Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction
Advanced Science, EarlyView.Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Advanced Science, EarlyView.Ultraviolet (UV) imagers are important for a variety of applications but often require dedicated semiconductor process flows. Here, a versatile capacitive CMOS platform is transformed into a visible‐blind, multispectral UV imager through post‐CMOS functionalization with solution‐processed metal‐oxide nanoparticles. The UV‐induced photodielectric effect

Polar Orbits around the Newly Formed Earth–Moon Binary System
The Astrophysical JournalWe examine the dynamics and stability of circumbinary particles orbiting around the Earth–Moon binary system. The moon formed close to the Earth (semimajor axis a _EM ≈ 3 R _⊕ ) and expanded through tides to its current day semimajor axis ( a _EM = 60 R ...

Unveiling the Mechanism for the Rapid Acceleration Phase in a Solar Eruption
The Astrophysical Journal Letters, 2023 Two major mechanisms have been proposed to drive the solar eruptions: the ideal magnetohydrodynamic instability and the resistive magnetic reconnection. Due to the close coupling and synchronicity of the two mechanisms, it is difficult to identify their ...

Indian Calendar System in Islamic Astronomy Perspective [PDF]
, 2022 The Indian calendar, or the Indian calendar system, is a unique calendar. This is because many regions have their own version of the calendar. The Indian calendar uses two calendar systems in general, namely, according to solar calculations and according

Quantum‐Trained AI Enables Inverse Design of Organic Frontier Orbitals at Billion‐Scale
Advanced Science, EarlyView.Quantum‐trained AI links molecular substructures to frontier‐orbital energetics and enables interpretable screening across nearly one billion GDB‐13 molecules. By combining fragment‐ and ring‐level insights with donor–acceptor energy alignment against ITIC, the framework narrows an immense chemical space to a small set of promising candidates and ...
