Compartmentalized Homeostasis Drives High Bamboo Forest Productivity under Nutrient Imbalance
Advanced Science, EarlyView.This study reveals how Moso bamboo achieves high productivity despite nutrient‐poor soils. It employs a unique strategy, maintaining strict nutrient balance in its leaves while using woody tissues as flexible storage reservoirs. This compartmentalized mechanism buffers the plant from soil phosphorus limitation and microbial competition, resolving the ...

Modeling Recreational Amenities in an Urban Setting: Location, Congestion, and Substitution Effects [PDF]
In this article, we introduce a recreational amenity—a greenbelt park—into a simple urban economic model. For multiple possible park placements, we solve for the associated equilibrium urban structure, including the equilibrium rent gradient, city ...

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 ...

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 ...

Inequality in Vietnamese Urban-Rural Living Standards, 1993-2006 [PDF]
Using data from five waves of the Vietnam Household Living Standard Survey, we find evidence of significant urban-rural expenditure inequality. Urban-rural inequality in Vietnam increased dramatically from 1993 to 1998, and peaked in 2002 before reducing

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.

Search, Wage Posting, and Urban Spatial Structure [PDF]
We develop an urban-search model in which firms post wages. When all workers are identical, there is a unique wage in equilibrium even in the presence of search and spatial frictions. This wage is affected by spatial and labor costs.
