Thermodynamic and exergic modelling of a combined cooling, heating and power system based on solid oxide fuel cell

In this research, thermodynamic and exergic analyses have been carried out on a combined cooling, heating and power cogeneration system that includes a solid oxide fuel cell and a single-effect lithium bromide absorption chiller. Results indicate that by increasing the system inlet air flow rate, the overall efficiency of the hybrid system is reduced, due to the reduction of the cell’s working temperature and exhaust gases temperature; while an increase in the working pressure of the system has no effect on its efficiency. The results also show that by raising the temperature of exhaust gases, the rate of exergy destruction diminishes, while the rate of exergy loss in the hybrid system increases. In the absorption chiller cycle, the maximum exergy destruction rate occurs in the generator, and the minimum rate is achieved in the pressure-reducing valve, between the evaporator and the condenser. Also, in the fuel cell cycle, the highest exergy destruction rate occurs in the heat exchanger of the inlet air to the cell, and the lowest exergy destruction rate occurs in the two water pumps. Moreover, the entropy generation rate and the exergy destruction rate of the fuel cell cycle are higher than those of the chiller cycle.

Co-Solubilization of the Binary Mixture of 1-Naphthol and 2-Naphthol in the Water Micellar Solution of Sodium Cholate and Cetyltrimethylammonium Bromide

The micellar co-solubilization of alpha- and beta-naphthol and their binary mixture with surfactants sodium cholate (SC) and cetyltrimethylammonium bromide (CTAB) is examined. The micellar solubilization of 2-naphthol (2NpOH) in SC is entropic, and it is an energetically more favored process than the micellar solubilization of 1-naphthol (1-NpOH). The capacity of the solubilization by CTAB for solubilizing 1- and 2-naphthol is about eight-times higher at 4CMC than at 2CMC (four- and two-times the critical micelle concentration, respectively), which can be explained by the change in the micelle structure with an increase in the total concentration of the CTAB surfactant. For the same CMC values of the examined surfactants, SC has a higher solubilization capacity for naphthols in comparison to the solubilization capacity of CTAB, which is explained by the existence of hydrogen bonds between the building units and solubilizates that are formed in the SC micelles. For each molar ratio of the micellar binary mixture of 1- and 2-NpOH and in both examined surfactants (except for SC solubilization with a = 0.1 and a = 0.9 at 4CMC), the interaction parameters for 1- and 2-NpOH are larger than zero, which means there is a mutual antagonistic effect of 1- and 2-naphthol on their micellar co-solubilization that is probably the consequence of the competition for the same spatial part of the hydrophobic domain of the examined micelles. The binary mixture of 1- and 2-NpOH in the micellar pseudophase possesses a higher Gibbs free energy content and is thermodynamically less stable than the monocomponent solubilizates in SC and CTAB micelles.

Diethylaminophenyl-based Schiff base Cu(II) and V(IV) complexes: experimental and theoretical studies and cytotoxicity assays

An N,N,O,O donor Schiff base blocking ligand [H2L = 6,6′-((1E,1’E)-(ethane-1,2-diylbis(azaneylylidene))bis(methaneylylidene))bis(3-(diethylamino)phenol), 1] has been used to synthesize mononuclear [CuL]center dot H2O (2) and [VO(L)] (3) complexes. The ligand and complexes have been characterized by elemental, spectral (FTIR and UV-vis) and thermogravimetric analysis. The molecular structures of 1 and 2 have been confirmed by single crystal X-ray diffraction studies. The crystal structure of the ligand (1) indicates that the molecule is sited on a crystallographic inversion centre and the planar conformation of the salicylideneimine moiety is favored by two intramolecular O-HN center dot center dot center dot 1 hydrogen bonds forming S(6) ring motifs. The copper(ii) center in complex 2 is coordinated in a square planar fashion. The presence of an extended pi-system in the complex (two chelate rings and two phenyl rings) facilitates the formation of chelate ring (CR)center dot center dot center dot pi non-covalent interactions. DFT calculations have been performed to explore the energetic features of unconventional CR center dot center dot center dot pi and hydrogen bonding interactions that are observed and described in the solid state of 2. Moreover, we have studied how the energy of the CR center dot center dot center dot pi interaction is influenced by the substituent of the phenyl ring. In addition, the cytotoxic effect of the compounds has been tested against MG-63 (human osteosarcoma), HT-29 (human colorectal) and MCF7 (breast) cancer cell lines using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.

Facile RbBr interface modification improves perovskite solar cell efficiency

High-performance hybrid perovskite solar cell (PSC) is an emerging generation of energy material by virtue of its excellent properties such as wide light absorption range, large electron diffusion length, and small exciting energy. However, to date, methods of perovskite deposition generally do not offer desired film coverage, resulting in the direct interfacial contact, which seriously deteriorates the photovoltaic performance of devices. To improve the interfacial functions of the perovskite layer (PL)/electron transport layer (ETL) of the PSC devices, rubidium bromide (RbBr) is applied as a facile interfacial modifier. It is sandwiched between ETL tin oxide (SnO2) and PL [Cs-0.05(MA(0.17)FA(0.83))(0.95)Pb(I0.83Br0.17)(3)] to a fabricate a planar PSC. The RbBr modification of the PSC fluorine-doped tin oxide/SnO2/(RbBr)/PL/spiro-OMeTAD/Au (2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spiro-bifluorene) can reduce the energy barrier at the ETL/PL interface, improve the electronic contact between PL and ETL, and accelerate the electron extraction process. The RbBr modification thus leads to a higher power conversion efficiency of 18.29% for the PSC, as compared with 16.03% without RbBr modification. The facile RbBr modification procedure and significant performance advancement pave the way for future energy studies. (C) 2019 Elsevier Ltd. All rights reserved.

Preparation of the Serotonin Transporter PET Radiotracer 2-({2-(Dimethylamino)methyl]phenyl}thio)-5-[F-18]fluoroaniline (4-[F-18]ADAM): Probing Synthetic and Radiosynthetic Methods

Serotonin transporters (SERTs) are involved in regulating the concentration of synaptic serotonin and present a good target for many neurologic and psychiatric disorder drugs. Positron-emission tomography (PET) is a valuable tool in both diagnosis and monitoring treatment therapies, and hence much effort is being given to developing suitable PET agents for imaging SERT. Our interest in applying the fluorine-18 analogue 4-[ (18) F]ADAM for imaging SERT prompted the development of an improved synthetic route to access unlabelled ADAM. This is achieved using Pd-catalysed coupling with thiosalicylic acid and an EDC/HOBt amide coupling in 36% yield over 4 steps. A novel radiolabelling precursor, the pinacol-derived boronic ester, is prepared from the bromide using the Miyaura borylation and is obtained in 27% yield over 6 steps. Pinacolate is then used for the radiolabelling of 4-[ (18) F]ADAM based on Cu-mediated nucleophilic fluorination in which the presence of oxygen is critical for the reaction. A 1:1 substrate to copper ratio is found to be optimal when the reaction is performed in dimethylacetamide at 85 degrees C. Using these conditions, 4-[ (18) F]ADAM is prepared in 29 +/- 10% (n = 6) radiochemical conversion after hydrolysis of the Boc group with HCl. Furthermore, the method is successfully automated to afford 4-[ (18) F]ADAM in 10% radiochemical conversion.

Efficacy of alkyltrimethylammonium bromide for decontaminating salt-cured hides from the red heat causing moderately halophilic bacteria

Conventionally, animal hide and skin necessitates 95% saturated brine solution (SBS) for its preservation. This salt is primarily derived from different sources including solar-saltern, evaporation ponds, etc., which are laden with different types of halophilic micro-organisms. Previous studies confirmed that the presence of moderately halophilic bacteria caused red heat on cured hide, which adversely affects the leather quality and causes substantial economic losses for leather industries. Thus, this investigation was carried out to examine the effects of different concentrations of alkyltrimethylammonium bromide (ATMB) on selected halophilic-bacteria attributed to the deterioration of hide quality. In nutrient broth solution (NBS), ATMB at 250 and 500 ppm reduced individual halo-bacteria, that is, Halomonas halodenitrificans, Halomonas eurihalina, Alkalibacillus haloalkaliphilus and Salimicrobium album, by averages of 0 center dot 64 and 1 center dot 90, 1 center dot 5 and 2 center dot 61, 0 center dot 90 and 2 center dot 27, 1 center dot 65 and 3 center dot 36 log CFU per ml respectively in 5 min. ATMB treatment in SBS at 500 ppm for 18 h resulted in a reduction of H. halodenitrificans, H. eurihalina, A. haloalkaliphilus and S. album by averages of 1 center dot 9, 1 center dot 25, 0 center dot 96 and 1 center dot 34 log CFU per ml respectively, when compared with the controls. Likewise, 5000 ppm ATMB reduced the cocktail population nearly to zero from that cultivated in SBS for 18 h.

Melatonin inhibits high glucose-induced ox-LDL/LDL expression and apoptosis in human umbilical endothelial cells

Background: Cardiovascular disease (CVD) is one of the major cause of mortality in diabetic patients. Evidence suggests that hyperglycemia in diabetic patients contributes to increased risk of CVD. This study is to investigate the therapeutic effects of melatonin on glucose-treated human umbilical vein endothelial cells (HUVEC) and provide insights on the underlying mechanisms. Materials and methods: Cell viability was determined using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Reactive oxygen species (ROS) and membrane potential was detected using 2′,7′-dichlorofluorescein diacetate and 5,5′,6,6′-tetrachloro-1,1′,3,3′–tetraethylbenzimidazolcarbocyanine iodide (JC-1) dye staining, respectively. While, cell apoptosis was determined by Annexin-V staining and protein expression was measured using Western blot. Results: Our results suggested that melatonin inhibited glucose-induced ROS elevation, mitochondria dysfunction and apoptosis on HUVEC. Melatonin inhibited glucose-induced HUVEC apoptosis via PI3K/Akt signaling pathway. Activation of Akt further activated BcL-2 pathway through upregulation of Mcl-1 expression and downregulation Bax expression in order to inhibit glucose-induced HUVEC apoptosis. Besides that, melatonin promoted down-regulation of oxLDL/LOX-1 in order to inhibit glucose-induced HUVEC apoptosis. Conclusions: In conclusion, our results suggested that melatonin exerted vasculoprotective effects against glucose-induced apoptosis in HUVEC through PI3K/Akt, Bcl-2 and oxLDL/LOX-1 signaling pathways.

Investigation of the mechanical properties of Ni-B/hBN composite coatings electrodeposited in presence of CTAB as the surfactant

The effect of hexadecyltrimethylammonium bromide (CTAB) concentration on the galvanostatic electrodeposition of Ni-B matrix nano hexagonal boron nitride (hBN) reinforced composite coatings was investigated. XRD and FE-SEM analyzes were used for crystallographical and morphological investigations, respectively. Vickers indentation, nanoindentation, and nanoscratch experiments were carried out to investigate the micromechanical, nanomechanical and tribological properties, respectively. Potentiodynamic polarization and electrochemical impedance spectroscopy techniques were applied for corrosion characterization. The investigated properties have been improved with the increasing CTAB concentrations up to 900 mu M. In a general manner, CTAB has a beneficial effect at lower concentrations and can be useful for metal matrix nano ceramic reinforced composite coating electrodeposition in the lower concentration range.

Optically and Structurally Stabilized Plasmo-Bio Interlinking Networks

Visualization of dynamic interlinking networks which respond and adapt to the constantly changing environment would be highly beneficial in developing new composite materials and active/responsive materials. Here, optically and structurally stabilized plasmo-bio interlinking networks (PBINs) free from photobleaching for high resolution, long term visualization are reported. Necessary for structural and optical stability, a new stability algorithm to comprehensively quantify stability and detect minute instability undetectable by traditional methods is introduced. Biocompatible plasmonic gold nanorods (Bio-AuNRs) are synthesized for high resolution, long term imaging by utilizing bromide-free alternatives to achieve CTA+ free. Systematic physical, chemical, and biological characterizations reveal the structural and optical stability of Bio-AuNRs required for constructing PBIN. Lastly, with actin as a model of interlinking networks of the cytoskeleton, optically and structurally stable PBIN (100% CTA+ free, 97% crosslinking rate) in applications as active/responsive materials, are demonstrated.
