• Control of material crystallization by agitation
  

  The transition of unstructured amorphous materials into structured crystalline materials is generally induced by heating materials above their transition temperature. Crystalline materials are important in technology like devices, so alternative ways to control their formation has attracted much int more

• Oyster shells inspire new method to make superstrong, flexible polymers
  

  Researchers at Columbia Engineering have demonstrated for the first time a new technique that takes its inspiration from the nacre of oyster shells, a composite material that has extraordinary mechanical properties, including great strength and resilience. By changing the crystallization speed of a more

• Forces that align crystals and help them snap together measured
  

  Like two magnets being pulled toward each other, tiny crystals twist, align and slam into each other, but due to an altogether different force. For the first time, researchers have measured the force that draws them together and visualized how they swivel and align. Called van der Waals forces, the more

“Perfect Glass”

Princeton University researchers have developed a computational model for creating a "perfect glass" that never crystallizes — even at absolute zero. The molecular structure of a glass suggests it should have liquid properties, yet it behaves with the rigidity of a solid. The researchers expande ... more

Pulling Apart Titanium Oxide Surfaces

Researchers slowly pull apart tiny bits of a titanium oxide mineral called rutile. The red dots near the top show the starting point. As the bottom half is pulled down, the top half stays attached by van der Waals forces -- until, that is, the pull becomes too great. The tips are about a thousan ... more

• Automated Dynamic Light Scattering
  

  DLS analysis is a widely applied, non-invasive method for measuring the effective size of molecules in solution. This technique yields valuable information for the characterization of molecules and particles. It facilitates formerly laborious and tim more

• Measurement of Nano particles and Proteins
  

  Colloid emulsions in their native environment require particle size determination in high concentration since there are concerns about changes in sample more

• Absolute Molar Mass Characterisation
  

  Multi-angle light scattering coupled to SEC or other fractionation methods can provide an absolute means for measuring the molar mass, size and distribution of proteins, polymers and particles of all sorts. Wyatt Technology's MALS also enables the el more

The Shapes of Snowflakes

In the Northern Hemisphere at least, the idealised vision of Christmas involves snow. Whilst no one snowflake is exactly the same as another, at least on a molecular level, scientists have none-the-less devised a system of classification for the many types of crystals that snow can form. This graphi more

National Chemistry Week

In this graphic, we look at the amazing versatility of sucrose, and how (combined with other ingredients) it can make candies as hard as lollipops, or as soft as fudge. Whilst there are a huge variety of candies available, we can actually divide them into just two main categories: crystalline and no more

The Chemistry of Ice Cream

Ice cream is a mainstay of summer – for many, a trip to the beach would be incomplete without one. Despite its seeming simplicity, ice cream is a prime example of some fairly complex chemistry. This graphic takes a look at some of the ingredients that go into ice cream, and the important role they p more

• Orientation and crystallization of regioregular poly(3-dodecylthiophene) in alumina nanopores

  Orientation and crystallization of regioregular poly(3-dodecylthiophene) (P3DDT) in different diameter nanopores were investigated. P3DDT nanowires were prepared by melt-wetting nonporous alumina template with P3DDT melts. The microstructure in the nanowires were analyzed by micro-Fourier transform more

• Influence of HMW tail chains on the structure evolution of HDPE induced by second melt penetration

  It is widely accepted that the role of the high molecular weight (HMW) component is cooperative in shear-induced crystallization, owing to the entanglements among long chains. However, this paper demonstrated that the HMW component has a novel effect on the structure evolution in the process of mult more

• Subgrain boundaries in single crystal blade airfoil of aircraft engine

  The single crystal turbine blades of aircraft engine were obtained by directional solidification of Ni‐based superalloy via Bridgman technique at withdrawal rate of 5 mm/min. The CMSX‐4 industrial alloy were used for crystallization. After crystallization the blades were subjected to heat treatmen more

• The Beginning of the End?
  

  Those of us who have been either directly involved in, or on the periphery of, the pharmaceutical industry over the last decade have seen at first hand a dramatic change. Times change, and technology changes. Take computer data storage for example. Not so long ago, the floppy disk was state of the art, replaced by the CD-ROM, and then by the USB drive. more
