Monolithic Electropromoted Reactor

Electrochemical promotion (EP) of catalysis has already been recognized as 'a valuable development in catalytic research' (J. Pritchard, 1990) and as 'one of the most remarkable advances in electrochemistry since 1950' (J. O'M. Bockris, 1996). Laboratory studies have clearly elucidated the phenomenology of electrochemical promotion and have proven that EP is a general phenomenon at the interface of catalysis and electrochemistry. The major progress toward practical utilization of EP is surveyed in this paper. The focus is given on the electropromotion of industrial ammonia synthesis catalyst, the bipolar EP and the development of a novel monolithic electropromoted reactor (MEPR) in conjunction with the electropromotion of thin sputtered metal films. Future perspectives of electrochemical promotion applications in the field of hydrogen technologies are discussed.

Abstract The characteristic of specialized computer programs has been presented, serving for identification of W. Budryk-S. Knothe theory parameters, used for description of asymptotic state of post-mining deformations, as well as for transient state. The software is the result of several years of authors’ work. It is a part of complete software system designed for forecasting of underground mining influences on the rock mass and land surface and graphical processing of calculations results. Apart from software description, a short example of its practical utilization has been attached.

Quality Of Research

When evaluating Quality of Science (QoS) in the context of development initiatives, it is essential to define adequate criteria. The objective of this perspective paper is to show how altmetric and bibliometric indicators have been used to support the evaluation of QoS in the 2020 Review of the Phase 2-CGIAR Research Programs (CRPs, 2017–2022), where, for the first time, the Quality of Research for Development (QoR4D) frame of reference has been utilized across the entire CGIAR CRP portfolio. Overall, the CRP review showed a significant output of scientific publications during the period 2017–2020, with 4,872 articles, 220,101 references, and 7.1 citations per article. Additionally, wider interest in scientific publications is demonstrated by good to high altmetrics, with average attention scores ranging from 70.8 to 806.9 with an average of 425.1. The use of selected bibliometrics was shown to be an adequate tool, for use together with other qualitative indicators to evaluate the QoS in the 12 CRPs. The CRP review process clearly demonstrated that standardized, harmonized and consistent data on research output is paramount to provide high-quality quantitative instruments and should be a priority throughout the transition toward One CGIAR. Therefore, we conclude that the QoR4D framework should be augmented by standardized bibliometric indicators embedded in measurement frameworks within the new One CGIAR. Finally, its practical utilization in monitoring and evaluation should be supported with clear guidelines.

Earth Abundant

AbstractHomogeneous earth-abundant metal catalysis based on well-defined molecular complexes has achieved great advance in synthetic methodologies. However, sophisticated ligand, hazardous activator and multistep synthesis starting from base metal salts are generally required for the generation of active molecular catalysts, which may hinder their broad application in large scale organic synthesis. Therefore, the development of metal cluster catalysts formed in situ from simple earth-abundant metal salts is of importance for the practical utilization of base metal resource, yet it is still in its infancy. Herein, a mixture of catalytic amounts of cobalt (II) iodide and potassium tert-butoxide is discovered to be highly active for selective hydroboration of vinylarenes and dihydroboration of nitriles, affording a good yield of diversified hydroboration products that without isolation can readily undergo further one pot transformations. It should be highlighted that the alkoxide-pinacolborane combination acts as an efficient activation strategy to activate cobalt (II) iodide for the generation of metastable heterotopic cobalt catalysts in situ, which is proposed to be catalytically active species.
