An introductory review is given to the study of two-dimensional phase transitions, as most easily observed on lamellar solids. Two examples have been chosen, namely the xenon-graphite and krypton-graphite couples, which have been the subject of the most extensive and detailed studies. These ...
Rate constants for the reaction of OH radicals with CHF$sub 2$Cl, CF$sub 2$Cl$sub 2$, CFCl$sub 3$, and H$sub 2$ were determined over the temperature range 297 to 434$sup 0$K using a flash photolysis--resonance fluorescence technique. The... R Atkinson,DA Hansen,JN Pitts 被引量...
The reaction C(s)+2H_(2)(g)⇌CH_(4)(g) has K_(p)=0.263 at 1000.K . Calculate the total pressure at equilibrium when 5.135g of H_(2) and 23.58g of C(s) are placed in a 8.21 L flask an...

The CTAB-Pd/GAC catalyst was obtained by functionalizing palladium/granular activated carbon (Pd/GAC) with cetyltrimethylammonium bromide (CTAB), which was used for the electrocatalytic reductive dechlorination of 2,4-dichlorobenzoic acid (2,4-DCBA). The degradation rate of 2,4-DCBA by 40 mg...
Reaction of the organolithium reagent (Me3Si)2C(SiMe2Ph)Li, R′Li, with Me2SiHCl, Et2SiHCl, Et2SiF2 and Et2SiCl2 gives the products R′SiMe2H, R′SiEt2H, R′SiEt2F and R′SiEt2Cl, respectively.关键词: VISCOSITY B-COEFFICIENT AZIDE ANION CYANIDE ANION ...
α-Methylstyrene and α-phenylstyrene were also competent substrates (2g, 2h). Gratifyingly, the reaction was also compatible with the use of di- and trisubstituted aliphatic alkenes and 1,3-dienes (2i–2l). The reaction of 2-methyl-2-butene produced non-conjugated β,γ-unsaturated ...
reaction conditions. The ECSAs of CDFs and GNSs are determined to be 0.50 ± 0.21 and 0.41 ± 0.04 cm2, based on the reduction peaks of AuO peaks with a double layer correction and a charge density of 390 μC cm−2in 0.1 M HClO4, respectively (Supplementary ...
