NATIONAL SECURITY AND BORDER MANAGEMENT IN WEST AFRICA: A STUDY OF NIGERIA-NIGER RELATIONS

open access: yesInternational Studies Journal
National Security and Border Management in West Africa is an important discourse in security studies in a time when high insecurity and other crimes such as terrorism, kidnapping, arms and weapons smuggling are pervasive. This paper seeks to outline the

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing

open access: yesAdvanced Science, EarlyView.
Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...

Pressure‐Induced Drift Artifacts in Stretchable Liquid Metal ThinFilm Electrocardiogram Electrodes

open access: yesAdvanced Science, EarlyView.
A stretchable LM electrode integrated with a strain sensor enables in situ quantitative investigation of drift artifact and skin deformation. This reveals the significance of pressure‐induced drift artifact and its intimate relationship with the skin potential model.

Generation of Self‐Organizing Macrovascular Constructs by Bioprinting Human iPSC‐Derived Mesodermal Progenitor Cells

open access: yesAdvanced Science, EarlyView.
ABSTRACT Vascularization remains a major obstacle in tissue engineering. Here, we introduce a bioprinting strategy to generate centimeter‐scale, self‐organizing “mother vessel” constructs from iPSC‐derived hiMPCs. By optimizing bioink composition, printing was accomplished in a single‐step approach. Within one week, hiMPCs differentiated into both CD31+

Unconstrained Coordination of Pt Single Atoms on Distorted g‐C3N4 Enables Electronic Flexibility and Enhanced Microplastics Photoreforming

open access: yesAdvanced Science, EarlyView.
This study reveals Pt single atoms anchored on distorted graphitic carbon nitride, exhibiting flexible coordination and enhanced interfacial charge transfer. Combined spectroscopy and DFT reveal asymmetric Pt─N environments that promote photoreforming of microplastics into hydrogen, demonstrating a solar‐driven pathway for plastic upcycling with ...
