Analytical method for risk assessment of products and food
Scientists from the Universities of Dresden and Leipzig have presented a new method for detecting hormonally active substances in food, cosmetics and water in the journal “Biosensors & Bioelectronics”. Hormonally active substances can cause serious health problems, including breast and prostate ...
Are targeted attacks possible?
Highly reactive molecules cannot survive for long in nature. If researchers want to study them more closely, they therefore have to be produced under very specific laboratory conditions. Compared to “normal” molecules, many of these tiny particles have a distinguishing feature: they simply bind ...
“We Marry Disorder with Order”
We’ve all come across them before: those little bags of small balls that come packed together with new shoes or electrical goods. The balls are there to absorb moisture so as to protect the items from damage. “These materials act like a sponge,” explains physicist Professor Rustem Valiullin from ...
Recent developments in atomic-force microscopy have enabled researchers to apply mechanical forces to individual molecules to induce chemical reactions. A research team from Spain and Germany has now developed a first-of-its-kind algorithm that determines the minimal force it takes to reach the ...
New discoveries about spider silk could inspire novel materials to manipulate sound and heat in the same way semiconducting circuits manipulate electrons, according to scientists at Rice University, in Europe and in Singapore. A paper looks at the microscopic structure of spider silk and reveals ...
Scientists from the Vrije Universiteit Brussel and the Universität Leipzig have discovered a unique behavior in the transport of molecules in nanoporous materials. They disproved the validity of a decades-old unquestioned assumption and demonstrated that each individual nanoporous crystal behaves ...
Nano-sized faucet offers experimental support for longstanding quantum theory
We all know intuitively that normal liquids flow more quickly as the channel containing them tightens. Think of a river flowing through narrow rapids. But what if a pipe were so amazingly tiny that only a few atoms of superfluid helium could squeeze through its opening at once? According to a ...
"Please buckle up. We are flying through an area with strong turbulence.” Some passengers might be petrified by such an announcement, but the atmosphere and climate researchers from Germany, Brazil and Israel were delighted last month to hear these words. Within the framework of a large-scale ...
A new theory for the breaking of (bio-)chemical bonds under load may help to predict the strength and performance of synthetic nanostructures and proteins, on a molecular level. The fundamental question how a molecular bond breaks is of interest in many fields of science and has been studied ...
"Metallic" odor of iron, iron-containing water, and blood derives from the decomposition of skin oil
Where does the strange but typical "metallic" smell come from when we touch iron objects such as tools, utensils, railings, or coins? "The smell of iron upon contact with skin is ironically a type of human body odor," states Dietmar Glindemann. "That we are smelling the metal itself is actually ...
