Fate of silver nanoparticles in agricultural soils amended with sewage sludge

23-05-2016

Silver nanoparticles released from consumer products end up in waste water treatment plants and may then be transferred to agricultural soils through the use of sewage sludge as fertiliser. Results from this study challenge the current idea that silver nanoparticles...

Nanoparticle uptake in worms

17-05-2016

This image shows a 3D rendering of the tiny roundworm Caenorhabditis elegans, which was exposed to cobalt nanoparticles in soil and then fixed in a quartz capillary. C. elegans is a model organism for exposure experiments because it has a short lifecycle and, being...

Experimental realisation of single-atom magnets

10-05-2016

The existence of single-atom magnets has been proven by X-ray magnetic circular dichroism. Monodisperse holmium atoms adsorbed on a nonmagnetic MgO thin film display magnetic hysteresis up to a temperature of 30 K and with magnetic relaxation time of the order of 1500...

Getting to the heart of fossils

29-04-2016

Scientists have discovered, for the first time, a fossilised heart in a 119 million-year-old fish from Brazil called Rhacolepis. This has been possible thanks to the powerful X-rays of the ESRF, the European Synchrotron Radiation Facility, Grenoble, France. This breakthrough...

New type of charge-ordering transition in the novel iron oxide Fe4O5

28-04-2016

Synthesis of new classes of compounds can lead to discoveries of novel physical phenomena as well as innovative applications. Fe4O5 is the first member of a very recently discovered family of iron oxides that can be synthesised only under high-pressure conditions. A...

X-rays enable a direct view inside biological cells

14-04-2016

Structures within intact biological cells have been resolved quantitatively at the nanoscale using a combination of ptychography and scanning X-ray nanodiffraction. Employed sequentially, these techniques provided high resolution real space and reciprocal space images...

Real-time X-ray imaging of silicon wafer fracture

01-04-2016

Fracture and breakage of single crystal silicon wafers is a severe problem for the semiconductor industry leading to million dollar costs. This is a fast and multi-lengthscale process: a crack starts on an atomic scale, forms crack fronts on a micrometre scale and ends...

Where science never sleeps

30-03-2016

Sleepless night are common among scientists that come to the ESRF to carry out experiments. They all know too well that precious beamtime should be used to the maximum, so working 24 hours a day is not unusual. Now a team from Nature magazine has followed different...

Observation of superconductivity in H2S by nuclear resonant scattering

18-03-2016

The Meissner effect is used as proof of the superconducting nature of a material and typically demonstrated by the levitation of a magnet as the material reaches its superconducting state. A new approach was needed to study a superconductor created inside a high pressure...
