Article Abstract
A novel Co@CaTiO₃ heterogeneous catalyst was synthesized via the sol-gel method, incorporating cobalt nanoparticles into a perovskite framework. The catalyst exhibited exceptional efficiency in the aqueous-phase synthesis of 1,2,3-triazoles through azide-alkyne cycloaddition (click reaction). Key reaction parameters, including catalyst loading, temperature, time, and solvent, were systematically optimized to achieve high yields. Comprehensive characterization using Fourier-Transform Infrared Spectroscopy (FT-IR), X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Energy Dispersive X-Ray Spectroscopy (EDX), Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Brunauer-Emmett-Teller (BET) surface area analysis, and X-ray Photoelectron Spectroscopy (XPS) revealed its high surface area, thermal stability, and uniform distribution of cobalt nanoparticles. The Co@CaTiO catalyst demonstrated remarkable reusability, easy separation, and sustainable performance, positioning it as a promising candidate for green and efficient organic transformations in aqueous media.

A novel phthalonitrile derivative (a) containing three functional groups (hexyl, aminated ester, phenoxy) was synthesized and subsequently cyclotetramerized in the presence of the corresponding metal chloride salts to obtain hexadeca-substituted metal {M = Cu(II) and Co(II)} phthalocyanines (b and c). The water-soluble phthalocyanines (d and e) were prepared by treating the newly synthesized complexes (b and c) with methyl iodide. Moreover, gold nanoparticles (1) and silver nanoparticles (2) were prepared, and their surfaces were modified with quaternary phthalocyanines (d and e).

Harnessing the significant buildup of lactic acid (LA) within the tumor microenvironment (TME) for metabolic manipulation presents a promising avenue for cancer treatment. Nevertheless, single-agent therapies often fail to address the complex and varying needs of TME heterogeneity, posing a substantial scientific hurdle in oncology. In this context, we employ asymmetric mesoporous silica nanoparticles (AMS NPs) as delivery vehicles, simultaneously loading them with zinc‑cobalt‑manganese ferrite nanoparticles (ZCMF NPs), lactate oxidase (LOX), and doxorubicin (DOX).

Wearable sensors integrated with deep learning techniques have the potential to revolutionize seamless human-machine interfaces for real-time health monitoring, clinical diagnosis, and robotic applications. Nevertheless, it remains a critical challenge to simultaneously achieve desirable mechanical and electrical performance along with biocompatibility, adhesion, self-healing, and environmental robustness with excellent sensing metrics. Herein, we report a multifunctional, anti-freezing, self-adhesive, and self-healable organogel pressure sensor composed of cobalt nanoparticle encapsulated nitrogen-doped carbon nanotubes (CoN CNT) embedded in a polyvinyl alcohol-gelatin (PVA/GLE) matrix.

The development of efficient and economical oxygen evolution reaction (OER) catalysts is highly desired, and cobalt-based nanomaterials are promising candidates. In this work, we tackle one key question for cobalt-assisted photocatalytic OER: What is the true active species of Co(OH) for the photocatalytic OER? Hence, we investigated photocatalytic OER on nanostructured Co(OH) and CoO for comparison. We found that there was a significant transformation of Co(OH) during the photocatalytic process with a [Ru(bpy)]/SO buffer.

A novel molecularly imprinted polymer (MIP)-based electrochemical sensor has been developed for the selective detection of naringenin (NAR) in various real-world samples, including plant extracts, wine, and herbal supplements. To enhance the active surface area and porosity of the glassy carbon electrode (GCE), a 2D/0D nanocomposite composed of graphene oxide (GO) and cobalt ferrite (CFO) nanoparticles, CFO_GO, was incorporated into the sensor design. 4-aminobenzoic acid (4-ABA) was selected as the functional monomer to prepare the MIPs.
