Early events of Bacillus anthracis germination identified by time-course quantitative proteomics
(WILEY-VCH Verlag, 2006-10)
Germination of Bacillus anthracis spores involves rehydration of the spore interior and rapid degradation of several of the protective layers, including the spore coat. Here, we examine the temporal changes that occur ...
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 ...
Thermophysics of metal alkanoates IV. Heat capacities and thermodynamic properties of potassium 2-methylpropanoate
(Elsevier, 1984-02)
The molar heat capacity of potassium 2-methylpropanoate, (CH3)2CHCO2K, has been measured between 8 and 350 K by adiabatic calorimetry, and found to be normal. The corresponding thermodynamic functions have been calculated. ...
Synthesis of [4.2]cyclophanes
(Elsevier, 1978)
Vinyl -xylylene cross-dimerizes with other xylylene-type intermediates to yield cycloadducts of the [8+6] and [6+6] type. This reaction provides a simple entry to the [4.2]paracyclophane system as well as the analogous ...
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 ...
Heat capacity of Th(NO3)4[middle dot]5H2O from 5 to 350 K
(Elsevier, 1976-01)
The heat capacity of crystalline Th(NO3)4[middle dot]5H2O has been determined by adiabatic calorimetry primarily to enable evaluation of the standard partial molar entropy and heat capacity of aqueous thorium(IV) ion. No ...
Low-Temperature SCR of NO with NH 3 over USY-Supported Manganese Oxide-Based Catalysts
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-04)
A series of catalysts of manganese oxide, manganese–cerium and iron–manganese oxide supported on USY (ultra-stable Y zeolite) were studied for the low-temperature selective catalytic reduction (SCR) of NO with ammonia in ...
