Isolated and Paired Metal Sites in Zeolites Using Solid‐State Ion Exchange
Angewandte Chemie, Volume 137, Issue 23, June 2, 2025.Transition metal ions housed in the zeolitic micropore are broadly applied in catalysis. These model active sites provide a link between homogeneous, enzyme, and solid catalysts. The synthetic strategy used to generate these cationic sites has a significant influence on the catalytic activity.

Cost‐Effective Winner‐Take‐All Approach for Comparing Multi‐Output Neural Networks
IET Circuits, Devices &Systems, Volume 2026, Issue 1, 2026.This work focuses on designing a winner‐take‐all (WTA) algorithm using digital circuits, rather than the more commonly used analog circuits. In this context, neurons are represented as digital bits, similar to those in convolutional neural networks (CNNs) and weightless neural networks (WNNs). The proposed WTA circuit compares the most significant bits

Proton‐linked effects on the axial coordination in ferric and ferrous horse heart cytochrome c
Protein Science, Volume 34, Issue 11, November 2025.Abstract The effect of pH (between pH 7.0 and 0.0) on the spectroscopic properties of ferric and ferrous derivatives of horse heart cytochrome c (hhcytc‐Fe(III) and hhcytc‐Fe(II), respectively) in 1.0M phosphate buffer is reported. This study further deepens the investigation of spectroscopic properties of a heme‐protein to very low pH (i.e., pH ≈ 0 ...

Optimized design of power loops for virtual synchronous generator to enhance transient stability
IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.Abstract Virtual synchronous generator (VSG) control is an attractive method to solve the stability issues of future renewables (e.g. photovoltaic [PV])‐dominated power system. Unfortunately, a VSG is prone to transient instability under grid faults, and the existing work ignores the instability issues caused by current limitation and reactive power ...

Limit Cycle on the Forced Vibrations Oscillator with a Time‐Varying Mass
International Journal of Differential Equations, Volume 2024, Issue 1, 2024.In this paper, a forced vibration caused by drag and lift forces with time‐varying mass is studied. The construction of the model is conducted by adding impact force to the previous model. The periodicity of the solution is yet known. Hence, the model is seen as a perturbation problem.

Height Control of Supersonic Sea‐Skimming Missiles Based on Online Parameter Identification
International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.This paper presents a height control approach employing real‐time parameter identification for supersonic sea‐skimming missiles. Firstly, an integrated identification technique based on the Unscented Kalman filter was established for supersonic cruise missiles.

International Journal of Aerospace Engineering, Volume 2024, Issue 1, 2024.Online identification of aerodynamic parameters of experimental rockets was completed based on unscented Kalman filtering (UKF). Numerical simulation, hardware‐in‐the‐loop (HIL) simulation, and flight tests were conducted. The identification error of aerodynamic force in numerical simulation and HIL simulation is within 2%.

The Mechanism and New Strategy on Competitive Release Effect of β‐Cyclodextrin Inclusion Complexes
Journal of Chemistry, Volume 2024, Issue 1, 2024.Competitive release is an important release pattern of β‐cyclodextrin (β‐CD) inclusion complexes. Releasing flavor by absorbing harmful molecules is an ideal situation. Thus, two inclusion complexes, phenethyl alcohol β‐CD inclusion (PACD) and phenol β‐CD inclusion (PNCD), were prepared and their combining capacity was studied.
