Late‐Stage Phenylation From [13C6] and [2H5]Benzene: A Versatile Tool for Stable Isotope Labeled MS Standards

Chemistry – A European Journal, EarlyView.
ABSTRACT We explored aryl thianthrenation as a tool for directly incorporating multiple isotopes into molecular scaffolds starting from full isotopically labeled benzene. Stable isotope‐labeled (SIL) molecules are indispensable tools for investigating chemical and biological mechanisms and quantifying metabolites.

Rh‐Catalyzed [2 + 2 + 2] Cycloaddition of Linked Bis(Diynes) Ar‐C≡C‐C≡C‐(CH2)3‐C≡C‐C≡C‐Ar With Quinones: Synthesis and Photophysical Properties of Bis(Arylethynyl)‐Naphthoquinones and Anthraquinones

Chemistry – A European Journal, EarlyView.
We report the synthesis bis(arylethynyl)naphtho‐ and anthraquinones via Rh(I)‐catalyzed [2 + 2 + 2] cycloaddition reactions. The substrate scope of both quinones and linked bis‐diynes was explored. Microwave irradiation remarkably enhanced yields.

Precipitation of niobic acid from potassium niobate in sulphuric acid solution: A route to niobium oxide

The Canadian Journal of Chemical Engineering, EarlyView.
Graphical abstract illustrating the niobic acid precipitation process applied and the product obtained. Abstract This study investigates the precipitation of niobic acid (Nb2O5.nH2O) from potassium niobate solution with addition of sulphuric acid, and its subsequent thermal conversion into niobium oxide (Nb2O5). Thermodynamic modelling with PHREEQC and

Nanolignin Functional Separators for Flexible Lithium–Sulfur Batteries With Enhanced Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nanolignin‐functionalized separators, incorporating lignin nanoparticles into a crosslinked PEGDA coating applied on commercial separators, reduce polysulfide shuttling, thereby enhancing cycling performance in flexible lithium–sulfur pouch cells, while also improving thermo‐oxidative stability and flame retardancy.

The Effects of Arabic Gendered Language in Job Advertisements on Recruiters’ Evaluation of Job Applicants—A Hiring‐Simulation Experiment

European Journal of Social Psychology, EarlyView.
ABSTRACT This research investigated the impact of grammatically gendered language in Arabic job advertisements on recruiters’ evaluation of applicants’ job fit, wage allocation, and hireability. In a between‐participants hiring‐simulation experiment, Arabic‐speaking recruiters from local companies in Egypt (N = 181) evaluated either a woman or a man ...

Crossed cerebellar diaschisis in status epilepticus: A systematic review of the literature

Epileptic Disorders, EarlyView.
Abstract Objective Crossed cerebellar diaschisis is a neuroimaging phenomenon observed in various neurological conditions, including status epilepticus. This systematic review aims to summarize the clinical and radiological characteristics of patients developing crossed cerebellar diaschisis following status epilepticus and to discuss potential ...

The cervico‐vaginal DNA methylation WID‐qEC test: An epigenetic marker associated with ovarian cancer in the absence of endometrial and cervical cancer

International Journal of Cancer, EarlyView.
What's New? The DNA methylation‐based WID‐qEC test has been validated for the accurate detection of endometrial and cervical cancers using cervico‐vaginal samples. However, a small proportion of women test positive despite the absence of these cancers. This study explored the associated biological and clinical characteristics to inform potential follow‐
