How to push a single-molecule switch

How to push a single-molecule switch

Chemistry

By DIPC

Everybody knows the force that is required to activate a light switch on a wall – a finger is enough. But how much force do you need to apply if the device was dramatically reduced to the “nanoscale world”, that is, how much force do you need to operate a “single-molecule switch”? This fundamental question […]

In order to study new solid state magnetic properties appropiate new laboratory models are needed. In particular, there is a necessity for a substrate to investigate new forms of magnetic coupling with nanoscale ferromagnets and the exotic physics at the interface with semiconductor or superconductor materials. Now a team of researchers from DIPC and some […]

A phase may be defined as a homogeneous portion of a system that has uniform physical and chemical characteristics. Every pure material is considered to be a phase; so also is every solid, liquid, and gaseous solution. For example, a sugar–water syrup solution is one phase, and solid sugar is another. Each has different physical […]

Ionization is a fundamental process in chemistry and physics, lying at the heart of many fascinating phenomena. Ionization is the process of producing ions. Certain molecules ionize in solution, for example. But ions may also be formed when an atom or molecule loses one or more electrons as a result of energy gained in a […]

A visionary perspective of molecular electronics is the use of single molecules as functional entities in electronic devices. In this context, some of the most important components are molecular switches, which are molecules that can be interconverted reversibly between at least two stable states, one for the OFF and one for the ON. In order […]

Dealing with fire in microgravity

Dealing with fire in microgravity

ChemistryPhysics

By Silvia Román

All we know about fire under Earth´s gravity must be questioned in microgravity. In fact, most of the well-known characteristics of fire behavior are driven by the effects of gravity. That´s why the science of combustion in low-gravity environments is an important field of knowledge for NASA studies when evaluating spacecraft safety. And, contrary to […]

All-metal aromatic compounds

ChemistryCondensed matter

By DIPC

In the early days of organic chemistry, the word aromatic was used to describe fragrant substances such as benzene (from coal distillate), benzaldehyde (from cherries, peaches, and almonds), and toluene (from tolu balsam). It was soon realized, however, that substances classed as aromatic differed from most other organic compounds in their chemical behaviour. Today, the […]
