State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials

open access: yesAdvanced Materials, EarlyView.
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

COMPARATIVE ECONOMIC SYSTEMS

1980
Since the activities of individuals in the use of the means of production are regulated, at any given time and place, through the institutions then and there prevailing, the precise manner in which society will use its means of production will depend upon and be determined by the character of its economic institutions ...

Economics of Information Systems [PDF]

open access: possibleJournal of the American Statistical Association, 1971
Abstract n an information-processing chain, only the initial inputs (“environment”) and the terminal outputs (“actions”) affect directly the benefit to the user who maximizes its expected excess over cost. All intermediate flows (“symbols”) affect directly only costs and delays. Delays affect benefit non-additively, through “impatience” and, possibly, “
