Photocatalytic Degradation of Paracetamol in Aqueous Medium Using TiO2 Prepared by the Sol–Gel Method

open access: yesMolecules, 2022
Two titania photocatalysts have been prepared using the sol–gel method using TiCl4 as a precursor, and two different alcohols, namely, ethanol or propanol (Et or Pr).

Reversible I2 Uptake Induces Record‐High Spin‐Crossover Hysteresis in a Fe(II) Hofmann‐Type MOF

open access: yesChemistry – A European Journal, EarlyView.
Reversible iodine uptake in a flexible Fe(II) Hofmann‐type MOF [Fe(pz)Pd(CN)4] induces record‐wide SCO hysteresis. Gas‐phase I2 acts as internal chemical pressure, stabilizing both high‐spin and LS states without altering the framework, providing a general strategy for tunable bistability in coordination networks.

Vibrational assignments of two polymorphic forms of metaxolone by using DFT calculations and the SQM methodology [PDF]

open access: yes, 2018
A theoretical study has been performed on the musclerelaxant 5-[(3, 5-dimethylphenoxy)methyl]-1,3-oxazolidin-2-one, of generic name metaxolone (MTX), by using the hybridB3LYP/6-31G calculations in the gas phase and theexperimental available infrared and ...

Ground‐ and Excited‐State Mixed Valency in a 4,4′‐Bipyridine‐Bridged Bimetallic Di‐Ruthenium Complex

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Photoinduced mixed‐valence interactions across a 4,4′‐bpy bridge were studied. MLCT excited states in the bimetallic complex are longer‐lived than in the monometallic reference, thanks to metal–metal electronic coupling and hole delocalization, but are still shorter than the nanosecond timescale relevant for diffusional reactivity.

Unprecedented layered coordination polymers of dithiolene group 10 metals: Magnetic and electrical properties [PDF]

open access: yes, 2016
One-pot reactions between Ni(ii), Pd(ii) or Pt(ii) salts and 3,6-dichloro-1,2-benzenedithiol (HSC6H2Cl2SH) in KOH medium under argon lead to a series of bis-dithiolene coordination polymers.

Biofertilization of canola seeds with Peribacillus simplex and Paenibacillus polymyxa bacteria increases tocopherol content

open access: yesJSFA reports, EarlyView.
Abstract Background Biofertilization with plant growth‐promoting bacteria (PGPB) is a reliable strategy to reduce the amounts of chemical fertilizers applied to crops. Nevertheless, the effects of biofertilizers on plant chemical constituents that influence food quality and human health should be evaluated.

Smart NIR‐Emitting Organometallo Pt(II)‐Ionosilica Aerogel for Selective Au(III) Sensing and Recovery

open access: yesSmall, EarlyView.
This study reports a near‐infrared emitting ionic aerogel composed of cationic cyclometalated Pt(II) moieties linked by Si─O─Si bonds. The resulting porous hybrid material enables the selective detection and recovery of Au(III) ions from mixed‐metal solutions. Owing to its reversible luminescent response and thiourea‐assisted gold recovery, the aerogel

Metal‐Free Electrophilic Borylative Cyclizations of Alkynes

open access: yesThe Chemical Record, EarlyView.
Metal‐free borylative cyclizations based on electrophilic alkyne activation by boron Lewis acids provide efficient access to borylated hetero‐ and carbocycles. Early studies using B(C6F5)3 displayed limited scope and application, whereas recent ClBcat‐ and BCl3‐based methods enable mild CB and CC/CX bond formation for the synthesis of cycles ...
