Water–air carbon fluxes in the coastal upwelling zone off northern Baja California
Ciencias Marinas, 2015 An important challenge in marine science is to quantify the air–sea flux of carbon because of its possible relation to climate change and the decreasing pH in seawater.

Primary productivity observations in the eastern tropical Pacific off Cabo Corrientes, Mexico
Ciencias Marinas, 2009 The in situ primary productivity (PP) and phytoplankton biomass (chlorophyll a concentration, Chla) of the Cabo Corrientes region, in the eastern tropical Pacific off Mexico, were studied using data from three oceanographic cruises (May and November ...

Microzooplankton grazing impact on the phytoplankton community at a coastal upwelling
Ciencias Marinas, 2017 Experiments were carried out at a coastal upwelling site (ENSENADA station) off northern Baja California (México) during autumn 2015 (OCT-15) and spring 2016 (APR-16) to estimate phytoplankton daily growth (µo) and mortality (m) rates and to assess ...

Ciencias Marinas, 2018 We characterized the spatial and temporal variations of sea surface temperature (SST), satellite-derived chlorophyll a (Chlsat) con-centration, and phytoplankton production (PP) along two 300-km long transects in the southernmost part of the California ...

In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Moiré Folded Helical States at the Interfaces of Heterostructures
Advanced Physics Research, EarlyView.This manuscript explores a minimal ladder model of a graphene‐topological‐insulator heterostructure where moiré superlattices modulate Rashba spin‐orbit coupling. The study reveals that SOC lifs spin degeneracy, halves spectral periodicity, and induces “helicity fragmentation” across moiré minibands.
