Transforming waste particles into valuable adsorbents via amyloid-mediated molecular engineering

Science China Chemistry 2025年第1期68卷 317-328页

The high-value utilization of industrial solid waste using a facile and eco-friendly process is of great interest and significance in reducing environmental pollution and developing a green circular economy. Herein, we propose an amyloid-mediated molecular engineering strategy to transform particulate waste into valuable adsorbents for metal ions. Our method has the advantage of aqueous solution fabrication under mild conditions without the use of high-temperature hydrothermal methods and toxic chemical reagents. Amyloid-mediated molecular engineering manipulates the phase transition of bovine serum albumin(BSA)on particulate waste surfaces, resulting in a remarkable ～3.1 times improvement in the adsorption capacity of fly ash, a typical industrial solid waste for gold ions after modification with the phase-transitioned BSA(PTB). The resultant adsorption ability was 69–1,980 times higher than those of conventional and emerging adsorbent materials such as ion exchange resins, activated carbon(AC), covalent organic frameworks(COFs), and metal-organic frameworks(MOFs). We further demonstrated the application of our PTB-modified materials in the recovery of precious metals from low-grade gold ore and electronic waste leachates. Consequently, this strategy could increase the value of waste materials nearly 27 times. In addition, this method is generally extendable to other conventional industrial adsorbents such as resin, clay, and Al2O3, and enhances their adsorption capabilities at least twofold. Overall, this work provides a simple and green approach for improving the adsorption performance of solid particles, and is expected to develop into a universal strategy for transforming waste particles into high-value-added products.

Objective During 2003-2005, an outbreak of meningitis due to Neisseria meningitidis serogroup C occurred in China. With the aim to find strain clues result in the final epidemics, the ancestral strain 053442, a clinical isolate, and a carrier strain 053426 with different gene type were analyzed. Methods Clinical strain 053442 and carrier strain 053426 were cultured on GC agar plates under the same condition. Two-dimensional electrophoresis was performed using the pH 3–10 nonlinear IPG strips of 24 cm length, and all the protein spots were identified by matrix-assisted laser desorption/ionization time of flight spectrometry. Results 502 and 380 protein spots were identified in 053426 and 053442 respectively, relating to 266 and 202 different genes covering a wide range of cellular functions. The express volume and number of proteins involved in energy metabolism, protein synthesis and amino acid biosynthesis in 053426 were higher than in 053442. Virulence factor Opa, Opc and a series of proteins involved in pilus assembly and retraction were identified in 053442, which appear to be of primary importance in colonization and invasion of human cells. Compared to 053442, virulence protein species were less in 053426, with lower express volumes too. No Opa and Opc were detected in 053426. Conclusion The different protein expression profiles of the clinical strain 053442 and carrier strain 053426 in the present study provide some clues of the different pathogenicity of the two strains, which may account for result in the final epidemics.

Introduction Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare,aggressive,and deadly hematologic malignancy derived from the precursor of plasmacytoid dendritic cells (pDCs).1 BPDCN is a newly described type of tumor that affects hematopoietic and lymphoid tissues;it was categorized by the World Health Organization (WHO) in 2008 as the 'acute mydoid leukemia (AML) and related precursor neoplasms' group.2 This cancer can occur at any age,but most patients happen to be older adults.

The kinetics of low level chemiluminescence from Chinese white polpar leaf smoked by CO and two gaseous mixture of SO 2 and CO or SO 2, NO x and CO, and their luminescence intensity formula were described. The comparison of the results indicated that three kinds of the gaseous compounds could cause no changes of the substantial nature of foliar biophoton emission. However, they made the luminescence intensity, including I o (1) and I o (2) , altered in a certain degree, and the changes caused by the fumigation of CO and the mixed gas of SO 2 and CO were different from that made by the gaseous mixture of SO 2, NO x and CO in τ′ and τ″ of the photo induced luminescence from plant leaf.
