Fabrication of partially biobased carbon fibers from novel lignosulfonate-acrylonitrile copolymers

open access: yes, 2017
Lignin, as an abundant carbon-rich renewable resource, is a promising precursor for carbon fibers. However, due to the poor spinnability of lignin, a great challenge comes from the spinning of precursor fibers.

Thermally Modulated Metasurface Sensor for Dynamic and Time‐Resolved Isolation of Extracellular Vesicles

open access: yesAdvanced Materials, EarlyView.
A thermally adaptive plasmonic metasurface, functionalized with poly(N‐isopropylacrylamide) (PNIPAM) and anti‐CD63 antibodies, enables precise, on‐demand capture and release of extracellular vesicles (EVs). Delivering high recovery, improved purity, and intact vesicle structure, the platform offers a versatile, label‐free solution for real‐time EV ...

STUDY OF THE CONDUCTIVITY OF VARIOUS SIZE FORMS CARBON PARTICLES USED AS FILLERS OF EPOXY POLYMER COMPOSITES

open access: yes, 2018
The electrical conductivity of a polymer can be increased by the addition of a conductive material in particulate or fibrillar form. That are a lot of possibilities of conducting additives composites, for example chopped or milled carbon fibers, over ...

Clustomesogen Showing Sub‐Zero Liquid Crystal Properties: Supramolecular Assembly Between Cs2[Mo6Ii8(OCOC2F5)6] and Hexaethylenoxide Containing Mesogenic Dimers

open access: yesAdvanced Materials, EarlyView.
Associating a red‐NIR phosphorescent octahedral hexanuclear molybdenum cluster compound with hexaethyleneoxide chains bearing mesogenic units on both ends leads to an emissive hybrid liquid crystal showing mesomorphism on a very unusual temperature range down to −25°C.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

open access: yesAdvanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.

Fabrication of Electrospun Carbon Nanocomposite Fibers from PAN and PAA Blended Solutions

open access: yes, 2007
Carbon fibers have been prepared from a wide variety of precursors ranging from natural materials to synthetic polymer fibers, the primary requirement being for a material that not melt on pyrolysis in an inert atmosphere. Among them, poly-acrylonitrile (
