Densifying of urban territories

Mokslas: Lietuvos Ateitis, 2011
In the 20th century city dwellers started facing various kinds of problems determined by the expansion of cities. Territorial growth caused serious environmental problems, intensive traffic and increased criminal behavior. For more than one hundred years

Bionic Solar‐Powered Heavy Metal Trap for Eco‐Friendly Sludge Drying and Simultaneous Electricity Generation

Advanced Science, EarlyView.
Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

Scaling and universality in the micro-structure of urban space [PDF]

, 2003
We present a broad, phenomenological picture of the distribution of the length of open space linear segments, $l$, derived from maps of 36 cities in 14 different countries.

Hydrothermal Embedding of Pd Single Atoms Into SnO2 for Efficient CO Oxidation

Advanced Science, EarlyView.
By applying hydrothermal regulation to SnO2‐supported PdO, we achieve atomic dispersion of Pd into the SnO2 lattice, which activates the lattice oxygen neighboring Pd atoms to generate oxygen vacancies and facilitates subsequent O2 activation, thereby promoting CO oxidation to proceed via a low‐energy‐barrier MvK pathway while avoiding CO poisoning ...

Effects of climate conditions in formation and development of Zonuz's historical garden city architecture

Journal of Architecture and Urbanism, 2015
Zonuz architecture has originated from prehistoric era by having worthwhile architectural signs of the Kura – Aras culture related to Bronze Age (3800 BC), as seen in Qiz Qala and Oğlan Qalasi, located about 5 km from the city.

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, EarlyView.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...
