FACTORES QUE INCIDEN EN EL DESARROLLO AGRO INDUSTRIAL DE EL SALVADOR
La Universidad, 2018 El presente estudio plantea el siguiente problema·¿En qué medida la falta de financiamiento estatal condiciona el incremento de cultivos no tradicionales y por ende el desarrollo agroindustrial?; se enmarca en el contexto socioeconómico de El Salvador y

Advanced Materials, EarlyView.Magnetic doping of the topological insulator Bi2Te3 with erbium adatoms induces out‐of‐plane magnetism and breaks time‐reversal symmetry, opening a Dirac gap and driving a Fermi surface transition from hexagonal to star‐of‐David geometry. Microscopy, spectroscopy, and magnetic dichroism reveal atomically controlled magnetic interactions that tailor the

Posición de AGEUS ante las elecciones del 20 de Marzo
La Universidad, 2018 Nuevamente en esta campaña electoral, surgen los politiqueros demagogos, corruptos y vende-patria, que solamente en momentos como éste se acercan al pueblo para pedirle el voto y a prometerle resolver sus problemas Luego que logran su objetivo (llegar a

Advanced Materials, EarlyView.Bioorthogonal chemistry was applied to intracellularly photoactivate Doxorubicin (Dox) using gold nanostars (AuNSt) and near‐infrared (NIR) light. Two prodrugs were used: one photoactivatable, masked with 2‐nitrobenzyl carbamate (proDox1) and another photolabile, masked with 2‐nitrobenzyl diol (proDox2), which was attached to the AuNSt surface.

Resolving the Structural Duality of Graphene Grain Boundaries
Advanced Materials, EarlyView.Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.
