Effect of the Fe Catalyst on Formation Pathways of Fractionated Bio-Oils from Solvent-Modulated Co-hydrothermal Liquefaction

Abstract Solvent modulation synergized with Fe catalysis offers a promising strategy for regulating fractionated bio-oil formation during co-hydrothermal liquefaction. Herein, corn stover (CS) and spirulina (SP) were used as feedstocks in this study. An ethanol-water co-solvent s...

A Type-I/II Photosensitizer with Cell Death Self-Reporting for Ferroptosis-Potentiated Photodynamic Theranostics against Large Tumors

Abstract Photodynamic therapy (PDT) with ferroptosis induction is a promising antitumor strategy, yet its efficacy is compromised by conventional photosensitizers limited to single-pathway ROS generation, particularly in large tumors. Herein, a series of D−A−D AIE photosensitizer...

Poly(propylene carbonate- co -thioether- co -ether) Terpolymer and Its Application as a Solid-State Electrolyte

Abstract Sulfur-containing polymers, especially those with sulfur in the main chain, have attracted significant interest owing to their diverse structures and unique properties, making them promising candidates for solid-state electrolytes. However, their controllable synthesis i...

Diamond-based deep ultraviolet vortex beam generation with suppressed higher-order diffractions

Optical vortices (OVs) with unique singular phase and orbital angular momentum are widely used in various applications including particle manipulation, microscopy, and imaging scenarios. Regardless, the undesired higher-order foci introduced by the conventional vortex lens such a...

Stabilizing Water Molecules in Hydrogel Electrolytes Enables 2.8 V‐Class Purely Aqueous Zn–Li Hybrid Batteries

ABSTRACT Currently, reported high‐voltage aqueous zinc batteries generally operate below 2.0 V. Achieving a discharge plateau/average operating voltage exceeding 2.0 V typically requires charging voltages above 2.5 V; however, the limited electrochemical stability of water molecu...

Energy dependence and the differential pass-through of oil price shocks to inflation: evidence from 72 countries

International oil price fluctuations are an important source of external inflation pressure, but their domestic effects vary across economies depending on exposure to imported energy costs. This study examines whether energy dependence systematically explains heterogeneous inflat...

Controllable AI modeling of northern and southern timbercraft convergence in Qing interior canopies

This study examines interior canopies from the Qianlong–Jiaqing era (1736–1820) of the Qing dynasty to model northern–southern timbercraft convergence through controllable AI generation. We constructed northern official and southern garden semantic lexicons, trained dual LoRA mod...

Identifying recreation priority development zones in global wetland cities under wetland conservation considerations

Balancing recreation and wetland conservation requires identifying where recreational opportunities can be developed with limited ecological disturbance. Taking 43 globally Ramsar-certified Wetland Cities as the study area, this study integrates multi-source remote-sensing and ge...

A novel decoupled identification-and-tracking framework for photovoltaic global maximum power point tracking under complex shading scenarios

Partial shading in photovoltaic (PV) arrays introduces nonlinearities that create multiple local maxima in the power–voltage curves, often causing conventional and metaheuristic trackers to converge on suboptimal peaks. To address this, this paper proposes a novel physics-informe...
