Rock burst and slabbing failure and its influence on TBM excavation at headrace tunnels in Jinping II hydropower station

Two headrace tunnels and the drainage tunnel were excavated by tunnel boring machines (TBMs) in Jinping II Hydropower Station. During TBM excavation, two types of slabbing failure were encountered in these deep buried marble tunnels. One is rock bursting a ...

Insights into the Formation Mechanism of Rhodium Nanocubes

Paul Joseph Dyson, Ning Yan, Yuan Yuan

The mechanism of formation of rhodium nanocubes in the presence of tetradecyltrimethylammonium bromide and polyvinylpyrrolidone in ethylene glycol was studied in situ by XAFS, in conjunction with other ex situ techniques including MALDI-TOF MS, XRD, TEM, a ...

Ortho-II band folding in YBa2Cu3O7-delta films revealed by angle-resolved photoemission

Joël Mesot, Martin Mansson, Elia Razzoli

We present an angle-resolved photoelectron spectroscopy study of YBa2Cu3O7-delta films in situ grown by pulsed laser deposition. We have successfully produced underdoped surfaces with ordered oxygen vacancies within the CuO chains resulting in a clear orth ...

Hydrogen evolution catalyzed by electrodeposited nanoparticles at the liquid/liquid interface

Hubert Girault, Manuel Alejandro Méndez Agudelo, Peiyu Ge, Imren Hatay, Joonas Jalmari Nieminen

Aqueous protons reduction by decamethylferrocene in 1,2-dichloroethane can be catalyzed efficiently by platinum and palladium nanoparticles electrogenerated in situ at the liquid–liquid interface. ...

Label-free spectroscopic detection of vesicles in water using vibrational sum frequency scattering

Sylvie Roke, Hilton Barbosa De Aguiar

Vibrational sum frequency scattering (SFS) has been used to study sub-micron, catanionic vesicles in solution. The vesicles were synthesized from a binary mixture of dodecyltrimethylammonium bromide (DTAB) and sodium dodecylsulfate (SDS) surfactants in deu ...

Chiral Bronsted Acid-Catalyzed Enantioselective Multicomponent Mannich Reaction: Synthesis of anti-1,3-Diamines Using Enecarbamates as Nucleophiles

Jieping Zhu

Reaction of aldehydes, anilines, and enecarbamates in dichloromethane in the presence of EtOH and a catalytic amt. of chiral phosphoric acid I afforded the Mannich adducts which were in situ reduced to anti-1,2-disubstituted 1,3-diamines II in excellent di ...

Reduction of the Superconducting Gap of Ultrathin Pb Islands Grown on Si(111)

Wolf-Dieter Schneider, François Patthey, I-Po Hong

The energy gap Delta of superconducting Pb islands grown on Si(111) was probed in situ between 5 and 60 monolayers by low-temperature scanning tunneling spectroscopy. Delta was found to decrease from its bulk value as a function of inverse island thickness ...

Microfabricated Dual Sprayer for On-Line Mass Tagging of Phosphopeptides

Hubert Girault, Niels Erik Lion, Michel Prudent, Joël Stéphane Rossier

Phosphopeptides tagging reactions by dinuclear zinc(II) complexes (1,3-bis[bis(2-pyridylmethyl)amino]-propan- 2-olato dizinc(II)3+, called tag) were performed with a dual-channel microsprayer in electrospray ionization mass spectrometry. The reaction is fi ...
