Phase Segregation in Cs-, Rb- and K-Doped Mixed-Cation (MA).

Journal of the American Chemical Society

Kubicki DJ, Prochowicz D, Hofstetter A, Zakeeruddin SM, Grätzel M, Emsley L.
PMID: 28892374
J Am Chem Soc. 2017 Oct 11;139(40):14173-14180. doi: 10.1021/jacs.7b07223. Epub 2017 Sep 27.

Hybrid (organic-inorganic) multication lead halide perovskites hold promise for a new generation of easily processable solar cells. Best performing compositions to date are multiple-cation solid alloys of formamidinium (FA), methylammonium (MA), cesium, and rubidium lead halides which provide power...

Front Mol Neurosci. 2013 Nov 25;6:42. doi: 10.3389/fnmol.2013.00042. eCollection 2013.

Huntington's disease (HD) is a hereditary neurodegenerative disease caused by the expansion of a polyglutamine stretch in the huntingtin (HTT) protein and characterized by dysregulated calcium homeostasis. We investigated whether these disturbances are correlated with changes in the mRNA...

The photochemistry of two isomeric aryl diazo ketones was investigated by fs time-resolved UV-vis and IR spectroscopies. Both diazo ketone excited states decompose in less than 300 fs by multiple pathways. One pathway involves concerted Wolff rearrangement and nitrogen...

Evidence of hydrogen migration in an alkylphenyldiazirine excited state.

Organic letters

Zhang Y, Kubicki J, Platz MS.
PMID: 20572673
Org Lett. 2010 Jul 16;12(14):3182-4. doi: 10.1021/ol101127c.

Ultrafast photolysis (350 nm) of alkylphenyldiazirines promotes the diazirine to the S(1) excited state. Solvent and substituent effects on the excited state lifetimes indicate that the S(1) state is highly polarized and undergoes a [1,2]-H shift in concert with...

Mechanistic aspects of ketene formation deduced from femtosecond photolysis of diazocyclohexadienone, o-phenylene thioxocarbonate, and 2-chlorophenol.

The Journal of organic chemistry

Burdzinski G, Kubicki J, Sliwa M, Réhault J, Zhang Y, Vyas S, Luk HL, Hadad CM, Platz MS.
PMID: 23190449
J Org Chem. 2013 Mar 01;78(5):2026-32. doi: 10.1021/jo302023a. Epub 2012 Dec 26.

The photochemistry of diazocyclohexadienone (1), o-phenylene thioxocarbonate (2), and 2-chlorophenol (3) in solution was studied using time-resolved UV-vis and IR transient absorption spectroscopies. In these three cases, the same product cyclopentadienyl ketene (5) is formed, and two different mechanistic...

Analysis of phase sensitivity to longitudinal strain in microstructured optical fibers.

Optics express

Tenderenda T, Szostkiewicz L, Stanczyk T, Bienkowska B, Kunicki D, Murawski M, Mergo P, Piramidowicz R, Nasilowski T.

Opt Express. 2017 May 29;25(11):12216-12221. doi: 10.1364/OE.25.012216.

We investigate the influence of air holes on phase sensitivity in microstructured optical fibers to longitudinal strain. According to the numerical simulations performed, large air holes in close proximity to a fiber core introduce significant compression stress to the...

Laparoscopic treatment of a huge mesenteric pseudocyst - case report.

Intra-abdominal cysts and pseudocysts are rarely occurring lesions. Their incidence is reported to be 1 per 100 000-250 000 hospitalizations. The lesions' rarity and their mostly asymptomatic development causes troubles in early recognition and treatment. The patients' complaints are...

Methylammonium (MA)- and formamidinium (FA)-based organic-inorganic lead halide perovskites provide outstanding performance as photovoltaic materials, due to their versatility of fabrication and their power conversion efficiencies reaching over 22%. The proposition of guanidinium (GUA)-doped perovskite materials generated considerable interest...
