Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis

Advanced Materials, EarlyView.
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

Side‐Chain‐Induced Interlayer Slipping in Metalloporphyrin COFs Enables Microenvironment and Spin‐State Regulation for Photocatalytic CO2 Reduction

Advanced Materials, EarlyView.
Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?

Advanced Robotics Research, EarlyView.
Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...

The Republic of South Africa

Czech Journal of International Relations, 2014
This text deals with the development assistance of the Republic of South Africa after the fall of the apartheid era. The article is framed by the theory of South-South cooperation, which was established in the 1950’s and has risen since the beginning of

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

Advanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Single‐Cell Transcriptomic Analysis of Tumor Heterogeneity and the Microenvironment in Pseudomyxoma Peritonei

Advanced Science, EarlyView.
This study presents a single‐cell atlas of pseudomyxoma peritonei spanning primary and paired metastatic lesions. Distinct epithelial substates, stromal remodeling, immune exclusion, lipid metabolic reprogramming, and a candidate angiogenic network were identified in metastatic lesions.

Does China’s Aid in Africa Affect Traditional Donors?

International Studies: Interdisciplinary Political and Cultural Journal, 2019
China’s role as an emerging aid provider and the concept of a social plan in Africa has led to polarised responses in the West. Several say that this “productivist” strategy is much less determined by the concepts of citizenship, legal, social rights ...
