The Role of Polarizability in Isoelectronic Ions: The Case of Pseudohalides.

Specific ion effects are widespread and have been studied for over a century, yet they remain poorly understood. Terms like "kosmotropes" and "chaotropes" are convenient rules of thumb but the frequent reversal of the Hofmeister series implies their limitations. Polarizability is often used to classify ions, with kosmotropes considered low in polarizability and chaotropes high.

Preparation and Characterization of the MMT@FeO@Ag Nanocomposite for Catalytic Degradation of Methyl Yellow: Reaction Parameters and Mechanism Based on the Artificial Neuron Network.

The montmorillonite@iron oxide@silver (MMT@FeO@Ag) nanocomposite, which is recyclable and exhibits high catalytic activity, was evaluated for the degradation of methyl yellow (MY), a carcinogenic azo dye. For this purpose, MMT@FeO was first synthesized via the coprecipitation method and then Ag was doped to MMT@FeO via the chemical reduction method. MMT, MMT@FeO, and MMT@FeO@Ag were characterized by various techniques including scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, vibrating sample magnetometer, and thermal gravimetric analysis.

Radio-Anatomical Assessment of Cerebellum Volume in Individuals with Alzheimer's Disease.

Introduction: Alzheimer's disease is a chronic brain disease that includes memory and language disorders. This disease, which is considered the most common cause of dementia worldwide, accounts for 60-80% of all dementia cases. Recent studies suggest that the cerebellum may play a role in cognitive functions as well as motor functions.

Curious effects of overlooked aspects on urease activity.

Intermolecular forces determine complex chemical structures of exquisite intricacy, like proteins. However even the most advanced theories we have so far rely on too drastic approximations to explain them. Some crucial aspects that dictate structure, specific ion and solvent effects are not accommodated.
