Grain‐Size‐Controlled Resistive Switching Memories Enabling Domain‐Specific Functionality for Real‐Time Video Signal Processing

open access: yesSmall, EarlyView.
Grain‐size‐controlled resistive switching memory arrays based on Sn‐halide perovskite thin films are realized via a photo‐thermochemical process that creates lateral grain‐size gradients. The arrays exhibit domain‐specific volatile threshold switching and short‐term neural dynamics, enabling nonlinear conductance, tunable relaxation, integrate‐and‐fire,

Reactivity of Oxidized Porous Silicon with Calcium Ion in Aqueous Media: Stability, pH Behavior, and Host‐Guest Strategies

open access: yesSmall, EarlyView.
Oxidized porous silicon, composed of an elemental silicon porous skeleton coated with a silica shell, reacts with aqueous Ca2+ to generate a mixed silica–calcium silicate matrix that is remarkably efficient at trapping small molecules. With an emphasis on the engineering of controlled‐release drug delivery systems, this study identifies the factors ...

A Bilayer Rare‐Earth/High‐κ Oxide Memristor for Energy‐Efficient Neuromorphic Intelligence

open access: yesSmall, EarlyView.
Interface‐engineered Gd2O3/HfO2 bilayer memristors demonstrate controlled filament formation, ultralow switching energy (∼13.56 pJ), and fast operation (∼350 ns) with a high ON/OFF ratio (∼107). The devices exhibit stable analog synaptic behavior and enable pattern recognition on Fashion‐MNIST, underscoring their promise for energy‐efficient ...

Biomaterial‐Integrated Electroporation for Therapeutic Delivery: From Gene Editing to Tumor Ablation and Immune Modulation

open access: yesSmall, EarlyView.
Biomaterial‐integrated electroporation establishes a programmable therapeutic interface that coordinates electric‐field modulation, transient or irreversible membrane permeabilization, cargo stabilization, and immune remodeling. This Review highlights how nanocarriers, hydrogels, and bioelectronic interfaces expand electroporation from conventional ...

Hybrid microscopic-mesoscopic traffic simulation

open access: yes, 2004
Traffic simulation is an important tool for modelling the operations of dynamic traffic systems and helps analyse the causes and potential solutions of traffic problems such as congestion and traffic safety. Microscopic simulation models provide a detailed representation of the traffic process, which makes them most suitable for evaluation of ...
