About Cover

The cover photo of July 2019 issue is dedicated to the 41st anniversary of the first reported synthetic approach of dendritic hyperbranched structure. The cover photo adopted from the Valer et al., where they reported the preparation of dendritic hyperbranched copolymers based on bis(hydroxyl methyl) propionic acid polyester and studied the architecture - behavior - properties relationship. Dendritic structures are known for their perfect chemical definition, highly dense structure, and a well-defined number of surface functionalities. The soft multifunctional modifications could be compliant to valuable flexibility for embedding different chemical moieties on the surface either within the structure or at the core.

Abstract

The unique electronic and optical properties of recently discovered two-dimensional (2D) crystals, such as graphene, graphene oxide, molybdenum disulphide etc., demonstrate their enormous potential in creating ultrahigh density electronics for image recognition systems and information storage. Synapse-like memristive heterostructures are considered as a new type of electronic switches with extremely low power consumption and footprint that can be used to overcome the limit of current CMOS technology. Memristors with a floating photogate, called photomemristors, based on graphene and MoS2, are considered. Photocatalytic oxidation of graphene is considered as an effective method for creating memristive heterostructures with photoresistive switching for non-volatile electronic memory of ultrahigh density for the formation of self-assembled nanoscale memristive elements interfacing with neural networks. 2D photomemristors with a floating photogate exhibit multiple states that can be monitored over a wide range of electromagnetic radiation and can be used in neurohybrid systems for image processing and pattern recognition, as well as for selective manipulation of neurons by light.  © VBRI Press.
