Topographic compensation in auger electron spectroscopy.

open access: yesHyomen Kagaku, 1987
Abstract The scanning Auger microprobe (SAM) produces Auger images which provide information on the elemental distribution of specimen surfaces. However specimen topography affects the data obtained. To eliminate the topographical effect, the peak‐to‐background ratio, ( P −

Selenium‐Based Nanoplatforms: An Emerging Theranostic Paradigm for Gynecological Cancers

open access: yesAdvanced Science, EarlyView.
This reivew summarizes Selenium as a multifunctional anticancer regulator in gynecological cancers. It reduces tumor risk, enhances therapeutic efficacy, and reduces treatment toxicity. Selenium also overcomes chemoraditherapy resistance, improving overall treatment outcomes. ABSTRACT Gynecological cancers present significant therapeutic challenges due

Interactive Strength between C60 Thin Film and Si(001) and Its Influence on Nano-Scaled Tribology

open access: yesTribology Online, 2008
The influences of interactions between C60 thin films and Si substrates were investigated using atomic force microscopy (AFM). It was found that higher friction coefficient was obtained at the C60 domains formed on the H-terminated Si(001) substrate and ...

A measurement of the evolution of Interatomic Coulombic Decay in the time domain

open access: yes, 2013
During the last 15 years a novel decay mechanism of excited atoms has been discovered and investigated. This so called ''Interatomic Coulombic Decay'' (ICD) involves the chemical environment of the electronically excited atom: the excitation energy is ...

Suppressed Auger Heating of Hot Carriers in Cu‐Doped Colloidal Quantum Wells

open access: yesAdvanced Science, EarlyView.
ABSTRACT Auger heating represents a major bottleneck for hot carrier (HC) relaxation in colloidal quantum wells (CQWs), delaying carrier accumulation in band‐edge states and diminishing performance in light‐emitting applications. To address this issue, we introduce copper doping in CdSe CQWs to create midgap states, which efficiently suppresses Auger ...

Positron annihilation induced Auger electron spectroscopy [PDF]

open access: yes
Recently, Weiss et al. have demonstrated that it is possible to excite Auger transitions by annihilating core electrons using a low energy (less than 30eV) beam of positrons.

Unity Quantum Yield of High‐Entropy Quantum Dots Composited With Photonic Crystals for Information Encryption

open access: yesAdvanced Science, EarlyView.
This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.

V2CTx MXene as a Sacrificial Promoter for NiFe Catalyst for Anion Exchange Membrane Electrolyzers

open access: yesAdvanced Science, EarlyView.
These findings demonstrate that V2CTx functions beyond passive conductive support as an active electronic participant whose structural legacy sustains durable performance even after vanadium leaching in Anion Exchange Membrane (AEM) Electrolysers. ABSTRACT Nickel‐iron layered double hydroxides (NiFe‐LDH) show excellent activity, their poor conductivity

Platinum Particles Embedded into Nanowires of Polyaniline Doped With Poly(Acrylic Acid-co-Maleic Acid) as Electrocatalyst for Methanol Oxidation

open access: yesInternational Journal of Electrochemical Science, 2011
Polyaniline-poly(acrylic acid-co-maleic acid) (PANI-PAMA) with a nanowire network structure is prepared using a doping-dedoping-redoping route. Platinum (Pt) particles are deposited into PANI and PANI-PAMA nanowire network structures via a potentiostatic
