Trosolwg

Mae Richard Johnston yn Athro yn y Ganolfan Ymchwil Deunyddiau, Prifysgol Abertawe, yn Gymrawd Cyfryngau Cymdeithas Wyddoniaeth Prydain 2013 (wedi'i leoli yn Nature), ac yn Gymrawd Sefydliad Cynaliadwyedd Meddalwedd 2015.

Gan ddefnyddio dull amlddisgyblaethol, mae ymchwil Richard wedi mynd ag ef o ddeallusrwydd artiffisial mewn gweithgynhyrchu, drwy ddeunyddiau tyrbin nwy (treuliadwyon, uwchaloion nicel, cyfansoddion matrics ceramig), ac ymlaen i ficrotomograffeg pelydr-X. Mae'n arwain y grŵp Delweddu pelydr-X yn Abertawe, ac yn cadeirio Grŵp Gweithredol Fforwm Ymchwil Prifysgol Abertawe (SURF). Mae hefyd yn Gyd-Gyfarwyddwr yr Academi Deunyddiau ac mae'n aelod o Bwyllgor Addysg Mwynau a Mwyngloddio'r Sefydliad Deunyddiau, yn ogystal â dyfeisio Gwobrau #ResearchAsArt a PI y rhaglen allgymorth ac ymgysylltu Deunyddiau: Live.
Wedi cipio grantiau ymchwil fel PI neu Co-I o dros £20 Miliwn ers 2014, ac mae'n Gyd-Gyfarwyddwr y ganolfan Delweddu Deunyddiau Uwch (AIM) gwerth £9M a ariennir gan EPSRC/LlC. Mae Richard yn lladmerydd dros gydweithio, ac yn hyrwyddwr ymgysylltu â'r cyhoedd gydag ymchwil.

Mae Richard wedi ysgrifennu ar gyfer Nature, Scientific American, The Guardian, Huffington Post, ac mae wedi gweithio ar raglenni dogfen teledu gyda'r BBC (Wildlife Patrol Rhys Jones) a Horizon (Animal Mummies).

Bioysbrydoliaeth

Uchafbwyntiau Gyrfa

Ymchwil

Mae ymchwil yn y JohnstonLab ym Mhrifysgol Abertawe yn nodweddiadol yn cwmpasu nifer o feysydd amrywiol, ond mae'n canolbwyntio'n bennaf ar nodweddiadu strwythurau gan ddefnyddio Microtomograffeg Pelydr-X. Mae gan y grŵp brofiad o ymchwilio i lawer o ddeunyddiau amrywiol, o sbesimenau planhigion a biolegol, i uwchaloion dwys.

Mae gennym ffocws ar fioddynwaredion a bioysbrydoliaeth gan ddefnyddio CT Pelydr-X i ymchwilio i fydoedd mewnol cudd natur, a meddwl am sut a pham y ffurfiwyd y strwythurau hyn. Yna, rydym yn chwilio am gymwysiadau peirianyddol heriol a allai elwa ar yr ysbrydoliaeth a gafwyd o'r elfennau pensaernïaeth naturiol hyn. Gan ddefnyddio argraffu 3D, gallwn greu replicâu neu brototeipiau cyflym o strwythurau a oedd gynt yn gudd ond a ganfuwyd drwy CT Pelydr-X, a ddangosir ar wrthrych bob dydd.

Mae'r grŵp hefyd yn ymchwilio i ddeunyddiau awyrofod, gan ganolbwyntio ar nodweddiadu dinistriol ac anninistriol haenau sgraffiniadwy, cyfansoddion matrics ceramig, ac uwchaloion nicel ymysg eraill. Hefyd, mae astudiaethau cyrydu o aloion sinc a dur yn parhau.

Hefyd, mae gan y grŵp arbenigedd ym maes cymhwyso deallusrwydd artiffisial i nifer o feysydd gan gynnwys gweithgynhyrchu, optimeiddio prosesau, ymgripiad metelau, a pherfformiad chwaraeon.

Mae cryfderau penodol mewn tomograffeg gyfrifiannol pelydr-X wedi arwain at gydweithio ym meysydd rhewlifeg, teffrocronoleg, meddygaeth adfywio, Eifftoleg, gwyddonwyr cyrydu, a llawer o rai eraill.

Yr ethos sylfaenol y tu ôl i’r gwaith yn JohnstonLab yw ein bod yn angerddol am ymchwil ryngddisgyblaethol a chydweithredol; a'r cyffro a'r egni a ddaw o weithio gydag ymchwilwyr o feysydd gwahanol iawn.

EG-283 Mechanical Deformation in Structural Materials

Following on from the first year module "Mechanical Properties" this module provides further detail about the deformation characteristics of a wide range of engineering materials. The course aims to develop the understanding of topics taught in the first year module by application to high performance materials such as titanium and nickel. Further understanding of deformation and damage mechanisms is gained through targeted units on elasticity, plasticity, alloy strengthening, mechanics of materials, fatigue and creep. The knowledge provided then allows for topics such as methods of mechanical testing and additive layer manufacturing. The module then seeks to draw these topics together by considering application to three main material classes, metals, ceramics and composites.
EG-381 Fracture and Fatigue

To provide a detailed understanding of fracture mechanics and fatigue of materials; relating to real-world case studies and current cutting-edge research. Failure of biological and engineered materials.
EGA163 Design and Laboratory Classes 1

This module is split into two parts. Firstly, Competence in engineering drawing using CAD. Secondly essential laboratory skills, including mechanical testing, microscopy (light, electron, X-ray), virtual reality to explore microstructures, and laboratory report writing and lab book keeping.
EGM402 Fracture and Fatigue

To provide a detailed understanding of fracture mechanics and fatigue modelling of materials; relating to real-world case studies and current cutting-edge research. Failure of biological and engineered materials.
EGSM11 Public Engagement and Science Communication

Group workshops, group discussion, and case studies will be used to give students an enhanced understanding of public engagement and science communication, and how they can develop content. It will highlight the importance of communicating science to publics. Using examples of science communication from different outlets and aimed at different audiences. The module will consider science communication from a researcher¿s point of view, and also journalism/press/media and how to work with science news outlets, consideration of funders and how to develop a public engagement initiative, and also from the perspective of the audience. Students will also learn about outreach and public engagement, linked to the Materials Live programme at Swansea University, and from a science engagement expert. This will be delivered off-campus to facilitate immersion in the topic, and remove the researchers temptation to delve into their every day work during the breaks. Group sessions will focus on developing and delivering talks, demonstrations, audience considerations, reach/engagement.

Mae Ymchwil fel Celf yn fenter ar draws y Brifysgol sy'n anelu at ddatblygu sgiliau ymgysylltu myfyrwyr a staff, ffrwythloni cydweithredu trawsddisgyblaethol, codi proffil ymchwil Abertawe a'i hymchwilwyr, a gwneud y Brifysgol yn lle gwell i astudio a gweithio. Mae'r prosiect yn darparu mecanwaith unigryw o allgymorth hygyrch ar gyfer pob ymchwil, gan arddangos y gwaith pwysig a phellgyrhaeddol, a hefyd agwedd ddynol ac emosiwn yr ymchwil sydd ar waith ym Mhrifysgol Abertawe i gynulleidfa amrywiol a newydd.

Mae cyflwyniadau'n waith celf neu ddelweddau trawiadol yn weledol ac yn destun hygyrch a diddorol – sy'n arwain at fenter wirioneddol unigryw.

Enillodd y ddelwedd hon wobr Ymchwilydd Gyrfa Gynnar yng nghystadleuaeth Ymchwil fel Celf 2013 Prifysgol Abertawe. Eglura'r peiriannydd Matt Carnie fod y celloedd solar hyn o arbrofion aflwyddiannus yn cynrychioli syniad sy'n gyfarwydd mewn gwyddoniaeth – "y tu ôl i bob llwyddiant mae llawer o adegau pan nad oedd pethau'n mynd yn ôl y bwriad".

Mae rhagor o wybodaeth am Ymchwil fel Celf ar gael yma.

Materials: Live!

Prosiect allgymorth ac ymgysylltu arloesol gan Brifysgol Abertawe, sy'n cyflwyno rhyfeddod gwyddoniaeth a pheirianneg deunyddiau i ddiddanu, ennyn brwdfrydedd ac addysgu darpar wyddonwyr a pheirianwyr y dyfodol. Mae Materials: Live! yn elfen hanfodol o'r "Academi Deunyddiau" yn Abertawe, prosiect mawr sy'n darparu ymchwil a hyfforddiant deunyddiau aml-lefel.

Darparu gweithgareddau sy'n cyfoethogi Cwricwlwm Cenedlaethol Gwyddoniaeth Cyfnodau Allweddol 1-4 yn ogystal â chwricwla Safon Uwch/UG.

Annog pobl i astudio gyrfaoedd sy'n gysylltiedig â phynciau STEM.

Ymgysylltu ag athrawon a chyflwyno gweithgareddau DPP i wella'r cynnwys y deunyddiau sy'n gysylltiedig â gwyddoniaeth yn eu gwersi.

Mwy o wybodaeth am Materials:Live! i'w gweld yma.

50/50

Mae 50/50 yn gydweithrediad celf/gwyddoniaeth/technoleg rhwng Rich a’r artist ffotograffau lleol Naomi Bowey, ac mae’n archwilio'r effeithiau y mae gwrthrychau'n eu cael ar ein hymddygiad – gan edrych ar fathau o gasglu, archifo a'r weithred orfodaethyrol o gronni. Mae Naomi yn manylu ar y prosesau sy'n gysylltiedig â synio, addasu, ac yn y pen draw cynhyrchu darn i'w arddangos yma. Gwefan arall
