| Targeted demand response reduces price volatility of electric grid Posted: 23 Mar 2022 12:05 PM PDT Demand response, a measure taken to reduce the energy load in response to supply constraints, within the Texas electric grid has been a topic of recent conversation after the wake of Winter Storm Uri just one year ago. Demand response can enhance the reliability of the grid through renewable energy penetration and also significantly reduce price volatility, or fluctuation, in the wholesale electricity market. |
| Fermi Arcs in an Antiferromagnet detected at BESSY II Posted: 23 Mar 2022 09:51 AM PDT Researchers have analyzed samples of NdBi crystals which display interesting magnetic properties. In their experiments including measurements at BESSY II they could find evidence for so called Fermi arcs in the antiferromagnetic state of the sample at low temperatures. This observation is not yet explained by existing theoretical ideas and opens up exciting possibilities to make use of these kind of materials for innovative information technologies based on the electron spin rather than the charge. |
| Single-photon source paves the way for practical quantum encryption Posted: 23 Mar 2022 09:51 AM PDT Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD). |
| Quantum sensors: Measuring even more precisely Posted: 23 Mar 2022 09:51 AM PDT Two teams of physicists have designed the first programmable quantum sensor, and tested it in the laboratory. To do so they applied techniques from quantum information processing to a measurement problem. The innovative method promises quantum sensors whose precision reaches close to the limit set by the laws of nature. |
| Don’t underestimate undulating graphene Posted: 23 Mar 2022 08:45 AM PDT A theory suggests putting graphene on an undulating surface stresses it enough to create a minute electromagnetic field. The phenomenon could be useful for creating 2D electron optics or valleytronics devices. |
| Using marinated eggs to demonstrate diffusion Posted: 23 Mar 2022 08:45 AM PDT Researchers were inspired by marinated eggs to demonstrate how diffusion works in an easy and quantifiable way. The basis of the recipe is marinating hard boiled eggs in vinegar or brine, which cures the eggs by sufficiently saturating the egg whites via diffusion. In their experiment, the researchers compared penetration levels of red food dye in the whites of peeled hard-boiled eggs at three different temperatures: refrigerator temperature, room temperature, and in a cool convection oven. |
| New pumpkin shaped nucleus radiates protons with record setting rate Posted: 23 Mar 2022 07:12 AM PDT A new atomic nucleus 149-Lutetium, consisting of 71 protons and 78 neutrons, has been synthesized. |
| New advances in the protein folding process thermodynamics Posted: 23 Mar 2022 07:12 AM PDT In biophysics, the kinetic states of molecules play a determining role in the metabolic and physiological processes in which they take part. Now, a new article specifies for the first time the levels of energy, the entropy and the enthalpy of protein folding. To do so, the team used a device with optical tweezers that enables changing the experimental temperature between 5ºC and 40ºC. |
| New approach to bimetallic catalysis enhances rate through electrochemical communication Posted: 21 Mar 2022 06:19 AM PDT Researchers have developed a bimetallic catalysis technique using gold and palladium nanoparticles on a conductive support that could lead to new design pathways for greener production of renewable bio-derived fuels and chemicals. |
