Recent Advances in Carbon Material‐Based Multifunctional Sensors and Their Applications in Electronic Skin Systems

Graphene, a two-dimensional carbon material, has attracted tremendous research interest in recent years due to its exceptional properties, such as excellent electrical, mechanical and thermal properties. Meanwhile, various kinds of novel functional materials based on Graphene oxide are employed in different fields like solar cell, sensor and catalysis. With the increasing number of catalysts during synthesizing graphene-based composites, the development of catalysis science and technology will surely be promoted. This paper reviews recent advances in the preparation and structure of graphene oxide, especially its applications in catalysis fields.

Major Progress

The use CCD detectors has allowed a major progress in abundance derivations for globular cluster stars in the last years. Abundances deduced from high dispersion spectra now correlates well with other abundance indicators. I discuss some problems concerning the derivation of accurate metal abundances for globular clusters using high dispersion spectra from both the old photographic and the most recent CCD data. The discrepant low abundances found by Cohen (1980), from photographic material for M71 giants, are found to be due to the use of too high microturbulences.

Chromatin Structure And Dynamics

In the 30 years since the discovery of the nucleosome, our picture of it has come into sharp focus. The recent high-resolution structures have provided a wealth of insight into the function of the nucleosome, but they are inherently static. Our current knowledge of how nucleosomes can be reconfigured dynamically is at a much earlier stage. Here, recent advances in the understanding of chromatin structure and dynamics are highlighted. The ways in which different modes of nucleosome reconfiguration are likely to influence each other are discussed, and some of the factors likely to regulate the dynamic properties of nucleosomes are considered.
