Microscale energy storage units for wearable and miniaturized electronic devices are improved using porous materials.
The addition of a few nanometers of a thin layer of aluminum oxide protects a perovskite solar cell against humidity -- still a major stumbling block to the commercial application of this new type of solar cell. A surprising bonus is a yield boost of 3 percent. These are the findings of researchers at Eindhoven University of Technology (TU/e) and research institute ECN, part of the Solliance collective, published today in the journal Energy and Environmental Science.
Based on simulations, friction properties of the two-dimensional carbon graphene were studied by scientists of Karlsruhe Institute of Technology (KIT) and the Fraunhofer Institute for Mechanics of Materials IWM with scientists in China and the USA. In contact with monolayer graphene, friction is higher than with multi-layered graphene or graphite; friction force increases for continued sliding. The scientists attribute this to the real contact area and the evolving quality of frictional contact.
A collection of 780,000-year-old edible plants found in Israel reveals the plant-based diet of the prehistoric man and is the largest and most diverse in the Levantine corridor linking Africa and Eurasia.
The development of antibiotics generated a revolution in the way we look and treat bacterial infections. In spite of the initial success, new problems came along and raised allergic reactions, bacterial resistance and ecological problems. These consequences have encouraged the research of alternative solutions based on sustainable sources.
Tokyo Tech researchers show dendrimers that mimic the electron valency of atoms can also mimic polymerisation yielding controlled one and two-dimensional arrays of nanocontainers.
IBS and KAIST researchers clarify how laser annealing technology can lead to production of ultrathin nanomaterials.
The impassable blood-brain barrier prevents microorganisms from entering our brain, however it also blocks medicines that could help treat Parkinson's, Alzheimer's and other neurodegenerative diseases. Now, a Spanish physicist and other researchers at the University of Columbia (USA) have succeeded in embedding these substances in tiny lipid bubbles, in such a way that ultrasound can be used to release them into the specific area of the brain where they are needed.
Researchers at the University of Surrey have achieved record power conversion efficiencies for large area organic solar cells. In recent years scientists have been attempting to increase the efficiency of these cells to allow commercial applications such as integration into a building's glass façade, generating electricity to power the building.
Researchers from Brown University have shown a way to break superconductivity by disrupting the coherence of superconducting Cooper pairs. Such a phase change from superconducting to insulating had been predicted by theory, but hadn't been demonstrated experimentally. The research could help scientists better understand how defects can affect the quantum behavior of materials.
