It consists of carbon, cellulose, glycerin and table salt. And it works reliably. |
| Are wind farms slowing each other down? Posted: 03 Jun 2021 02:12 PM PDT Many countries promote the expansion of wind farms. However, if these offshore wind farms are set up close to each other, wind energy and hence electricity yield is reduced. A study shows that the losses with increasing offshore wind energy production will be considerable and detectable as large scale pattern of reduced wind speed around wind farms. |

| Enantiomorph distribution maps for metals and metallic alloys Posted: 03 Jun 2021 02:00 PM PDT Left- or right-handedness is a symmetry property that many macroscopic objects also exhibit and which is of immense importance, particularly for the bioactivity of organic molecules. Chirality is also relevant for physical or chemical properties such as optical activity or enantioselectivity of crystalline solids or their surfaces. In the case of chiral metallic phases, unconventional superconductivity and unusual magnetic ordered states are linked to the chirality of the underlying crystal structure. Despite this connection between chirality and the properties of a material, detection is often difficult because left-handed and right-handed structural variants can cancel each other out or at least weaken chirality effect. |
