Interaction of linear manno-oligosaccharides with three mannose-specific bulb lectins. Comparison with mannose/glucose-binding lectins
(Elsevier, 1992-05-22)
Three new mannose-binding lectins, isolated from daffodil (NPA), amaryllis (HHA), and snowdrop (GNA) bulbs, are capable of precipitating with a linear mannopentaose (Man[alpha]1-3Man[alpha]1-3Man[alpha]1-3Man[alpha]1-2Man). ...
Fusion of mercury a new certified standard for differential scanning calorimetry
(Elsevier, 1990-03)
From the results of adiabatic-calorimetric measurements, mercury has been certified as a standard reference material for temperature and enthalpy of fusion for differential scanning calorimetry. The fusion temperature is ...
Interaction of five -mannose-specific lectins with a series of synthetic branched trisaccharides
(Elsevier, 1991-06-25)
The interaction of a series of synthetic, branched trisaccharides with five -mannose-specific lectins was studied by precipitation-inhibition assay. The branched methyl [alpha]--mannotrioside, [alpha]--Manp-(1-->3)-[[ ...
Boron-modified polysilylcarbodi-imides as precursors for Si–B–C–N ceramics: Synthesis, plastic-forming and high-temperature behavior
(John Wiley & Sons, Ltd., 1998-10)
The synthesis, by two different reaction pathways, of boron-modified polysilylcarbodi-imides of general type {B[C 2 H 4 Si(R)NCN] 3 } n (R 14=singly bonded organic ligand) and the plastic-forming and the thermal behavior ...
Thermodynamics of iron sulfides I. Heat capacity and thermodynamic properties of Fe9S10 at temperatures from 5 K to 740 K
(Elsevier, 1991-03)
Measurements of the heat capacity of Fe9S10 over the temperature range 5 K to 740 K reveal a first-order structural transition at 495 K and two higher-order transitions with maxima at 534 K and 591 K. The last two are of ...
Poly(organophosphazene)s and the sol–gel technique
(John Wiley & Sons, Ltd., 1999-05)
We report a survey of the utilization of phosphazene materials in combination with metal alkoxide precursors to form ceramics through the sol–gel technique. Silicon, titanium, zirconium and aluminum three-dimensional oxide ...
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 ...
Thermodynamic properties of silicides. II. Heat capacity at temperatures T from 5.9 K to 341 K and derived thermodynamic properties to T = 1200 K of tungsten disilicide: WSi2.06
(Elsevier, 1993-11)
The heat capacity of tungsten disilicide WSi2.06 was measured over the temperature range 5.9T/K)-2[middle dot]mol-1. For the lattice, the Debye characteristic temperature [Theta]CD = (317.8+/-3.3) K. From our results, the ...
Heating characteristics and atomic emission waveforms for glow discharge ion bombardment furnaces
(Elsevier, 1991)
Ion bombardment of a graphite cathode in a glow discharge plasma is used to heat the cathode to temperatures suitable for the vaporization of solution residues from the cathode surface. Two low-mass cathode configurations ...
Extraction of aminoglycoside antibiotics with reverse micelles
(John Wiley & Sons, Ltd., 1996-01)
The reverse micelle system of sodium di-2-ethylhexyl phosphate was used to extract aminoglycoside antibiotics, neomycin and gentamicin. The aminoglycosides can be efficiently extracted into a reverse micelle solution, and ...
