Effects of Mono- and Dicapsaicinoid Functionalization on the Physicochemical Properties and Antimicrobial Photodynamic Activity of Protoporphyrin IX. [PDF]

ChemMedChem
Capsaicin functionalization of Protoporphyrin IX influences aggregation behavior, lipophilicity, and photodynamic activity. A monosubstituted derivative exhibits enhanced antimicrobial photoinactivation of Staphylococcus aureus, whereas increased functionalization does not improve efficacy.

How Brazilian Public Universities Are Operationalizing The SDGs: Strategic Plans Analysis

Sustainable Development, EarlyView.
ABSTRACT Despite the importance of universities for Sustainable Development, only a handful of studies have evaluated the implementation levels of SDGs in HEIs in Latin America. To fill this void, this study examines the strategic plans of 70 Brazilian public universities, which account for 92.8% of Federal Universities.

Operationalising Circular Economy Through Social Innovation: A Systems Thinking‐Based Model for Sustainability Transitions

Sustainable Development, EarlyView.
ABSTRACT Social innovation (SI) is increasingly recognised as an important enabler of circular economy (CE) transitions. However, existing research offers limited explanation of the processes through which SI operationalises CE principles, as SI and CE have largely evolved in parallel and existing conceptualisations remain predominantly descriptive ...

Resonance‐Enhanced Four‐Wave Mixing Imaging for Mapping Defect Regions in Vanadium‐Doped WS2 Monolayers

Small Methods, EarlyView.
Resonant four‐wave mixing (FWM) microscopy reveals a spatial modulation of the third‐order nonlinear optical response in vanadium‐doped WS2 monolayers. This robust nonlinear contrast technique tracks the preferential accumulation of vanadium dopants along the structural bisection lines of the synthesized flakes.
