New biologically derived metal-organic framework mimics DNA

10-Apr-2019

The field of materials science has become abuzz with "metal-organic frameworks" (MOFs), versatile compounds made up of metal ions connected to organic ligands, thus forming one-, two-, or three-dimensional structures. There is now an ever-growing list of applications for MOF, including separating ...

Chirality in 'real-time'

Circular dichroism in the deep ultraviolet

11-Jan-2019

In nature, certain molecules with the same chemical composition, can exist in two different shapes that are mirrors images of each other, much like our hands. This property is known as "chirality" and molecules with different chirality are called enantiomers. Enantiomers can exhibit entirely ...

Proteins for Making Tough Rubber

Biomimetic strategy leads to strong, recyclable rubber

12-Dec-2018

Inspired by nature, Chinese scientists have produced a synthetic analogue to vulcanized natural rubber. Their material is just as tough and durable as the original. In the journal Angewandte Chemie, they reveal the secret to their success: short protein chains attached to the side-chains of the ...

Measuring the Nanoworld

Researchers establish a benchmark for accurate determination of internal dimensions within individual molecules

05-Sep-2018

A worldwide study involving 20 laboratories has established and standardized a method to measure exact distances within individual biomolecules, down to the scale of one millionth of the width of a human hair. The new method represents a major improvement of a technology called single-molecule ...

Silk fibers could be high-tech 'natural metamaterials'

05-Feb-2018

New research has demonstrated how the nano-architecture of a silkworm's fiber causes "Anderson localization of light," a discovery that could lead to various innovations and a better understanding of light transport and heat transfer. The discovery also could help create synthetic materials and ...

A New Step towards "Computational Experiments"

Scientists develop the most advanced computer model to-date of the scattering of polarized light from chiral molecules

07-Oct-2011

An international research team has described the first calculations of Raman optical activity (ROA) spectra using coupled-cluster theory – one of the most reliable quantum chemical methods available. ROA is a valuable tool for the structural characterization of a wide range of molecules, ...
