Photoplethysmography for Measuring Cognitive Load in XR Environments: A Systematic Review

Advanced Sensor Research, Volume 5, Issue 3, March 2026.
ABSTRACT Photoplethysmography (PPG) is a low‐cost, low‐power biosensing technology with growing applications in education, particularly for monitoring cognitive load in eXtended Reality (XR) learning environments. Measuring cognitive load is critical for preventing overload and optimising immersive learning, yet existing approaches such as self‐reports

Giant Isotope Effect in Metal–Organic Frameworks Boosts Unprecedented Photo‐ and Radio‐Luminescence Enhancement

Advanced Science, Volume 13, Issue 14, 9 March 2026.
Deuterated MOFs in this work exhibited unprecedented giant luminescence isotope effect via O─H oscillator suppression, achieving maximal solid‐state materials emission enhancement. This yields significantly improved X‐ray detection sensitivity and imaging resolution, marking the first integration of MOFs with isotopic luminescence and opening new ...

Beyond Cocrystals: Hierarchical Functional Assemblies via Noncovalent Synthesis

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Non‐covalent interactions (NCIs) drive the formation of organic cocrystals with diverse structures and tunable optoelectronic properties. This review explores the essential factors governing these properties, highlighting how the sequential nucleation of cocrystals leads to the self‐assembly of organic hierarchical structures (OHSs).
