Pyrolytic conversion of precursors prepared in Ti(NMe 2 ) 4 –diamine systems
(John Wiley & Sons, Ltd., 1998-10)
Precursors possessing Ti–N bonds were prepared by the reactions between Ti(NMe 2 ) 4 and each of three diamines H 2 NCH 2 CH 2 NH 2 , Me(H)NCH 2 CH 2 N(H)Me, HN(CH 2 CH 2 ) 2 NH (Ti(NMe 2 ) 4 :diamine 14= 141:2), and were ...
Development of a capillary high-performance liquid chromatography tandem mass spectrometry system using SWIFT technology in an ion trap/reflectron time-of-flight mass spectrometer
(John Wiley & Sons, Ltd., 1997-10-30)
In this work a capillary high-performance liquid chromatography/tandem mass spectrometry system has been developed in a quadrupole ion trap/reflectron time-of-flight mass spectrometer. The broadband excitation for isolating ...
Rapid screening of protein profiles of human breast cancer cell lines using non-porous reversed-phase high performance liquid chromatography separation with matrix-assisted laser desorption/ionization time-of-flight mass spectral analysis
(John Wiley & Sons, Ltd., 1999-09-30)
Non-porous reversed-phase (NP-RP) HPLC has been used to rapidly generate protein profiles of whole cell lysates of human breast cancer cell lines. The non-porous packing material used was silica coated with C18, which ...
Rate processes on fractals: Theory, simulations, and experiments
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1986-01)
Heterogeneous kinetics are shown to differ drastically from homogeneous kinetics. For the elementary reaction A + A → products we show that the diffusion-limited reaction rate is proportional to t − h[A] 2 or to [A] x , ...
A rapid and sensitive screening method for the detection of anti-2-acetylaminofluorene immunoglobulins
(Elsevier, 1988-04-22)
A method is described in which anti-2-acetylaminofluorene immunoglobulins may be detected using a simple and sensitive screening procedure. The method is based on immunoglobulin binding of an 125I derivatized 2-aminofluorene ...
Focus on function: Single molecule RNA enzymology
(Wiley Subscription Services, Inc., A Wiley Company, 2007-12-05)
The ability of RNA to catalyze chemical reactions was first demonstrated 25 years ago with the discovery that group I introns and RNase P function as RNA enzymes (ribozymes). Several additional ribozymes were subsequently ...
Shape-selective separation of polycyclic aromatic hydrocarbons by reversed-phase liquid chromatography on tetraphenylporphyrin-based stationary phases
(Elsevier, 1993-07-02)
The reversed-phase chromatographic behavior of planar and non-planar polycyclic aromatic hydrocarbons (PAHs) is investigated on tetraphenylporphyrin and two metallotetraphenylporphyrin [Sn(IV), In(III)] bonded stationary ...
Effect of Dopants on Zirconia Stabilization—An X-ray Absorption Study: III, Charge-Compensating Dopants
(Blackwell Publishing Ltd, 1994-05)
Optically detected zero field magnetic resonance of phosphorous activated alkali halide crystals
(Elsevier, 1977-10-15)
Optically detected zero field magnetic resonance (ODMR) has been utilized to obtain the fine structure parameters |D| and |E| of the phosphorescent color center in phosphorous activated potassium chloride and bromide single ...
The vibrational relaxation of I2I2 (X 1Σg+)(X1Σg+) in mesitylene
(The American Institute of Physics, 1998-03-22)
Transient absorption measurements between 400 nm and 570 nm are used to extract information on the vibrational relaxation of iodine in the complexing solvent mesitylene. The well characterized nature of the I2I2-arene ...
