Direct Integration of Micromachined Pipettes in a Flow Channel for Single DNA Molecule Study by Optical Tweezers [PDF]
, 2001 We have developed a micromachined flow cell consisting of a flow channel integrated with micropipettes. The flow cell is used in combination with an optical trap setup (optical tweezers) to study mechanical and structural properties of λ-DNA molecules ...

Advanced Functional Materials, EarlyView.Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Structural Behaviour of Polystyrene Foam Lightweight Concrete Beams Strengthened with FRP Laminates
International Journal of Concrete Structures and Materials, 2022 Lightweight concrete (LWC) is one of the most important building materials nowadays. Many research studies were focused on LWC produced using lightweight aggregates. However, limited work was cited for LWC produced using polystyrene beads. In this study,

The Possibility of Produce Self Compacted Polystyrene Concrete
Journal of Engineering and Sustainable Development, 2012 The aim of this study is to produce one types of self-compacted lightweight concrete which is known as self-compacted polystyrene concrete (SC-PC) . The SC-PC was produced by using expanded polystyrene beads as a partial replacement by volume of sand ...

Up and away: ontogenic transference as a pathway for aerial dispersal of microplastics [PDF]
, 2018 Microplastics (MPs) are ubiquitous pollutants found in marine, freshwater and terrestrial ecosystems. With so many MPs in aquatic systems it is inevitable that they will be ingested by aquatic organisms, and be transferred up through the food chain ...
