In this work, a new n-type small molecule consisting of a fused thiophene backbone and barbituric acid as the electron-withdrawing group is reported. For green-selective organic photodiodes, when combined with p-type subphthalocyanine, the external quantum efficiency reached 64% at -3 V, owing to suitable absorption properties, efficient charge separation and relatively good transport.

In this study, we successfully fabricated a novel biocomposite composed of 6-amino β-cyclodextrin (CDNH) grafted onto magnetic chitosan (FeO@Cs). This biocomposite was thoroughly characterized using FT-IR, NMR, PXRD, EDX mapping, SEM, TEM, TGA, and VSM techniques. Subsequently, the innovative biocomposite was harnessed to serve as a heterogeneous catalyst to facilitate two series of multicomponent reactions (MCRs) aimed at synthesizing pyrazole-fused heterocycle derivatives.

The microspecies-specific physicochemical properties of eutectic solids of sparingly water-soluble micronutrient, Vitamin B (Riboflavin), with a few representative BCS drugs, viz., Theophylline, Theobromine, Mesalamine, and Barbituric acid are established. The interplay of solubility and drug permeation behavior is experimentally determined for the eutectic solids, and properties are corroborated with the concomitant relative concentrations of pH-dependent microspecies of Riboflavin and the drugs.

In this work, a Cobalt-Zinc-Copper ferrite (CoZnCuFeO, CZCF) was synthesized and functionalized with silica and guaninium tartrate ionic liquid (CoZnCuFeO-SiO@[GuaH][Tar][GuaH]). The novel bio-nanostructure was characterized by various techniques such as fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray analysis (EDAX), EDAX mapping, field emission scanning electron microscopy (FESEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), thermogravimetric/differential thermal gravimetric analysis (TGA/DTG), vibrating sample magnetometry (VSM), high resolution transmission electron microscopy (HRTEM), and zeta potential analysis. The synthesized bio-nanocomposite exhibited high catalytic activity for the aqua-mediated synthesis of polyhydroxy-substituted pyridine-dipyrimidine fused heterocycles through the one-pot pseudo four-component reaction of carbohydrates (sugars), barbituric acid, and amines under refluxing conditions.

This study presents the development of two simple, sensitive, and selective microextraction and preconcentration procedures for determining nicotinamide (NAM) in pharmaceutical formulations and blood samples. The methods utilize the König reaction, where cyanogen chloride, formed by reacting potassium thiocyanate with sodium hypochlorite in an acidic medium, interacts with NAM and couples with buffered barbituric acid at pH 3.5 to form a pink polymethine dye.
