Monitoring Injected Drug Use in Greece Through Syringe Residue Analysis: A Multicity Study Within the ESCAPE Network

Drug Testing and Analysis, EarlyView.
A total of 2121 used syringes were analyzed in Athens, Thessaloniki, and Patras between 2022 and 2024. Distinct drug‐use patterns were observed across the three cities. Benzodiazepines, pregabalin, methadone, and fentanyl were increasingly detected in 2024.

Piperazine neurotoxicity: worm wobble revisited.

, 1995
Piperazine has been used to treat pinworm and roundworm infections for over 40 years. Piperazine-induced cerebellar ataxia, causing the dropping of objects, clumsiness, and gait abnormalities, has been infrequently reported, usually in the setting of ...

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Synthesis and characterization of Fe(III)-piperazine-derived complexes encapsulated in zeolite Y

Química Nova, 2012
Zeolite-encapsulated complexes have been widely applied in hydrocarbon oxidation catalysis. The "ship-in-a-bottle" encapsulation of iron(III) complexes containing piperazine and piperazine-derivative ligands in zeolite-Y is described. The flexible ligand

Enhanced Electron‐Capturing by Single‐Atomic Iron on Pyridinic N‐Deficient Carbon Drives Self‐Oxidative Degradation of Pollutants

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Pyrolysis of FeOx/g‐C3N4 and ZIF‐8 is performed to introduce Fe single atom and pyridinic nitrogen vacancies onto N‐doped carbon. This modification enables the materials to efficiently extract electrons from ciprofloxacin (CIP) and activate dissolved oxygen. 100% of CIP was degraded within 1 min without adding any oxidant.
