Solar Heating Enhanced Selective Recovery of Metal Ions Through Flowing Electrodes Enabled by Hybrid Carbon Nanostructures

open access: yesAdvanced Functional Materials, EarlyView.
A new electrochemical system based on a microporous hybrid of carbon nanoplatelets and nanotubes to selectively capture Ni2+ from wastewater is constructed. The system temperature rises rapidly when irradiated with sunlight, which enhances the Ni2+ removal rate by 250% and the selectivity by 53%, and the energy consumption is also reduced by 51 ...

Multilayer Soft Photonic Arrays Inspired by Cephalopod Skin for High‐Density, Independent, and Multimodal Actuation

open access: yesAdvanced Functional Materials, EarlyView.
A vertically stacked, DEA‐driven photonic array inspired by cephalopod skin, featuring highly crystalline colloidal crystal gels with vivid color, low FWHM and scalability is presented. The multilayer design removes lateral pixel interference, achieving near‐100% fill factor with fully independent RGB actuation.

Germanane Quantum Dots Promote Metabolic Reprogramming of Immune Cells Toward Regulatory T Cells and Suppress Inflammation In Vitro and In Vivo

open access: yesAdvanced Functional Materials, EarlyView.
Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.

SWAP

Proceedings of the 3rd International Conference on High Performance Compilation, Computing and Communications, 2019
Network traffic measurement is a fundamental part of many network applications, such as DDOS detection, capacity planning, and quality-of-service improvement. To achieve this, we need to count the number of packets passed during a past time interval. Traditionally, switches sample the packets and send them to the CPU for analysis.

Swaps and Swap Derivatives

1993
The swap in its simplest form can be described as a periodic exchange (or ‘swap’) of payments between two counterparties for a specified period of time; the exchange is generally based on interest rates, currency rates or commodity prices. The actual exchange of payments is governed by a contractual agreement between the participants and is reflected ...

2007
A swap is a derivative, where two counterparties exchange one stream of cash flows against another stream. These streams are called the legs of the swap. The cash flows are calculated over a notional principal amount swaps are often used to hedge certain risks. For instance interest rate risk. Another use is speculation. Swaps are over the counter (OTC)
