Preparation techniques of thin cyanoacrylate adhesive films for interface analysis
<p>For understanding the interactions between adhesives and different surfaces, the in-situ characterization of the interface is essential. Especially for highly reactive cyanoacrylates, better known as instant adhesives, the adhesion mechanism is poorly understood because, among other things, the characterization of the interface is difficult. The objective of this work is to evaluate the methods of thermal evaporating and spin coating to produce nm-thin, homogeneous films of cyanoacrylate. The aim is to enable spectroscopic analysis of the interface in the future.</p>
Effect of Environmental Weathering on Biodegradation of Biodegradable Plastic Mulch Films under Ambient Soil and Composting Conditions
<p>Plastic mulch films contribute to better crop production. Concerns for lack of sustainable disposal methods for conventional polyethylene (PE) mulch led to development of biodegradable plastic mulches (BDMs) that can be soil-incorporated or composted after use. Environmental weathering of BDMs during crop growth reduces their mechanical strength and alters the molecular structure of their polymeric components. However, the impact of weathering on BDMs' biodegradability is not fully understood. The biodegradability of agriculturally weathered and unweathered BDMs in soil and compost was compared using standardized laboratory tests (ASTM D5988 and D5338) using four BDMs (experimental polylactic acid and polyhydroxyalkanoate-based film [PLA/PHA] and three commercially available polybutyrate [PBAT]-based BDMs). In soil, biodegradation of weathered PLA/PHA was greater than its unweathered counterpart. For PBAT-based BDMs, the extent of biodegradation varied. A decrease of the weight-averaged molecular weight (M<sub>w</sub>) of PBAT and PLA and thermostability of PLA, PHA, PBAT, and starch components was observed during biodegradation in the soil. The proportion of the minor components PHA and starch decreased during biodegradation, indicating preferential utilization of PHA over PLA and starch over PBAT by microbes. Bacterial abundance was significantly higher than fungal abundance in soil and was more prominent in soil adjacent to weathered than unweathered BDM treatments. Under composting conditions, unweathered PBAT-enriched mulches yielded higher CO<sub>2</sub> evolution than their weathered counterpart. Together, these results suggest that environmental weathering enhances biodegradation of BDMs and mulch's polymeric constituents also influence the microbial degradation, more so for bacterial than fungal communities.</p>
High Oxygen Exchange Activity of Pristine La0.6Sr0.4FeO3–δ Films and Its Degradation - Dataset
<p>LSF thin film electrodes on YSZ substrates were characterized by electrochemical impedance spectrocopy inside the pulsed laser deposition chamber and in ex-situ emasurement setups. Inside the deposition chamber (in-situ) these electrodes revealed drastically lower polarization resistances. Exposure to several potential degradation sources inside the chamber showed this to be a rather robust effect. A detaield description is available in: https://doi.org/10.1149/1945-7111/abac2b</p> <p>This dataset includes the measured impedance spectra. The directory structure represents the order in which the se spectra appear in the publication. Several spectra are discussed in the context of several effects (e.g pO2 dependency and time dependency). In such cases, they are (redundantly) included in both relevant subdirectories.</p>

Disintegration of PBAT/PLA blown films modified with chain extending cross-linkers
<p>A biodegradable blend of PBAT – poly(butylene adipate-co-terephthalate) and PLA – poly(lactic acid) for blown film extrusion was modified with four multi-functional chain extending cross-linkers (CECL). The anisotropic morphology introduced during film blowing affects the degradation processes. As two CECL cause chain scission and the other two cross-linking, their compost (bio-)disintegration behavior was significantly altered with respect to the unmodified reference blend. The disintegration behavior at 30 and 60 °C was investigated by determining mass changes, Young’s moduli, tensile strengths, elongations at break and thermal properties. In order to quantify the disintegration behavior, the hole areas of blown films were evaluated after compost storage at 60 °C to calculate the kinetics of time dependent degrees of disintegration. The kinetic model of disintegration provides two parameters: initiation time and disintegration time. They quantify the effects of the CECL on the disintegration behavior of the PBAT/PLA compound. DSC revealed pronounced annealing effect after storage in compost at 30 °C, and the occurrence of the additional step-like increase of the heat flow at 75 °C after storage at 60 °C. The disintegration consists of processes which affect amorphous and crystalline phase of PBAT in different manner that cannot be understood by a hydrolytic chain degradation only.</p>

Data for: Assessment of cryogenic pretreatment for simulating environmental weathering in the formation of surrogate micro- and nanoplastics from agricultural mulch film
<p>Microplastics (MPs) and nanoplastics (NPs) from mulch films and other plastic materials employed in vegetable and small fruit production pose a major threat to agricultural ecosystems. For conducting controlled studies on MPs' and NPs' (MNPs') ecotoxicity to soil organisms and plants and fate and transport in soil, surrogate MNPs are<br>required that mimic MNPs that form in agricultural fields. We have developed a procedure to prepare MPs from plastic films or pellets using mechanical milling and sieving, and conversion of the resultant MPs into NPs through wet grinding, both steps of which mimic the degradation and fragmentation of plastics in nature. The major goal of this study was to determine if cryogenic exposure of two biodegradable mulch films effectively mimics the embrittlement caused by environmental weathering in terms of the dimensional, thermal, chemical, and biodegradability properties of the formed MNPs. We found differences in size, surface charge, thermal and chemical properties, and biodegradability in soil between MNPs' prepared from cryogenically treated vs. environmentally weathered films, related to the photochemical reactions occurring in the environment that were not mimicked by cryogenic treatment, such as depolymerization and cross-link formation. We also investigated the size reduction process for NPs and found that the size distribution was bimodal, with populations centered at 50 nm and 150–300 nm, and as the size reduction process progressed, the former subpopulation's proportion increased. The biodegradability of MPs in soil was greater than for NPs, a counter-intuitive trend since greater surface area exposure for NPs would increase biodegradability. The result is associated with differences in surface and chemical properties and to minor components that are readily leached out during the formation of NPs. In summary, the use of weathered plastics as feedstock would likely produce MNPs that are more realistic than cryogenically-treated unweathered films for use in experimental studies.</p>

Phases evolution and photocatalytic activity of Cu2O films electrodeposited from a non-pH-adjusted solution
<p>A pure-phase Cu<sub>2</sub>O film photocatalyst was successfully prepared by the electrodeposition technique from a non-pH-adjusted solution. To investigate the phase evolution and photocatalytic activity of the film, the electrodeposition was conducted at different deposition temperatures. Photocatalytic activity of the films was evaluated from methylene blue (MB) dye degradation. The Cu<sub>2</sub>O phase initially appeared at room temperature and its fraction was found to increase with increasing the deposition temperature, while the impurity phase was successfully diminished. A pure Cu<sub>2</sub>O film with a narrow optical bandgap energy of 1.96 eV was obtained at 75°C. The multi-faceted crystals were found to form at 45°C and became a truncated octahedral structure that possessed {111} and {100} facets as deposition temperature further increased. A preferred orientation growth of {110} facet, which is known to possess a relatively high surface energy, was produced at 75°C. The performance of MB photodegradation enhanced gradually by increasing the deposition temperature. The increase of photocatalytic activity could be attributed to the rise of photoelectrochemical response and the decrease of resistance charge transfer because of narrowing bandgap energy, increasing Cu<sub>2</sub>O fraction, and growing a relatively high catalytic activity facet which had escalated redox reaction that decomposed MB at the photocatalyst-solution interface.</p>
Data for: Magnetic-field-assisted molecular beam epitaxy: Engineering of Fe3O4 ultrathin films on MgO(111)
<p>Molecular beam epitaxy is widely used for engineering low-dimensional materials. Here, we present a novel extension of the capabilities of this method by assisting epitaxial growth with the presence of an external magnetic field (MF). MF-assisted epitaxial growth was implemented under ultra-high vacuum conditions thanks to specialized sample holders for generating in-plane or out-of-plane MF and dedicated manipulator stations with heating and cooling options. The significant impact of MF on the magnetic properties was shown for ultra-thin epitaxial magnetite films grown on MgO(111). Using in situ and ex situ characterization methods, scanning tunneling microscopy, conversion electron Mössbauer spectroscopy, and the magneto-optic Kerr effect, we showed that the in-plane MF applied during the reactive deposition of 10 nm Fe3O4(111)/MgO(111) heterostructures influenced the growth morphology of the magnetite films, which affects both in-plane and out-of-plane characteristics of the magnetization process. The observed changes are explained in terms of modification of the effective magnetic anisotropy.</p>
