1. “Half-Sandwich”/RuII Anticancer Complexes Containing Triphenylphosphine and p-Substituted Benzoic Acids
Mononuclear and binuclear RuII/arene/triphenylphosphine complexes with p-substituted benzoic acid derivatives were prepared and characterized. These monocationic complexes of type [Ru(η6-p-cymene)(PPh3)L] (L = benzoic acid (1), p-hydroxybenzoic acid (2), p-nitrobenzoic acid (3) and terephthalic acid (4)) were characterized using various techniques, such as

2. Effect of Suture on Mechanical Properties of Stitched Thermal Protection Sandwich
This paper investigates the tensile properties and bending performances of stitched thermal protection structure in engineering, and the effect of stitching density on mechanical properties, via a model of ceramic-aerogel stitched sandwich. With the help of ANSYS, titanium alloy bottom plate was added to the bottom surface of the thermal protection structure

3. Effect of Pile Orientation on the Shear Strength of Stitched Foam Sandwich Panel
Stitched foam sandwich panel is a newly developed sandwich structure used in various structural applications. The sandwich skins are made of glass-fiber/epoxy-matrix composite; their interior layers are connected with glass yarn called piles. This paper investigates the effect of pile orientation on the shear strength of stitched foam sandwich panel. Four ty

4. Practical Approaches of Inducing Controlled Simulated Resin Starvation Areas into Vacuum Infusion Processed Sandwich Composites Used for Characterisation of the Surface Defects and their Outcomes
Abstract Manufacturing defects in the sandwich structures have significant impact on their ultimate strength performance. It is essential to codify some criteria for the effects of such defects on the performance of the structure in order to investigate the quality of sandwich compo-sites and their load-bearing capabilities. By means of such criteria, one ca

5. Mechanical Properties Evaluation of the Carbon Fibre Reinforced Aluminium Sandwich Composites
AbstractSandwich laminates play an important role in industries and they are used in varieties of engineering applications. In the present investigation, carbon fiber reinforced aluminium sandwich laminates are fabricated and their properties such as tensile, flexural and impact are studied for their use in structural applications. All the tests are carried

6. Stochastic multi-scale analysis of homogenised properties considering uncertainties in cellular solid microstructures using a first-order perturbation
Randomness in the microstructure due to variations in microscopic properties and geometrical information is used to predict the stochastically homogenised properties of cellular media. Two stochastic problems at the micro-scale level that commonly occur due to fabrication inaccuracies, degradation mechanisms or natural heterogeneity were analysed using a sto

7. Mimotopes selected by biopanning with high-titer HIV-neutralizing antibodies in plasma from Chinese slow progressors
OBJECTIVE: One approach to identifying HIV-1 vaccine candidates is to dissect the natural antiviral immune response in treatment-naïve individuals infected for over ten years, considered slow progressor patients (SPs). It is suspected that SP plasma has strongly neutralizing antibodies (NAb) targeting specific HIV viral epitopes. METHODS: NAbs levels of 11

9. Clonagem, expressão, purificação e estudos estruturais dos domínios de reconhecimento de carboidratos (CRDs) da galectina-4 humana / Cloning, expression, purification and structural studies of the carbohydrate-recognition domains (CRDs) of human galectin-4
The galectin family comprises a group of lectins where the carbohydrate-recognition domains (CRDs) display specific affinity for ß-galactosides. They are widely distributed in normal and neoplasic cells of different organisms and are involved in a great diversity of cellular mechanisms. The galectins have been focus of recent studies, mainly for their invol

10. Sandwich structures analysis : design parameters / Analise de estruturas sanduiche : parametros de projeto
The sandwich structures have aroused great interest and have already been very widespread in several branches in industries, such as in the aerospace, military, naval and civil construction industries. This is due to their property to combine both high bending rigidity and the low weight, resulting in a very efficient structure. Thus, the analysis and also t

11. Self-assembly of supermolecular species directed by hydrogen bonding and aromatic π-π stacking interactions
A new Cu(II) trimers, [Cu3(dcp)2(H2O)8]. 4DMF, with the ligand 3,5-pyrazoledicarboxylic acid monohydrate (H3dcp) has been prepared by solvent method. Its solid-state structure has been characterized by elemental analysis, thermal analysis (TGA and DSC), and single crystal X-ray diffraction. X-ray crystallographic studies reveal that this complex has extended

12. Efeito da fotocondução em diodos com camada ativa de derivados de poli(p-fenileno vinileno) (PPV) / Photoconduction effect in single layer diodes based on PPV derivatives.
This thesis is a study about photoconductivity in polymeric materials, in particular diodes with single-layer sandwich structure derivates of poly(para-phenylene vinylene) (PPV): OC10-PPV, SY and MEH-PPV. Different metallic electrodes were deposited on the same polymeric layer. Therefore, it was necessary to realize the devices fabrication process step by st
