• Man versus (synthesis) machine
  

  Who is the better experimentalist, a human or a robot? When it comes to exploring synthetic and crystallization conditions for inorganic gigantic molecules, actively learning machines are clearly ahead, as demonstrated by British Scientists in an experiment with polyoxometalates. Polyoxometalates fo more

• 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

“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

• 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

• 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

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

• Co-crystallization of 1,3,5-trifluoro-2,4,6-triiodobenzene (1,3,5-TFTIB) with a variety of Lewis bases through halogen-bonding interactions

  Halogen bond is emerging as an important driving force for supramolecular self-assembly, and has attracted great interest in the last decade. Among the ample halogen-bonding donors, we note the ability of 1,3,5-triiodotrifluorobenzene1,3,5-trifluoro-2,4,6-triiodobenzene (1,3,5-TITFB1,3,5-TFTIB) to c more

• Improvements in mechanical strength and thermal stability of injection and compression molded components based on Poly Lactic Acids

  Abstract Degradable polymers are limited by their often‐insufficient mechanical and thermal properties, which limit their usage to single‐use packaging items at room temperature and in dry conditions. In this respect, the present work deals with the manufacture of custom‐built Poly Lactic Acids more

• Crystallization and Dissolution in Multicomponent Water–Salt Systems

  Phase equilibria in three quinary systems of Li, Na, K, Sr//Cl–H2O at 25 °C, Li, Na, K//SO4, B4O7–H2O at 0 °C, and Na, K, Mg//SO4, B4O7–H2O at 15 °C were investigated by means of translation method. The quinary invariant points, monovariant curves, divariant fields, and trivariant volumes which are 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
