Back cover image: Featuring isolated dispersed metal atoms on a substrate, single atom catalysts (SACs) have emerged as new frontier in lithium-sulfur battery (LSB) realm thus far. In the tutorial review (number: 10.1002/cey2.286), Song et al. systematically summarized design principle, typical fabrication of SACs and their latest advancements manipulating sulfur lithium evolutions. Further, in...

it is necessary to determine the amount of chilling requirement of present cultivars and also to produce new low chill cultivars through breeding programs because of the global warming phenomenon and tendency to grow temperate fruit in warm climate. in this study, the amount of chilling requirement in ‘askari’, ‘rotaby’, ‘yaghuty’, ‘rish baba’ and ‘monaga΄ were evaluated. uniform cuttings of me...

solving a large sparse set of linear equations is of the problems widely seen in every numerical investigation in the entire range of engineering disciplines. employing a finite element approach in solving partial derivative equations, the resulting stiffness matrices would contain many zero-valued elements. moreover, storing all these sparse matrices in a computer memory would slower the compu...
