Herein, dually heterogeneous hydrogels were constructed with two distinct strategies via dynamic bonds and supramolecular cross-links. The hydrogels showed discontinuous spatial ruptures, and the mechanical behaviors of hydrogels could be tuned. The primary heterogeneity resulted from a nonuniform distribution of dynamic and/or static cross-links. The presence of only primary heterogeneity within hydrogels led to uneven mechanical properties that were represented by discontinuous spatial ruptures during the stretching the hydrogel and therefore caused the necking deformation. Further introduction of the secondary heterogeneity by incorporating anisotropic cellulose nanocrystals (CNC) into the hydrogels allowed the adjustment of the necking phenomenon. Moreover, distinct CNC with diverse surface functionalities exhibited different effects: the “active” CNC with surface-attached dynamic bonds retarded the necking propagation, while the “neutral” CNC without further surface modification promoted the extension of necking points. Thus, the regulation of deformation and fracture mode of hydrogels was achieved by the synergy of dually heterogeneous structure."],["dc.identifier.doi","10.1021/acssuschemeng.7b04738"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65514"],["dc.language.iso","en"],["dc.title","Dually Heterogeneous Hydrogels via Dynamic and Supramolecular Cross-Links Tuning Discontinuous Spatial Ruptures"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

The adhesion performance of DAC adhesives was investigated using tensile shear strength measurements according to European standard EN302-1. Results showed the DO and the concentration of DACs had a predominant impact on the adhesion performance. The optimal formulation of DAC adhesives was found to be the aqueous solutions of DAC with a DO of 1.75 and a concentration of 40 wt %. The corresponding best bonding performance was represented by the bonding strength of about 9.53 MPa for beech wood specimens and 5.75 MPa for spruce wood specimens. Furthermore, wood specimens in shear strength tests mainly revealed a substrate failure mode rather than adhesive or cohesive failure. This indicates that the DAC adhesives possessed a stronger bonding strength than the wood itself.

The properties of irradiated films varying with ion fluence are investigated by means of Rutherford backscattering spectrometry, X-ray diffraction, transmission electron microscopy and spectroscopic ellipsometry. It was found that the Xe ions induce contraction and rhombohedral distortion of TiN lattice. The columnar structure was partially destroyed after irradiation, which introduce up to 1.5 at.% of Xe within the structure mostly concentrated around the projected ion range. The generation of defects due to the presence of heavy ions changes the optical constants of implanted films.

We investigated the magnetic anisotropy as a function of the residual film thickness and determined the thickness of the magnetically anisotropic layer as well as the magnitude of the magnetic anisotropy using by magneto-optical Kerr effect (MOKE) and Rutherford backscattering spectroscopy measurements. Ripple patterns were created by sputter erosion with 5 keV Xe ions under grazing incidence of 80 degrees with respect to the surface normal. For ion fluences of above 1x10(16) cm(-2), the formation of ripples, with wavelengths between 30 and 80 nm oriented parallel to the ion beam direction, is observed. MOKE measurements reveal a pronounced uniaxial magnetic anisotropy of the surface region of the films with orientation parallel to the ripple orientation and the ion beam direction. We find a layer thickness of 12 +/- 3 nm, in accordance with the average grain size. The magnetic anisotropy within this layer varies from about 25% for thick residual films toward 100% for films with less than 30 nm thickness. The magnitude of the magnetic anisotropy is determined by the shape anisotropy of the rippled surface as well as the interface roughness. We have demonstrated that sputter erosion yields highly anisotropic magnetic thin films and can be used to fabricate nanorods and nanowires with pronounced uniaxial magnetic anisotropy.

Surfactant sputtering is a novel ion beam erosion technique, which utilizes the steady state coverage of a substrate surface with foreign atoms simultaneously during sputter erosion by combined ion irradiation and atom deposition. These foreign atoms act as surfactants, which strongly modify the substrate sputtering yield on atomic to macroscopic length scales. The novel technique allows smoothing of surfaces, the generation of novel surface patterns and nanostructures, controlled shaping of surfaces on the nanometer scale and the formation of ultra-thin compound surface layers. We have sputter eroded ta-C films using 5 keV Xe ions under continuous deposition of either tungsten or titanium surfactants. This leads to the steady state formation of a W(x)C or a TiC/a-C nanocomposite surface layer of few nm thickness. Depending on the ion angle of incidence the layer is either smooth or nanostructured with a ripple- or dot-like surface topography. We have analyzed the surface topography, the composition and microstructure of the metal-carbon nanocomposites, and compare coverage dependent sputtering yields with SRIM and TRIDYN simulations.

However, most of them focused on characteristics, behaviors, properties, or functionalities of the NPs, while neglecting the interaction between NPs and solvents and thus the influence of solvents on the physical–chemical properties of NPs. In this paper, NPs based on cellulose 10-undecenoyl ester with total substitution of hydroxyl groups by undecenoyl moieties were prepared in various organic dispersants via nanoprecipitation. These NPs were further surface-modified with diverse functionalities via thiol–ene reactions on the terminal vinyl groups of undecenoyl moieties. The swelling behaviors of the resultant surface-modified NPs were systematically investigated via adding corresponding swelling solvents to the dispersions, fitting the swelling modes to different types of functions, and analyzing the factors influencing the swelling processes. It is concluded that different interactions including hydrogen bond interaction between swelling solvents and surface-modified outer layers as well as nonmodified interior parts of NPs are essential for different swelling trends. The swelling extents and tolerant capacities for swelling solvents in dispersant could be affected by the characters of dispersants, the surface functionalities of NPs, and the interaction between them.
