MICROMORPHOGENESIS DURING DIATOM WALL FORMATION PRODUCES SILICEOUS NANOSTRUCTURES WITH DIFFERENT PROPERTIES(1).

Journal of phycology

Crawford SA, Chiovitti A, Pickett-Heaps J, Wetherbee R.
PMID: 27032593
J Phycol. 2009 Dec;45(6):1353-62. doi: 10.1111/j.1529-8817.2009.00759.x. Epub 2009 Nov 13.

Micromorphogenesis within the silica deposition vesicle (SDV) of the diatom Pinnularia viridis (Nitzsh) Ehrenb. resulted in distinct silica nanostructures and layers within forming valves and girdle bands. These siliceous components were similarly disclosed following alkaline etching of mature valves/girdle...

Nano Lett. 2014 Aug 13;14(8):4792-6. doi: 10.1021/nl501969k. Epub 2014 Jul 17.

Hydrogen spillover is of great importance to understanding many phenomena in heterogeneous catalysis and has long been controversial. Here we exploit well-defined nanoparticles to demonstrate its occurrence through evaluation of CO2 methanation kinetics. Combining platinum and cobalt nanoparticles causes...

Biome-scale nitrogen fixation strategies selected by climatic constraints on nitrogen cycle.

A novel main-chain polyfullerene, poly[fullerene-alt-2,5-bis(octyloxy)terephthalaldehyde] (PPC4), is investigated for its hypothesized superior morphological stability as an electron-accepting material in organic photovoltaics relative to the widely used fullerene phenyl-C61-butyric acid methyl ester (PCBM). When mixed with poly(3-hexylthiophene-2,5-diyl) (P3HT), PPC4 affords...
