The primary challenge for synthetic chemists is supporting the efficient exploration of chemical space to find the best molecules for understanding or solving problems. In the past decade, cross-electrophile coupling, the union of two different electrophiles through transition-metal catalysis under reducing conditions, has become an increasingly used tool in these ...
There is a rapidly growing demand for reliable, low-cost trace gas sensors, particularly for hydrogen, in energy and critical infrastructure applications. These systems require ppb-to-ppm sensitivity, high intrinsic selectivity, and ultra-low power operation??"requirements that are not simultaneously met by today’s commercial gas-sensing technologies due to fundamental limitations in materials, device ...
Quantum computing promises to solve classically intractable problems, but building useful systems requires a fault-tolerant logical architecture for protecting and processing quantum information. After decades of progress, the field has largely converged on the surface-code architecture, which nevertheless appears fundamentally difficult to scale, with practical applications likely requiring millions of ...
Earth’s oceans are warming. Such large-scale aspects of climate change are disrupting important ecological balances, including the delicate service sea urchins perform in California’s kelp forest ecosystem. The implications are broad and alarming (and addressable): a warming planet may cause collapse in wild populations of vital marine life.Speaker: Daniel Okamoto, ...
