On some problems of M.Z. Nashed on outer inverses
Linear Algebra and its Applications, 1986 Let X, Y be Banach spaces and let L(X,Y) consists of all linear bounded operators mapping X into Y. Main results: 1) Every \(A\in L(X,Y)\) has a bounded outer inverse, i.e. there exists a \(B\in L(Y,X)\) such that \(BAB=B.\) 2) \(A\in L(X,Y)\) has an outer inverse B such that dim BY\(=+\infty\) if and only if there exists a subspace \(X_ 0\subset X ...

Advanced Materials, EarlyView.The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Matrices having nonzero outer inverses
The Electronic Journal of Linear AlgebraIt is well known that every nonzero von Neumann regular $m\times n$-matrix $A$ over an arbitrary ring $R$ has a nonzero outer inverse $n\times m$-matrix $B$ in the sense that $B=BAB$. Generalizing previous work on von Neumann regular matrices, the matrices having nonzero outer inverses over semiperfect rings are characterized as the matrices having ...

Advanced Materials, EarlyView.Selective methane (CH4) photooxidation emerges from architectural decoupling of activation and preservation. Programmable organic semiconductor frameworks spatially organize oxidative flux and intermediate residence, separating reaction zones from product domains to synchronize activation strength with stabilization and establish a selective oxidation ...

Recent Advances in Ferrite‐Based Materials for Biomedical Applications: A Comprehensive Review
Advanced Materials, EarlyView.Ferrite nanoplatforms are presented as tunable biomedical materials in which synthesis control, cation engineering, defect/morphology regulation, and surface functionalization govern structure–property–bioactivity relationships. These design strategies enable multifunctional applications including MRI contrast, magnetic hyperthermia, targeted drug ...
