Two lower-oxidation state uranium cations can be readily combined in a robust, yet flexible and derivatisable, tetraaryloxide ligand framework, affording a new platform at which to use the multi-electron reductive capacity of the two actinide centres.

Software flexibility is one of the properties that indicate if the software is easy to change. Flexible software can easily adapt to user requirement and/or environment changes during the software development period or after the software is deployed. In this paper, we introduce two new concepts, flexible change and FleXible Point( FXP). Associated with the flexible point, a set of flexibility i...

BACKGROUND Despite increasing investment in health research capacity strengthening efforts in low and middle income countries, published evidence to guide the systematic design and monitoring of such interventions is very limited. Systematic processes are important to underpin capacity strengthening interventions because they provide stepwise guidance and allow for continual improvement. Our ob...

Lithium-air batteries (LABs) are expected to provide a cell with a much higher capacity than ever attained before, but their prototype cells present a limited areal cell capacity of no more than 10 mAh cm-2, mainly due to the limitation of their air electrodes. Here, we demonstrate the use of flexible carbon nanotube (CNT) sheets as a promising air electrode for developing ultra-high capacity i...

This article develops a model and analysis to provide insight into two effective remedies to increase supply chain resilience: (i) contracting with a secondary flexible backup supplier; and (ii) monitoring primary suppliers to obtain disruption risk information. To investigate the true value of these strategies, an analysis is performed under imperfect information concerning the disruption risk...

the latest instrument in islamic financial market is sukuk securities.   sukuk is a flexible stock securities that can meet the financial needs of firms in the capital markets. however, sukuk is considered as an alternative investment securities for bonds that receive usury which is forbidden in islam. the growth of  sukuk market in recent years, mainly due to its role in monitoring and control...

The extraction of two Li-ions per formula unit from the Li-rich cathode materials is still far reality due to intense structural changes that occur in this type of...

Flexible lithium-ion batteries are necessary for powering the next generation of wearable electronic devices. In most designs, the mechanical flexibility of the battery is improved by reducing the thickness of the active layers, which in turn reduces the areal capacity and energy density of the battery. The performance of a battery depends on the electrode composition, and in most flexible batt...

The drive to reduce reliance on fossil fuel generation in meeting power system demand is encouraging network operators to develop novel methods of making greater use of available network capacity whilst maintaining stability and security. Challenges relating to network stability are particularly acute on islanded networks. The Northern Isles New Energy Solutions (NINES) project is implementing ...
