Na5FeS4 as High‐Capacity Positive Electrode Active Material for All‐Solid‐State Sodium Batteries

Batteries &Supercaps, EarlyView.
All‐solid‐state sodium cells using Na5FeS4, synthesize through a simple and scalable process using sodium polysulfides, as a positive electrode active material exhibit a high reversible capacity of 480 mAh g−¹, which is attributed to the sufficiently high ionic conductivity of the active material and the maintenance of the active material/solid ...

Investigation of Degradation Pathways in Fluoroethylene Carbonate Based Electrolytes via Chromatographic Techniques

Batteries &Supercaps, EarlyView.
In this article, decomposition products of the lithium ion battery electrolyte component fluoroethylene carbonate (FEC) are examined in varying amounts by means of liquid chromatography coupled to high‐resolution accurate mass spectrometry. Based on identified degradation products, FEC degradation mechanism is further postulated and confirmed, whereby ...

Further experimental results on the structure and acoustics of turbulent jet flames [PDF]

, 1975
The structure of open turbulent jet flames is experimentally studied in the context of their noise emission characteristics. The differences between premixed and (co-flow) non-premixed flames are explored.

Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Multifunctional Design of Solid Polymer Electrolytes: Paving the Way for High‐Performance All‐Solid‐State Batteries

Carbon Energy, EarlyView.
This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

Multiple Dimerization Modes in Thiocarboxylate Paddlewheel Complexes: A Comprehensive View of Energy Landscapes from DFT Calculations and Statistics

Chemistry – A European Journal, EarlyView.
Staggered, square, and heavily bent dimers occur in the five known solvatomorphs of paddlewheel (PW) complex [PtVO(SOCPh)4]. These and other structural motifs are well within energetic reach due to the shallow potential energy surface that guides dimerization and are included in a revised classification of available structural data on heterobimetallic ...

Regio‐ and Diastereoselective C–C Silylation of Cyclopropyl Acetates Harnessing Fluorinated Poly(pyridyl)Borate Rhodium Catalysts

Chemistry – A European Journal, EarlyView.
Fluorinated poly(pyridyl)borates have been utilized to stabilize rhodium‐diene complexes and as supporting ligands in rhodium‐catalyzed redox‐neutral C–C silylation of cyclopropyl acetates, producing silicon‐containing heterocyclic products, dioxasilolanes.

Characteristics of concurrent flame spread over convex charring materials

Case Studies in Thermal Engineering
In real forest fire scenarios, there are a large number of convex and concave terrains at the junction of flat land and slopes. In this paper, a typical charring material, kraft paper, is selected as the experimental sample, and the variation law of key ...

Variable Temperature Studies of Two Calcium Uranates α‐Ca3UO6 and Ca2UO5

Chemistry – A European Journal, EarlyView.
The structures and thermal responses of the calcium uranates α‐Ca3UO6 and Ca2UO5 were investigated using in situ synchrotron x‐ray diffraction and neutron powder diffraction. Despite the very similar chemical compositions, the structural response of the two calcium uranates is shown to be complex and varied.

Turbofan forced mixer lobe flow modeling. Part 3: Application to augment engines [PDF]

Military engines frequently need large quantities of thrust for short periods of time. The addition of an augmentor can provide such thrust increases but with a penalty of increased duct length and engine weight.
