Spin correlation in O(2) chemisorption on Ni(111).

Physical review letters

Kurahashi M, Yamauchi Y.
PMID: 25615482
Phys Rev Lett. 2015 Jan 09;114(1):016101. doi: 10.1103/PhysRevLett.114.016101. Epub 2015 Jan 09.

Molecular oxygen (O(2)) is a paramagnetic linear molecule, yet how its electron spin affects the chemisorption probability remains unclear. We here present the first spin- and alignment-resolved O(2) chemisorption experiment conducted with a single spin-rotational state-selected O(2) beam and...

Signal transduction and activator of transcription (STAT) proteins are extracellular ligand-responsive transcription factors that mediate cell proliferation, apoptosis, differentiation, development and the immune response. Aberrant signals of STAT induce uncontrolled cell proliferation and apoptosis resistance and are strongly involved...

Nickel-Catalyzed Reactions Directed toward the Formation of Heterocycles.

Acc Chem Res. 2015 Jun 16;48(6):1703-16. doi: 10.1021/acs.accounts.5b00041. Epub 2015 May 19.

Heterocycles have garnered significant attention because they are important functional building blocks in various useful molecules, such as pharmaceuticals, agricultural chemicals, pesticides, and materials. Several studies have been conducted regarding the preparation of heterocyclic skeletons with an emphasis on...

Chiral Recognition of 2-Alkylalcohols with Magnetic Circular Dichroism Measurement of Porphyrin J-Aggregate on Silica Gel Plate.

Analytical chemistry

Anal Chem. 2016 May 03;88(9):4619-23. doi: 10.1021/acs.analchem.6b00515. Epub 2016 Apr 22.

Simple chiral recognition method of 2-alkylalcohols on a silica gel plate was proposed by using the induced circular dichroism (ICD) of J-aggregates of diprotonated tetraphenylporphyrin and magnetic circular dichroism (MCD) spectrometry. To the silica gel on a glass slide...

Intensive Care Med Exp. 2015 Dec;3(1):56. doi: 10.1186/s40635-015-0056-z. Epub 2015 Jun 19.

BACKGROUND: Patients with acute respiratory distress syndrome receiving mechanical ventilation show inhomogeneous lung aeration. Atelectasis during uneven mechanical ventilation leads to alveolar hypoxia and could therefore result in lung inflammation and injury. We aimed to elucidate whether and how...

Nickel-catalysed synthesis of tetrasubstituted vinyl sulfides from thiocarbamates and internal alkynes.

Chemical communications (Cambridge, England)

Chem Commun (Camb). 2015 Jan 25;51(7):1285-8. doi: 10.1039/c4cc09123j.

The thiocarbamoylation of internal alkynes to produce tetrasubstituted β-aminocarbonyl vinyl sulfides was demonstrated using a nickel catalyst. This reaction was successful with a wide variety of substituents, and gave the syn-adducts exclusively.

Communication: fully alignment-specified O2 chemisorption on vicinal Si(100).
