A Mobile Management System for Reforming Subsidies Distribution in Developing Countries [PDF]

open access: yesJournal of Information & Systems Management Volume 3 Number 4 December 2013, 2014
This paper has a specific objective of being useful for showing how the advances in mobile technologies can help for solving social and political aspects involved in the reform of subsidies in developing countries. It describes the work done to build a mobile-based supportive network that integrates all subsidies partners: governmental, non ...

Polyphenylene‐Based Anion Exchange Membranes with Robust Hydrophobic Components Designed for High‐Performance and Durable Anion Exchange Membrane Water Electrolyzers Using Non‐PGM Anode Catalysts

open access: yesAdvanced Energy Materials, EarlyView.
Terphenyl groups bearing meta‐phenylene and trifluoromethyl substituents as hydrophobic components are incorporated into a quaternized polyphenylene‐based backbone to produce AEMs. The fabricated thin membranes exhibit high ion conductivity, alkaline stability, and mechanical robustness.

For Better and for Worse? On the Transformation of the Finnish Social Assistance Scheme

open access: yesSocial Work and Society, 2020
The recent reform of Finnish social assistance may be described as, in many ways, going against the European tide toward a welfare service state. The reform involved the transfer of the implementation of social assistance from municipal frontline workers

Dynamic Defect Tolerance in Metal Halide Perovskites: From Phenomena to Mechanism

open access: yesAdvanced Energy Materials, EarlyView.
Defect tolerance is the key feature that dominates the high performance of perovskite devices. MHPs exhibit dynamic defect tolerance at practical working condition, which is intrinsically relevant to their soft‐lattice thus mixed ionic‐electronic conduction, and intimately correlated with charge carrier, phonon, lattice, and mobile ions and determine ...

Intensification of Alkaline Electrolyzer with Improved Two‑Phase Flow

open access: yesAdvanced Energy Materials, EarlyView.
Porous nickel‐type electrodes with low tortuosity are fabricated and their role in reducing the capillary pressure, bubble point, and ohmic resistance, which led to lower energy loss and higher current densities and efficiencies is investigated. The cell delivers a current density of 2 A cm−2 at ≈2 V.
