A deep learning based model for diabetic retinopathy grading.

Diabetic retinopathy stands as a leading cause of blindness among people. Manual examination of DR images is labor-intensive and prone to error. Existing methods to detect this disease often rely on handcrafted features which limit the adaptability and classification accuracy.

MOF UiO-66 and its composites: design strategies and applications in drug and antibiotic removal.

Antibiotics and pharmaceuticals exert significant environmental risks to aquatic ecosystems and human health. Many effective remedies to this problem have been developed through research. Metal-organic frameworks (MOFs) are potential constituents, for drug and antibiotic removal.

From pollutant to purifier: Leveraging plastic waste-derived activated carbon for sustainable water remediation solutions.

The ubiquitous presence of plastic waste presents a significant environmental challenge, characterized by its persistence and detrimental impacts on ecosystems. The valorization of plastic waste through conversion into high-value carbon materials offers a promising circular economy approach. This review critically examines the potential of plastic waste-derived activated carbon (PAC) as a sustainable and effective adsorbent for water remediation.

Heteroatom sulfur-doping in single-atom FeNC catalysts for durable oxygen reduction performance in zinc-air batteries.

Heteroatom doping into the transition metal-based catalysts is an effective strategy to improve the oxygen reduction reaction (ORR) kinetics. Herein, we proposed a one-step, soft template assisted, and green method for the synthesis of Sulfur (S) doped single atom FeNC catalyst. XAFS demonstrated that the Fe active sites in the FeNSC were more likely to possess the Fe-N configuration.

Phenylboronic acid functionalized magnetic ferroferric oxide nanoparticles and capillary electrophoresis for efficient isolation of flavonoid compounds from leaves of Lonicera japonica Thunb.

Flavonoids are bioactive components in natural products, which possess anti-inflammatory, antibacterial, antioxidant, and cardiovascular protective properties. However, due to the complexity and low content of the components in these samples, developing rapid and sensitive methods for the isolation and extraction of flavonoids still remains a challenge in medical and food science. Herein, a 4-formylphenylboronic acid functionalized magnetic FeO nanomaterial (FeO@FPBA) was synthesized and applied as a sorbent of magnetic solid-phase extraction (MSPE) to covalently extract flavonoids from leaves of Lonicera japonica Thunb.
