Asymmetric Active Center Triggers Side‐On Photo‐Fenton‐Like Reaction Through Polar Charge Transfer and Self‐Adapting Sulfur Vacancies

Advanced Science, EarlyView.
The Cu‐Zn3In2S6 photocatalyst (Cu‐ZISV) with asymmetric Cu‐SV‐Zn sites was designed and synthesized to boost peroxymonosulfate (PMS) activation kinetics. The side‐on photo‐Fenton‐like reaction by the asymmetric Cu‐SV‐Zn site accelerated PMS activation and pollutant degradation, and the first‐order kinetic constant of Cu‐ZISV increased by 4.87 times ...

Mobility patterns and characterisation of functional urban areas in low-density regions: Castilla-La Mancha (Spain) [PDF]

, 2010
The spatial research of labour markets has been often carried out from a local perspective, analysing their characteristics in the urban and metropolises frameworks. The spatial structures have been increasing their complexity because of several reasons,

Multifunctional Tailoring of Fertilizer Composites Directly Derived From Phosphate Rock

Advanced Science, EarlyView.
A novel phosphorus‑sulfur mixed acid with urea (PSU) activation system converts low‑grade phosphate rock (LPR) into multifunctional fertilizer composites (MFCs). MFCs feature porous structures, high nutrient‑activation efficiency, superior slow‑release, and enhanced crop growth, offering a sustainable solution for integrated nutrient management and ...

PROBLEMS OF URBAN GREEN AREAS AND THEIR SOCIAL FUNCTION

JOURNAL OF ARCHITECTURE AND URBANISM, 2006
The town is a complicated system the main components of which are the community and its environment. Therefore, town planning and formation of green area should be performed taking into consideration the community’s activities and needs. Favorable conditions must be created for people to live, work, study and rest.

A Novel Metal Foam‐Supported Solid Oxide Fuel Cell With High Specific Power

Advanced Science, EarlyView.
Solid oxide fuel cells (SOFCs) employing metal foam supports with an ultrahigh porosity of 90% and average pore size of 100 µm are successfully fabricated. The metal foam architecture significantly enhances gas diffusion coefficients, effectively reducing concentration polarization while simultaneously decreasing areal mass.

From the Gut to the Brain: Microplastic‐Associated Neurovascular Dysfunction and Implications for Stroke Risk

Advanced Science, EarlyView.
Chronic oral exposure to microplastics may disrupt gut microbiota homeostasis and intestinal barrier integrity, potentially engaging the gut–brain axis and systemic inflammatory responses. These alterations may be associated with impaired blood–brain barrier function, cerebral microvascular dysfunction, and enhanced endothelial inflammation, pro ...
