"Advanced steganographic approach for hiding encrypted secret message in LSB,LSB+1,LSB+2 and LSB+3 bits in non standard cover files"

International Journal of Computer Applications, 2011
In digital steganography normally image, audio or video files are the standard cover files or the host files for embedding secret message such as text, image, audio or video. Nath et al.(2) explored the standard method for hiding secret message inside standard cover files such as image, audio or video files. In the present work we have shown how we can

A Holistic Stabilization of the Anode in Lithium‐Sulfur Batteries Through a Ternary Alloy Fusion

Advanced Functional Materials, EarlyView.
LiTeAl anodes fabricated through a scalable thermal fusion technique holistically addresses the stability issues faced by lithium‐metal anodes in lithium–sulfur batteries. Aluminum forming a skeletal network with lithium suppresses dendrite growth and enhances energy density, while tellurium forming a robust SEI facilitates Li+‐ion flow.
