The surface treatment of polypropylene microfibers by plasma processing in oxygen and argon was studied with the motivation to increase their cohesion cement matrix. By treatment, it is possible modify mechanically, chemically or a combination both. were modified using reactive ion etching system. plasma. wettability measured Packed Cell method. Furthermore, weight before after modification mea...

Back Cover: In article 2200341, Bo-Lin Lin and co-workers discover a completely chemically recyclable polyester with high molecular weight, which originates from inexpensive CO2 1,3-butadiene. Furthermore, the material properties can be tailored via photo-initiated post-polymerization modification, causes light blue fluorescence.

Ionic residues influence the stability of collagen triple helices and play a relevant role in the spontaneous aggregation of fibrillar collagens. Collagen types I and II and some of their CNBr peptides were chemically modified in mild conditions with two different protocols. Primary amino groups of Lys and Hyl were N-methylated by formaldehyde in reducing conditions or N-acetylated by sulfosucc...

Colloidal chemically converted graphene sheets (CCGs) are able to contact with each other to form stable self-assembled stacked-CCGs via salt "invasion", which can serve as powerful building blocks for capturing double-stranded DNA.

Nanoporous carbon is coated by pure nickel via an electroless plating method. The nanoporous carbon provides a high-surface-area substrate, leading to a large capacitance; the nickel surface layer is of a high work function, resulting in a thermally sensitive electrode potential. Such a system is ideal for thermally chargeable supercapacitor (TCS) system, which converts low-grade heat (LGH) to ...

Nanoporous carbon based thermally chargeable supercapacitors (TCS) are characterized in a set of experiments for low-grade heat harvesting and storage. A TCS consists of two nanoporous electrodes immersed in an electrolyte solution. When the temperature of one of the electrodes rises, its electrode potential increases, and a significant amount of thermal energy is converted to electric energy. ...

objectives: stroke survivors develop their own strategies to combat disabilities, developing strategies to maintain or reestablish a sense of continuity after the disruptive life event that stroke represents, using strategies to foster hope during the process of adjusting to life after stroke and drawing on spiritual practices. the aim of this study is to identify the used and recommended strat...
