By thermodynamics, it is shown that the total Gibbs free energy of a closed system at constant temperature and pressure should diminish during an irreversible reaction, and that the equilibrium condition is achieved when (dG) t T,P = 0. Reversible reactions of first order have the ...
Catalysts derived from dimeric molybdenum(II) carboxylates on silica and their reactions w... The redox characteristics of the catalyst (i.e., Mo (VI) Mo (V)) induced by NO and CO treatments are reversible as shown by cycling of the NO ... S.A. Best and R.G. Squires and R.A....
A widely appreciated principle is that all reactions are fundamentally reversible. Observing reversible transition metal-catalysed reactions, particularly those that include the cleavage of C–C bonds, is more challenging. The development of palladium- and nickel-catalysed carboiodination reactions afforded ...

However, radical recombination reactions are often susceptible to undergo irreversible reactions, for example with molecular oxygen, moisture, and other surrounding molecules, which is a concern in the context of dynamic covalent chemistry20. In particular when exposed to ambient conditions for a long ...
The process is associated with distinct color changes. The dehydrated [M(H 2 pdc) 2 ] (M=Mn, Fe, Co, Ni, and Zn) are amorphous and highly reactive. Further chemical reactions of these reactive intermediates show that they may act as effective precursors towards assembly of new ...
The networks showed a completely reversible photoswitching of the conductance according to the photochromic reactions of the diarylethene units. The switching ... K Matsuda,H Yamaguchi,T Sakano,... - 《Journal of Physical Chemistry C》 被引量: 170发表: 2008年 Reversible Conductance Switching of Si...
Recently, stochastic simulations of networks of chemical reactions have shown distributions of steady states that are inconsistent with the steady state solutions of the corresponding deterministic ordinary differential equations. One such class of systems is comprised of networks that have irreversible reacti...
Functional mitochondria with an active membrane potential were visualized using a MitoTracker probe (200 nM for 20 min). Images are exemplarily shown for hNPCs of clone i1E4-R1-003 (Ctrl), and iR66-R1-007 (sPD); for DAns of clone i1E4-R1-003 (mitoTracker—Ctrl), iR66-R1-...
reactions to assess the Hadconcentration on the Pd surface. Two samples, Au/Pd and Au/Pd/ZIF-8, are employed to confirm the impact of hydrogen spillover on alkyne hydrogenation under light irradiation or heating conditions. The samples, Au/Pd and Au/Pd/ZIF-8, are the same as the models...
