Mussel research strenghtens graphene

Polydopamine acts as binder to achieve high mechanical and electrical properties

24-Oct-2018

Researchers demonstrated the mussel-inspired reinforcement of graphene fibers for the improvement of different material properties. A research group under Professor Sang Ouk Kim applied polydopamine as an effective infiltrate binder to achieve high mechanical and electrical properties for ...

Bacteria "brewing" tiny, high-energy carbon rings

10-Apr-2018

Caltech scientists have created a strain of bacteria that can make small but energy-packed carbon rings that are useful starting materials for creating other chemicals and materials. These rings, which are otherwise particularly difficult to prepare, now can be "brewed" in much the same way as ...

3-D printing improves cell adhesion and strength of PDMS polymer

25-Jan-2018

Combining two different polymer forms can switch manufacturing of silicone parts from molding, casting and spin coating of simple forms to 3-D printing of complex geometries with better mechanical characteristics and better biological adhesion, according to a team of Penn State researchers. "So ...

New insights into underwater adhesives

18-Jan-2018

A Korean research team, affiliated with UNIST has presented a new type of underwater adhesives that are tougher than the natural biological glues that mussels normally use to adhere to rocks, ships, and larger sea critters. This has attracted much attention as a technology that surpass the limits ...

Engineers stop soap bubbles from swirling

15-Sep-2016

The spinning rainbow surface of a soap bubble is more than mesmerizing - it's a lesson in fluid mechanics. Better understanding of these hypnotic flows could bring improvements in many areas, from longer lasting beer foam to life-saving lung treatments. The whirling on the surface of bubbles is ...

Learning from the mussel, scientists create a biologically active titanium surface

11-Jul-2016

Titanium is used medically in applications such as artificial joints and dental implants. While it is strong and is not harmful to tissues, the metal lacks some of the beneficial biological properties of natural tissues such as bones and natural teeth. Now, based on insights from mussels--which ...

From super to ultra-resolution microscopy

07-Jul-2016

Proteins mostly do not work in isolation but rather make up larger complexes like the molecular machines that enable cells to communicate with each other, move cargo around in their interiors or replicate their DNA. Our ability to observe and track each individual protein within these machines is ...

First single-enzyme method to produce quantum dots revealed

11-May-2016

Quantum dots (QDs) are semiconducting nanocrystals prized for their optical and electronic properties. The brilliant, pure colors produced by QDs when stimulated with ultraviolet light are ideal for use in flat screen displays, medical imaging devices, solar panels and LEDs. One obstacle to mass ...

Tiny microbots that can clean up water

Self-propelled tiny ‘microbots’ that can remove pollution from contaminated water developed.

03-May-2016

Working with colleagues in Barcelona and Singapore, Samuel Sánchez’s group used graphene oxide to make their microscale motors, which are able to adsorb lead from industrial wastewater from a level of 1000 parts-per-billion to down to below 50 parts-per-billion in just an hour. The lead can ...

Micromotors use surface variations for docking and guiding

18-Feb-2016

Researchers at the Max Planck Institute for Intelligent Systems, the Institute for Bioengineering of Catalonia (IBEC) and the University of Stuttgart have revealed in an article in Nature Communications that micromotors can be guided using tiny topographical patterns on the surfaces over which ...
