Fabricación de estructuras bidimensionales para dispositivos electrónicos moleculares

, 2020
Es necesario que la metodología utilizada para abordar el desarrollo de tecnologías en la industria electrónica sufra una revolución en los próximos años. Hasta el momento ha consistido en seleccionar materiales que posean características electrónicas adecuadas y reducir el tamaño de los dispositivos a lo largo del tiempo.

Aplicando la Regla del Octeto en la Estructura Molecular

Vida Científica Boletín Científico de la Escuela Preparatoria No. 4
La regla del octeto propuesta por Gilbert Lewis en 1917 como la regla del ocho, es una herramienta útil para representar las estructuras de más baja energía de moléculas covalentes. Para los estudiantes de química, es indispensable que conozcan cómo surge y que reconozcan, sus alcances y limitaciones porque les ayuda a realizar la representación ...

Modulation of SAL retrograde signalling promotes yield and water productivity responses in dynamic field environments

New Phytologist, Volume 249, Issue 3, Page 1219-1233, February 2026.
Summary Chloroplast‐to‐nucleus retrograde signalling enables rapid stress responses in plants, but whether these signals accumulate to affect crop performance across entire growing seasons under field conditions remains unknown. We generated wheat mutants with targeted deletions in specific SAL gene copies from two distinct homeologous groups (TaSAL1 ...

Ab Initio studies of the atomic structure and electronic density of states of pure and hydrogenated a-Si

, 2000
We propose a method to simulate a-Si and a-Si:H using an ab initio approach based on the Harris functional and thermally amorphisized periodically continued cells with at least 64 atoms, and calculate their radial distribution functions.

Molecular–physiological model integration revolutionizes cereal flowering prediction

New Phytologist, Volume 249, Issue 3, Page 1373-1388, February 2026.
Summary Rapid prediction and control of flowering time is essential for breeding crops resilient to changing climates. Current models often fail to predict flowering time in new cultivars because molecular models lack integration of environmental signals, while physiological models inadequately capture the interactions of vernalization, photoperiod and

Evolution of molecular communication in the permanent Azolla symbiosis

New Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Transcriptional outputs and condensates – formation and function

New Phytologist, Volume 249, Issue 3, Page 1145-1154, February 2026.
Summary The dynamic spatiotemporal organization of macromolecules is key to the proper function of the cell, allowing the exquisite regulation of diverse processes from gene expression to enzymatic function. The formation of biomolecular condensates via phase separation (PS) acts as a general mechanism for selectively concentrating proteins, nucleic ...

Future heatwave conditions inhibit CO2‐induced stomatal closure in wheat

New Phytologist, Volume 249, Issue 3, Page 1234-1252, February 2026.
Summary As global temperatures and the severity of droughts continue to increase, food crops will more frequently experience high vapour pressure deficit (VPD) during heatwave events. However, the interactive effects of rising atmospheric CO2 and high‐VPD heatwaves on crop water fluxes and yields are currently unknown.
