Flexible large-area ultrasound arrays for medical applications made using embossed polymer structures.

With the huge progress in micro-electronics and artificial intelligence, the ultrasound probe has become the bottleneck in further adoption of ultrasound beyond the clinical setting (e.g. home and monitoring applications).

Uncorrelated dynamical processes in tetranuclear carboxylate clusters studied by variable-temperature 1H NMR spectroscopy.

Tetranuclear carboxylate clusters with the general structural formula [M4(L)2(O2CR)4] (M = Cd, Zn; LH2 = 2,6-bis(1-(2-hydroxyphenyl)-iminoethyl)pyridine; R = CH3, C6H5) were studied by variable-temperature (VT) (1)H NMR spectroscopy. The dynamics of these clusters in solution can be described by two uncorrelated dynamical processes. The first dynamical process is the interconversion, both inter- as well as intramolecular, between syn-syn bridging and chelating carboxylate ligands.
