Advanced Materials, EarlyView.Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis
Advanced Materials, EarlyView.Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Energetic Offset in Organic Solar Cells‐ Importance, Confusion and Outlook
Advanced Materials, EarlyView.Energetic offsets in organic solar cells (OSCs) remain a subject of debate due to measurement‐ and lab‐dependent discrepancies. This Perspective clarifies the physical origins of these variations and identifies temperature‐dependent electro‐optical methods as a reliable approach to obtain consistent offset values.

QUANTUM BEATS OF EXCITONS IN QUANTUM WELLS
Modern Physics Letters B, 1990We briefly review our recent observations of quantum beats of excitons in quantum wells. The quantum beats are observed as an oscillatory structure in the polarization decay of energetically closely spaced excitons which are coherently excited by ultrashort laser pulses.

Few-Body Systems, 2001
The ground-state energy of three-particle systems consisting of electrons and holes as found in semiconducting quantum wells is studied. The degree of confinement is determined by the quantum-well width and we can vary the dimensionality of the system from two to three dimensions.

Nonlinear gain effects in quantum well, quantum well wire, and quantum well box lasers
IEEE Journal of Quantum Electronics, 1991The nonlinear gain effects due to the spectral hole burning in quantum well (QW), quantum well wire (QWW), and quantum well box (QWB) lasers are discussed. It is found that the gain nonlinearity is enhanced by the quantum confinement of carriers, and is further enhanced in the QWW and QWB lasers.

Quantum Well Shape Modification in Quaternary Quantum Wells
MRS Proceedings, 1991ABSTRACTQuantum well interdiffusion has been employed, for the First time in the quaternary InGaAsP/InP system (grown lattice matched to InP substrates), in order to modify the as-grown, nominally square, shapes of single quantum wells so as to increase their bandgap energies.
