Fabrication of ZnO/Cu2O heterojunctions in atmospheric conditions: Improved interface quality and solar cell performance
(Elsevier, 2015-04-01)Zn1−xMgxO/Cu2O heterojunctions were successfully fabricated in open-air at low temperatures via atmospheric atomic layer deposition of Zn1−xMgxO on thermally oxidized cuprous oxide. Solar cells employing these heterojunctions ... -
Facial expression discrimination varies with presentation time but not with fixation on features: A backward masking study using eye-tracking
(Taylor & Francis, 2014-01-02)The current study investigated the effects of presentation time and fixation to expression-specific diagnostic features on emotion discrimination performance, in a backward masking task. While no differences were found ... -
A facile and fully automated on-fiber derivatization protocol for direct analysis of short-chain aliphatic amines using a matrix compatible solid-phase microextraction coating
(Elsevier, 2017-07-29)Solid-phase microextraction (SPME) analysis of short-chain aliphatic amines (C-3-C-6) in aqueous solutions was investigated using pentafluorobenzaldehyde (PFBAY) as on-fiber derivatization reagent. A standard gas generating ... -
Facile solid-state synthesis of eco-friendly sodium iron silicate with exceptional sodium storage behaviour
(Elsevier, 2018-09-01)It is crucial to develop stable energy sources for rechargeable sodium-ion batteries using simple synthesis methods. Herein, we report a facile route for synthesizing phase-pure carbon-coated Na2FeSiO4 polyanionic cathodes ... -
Factors associated with study completion in patients with premature acute coronary syndrome
(Public Library of Science, 2017-03-16)Background Factors associated with study completion in younger adults are not well understood. This study sought to describe psychosocial, clinical, and demographic features associated with completion of a study of men and ... -
Factors of Haptic Experience across Multiple Haptic Modalities
(Association for Computing Machinery, 2023-04-19)Haptic Experience (HX) is a proposed set of quality criteria useful to haptics, with prior evidence for a 5-factor model with vibrotactile feedback. We report on an ongoing process of scale development to measure HX, and ... -
Factors of Influence on the Performance of a Short-Latency Non-Invasive Brain Switch: Evidence in Healthy Individuals and Implication for Motor Function Rehabilitation
(Frontiers Media, 2016-01-21)Brain computer interfacing (BCI) has recently been applied as a rehabilitation approach for patients with motor disorders, such as stroke. In these closed-loop applications, a brain switch detects the motor intention from ... -
Failure parameter identification and validation for a dual-phase 780 steel sheet
(Elsevier, 2017-10-01)A hybrid experimental-numerical procedure was implemented to determine the failure surface of a dual-phase 780 steel sheet as a function of the effective plastic strain, triaxiality, and Lode parameter using butterfly ... -
Failure time studies with intermittent observation and losses to follow-up
(Wiley, 2020-12-01)In health research interest often lies in modeling a failure time process but in many cohort studies failure status is only determined at scheduled assessment times. While the assessment times may be fixed upon study entry, ... -
Far-field interference of a neutron white beam and the applications to noninvasive phase-contrast imaging
(American Physical Society, 2017-04-26)The phenomenon of interference plays a crucial role in the field of precision measurement science. Waveparticle duality has expanded the well-known interference effects of electromagnetic waves to massive particles. The ... -
