Variability in Observation-Based Onroad Emission Constraints from a Near-Road Environment

open access: yesAtmosphere, 2020
This study uses Las Vegas near-road measurements of carbon monoxide (CO) and nitrogen oxides (NOx) to test the consistency of onroad emission constraint methodologies. We derive commonly used CO to NOx ratios (∆CO:∆NOx) from cross-road gradients and from

Growth of Cu2ZnSnS4 Thin Films Using Moderate Annealing Temperature and Short Dwell Time

open access: yesCumhuriyet Science Journal, 2019
In this study CZTS thin films were fabricated bya two-stage process that sputter deposition of metallic Cu, Zn, and Sn on Mocoated glass substrates and annealing process at 500 °C using various shortdwell times (4, 8, and 12 min) using Rapid Thermal ...

A gated strategy stabilizes room‐temperature phosphorescence

open access: yesAggregate, 2023
Room‐temperature phosphorescence (RTP) of purely organic materials is easily quenched with unexpected purposes because the excited triplet state is extremely susceptible to external stimuli.

Nanodiamond‐Infused Microgels for pH‐Tunable Rheology, Lubrication, and UV Protection

open access: yesAdvanced Functional Materials, EarlyView.
Microgels consisting of swollen polyacrylic acid polymer networks, impregnated with nanodiamonds provide protection from ultraviolet (UV) radiation harmful to human health. Nanodiamonds enable UV blockage and control of the rheology (flow) and lubrication (skin‐feel) of these microgel‐skincare‐mimics.

Unveiling Phonon Contributions to Thermal Conductivity and the Applicability of the Wiedemann—Franz Law in Ruthenium and Tungsten Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Thermal transport in Ru and W thin films is studied using steady‐state thermoreflectance, ultrafast pump–probe spectroscopy, infrared‐visible spectroscopy, and computations. Significant Lorenz number deviations reveal strong phonon contributions, reaching 45% in Ru and 62% in W.

Rapid thermal processing of CuAISe2 [PDF]

open access: yes, 2009
CuAl thin film metallic precursors were selenised using a tube furnace or a rapid thermal processor (RTP). A comparison is made between the two processes for slightly Cu rich films and best crystallographic and elemental properties are obtained for films
