Se‐Vacancy Engineering Enables Dual Electronic and Interfacial Regulation in SnSe2 Nanocatalysts for High‐Performance Lithium–Sulfur Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Se vacancies in SnSe2 induce local electron redistribution and create unsaturated Sn sites, enabling a switch from single‐site to dual‐site adsorption of lithium polysulfides. This structure synergistically enhances redox kinetics, accelerates sulfur conversion, suppresses the shuttle effect, reduces polarization, and significantly improves the ...

Increasing robustness of LSB audio steganography by reduced distortion LSB coding

, 2005
In this paper, we present a novel high bit rate LSB audio watermarking method that reduces embedding distortion of the host audio. Using the proposed two-step algorithm, watermark bits are embedded into higher LSB layers, resulting in increased ...

Implementation of Steganographic Model using Inverted LSB Insertion [PDF]

, 2018
The most important thing in this insecure world is the secrecy of everything. In today’s world, any important data costs more than money. Steganography is the technique in which one can hide data as a secrete in selected image. In case of spatial domain,

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

School Board Elections in England and Wales, 1870–1902: An Electoral Experiment?

History, EarlyView.
Abstract The 1870 Elementary Education Act enabled the creation of school boards in England and Wales. Members were directly elected by the cumulative vote. This method gave each individual voter as many votes as there were seats on a school board, in some cases up to fifteen.
