The Technical Research Centre of Finland (VTT) has carried out studies on the emissions from municipal solid waste (MSW) that pose a threat to sustainable development. The results show that current landfills, as well as those scheduled to be constructed in the near future, may discharge environmentally hazardous emissions even 100-200 years into the future. Globally, the target is to ensure each landfill site is closed and its harmful emissions stopped within 50 years of the sites establishment.
The study shows that even todays well-designed landfills may emit significant amounts of carbon or nitrogen-based nutrients, hazardous metals dissolved in leachate, or methane - a powerful greenhouse gas - even 100-200 years after the sites construction.
Globally, the primary target is to increase waste recycling and recovery and then dispose of the residue in ways that allow the landfill to be redeveloped as a sustainable part of the environment within 50 years of its establishment. In accordance with EU legislation, most of the emissions dissolved in leachate or methane may be collected from sealed landfills for 50-100 years. However, there is later a risk of leakage from the bottom liner and surface sealing, in which case the landfills emissions into the environment will once again increase.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.
In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
