Publications by authors named "Padraig Murphy"

Background: Scientific publications have been growing exponentially, contributing to an oversaturated information environment. Quantifying a research output's impact and reach cannot be solely measured by traditional metrics like citation counts as these have a lag time and are largely focused on an academic audience. There is increasing recognition to consider 'alternative metrics' or altmetrics to measure more immediate and broader impacts of research.

Article Synopsis
  • - Kinases dramatically speed up phosphoryl-transfer reactions, making them happen in milliseconds instead of the 8,000 years it would take without enzymes.
  • - The study focuses on adenylate kinase's catalytic process, utilizing methods like NMR, kinetics, and molecular simulations to dissect how it works at a microscopic level.
  • - Findings reveal that the magnesium cofactor enhances both the transfer of phosphate and the movement of the enzyme lid, indicating that adenylate kinases are finely tuned to activate crucial processes simultaneously through a well-organized active site.

The thermal conductance of individual single crystalline silicon nanowires with diameters less than 30 nm has been measured from 20 to 100 K. The observed thermal conductance shows unusual linear temperature dependence at low temperatures, as opposed to the T3 dependence predicted by the conventional phonon transport model. In contrast to previous models, the present study suggests that phonon-boundary scattering is highly frequency dependent, and ranges from nearly ballistic to completely diffusive, which can explain the unexpected linear temperature dependence.
