Atomic Scale Engineering of Multivalence‐State Palladium Photocatalyst for Transfer Hydrogenation with Water as a Proton Source

Advanced Materials, EarlyView.
Photocatalytic transfer hydrogenation is achieved over a multivalence‐state palladium photocatalyst, in which protons generated from photocatalytic water splitting are added to unsaturated double bonds. The operando light‐induced Electron Paramagnetic Resonance (EPR) spectroscopy confirms the synergistic action between Pd single atoms and nanoparticles,

Evaluation of three methods for hemoglobin measurement in a blood donor setting

São Paulo Medical Journal, 1999
CONTEXT: The hemoglobin (Hb) level is the most-used parameter for screening blood donors for the presence of anemia, one of the most-used methods for measuring Hb levels is based on photometric detection of cyanmetahemoglobin, as an alternative to this ...

Thermionics in Topological Materials

Advanced Materials, EarlyView.
Thermionics is one of the fundamental energy conversion mechanisms in solid state systems. Recent development in topological materials opens new avenues in developing thermionic systems and devices. Due to the linear energy dispersion and topological protection of charge transport, these new materials are promising candidates for high efficiency ...

Low compliance with alcohol gel compared with chlorhexidine for hand hygiene in ICU patients: results of an alcohol gel implementation program

Brazilian Journal of Infectious Diseases
Although the introduction of alcohol based products have increased compliance with hand hygiene in intensive care units (ICU), no comparative studies with other products in the same unit and in the same period have been conducted.

Dipole Oscillations of a Bose-Einstein Condensate in Presence of Defects and Disorder [PDF]

Phys. Rev. Lett. 100, 250405 (2008), 2008
We consider dipole oscillations of a trapped dilute Bose-Einstein condensate in the presence of a scattering potential consisting either in a localized defect or in an extended disordered potential. In both cases the breaking of superfluidity and the damping of the oscillations are shown to be related to the appearance of a nonlinear dissipative flow ...

Combining X‐Ray Photoelectron and Absorption Spectroscopies for Determining Surface Chemistry and Composition of Ti3C2Tx MXene

Advanced Materials Interfaces, EarlyView.
The surface chemistry and core composition of Ti3C2Tx MXenes is often derived from X‐ray Photoelectron Spectroscopy (XPS) but its determination and quantification remain difficult due to adsorbed species such as adventitious carbon. This challenge is overcome by using energy‐dependent XPS and depth profile modeling of the Ti3C2Tx MXene surface ...

Physicians' attitude towards tobacco dependence in a private hospital in the city of São Paulo, Brazil

Einstein (São Paulo)
OBJECTIVE: To investigate how often physicians identify and treat tobacco dependence and whether characteristics as gender, age, marital status, medical specialty and smoking status can influence their attitude towards this question.

Albert Einstein online

First Monday, 1997
The power of the World Wide Web, it is commonly believed, lies in the vast information it makes available; "Content is king," the mantra runs. This image creates the conception of the Internet as most of us envision it: a vast, horizontal labyrinth of pages which connect almost arbitrarily to each other, creating a system believed to be "democratic" in
