• One-step fabrication of GeSn branched nanowires 

  Doherty, Jessica; Biswas, Subhajit; McNulty, David; Downing, Clive; Raha, Sreyan; O'Regan, Colm; Singha, Achintya; O'Dwyer, Colm; Holmes, Justin D. (American Chemical Society, ACS, 2019-05-22)

  We report for the first time the self-catalyzed, single-step growth of branched GeSn nanostructures by a vapor–liquid–solid mechanism. These typical GeSn nanostructures consist of ⟨111⟩-oriented, Sn-rich (∼8 atom %) GeSn ...
• Detection of ultra-low protein concentrations with the simplest possible field effect transistor 

  Georgiev, Yordan M.; Petkov, Nikolay; Yu, Ran; Nightingale, Adrian M.; Buitrago, Elizabeth; Lotty, Olan; DeMello, John C.; Ionesco, Adrian M.; Holmes, Justin D. (IOP Publishing, 2019-05-08)

  Silicon nanowire (Si NW) sensors have attracted great attention due to their ability to provide fast, low-cost, label-free, real-time detection of chemical and biological species. Usually configured as field effect transistors ...
• Three-wavelength cavity-enhanced albedometer for measuring wavelength-dependent optical properties and single-scattering albedo of aerosols 

  Xu, Xuezhe; Zhao, Weixiong; Fang, Bo; Zhou, Jiacheng; Wang, Shuo; Zhang, Weijun; Venables, Dean S.; Chen, Weidong (OSA - The Optical Society, 2018-12-10)

  The spectral dependence of aerosol light absorption (αabs) and single-scattering albedo—[ω, defined as the ratio of the scattering (αscat) and extinction coefficients (αext = αabs + αscat)]—has proven effective in classifying ...
• Improving the accuracy and precision of broadband optical cavity measurements 

  Chen, Jun; Fullam, Donovan P.; Yu, Shuaishuai; Böge, Olaf; Le, Phuoc Hoa; Herrmann, Hartmut; Venables, Dean S. (Elsevier B.V., 2019-04-10)

  Most extinction measurements require a stable light source to attain high precision and accuracy. Here, we present a convenient approach to normalize light source intensity in broadband optical cavity measurements. In the ...
• An improved synthesis of adefovir and related analogues 

  Jones, David J.; O'Leary, Eileen M.; O'Sullivan, Timothy P. (Beilstein-Institut, 2019-03-29)

  An improved synthesis of the antiviral drug adefovir is presented. Problems associated with current routes to adefovir include capricious yields and a reliance on problematic reagents and solvents, such as magnesium ...
