    This city is being designed to scrub the air of pollution

    Liuzhou Forest City

    China's approach to reversing climate change is firm and innovative.

    Covering an area of approximately 175 hectares along the Liuzhou River, Forest City will have offices, houses, hotels, hospitals, and schools that will be entirely covered by a total of 40,000 trees and close to a million plants, including over 100 species. It will be connected to the main city of Liuzhou by a rail line with electrical train cars.

    This will also be the first urban settlement in China that will be able to "generate its own renewable energy, increase biodiversity, and effectively reduce urban air pollution—which is a major challenge for present-day China."

    Barberry and Ticks

    You might not want this deceptively attractive plant in your yard if you have dogs or cats.

    A study by University of Connecticut shows that areas with the presence of Berberis thunbergii are more likely to have Lyme disease-carrying ticks:

    Williams recites the numbers. ”When we measure the presence of ticks carrying the Lyme spirochete (Borrelia burgdorferi) we find 120 infected ticks where Barberry is not contained, 40 ticks per acre where Barberry is contained, and only 10 infected ticks where there is no Barberry.”

    Piezoelectrics

    Material can turn sunlight, heat and movement Into electricity -- all at once

    Extracting energy from multiple sources could help power wearable technology.

    A perovskite solid-solution that exhibits tunable bandgaps in the visible light energy range is showing promising material for light absorption and conversion applications,(solar energy harvesting and light sensing).

    Such a common ABO3–type perovskite structure, most widely used for ferroelectrics and piezoelectrics, enables the same solid-solution material to be used for the simultaneous harvesting or sensing of solar, kinetic, and thermal energies.

    These results are considered to be a significant improvement compared to those of other compositions which could be used for the same applications. The results pave the way for the development of hybrid energy harvesters/sensors, which can convert multiple energy sources into electrical energy simultaneously in the same material.

    Biofuel_algae

    Biofuel-producing algae can now be farmed 10x faster than before

    New process moderates temperature of grow environment

    When the microalgae is first seeded, it’s kept at 15 degrees celsius, which makes it a solution. When it’s heated by just 7 degrees, it becomes a gelatinous mixture in which microalgae grows in clusters 10x larger than in the regular medium. Finally, it’s cooled again for harvesting, at which point it turns back into a solution, which can be separated using gravity.

    Cement that generates Light

    Carlos Rubio Ávalos of the UMSNH of Morelia, developed a cement with the capacity to absorb and irradiate light energy,

    The researcher claimed that the applications are very broad, and those which stand out most are for the architectural market: facades, swimming pools, bathrooms, kitchens, parking lots, etc. It would also be useful in road safety and road signs, in the energy sector, such as oil platforms, and anywhere you want to illuminate or mark spaces that don’t have access to electricity since it doesn’t require an electrical distribution system and is recharged only with light. The durability of light-emitting cement is estimated to be greater than 100 years thanks to its inorganic nature, and its material components are easily recyclable.
