source:resource-recyclingA technology that will allow recyclers to extract valuable metals from e-scrap like shredded hard drives without affecting the other materials is entering its pilot plant stage.Daniel Bina, CEO of Critical Materials Recycling and TdVib, said the new method will make rare earth recycling more accessible at a time when there is a critical need for more domestic supply.The method, called acid-free dissolution reaction (ADR), is unique because it can selectively target rare earths and doesn’t use acids to do so, according to Bina. It was developed at the Critical Materials...

source：phys.orgCrystalline lithium niobate (LN) is considered the 'silicon of photonics' because of its outstanding optical properties, including a broad transparency window and high piezoelectric, acousto-optic, second-order nonlinear, and electro-optic coefficients, which are critical for photonic integrated circuit (PIC) applications. Recent breakthroughs in nanofabrication technology facilitate a variety of high-performance integrated photonic devices on thin-film LN, such as ultrafast electro-optic modulators, broadband optical frequency combs, and high-efficiency optical frequenc...
