Selective removal of uranyl ions using ion-imprinted amino-phenolic functionalized chitosan
In this study, uranyl (UO22+) ions were imprinted on an amino-phenolic chitosan derivative using an ion-imprinting method. First, 3-hydroxy-4-nitrobenzoic acid (HNB) units were joined to chitosan via amide bonding, followed by reducing the -NO2 residues into -NH2. The amino-phenolic chitosan polymer ligand (APCS) was coordinated with UO22+ ions, then cross-linked with epichlorohydrin (ECH), and finally the UO22+ ions were taken away. When compared to non-imprinted sorbent, the resulting UO22+ imprinted sorbent material (U-APCS) recognized the target ions preferentially, allowing for much higher adsorption capacities (qm = ...

Uniportal < em > vs. < /em > multiportal thoracoscopic segmentectomy: a north American study
CONCLUSIONS: Our experience from two North American centers indicates that, in experienced hands, postoperative outcomes after uniportal and multiportal VATS segmentectomy are comparable.PMID:36910108 | PMC:PMC9992592 | DOI:10.21037/jtd-22-780 (Source: Journal of Thoracic Disease)
