Tuning the Structure and Photoluminescence of [SbCl]-Based Halides via Modification of Imidazolium-Based Cations.

Structure-property relationships in imidazolium-based hybrid Sb(III) chlorides provide critical guidance for designing high-performance materials. Three zero-dimensional metal halides, namely, [Cmmim]SbCl (, [Cmmim] = 1-propyl-2,3-dimethylimidazolium), [Cmmim]SbCl (, [Cmmim] = 1-pentyl-2,3-dimethylimidazolium), and [Cmim]SbCl (, [Cmim] = 1-pentyl-3-methylimidazolium), are synthesized by ionothermal methods. These compounds exhibit markedly distinctly photophysical properties at their optimal excitation wavelengths.

Neuro-dynamic programming-based event-triggered fault tolerant control for nonlinear systems with multiple faults.

Existing neuro-dynamic programming (NDP)-based fault-tolerant control (FTC) methods typically focus exclusively on actuator faults while neglecting sensor faults, and their online implementation is constrained by the strict persistence of excitation (PE) condition and the initial admissible control. This paper presents an online FTC scheme for uncertain nonlinear systems characterized by multiple faults. By integrating two neural networks (NNs) within a neuro-observer, the proposed approach simultaneously reconstructs accurate system states and estimates both actuator and sensor faults.

Humidity-Triggered Reversible 0-1D Phase Transition in Hybrid Antimony Halides.

Stimulus-responsive inorganic-organic hybrid metal halides (IOMHs) have shown great potential in applications such as sensing and anti-counterfeiting. IOMHs can undergo a variety of structural changes when triggered by humidity; however, relevant reports of structural dimensionality change from zero dimension (0D) to one dimension (1D) are rare. This study investigates the synthesis, structure, and properties of two antimony-based IOMHs, namely 0D-(Mp)SbCl·MeCN and 1D-(Mp)SbCl (Mp = protonated morpholine; MeCN = acetonitrile).

A data-driven group retrosynthesis planning model inspired by neurosymbolic programming.

Deep generative models have garnered significant attention for their efficiency in drug discovery, yet the synthesis of proposed molecules remains a challenge. Retrosynthetic planning, a part of computer-assisted synthesis planning, addresses this challenge by recursively decomposing molecules using symbolic rules and machine-trained scoring functions. However, current methods often treat each molecule independently, missing the opportunity to utilize shared synthesis patterns and repeat pathways, which may contribute from known synthesis routes to newly emerging, similar molecules, a notable challenge with AI-generated small molecules.

Large mode-field area multi-element silica glass fibers for gigahertz ultrafast lasers.

Multi-gigahertz ultrafast fiber lasers are critical for many significant applications, including bioimaging, optical communications, and laser frequency combs. The gain fiber which is expected to simultaneously satisfy large mode-field area, highly gain coefficient and resistance to photodarkening, will effectively protect mode-locked materials/devices that generally possesses low damage threshold (<10 mJ/cm) and enhance stability in the centimeter-scale fiber lasers. However, the gain fiber still remains a significant challenge.

Particle swarm optimized neural networks based local tracking control scheme of unknown nonlinear interconnected systems.

In this paper, a local tracking control (LTC) scheme is developed via particle swarm optimized neural networks (PSONN) for unknown nonlinear interconnected systems. With the local input-output data, a local neural network identifier is constructed to approximate the local input gain matrix and the mismatched interconnection, which are utilized to derive the LTC. To solve the local Hamilton-Jacobi-Bellman equation, a local critic NN is established to estimate the proper local value function, which reflects the mismatched interconnection.

We demonstrate that a novel photodetector is constructed by CdS/poly( p-phenylene vinylene) (PPV) homogeneous hybrid nanowire arrays via a simple template-assisted electrochemical codeposition approach.
