What's the difference between thermochemical and thermochemistry?
Thermochemical
Definition:
(a.) Of or pertaining to thermochemistry; obtained by, or employed in, thermochemistry.
Example Sentences:
(1) A non-denatured DNA was obtained from epidermal sheets after a thermochemical treatment of biopsies (0.5 M ethylenediaminetetraacetic acid (EDTA), pH 7.5 at 60 degrees C for 90 seconds).
(2) The heat of combustion per mole of gas mixture at the lean limit is a reliable thermochemical criterion for the flammability of organic fuels with comparable reactivities.
(3) An algorithm computed the crater boundaries formed by a single laser pulse and the thermochemical damage around this crater.
(4) To further consider the thermochemical method as a useful approach for active transport research and to investigate the characteristic of a proton electrochemical potential (delta mu H+) across the membrane, the energetics of lactose active transport across Escherichia coli membrane vesicles coupled with an artificial electron donor (phenazine methosulfate-ascorbate) has been investigated.
(5) An interactive, PC-compatible FORTRAN program, STANJAN, was utilized in conjunction with thermochemical data sources to calculate equilibrium compositions of gas mixtures as a function of temperature.
(6) Optical and thermochemical properties of E. coli DNA molecules are compared in solutions containing poly(ethyleneglycol) (PEG) in concentrations at which compactization is not yet observed.
(7) At concentrations up to 10-fold excess, potential interferents [(CH3)3S+, (CH3)3Pb+] did not affect, significantly, the postulated thermochemical hydride generation (THG) process.
(8) Thermochemical cycle calculations using enthalpies of combustion and solution, entropies, solubilities, activity coefficients, and apparent molar heat capacities have also been performed.
(9) A specially built thermochemical death-rate apparatus is described which can be used to determine the resistance of microorganisms to ethylene oxide under controlled conditions.
(10) A numerical model is developed to predict zones of thermochemical tooth damage induced by laser radiation.
(11) Combination of results from calorimetric measurements and analytical determinations lead to valuable thermochemical information.
(12) The thermal and thermochemical survival responses of mammalian cells growing routinely at pH 7.4 are affected by extracellular pH.
(13) The determination of the equilibrium constant required the use of a thermochemical cycle calculation involving the following processes: (B) glucose 1-phosphate2-(aq) = glucose 6-phosphate2-(aq); (C) sucrose(aq) + HPO4(2-)(aq) = glucose 1-phosphate2-(aq) + fructose(aq); and (D) glucose 6-phosphate2-(aq) + H2O(liq) = glucose(aq) + HPO4(2-)(aq).
(14) This is precisely the principal difference which thermochemical arguments predict, since a y-type ion with N-terminal proline is estimated to be 32 kJ mol-1 more stable than with N-terminal alanine.
(15) The fact that arsenic pentoxide was also derivatized, and that no signal was observed in the absence of postthermospray hydrogen or the absence of cool diffusion flame, corroborated the thermochemically mediated arsine-generation mechanism.
(16) A thermochemical calculation of the composition of the volcanic gas suggests the following possibilities: (1) Large amounts of H2 and CO were present in the primitive atmosphere.
(17) The interpretation of calorimetric and respirometric measurements requires an energy balance approach in which experimentally measured CR ratios are compared with thermochemically derived oxycaloric equivalents.
(18) A novel high-performance liquid chromatography-atomic absorption spectrometry (HPLC-AAS) interface based on thermochemical hydride generation has been developed and optimized for the determination of arsenobetaine [(CH3)3As+CH2COOH], arsenocholine [(CH3)3As+CH2CH2OH], and tetramethylarsonium [(CH3)4As+] cations.
(19) Baxter and Lathe postulated that the effect of D arises from hydrogen bonding between D and the epsilon amino groups of surface lysine residues on FDPase, and it was found that molecules which resembled this group could block the alteration induced by D, presumably by competing with lysine residues for association with D. However, we find that the interaction between D and lysine in the presence of water is actually thermochemically repulsive, and that the presence of formamide does not affect the interaction between D and lysine, implying no useful complex formation between formamide and D. We were also unable to demonstrate that the blocking compounds consistently reduce toxicity when added to D rather than substituting for D, contrary to predictions based on complex formation between blocking compounds and D. In summary, it seems that present concepts of cryoprotectant toxicity are in need of serious revision.
(20) Acetate at a concentration of 0.1M (present in lignocellulosic hydrolysates from thermochemical processing) inhibited glucose utilization (about 50%) much more than xylose, and caused a decrease in product yield of about 30% for both sugars.
Thermochemistry
Definition:
(n.) That branch of chemical science which includes the investigation of the various relations existing between chemical action and that manifestation of force termed heat, or the determination of the heat evolved by, or employed in, chemical actions.
Example Sentences:
(1) After investigations by which thermochemistry was founded, respiration could be defined as a slow form of combustion.
(2) The prevalent consensus that the limits are controlled by natural convection is clearly demonstrated, and the complex interplay of kinetics and thermochemistry follows logically therefrom.
