Motivated by the COVID-19 pandemic, the Hastings group has joined a new collaboration led by Dr. Bhattacharya (UK Chemical Engineering) to address the need for more breathable, antiviral masks. See the UK Research news article for more information.

New paper in RSC Advances: Rhodopseudomonas palustris-based conversion of organic acids to hydrogen using plasmonic nanoparticles and near-infrared light

Dec 13, 2019

UK ECE graduate student Mansoor Sultan has just published a paper in collaboration with the Bhattacharyya (UK Chemical Engr.) and Kim (UK Chemistry) groups. The paper addresses a new approach to clean energy production from waste streams using phototrophic bacteria and plasmonic nanoparticles.The full paper can be found at https://doi.org/10.1039/C9RA08747H.

New paper in Physical Review Letters: Spontaneous Magnetic Superdomain Wall Fluctuations in an Artificial Antiferromagnet

Nov 6, 2019

UK ECE postdoc Xiaoqian Chen and UK Physics graduate students Justin Woods and Barry Farmer have published a new paper in Physical Review Letters entitled "Spontaneous Magnetic Superdomain Wall Fluctuations in an Artificial Antiferromagnet." The work was carried out in collaboration with researchers at Lawrence Berkeley National Laboratory, Argonne National Laboratory, and Brookhaven National Laboratory. The effort used resonant, coherent soft X-ray scattering to study the behavior of nanomagnets in an artifical spin system.

New e-print on arXiv: A Hybrid Achromatic Metalens

Sep 17, 2019

UK Physics student Fatih Balli and UK ECE graduate students Mansoor Sultan and Sarah Lami have submitted an e-print entitled "A Hybrid Achromatic Metalens' that is currently under review for publication. The paper presents a new approach to designing and fabricating "flat" optics that can focus and image over a broad range of near-infrared wavelengths.

Jun 6, 2019

UK ECE graduate students Sarah Lami and Gabriel Smith, along with former Paul Lawrence Dunbar High School researcher Eric Cao, have just published a new paper related to nanoscale rapid prototyping and integrated circuit edit. The full paper can be be found at https://doi.org/10.1039/C9NR01857C

New paper in Nanotechnology: Altering the radiation chemistry of electron-beam lithography with a reactive gas: a study of Teflon AF patterning under water vapor

May 1, 2019

UK ECE graduate students Mansoor Sultan and Sarah Lami, along with collaborators in UK Physics, have published a new paper in Nanotechnology entitled, "Altering the radiation chemistry of electron-beam lithography with a reactive gas: a study of Teflon AF patterning under water vapor." The paper addresses a new approach to electron-beam lithography in which the exposure process is altered by the presence of water vapor. The full paper can be found at https://doi.org/10.1088/1361-6528/ab16f7.
