Monitoring gene activities in living cells
Cell Biopsy instead of cell lysis
19-Aug-2022
Researchers from ETH Zurich and EPFL are expanding the emerging field of single-cell analysis with a ground-breaking method: Live-seq makes it possible to measure the activity of thousands of genes in a single cell without having to isolate and destroy it. Modern biology is increasingly ...
Carbyne – an unusual form of carbon
International team of researchers investigates optical band gap of carbon compound
13-Nov-2020
Which photophysical properties does carbyne have? This was the subject of research carried out by scientists at FAU, the University of Alberta, Canada, and the Ecole Polytechnique Fédérale de Lausanne in Switzerland, which has led to a greater understanding of the properties of this unusual form ...
"Simulation microscope" examines transistors of the future
"We have created one of the largest databases of transistor materials"
12-Aug-2020
Since the discovery of graphene, two-dimensional materials have been the focus of materials research. Among other things, they could be used to build tiny, high-performance transistors. Researchers at ETH Zurich and EPF Lausanne have now simulated and evaluated one hundred possible materials ...
Visualizing chemical reactions
On the way to synthetic fuels
10-Jan-2020
Researchers at the joint EPFL-Empa lab in Sion have developed a reactor system and an analysis method that has allowed them to observe the real-time production of synthetic natural gas from CO2 and H2 for the first time. Infrared (IR) thermography is used to determine the temperature of humans ...
Emergence of calorie burning fat cells
A new approach to treating overweight and obesity
10-Jan-2020
1.9 billion people in the world are overweight. Of these, 650 million people are obese, which increases the risk of secondary diseases such as high blood pressure or cancer. Professor Martin Klingenspor and his team at the Technical University of Munich (TUM) examine how our fat metabolism ...
Adding a polymer stabilizes collapsing metal-organic frameworks
22-Jul-2019
Metal-organic frameworks (MOFs) are a special class of sponge-like materials with nano-sized pores. The nanopores lead to record-breaking internal surface areas, up to 7800 m2 in a single gram. This feature makes MOFs extremely versatile materials with multiple uses, such as separating ...
New biologically derived metal-organic framework mimics DNA
10-Apr-2019
The field of materials science has become abuzz with "metal-organic frameworks" (MOFs), versatile compounds made up of metal ions connected to organic ligands, thus forming one-, two-, or three-dimensional structures. There is now an ever-growing list of applications for MOF, including separating ...
Chirality in 'real-time'
Circular dichroism in the deep ultraviolet
11-Jan-2019
In nature, certain molecules with the same chemical composition, can exist in two different shapes that are mirrors images of each other, much like our hands. This property is known as "chirality" and molecules with different chirality are called enantiomers. Enantiomers can exhibit entirely ...
Nitrogen fixation in ambient conditions
13-Nov-2018
Abundant in nature (78% of the air we breathe), nitrogen is rarely used in the industrial production of chemicals, with the most important process being the synthesis of ammonia, which is in turn used for the preparation of agricultural fertilizers. Using nitrogen as a raw material ("feedstock") ...
Metal-organic frameworks cut energy consumption of petrochemicals
19-Mar-2018
In the chemical and the petrochemical industries, separating molecules in an energy-efficient way is one of the most important challenges. Overall, the separation processes account for around 40% of the energy consumed in the petrochemical industry, and reducing this can help addressing ...
q&more – the networking platform for quality excellence in lab and process
The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors.
