Unveiling the Neutral Forms of Glutamine

Author: Iker León, Elena R. Alonso, Santiago Mata, Carlos Cabezas, Prof. Jose Luis Alonso

Angewandte (2019)

Abstract:
Neutral glutamine has been evaporated by laser ablation of its solid sample to seed a rare gas carrier prior to a supersonic expansion and proved by Fourier transform microwave techniques. We report on three distinct neutral conformers that show a….

Abstract:
We describe the reversible intercalation of Na under graphene on Ir(1 1 1) by photo-dissociation of a previously adsorbed NaCl overlayer. After room temperature evaporation, NaCl adsorbs on top of graphene forming a bilayer. With a combination of electron diffraction and photoemission….

Neaton & Alexander Weber-Bargioni 

Nature Communications volume 10, Article number: 3382 (2019

Abstract:
Chalcogen vacancies are generally considered to be the most common point defects in transition metal dichalcogenide (TMD) semiconductors because of their low formation energy in vacuum and their frequent observation in transmission electron microscopy studies. Consequently….

Abstract:
We report an extensive structural characterization of the surface of 1T-PtTe2 crystals by means of helium atom scattering (HAS) and ultra-high resolution scanning tunnelling microscopy (STM). HAS reveals that this bi-dimensional surface presents a large structural corrugation….

Nanoarquitecturas de grafeno con precisión atómica

Author: Cesar Moreno Sierra, Ara García-Lekue, Aitor Mugarza
Revista Española de Física. Vol 33, No 4 (2019)

Abstract:
La síntesis de arquitecturas covalentes en superficie y con precisión atómica se ha erigido como uno de los métodos más prometedores para dotar de nuevas funcionalidades al grafeno, un material ya de por si superlativo en múltiples aspectos….
