Biofilm Engineering for Efficient Substrate-Enzyme Interactions to Enhance Enzymatic PET Degradation
1 Introduction The widespread use of plastics has created pressing environmental issues, as end-of-life plastics often accumulate in landfills or natural habitats and fragment into hazardous micro- and nanoplastics (MNPs) over time (Moon et al. 2024). Poly(ethylene terephthalate) (PET) is among the most abundantly produced synthetic polymers, with an estimated 1 million PET bottles being produced every minute (Laville and Taylor 2017; Rochman 2018).
Coupled sea-level and biodiversity dynamics during the Cambrian SPICE event
Abstract The prominent Cambrian Steptoean Positive Carbon Isotope Excursion (SPICE) stands as one of Earth’s largest carbon cycle perturbations, marked by widespread marine anoxia, climatic upheaval, and biotic turnover, yet the complete extent and interplay of these environmental changes remain unclear.
Microbial synthesis and degradation of bio-based biodegradable plastics
Abstract Microorganisms facilitate both the synthesis and breakdown of bio-based biodegradable plastics, which positions them as central players in the development of a future circular plastics economy. However, advances in microbial production and biodegradation of plastics are often considered in isolation, limiting our ability to integrate these processes into viable circular systems.

Correction to: Nature Communications https://doi.org/10.1038/s41467-025-63896-z, published online 02 October 2025 In Fig. 1 of the original Article, the stage boundaries in the left-hand Epoch/Age (Stage) panel were incorrectly segmented during redrafting. The geological time axis (360–250 Ma) and all accompanying panels and datasets are unaffected. Figure 1 has now been replaced with a corrected version.
Dynamic shift of internal electric field accelerates enzymatic polyethylene terephthalate depolymerization - Communications Chemistry
Abstract Enzymatic recycling of polyethylene terephthalate (PET) has been recognized as an eco-friendly option for addressing the global plastic waste problem. Fully deciphering the catalytic mechanism is vital for designing high-performance enzymes. Here, we performed quantum mechanics/molecular mechanics molecular dynamics simulations to systematically explore the depolymerization mechanism of PET by the hydrolase LCCICCG.

Process insights for harnessing biotechnology for plastic depolymerization - Nature Chemical Engineering
Abstract Plastics (synthetic polymers) play an essential role in modern living, but their uncontrolled disposal has led to severe environmental impacts. The production of plastics is based on fossil feedstocks, which are associated with detrimental climate effects. Thus, sustainable concepts for the re- and upcycling of plastic waste are urgently required. Biotechnological approaches have recently emerged as innovative alternatives to conventional methods.

A Query-Based Network for Rural Homestead Extraction from VHR Remote Sensing Images
Abstract : It is very significant for rural planning to accurately count the number and area of rural homesteads by means of automation. The development of deep learning makes it possible to achieve this goal. At present, many effective works have been conducted to extract building objects from VHR images using semantic segmentation technology, but they do not extract instance objects and do not work for densely distributed and overlapping rural homesteads.

Urethanases for the Enzymatic Hydrolysis of Low Molecular Weight Carbamates and the Recycling of Polyurethanes
Plastics are indispensable for beverage and food packaging, electrical insulation, construction, textiles, and medical items like masks.1 Unfortunately, the ease of mass manufacturing and resistance to degradation, two major advantages of plastic, have resulted in the environmental catastrophe of plastic pollution.2 While we may get rid of plastic waste by incineration, this would release vast amounts of CO2 and other toxic gases into the atmosphere.

Biocatalysis in the Recycling Landscape for Synthetic Polymers and Plastics towards Circular Textiles
Abstract Although recovery of fibers from used textiles with retained material quality is desired, separation of individual components from polymer blends used in today's complex textile materials is currently not available at viable scale. Biotechnology could provide a solution to this pressing problem by enabling selective depolymerization of recyclable fibers of natural and synthetic origin, to isolate constituents or even recover monomers.

Applicability Analysis of Assessment Methods for Morphological Parameters of Corroded Steel Bars
Figure 6A and 6B show that the measured diameters of the non-corroded bar specimen do not vary significantly along its length. The maximum difference between the measured diameters along the bar length is only about 0.11 mm with a maximum deviation of 0.7%. This indicates that the geometry of a non-corroded bar can be well evaluated using a Vernier caliper. However, the measured diameters at different angles of the same cross-section differ consistently and considerably from each other.

A radial calibration window for analytical ultracentrifugation
Analytical ultracentrifugation (AUC) is a first-principles based method for studying macromolecules and particles in solution by monitoring the evolution of their radial concentration distribution as a function of time in the presence of a high centrifugal field. In sedimentation velocity experiments, hydrodynamic properties relating to size, shape, density, and solvation of particles can be measured, at a high hydrodynamic resolution, on polydisperse samples.

Recent studies have shown that low hemoglobin (Hb) level promote the progression of chronic kidney disease. This study assessed the relationship between Hb level and type 1 diabetic nephropathy (DN) in Anhui Han's patients. There were a total of 236 patients diagnosed with type 1 diabetes mellitus and (T1DM) seen between January 2014 and December 2016 in our centre. Hemoglobin levels in patients with DN were compared with those without DN.
