A new cobalt(II) phosphate compd. has been synthesized using high-temp. flux methods in the CsCl/NaCl media at 650°C. The title compd., Na3CsCo7(PO4)6, forms vibrant purple plate crystals. It crystallizes in a monoclinic space group C2/c (no. 15) with the ...
This project aims at the optimization of chemical reactions by using online analytical and chemometric methods. The experiments are carried out in a fully automated chemical reactor (1 liter). The host computer controls the standard process variables such ...
A new potential energy surface and dipole moment surface were constructed for BrHI- by a 3-D spline interpolation of ab initio data at the MRCI/aVQZ level of theory and basis set, with ECP's for the halogens. "Exact"vibrational calcns. were performed on th ...
The novel versatile Co(I) tris-carbene complex [(TIMENxyl)Co]Cl (1) (TIMEN = (tris[2-(3-aryl-2,3-dihydro-1H-imidazol-2-ylidene)ethyl]amine)) reacts with CO, 1-electron oxidizers such as CH2Cl2, and O2 to yield the Co complexes [(TIMENxyl)Co(CO)]Cl (2), [(T ...
We describe a new apparatus that combines pulsed laser excitation in a molecular beam with surface-science methods for preparation of clean single-crystal surfaces and detection of adsorbates to enable state-selected studies of gas-surface reaction dynamic ...
We report on long-range interactions between adsorbates on metal surfaces with a surface state. A comparison of three adsorbate/substrate systems [Cu/Cu(111), Co/Cu(111), and Co/Ag(111)] suggests the general existence of such interactions and shows up comm ...
The first part of this laboratory study deals with heterogeneous reactions of bromine- and chlorine-containing species relevant to the atmosphere with solid model alkali salt substrates. The second part of this work treats the heterogeneous interaction of ...
Glucose and lactate profiles in Chinese hamster ovary cell cultures were accurately monitored in real time and in situ during three bioreactor batch cultures lasting 11, 15, and 15 days performed within a 60-day period. Monitoring was accomplished using in ...
Over the past decade the interest for bioprocess monitoring using non-invasive IR spectroscopic sensors has increased considerably. This is mainly due to their rapid simultaneous multi-analyte detn. ability, in-situ sterilizability, and low need for mainte ...
The development of the interfacial bond strength as a function of bonding conditions has been investigated in two representative semicrystalline thermoplastics, isotactic polypropylene and polyamide 12. If one side of the interface is well above the meltin ...
