Magnetic Pinecone Biochar‐Activated Peroxymonosulfate for Efficient Sulfamethoxazole Degradation: Performance, Mechanism, and Toxicity Analysis

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study successfully prepared magnetic iron/cobalt codoped biochar catalyst (CFSBC) using a one‐step calcination method. The morphology and structure of the material were systematically characterized using SEM, XRD, FTIR, TEM, BET, Raman, VSM, and XPS techniques. The effects of key parameters such as catalyst dosage, peroxymonosulfate (PMS)

Improved Dry‐Pressing Strategy for Fabricating Double‐Sided Rough YSZ Electrolyte Thin Films and Their Performance in Solid Oxide Cells

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study addresses limitations of the conventional dry‐pressing method for electrolyte‐supported films—smooth surfaces, excessive thickness, and fragile supports inducing damage. We propose an innovative camphor–quartz sand composite architecture to construct a five‐layer (camphor/quartz sand/YSZ/quartz sand/camphor) system, enabling thin ...

Effect of Ramped Oxygen Flow During Magnetron Sputtering on the Structural, Optical, and Photoelectrochemical Properties of WO3‐x Thin Films

open access: yesAdvanced Physics Research, EarlyView.
A compositionally graded WO3‐x thin film was engineered through a controlled linear increase of oxygen flow during reactive magnetron sputtering. This deposition strategy yields a gradual transition from an oxygen‐deficient, conductive bottom layer to a more stoichiometric and crystalline surface layer, forming an intrinsic gradient homojunction.

Design of discrete PI‐PR2 controllers for time‐delayed systems using dominant pole placement method

open access: yesAsian Journal of Control, EarlyView.
Abstract This paper presents a new controller structure known as the proportional‐integral proportional‐double‐retarded (PI‐PR2) designed for discrete‐time systems with time delay. The dominant pole placement technique, which is frequently encountered in control systems, is used as the primary design method. The design method starts that dominant poles

Comparative Study of High Voltage Spinel∥Lithium Titanate Lithium‐ion Batteries in Ethylene Carbonate Free Electrolytes

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
FEC and sulfone‐based co‐solvents are investigated as EC‐free electrolytes for LNMO∥LTO cells. FEC‐containing electrolytes demonstrate enhanced electrochemical stability by stabilizing the CEI and SEI layers, mitigating transition metal migration. Conversely, sulfone electrolytes form thinner CEIs and thick, sulfur‐rich SEIs, which are less effective ...

Comparative Investigation of Three Mg Doping Strategies in NMC811 Cathodes for High‐Energy Density Lithium‐Ion Batteries

open access: yesBatteries &Supercaps, EarlyView.
Magnesium (Mg) doping is explored as a stabilization strategy for high‐capacity LiNi0.8Mn0.1Co0.1O2 (NMC811) cathodes. Three doping routes are compared, revealing that solid‐state lithiation delivers the best cycling stability. Operando X‐ray diffraction and electrochemical dilatometry link reduced cation mixing and lattice stabilization to improved ...
