Transition-Metal Decorated Aluminum Nanocrystals.

ACS nano

Swearer DF, Leary RK, Newell R, Yazdi S, Robatjazi H, Zhang Y, Renard D, Nordlander P, Midgley PA, Halas NJ, Ringe E.
PMID: 28945360
ACS Nano. 2017 Oct 24;11(10):10281-10288. doi: 10.1021/acsnano.7b04960. Epub 2017 Oct 02.

Recently, aluminum has been established as an earth-abundant alternative to gold and silver for plasmonic applications. Particularly, aluminum nanocrystals have shown to be promising plasmonic photocatalysts, especially when coupled with catalytic metals or oxides into "antenna-reactor" heterostructures. Here, a...

Optimization of Three-Dimensional (3D) Chemical Imaging by Soft X-Ray Spectro-Tomography Using a Compressed Sensing Algorithm.

Microscopy and microanalysis : the official journal of Microscopy Society of America, Microbeam Analysis Society, Microscopical Society of Canada

Wu J, Lerotic M, Collins S, Leary R, Saghi Z, Midgley P, Berejnov S, Susac D, Stumper J, Singh G, Hitchcock AP.
PMID: 28893337
Microsc Microanal. 2017 Oct;23(5):951-966. doi: 10.1017/S1431927617012466. Epub 2017 Sep 12.

Soft X-ray spectro-tomography provides three-dimensional (3D) chemical mapping based on natural X-ray absorption properties. Since radiation damage is intrinsic to X-ray absorption, it is important to find ways to maximize signal within a given dose. For tomography, using the...

Draft Genome Sequence of Clostridium beijerinckii Ne1, Clostridia from an Enrichment Culture Obtained from Australian Subterranean Termite, Nasutitermes exitiosus.

Genome announcements

Wang H, Lin H, Tran-Dinh N, Li D, Greenfield P, Midgley DJ.
PMID: 25908128
Genome Announc. 2015 Apr 23;3(2). doi: 10.1128/genomeA.00303-15.

The draft genome of Clostridium beijerinckii strain Ne1 was reconstructed from the metagenomic sequence of a mixed-microbial consortium that produced commercially significant quantities of hydrogen from xylan as a sole feedstock. The organism possesses relatively limited hemicellulolytic capacity and...

High-resolution scanning precession electron diffraction: Alignment and spatial resolution.

Ultramicroscopy

Barnard JS, Johnstone DN, Midgley PA.
PMID: 28042983
Ultramicroscopy. 2017 Mar;174:79-88. doi: 10.1016/j.ultramic.2016.12.018. Epub 2016 Dec 25.

Methods are presented for aligning the pivot point of a precessing electron probe in the scanning transmission electron microscope (STEM) and for assessing the spatial resolution in scanning precession electron diffraction (SPED) experiments. The alignment procedure is performed entirely...

Entropic Comparison of Atomic-Resolution Electron Tomography of Crystals and Amorphous Materials.

Physical review letters

Collins SM, Leary RK, Midgley PA, Tovey R, Benning M, Schönlieb CB, Rez P, Treacy MMJ.
PMID: 29099194
Phys Rev Lett. 2017 Oct 20;119(16):166101. doi: 10.1103/PhysRevLett.119.166101. Epub 2017 Oct 16.

Electron tomography bears promise for widespread determination of the three-dimensional arrangement of atoms in solids. However, it remains unclear whether methods successful for crystals are optimal for amorphous solids. Here, we explore the relative difficulty encountered in atomic-resolution tomography...

Denoising time-resolved microscopy image sequences with singular value thresholding.

Ultramicroscopy

Furnival T, Leary RK, Midgley PA.
PMID: 27262768
Ultramicroscopy. 2017 Jul;178:112-124. doi: 10.1016/j.ultramic.2016.05.005. Epub 2016 May 10.

Time-resolved imaging in microscopy is important for the direct observation of a range of dynamic processes in both the physical and life sciences. However, the image sequences are often corrupted by noise, either as a result of high frame...

Resonances of nanoparticles with poor plasmonic metal tips.

Scientific reports

Ringe E, DeSantis CJ, Collins SM, Duchamp M, Dunin-Borkowski RE, Skrabalak SE, Midgley PA.
PMID: 26617270
Sci Rep. 2015 Nov 30;5:17431. doi: 10.1038/srep17431.

The catalytic and optical properties of metal nanoparticles can be combined to create platforms for light-driven chemical energy storage and enhanced in-situ reaction monitoring. However, the heavily damped plasmon resonances of many catalytically active metals (e.g. Pt, Pd) prevent...

Microstructural analysis of Au/TiO2-SBA-15 nanocomposite.

Microscopy and microanalysis : the official journal of Microscopy Society of America, Microbeam Analysis Society, Microscopical Society of Canada

Gondo T, Kaneko K, Nishiyama T, Yamada K, Saghi Z, Barnard JS, Midgley PA.
PMID: 24786633
Microsc Microanal. 2014 Aug;20(4):1001-7. doi: 10.1017/S1431927614000841. Epub 2014 May 01.

Properties of gold nanoparticles (AuNPs) are very different from bulk gold, in particular, highly dispersed AuNPs exhibit high catalytic activities on metal oxide supports. Catalytic activities of AuNPs are strongly dependent on: (i) size and morphology; (ii) synthesis methods;...

Faecal mimicry by seeds ensures dispersal by dung beetles.

Nature plants

Midgley JJ, White JD, Johnson SD, Bronner GN.
PMID: 27251393
Nat Plants. 2015 Oct 05;1:15141. doi: 10.1038/nplants.2015.141.

The large brown, round, strongly scented seeds of Ceratocaryum argenteum (Restionaceae) emit many volatiles found to be present in herbivore dung. These seeds attract dung beetles that roll and bury them. As the seeds are hard and offer no...

Academic Self-Handicapping and Achievement Goals: A Further Examination.

Contemporary educational psychology

Midgley C, Urdan T.
