Advanced Functional Materials, EarlyView.A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Fractional Fourier Optics [PDF]
, 1995 There exists a fractional Fourier-transform relation between the amplitude distributions of light on two spherical surfaces of given radii and separation. The propagation of light can be viewed as a process of continual fractional Fourier transformation.

Advanced Functional Materials, EarlyView.A multifunctional MXene‐integrated GelMA/alginate hydrogel reinforced with TEMPO‐modified nanocellulose is engineered via dynamic covalent, ionic, and hydrogen bonding. The resulting piezoelectric, adhesive, antimicrobial, and 3D‐printable patch enables motion sensing and accelerates wound healing by promoting keratinocyte migration and collagen ...

Advanced Functional Materials, EarlyView.The internal quality factor of tantalum superconducting resonators is significantly increased by ∼140% in the low photon regime by passivating their surfaces with a high‐quality alkene self‐assembled monolayer. Our methodology promises to enhance the performance of superconducting quantum circuits.

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring
Advanced Functional Materials, EarlyView.This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.

Fractional Wavelet Transform Using an Unbalanced Lifting Structure [PDF]
, 2011 In this article, we introduce the concept of fractional wavelet transform. Using a two-channel unbalanced lifting structure it is possible to decompose a given discrete-time signal x[n] sampled with period T into two sub-signals x1[n] and x2[n] whose ...
