Notas sobre fetichismo, historia e incertidumbre: más allá de la crítica a la austeridad

Isegoría, 2014
Estamos en medio de una onda enorme de protestas, rechazos masivos y multitudinarios de las condiciones contemporáneas. El trabajo se pregunta qué significa decir NO en una sociedad que requiere de los pobres y miserables que subsidien el sistema ...

Structural Basis of the Membrane Association by the Conserved RocS Membrane‐Targeting Sequence in Streptococcus

Advanced Science, EarlyView.
Chromosome segregation in Streptococcus pneumoniae depends on RocS, a bitopic protein whose membrane‐anchoring mechanisms were unclear. Using NMR and AFM, this study reveals that the widely conserved RocS anchor binds to membranes via a conserved kink‐helix motif which inserts into lipid nanodomains.

Bandgap‐Dependent Doping of Semiconducting Carbon Nanotube Networks by Proton‐Coupled Electron Transfer for Stable Thermoelectrics

Advanced Electronic Materials, EarlyView.
Proton‐coupled electron transfer doping with benzoquinone is applied to p‐dope dense films of semiconducting single‐walled carbon nanotubes. The doping efficiency depends on the pH of the doping solution and the bandgap of the nanotubes. The highest conductivities and power factors are achieved for small‐bandgap nanotubes, remaining stable for over 120

Effect of Regiochemistry on Doping and Thermoelectric Properties of n‐Doped Fullerene Derivatives

Advanced Electronic Materials, EarlyView.
Three fullerene derivatives doubly substituted with diethylene glycol chains (PDEG‐2) is presented. The different regiochemistry significantly affects the crystallinity and consequently the dielectric properties, electronic transport, and doping efficiency. By striking a balance between compatibility with the molecular dopant N‐DMBI and crystallinity a

The Role of Certifications in Improving Household Food Security Among Peruvian Farmers

Agribusiness, EarlyView.
ABSTRACT Achieving global food security requires sustainable transformations in agri‐food systems. Voluntary Sustainability Standards (VSS) such as Organic and Fairtrade aim to internalize certain social and environmental costs while promoting more equitable value distribution, improved market access, and sustainable production practices.
