In nanotechnology control is key. Control over the arrangements and distances between nanoparticles can allow tailored interaction strengths so that properties can be harnessed in devices such as plasmonic sensors. Now researchers use dendrimers that mimic the electron valency of atoms and link them into arrays using molecules that coordinate with the dendrimer as they would form a covalent electron pair in their valence shell - 'electron pair mimicry'.
Researchers have succeeded in measuring tiny changes in strong magnetic fields with unprecedented precision. The researchers were able to detect even the tiniest variations of the magnetic field strength within the droplet. These changes were up to a trillion times smaller than the seven tesla field strength of the MRI scanner used in the experiment.
For the first time, scientists observed critical magnetic susceptibility of an organic material with a triangular lattice, when the material was in a quantum spin-liquid state at very low temperatures.
Controlling the way fluorinated polymer chains twist and turn may enable fast and flexible electrical circuits. The findings may offer substantial impact on the development of new polymer-type materials used in flexible electronic applications.
Researchers have now introduced the first CVD method for producing degradable polymers. Biomolecules or drugs can be attached by means of special side groups. This introduces new possibilities for applications like the coating of biodegradable implants.
Scientists have found that molybdenum sulfide (MoS2) holds more promise than previously thought as a catalyst for producing hydrogen to use as a clean energy source. Specifically, they found that the entire surface of MoS2 can be used as a catalyst, not just the edges of the material.
