A Hexadecacationic Metal–Organic Cage for Anchoring Sulfonates: High‐Order Binding of Di‐ and Trisulfonates and High‐Performance Removal of Perfluorosulfonates from Water

open access: yesAdvanced Science, EarlyView.
Developing synthetic hosts that can bind sulfonate anions or sequester perfluorosulfonates is crucial in biological and environmental sciences. Here, a Zr‐based metal–organic cage (1) integrating electron‐deficient tripyridinium panels is designed and synthesized.

Dantzig-Wolfe decomposition and branch-and-price solving in G12 [PDF]

open access: yesConstraints, 2009
The G12 project is developing a software environment for stating and solving combinatorial problems by mapping a high-level model of the problem to an efficient combination of solving methods. Model annotations are used to control this process. In this paper we explain the mapping to branch-and-price solving.

Non-local Andreev reflection under ac bias

open access: yes, 2009
We theoretically analyze non-local electron transport in multi-terminal normal-metal-superconductor-normal-metal (NSN) devices in the presence of an external ac voltage bias.

How to Test Triboelectric Nanogenerators: Key Factors for Standardized Performance Evaluation

open access: yesAdvanced Energy Materials, EarlyView.
This paper is a guide on how to test triboelectric nanogenerators (TENGs) so that results can be reliably compared across different laboratories. It explores the many factors (fabrication, mechanical, electrical, and environmental) that can affect TENG testing results and provides recommendations for best practice in testing and performance evaluation.

MANFAAT MOTIVASI BELAJAR BERBASIS KEARIFAN LOKAL G12 [PDF]

open access: yesEduHumaniora | Jurnal Pendidikan Dasar Kampus Cibiru, 2019
Abstract: Learning is an obligation as well as a spiritual need of human. Especially in the global era that all sophisticated has given various consequences and influence both positive and negative. The positive value must provide good for learners but the negative value with a series of moral decadence cases such as cheating in learning activities ...

The Role of Temperature in the occurrence of some Zeno Phenomena

open access: yes, 2012
Temperature can be responsible for strengthening effective couplings between quantum states, determining a hierarchy of interactions, and making it possible to establish such dynamical regimes known as Zeno dynamics, wherein a strong coupling can hinder ...

Entanglement of two qubits mediated by one-dimensional plasmonic waveguides [PDF]

open access: yes, 2011
We investigate qubit-qubit entanglement mediated by plasmons supported by one-dimensional waveguides. We explore both the situation of spontaneous formation of entanglement from an unentangled state and the emergence of driven steady-state entanglement ...

The impact of the Russia–Ukraine war on stock prices, profits and perceptions in the food supply chain

open access: yesAgribusiness, EarlyView.
Abstract The Russian invasion of Ukraine in February 2022 had profound consequences for the global economy. As both countries are major commodity exporters, the food value chain was also affected. This study investigates the impact of the invasion on stock prices, profitability and sentiments of agribusinesses along the food supply chain by using an ...

Temperature and magnetic-field dependence of the quantum corrections to the conductance of a network of quantum dots

open access: yes, 2008
We calculate the magnetic-field and temperature dependence of all quantum corrections to the ensemble-averaged conductance of a network of quantum dots. We consider the limit that the dimensionless conductance of the network is large, so that the quantum
