Electroreduction of CO2 From Flue Gas: Impurity Tolerance and Mechanistic Insights in Molecular Catalysis

ChemSusChem, Volume 19, Issue 6, 27 March 2026.
Impurity‐tolerance exhibited by Re molecular complex for CO2 conversion from flue gas containing 10% CO2, 10% O2, 100 ppm NO2 and 50 ppm SO2 in N2 matrix. This tolerance is based on electrochemical reduction of gas impurities on the electrode surface under CO2 electrolysis conditions.

Induced‐Fit Recognition by a Calixarene–Pyrene Conjugate for Single‐ and Dual‐Wavelength Fluorescence Sensing in Water

Chemistry – A European Journal, Volume 32, Issue 12, 23 March 2026.
A sulfonatocalix[4]arene–pyrene conjugate functions as a fluorescence chemosensor for the optical detection of biorelevant analytes in water. Its photoinduced electron transfer (PET) response is triggered by an induced‐fit recognition mechanism. Noncovalent assembly with an additional dye affords dual‐color ratiometric signaling via competitive PET ...

Polydopamine Coating in Trabecular Bone‐Like Scaffolds With Strontium‐Substituted Nanohydroxyapatite for Bone Tissue Engineering

Journal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
PLA and strontium‐substituted hydroxyapatite filaments were used in 3D printing to fabricate a trabecular‐inspired scaffold. The scaffold was functionalized with a polydopamine coating. Characterization revealed enhanced surface properties and mechanical performance, supporting its potential application in bone tissue engineering.

Layered double hydroxides-indomethacin nanohybrids: intercalation, pH influence, stability and release properties [PDF]

, 2016
In this work, three pH values (8, 9 and 10) were studied for the insertion of Indomethacin (Indo) molecules into Layered Double Hydroxides (LDHs). The obtained results showed that the LDH materials have been a good storage for the drug.

Expanding the 2, 2’-bipyrimidine bridged 1D homonuclear coordination polymers family: [MIIbpymCl2] (M=Fe, Co) magnetic and structural characterization [PDF]

, 2013
One pot reaction of hydrated chloride salts of Fe(II) and Co(II) with stoichiometric amounts of 2,2’-bipyrimidine (bpym) in a methanol–acetonitrile mixture afforded the corresponding 1D homonuclear coordination polymers, [μ-(bpym)MCl2]n.
