Sci Total Environ 2021 May 27;791:148060. Epub 2021 May 27.

Scripps Institution of Oceanography, University of California San Diego, La Jolla, CA 92093, USA. Electronic address:

As global production of textiles rapidly grows, there is urgency to understand the persistence of fabrics in the marine environment, particularly from the microfibers they shed during wearing and washing. Here, we show that fabrics containing polyester (one of the most common plastics) remained relatively intact (viz., with a limited biofilm) after >200 days in seawater off the Scripps Oceanography pier (La Jolla, CA), in contrast to wood-based cellulose fabrics that fell apart within 30 days.

Formation of Fiber Fragments during Abrasion of Polyester Textiles.

Environ Sci Technol 2021 06 1;55(12):8001-8009. Epub 2021 Jun 1.

Technology and Society Laboratory, Empa - Swiss Federal Laboratories for Materials Science and Technology, Lerchenfeldstrasse 5, St. Gallen 9014, Switzerland.

Fiber fragments are one of the dominant types of microplastics in environmental samples, suggesting that synthetic textiles are a potential source of microplastics to the environment. Whereas the release of microplastics during washing of textiles is already well studied, much less is known about the release during abrasion processes. The abrasion of textiles may induce fibrillation of fibers and therefore result in the formation of much finer fiber fragments. Read More

Microplastic fibers influence Ag toxicity and bioaccumulation in Eisenia andrei but not in Enchytraeus crypticus.

Ecotoxicology 2021 Aug 27;30(6):1216-1226. Epub 2021 May 27.

Department of Ecological Science, Faculty of Science, Vrije Universiteit, Amsterdam, The Netherlands.

Microplastic fibers (MF) are released from synthetic textiles during washing and end up in the wastewater. Similarly, silver nanoparticles (AgNP), incorporated in textiles as antimicrobial agents, are released in washing machines, also reaching the wastewater treatment plants. Therefore, both MF and AgNP co-exist in the environment and enter the soil compartment mainly via the application of biosolids. Read More

Preparation of conductive cellulose fabrics with durable antibacterial properties and their application in wearable electrodes.

Int J Biol Macromol 2021 Jul 3;183:651-659. Epub 2021 May 3.

School of Light Industry and Engineering, South China University of Technology, Guangzhou 510640, China. Electronic address:

Electroless silver plating on fabrics can obtain conductive and antibacterial bifunctional materials which can be used as electrodes in wearable electronic products. However, these activities are deteriorated easily after washing because of the falling off of silver coating resulted from the weak adhesion. In order to improve the binding force between silver and cellulose fabrics, 3-mercaptopropytrimethoxysilane (MPTS) was applied to modify cellulose fabrics before silver electroless plating to develop the durable conductive fabrics with excellent antibacterial.

Digging roots is easier with AI.

J Exp Bot 2021 Jun;72(13):4680-4690

Department of Organic Farming and Cropping Systems, University of Kassel, Nordbahnhofstr. 1a, 37213 Witzenhausen, Germany.

The scale of root quantification in research is often limited by the time required for sampling, measurement, and processing samples. Recent developments in convolutional neural networks (CNNs) have made faster and more accurate plant image analysis possible, which may significantly reduce the time required for root measurement, but challenges remain in making these methods accessible to researchers without an in-depth knowledge of machine learning. We analyzed root images acquired from three destructive root samplings using the RootPainter CNN software that features an interface for corrective annotation for easier use. Read More

Org Biomol Chem 2021 03 10;19(12):2773-2783. Epub 2021 Mar 10.

Department of Biocatalysis, Institute of Catalysis (ICP-CSIC), Marie Curie 2, 28049 Madrid, Spain.

Different Pd-complexes containing orthometallated push-pull oxazolones were inserted by supramolecular Pd-amino acid coordination on two genetically engineered modified variants of the thermoalkalophilic Geobacillus thermocatenolatus lipase (GTL). Pd-lipase conjugation was performed on the solid phase in the previously immobilized form of GTL under mild conditions, and soluble conjugated Pd-GTL complexes were obtained by simply desorbing by washing with an acetonitrile aqueous solution. Three different Pd complexes were incorporated into two different genetically modified enzyme variants, one containing all the natural cysteine residues changed to serine residues, and another variant including an additional Cys mutation directly in the catalytic serine (Ser114Cys).
