Synthesis and Characterization of Monodisperse Sulfonic Acid‐Functionalized Hollow Polymer Microspheres Using Precipitation Polymerization as Recyclable Solid Acid Catalysts

Macromolecular Rapid Communications, EarlyView.
Monodisperse sulfonic acid‐functionalized hollow polymer microspheres were prepared via precipitation polymerization using a cleavable phenylsulfonate‐containing styrene dimer. Core‐shell particles were converted into hollow structures through selective core cleavage and functionalization.

Reducing Ammonia Emission during Food Waste Composting and Enhancing Compost Quality Using Different Additives

ChemistryOpen, EarlyView.
This research successfully reduces the ammonia emission by 45% and achieves good quality compost using additives (lactic acid or acetic acid) and bulking agents (mature compost or sawdust). The study supports Sustainable Development Goals 12 and 13 by promoting waste‐to‐resource option.

Interactive effects of microplastics and arbuscular mycorrhizal fungi on grassland communities

PLANTS, PEOPLE, PLANET, EarlyView.
Grassland plant communities contribute significantly to global biodiversity but face numerous man‐made pressures which may interfere with their ecological functions. One such pressure receiving increasing scientific, political, and public attention is microplastic pollution.

Gradient‐ and Newton‐Based Unit Vector Extremum Seeking Control

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper proposes new methods for stable and efficient convergence in multivariable extremum seeking control (ESC) using sliding mode techniques. Inspired by classical sliding modes and finite‐time control, the approach integrates these ideas into gradient‐ and Newton‐based ESC schemes with sinusoidal perturbations.

Hexapod Locomotion Across Structured and Unstructured Terrains: A Data‐Driven Review of Modeling, Control, and Validation

Journal of Field Robotics, EarlyView.
ABSTRACT The design of a hexapod is complex and requires integration between kinematic models, control systems, and sensing. Existing literature has reviewed these sub‐systems in isolation. Since 2021, there has been no review of the field despite significant advancements in soft soil, lunar traversal, and artificial intelligence.
