Inorganic-Organic Hybrid Nanocomposite for Biomedical Applications

Recently, inorganic-organic hybrid nanocomposites (IOHNs) have drawn special attention for their extraordinary properties and wide spread applications in diverse fields such as cell imaging, drug delivery, photothermal therapy, bio-sensing, catalysis, energy storage and conversion, gas sensing, etc. [13]. In hybrid nanocomposite, the term ‘hybrid’ refers to the combination of inorganic and organic components that form a single material called nanocomposite with improved/unique properties than the individual components [4]. Origin of the properties of an IOHN can found dependent upon its particle morphology in addition to the extent of interfacial/chemical interactions existed between the components [5]. An IOHN can be more advantageous than the ordinary mixture of components for several advanced applications [1-3] but some important physicochemical characteristics of IOHNS like size, composition, surface-to-volume ratio, aggregation, stability, solubility in body fluid etc. need to study before considering the materials for biomedical applications [6].
The Origin of Heavy Metals and Radionuclides Accumulated in the Soil and Biota Samples Collected in Svalbard, Near Longyearbyen

Abstract Heavy metals and radioactive compounds are potentially hazardous substances for plants, animals and humans in the Arctic. A good knowledge of the spatial variation of these substances in soil and primary producers, and their sources, is therefore essential. In the samples of lichen Thamnolia vermicularis, Salix polaris and Cassiope tetragona, and the soil samples collected in 2014 in Svalbard near Longyearbyen, the concentrations of the following heavy metals were determined: Mn, Ni, Cu, Zn, Cd, Pb and Hg, as well as the activity concentrations of the following: K-40, Cs-137, Pb-210, Pb-212, Bi-212, Bi-214, Pb-214, Ac-228, Th-231 and U-235 in the soil samples. The differences in the concentrations of the analytes accumulated in the different plant species and soil were studied using statistical methods. Sea aerosol was indicated as the source of Pb, Hg, Cs-137, Pb-210 and Th-231 in the studied area. A relatively high concentration of nickel was determined in the biota samples collected near Longyearbyen, compared to other areas of Svalbard. It was supposed that nickel may be released into the atmosphere as a consequence of the local coal mining around Longyearbyen.
Fabrication of core–shell Ag@pDA@HAp nanoparticles with the ability for controlled release of Ag+ and superior hemocompatibility

Silver nanoparticles (Ag-NPs) are a type of crucial bactericide due to their excellent antibacterial properties. However, the application of Ag-NPs in clinics and in bone tissue engineering is hampered because of their unabiding antibacterial efficacy and undesirable biological properties such as cytotoxicity and inferior hemocompatibility. In this study, Ag-NPs were modified with polydopamine (pDA) and hydroxyapatite (HAp) to prepare novel and multifunctional core (Ag-NPs)–shell (pDA)–shell (HAp) nanoparticles (Ag@pDA@HAp-NPs). The Ag+ release rate was reduced by about 80% on the first day, and then Ag+ was slowly released, which implied that the core–shell Ag@pDA@HAp-NPs could effectively control the release of Ag+. The core–shell Ag@pDA@HAp-NPs could obviously inhibit the growth of E. coli and S. aureus, and the bactericide rate of the Ag@pDA@HAp-NPs was up to 99.99% after being cultured for 24 h. Furthermore, the synthesized Ag@pDA@HAp-NPs exhibited superior hemocompatibility due to the favorable blood compatibility of the pDA coating and HAp shell as well as the controlled release of Ag+. Thus, the core–shell Ag@pDA@HAp-NPs, with the ability for the controlled release of Ag+ and superior hemocompatibility, are promising for reducing cytotoxicity and achieving long-term antibacterial properties, and could have potential applications in clinics and in bone tissue engineering.
N-Type Semiconducting Behavior of Copper Octafluorophthalocyanine in an Organic Field-Effect Transistor

Based on the crystal structure analysis, the overlap integral between the frontier molecular orbitals of adjacent F8CuPcs in the one-dimensional chain is estimated: the overlap integral between the lowest unoccupied molecular orbitals is 5.4 × 10−3, which is larger than that in a typical n-type semiconducing material F16CuPc (2.1 × 10−3), whereas that between the highest occupied molecular orbitals is 2.9 × 10−4. Contrary to previous studies in air, we found that an organic field-effect transistor (OFET) composed of F8CuPc essentially shows clear n-type semiconducting behavior in vacuum.

ER quality control in male fertility

Protein disulphide isomerase is a member of the thioredoxin superfamily, resides in the endoplasmic reticulum (ER) and catalyses the formation of disulphide bonds within or between polypeptides, enabling protein quality control. PDILT is a member of the PDI family that specifically resides in the testes and is expressed under developmental control. Recent work has found that, unlike PDI (which possesses the classical CXXC sequence), PDILT has an SXXC domain. This suggests that PDILT does not function fully as a disulphide oxidoreductase but may work as a chaperone. We wished to investigate PDILT and compare it with other PDI proteins, to study the evolution of the PDILT gene and to decipher its protein-protein interactions. Using sequence analysis of PDILT using the BLAST program, the PDILT protein was compared with other PDI proteins in homosapiens and in other species. We then probed further to investigate the expression and interaction of PDILT with other proteins. A transfected cell line model to investigate wt and mutant PDILT was established, and mouse testis tissue lysate was also used to study PDILT interactions. Using immunofluorescence, western blot analysis, and immunoprecipitation techniques, it was established that PDILT forms intermolecular-disulphide complexes and interacts with other chaperones such as CALR3 and CLGN. Sequence analysis demonstrated conserved amino acids in the b and b’ domains that reflect the specialised roles of the a-a’-b-b’ domains of PDILT. The cysteine residues responsible for inter-molecular disulphide bond formation were identified and found to be important in the interaction of PDILT with CLGN. Lastly, a novel function of the unique tail domain of PDILT was found. The work in this thesis suggests that the tail may be important for the integrity and half-life of the PDILT protein. These studies will help to elucidate the role of PDILT in governing male fertility.

From Electrospun Polymer Core–Shell Fibers to Polymer Hemispheres and Spheres: Two Types of Transformation Processes and Tearing Films with Linearly Arranged Cavities

Electrospun polymer core–shell fibers have gained much attention because of their promising applications in areas such as electronic devices, drug delivery, and tissue engineering. The morphology transformation of polymer core–shell fibers, however, has been rarely investigated. Here, we study the effect of thermal annealing on the morphology transformation of electrospun polystyrene (PS)/poly(methyl methacrylate) (PMMA) core–shell fibers on PMMA films. Two types of transformation processes are discovered. In the first type of the transformation process (type I), the PS cores transform to hemispherical particles after the annealing process; in the second type of the transformation process (type II), the PS cores transform to spherical particles after the annealing process. The measured sizes of the hemispherical and spherical PS domains fall into two classified regions, as predicted for the two different types of transformation processes. It is also observed that the growth rates of the undulated amplitud.

Retrieval of Ocean Surface Currents and Winds Using Satellite SAR backscatter and Doppler frequency shift

Ocean surface winds and currents play an important role for weather, climate, marine life, ship navigation, oil spill drift and search and rescue. In-situ observations of the ocean are sparse and costly. Satellites provide a useful complement to these observations. Synthetic aperture radar (SAR) is particularly attractive due to its high spatial resolution and its capability to extract both sea surface winds and currents day and night and almost independent of weather. The work in this thesis involves processing of along-track interferometric SAR (ATI-SAR) data, analysis of the backscatter and Doppler frequency shift, and development of wind and current retrieval algorithms. Analysis of the Doppler frequency shift showed a systematic bias. A calibration method was proposed and implemented to correct for this bias. Doppler analysis also showed that the wave contribution to the SAR Doppler centroid often dominates over the current contribution. This wave contribution is estimated using existing theoretical and empirical Doppler models. For wind and current retrieval, two methods were developed and implemented. The first method, called the direct method, consists of retrieval of the wind speed from SAR backscatter using an empirical backscatter model. In order to retrieve the radial current, the retrieved wind speed is used to correct for the wave contribution. The current retrieval was assessed using two different (theoretical and empirical) Doppler models and wind inputs (model and SAR-derived). It was found that the results obtained by combining the Doppler empirical model with the SAR-derived wind speed were more consistent with ocean models. The second method, called Bayesian method, consists of blending the SAR observables (backscatter and Doppler shift) with an atmospheric and an oceanic model to retrieve the total wind and current vector fields. It was shown that this method yields more accurate estimates, i.e. reduces the models biases against in-situ measurements. Moreover, the method introduces small scale features, e.g. fronts and meandering, which are weakly resolved by the models. The correlation between the surface wind vectors and the SAR Doppler shift was demonstrated empirically using the Doppler shift estimated from over 300 TanDEM-X interferograms and ECMWF reanalysis wind vectors. Analysis of polarimetric data showed that theoretical models such as Bragg and composite surface models over-estimate the backscatter polarization ratio and Doppler shift polarization difference. A combination of a theoretical Doppler model and an empirical modulation transfer function was proposed. It was found that this model is more consistent with the analyzed data than the pure theoretical models. The results of this thesis will be useful for integrating SAR retrievals in ocean current products and assimilating SAR observables in the atmospheric, oceanic or coupled models. The results are also relevant for preparation studies of future satellite missions.
Structural Analysis of Magnesium Chloride Complexes in Dimethoxyethane Solutions in the Context of Mg Batteries Research

Recently, MgTFSI2/MgCl2 electrolyte solutions in dimethoxyethane (DME) have been shown to function as viable electrolyte solutions for secondary Mg batteries that can facilitate reversible magnesium deposition/dissolution. MgCl2 is a crucial component in these solutions. On its own, however, it is practically insoluble in DME. Therefore, the fact that it is readily dissolved in MgTFSI2/DME solution is remarkable. Addition of MgCl2 greatly improves the electrochemical performance of MgTFSI2/DME electrolyte solutions. Thus, identifying the species formed in MgTFSI2/MgCl2 solutions is intriguing. In this study, we implemented a wide variety of analytical tools, including single crystal X-ray diffraction, multinuclear NMR, and Raman spectroscopy, to elucidate the structure of these solutions. Various solution species were determined, and a suitable reaction scheme is suggested.
A Systematic Treat Model for Software-Defined Networking

Software-Defined Networking (SDN) has three key features: separation of control and forwarding, centralized control, and network programmability. While improving network management flexibility, SDN has many security issues. This paper systemizes the security threats of SDN using spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege (STRIDE) model to understand the current security status of SDN. First, we introduce the network architecture and data flow of SDN. Second, we analyze security threats of the six types given in the STRIDE model, aiming to reveal the vulnerability mechanisms and assess the attack surface. Then, we briefly describe the corresponding defense technologies. Finally, we summarize the work of this paper and discuss the trends of SDN security research.
Erklärungsansätze für das Momentum in Aktienkursen

„The trend is your friend“. Diese bekannte Börsenweisheit empfiehlt, auf die Fortdauer eines Kurstrends zu vertrauen, anstatt Kursgewinne zu frühzeitig zu realisieren. „Never catch a falling knife“ warnt indes vor dem frühzeitigen Einstieg in ein Wertpapier, dessen Kurs sich in einer Abwärtsbewegung befindet. Diese beiden populären Verhaltensregeln für Wertpapiermärkte entstammen der Beobachtung, dass sich der Kurs eines beliebigen Wertpapiers über eine gewisse Zeitdauer in dieselbe Richtung bewegen kann und sich damit ein so genanntes Momentum in den Kursen ergibt. So ist es vielleicht nicht verwunderlich, dass die Mehrheit der professionell gemanagten Investmentfonds Momentum-Strategien verfolgen, deren Erfolg auf dieser positiven Autokorrelation in den Zeitreihen der Aktienrenditen basiert. Grinblatt et al. (1995, S. 1095) bestätigen empirisch, dass mehr als 3⁄4 aller untersuchten USPublikumsfonds der Momentum-Strategie folgen und damit (im Betrachtungszeitraum von zehn Jahren) eine durchschnittlich bessere Performance als jene Portfolios erzielen, die nach anderen Strategien verwaltet werden.
Influence of hot water treatments on postharvest physicochemical characteristics of Hayward and Jintao kiwifruit slices

The effect of precutting hot water treatments on the quality of minimally processed kiwifruits was studies. Whole fruits were subjected to hot water dipping (HWD) at 45 8 C for 25 or 75 min, minimally processed, packed and stored at 0 8 C for 8 days. Weight loss, respiration rate, gas composition, texture, color, titratable acidity, pH, soluble solids content, sensory analysis, vitamin C, total polyphenols, antioxidant capacity, and microbial analysis were investigated. An overall beneficial effect of HWD 45 8 C/75 min on the postharvest quality was observed. The fruits subjected to this treatment showed lower respiration rate, maintained the initial color and presented a better visual quality compared to the control. Moreover, both in Hayward and Jintao, heat treatments inhibited the microbial growth during storage. The study selected HWD 45 8 C/75 min as the opti-mal combination to retain postharvest quality of fresh-cut kiwifruit for the cold storage period and throughout the supply chain. results indicated that
Simultaneous determination of four bioactive compounds in Korean rice wine (makgeolli) by solvent extraction coupled with gas chromatography-mass spectrometry

ABSTRACT Makgeolli is a traditional Korean rice wine reported to have anticancer, anti-inflammatory, and antioxidant effects. We developed an approach involving solvent extraction coupled with gas chromatography-mass spectrometry to determine four bioactive compounds, farnesol (FOH), squalene (SQ), and newly identified 4-vinyl guaiacol (4-VG) and 2,4-di-tert-butylphenol (DTBP), in makgeolli. The method was validated with the linearity, limit of detection, limit of quantification, intra- and inter-day precision, and accuracy. The validated method was then applied to several makgeolli, beer, and wine samples. 4-VG and DTBP were identified in all beverages, but FOH and SQ were only identified in makgeolli.
Strongly enhanced luminescence of Sr4Al14O25:Mn4+ phosphor by co-doping B3+ and Na+ ions with red emission for plant growth LEDs

Development of a more cost-effective radiation source for use in plant-growing facilities would be of significant benefit for commercial crop production applications. A series of co-doped B3+ and Na+ ions Sr4Al14O25:Mn4+ inorganic luminescence materials which can be used for plant growth were successfully synthesized through a conventional high-temperature solid-state reaction. Powder X-ray diffraction was used to confirm the crystal structure and phase purity of the obtained samples. Then scanning electron microscopy elemental mapping was undertaken to characterize the distribution of the doped ions. Detail investigations on the photoluminescence emission and excitation spectra revealed that emission intensity of tetravalent manganese ions can be well enhanced by monovalent sodium ions and trivalent boron ions under near-ultraviolet and blue excitation. Additionally, crystal field parameters and energies of states are calculated and discussed in detail. Particularly we achieve a photoluminescence internal quantum yield as high as 60.8% under 450 nm blue light excitation for Sr4Al14O25:Mn4+, Na+, B3+. Therefore, satisfactory luminescence properties make these phosphors available to LEDs for plant growth.

Application of fluorescent markers for homogeneity assessment of grain mixtures based on maize content

The paper presents test results for the assessment of the tracer content in a three-component (green peas, sorghum, maize) feed mixture that is based on the fluorescent method. The homogeneity of mixtures was determined on the basis of the maize content (as the key component), which was treated with fluorescent substance: tinopal, rhodamine B, uranine and eosin. The key components were wet-treated with fluorescent substances with different concentrations. Feed components were mixed in a vertical funnel-flow mixer. 10 samples were collected from each mixed batch. Samples were placed in a chamber equipped with UV light and, then, an image recorded as BMP file was generated. The image was analysed by means of the software programme Patan. On the basis of the analyses conducted, data on the maize content marked with a fluorescent marker were obtained. Additionally, the content of the key component was determined in a conventional manner – using an analytical scale. Results indicate the possibility of using this method for homogeneity assessment of the three-component grain mixture. From these tests, fluorescent substances that can be applied in the case of maize as a key component, together with their minimum concentrations, were identified: tinopal 0.3%, rhodamine B 0.001%.
