Advanced Sustainable Systems, EarlyView.This study enhances biobassed, biodegradable polyhydroxybutyrate (PHB)s strength and ductility by reinforcing it with polyvinyl alcohol (PVA)‐coated cotton fibres and further improving interfacial bonding through maleic anhydride (MA) grafting. In addition to mechanical performance, the approaches significantly improve the gas barrier properties of the

Agglomeration economies in the Netherlands [PDF]
In this paper we measure the strength of agglomeration economies on the basis of Dutch regional data. The drift to the city has been going on for hundreds of years. As a result, most economic activity is concentrated in small geographical areas.

Advanced Science, EarlyView.This study presents a rational design of hetero‐atom distribution within 2D‐COFs for selective electrochemical lithium extraction through capacitive deionization. The COF's high surface area and charge density facilitate effective lithium‐ion capture, offering a scalable and sustainable approach for lithium recovery from complex brine solutions ...

The Importance of Increasing Returns to Scale in the Process of Agglomeration in Portugal: A Non-linear Empirical Analysis [PDF]
arXiv, 2011 With this work we try to analyse the agglomeration process in the Portuguese regions, using the New Economic Geography models. In these models the base idea is that where has increasing returns to scale in the manufactured industry and low transport costs, there is agglomeration. Of referring, as summary conclusion, that with this work the existence of

Agglomeration economies and entrepreneurship: testing for spatial externalities in the Dutch ICT industry [PDF]
Although there is growing evidence on the role of agglomeration economies in the formation and growth of firms, both the concepts of agglomeration economies and entrepreneurship tend to be ambiguously defined and measured in the literature. In this study,

Is there an agglomeration economy in Eastern Russia?
Area Development and PolicyThis analysis disproves the widespread opinion that, in Eastern Russia, where the settlement structure and transport network are less dense, agglomeration effects are either absent or negligible. Econometric estimates have revealed a significant contribution of agglomeration economies to the efficiency of companies mainly in the southern regions ...

Advanced Science, EarlyView.The highly conductive IZO/Ag/IZO multilayer transparent electrode is successfully fabricated through flashlight annealing (FLA) process. A transient thermal effect of FLA maintains the continuous Ag interlayer and improves the crystallinity of the sandwich IZO layers. This combination increases both electric conductivity and optical transmittance.
