Heterogeneous Agglomeration [PDF]

open access: yesReview of Economics and Statistics, 2017
Many prior treatments of agglomeration explicitly or implicitly assume that all industries agglomerate for the same reasons. This paper uses UK establishment-level coagglomeration data to document substantial heterogeneity across industries in the microfoundations of agglomeration economies.

Natural Agglomeration [PDF]

open access: yesSSRN Electronic Journal, 2003
This paper considers the racetrack economic approach, where manufacturing activities are distributed continuously. We seek constant-access equilibria and show that smooth equilibrium distributions are always unstable for almost all transport cost functions, whereas agglomeration in 1 or 2 atomic cities is stable for any economic parameters given ...

Is Agglomeration Desirable? [PDF]

open access: yesAnnals of Economics and Statistics, 2009
By introducing heterogeneity between high-skilled mobile and low-skill immobile workers in a model with land rent and commuting costs we develop a new model in the field of the new model in the field of the new economic geography. This model, which can reveal a dispersion-agglomeration-dispersion configuration when trade gets freer, is used to compare ...

A novel Cu/HAP@sBC composite as a persulfate activator for the removal of 2,4,6-trichlorophenol

open access: yesCatalysis Communications, 2023
As a typical chlorophenol, 2,4,6-trichlorophenol (2,4,6-TCP) is highly toxic and difficult to degrade. Here, we prepared a novel material (Cu/HAP@sBC) by combining copper-based hydroxyapatite with biochar, which removes 2,4,6-TCP via activated persulfate

Bio-sorption for tannery effluent treatment using eggshell wastes; kinetics, isotherm and thermodynamic study

open access: yesEgyptian Journal of Petroleum, 2020
Since, cobalt, zinc, mercury and lead ions are high toxic heavy metals; this work aims to investigate the efficiency of eggshell as a low cost sorbent for their ions from aqueous solution.

Improved stability and promoted activity of laccase by One-Pot encapsulation with Cu (PABA) nanoarchitectonics and its application for removal of Azo dyes

open access: yesEcotoxicology and Environmental Safety, 2022
Immobilization of laccase helps protect the laccase and realizes repeated use. However, excessive encapsulation protection will also limit the release of laccase activity.
