Molecular switch detects metals in the environment

Chemical sensor capable of detecting the presence of metals

17-Aug-2018

An international team, led by researchers from the University of Geneva (UNIGE), Switzerland, has designed a family of molecules capable of binding to metal ions present in its environment and providing an easily detectable light signal during binding. This new type of sensor forms a 3D structure ...

A computational method for designing a new type of 2D carbons

16-Aug-2018

Zeolites are porous minerals that occur both naturally but also are being synthesized artificially. Because of their stability and durability, they are used in industrial water purification, catalysis, adsorption, and even in blood-clotting powders (e.g. QuickClot used by the US military). A ...

New approach to terpene syntheses

01-Aug-2018

Terpenes are natural products that are often very difficult to synthesize in the laboratory. Chemists from the University of Basel have now developed a synthesis method that mimics nature. The decisive step takes place inside a molecular capsule, which enables the reaction. Terpenes are the ...

Soil bugs munch on plastics

27-Jul-2018

Thin mulch films made of polyethylene are used in agriculture in numerous countries, where they cause extensive soil contamination. Researchers at ETH Zurich and Eawag have now identified an alternative: films made of the polymer PBAT biodegrade in soils. Our world is drowning in a flood of ...

Electrical contact to molecules in semiconductor structures established for the first time

16-Jul-2018

Electrical circuits are constantly being scaled down and extended with specific functions. A new method now allows electrical contact to be established with simple molecules on a conventional silicon chip. The technique promises to bring advances in sensor technology and medicine, as reported in ...

A step closer to single-atom data storage

13-Jul-2018

Despite the rise of solid-state drives, magnetic storage devices such as conventional hard drives and magnetic tapes are still very common. But as our data-storage needs are increasing at a rate of almost 15 million gigabytes per day, scientists are turning to alternative storage devices. One of ...

INEOS Announces €2.7 Billion investment in new European Chemical Complex

INEOS commits to building a new world scale chemical cracker and PDH plant in North West Europe

06-Jul-2018

INEOS has approved a €2.7 billion capital project to build both a world scale ethane cracker and a PDH (Propane Dehydrogenation) unit in Northern Europe. Both units will benefit from US shale gas economics. This will be the first new cracker built in Europe for two decades. It will also be one of ...

Putting a quantum gas through its phases

04-Jul-2018

As a physical system undergoes a phase transition, it typically becomes more --- or, less --- ordered. For instance, when a piece of iron is heated to above the Curie temperature, the strong ferromagnetic alignment of the elementary magnetic dipole moments gives way to much weaker paramagnetic ...
