Brown cotton fiber is the major raw material for colored cotton industry. Previous studies have showed that the brown pigments in cotton fiber belong to proanthocyanidins (PAs). To clarify the details of PA biosynthesis pathway in brown cotton fiber, gene expression profiles in developing brown and white fibers were compared via digital gene expression profiling and qRT-PCR. Compared to white c...

Three-dimensional graphene-based structures such as graphene aerogels or foams have shown applications in energy, environmental matters, and many other areas. Here, we present a method to convert raw cotton into functional aerogels containing a significant amount of nitrogen-doped graphene (N-graphene) sheets grafted on carbonized cellulose fibers. Urea was introduced into raw cotton as a molec...

Diffusion MRI [1] and fiber tractography have become a reference to study the neural structure of the brain white matter. Standard tractography algorithms behave generally locally, i.e., a single fiber is initiated at a seed point and is constructed iteratively, thus making fibers subject to cumulative errors. On the contrary, in global approaches the entire white matter is tracked at once: in ...

From application perspectives in adsorption, activated carbon fiber (ACF) is by far one of the most important carbon nanoporous materials to be considered. It has great advantages over other commercial porous storage materials. Activated carbon fiber (ACF) is a promising microporous material with a fiber shape and well-defined porous structure. In general, production of ACF can be commercially ...

INTRODUCTION Arundo donax, Poaceae, commonly known as “nalgrass,” is a member of the reed family that grows both wild and cultivated in California. Evaluated as a potential paper fiber source in Italy and Hungary over 50 years ago and included in the 1970s USDA evaluation of potential annual fiber crops, the high potential of A. donax has not been widely recognized. A new evaluation was begun i...

From the nutritional point of view, data on dietary fiber content, tannin and in vitro protein digestibility of processed millet is of importance, because millets are never eaten raw. Effects of commonly used traditional methods on dietary fiber, tannin content and %IVPD of two locally available pearl millet varieties (Kalukombu and Maharashtra Rabi Bajra) were investigated. The millet was subj...

Due to the problems of potential corrosion and thermal expansion differences between traditional metal connecting pieces and carbon fiber poles, it is difficult for them to meet the operating requirements of truss structures in the environment of stratosphere. Based on the large scale composite space truss structure of stratosphere aerostats, the carbon fiber flange connection joints were studi...

Cellulose constitutes an important raw material for many industries. However, the superb load-bearing properties of cellulose are accompanied by poor chemical reactivity. The hydroxyl groups on cellulose surfaces can be reacted but usually not without loss of fiber integrity and strength. Here, we describe a novel chemoenzymatic approach for the efficient incorporation of chemical functionality...

The dates of receipt and acceptance should be inserted later This paper describes the general characteristics of raw data from fiber-fed spectrographs in general and fiber-fed IFUs in particular. The different steps of the data reduction are presented, and the techniques used to address the unusual characteristics of these data are described in detail. These techniques have been implemented in ...

Understanding the complicated failure mechanisms of hierarchical composites such as fiber yarns is essential for advanced materials design. In this study, we developed a new Monte Carlo model for predicting the mechanical properties of fiber yarns that includes statistical variation in fiber strength. Furthermore, a statistical shear load transfer law based on the shear lag analysis was derived...
