Contaminant transport in natural sediments: influence of soil organic matter and Fe/Al-oxyhydroxides on heavy metals (Cu, Zn) and nanoparticles (titanium dioxide)

Contaminant transport in subsurface environments may be significantly influenced by contents of aquifer sediments, such as soil organic matter (SOM) and Fe/Al-oxyhydroxides, though their effects are not fully known. This thesis systematically explored the influences of SOM and Fe/Al-oxyhydroxides on two common groundwater contaminants, engineered nanoparticles (titanium dioxide nTiO2) and heavy metals (Cu and Zn), in two projects using the same natural sediment. Project 1 found dissolved SOM enhanced nTiO₂ transport by adsorbing onto nTiO₂ surface and stabilizing it in suspension, whereas solid SOM and Fe/Al-oxyhydroxides reduced transport by attracting nTiO₂ when surface charges were opposite. In project 2, Cu adsorption was strongly dependent on SOM and Fe/Al-oxyhydroxide content, with lesser effects for Zn. Depleted SOM decreased adsorption when pH was 6.5. Both projects contributed to knowledge of the roles of SOM and Fe/Al-oxyhydroxides in governing contaminant transport in natural sediments.
Molybdenum Oxide Nanosheets with Tunable Plasmonic Resonance: Aqueous Exfoliation Synthesis and Charge Storage Applications

Herein, a simple aqueous‐exfoliation strategy is introduced for the fabrication of a series of MoO3−x nanosheets (where x stands for oxygen vacancies) using two commercial molybdenum oxide precursors, MoO2 and MoO3. The nanosheets offer a localized surface plasmon resonance (LSPR) effect which is dependent on the structure and local environment of the nanosheets. The LSPR can be efficiently tuned by changing the weight ratio between the molybdenum oxide precursor(s) and/or by solar light irradiation using a low‐energy UV lamp (36 W). For the pristine MoO3−x nanosheets, the highest LSPR signal is obtained for nanosheets prepared using 80% MoO2. On the contrary, after solar light irradiation, the nanosheets prepared using pure MoO3 offer the highest LSPR response. The nanosheets also show an outstanding rate capability when used as binder‐free supercapacitor electrodes in an acidified Na2SO4 electrolyte. The electrodes exhibit discharge capacities of 110 and 75 C g−1 at a scan rate of 20 and 1000 mV s−1, respectively. The MoO3−x nanosheets can likewise be used as a negative electrode material for lithium‐ion batteries. The efficient eco‐friendly synthesis and the ability to tune the photochemical and electrochemical properties of the nanosheets make this approach interesting to many energy‐related research fields.
Fabrication and characterization of novel Ag2O-polyimide composites with enhanced visible-light photocatalytic activity

Abstract Novel high-efficiency visible-light photocatalyst, silver oxide (Ag2O)-polyimide (PI) photocatalyst is synthesized by a liquid phase reaction method. The obtained samples are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared spectra (FT-IR) and photoluminescence (PL). The photocatalytic activity of the Ag2O-PI composites are evaluated by the decomposition of Rhodamine B (RhB) under visible-light irradiation. All Ag2O-PI composite possesses higher photocatalytic activity than pure Ag2O and PI. It could be found that RhB was photodegraded with the highest degradation efficiency of 97.9% when the mass ratio of Ag2O and PI reached to 2:1. This enhancement can be attributed to the efficient separation of photogenerated electron and holes. Furthermore, the possible mechanism for the photocatalytic activity of Ag2O-PI composites was also proposed.
An Experimental Study of Photocatalytic Degradation of Congo Red Using Polymer Nanocomposite Films

Eco-friendly polymer nanocomposite films were synthesized using biodegradable polymers of chitosan and polyvinyl alcohol as polymeric matrices and carbon black nanoparticles as the reinforcement. These films were applied to study their applicability to industrial wastewater purification as a photocatalyst for degradation of Congo red as a target pollutant and to study the effect of the polymeric matrix types of the films on their performance as a semiconductor photocatalyst. Fourier-transform infrared (FT-IR) spectra and X-ray diffraction (XRD) were used to characterize the films. Visible light photocatalytic degradation of Congo red as a pollutant under various operational conditions of pH, dye concentration, contact time, and light intensity was performed. Photocatalytic results revealed that the polymeric substrate type does not play a major role in the photodegradation of the dye, and the best operational conditions were at a pH of 6 and a dye solution concentration of 8 mg/L.

Preparation of bio-functional textiles by surface functionalization of cellulose fabrics with caffeine loaded nanoparticles.

In recent years transdermal drug delivery has aroused significant interest as a sustained and non-invasive way of administering active substances. The advancements of nanotechnology allowed the development of novel pharmaceutical formulations overcoming skin barrier. Furthermore, such nano-system can be combined with conventional fabrics to pave the way to a new generation of wearable drug delivery devices: bio-functional garments. First the NP were produced by flash nanoprecipitation technique (FNP), the production process was optimized to produce particles with suitable size for transdermal applications. The nanoparticles were characterized in terms of drug content by UV-visible spectroscopy and in term of antioxidant activity by Electron Paramagnetic Resonance spectroscopy (EPR) coupled with spin trapping technique. The NPs were used to functionalize cotton and viscose-micromodal fabrics and the transdermal release properties were tested in vitro by Franz’s Cell experiment. FNP was proven to be an effective technique to produce tunable size particles. Moreover, the nanoencapsulated drug exhibited antioxidant activity. The Franz’s Cell test evidenced a controlled release behavior, providing evidence that the bio-functional textile is suitable for applications where sustained release and antioxidant properties are required.
Équations d'état des produits de détonation des explosifs solides

Le calcul des caracteristiques de detonation d’un explosif solide requiert l’utilisation d’equations d’etat pour modeliser le comportement des produits de detonation. Cependant, les pressions et les temperatures auxquelles sont soumis ces produits rendent difficile la mise au point d’une equation d’etat valide de la centaine de kilobars a la centaine de bar si l’on souhaite couvrir l’ensemble des effets d’une detonation. Les nombreuses recherches effectuees dans ce domaine ont abouti a l’elaboration d’un grand nombre d’equations d’etat a caractere plus ou moins theorique ou empirique. Malheureusement aucune d’elle ne s’est revelee etre entierement satisfaisante. Dans ces travaux nous nous interessons au domaine de validite a basse pression de l’equation d’etat JWL implementee dans les codes d’hydrodynamique et de l’equation BKW utilisee dans les codes de thermochimie pour les produits des materiaux energetiques sous oxygenes. La premiere equation d’etat considere le melange des produits a une echelle macroscopique tandis que la seconde assure une description plus fine du melange en considerant les differentes phases presentes. En effet, les produits de detonation comprennent en plus des molecules simples des particules solides de carbone. A cette fin, une etude numerique et experimentale a ete menee pour deux compositions explosives : la Composition B (RDX/TNT) et l’octoviton (HMX/Viton). Des experimentations d’adaptation d’impedance entre des materiaux energetiques et des materiaux inertes ont ete realisees afin de detendre les produits de detonation de la centaine de kilobars a quelques bars. Ce dispositif est instrumente avec des metrologies innovantes dans le domaine de la detonique. La spectrometrie d’emission ultra rapide est utilisee pour effectuer l’analyse spectrale des produits de detonation au cours de leur detente dans le domaine spectral du visible. Deux signatures thermiques sont identifiees sur les spectres obtenus : l’une liee au rayonnement des gaz ionises, l’autre liee au rayonnement des particules solides de carbone. L’interferometrie haute frequence permet un enregistrement continu de la propagation du choc dans les differents milieux (explosif, materiau inerte). Ces experiences font l’objet de simulations numeriques avec le code d’hydrodynamique Ouranos et le code de thermochimie SIAME du CEA. Les resultats experimentaux et numeriques concordent jusqu’a des pressions de l’ordre du kilobar. Ces deux mesures permettent d’avancer dans la validation de l’equation d’etat des produits de detonation implementee dans les codes numeriques.
Protein-induced fluorescence enhancement for a simple and universal detection of protein/small molecule interactions

We herein describe a novel and efficient method for the detection of protein/small molecule (SM) interactions, which relies on the protein-induced fluorescence enhancement (PIFE). In this method, a duplex probe is designed to position Cy3 and SM at the optimal distance to maximize the effect of PIFE, which is utilized as the key component. In the presence of target proteins that bind to SM, the Cy3 is guided close to the target proteins, which significantly enhances the fluorescence signal through a process of PIFE. With this approach, we successfully analyzed a model target protein, streptavidin (STV) that interacts with biotin (BTN) in less than 10 min without any washing steps. In addition, the practical applicability of this method was demonstrated by reliably determining STV in human serum. Finally, the universal applicability of this method was demonstrated by monitoring the interaction between folate and folate receptors.
A brief review on graphene applications in rechargeable lithium ion battery electrode materials

Graphene is a single atomic layer of carbon atoms, and has exceptional electrical, mechanical, and optical characteristics. It has been broadly utilized in the fields of material science, physics, chemistry, device fabrication, information, and biology. In this review paper, we briefly investigate the ideas, structure, characteristics, and fabrication techniques for graphene applications in lithium ion batteries (LIBs). In LIBs, a constant three-dimensional (3D) conductive system can adequately enhance the transportation of electrons and ions of the electrode material. The use of 3D graphene and graphene-expansion electrode materials can significantly upgrade LIBs characteristics to give higher electric conductivity, greater capacity, and good stability. This review demonstrates several recent advances in graphenecontaining LIB electrode materials, and addresses probable trends into the future.
Biochemical role of phytoestrogen (Chrysin) against N-methyl nitrosourea (NMU)- induced proliferative lesions in mammary glands of postmenopausal female rat

This study aimed to investigate the role of the phytoestrogen (chrysin) in the treatment or protection of NMU-induced preneoplastic lesions in mammary glands of postmenopausal female rats. Rats (n=105) were divided into seven groups (n=15/group); group1(negative control group). Groups 2&3 (positive control groups), rats were injected intraperitoneally (i.p.) with 4 doses of NMU (75 mg/kg b.w.,once/5days) before or after oral administration of glycofurol. Groups 4 &5(treatment groups),rats received 4 doses of NMU (75 mg/kg b.w., once/5days,i. p.), left for 6 weeks then followed by 3 doses, per week, of chrysin (125 or 250 mg/kg b.w., orally; p.o), respectively, for another 6 weeks. Groups 6 & 7(protective groups), rats received 3 doses, per week, of chrysin(125 or 250 mg/kg b.w.,p.o.), for 6 weeks then followed by 4 doses of NMU (75 mg/kg b.w., once/5days, i.p.) then left for another 6 weeks. The NMU injection caused significant decrease in PLT count, lymphocytes %, Hb, MCH, MCHC, E2, TAC levels as well as GST and CAT activities. The results also showed that NMU significantly elevated WBC count, granulocytes%, monocytes %, MCV, RDW%, CRP, CEA levels and arginase activity. Either treatment or protection with chrysin modulated the adverse effects of NMU and ameliorated the change in the biochemical parameters. The biochemical observations were also confirmed by histological studies. In conclusion, phytoestrogens may relieve the severity of postmenopausal pre-cancerous disorders, especially when consumed in high dose for a while before the incidence of lesions.

EARLY DETECTION OF HELLP SYNDROME USING BIOLOGICAL MARKERS AND DOPPLER ULTRASONOGRAPHY

Purpose: To determine the relationship between pregnancy-associated plasma protein-A (PAPP-A) levels and uterine Doppler ultrasonography for the prediction of severe preeclampsia (PE) and HELLP syndrome at the last trimester. Methods: Two groups were constructed; severe preeclampsia group consisted of 38 women; HELLP Syndrome group consisted of 12 women. Both groups were matched strictly for gestational age at last trimester. Maternal blood sample for PAPP-A was collected and uterine Doppler ultrasonography was performed as soon as any woman under the study was diagnosed as severe preeclampsia or HELLP syndrome at last trimester and compared. Results: Mean ages of participants, Parity, gestational weeks and fetal weights were similar. Mean PAPP-A levels were significantly higher in severe preeclampsia and HELLP groups. There was a statistically significant difference regarding Resistive Index (RI) (P<0.001) and Pulsatility Index (PI) (P=0.005) between cases presenting with severe preeclampsia and HELLP groups. Conclusion: PAPP-A levels could provide prediction for severe preeclampsia and HELLP syndrome at last trimester. Increased uterine artery resistance in the third trimester of pregnancy could be used to predict maternal complications including severe preeclampsia and HELLP syndrome.
Anti-Cancer Properties Of Cinnamon Oil And Its Active Component, Trans-Cinnamaldehyde

Bioactive dietary agents (i.e., nutraceuticals) have shown the ability to slow or eliminate cancer growth with marked immediate effects when applied directly to cancer cells. By isolation and inspection of the effective components in these therapeutic agents, with respect to cancer cell inhibition, a clear mechanism of action can contribute to a better understanding of the benefits of these natural products. Here we have examined the effects of three essential oil formulations of nutraceutical agents: Frankincense, Garlic and Cinnamon, and ultimately investigated trans-cinnamaldehyde (TC), the active ingredient in cinnamon oil and a documented anti-inflammatory and anti-cancer agent, on cell viability and migratory potential in in vitro models of breast cancer representing different tumorigenic and metastatic potential. Results show that TC exhibits a clear dose-response relationship in inhibiting cancer cell survival and migration in a breast cancer aggression-dependent manner. Our results suggest that TC may be a promising candidate for the development of effective strategies to counter breast cancer in vivo by reducing or eliminating its progression.
Novel triangular silver nanoparticle modified membranes for enhanced antifouling performance

This study marks the first ever attempt at the successful fabrication of a novel reactive membrane to combat fouling through layer-by-layer (LBL) surface modification with polyelectrolyte (PE), followed by anisotropic triangular silver nanoparticles (TSNP). The morphology and the presence of TSNP on the membrane was confirmed by HR-TEM, FE-SEM and XPS. The charge density of the novel membrane (PE-TSNP) was increased 15.6 fold, as a result of the sharp-tip morphology of the TSNP forming tip-based “hot spots” on the membrane surface and high-atom-density active facets, which also enhanced the membrane hydrophilicity by 36%. Owing to these improved features, the novel membrane displayed remarkable antibacterial and anti-adhesion properties by achieving 100% bactericidal effect against high initial bacterial concentration (107 CFU mL−1). The membrane flux was improved by 31% while retaining a high flux recovery rate of 98.2% against biofouling. The membrane also mitigated organic and bio-organic fouling by maintaining high flux recovery rates of 96% and 95% respectively. As compared with a spherical silver nanoparticle modified membrane (PE-SSNP), the PE-TSNP membrane was 25.7% more hydrophilic and achieved 10% higher bacterial killing. Moreover, the novel membrane displayed 9.5%, 11.6%, and 14% higher flux recovery rates than that of the PE-SSNP membrane against biofouling, organic and bio-organic fouling respectively. Furthermore, the novel membrane retained a long-term biocidal capability of 93% even after 4 months of successive tests. ICP-MS revealed silver ion leaching of 4 μg L−1 and the total silver loss of 14% from the PE-TSNP membrane after 14 days.
QSAR APPROACH TO ESTIMATING THE ANALGESIC ACTIVITY OF A SERIES OF TRI-SUBSTITUTED PYRIMIDINE DERIVATIVES

In the search for new molecules with improved analgesic activity, a series of twenty tri-substituted pyrimidine derivatives were subjected to a QSAR study. This study was conducted using Pearson Correlation Coefficients, Principal Component Analysis (PCA), Hierarchical Ascending Classification (HAC) and Multiple Linear Regression. The model obtained correlates the analgesic activity expressed by logAA, the energy of the highest occupied molecular orbital , the dipole moment and the lipophilic coefficient ACD/logP. Statistical indicators R2 = 91.55%; RMSE = 0.2592; F = 39.720; = 0.858 and =0.765, establish the internal performance and stability of the model. While its external predictive ability has been proved by the statistical parameters = 0.727 and = 0.403. The domain of applicability of the model developed, determined by the technique of levers and standardized residues, did not present any aberrant observations. The model thus established made it possible to determine the structures of eleven new tri-substituted pyrimidine derivatives having a better analgesic activity than the study molecules, at the dose of 10 mg/kg of body weight.
Distributed Data-Driven Power Iteration for Strongly Connected Networks

This paper presents data-driven power iteration to distributively estimate the dominant eigenvalues of an unknown linear time-invariant system. The proposed strategy only requires a single trajectory data or measurements. Furthermore, in order to perform the distributed estimation, the communication network topology can be chosen to be any strongly connected directed graphs. The proposed data-driven power iteration is demonstrated using several numerical examples and is then applied to estimate the generalized algebraic connectivity of cooperative systems and to control the epidemic spreading.
Embedding Microbial Fuel Cells into the Vertical
Flow Constructed Wetland Enhanced
Denitrogenation and Water Purification

Constructed wetlands have been extensively applied for treating drinking water sources and other water bodies that are not severely polluted due to their low construction and operation costs. In this regard, microbial fuel cells (MFC) could potentially achieve both energy generation and wastewater purification, though the construction cost is high. Based on the bio-electrochemical theory, a novel device of the integrated vertical flow constructed wetland (IVCW) embedded with MFC (IVCW-MFC) was designed and built for treating the slightly-polluted source waters with relatively high nitrogen and low carbon, where denitrification was usually hindered. Both water purification performance and electrical characteristics were examined in this system. It was observed that the maximum output voltage and power density could reach 777 mV and 8.05 mW·m-2, respectively, when the external resistance was 6000 Ω. With a better denitrification effect, the system exhibited a more effective removal of chemical oxygen demand (COD) and nitrate. The maximum efficiency of total nitrogen (TN) removal was as high as 97.35%, while the average removal efficiency was around 70%, even with a load of TN, 3.3 mg/L on average, in the influent. Furthermore, the macrophytes grew normally in the constructed wetland without any influence.
