Self-Catalyzed Vapor-Liquid-Solid Growth of Lead Halide Nanowires and Conversion to Hybrid Perovskites.

Nano letters

Meyers JK, Kim S, Hill DJ, Cating EEM, Williams LJ, Kumbhar AS, McBride JR, Papanikolas JM, Cahoon JF.
PMID: 29111750
Nano Lett. 2017 Dec 13;17(12):7561-7568. doi: 10.1021/acs.nanolett.7b03514. Epub 2017 Nov 13.

Lead halide perovskites (LHPs) have shown remarkable promise for use in photovoltaics, photodetectors, light-emitting diodes, and lasers. Although solution-processed polycrystalline films are the most widely studied morphology, LHP nanowires (NWs) grown by vapor-phase processes offer the potential for precise...

ACS Appl Mater Interfaces. 2017 Oct 25;9(42):37105-37111. doi: 10.1021/acsami.7b08162. Epub 2017 Oct 11.

Although silicon (Si) nanowires (NWs) grown by a vapor-liquid-solid (VLS) mechanism have been demonstrated for a range of photonic, electronic, and solar-energy applications, continued progress with these NW-based technologies requires increasingly precise compositional and morphological control of the growth...

Capillarity-Driven Welding of Semiconductor Nanowires for Crystalline and Electrically Ohmic Junctions.

Nano letters

Celano TA, Hill DJ, Zhang X, Pinion CW, Christesen JD, Flynn CJ, McBride JR, Cahoon JF.

Nano Lett. 2016 Aug 10;16(8):5241-6. doi: 10.1021/acs.nanolett.6b02361. Epub 2016 Aug 01.

Semiconductor nanowires (NWs) have been demonstrated as a potential platform for a wide-range of technologies, yet a method to interconnect functionally encoded NWs has remained a challenge. Here, we report a simple capillarity-driven and self-limited welding process that forms...

Electrostatic tip effects in scanning probe microscopy of nanostructures.

Nanotechnology

Casper CB, Ritchie ET, Teitsworth TS, Kabos P, Cahoon JF, Berweger S, Atkin JM.
PMID: 33477125
Nanotechnology. 2021 May 07;32(19):195710. doi: 10.1088/1361-6528/abde63.

Electrical scanning probe microscopies (SPM) use ultrasharp metallic tips to obtain nanometer spatial resolution and are a key tool for characterizing nanoscale semiconducting materials and systems. However, these tips are not passive probes; their high work functions can induce...

Association between exposure to radioactive iodine after the Chernobyl accident and thyroid volume in Belarus 10-15 years later.

Environmental health : a global access science source

Chirikova E, McConnell RJ, O'Kane P, Yauseyenka V, Little MP, Minenko V, Drozdovitch V, Veyalkin I, Hatch M, Chan JM, Huang CY, Mabuchi K, Cahoon EK, Rozhko A, Zablotska LB.

Environ Health. 2022 Jan 07;21(1):5. doi: 10.1186/s12940-021-00820-0.

BACKGROUND: While there is a robust literature on environmental exposure to iodine-131 (METHODS: To assess the effect of RESULTS: The analysis was based on 10,703 subjects. We found a statistically significant positive association between radiation dose and thyroid volume...

Longitudinal metabarcode analysis of karst bacterioplankton microbiomes provide evidence of epikarst to cave transport and community succession.

PMID: 33732542
PeerJ. 2021 Mar 08;9:e10757. doi: 10.7717/peerj.10757. eCollection 2021.

Caves are often assumed to be static environments separated from weather changes experienced on the surface. The high humidity and stability of these subterranean environments make them attractive to many different organisms including microbes such as bacteria and protists....

Mitochondrial mRNA Processing in the Chlorophyte Alga .

Plants (Basel, Switzerland)

Proulex GCR, Meade MJ, Manoylov KM, Cahoon AB.
PMID: 33803683
Plants (Basel). 2021 Mar 18;10(3). doi: 10.3390/plants10030576.

Mitochondria carry the remnant of an ancestral bacterial chromosome and express those genes with a system separate and distinct from the nucleus. Mitochondrial genes are transcribed as poly-cistronic primary transcripts which are post-transcriptionally processed to create individual translationally competent...

Breast cancer risk in residents of Belarus exposed to Chernobyl fallout while pregnant or lactating: standardized incidence ratio analysis, 1997 to 2016.

International journal of epidemiology

Int J Epidemiol. 2021 Oct 23; doi: 10.1093/ije/dyab226. Epub 2021 Oct 23.

BACKGROUND: Pregnancy and lactation may constitute radiation-sensitive reproductive periods due to rapid cell proliferation and concentration of radioiodine in the lactating breast. However, there are limited epidemiological data among women exposed to radiation during these periods.METHODS: We examined incidence...

Plasma and vacuolar membrane sphingolipidomes: composition and insights on the role of main molecular species.

Plant physiology

Carmona-Salazar L, Cahoon RE, Gasca-Pineda J, González-Solís A, Vera-Estrella R, Treviño V, Cahoon EB, Gavilanes-Ruiz M.

Lipid structures affect membrane biophysical properties such as thickness, stability, permeability, curvature, fluidity, asymmetry, and interdigitation, contributing to membrane function. Sphingolipids are abundant in plant endomembranes and plasma membranes (PMs) and comprise four classes: ceramides, hydroxyceramides, glucosylceramides, and glycosylinositolphosphoceramides...
