#weekendusers Nanoparticles for medical diagnosis and therapy

30-09-2016

Nanomedicine is steadily becoming a hot topic. A team from the Southern Federal University in Rostov, Russia, will spend the weekend studying colloidal iron-oxide based magnetic nanoparticles of 5 to 40 nanometers in size that could be used for cancer theranostics (i.e....

X-ray ghost imaging using individual synchrotron pulses

27-09-2016

Ghost imaging is an indirect method in which most of the X-rays used for the experiment never actually interact with the sample. The first demonstration of X-ray ghost imaging has been carried out at beamline ID19. The method uses two copies of the same speckled beam...

#weekendusers How do iron minerals behave in marine ecosystems altered by humans?

23-09-2016

Every day, human activity affects marine ecosystems by discharging waters from urban and agricultural areas. Dutch users investigate what role iron minerals play in the health of these ecosystems, using the X-rays of the Dutch-Belgian beamline (DUBBLE).

Tracking down the origin of mercury contamination in human hair

22-09-2016

Mercury is a potent neurotoxin present in our daily lives and our body can accumulate it over the years. Food consumption, such as fish and rice, is the most common source of mercury exposure. Mercury can be found in dental amalgams, compact fluorescence lamps, vaccines,...

A Passion for Science

20-09-2016

The ESRF/ILL International Student Summer Programme is helping students to take one step nearer to their dreams. Viktor Radermacher has blisters on his hands but a huge smile on his face. The blisters are from carrying the 8kg case containing a precious dinosaur fossil...

#weekendusers Express experiments for better health

19-09-2016

Synchrotron sources are crucial for structural biology and research performed at the ESRF produces 40% of the protein structures submitted in Europe. This weekend, scientists from Barcelona spent 24 hours trying to unveil the structures of medically-relevant proteins.

Combining operando X-ray techniques to study lithium ion batteries

CoverImage
13-09-2016

Operando X-ray tomographic microscopy (SRXTM) and scanning X-ray diffraction (SXRD) have been combined for the first time to study dynamic processes in a lithium ion battery. This combination of techniques allowed the lithiation processes to be tracked throughout the...

#weekendusers Nanofocusing at high energies

09-09-2016

This weekend, Markus Osterhoff, Christian Eberl and Jakob Soltau, three young scientists from the University of Göttingen, in Germany, are testing a new nanofocus optics device for microscopy experiments on the high energy beamline ID31.

Life history of the 360-My-old tetrapod Acanthostega rewrites the tetrapod move onto land

07-09-2016

This week in the journal Nature, a team of researchers from Uppsala University in Sweden, the European Synchrotron Radiation Facility (ESRF) in France and the University of Cambridge in the United Kingdom shows that fossils of the 360 million-year-old tetrapod Acanthostega,...

Watching the birth of a nanocrystal superlattice

05-09-2016

Two-dimensional systems have recently emerged as very promising candidates for future electronic devices. An ordered 2D array of nanocrystals can be created by letting nanocrystals self-assemble and connect at a liquid surface. This new structure shows excellent long...

#weekendusers How does nature make a colour whiter than white?

02-09-2016

This question puzzles a team from the University of Sheffield in the UK working this weekend on ID16B. The Cyphochilus (occurring in South East Asia) and Lepidiota stigma beetles produce an exceptionally white colour, using only a thin layer of material, in the range...

The force unleashed: how forces are transmitted through grain piles

30-08-2016

The behaviour of granular materials under pressure is important for a wide variety of subjects such as pharmaceutical pill manufacturing, food processing and even natural events such as earthquakes. Deciphering how grains, like sand or wheat, move when compressed can...

#weekendusers Getting to the bottom of bones with new instrument

26-08-2016

Osteoporosis affects millions of patients around the world and is characterised by a reduction of bone strength that results in increased rates of fractures. The irreversible mechanical behaviour of bone is currently well characterised at the organ level. The behaviour...

X-ray colour provides direct 3D information in crystallographic texture measurements

25-08-2016

Preferred crystal orientation (crystallographic texture) is a common phenomenon in many complex micro- and nanocrystalline materials of biological and synthetic origin. Conventionally, texture determination by XRD involves sample 2D diffraction images combined into...
