Single‐atom catalysts (SACs) composed of atomically dispersed metal‐active sites embedded in supporting substrates are attracting increasing attention in liquid‐phase selective oxidation reactions with joint merits of both advanced catalyti...

A hash-neighborhood-search-network-coding based opportunistic relay retransmission approach

In wireless multicast networks，it is rarely concerned that there may be certain receiving nodes which have better quality links both to the source node and to the other receiving nodes. A novel hash-neighborhoodsearch-network-coding based o...

Six‐face cubical key encryption and decryption based on product cipher using hybridisation and Rubik's cubes

This paper deals with the novel approach to generate cubical key that symbolises the message and key in six‐face cubical structure. The cubical message is hybridised to generate the cipher in the encryption. Hybridisation of cubes is perfor...

Sustainable re-use of waste glass, cement and lime treated dredged material as pavement material

The amount of waste materials such as dredged materials (DM) and waste glass (WG) have been growing exponentially since the middle of the 20th century. The most important problem created by them is the lack of space to be used for storage b...
