Transfinite Asymptotic Dimension

open access: yes, 2013
Asymptotic property C for metric spaces was introduced by Dranishnikos as generalization of finite asymptotic dimension - asdim. It turns out that this property can be viewed as transfinite extension of asymptotic dimension. The original definition was given by Radul.

Persistent Photoluminescence Superlinearity Beyond Static Recombination Physics in Metal Halide Perovskites

open access: yesAdvanced Science, EarlyView.
Persistent intermediate photoluminescence superlinearity in metal halide perovskites challenges the conventional interpretation of β as a fixed recombination‐order indicator. Correlated steady‐state and time‐resolved measurements support a condition‐dependent carrier–lattice relaxation framework, suggesting that β and photoluminescence quantum yield ...

Multifunctional Vertical Bulk‐Heterojunction Transistors With Amorphous GaOx for Neuromorphic Perception‐to‐Decision

open access: yesAdvanced Science, EarlyView.
A multifunctional vertical bulk‐heterojunction transistor (MVBT) with amorphous GaOx integrates four functionalities within a single neuromorphic device. Gate‐source operation enables 254 nm deep‐ultraviolet sensing and threshold neuronal firing, whereas three‐terminal operation supports broadband UV–vis‐NIR synaptic functions and bias‐controlled ...

Cross‐Organ Multi‐Omics Profiling of Systemic Alterations in 5xFAD Mice and Changes Associated with Huanglian Jiedu Decoction Treatment

open access: yesAdvanced Science, EarlyView.
Cross‐organ multi‐omics reveals coordinated inflammatory and metabolic disturbances in 5xFAD mice. Huanglian Jiedu Decoction improves cognition and alleviates brain and liver abnormalities. Complementary hepatocyte–microglia conditioned‐medium experiments suggest PPAR‐γ involvement in treatment‐associated changes in microglial inflammation, providing ...

Asymptotic behaviour for Schrodinger equations with a quadratic nonlinearity in one-space dimension

open access: yesElectronic Journal of Differential Equations, 2001
We consider the Cauchy problem for the Schr"{o}dinger equation with a quadratic nonlinearity in one space dimension $$ iu_{t}+frac{1}{2}u_{xx}=t^{-alpha}| u_x| ^2,quad u(0,x) = u_0(x), $$ where $alpha in (0,1)$.

Nonlinear Dynamics and Invariants of Motion in ReRAM Cells

open access: yesAdvanced Electronic Materials, EarlyView.
A second‐order cell, hosting one capacitor and two back‐to‐back ReRAMs, admits Invariants of Motion: its states lie on one‐dimensional manifolds at all times. The cell shows quiescent monostability or bistability, depending on the manifold index. At equilibrium, the capacitor voltage vanishes.

Reference Electrode‐Free Nitrate Sensing via Differential Temperature‐Modulated Potentiometry in Printed Symmetric SC‐ISEs

open access: yesAdvanced Electronic Materials, EarlyView.
This work proposes and validates a method for measuring nitrate concentration with printed, solid‐state ion‐selective electrodes that does not require a stable reference electrode. The approach uses brief, localized heating pulses to generate a concentration‐dependent voltage response that is drift‐resilient and log‐linear from 0.1 to 100 mm, while ...

Counter‐Halide‐Directed Ion‐Pair Passivation Enables High‐Performance Wide‐Bandgap Perovskites for Perovskite/Cu(In,Ga)Se2 Tandem Solar Cells

open access: yesAdvanced Energy Materials, EarlyView.
Counter‐halide engineering of fluorobenzylammonium surface passivators reveals bromide as the optimal partner for wide‐bandgap perovskites. FBz–Br effectively stabilizes halide‐vacancy‐related defects and undercoordinated Pb sites, suppresses non‐radiative recombination, and enhances surface hydrophobicity and thermal stability.

Nickel‐Free Perovskite Solar Cells Enabled by Self‐Assembled Monolayers: A Pathway to Efficient and Recyclable Devices

open access: yesAdvanced Energy Materials, EarlyView.
Replacing toxic NiOx with phenyl‐substituted phosphonic‐acid carbazole monolayers (Ph‐5PACz) yields inverted perovskite solar cells that are efficient and recyclable. The nickel‐free interface reaches 25.3% efficiency and enables closed‐loop ITO recovery with near‐98% performance retention, while life‐cycle and techno‐economic analyses confirm lower ...
