Small organic molecules underpin modern life, from medicines and flavours to advanced materials. Much of this functional diversity comes from shape: modest changes in a molecule's 3D structure can completely change its properties.
The body of the robotic fingers is built from polyglycerol sebacate, a synthetic elastomer made from glycerol and sebacic acid. Glycerol is a byproduct of biodiesel production while sebacic acid is derived from castor oil, and both of them are plant-based. Polyglycerol sebacate is safe since it is already used in medical implants because the body can absorb it without a toxic response.
Korea Zinc, which it described as one of the world's largest smelters, is in talks with major US technology firms to recycle data center waste and extract rare earth. The move comes almost one year to the day after China announced immediate export controls on seven more rare earth elements critical to enterprise IT hardware manufacturing.
Crude oil is a complex mixture of hydrocarbons - molecules made mainly of carbon and hydrogen. Refineries and chemical plants separate and transform these molecules into smaller chemical building blocks known as petrochemicals. Some of the most important petrochemical building blocks include chemicals such as ethylene, propylene and benzene.
When the Finnish startup unveiled its battery at the Consumer Electronics Show in January, the specifications shocked the battery industry. How could an unknown company leapfrog Toyota, Factorial, and CATL in the solid-state race? The startup claimed 400 watt-hours per kilogram of energy density, a 100,000-cycle lifespan and a charge time of roughly five minutes.
Now, researchers have created an artificial-intelligence system that vastly simplifies and accelerates the process of chemical synthesis. The system, which is called MOSAIC and is described in a study published in Nature on 19 January, recommended conditions that researchers were able to use to generate 35 compounds with the potential to become products like pharmaceuticals, agrochemicals or cosmetics without needing to do any further trawling or tweaking.
We demonstrate how the apparent magnetic field induced lattice and CDW intensity change can be explained as a consequence of two independent experimental artifacts: a reconfiguration of atoms at the STM tip apex that alters the amplitudes of CDW modulations, and piezo creep, hysteresis and thermal drift, which artificially distort STM topographs.
Calling nanoscientists: your field needs you to try to replicate a landmark finding that quantum dots can act as biosensors inside living cells. As part of the first large-scale effort in the physical sciences to tackle the reproducibility crisis, researchers in France and the Netherlands are offering funds and resources in exchange for a few months of work. "We are trying to use
