“…The azimuthal angle ( χ ) dependence includes both Bragg and diffuse scattering from crystalline and noncrystalline components, respectively, in some unknown ratio. It would overestimate the unaligned part of MWNTs in the network if Hermans orientation function is calculated directly using the X‐ray diffraction diagram . After the background removal and peak area normalization, the tube number distribution around the orientation can be directly read out from the Bragg arc intensity of a narrow θ ‐range only containing the MWNT diffraction peak, and the Herman's orientation parameter were calculated:

S_{normald} = true(3 true〈 {normalcos}^{2} χ true〉 - 1 true) / 2

, where

true〈 {normalcos}^{2} χ_{}^{} true〉 = true({\overset{π}{\int_{0}}}_{}^{} I (χ) \sin χ \cos^{2} χ d χ true) / \int_{0}^{π} I (χ) \sin χ d χ

High-performance lightweight composites are sizably manufactured by impregnating continuous aligned carbon nanotube sheet (buckypapers) with self-reinforcing polyphenylene (Parmax) solution and followed by hot-press. The high processing pressure flattens nanotubes, which preferably p-stack with the aromatic rings of Parmax chain, and accordingly improve the load transfer. Both tensile strength and Young's modulus of the thermoplastic composites increase with the alignment degree of nanotubes, and can reach 950 MPa and 94 GPa, respectively, for the composite containing 50%stretched buckypaper. The highly aligned nanotubes also boost phonon transfer (70 W mK À1 ) and the electric conductivity (425 S cm -1 ) of the composite along the alignment direction. These combined outstanding properties would enable the thermoplastic composites in wide applications as multifunctional material.

In this study, an effective way is presented to synthesize a mussel‐inspired adhesive from two inexpensive commercially available materials: polyvinyl alcohol (PVA) and 3,4‐dihydroxybenzoic acid via the esterification reaction and deprotection technology. This bioinspired adhesive exhibits good bonding ability on metal, glass, plastic, and wood, and the maximum bonding strength can be up to 4.0 MPa at dry conditions on glass substrate. Meanwhile, this adhesive can also be used as a wet/underwater adhesive. Such a PVA‐based bioinspired adhesive may be used as a potential candidate for applications in industrial field.

“…The same aqueous solution became opaque at a higher temperature such as 35 8C (above the CP), which turned gradually into more transparent with light yellow after UV light irradiation. 37 The photocleavage process of NB-g-PHPA can be easily followed on UV-Vis absorption spectra, where o-nitrobenzyl and o-nitrosobenzaldehyde present two different bands. 38,39 UV-Vis absorbance spectra of NB-g-PHPA-3 aqueous solution were measured before and after different irradiation times (Supporting Information Fig.…”

The development of novel thermo‐ and photo‐dual‐responsive biodegradable polymeric micelles based on amphiphilic polyaspartamide derivatives (NB‐g‐PHPA‐g‐mPEG) for anticancer drug delivery is reported. The obtained polymers containing hydrophobic photocleavable o‐nitrobenzyl groups exhibit thermo‐ and photosensitivity. The micelles and paclitaxel‐loaded micelles based on the thermo‐ and photo‐dual‐sensitive polymers were prepared by a quick heating method without using toxic organic solvent. The paclitaxel release from the drug‐loaded micelles can be triggered under photoirradiation. Enhancement of the anticancer activity against HeLa cells was observed for paclitaxel‐loaded NB‐g‐PHPA‐g‐mPEG micelles after light irradiation, while the empty NB‐g‐PHPA‐g‐mPEG micelles with or without irradiation did not show any toxicity. Therefore, the thermo‐ and photo‐dual‐responsive NB‐g‐PHPA‐g‐mPEG micelles have a promising future applied as a light controlled drug delivery system for anticancer drugs. © 2016 Wiley Periodicals, Inc.
