Efficient Sunlight Degradation of Wide‐Spectrum Antibiotics Through Enhanced Charge Separation in SnTCPP NPs‐Nb2C Schottky Heterojunction: Ultrafast Carrier Dynamic Study

open access: yesAdvanced Materials Interfaces, EarlyView.
Due to enhanced charge transfer and carrier mobility on the surface, the SnTCPP NPs‐Nb2C Schottky heterojunctions demonstrate exceptional sunlight‐driven catalytic activity toward tetracycline antibiotics and ofloxacin degradation, achieving a removal efficiency of up to 99.9% within 60 min of irradiation, both in model wastewater and natural water ...

Liberalismin lumo

open access: yesTutkimus & kritiikki
Artikkeli tarkastelee kahta kysymystä Michel Foucault'n uusliberalismitulkintaan liittyen: sitä, suhtautuiko hän itse asiassa uusliberalismiin positiivisesti, sekä sitä, kuinka kohdallinen hänen kuvauksensa siitä on. Tuloksena on, että hän näki uusliberaalin hallinnnan potentiaalisesti parempana kuin aiemmat hallinnan muodot, sekä ohitti ...

Printed SWCNT‐Based p–n Junction Thin‐Film Near‐Infrared Photoresistors Enabled by a Sustainable Furan‐Derived π‐Conjugated Polymer

open access: yesAdvanced Materials Technologies, EarlyView.
A sustainable polymer–carbon nanotube bilayer enables efficient near‐infrared photodetection in a simple lateral planar p–n junction thin‐film architecture. Thermal side‐chain cleavage enhances interfacial coupling, shifts the dominant photoresponse from 800 to 1000 nm, and substantially improves device performance.

Ligand‐Dependent Locally Excited and Charge‐Transfer Emission in Linear Copper(I) Mesoionic Carbene Luminophores

open access: yesAdvanced Optical Materials, EarlyView.
Ligand engineering enables precise control of emission in linear Cu(I) complexes by tuning donor–acceptor interactions between electron‐rich amines and π‐accepting mesoionic carbenes. Naphthyl‐substituted carbenes promote locally excited phosphorescence with vibronic structure, whereas electron‐rich amides combined with electron‐poor carbenes favor ...
