A new Schiff base, (E)-2-(((1,10-phenanthrolin-5-yl)imino)methyl)-4,6-di-tert-butylphenol (Fen-IHB), was designed to incorporate an intramolecular hydrogen bond (IHB) between the phenolic OH and the azomethine nitrogen with the goal of modulating its...

This work presents new results and conclusions on nanomembrane filtration and reverse osmosis of Mavrud red wine, produced in Bulgaria. The experiments were focused on lowering the alcohol content while preserving the valuable substances in the wine....

Nanofluidic memristors are an emerging class of devices that harness ion transport in confined nanoscale environments to achieve tunable resistance states, mimicking biological synaptic functions. The regulation of ion migration, accumulation, and de...

The COVID-19 pandemic has prompted the scientific community to develop new weapons against the SARS-CoV-2 spike protein. The study of its mutations is important to understand how it interacts with human receptors and how to prevent a future pandemic....

The reaction of thiophenylsulfides with diacetoxyiodobenzene, iodine and light produced corresponding acetoxylated products, allowing the formation of new C-O bonds from starting materials other than carbonyls in high yields. Hence, under these condi...

Endophytes are important sources of bioactive secondary metabolites with therapeutic and agricultural relevance. This study reports the isolation and characterization of bioactive compounds from endophytic Fusarium solani associated with Solanum sura...

The presence of sulfate anions induces the self-assembly of anion-binding bis(cyclopeptides) in which two cyclopeptide rings are connected via a rigid linker. In this way, 2:2 complexes are formed in which two anions are sandwiched between two bis(cy...

Aluminum (Al) and zinc (Zn) are two of the most widely used metals in industry, and their excessive accumulation in the body has been linked to serious diseases like Alzheimer’s, Parkinson’s, and cancer. This highlights the need for effec...

Aromaticity and antiaromaticity are concepts that are often used to explain and predict the physical and chemical properties of cyclic conjugated compounds. They are associated with 4n + 2 and 4n cyclically arranged electrons that are delocalized and...

This study investigates the influence of vacancy engineering and nitrogen doping on the structural, electronic, and optical properties of T-graphene fragments (TFs) using density functional theory (DFT) and time-dependent DFT (TD-DFT). A central vaca...
