Enhanced photoelectrochemical water splitting with a donor-acceptor polyimide
Polyimide (PI) has emerged as a promising organic photocatalyst owing to its distinct advantages of high visible-light response, facile synthesis, molecularly tunable donor-acceptor structure, and excellent physicochemical stability. However, the syn.....»»
Small-scale study finds microplastics from natural fertilizers are blowing in the wind more often than once thought
Though natural fertilizers made from treated sewage sludge are used to reintroduce nutrients onto agricultural fields, they bring along microplastic pollutants too. And according to a small-scale study published in Environmental Science & Technology.....»»
Cancer-related mutations appear in stem cell derivatives used in regenerative medicine, shows study
Human pluripotent stem cells are cells that have two very important traits—a seemingly endless proliferative capability and the amazing ability to give rise to any cell in our body. These characteristics make these cells a great tool for research o.....»»
Research team develops anti-icing film that only requires sunlight
A KAIST research team has developed an anti-icing and de-icing film coating technology that can apply the photothermal effect of gold nanoparticles to industrial sites without the need for heating wires, periodic spray or oil coating of anti-freeze s.....»»
Obtaining hydrogen from vine shoots for biofuel production
A research team from the universities of Jaén and São Paulo in Brazil has confirmed that hydrogen can be obtained from vine shoots through a process that does not require fossil fuels and does not emit pollutants. With their work, they manage to gi.....»»
Study finds carbon released during macroalgal growth has significant sequestration potential
Macroalgae are the most productive plants in coastal ecosystems. They have attracted worldwide interest due to their ability to sequester carbon. The growth of macroalgae can produce significant amounts of particulate organic carbon (POC), but it is.....»»
Methane activation by [LnO]+: The 4f orbital matters
As the "holy grail" in the field of chemistry, the catalytic activation of methane has been a topic of great interest in the field of heterogeneous catalysis. Gas-phase experiments provide an ideal platform for exploring catalytic reaction mechanisms.....»»
The largest US dam-removal effort to date has begun
As US dams age, removal is always an option—and it can be done well. Enlarge / The John C. Boyle Dam, one of the dams slated for removal. (credit: NOAA) Wending its way from the Olympic Mountains to the Strait of Juan.....»»
Researchers report successful synthesis of specific chiral molecules using rearrangements of simple hydrocarbons
In nature, organic molecules are either left- or right-handed, but synthesizing molecules with a specific "handedness" in a lab is hard to do. Make a drug or enzyme with the wrong "handedness," and it just won't work. Now chemists at the University o.....»»
Study show dry-cleaning fluid holds promise for sustainable organic synthesis
The widely used dry-cleaning and degreasing solvent perc can be converted to useful chemicals by a new, clean, safe, and inexpensive procedure. The Kobe University discovery using on-demand UV activation may open the path to upcycling perc and thus c.....»»
Novel chemical recycling system for vinyl polymers of cyclic styrene derivatives
Chemical recycling of widely used vinyl polymers (VPs) is one of the key technologies required for realizing a sustainable society. In this regard, a team of researchers from Shinshu University have recently reported a new chemical process that facil.....»»
Perovskite LEDs, a thousand times brighter than OLEDs
Light-emitting diodes (LEDs) have revolutionized modern lighting and sensing technology. From applications in our homes to industry, LEDs are used for all lighting applications, from indoor lighting over TV screens to biomedicine. Widely used organic.....»»
Add-on system in Mars water mining operations will screen for introduced and alien life
As noted at NASA's 2019 Carlsbad Conference, we have good reason to think that life could have started on Mars using the same geo-organic chemistry that started life on Earth. If Martian life persists today on Mars, it may be in near-surface ice, low.....»»
Titan"s "magic islands" are likely to be honeycombed hydrocarbon icebergs, finds study
Titan's "magic islands" are likely floating chunks of porous, frozen organic solids, a new study finds, pivoting from previous work suggesting they were gas bubbles. The study was published in Geophysical Research Letters......»»
