Root‐Applied Phyto‐Courier Loaded With Rutin Translocates to Aerial Tissues Inducing Molecular and Anatomical Changes in Cannabis sativa Under Salinity

open access: yesNano Select, Volume 6, Issue 12, December 2025.
The rutin‐loaded phyto‐courier formulation was taken up by hemp roots and translocated to aerial organs, inducing changes in the metabolome and gene expression. Under salt stress, the formulation preserved the leaf palisade layer and promoted the development of bast fibers in the stems.

Topological carbon allotropes: paradigm shift for materials innovation

open access: yes, 2019
Topology is a central concept of mathematics, which allows us to distinguish two isolated rings with linked ones. In material science, researchers discovered topologically different carbon allotropes in a form of a cage, a tube, and a sheet, which have ...

Benzene [PDF]

open access: yesACM Transactions on Architecture and Code Optimization, 2018
This article proposes Benzene, an energy-efficient distributed SRAM/STT-RAM hybrid cache for manycore systems running multiple applications. It is based on the observation that a naïve application of hybrid cache techniques to distributed caches in a manycore architecture suffers from limited energy reduction due to uneven utilization of scarce SRAM ...
