at Colorado State University, curious about the health effects from smoke from large wildfires across the Western United States, analyzed six years of hospitalization data and death records for the cities along the Front Range, which reaches deep into central Colorado from southern Wyoming.
Some of Princeton's leading cancer researchers were startled to discover that what they thought was a straightforward investigation into how cancer spreads through the body -- metastasis -- turned up evidence of liquid-liquid phase separations: the new field of biology research that investigates how liquid blobs of living materials merge into each other, similar to the movements seen in a lava lamp or in
Farmers in the Midwest may be able to bypass the warming climate not by getting more water for their crops, but instead by adapting to climate change through soil management says a new study from Michigan State University.
"The Midwest supplies 30% of the world's corn and soybeans," said Bruno Basso, an ecosystems scientist and MSU Foundation Professor in the Department of Earth and Environmental Sciences within the College of Natural Science. "These crops are sensitive to temperature and water changes."
New evidence published today in the Cochrane Library suggests that smokers who quit can feel the positive benefits within weeks.
The mountain forests of Tanzania are more than 9,300 miles away from Salt Lake City, Utah. But, as in eastern Africa, the wild places of Utah depend on a diversity of birds to spread seeds, eat pests and clean up carrion. Birds keep ecosystems healthy. So if birds in Tanzania are in trouble in a warming climate, as found in a recent study by University of Utah researchers, people in Utah as well as in the African tropics should pay attention.
Malaria is the deadliest pathogen in human history. Nearly half the people on Earth are at risk of contracting the disease from the parasites that cause it. But humans aren't the only ones who can get these parasites--different forms are found in other animals, including birds. By studying the DNA of those strains, scientists can get a better picture of how malarial parasites live, which may give clues on how to stop the disease.
Professor Rosalind Gill, from City, University of London's Gender and Sexualities Research Centre, has today published a new report to mark International Women's Day.
The report - Changing the Perfect Picture: Smartphones, Social Media and Appearance Pressures - is based on research with 175 young women and nonbinary people in the UK.
Recently, research group, led by Prof. FU Yao and associate research fellow LU Xi From Hefei National Laboratory for Physical Sciences at the Microscale and School of Chemistry and Materials Science of the University of Science and Technology of China (USTC), has made significant achievements in the field of synthesis of chiral amines. They developed a mild and general nickel-catalysed asymmetric reductive hydroalkylation and realized the modular synthesis of chiral aliphatic amines.
Results were published in Nature Communications on Feb. 26, 2021.
Along the western edge of Alaska's Aleutian archipelago, a group of islands that were inadvertently populated with rodents came to earn the ignominious label of the "Rat Islands." The non-native invaders were accidentally introduced to these islands, and others throughout the Aleutian chain, through shipwrecks dating back to the 1700s and World War II occupation.
The earliest multicellular organisms may have lacked heads, legs, or arms, but pieces of them remain inside of us today, new research shows.
According to a UC Riverside study, 555-million-year-old oceanic creatures from the Ediacaran period share genes with today's animals, including humans.
