Man versus machine: Can AI do science?

15-Jan-2020

Over the last few decades, machine learning has revolutionized many sectors of society, with machines learning to drive cars, identify tumors and play chess - often surpassing their human counterparts. Now, a team of scientists based at the Okinawa Institute of Science and Technology Graduate ...

Five-fold boost in formaldehyde yield

15-Nov-2019

Environmentally benign methods for the industrial production of chemicals are urgently needed. LMU researchers recently described such a procedure for the synthesis of formaldehyde, and have now improved it with the aid of machine learning. Formaldehyde is one of the most important feedstocks ...

An ultrafast glimpse of the photochemistry of the atmosphere

15-Oct-2019

Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols. The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between ...

Molecular motors: Rotation on an eight-shaped path

Chemical engineers have developed the first molecular motor that enables an eight-shaped movement

04-Oct-2019

Molecular motors convert externally supplied energy into directional motions and are thus an important basis for future applications in nanotechnology. The first such motors were developed in the late 1990s, and since then a growing number of different systems have been established. A specialist ...

One transistor for all purposes

Organic semiconductors

22-Mar-2019

In mobiles, fridges, planes – transistors are everywhere. But they often operate only within a restricted current range. LMU physicists have now developed an organic transistor that functions perfectly under both low and high currents. Transistors are semiconductor devices that control voltage ...

Semiconductors: No support needed

Scientists at LMU are the first to fabricate freely suspended, ultrathin, organic semiconductor films

08-Mar-2019

In recent years, interest in the investigation of several organic semiconductor materials has steadily increased. These compounds promise easier and cheaper fabrication without the need for scarce elements, as well very favorable electrical switching characteristics and correspondingly high ...

Solid-state catalysis: Fluctuations clear the way

19-Feb-2019

LMU chemists have identified a mechanism that allows molecules to diffuse rapidly on the already crowded surface of a solid-state catalyst – an important capability, especially for efficient catalysis under industrial conditions. The use of efficient catalytic agents is what makes many technical ...

Molecular motors: Chemical carousel rotates in the cold

26-Nov-2018

LMU chemists have developed the first molecular motor that can be powered by light alone. Its operation is therefore essentially independent of the temperature. Molecular motors, which rotate unidirectionally in response to an external energy input, constitute an important class of components for ...

All-in-one light-driven water splitting

10-Sep-2018

Solar-powered water splitting is a promising means of generating clean and storable energy. A novel catalyst based on semiconductor nanoparticles has now been shown to facilitate all the reactions needed for “artificial photosynthesis”. In the light of global climate change, there is an urgent ...

Biomimetic chemistry: Carbohydrate capture

27-Aug-2018

LMU chemist Professor Ivan Huc, who heads a research group devoted to the study of Biomimetic Supramolecular Chemistry, has designed and synthesized a molecular structure which features a helical binding pocket that is made-to-measure for the recognition and capture of xylobiose, a member of the ...
