Dive into the world of molecules
Brand new technology in the classroom: students immerse themselves in a "mixed reality" and use HoloLens glasses to learn a fundamental principle of proteins.
View ArticleFlexibility and arrangement—the interaction of ribonucleic acid and water
Ribonucleic acid (RNA) plays a key role in biochemical processes that occur at the cellular level in a water environment. Mechanisms and dynamics of the interaction between RNA and water were now...
View ArticleThe first precise measurement of a single molecule's effective charge
For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future...
View ArticleQuantum speed limit may put brakes on quantum computers
Over the past five decades, standard computer processors have gotten increasingly faster. In recent years, however, the limits to that technology have become clear: Chip components can only get so...
View ArticleIngredients for life revealed in meteorites that fell to Earth
Two wayward space rocks, which separately crashed to Earth in 1998 after circulating in our solar system's asteroid belt for billions of years, share something else in common: the ingredients for life....
View ArticleNew study visualizes motion of water molecules, promises new wave of...
A novel approach to studying the viscosity of water has revealed new insights about the behavior of water molecules and may open pathways for liquid-based electronics.
View ArticleTracking a solvation process step by step
Chemists of Ruhr-Universität Bochum have tracked with unprecedented spatial resolution how individual water molecules attach to an organic molecule. They used low-temperature scanning tunneling...
View ArticleAtoms rearrange in electrolyte and control ion flow under tough conditions
Minerals that make up rocks and soils are thrown out of equilibrium when the chemistry of their surroundings changes. Shifts in pH or the concentration of ions in water make minerals dissolve, grow, or...
View ArticleFirst mathematical network model for the Battle of the Sexes
Why is it easier to bridge conflicting interests in one neighbourhood than in another? Social scientists think that the residents' social networks may play an important role in the answer to this...
View ArticleScientists channel graphene to understand filtration and ion transport into...
Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms—ions—but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a...
View ArticleIce skating on water, even when it is really cold
The outermost layer of ice behaves like liquid water, even at a temperature of –30°C. Physicists at AMOLF have irrefutably demonstrated this using a modern surface-sensitive measuring technique. At...
View ArticleCooking fats in the atmosphere may affect climate more than previously thought
Fats being released into the atmosphere from cookers such as deep fat fryers may be enhancing the formation of clouds, which have a major cooling effect on the planet.
View ArticleIonic 'solar cell' could provide on-demand water desalination
Modern solar cells, which use energy from light to generate electrons and holes that are then transported out of semiconducting materials and into external circuits for human use, have existed in one...
View ArticleMiniature droplets could solve an origin-of-life riddle
It is one of the great ironies of biochemistry: life on Earth could not have begun without water; yet water stymies some chemical reactions necessary for life itself.
View ArticleCold molecules on collision course
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at the same time. Scientists around Dr. Martin...
View ArticleNew experiments and simulations reveal molecular interactions in extreme...
Water is everywhere. But it's not the same everywhere. When frozen under extreme pressures and temperatures, ice takes on a range of complex crystalline structures.
View ArticleStudying entropy in metallic glasses
A team led by Caltech recently solved a decades-old materials science mystery by tracking down the origin of entropy in metallic glasses.
View ArticleA new way to produce clean hydrogen fuel from water using sunlight
Osaka University-led researchers develop new metal-free photocatalyst and show visible and near infrared light-driven production of hydrogen from water.
View ArticleConfined within tiny carbon nanotubes, extremely cold water molecules line up...
Single-walled carbon nanotubes act like tiny straws that are so narrow that water confined within cannot freeze into its normal crystal-like structure. In particular, in very thin nanotubes, water...
View ArticleNew efficient catalyst for key step in artificial photosynthesis
Chemists at the U.S. Department of Energy's Brookhaven National Laboratory have designed a new catalyst that speeds up the rate of a key step in "artificial photosynthesis"—an effort to mimic how...
