The use of dielec. measurements to assign mol. configurations was examd. with model compds. of the chloroalkane, chloroalkene and chlorocumulene type. A dielec. microcell is described which allowed measurements of 0.35 mL samples under exclusion of air. Bo ...
This study explores the potential of MALDI-TOF MS for the mass measurement of large non-covalent protein complexes. The following non-covalent complexes have been investigated: aerolysin from Aeromonas hydrophila (335 kDa) and α-haemolysin from Staphylococ ...
Bromine contg. compds. are thought to play an important role in the O3 destruction in various regions of the atm. Recent studies of atm. Br chem. suggest that HOBr is one of the important Br compds. The rapid photolysis of HOBr in daytime releases Br atoms ...
We synthesized a molecule composed of two angiotensin II 4-8 pentapeptide fragments attached to a carrier molecule (TA), according to the template-assembled synthetic proteins concept. This molecule was investigated for receptor binding on angiotensin type ...
Transitions from the X 1SIGMA+ (v = 0) ground state of the carbon monoxide molecule to the electronically excited A 1PI(v = 0), B 1SIGMA+ (v = 0), and C 1SIGMA+ (v = 0) states have been studied by 2-photon laser induced fluorescence spectroscopy. Accurate ...
The dynamics of dipolar vortex solutions to the two-dimensional Euler equations is studied. A new type of nonlinear dipole is found and its dynamics in a slightly viscous system is compared with the dynamics of the Lamb dipole. The evolution of dipolar str ...
New exptl. methods are presented that allow one to measure cross-correlation between the fluctuations of dipolar interactions and chem. shift anisotropy (CSA) in scalar coupled systems with two and three spins I = 1/2 in isotropic soln. The methods involve ...
A zero-field spontaneous relaxor-ferroelectric transition is reported in Pb(Sc0.5Ta0.5)O3 (PST). This behavior is different from that of other relaxors, where such transitions occur only under the field. A highly disordered PST that has the wide relaxation ...
The recovery of four proteins by means of the classical reverse micellar two-phase system consisting of brine, AOT (Aerosol OT, sodium di-2-ethyl-1-hexyl sulfosuccinate), and iso-octane has been studied. A complete cycle of extn.-forward and backward- was ...
In this paper, we point out the specific aspects and difficulties of performing NMR of transition metal surfaces. We show how basic NMR techniques allowed us to determine molecular structures and rates of thermal decomposition of simple chemisorbed molecul ...
