Engineering the Metal/Oxide Interfacial O‐Filling Effect to Tailor Oxygen Spillover for Efficient Acidic Water Oxidation

Advanced Functional Materials, EarlyView.
The oxygen spillover from Ir to the oxide support with interfacial oxygen vacancies during OER is revealed. These interfacial oxygen vacancies as an oxygen transport zone not only regulate the in situ Ir catalytic structure toward boosted activity but also suppress Ir over‐oxidation via directional OH‐filling effects, thereby ensuring overall high ...

Electronic Structure and Properties of SrAlGe and BaAlGe [PDF]

arXiv, 2012
The electronic structures of BaAlGe and SrAlGe which are superconductors with hexagonal honeycomb layers have been studied by using a first principles method. Energy bands, Fermi surafces, and density of states are presented. The two materials have topologically different Fermi surfaces.

Holographic Fermi arcs and a d-wave gap

, 2010
We study fermion correlators in a holographic superfluid with a d-wave (spin two) order parameter. We find that, with a suitable bulk Majorana coupling, the Fermi surface is anisotropically gapped. At low temperatures the gap shrinks to four nodal points.

Ultra‐Effective Light‐Activated Antibacterial Activity via Carboxyl Functionalized Graphene Quantum Dots and Films

Advanced Functional Materials, EarlyView.
Carboxyl‐functionalized graphene quantum dots (cGQDs) exhibit high singlet oxygen quantum yield due to strong spin–orbit coupling. cGQDs achieve minimum bactericidal concentration of only 0.4 µg mL−1 against S. aureus under low‐intensity illumination.

Elucidating Sodium Ion Storage Mechanisms in Hard Carbon Anodes at the Electronic Level

Advanced Functional Materials, EarlyView.
High‐resolution, multi‐frequency continuous wave, and pulsed Electron Paramagnetic Resonance (EPR) spectroscopy uncover the intricate Na ion storage mechanisms in hard carbon. This study reveals the coexistence of Na ion intercalation and solvent co‐intercalation, alongside a subsequent transition of Na ions from ionic to quasi‐metallic to metallic ...

Tin‐Based 2D/3D Perovskite Vertical Heterojunction for High‐Performance Synaptic Phototransistors

Advanced Functional Materials, EarlyView.
Phototransistors based on tin‐based 2D/3D perovskite heterostructures show an ultrahigh responsivity and detectivity at a low gate voltage across a broad wavelength region from ultraviolet to near‐infrared. The devices can replicate neuromorphic learning and remembering behaviors to light stimuli, in addition to electric depression and memory erasure ...

Probing the holographic Fermi arc with scalar field: numerical and analytical study

Journal of High Energy Physics, 2019
Fermi arcs are disconnected contour of Fermi surface, which can be observed in pseudo-gap phase of high temperature superconductors. Aiming to understand this pseudo-gap phenomena, we study a holographic Fermionic system coupled with a massive scalar ...
