Sustainable Halogen-Free Flame-Retardant Flexible Polyurethane Foams via Lignin-Waterborne Polyurethane Pickering Foam Templates

Zhenghao Shi, Qin Wang, Ernest K.W. Tsang, Jian Lin Chen et autres

This study presents a sustainable strategy to fabricate flame-retardant flexible polyurethane foam (FPUF) via a green aqueous Pickering foam templating method. Lignin was used as a biobased stabilizer and gelation agent, while 10-(2,5-dihydroxyphenyl)-10H-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO-HQ) served as a halogen-free flame-retardant and reinforcing …

Fine-tuned Ce electron density directs H2O2 activation pathway in industrially employable CeO2 nanozymes for ∼100% specificity and boosted activity in (Bromo)peroxidase mimicking

Tianqi Cheng, Bo Yuan, Chao Zhao, Zicong Tan et autres

Nanozymes are promising alternatives to natural enzymes; however, most of them lack specificity, resulting in multiple enzyme-like activities that can interfere with one another in targeted applications. For example, CeO 2 nanozymes are often reported to exhibit both peroxidase (POD)-like and bromoperoxidase …

A bioorthogonal frequency-shift SERS sensor for the ultrasensitive diagnosis of γ-glutamyl transferase activity

Yaru Gao, Qiang Guo, Jing Sun, Wanqing Dai et autres

A bioorthogonal frequency-shift SERS platform quantifies γ-glutamyl transferase. Cleavage of a butadiyne reporter on a 3D AgNP array induces a 5 cm −1 shift in the Raman silent region, enabling ultrasensitive detection (0.032 U L −1 ).

Engineering a Universal Scaffold for Activatable Near-Infrared Photosensitizers

Liu Yang, Shumei Huang, Jian Lin Chen, Peng Xiao et autres

High Resolution Image Download MS PowerPoint Slide The efficacy of photodynamic therapy (PDT) critically depends on the intrinsic properties of the employed photosensitizer (PS). Conventional PSs often suffer from an “always-on” characteristic, which leads to poor selectivity and undesirable phototoxicity in nontarget …

Yuzhen Cai, Zhanping Xiao, Tianqi Cheng, Bo Yuan et autres

Natural enzymes are efficient catalysts but face high costs and instability, leading to the development of artificial enzymes like nanozymes. While noble metals commonly demonstrate high peroxidase (POD)-like activity, their expense limits their practical use. In contrast, 3d transition metal oxides, though …
