cf. CA 55, 23400c. The Cu salt decompn. of diazo compds. in the presence of Ph3P opens up a new path to the synthesis of phosphorus-ylides. Ph3P (10 millimoles) and 10 millimoles 0.6M CH2N2 in Et2O treated 15 min. with 1 millimole anhyd. CuCl in 70 ml. tet ...
A new one pot, surfactant-free, synthetic route based on the surface organometallic chemistry (SOMC) concept has been developed for the synthesis of Sn surface-enriched Pt-Sn nanoparticles. Bu3SnH selectively reacts with [Pt]-H formed in situ at the surfac ...
Understanding the fundamental reactions accompanying the capture of carbon dioxide in amine solutions is critical for the design of high-performance solvents and requires an accurate modeling of the solute-solvent interaction. As a first step toward this g ...
We present a deformable cell culture system based on dielectric elastomer actuator (DEA). Understanding how the mechanical environment can affect cells functions could lead to significant advances in diseases diagnosis and drug development. Most available ...
A novel Ru-catalyzed hydrogenation of carbon dioxide proceeds with an unprecedented high formic acid to amine ratio (AAR of 2.69), which results in an improved energy content. The presented catalyst system allows for reversible fast hydrogen loading (even ...
Submicron atmospheric aerosol particles were collected during the Megacity Initiative: Local and Global Research Observation (MILAGRO) in March 2006 at three platforms located in the Mexico City urban area (at the Mexico City Atmospheric Monitoring System ...
The OH group in cyanohydrins RR1C(OH)CN [R = Me2CH, R1 = H; R = R1 = Me; RR1 = (CH2)4, (CH2)5] was protected with EtOCH:CH2 to give RR1C(CN)OCHMeOEt, which were then reduced by NaAlH2(OCH2CH2OMe)2 to RR1C(CHO)OCHMeOEt (I) (53-70%), which were hydrolyzed wi ...
Addnl. data considered in abstracting and indexing are available from a source cited in the original document. With a square-wave feed concn. variation, with a simple homogeneous or parallel reactions, a real advantage of periodic operation with a continuo ...
Fuel Cells are electrochemical devices that are able to directly convert chemical energy to electrical energy, without any Carnot limitation. Hence, their energy efficiencies are relatively high. Among the various types of fuel cells, solid oxide fuel cell ...
3-Methyl-2-geranylfuran (I, R = CH2CH:CMeCH2CH2CH:CMe2, R1 = Me) was prepd. by treating I (R = Li, R1 = Br) [prepd. from I (R = H, R1 = Br) and (Me2CH)2NLi] with BrCH2CH:CMeCH2CH2CH:CMe2 and methylating with MeI in THF contg. BuLi. I (R = CH2CH:CMe2, R1 = ...
