Leidenfrost‐Assisted Synthesis of Indium‐Substituted Mixed Phosphate Cathodes with Superior Cycling Stability and Enhanced Sodium Storage Kinetics

open access: yesSmall, EarlyView.
The work presents a Leidenfrost‐assisted synthesis as a low‐cost and scalable approach for designing In3+‐doped mixed phosphate ([PO4]3−‐[P2O7]4−) cathodes. The optimized cathode composition exhibits exceptional electrochemical performance, with a specific capacity of 129.3 mAh g−1 at 0.05 C, corresponding to an energy density of ∼$\sim $359 Wh kg−1 ...

Versatile electric fields for the manipulation of ultracold NaK molecules

open access: yesNew Journal of Physics, 2016
In this paper, we present an electrode geometry for the manipulation of ultracold, rovibrational ground state NaK molecules. The electrode system allows to induce a dipole moment in trapped diatomic NaK molecules with a magnitude up to 68% of their ...

An Efficient Network Coding based Retransmission Algorithm for Wireless Multicasts

open access: yes, 2010
Retransmission based on packet acknowledgement (ACK/NAK) is a fundamental error control technique employed in IEEE 802.11-2007 unicast network. However the 802.11-2007 standard falls short of proposing a reliable MAC-level recovery protocol for multicast

Prussian Blue Analogues for Non‐Aqueous Sodium‐Ion and Potassium‐Ion Batteries: The Landscape From Lab‐Scale Optimizations Toward Practical Applications

open access: yesSmall, EarlyView.
Prussian blue analogues (PBAs) are scalable cathode materials for non‐aqueous sodium‐ (SIBs) and potassium‐ion batteries (PIBs). This review links crystal chemistry, defect control, and particle engineering with electrochemical performance, highlighting how synthesis, crystal water, and interfacial stability jointly determine practical energy density ...

On conjugate heat transfer in microchannel heat sinks

open access: yesInternational Journal of Thermofluids
This work aims to study the anisotropic thermal impacts of employing liquid metal fluids including Na and NaK as coolants in two metallic microchannel heat sinks. The two studied microchannel heat sinks have aspect ratios of 1 and 2 while their hydraulic

Six-dimensional potential energy surface for NaK–NaK collisions: Gaussian process representation with correct asymptotic form [PDF]

open access: yesThe Journal of Chemical Physics, 2019
Constructing accurate global potential energy surfaces (PESs) describing chemically reactive molecule-molecule collisions of alkali metal dimers presents a major challenge. To be suitable for quantum scattering calculations, such PESs must represent accurately three- and four-body interactions, describe conical intersections, and have a proper ...

Patient‐reported outcomes, postoperative pain and pain relief after day‐case surgery (POPPY): baseline data from day surgery practice in the UK

open access: yesAnaesthesia, EarlyView.
Summary Introduction Most patients undergoing elective surgery in the UK are discharged from hospital on the same day. Despite this, there is a lack of UK patient‐centred outcome measures relating to quality of recovery, pain and analgesic use. The POPPY study was a UK‐wide prospective, observational study measuring short‐ and longer‐term patient ...
