Rapid Cycling and Exceptional Yield in a Metal-Organic Framework Water Harvester. [PDF]

open access: yes, 2019
Sorbent-assisted water harvesting from air represents an attractive way to address water scarcity in arid climates. Hitherto, sorbents developed for this technology have exclusively been designed to perform one water harvesting cycle (WHC) per day, but ...

High‐Concentration Mesogen‐Assisted Exfoliation of Low‐Dimensional Nanomaterials for Achieving Ultralow‐Temperature Actuations of Liquid Crystal Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

Beyond Polarity: Negotiating a Hybrid State in Somaliland Jenseits der Polarität: Das Aushandeln eines hybriden Staates in Somaliland

open access: yesAfrica Spectrum, 2010
Many African states struggle to reconcile traditional social institutions with the precepts of nation-state democracy within colonially defined borders. Since the 1991 fall of the dictatorial Somali regime of Siyaad Barre, Somaliland has gradually pieced

The time course of altered brain activity during 7-day simulated microgravity

open access: yesFrontiers in Behavioral Neuroscience, 2015
Microgravity causes multiple changes in physical and mental levels in humans, which can induce performance deficiency among astronauts. Studying the variations in brain activity that occur during microgravity would help astronauts to deal with these ...

Dynamic Control of Synaptic Plasticity by Competing Ferroelectric and Trap‐Assisted Switching in IGZO Transistors with Al2O3/HfO2 Dielectrics

open access: yesAdvanced Functional Materials, EarlyView.
A frequency‐tunable ferroelectric synaptic transistor based on a buried‐gate InGaZnO channel and Al2O3/HfO2 dielectric stack exhibits linear and reversible weight updates using single‐polarity pulses. By switching between ferroelectric and trap‐assisted modes depending on input frequency, the device simplifies neuromorphic circuit design and achieves ...

Fernando Henrique Cardoso: The Astuzia Fortunata of Brazil’s Sociologist-President La Astuzia Fortunata de Fernando Henrique Cardoso

open access: yesJournal of Politics in Latin America, 2009
Even in the Renaissance, there were not that many Renaissance men. But if it was hard to live many lives in one even for the best placed of Renaissance Europe it is surely harder in contemporary republican Brazil. And yet Fernando Henrique Cardoso or FHC

Multicriterial ranking approach for evaluating bank branch performance [PDF]

open access: yes, 2004
14 ranking methods based on multiple criteria are suggested for evaluating the performance of the bank branches. The methods are explained via an illustrative example, and some of them are applied to a real-life data for 23 retail bank branches in a ...

3D Digital Light Processing of Redox‐Active Polymers for Electrochemical Applications

open access: yesAdvanced Functional Materials, EarlyView.
3D printing of electrochemically switchable conducting polymers is achieved by Digital Light Processing of redox‐active carbazole‐based polymer materials. Complex 2D and 3D architectures including dot arrays and pyramids clearly show the potential for novel 3D switchable electrochemical devices for sensors, electrochromic displays as well as 3D printed

From Rebels to Rulers and Legislators: The Political Transformation of the Free Aceh Movement (GAM) in Indonesia

open access: yesJournal of Current Southeast Asian Affairs, 2010
On 15 August 2005, when the Republic of Indonesia and the Free Aceh Movement (Gerakan Aceh Merdeka, GAM) signed the Memorandum of Understanding (MoU) in Helsinki, Finland, it was considered yet another uncertain attempt at putting an end to Indonesia’s ...
