Unveiling the Fundamental Principles of Reconfigurable Resistance States in Silver/Poly(Ethylene Glycol) Nanofluids

open access: yesAdvanced Science, EarlyView.
The electrophoretic reorganization of Ag nanoparticles within a poly(ethylene glycol) leads to the formation of conductive bridges with reconfigurable resistance states. Diverse conduction characteristics of the bridge range between ohmic conduction, nonlinear tunneling, or space charge‐limited conduction, and high resistance states.

Exo‐Selective Intramolecular (4+3) Cycloadditions to Trans‐Fused Perhydroazulenes: An Asymmetric Formal Synthesis of (−)‐Pseudolaric Acid B

open access: yesAngewandte Chemie, EarlyView.
We present an asymmetric formal synthesis of pseudolaric acid B, for which we developed a new family of substrates with an epoxide geminally tethered to a sidechain bearing a furan, which undergoes a TESOTf‐catalyzed intramolecular (4+3) cycloaddition to yield the trans‐fused perhydroazulene core and the requisite quaternary stereocenter of the natural

Three-dimensional connectivity during summer in the northern Gulf of California

open access: yesScientia Marina, 2016
Connectivity studies in the Gulf of California are an important tool for improving the use and management of the gulf’s natural resources. The goal of this work was to study the three-dimensional connectivity in the northern Gulf of California during two

New array monitors seismic activity near the Gulf of California in Mexico [PDF]

open access: yes, 2003
The Gulf of California rift forms a geologically young and active plate boundary that links the San Andreas strike‐slip fault system in California to the oceanic spreading system of the East Pacific Rise.

Unlocking the Interaction Mechanism of CNTs and C‐S‐H on Enhancing Elastic and Viscoelastic Properties of Alite Paste

open access: yesAdvanced Science, EarlyView.
This study explores carbon nanotubes’ (CNTs) role in enhancing alite paste’ elasticity and viscoelasticity. Experimental and simulation results reveal that CNTs weakly influence nucleation but significantly refine C‐S‐H gel structure and calcium hydroxide distribution.

Catalytic 1,2‐Migratory Insertion in a Bismuth Redox Platform: Reductive Arylation of Aldehydes

open access: yesAngewandte Chemie, EarlyView.
We report a multicomponent reaction involving an aryl halide, an aldehyde, and a silane derivative, facilitated by low‐valent bismuth redox catalysis under mild conditions. The protocol represents an unprecedented example of four elementary organometallic steps at a Bi center within the catalytic cycle.

On two Psolidae (Echinodermata: Holothuroidea) from the Gulf of California, Mexico Dos Psolidae (Echinodermata: Holothuroidea) del golfo de California, México

open access: yesRevista Mexicana de Biodiversidad, 2013
Two species of holothuroids of the family Psolidae have been collected in the Gulf of California, Mexico. Psolus diomedeae Ludwig, 1894, a species previously known from the Pacific coast of Mexico and abundant in the Gulf of California was collected in 3

Diet of California sea lions, Zalophus californianus, at San Jorge Island, northern Gulf of California, Mexico, 1998–1999

open access: yesCiencias Marinas, 2005
The California sea lion, Zalophus californianus (Lesson, 1828), is the only resident pinniped in the Gulf of California, the largest populations inhabiting the Midriff islands and the northern gulf. San Jorge Island, in the northern gulf, has the second

ROV's Video Recordings as a Tool to Estimate Variation in Megabenthic Epifauna Diversity and Community Composition in the Guaymas Basin [PDF]

open access: yes, 2020
Patterns in benthic megafauna diversity in littoral and intertidal zones in the Gulf of California have been associated with both habitat heterogeneity and substrate type.

Variation in styles of rifting in the Gulf of California [PDF]

open access: yesNature, 2007
Constraints on the structure of rifted continental margins and the magmatism resulting from such rifting can help refine our understanding of the strength of the lithosphere, the state of the underlying mantle and the transition from rifting to seafloor spreading. An important structural classification of rifts is by width, with narrow rifts thought to
