Scientists create 3D-printed, microscopic gas sensors - painters’ pallets without even a hint of pigment

"The tiny responsive arrays, which are smaller than a freckle, can be used to tell us an enormous amount about the chemistry of their environment”


Scientists from Trinity College Dublin and AMBER, the SFI Research Centre for Advanced Materials and BioEngineering Research, have discovered a way to fabricate tiny colour-changing gas sensors using new materials and a high-resolution form of 3D printing. The sensors – responsive, printed, ...

Physicists create world's smallest engine


Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine - which, as a single calcium ion, is approximately ten billion times smaller than a car engine. Work performed by Professor John Goold's QuSys group in Trinity's ...

Giant molecular cages for energy conversion and drug delivery


Scientists from Trinity College Dublin and AMBER, the Science Foundation Ireland-funded materials science research centre hosted in Trinity College Dublin, have created 'molecular cages' that can maximise the efficiency of converting molecules in chemical reactions, and that may in future also be ...

2017 WITec Paper Award for Outstanding Scientific Publications


From nearly 60 submissions for the 2017 WITec Paper Award, our jury selected the three best publications. They were written by scientists from Ireland, Portugal and Germany who used WITec correlative confocal Raman microscopes to study transition metal dichalcogenides, textile fibers and cement. ...

Major breakthrough in smart printed electronics


Researchers in AMBER, the Science Foundation Ireland-funded materials science research centre hosted in Trinity College Dublin, have fabricated printed transistors consisting entirely of 2-dimensional nanomaterials for the first time. These 2D materials combine exciting electronic properties with ...

Scientists reveal origin of Earth's oldest crystals

The crystals probably formed in huge impact craters some 4 billion years ago


New research suggests that the very oldest pieces of rock on Earth -- zircon crystals -- are likely to have formed in the craters left by violent asteroid impacts that peppered our nascent planet, rather than via plate tectonics as was previously believed. Rocks that formed over the course of ...


'Goldilocks material' could change spintronics


Attempting to develop a novel type of permanent magnet, a team of researchers at Trinity College in Dublin has discovered a new class of magnetic materials based on Mn-Ga alloys.Described as a zero-moment half metal in Applied Physics Letters, from AIP Publishing, the new Mn2RuxGa magnetic alloy ...
