Monitor Sustainable Municipalities Report 2019 Key topic Circular Economy. Bertelsmann Stiftung Study 4 November 2019 [PDF]
At first sight, the concept for a recycling economy appears to be just the latest trend in the field of urban development, but in fact conversion to circular value creation also contains numerous oppor-tunities for the creation of long-term sustainable ...

Ozone‐based gas‐phase metal‐assisted chemical etching enables unprecedented room‐temperature fabrication of high‐quality silicon nanowires. The superior oxidation potential of O3 drives rapid vertical etching (1 µm min−1) while maintaining exceptional structural integrity. The pristine nanowire surfaces enable high‐performance core‐shell photodetectors

Literature Review on Thermodynamic and Kinetic Limitations of Thermal Decomposition of Methane
The state of the art in methane pyrolysis does not yet provide a definitive answer as to whether the concept of an elementary reaction is universally applicable to the apparently simple process of methane dissociation. Similarly, the literature currently

Deterministic Writing of Field‐Free and Unipolar Spin‐Transfer Torque Magnetic Random‐Access Memory
Deterministic unipolar‐switching STT‐MRAM with field‐free operation is experimentally demonstrated. The device features a compact 4F2 cell architecture using a diode as the access device and a single magnetic tunneling junction. Unlike conventional bipolar switching STT‐MRAM requiring a three‐terminal access transistor in the array, this design offers ...
