Intelligent Solar Tracking System
The growing demand for renewable energy has increased the importance of maximizing solar power generation. Solar panels produce maximum energy when they are oriented perpendicular to the sun's rays. However, fixed solar panels fail to maintain optimal alignment throughout the day.

Advanced Science, EarlyView.An exogenous reagent‐free dual‐substrate strategy harnesses phenol as an intrinsic electron donor to drive synchronous phenol degradation and Cr(VI) reduction over modified carbon nitride. π–π stacking and hydrogen bonding direct electron transfer to the catalyst, enriching photogenerated electrons and accelerating Cr(VI) reduction 6.4‐fold. This waste‐

Advanced Science, EarlyView.The integration of rare‐metal neodymium centers to engineer Lewis acid sites with nickel centers is proposed as highly efficient UOR catalysts. ABSTRACT The sluggish kinetics of the urea oxidation reaction (UOR) are strongly associated with the high energy barriers required for the C‐N cleavage and N‐N coupling steps.

Advanced Science, EarlyView.A BCP‐derived buried‐interface strategy establishes Na‐BCS as a chemically bonded molecular bridge. By combining sulfonate anchoring to SnO2 with preserved BCP–Pb2+ coordination, Na‐BCS simultaneously passivates oxide‐ and perovskite‐side defects, suppresses non‐radiative recombination, and delivers a surface recombination velocity of 8.6 cm s−1, a ...

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates
Advanced Science, EarlyView.Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...
