We present high-frequency angle-dependent EPR data for crystals of fNixZn1−xshmpdstBuEtOHdClg4 sx=1 and 0.02d. The x=1 complex behaves as a single-molecule magnet at low temperatures, displaying hysteresis and exceptionally fast magnetization tunneling. We show that this behavior is related to a fourth-order transverse crystal-field interaction, which produces a significant tunnel splitting s,1...

in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
Mortality rates of eggs and nauplii are essential for understanding and modelling dynamics of copepod populations. Abundances of Calanus finmarchicus females, eggs and nauplii were determined at 88 stations in the Labrador Sea. Egg production rates (EPRs) and egg and naupliar stage durations were calculated using published relationships with in situ chlorophyll concentration and temperature. Th...
A family of terbium probes was synthesized and evaluated for the luminescence detection of copper and zinc in water at neutral pH. Each probe incorporates a terbium ion chelated by a macrocyclic polyaminocarboxylate and conjugated to either one, two, or three phenanthridine antennas via a diamine linker. All three probes, Tb-1Phen, Tb-2Phen, and Tb-3Phen, exhibit similar responses toward copper...
The resolutions of metal-4-(2-pyridylazo)resorcinol chelates by capillary zone electrophoresis (CZE) were investigated in the presence of some interacting reagents; also, equilibrium reactions between the chelates and the interacting reagents were analyzed in an aqueous solution. Among nine metal chelates formed in aqueous solution, the chelates of VV, FeII, CoIII, NiII, and CuII were resolved ...
