Authors: Hollands Jutta , Tudiwer David , Korjenic Azra , Bretschneider Betül Betül 
Published: June 2018

AbstractDiese Arbeit zeigt, wie sich unterschiedliche Gebäude und deren unmittelbare Umgebung auf das Mikroklima in der Stadt auswirken und das Innenraumklima beeinflussen. Dafür wurden im Rahmen eines Forschungsprojektes Oberflächentemperaturen an Gebäuden, die Lufttemperaturen sowie die Luftfeuchtigkeit in Innenräumen, im Außenraum vor Fassaden und im Straßenraum gemessen. Der Niederschlag, die Sonneneinstrahlung und die Windgeschwindigkeit wurden ebenso über einen langen Zeitraum im Versuchsgebiet untersucht. Aus den Messdaten werden Auswirkungen der unterschiedlichen Gebäude auf das Innen‐ und Außenraumklima an Hitzetagen abgeleitet. Der Sockelbereich und die Fassaden der Gebäude wurden in Abhängigkeit von Farbe, Aufbau, Struktur und Dämmung analysiert. Die messtechnischen Ergebnisse dieser Arbeit bieten die Basis zur Entwicklung von Maßnahmen zur Umgestaltung und Begrünung des Straßenraumes samt angrenzenden Gebäudefassaden am Beispiel des vom UHI (Urban Heat Island)‐Effekt betroffenen Pilotgebietes Aspangstraße.
It is for you, or it is for me: How relationship dependence affects gift image consistency in romantic relationships
Authors: Cong Rifei , Luo Biao , Li Tieshan , Wang Chengyuan 
Published: June 2018

AbstractRecently, consumer behavior research has been focusing on decision‐making in relationships. This research considers an important context, romantic gift giving, in which givers choose gifts that are perceptually consistent with both their own self‐image and the recipients' self‐image. Based on interdependence theory, we investigate how the relationship dependence between romantic couples can affect gift image consistency. According to the results, the giver's level of dependence plays a positive role in the consistency between the recipient's self‐image and the gift image (gift‐recipient consistency) and plays a negative role in the consistency between the giver's self‐image and the gift image (gift‐giver consistency). The mutuality of dependence could strengthen or weaken the effect of the giver's level of dependence on gift image consistency, and this effect is carried through the giver's relationship power.
Capturing and Stabilizing Folded Proteins in Lattices Formed with Branched Oligonucleotide Hybrids
Authors: Schwenger Alexander , Jurkowski Tomasz P. , Richert Clemens 
Published: June 2018

AbstractThe encapsulation of folded proteins in stabilizing matrices is one of the challenges of soft‐matter materials science. Capturing such fragile bio‐macromolecules from aqueous solution, and embedding them in a lattice that stabilizes them against denaturation and decomposition is difficult. Here, we report that tetrahedral oligonucleotide hybrids as branching elements, and connecting DNA duplexes with sticky ends can assemble into materials. The material‐forming property was used to capture DNA‐binding proteins selectively from aqueous protein mixtures. The three‐dimensional networks also encapsulate guest molecules in a size‐selective manner, accommodating proteins up to a molecular weight of approximately 159 kDa for the connecting duplex lengths tested. Exploratory experiments with green fluorescent protein showed that, when embedded in the DNA‐based matrix, the protein is more stable toward denaturation than in the free form, and retains its luminescent properties for at least 90 days in dry form. The noncrystalline biohybrid matrices presented herein may be used for capturing other proteins or for producing functional materials.
Trimethyl Lock: A Multifunctional Molecular Tool for Drug Delivery, Cellular Imaging, and Stimuli‐Responsive Materials
Authors: Okoh Okoh Adeyi , Klahn Philipp 
Published: June 2018

AbstractTrimethyl lock (TML) systems are based on ortho‐hydroxydihydrocinnamic acid derivatives displaying increased lactonization reactivity owing to unfavorable steric interactions of three pendant methyl groups, and this leads to the formation of hydrocoumarins. Protection of the phenolic hydroxy function or masking of the reactivity as benzoquinone derivatives prevents lactonization and provides a trigger for controlled release of molecules attached to the carboxylic acid function through amides, esters, or thioesters. Their easy synthesis and possible chemical adaption to several different triggers make TML a highly versatile module for the development of drug‐delivery systems, prodrug approaches, cell‐imaging tools, molecular tools for supramolecular chemistry, as well as smart stimuliresponsive materials.
Exfoliated Nanosheets of a CuII Coordination Polymer Modulate Enzyme Activity of α‐Chymotrypsin
Authors: Sarkar Koushik , Dastidar Parthasarathi 
Published: June 2018

AbstractA 2D coordination polymer derived from 5‐azidoisophthalic acid (AIA) and Cu(NO3)2 was designed with the aim of modulating the activity of a digestive enzyme α‐chymotrypsin (ChT). The coordination polymer namely {[Cu0.5(μ‐AIA)0.5(H2O)]⋅2 H2O}α (CP1) was successfully synthesized and fully characterized by single‐crystal X‐ray diffraction (SXRD). An exfoliated nanosheet (ENS) of CP1 was readily produced by overnight stirring of hand‐ground CP1 crystals dispersed in DMSO. ENS(CP1) was demonstrated to be acting as an inhibitor of ChT; as much as ≈97 % inhibition of ChT was achieved with 100 μm of ENS(CP1) using N‐succinyl‐l‐phenylalanine‐p‐nitroanilide (SPNA) as substrate. Enzyme kinetics data revealed that the inhibition of ChT followed a competitive pathway. An enzyme assay under varying ionic strength and varying concentration of free histidine revealed that the active site His‐57 participated in coordination with the CuII metal center of ENS(CP1) thereby preventing the substrate (SPNA) from binding with the enzyme resulting in efficient inhibition.
Porous Metal‐Organic Polyhedral Framework containing Cuboctahedron Cages as SBUs with High Affinity for H2 and CO2 Sorption: A Heterogeneous Catalyst for Chemical Fixation of CO2
Authors: Maity Kartik , Karan Chandan Kumar , Biradha Kumar 
Published: June 2018

AbstractDevelopment of active porous materials that can efficiently adsorb H2 and CO2 is needed, due to their practical utilities. Here we present the design and synthesis of an interpenetrated CuII metal‐organic framework (MOF) that is thermally stable, highly porous and can act as a heterogeneous catalyst. The CuII‐MOF contains a highly symmetric polyhedral metal cluster (Cu24) with cuboctahedron geometry as secondary building unit (SBU). The double interpenetration of such huge cluster‐containing nets provides a high density of open metal sites, due to which it exhibits remarkable H2 storage capacity (313 cm3g−1 at 1 bar and 77 K) as well as high CO2 capture ability (159 cm3g−1 at 1 bar and 273 K). Further, its propensity towards CO2 sorption can be utilized for the heterogeneous catalysis of the chemical conversion of CO2 into the corresponding cyclic carbonates upon reaction with epoxides, with high turnover number and turnover frequency values.

AbstractPTPRJ is a receptor‐like protein tyrosine phosphatase mainly known for its antiproliferative and tumor‐suppressive functions. PTPRJ dephosphorylates several growth factors and their receptors, negatively regulating cell proliferation and migration. We recently identified a disulfide‐bridged nonapeptide, named PTPRJ‐19 (H‐[Cys‐His‐His‐Asn‐Leu‐Thr‐His‐Ala‐Cys]‐OH), which activates PTPRJ, thereby causing cell growth inhibition and apoptosis of both cancer and endothelial cells. With the aim of replacing the disulfide bridge by a chemically more stable moiety, we have synthesized and tested a series of lactam analogues of PTPRJ‐19. This replacement led to analogues with higher activity and greater stability than the parent peptide.
Divergent projection patterns of M1 ipRGC subtypes
Authors: Li Jennifer Y. , Schmidt Tiffany M. 
Published: June 2018

AbstractIn addition to its well‐known role in pattern vision, light influences a wide range of non‐image forming, subconscious visual behaviors including circadian photoentrainment, sleep, mood, learning, and the pupillary light reflex. Each of these behaviors is thought to require input from the M1 subtype of melanopsin‐expressing, intrinsically photosensitive retinal ganglion cell (ipRGC). Recent work has demonstrated that the M1 subtype of ipRGC can be further subdivided based on expression of the transcription factor Brn3b. Brn3b‐positive M1 ipRGCs project to the olivary pretectal nucleus and are necessary for the pupillary light reflex, while Brn3b‐negative M1 ipRGCs project to the suprachiasmatic nucleus (SCN) and are sufficient for circadian photoentrainment. However, beyond the circadian and pupil systems, little is known about the projection patterns of M1 ipRGC subtypes. Here we show that Brn3b‐positive M1 ipRGCs comprise the majority of sparse M1 ipRGC inputs to the thalamus, midbrain, and hypothalamus. Our data demonstrate that very few brain targets receive convergent input from both M1 ipRGC subpopulations, suggesting that each subpopulation drives a specific subset of light‐driven behaviors.
Properties Modification of Nanosized Hollow Zeolite Crystals by Desilication

Published: June 2018

AbstractA strategy to modify the properties of hollow zeolite was developed by leaching the “parent” zeolite in alkaline solution. A systematic study was performed to identify the effect of both the synthesis conditions of “parent” zeolite and the leaching conditions on the properties of hollow zeolite. Fine‐tuning the leaching conditions, i. e. the concentration of sodium hydroxide solution, allows control over the degree of hollowness of the zeolite, achieving the introduction of larger voids in different locations of individual crystals, which is a key factor if the crystals are to be used for catalytic applications. In addition, a hypothesis was proposed to explain the formation of hollow ZSM‐5 crystals. By replacing part of tetrapropylammonium hydroxide (TPAOH) with tetrapropylammonium bromide (TPABr) as the structure‐directing agent (SDA), the “parent” zeolites obtained were less stable in alkaline solution and formed hollow structures more easily. The size of hollow zeolite crystals could be easily controlled by adjusting the water content of the synthesis gel. Finally, crystals with double shells were prepared by a method involving two consecutive crystallizations followed by base leaching. Overall, fine‐tuning of zeolite synthesis and post‐synthesis conditions leads to control of the structure of hollow zeolite crystals.

Published: June 2018

AbstractElectron beam irradiated fluorinated materials, which are used for an optical solar reflector of spacecraft, have been investigated using a space charge measurement system under dc high stress. It was found that a large amount of space charge accumulated in the electron beam irradiated ethylene‐tetrafluoroethylene and fluorinated ethylene‐propylene copolymer under dc high stress, while it was not observed in nonirradiated them. In this report, a dependence of relaxation time after the irradiation on the space charge accumulation characteristics was also studied.
Handle with Care: Establishing Catch Limits for Fish Stocks Experiencing Episodic Natural Mortality Events

Published: June 2018

Abstract
Harmful blooms of the dinoflagellate Karenia brevis, known as “red tides,” are responsible for major episodic fish kills in the Gulf of Mexico. In response to management concerns, we conducted a management strategy evaluation to examine whether decision-making reactivity to event occurrence or precautionary catch limit reductions could aid in achieving fishery objectives. Simulated stock dynamics were representative of Gulf of Mexico Red Grouper Epinephelus morio, and assessment of simulated data involved estimation of time-varying natural mortality. We found that both unresponsive yet precautionary catch limits and reactive decision making could improve achievement of fishery objectives, although practical impediments to reactive strategies abound. Where catch limit reductions were introduced to buffer against scientific uncertainty, a trade-off was evident that required recognizing constraints in stock assessment reliability (given the complexities of estimating time-varying natural mortality) and balancing these constraints against desirability for high catch rates. Our study provides a narrative on the ways in which management guidance can be structured to address uncertainty about future occurrences of episodic natural mortality events.

AbstractThe tolerable dietary intake of cadmium was recommended at provisional tolerable monthly intake of 25 μg kg−1 body weight. However, several studies indicated that this tolerable level should be re‐evaluated for sufficient health protection. In this study, we show the reference levels of dietary cadmium intake for renal dysfunction by using a benchmark dose (BMD) approach. A total of 790 subjects (302 men and 488 women) living in control and cadmium‐polluted areas were included. The dietary cadmium intake was estimated by a food survey. Blood cadmium, urinary cadmium and renal function markers (microalbuminuria, N‐acetyl‐β‐d‐glucosaminidase [NAG] and its isoform B [NAGB], β2‐microglobulin and retinol binding protein) in urine were measured. We calculated the 95% lower confidence bounds of BMD (BMDLs) of cumulative cadmium intake. In control and two polluted areas, the median cumulative cadmium intake was 0.5, 2.1 and 11.1 g. The odds ratio of the intermediate (1.0–3.0 g), second highest (3.0–11.0 g) and the highest cumulative cadmium intake (>11.0 g) compared with the lowest cumulative cadmium intake (<1.0 g) were 2.8 (95% CI: 1.4–5.8), 8.1 (95% CI: 3.8–17.2) and 11.4 (95% CI: 6.5–26.4) for urinary NAG and 6.6 (95% CI: 3.2–13.8), 14.8 (95% CI: 6.8–32.2) and 22.5 (95% CI: 10.7–47.5) for urinary NAGB. The BMDLs of cumulative cadmium intake were 1.1–1.2 g (benchmark response [BMR] = 5%) for urinary NAG, and were 0.7–0.9 g (BMR = 5%) for urinary NAGB, and were 1.3–1.4 g (BMR = 5%) for urinary β2‐microglobulin. The BMDLs of cumulative cadmium intake in a Chinese population were lower than the critical standard previously reported. Further evaluations are needed for sufficient health protection.

AbstractBACKGROUNDEach region of the world has its own methods, protocols, instruments and procedures regarding how to brew coffee. The final result in the cup is strongly affected by the extraction method, and many studies have focused on this subject. However, few studies have investigated slow, cold extraction methods, despite their popularity among baristas. Therefore, the present study aimed to characterize and compare two cold extraction methods: cold brew and cold drip.RESULTSPhysical and chemical analyses were used to describe coffee beverages in terms of pH, total solids, refractive index, density and viscosity. Caffeine and cinnamic acids were quantified using high‐performance liquid chromatography (HPLC)/diode array detector and HPLC/mass spectrometry. A sensory evaluation included aroma, flavor and textural attributes.CONCLUSIONSSignificant differences were found in the chemical and physical parameters, both between and within the two methods, as a function of the extraction temperature and contact time. Similarly, the sensory evaluation found differences in flavor profiles, as measured in terms of bitterness, sweetness, sourness and global intensity. © 2018 Society of Chemical Industry
Build‐Up of Dissipative Optical Soliton Molecules via Diverse Soliton Interactions
Authors: Peng Junsong , Zeng Heping 
Published: June 2018

AbstractSolitons can form bound states that are frequently referred to as soliton molecules as they exhibit molecule‐like dynamics. The build‐up phase of the optical soliton molecule remains elusive. Here, by means of a time‐stretch technique that enables real‐time access to the spectral and temporal dynamics, rich nonlinear processes involved in the build‐up of soliton molecules are revealed in an ultrafast fibre laser. Specifically, the formation of closely‐ and well‐separated bound solitons are resolved. In both cases, the build‐up phases consist of three nonlinear stages including mode locking, soliton splitting, and soliton interactions. For closely‐separated bound solitons, soliton interactions display wide diversities in repeated measurements, including soliton attraction, repelling, collision, vibration, and annihilation. For well‐separated bound solitons, repulsive interactions dominate the soliton interactions. Numerical simulations corroborate these experimental observations. Furthermore, a conceptually different soliton molecule, the intermittent‐vibration soliton molecule, is discovered and characterized. It is the intermediate state between the vibrational and stationary soliton molecules. The author's findings could assist in the understanding of the build‐up phase of localized structures in different dissipative systems.
Single‐Shot Optical Anisotropy Imaging with Quantitative Polarization Interference Microscopy

Published: June 2018

AbstractOptical anisotropy measurement is essential for material characterization and biological imaging. In order to achieve single‐shot mapping of the birefringence parameters of anisotropic samples, a novel polarized light imaging concept is proposed, namely quantitative polarization interference microscopy (QPIM). QPIM can be realized through designing a compact polarization‐resolved interference microscopy system that captures interferograms bearing sample's linear birefringence information. To extract the retardance and the orientation angle maps from a single‐shot measurement, a mathematical model for QPIM is further developed. The QPIM system is validated by measuring a calibrated quarter‐wave plate, whose fast‐axis orientation angle and retardance are determined with great accuracies. The single‐shot nature of QPIM further allows to measure the transient dynamics of birefringence changes in material containing anisotropic structures. This application is demonstrated by capturing transient retardance changes in a custom‐designed parallel‐aligned nematic liquid crystal‐based device.

Shape memory property and underlying mechanism by the phase separation control of poly(ϵ‐caprolactone)/poly(ether‐b‐amide)
Authors: Liu Xinran , Huang Miaoming , Zhu Ping , Dong Siyuan , Dong Xia , Wang Dujin 
Published: June 2018

AbstractIn this work, a poly(ϵ‐caprolactone)/poly(ether‐b‐amide) blend with weight ratio 35/65 was prepared by solution mixing and compression molding. A simple and sensible method to control the phase separation structure was introduced by adjusting the temperature and time for the process of phase separation. Samples with obviously different morphology were obtained and the microstructure was studied by phase contrast optical microscopy, SEM and DSC. The shape memory properties were measured using dynamic mechanical analysis. The results show that the shape memory performance of the blend is closely related to the phase morphology, and the blend with co‐continuous structure has a better shape memory property. A model is put forward to illustrate schematically the microstructural evolution during the shape memory process. © 2018 Society of Chemical Industry

AbstractThe presence of iodide ions during the growth of gold nanorods strongly affects the shape of the final products, which is proposed to be due to selective iodide adsorption on certain crystallographic facets. Therefore, a detailed structural and morphological characterization of the starting rods is crucial toward understanding this effect. Electron tomography is used to determine the crystallographic indices of the lateral facets of gold nanorods, as well as those present at the tips. Based on this information, density functional theory calculations are used to determine the surface and interface energies of the observed facets and provide insight into the relationship between the amount of iodide ions in the growth solution and the final morphology of anisotropic gold nanoparticles.
Wartungsfreier Korrosionsschutz für Stahl‐Verbundbrücken mit Walzprofilen
Authors: Rademacher Dennis 
Published: June 2018

AbstractZunehmende Schäden an Brücken in Deutschland, verbunden mit teilweise massiven langfristigen Auswirkungen auf den Straßenverkehr, haben gezeigt, wie wichtig es ist, die Dauerhaftigkeit der Infrastruktur und damit die Mobilität der Menschen sowie den Austausch von Gütern sicherzustellen. Insbesondere Korrosionsschäden können in Zukunft durch die Verwendung von alternativen Schutzsystemen für Stahl‐ und Verbundbrücken nachhaltig verhindert werden. Sowohl die Feuerverzinkung mit einer Schichtdicke von mindestens 200 µm als auch Wetterfeste Baustähle bieten gegenüber den traditionell angewendeten Beschichtungssystemen über den Lebenszyklus des Bauwerks entscheidende Vorteile: Sie erfordern keine Instandsetzungen und somit keinen Eingriff in den laufenden Verkehr. Bei Verwendung dieser Systeme in Verbindung mit Walzprofilen ergeben sich weitere signifikante Vorteile, die Verbundbrücken wirtschaftlich interessanter und dauerhafter machen.

AbstractUm die Funktionalität von Verkehrswegen dauerhaft zu gewährleisten, bedarf es fortwährender Erhaltung, Anpassung und Weiterentwicklung. Bei den Bundesfernstraßen hat für diese Prozesse eine Phase mit besonderer Dynamik begonnen. Hierfür gibt es mehrere Ursachen, die letztlich zum Finanzhochlauf für die Infrastruktur der Bundesfernstraßen geführt haben. Insbesondere für den Brückenbau ergeben sich dadurch neue Herausforderungen und Chancen. Wenngleich einige Punkte Bauweisen übergreifend Gültigkeit besitzen, erfolgt die Betrachtung aus der Perspektive des Stahl‐ und Verbundbrückenbaus.
