Advanced Functional Materials, EarlyView.Carbon dots‐supported single‐atom catalysts provide a model platform for uncovering how coordination interactions regulate catalytic reactivity. Thiol binding at Ru‒N4 centers reshapes the reaction energy landscape of H2O2 activation, dynamically modulating ROS‐generation pathways through electronic‐structure perturbation.

Fourier Correlations of Dam Horizontal Movements Time Series [PDF]
Journal of Electrical and Electronics Engineering, 2008 Time deformations monitoring of Drăgandam is done by physically methods (i.e. inversependulum) and topographically methods (i.e.optoelectronic). The two deformations measuringsystems, built up by these two methods, are different.The existence of ...

Sky‐Directional Radiative Cooling Meta‐Films for Daylighting Windows
Advanced Functional Materials, EarlyView.A geometry‐mediated microprism meta‐film enables transparent, sky‐directional radiative cooling for daylighting windows. By decoupling control of visible transmittance from mid‐infrared emissivity, ground‐emitted heat absorption is suppressed while skyward heat dissipation is enhanced.

Advanced Functional Materials, EarlyView.A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...

Corrected Fourier series and its application to function approximation
International Journal of Mathematics and Mathematical Sciences, 2005 Any quasismooth function f(x) in a finite interval [0,x0], which has only a finite number of finite discontinuities and has only a finite number of extremes, can be approximated by a uniformly convergent Fourier series and a correction function.

Advanced Functional Materials, EarlyView.This work developed an all‐aqueous freeze‐thaw strategy to create a dual‐conductive PVA/P3KBT binder for high volume‐change lithium–ion battery anodes. The resulting binder system strengthens the electrode structure, supports ion and electron transport, and accommodates repeated volume changes, reducing cracking and improving long‐term cycling ...

Modular Time-Domain ECG Synthesis Using Fourier Series.
Zanin Journal of Science and EngineeringThis paper introduces a modular and transparent method for generating ECG-like synthetic signals in the time domain based on the Fourier series. Each part of the cardiac cycle P, Q, R, S, T, and U waves is modeled separately using simple analytical time-
