Scaling Description of Creep Flow in Amorphous Solids

Marko Popovic, Matthieu Wyart, Wencheng Ji, Thomas Willem Jan de Geus

Amorphous solids such as coffee foam, toothpaste, or mayonnaise display a transient creep flow when a stress E is suddenly imposed. The associated strain rate is commonly found to decay in time as gamma_ -t-nu, followed either by arrest or by a sudden flui ...

Algal cellulose, production and potential use in plastics: Challenges and opportunities

Horst Pick, Christian Ludwig, Adrian Pulgarin, Enio Daniel Zanchetta, Eya Nicodeme, Tobias Borgmeyer

The development of new biodegradable plastic materials from renewable sources is a major challenge for plastic industries to provide sustainable alternatives to petroleum plastic. Bio-based plastics are generally obtained from photosynthetic biomass such a ...

Inferring the flow properties of epithelial tissues from their geometry

Marko Popovic, Valentin Camille Druelle, Matthieu Wyart

Amorphous materials exhibit complex material properties with strongly nonlinear behaviors. Below a yield stress they behave as plastic solids, while they start to yield above a critical stress sigma(c). A key quantity controlling plasticity which is, howev ...

Detection and Quantification of Nonlabeled Polystyrene Nanoparticles Using a Fluorescent Molecular Rotor

Florian Frédéric Vincent Breider, Angélique Emmanuelle Moraz

Plastic pollution has reached alarming levels in recent years. While macro- and microplastic pollution are attested and studied since the 1970s, much less is known about the associated nanoscopic fragments. Due to their ability to cross biological barriers ...

Nature-inspired Circular-economy Recycling (NaCRe) for Proteins

Simone Giaveri

Since a few decades our planet has been loaded with billion tons of synthetic polymer-based materials, commonly named plastics. The large scale of plastic production, associated with its limited recyclability, are the driving force for the accumulation of ...

Insights into the Horizontal and Vertical Profiles of Microplastics in a River Emptying into the Sea Affected by Intensive Anthropogenic Activities in Northern China

Florian Frédéric Vincent Breider, Wenxin Liu, Yang Liu

Studies focused only on surface water may underestimate microplastic abundance in aquatic environments. This was the first survey to investigate the vertical (surface, intermediate, and bottom waters) distribution and composition of microplastics (MPs) in ...

Hybridization of Synthetic Humins with a Metal-Organic Framework for Precious Metal Recovery and Reuse

Wendy Lee Queen, Claudia Esther Avalos, Olga Trukhina, Vikram Vinayak Karve, Till Marian Schertenleib, Jordi Espin Marti

The number of synthetic strategies used to functionalize MOFs with polymers is rapidly growing; this stems from the knowledge that non-native polymeric guests can significantly boost MOF performance in a number of desirable applications. The current work p ...

Developing new tools to study and program cell fate at the single-cell level

Marjan Biocanin

Single-cell transcriptomics (scRNA-seq) started a technological revolution in biology by enabling through the plethora of methods to assess a molecular state of the cell on systems level without the strict necessity of the prior knowledge of the cell state ...

Effects of Anthropogenic Discharge and Hydraulic Deposition on the Distribution and Accumulation of Microplastics in Surface Sediments of a Typical Seagoing River: The Haihe River

Florian Frédéric Vincent Breider, Wenxin Liu, Yang Liu

Microplastics pollution in river systems has generated great concern; however, few studies have focused on the contributions of multiple influencing factors to microplastics in river systems. In the current study, we utilized data on microplastics in surfa ...

Microstructured biodegradable fibers for advanced controlled release

Shahrzad Shadman Yazdi

Biodegradable polymers are increasingly at the heart of therapeutic devices. Particularly in the form of thin and elongated fibers, they offer an effective strategy for controlled-release in a variety of biomedical configurations such as sutures, scaffolds ...

Loopy Levy flights enhance tracer diffusion in active suspensions

Andrea Cairoli, Tomohiko Sano

A theoretical framework describing the hydrodynamic interactions between a passive particle and an active medium in out-of-equilibrium systems predicts long-range Levy flights for the diffusing particle driven by the density of the active component. Browni ...
