Sub‐Terahertz Memristor Switches Using MoS2 by Liquid–Liquid Interface Assembly

open access: yesAdvanced Science, EarlyView.
This work introduces application‐ready sub‐terahertz memristor switches fabricated from electrochemically exfoliated MoS2 nanosheets assembled at a liquid–liquid interface. The devices exhibit robust unipolar resistive switching, low insertion loss, and high isolation across 10–110 GHz.

Dynamic Reconstruction‐Engineered Heterointerfaces for Acidic Hydrogen Evolution at Ampere‐Level Current Density

open access: yesAdvanced Science, EarlyView.
A dynamic reconstruction strategy was utilized to construct PtCu/Cu3P heterostructures on the surface of self‐supporting Cu3P nanowires. The loose porosity in the restructured layer, together with a dynamic “dissolution‐redeposition” equilibrium during electrocatalysis, enables the electrode to maintain a low, stable overpotential for 240 h at ampere ...

¿Universidad docente o Universidad investigadora?

open access: yesREVISTA CIENTÍFICA (INSTITUTO DE INVESTIGACIONES QUÍMICAS Y BIOLÓGICAS. FACULTAD DE CIENCIAS QUÍMICAS Y FARMACIA. UNIVERSIDAD DE SAN CARLOS DE GUATEMALA.
Este artículo presenta un panorama sobre el tema de la investigación en la universidad. Pues hay que hacer notar que a pesar de existir una política institucional y ser uno de los ejes de la educación superior, hasta ahora la investigación no es el eje fundamental de las actividades del docente universitario.

Electrolyte–Framework Matching in High‐Voltage TEMPO‐COF Cathodes for Lithium Batteries

open access: yesAdvanced Science, EarlyView.
TEMPO‐functionalized covalent organic frameworks are investigated as high‐voltage cathodes for lithium batteries. Screening five electrolyte anions identifies lithium difluoro(oxalato)borate (LiDFOB) as the optimal electrolyte, balancing capacity, rate capability, and cycling stability, while buckypaper electrodes achieve high mass loading (40 mg cm−2)

La universidad nacional experimental: de una universidad especializada a una universidad investigadora.

open access: yesIntegración y Conocimiento, 2015
En este artículo, se analizará el comportamiento de las Universidades Nacionales Experimentales (UNE) y su relación con la participación en la política científica actual. También se intentará definirlas, caracterizarlas e impulsarlas hacía el desafío de investigar y desarrollar nuevos conocimientos.

Exact Discrete Stochastic Simulation With Deep‐Learning‐Scale Gradient Optimization

open access: yesAdvanced Science, EarlyView.
A 203,796‐parameter gene regulatory network classifies handwritten digits with 98.4% accuracy using exact stochastic dynamics. The framework decouples forward simulation from backward differentiation, making continuous‐time Markov chain models compatible with deep‐learning optimization.

La universidad, realidad problemática

open access: yesRevista EDUCA UMCH, 2016
The University of San Marcos de Lima asks me for a few words about “The University in the 20th century”. The occasion, its fourth centenary. The reason, the awareness that all the clear heads that move around the University have, that this is nothing simple and obvious today, that it can march without more and do the same as until now.

Artificial Host‐Guest Recognition Directs Glycometabolically Engineered Macrophages to Tumors

open access: yesAdvanced Science, EarlyView.
Glycoengineered supramolecular macrophages (GSAR‐M) are developed using glycometabolic labeling for bioorthogonal host‐guest tumor targeting. This engineering approach unexpectedly enhances macrophage migration, phagocytosis, and pseudopodia formation. Consequently, GSAR‐M demonstrate robust tumor‐targeting specificity, effectively arrest tumor growth,
