Synthesis of Bimetallic (Iron–Cobalt) Single Atom Catalysts for Electrochemical Detection of Nitrites

open access: yesAdvanced Materials Technologies, EarlyView.
A CO2 laser‐assisted solid‐state synthesis of a bimetallic single‐atom catalyst is presented. The resulting material consists of a 3D porous graphene support with iron and cobalt atoms anchored as single atoms. Through electrochemical methods, the material's efficiency is demonstrated in the sensitive and selective determination of nitrite, mimicking ...

4-Cyano-3-fluorophenyl 4-(hexadecyloxy)benzoate

open access: yesActa Crystallographica Section E, 2014
In the title compound, C30H40FNO3, the dihedral angle between the benzene rings is 57.76 (7)°. The alkyl chain adopts an all-trans conformation. In the crystal, molecules are linked by pairs of C—H...O hydrogen bonds, forming inversion dimers.

Synthesis and Structures of Fused N-Heterocylic Carbenes and Their Rhodium Complexes [PDF]

open access: yes, 2010
New procedures for the synthesis of N-heterocyclic carbenes with multiple fused rings have been developed utilizing a key ring-closing metathesis step. Rhodium complexes were obtained via the pentafluorophenyl carbene adducts.

Modulating D33 Coefficients Through In Situ AgF and Ag2O Growth in PVDF Composites for High‐Performance Piezoelectric Nanogenerators

open access: yesAdvanced Materials Technologies, EarlyView.
In situ, nanoparticle doping enhances the piezoelectric coefficient (**d₃₃**) of PVDF to ≈12 pC/N, while in situ growth of AgF and Ag₂O dopants increases β‐phase concentration. The nanogenerator achieves a 35 V open‐circuit voltage and 1.6 µA short‐circuit current, powering 10 blue LEDs and charging a 50 nF capacitor within 10 s.

The crystal structure of Acinetobacter baumannii bacterioferritin reveals a heteropolymer of bacterioferritin and ferritin subunits

open access: yesScientific Reports
Iron storage proteins, e.g., vertebrate ferritin, and the ferritin-like bacterioferritin (Bfr) and bacterial ferritin (Ftn), are spherical, hollow proteins that catalyze the oxidation of Fe2+ at binuclear iron ferroxidase centers (FOC) and store the Fe3+

1,3,4-Thiadiazole-Containing Azo Dyes: Synthesis, Spectroscopic Properties and Molecular Structure

open access: yesMolecules, 2020
Three series of azo dyes derived from 2-amino-5-aryl-1,3,4-thiadiazoles and aniline, N,N-dimethylaniline and phenol were synthesized in high yields by a conventional diazotization-coupling sequence.

Serial crystallography at synchrotrons and X-ray lasers

open access: yesIUCrJ, 2017
Serial crystallography was developed for the use at free-electron lasers but the approach has recently also been adapted to synchrotron sources. Here we discuss how the synergy between the two X-ray sources will facilitate a wide application of the ...

Enhanced Two‐Photon Excited Emission of Quantum Emitters by Colloidal Plasmonic Metasurfaces

open access: yesAdvanced Photonics Research, EarlyView.
Colloidal plasmonic metasurfaces presenting a completely exposed optical cavity are fabricated via templated self‐assembling silver nanoparticles into squared arrays on top of a thin film of CdSe/ZnS quantum dots. The resulting structure promotes the enhancement of the two‐photon absorption and emission processes of the quantum emitter by exploiting ...
