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 ...
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 ...
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 ...
Effect of gravity on Brownian flocculation
(Elsevier, 1984-09)
In previous analyses of simultaneous Brownian and gravity-induced flocculation, it has been assumed that each mechanism contributes independently to the total flocculation rate. In this paper the rigorous problem of coupled ...
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 ...
Stereochemistry in the cyclization of -azidophenylalkenes to indoles
(Elsevier, 1983)
- and --azidostilbene, -azido-[beta]-methylstilbene, and ()--azido[beta]-deuteriostyrene give indoles on thermolysis by a mechanism involving attack by a nitrene directly on the [beta] carbon atom, and not by insertion.

Extraction, separation and labeling with 14 C-glucose of hela cell polyglucose, RNA and DNA and comparison of the molecular weights and buoyant densities of polyglucose from poliovirus-infected and noninfected cultures
(Wiley Subscription Services, Inc., A Wiley Company, 1970-01)
The aqueous phase of phenol extracts of HeLa cells contains polyglucose (CHO) n , RNA, and DNA. These macromolecules were precipitated together and removed from 50% (v/v) ethanol solutions with a stirring rod. The viscous ...
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 ...
Transition dipole interaction in polypeptides: Ab initio calculation of transition dipole parameters
(Elsevier, 1984-06-15)
Ab initio calculations of dipole moment derivatives of a model system of N-methylacetamide hydrogen-bonded to two formamide molecules give values for amide I and amide II transition dipole moments consistent with those ...
