Diamond is composed solely of carbon. It gets its strength from having 4 bonds to every other carbon except the ones on the edges.

Molecular Models-Not Just for Chemistry

Molecular models are a staple for teaching organic chemistry to students from high school to university and beyond. For others, they are considered an anachronism in today’s world of computing, especially with advances in virtual reality. While there is some truth to these viewpoints, physical models still have many other practical uses. Below we will describe four different uses.

Lattice Structure Molecular Models

Crystal lattices are everywhere. The most familiar are diamond, ice and silicon based computer chips. There are thousands of different crystal types on Earth and their complexity and importance rival that of many organic compounds.

Alloys of titanium and gold are already used as biocompatible materials in articificial hip joints and the like. A new one was reported recently, Ti3Au (beta titanium gold),  which is 4 times stronger than other known alloys.1

The increased strength is due in part shorter interatomic bonds . This might not be immediately apparent even if pictures of the different alloys were shown side by side. In the image below, however, you can see that the bonds appeared strained but this illustrates the shorter distances and hence higher density.

Beta-Titanium-Gold
Notice the slight bending in the bonds (blue). This indicates shorter interatomic distances which in turn produces much greater hardness in alloy.

Photography Cropping Molecular Model Tool

Digital cameras are everywhere bringing out the wannabee photographer in all of us. Composition, the relative position of things in pictures, is still important, especially for product presentation. Most of us lack formal training in this but reshooting scenes are very cheap. Still, getting it right on the first few tries is important if time & money are at stake.

We created a very simple tool using molecular model parts. It consists of 4 octahedral atoms and lengths of bonds cut to length. We use one that has a 4:3 length to width ratio, the standard for most computer monitors, to frame product shots. Others such as 16:9 for high definition television can also be built.

Molecular Model Trophies

The picture below speaks for itself. We supplied molecular models of a drug called galeterone to a company which mounted them in display cases. These were handed out at an event celebrating a successful IPO (on Wall Street we  believe).

Galeterone Structure Model
Galeterone was recently announced as a new drug for the treatment of prostate cancer. The model structure itself  is roughly 375mm (15″) long.

Organizational Theory Molecular Models

Customers ranging from bankers to military have approached us asking how they could display the interconnections found in different hierarchies. In other words, who reports to whom. Relationships can be 1:1 or many to one that represent many command and reporting structures. Molecular models are inexpensive and easy to configure as can be seen in the image below.

Interestingly, the most flexible way to show such organizational patterns is with the same model style as shown in the top picture. The Unit style of models, designed for crystal structures, allows for many more connections than any other model design.
