Bile salts and derivatives: Rigid unconventional amphiphiles as dispersants, carriers and superstructure building blocks 

Galantini, Luciano; Di Gregorio, Maria Chiara; Gubitosi, Marta; Travaglini, Leana; Vázquez Tato, José; Jover Ramos, Aida; Meijide del Rio, Francisco Angel; Soto Tellini, Victor Hugo; Viorel Pavel, Nicolae (2015)
Steroidal surfactants like bile salts have a rigid amphiphilic structure significantly different from the typical head–tail one. As a result, these molecules show peculiar features in their self-assembly behavior and ...

Light Reflection by Cuticles of Chrysina Jewel Scarabs: Optical Measurements, Morphology Characterization, and Theoretical Modeling 

Vargas Castro, William E.; Hernández Jiménez, Marcela; Libby Hernández, Eduardo; Azofeifa Alvarado, Daniel E.; Barboza Aguilar, Cinthya; Solís Blanco, Ángel Arturo (2016)
Cuticles of some Chrysina scarabs are characterized by flat, graded, and twisted structures of nanosized chitin fibrils. As inferred from SEM images, each species has its own spatial period or pitch P which is dependent ...

Heterogeneous Water Oxidation: Surface Activity versus Amorphization Activation in Cobalt Phosphate Catalysts 

González Flores, Diego; Sánchez Villalobos, Irene; Zaharieva, Ivelina; Klingan, Katharina; Heidkamp, Jonathan; Chernev, Petko; Menezes, Prashanth W.; Driess, Matthias; Dau, Holger; Montero Villalobos, Mavis Lili (2015)
Is water oxidation catalyzed at the surface or within the bulk volume of solid oxide materials? This question is addressed for cobalt phosphate catalysts deposited on inert electrodes, namely crystallites of pakhomovskyite ...

Influence of nanosilica and diatomite on the physicochemical and mechanical properties of binder at unaged and oxidized conditions 

Baldi Sevilla, Alejandra; Montero Villalobos, Mavis Lili; Aguiar Moya, José Pablo; Loría Salazar, Luis Guillermo (2016)
Modification of binders helps address common distresses in pavements by changing their essential properties. In order to further characterize the role of additives in these changes, a set of nanosilica and diatomite modified ...

Synthesis and characterization of new mixed-valent Mn(II)/Mn(III) and mixed metal Ni/Mn complexes 

Ledezma Gairaud, Marisol; Pineda Cedeño, Leslie William; Aromí, Guillem; Sañudo, E. Carolina (2015)
Microwave assisted synthesis and bench-top reactions are compared for Mn and Mn/Ni reaction systems with substituted salicylic acid (2-hydroxy-6-isopropyl-3-methylbenzoic-acid (SALOH2). When Mn salts are used, the microwave ...

Crystal structures and biological activity of 1,1,4-tri­phenyl-substituted 1,3-enyne com­pounds 

Pineda Cedeño, Leslie William; Arias Echandi, María Laura; Cabezas Pizarro, Jorge A. (2019)
1,3-Enyne structural motifs are versatile building blocks in organic synthesis and occur widely in various natural products with many of them being highly active as cytotoxic macrolides and antitumour antibiotics. This ...

Co-adsorbing effect of bile acids containing bulky amide groups at 3β-position on the photovoltaic performance in dye-sensitized solar cells 

Soto Navarro, Andrea; Alfaro Vargas, Ariel; Soto Tellini, Victor Hugo; Moehl, Thomas; Barea, Eva M.; Fabregat Santiago, Francisco; Pineda Cedeño, Leslie William (2019)
Co-adsorbing molecules attain certain control in the surrounding of the dyes leading to enhanced efficiencies mainly by affecting the recombination of the photogenerated electrons and aggregation of dyes. Bile acids ...

Bis(μ2-benzoato-κ2O,O′)bis­(benzoato-κO)bis(ethanol-κO)bis­(μ3-hydroxido)hexa­kis­(μ-pyrazol­ato-κ2N,N′)hexa­copper(II) ethanol disolvate 

Ledezma Gairaud, Marisol; Pineda Cedeño, Leslie William (2019)
Trinuclear copper–pyrazolate entities are present in various Cu-based enzymes and nanojar supra­molecular arrangements. The reaction of copper(II) chloride with pyrazole (pzH) and sodium benzoate (benzNa) assisted by ...

1,3-Bis{[(2,6-di­methyl­phen­yl)sulfan­yl]meth­yl}benzene 

Garita Salazar, Bruno; Pineda Cedeño, Leslie William (2019)
The structure of the title compound, C24H26S2, an example of a pincer ligand with an SCS-chelation motif, illustrates the steric effects of the methyl groups in the thio­phenyl rings at the 2- and 6-positions, forcing a ...

1-Nitro-4-(1-propyn-1-yl)benzene 

Campos Fernández, Cristian Saul; Pineda Cedeño, Leslie William; Cabezas Pizarro, Jorge A. (2019)
The title compound, C9H7NO2, was prepared by alkynylation of 4-iodo­nitro­benzene with 1,3-dili­thio­propyne in the presence of 1 equivalent of CuI and catalytic amounts of Pd(PPh3)2Cl2. The complete mol­ecule is generated ...
