Enhanced Light Extraction Efficiency by Self-Masking Technology with Carbonized Photoresist for Light-Emitting Diodes

open access: yesMicromachines, 2023
This work investigates a self-masking technology for roughening the surface of light-emitting diodes (LEDs). The carbonized photoresist with a naturally nano/micro-textured rough surface was used as a mask layer. After growing the Si3N4 passivation layer

Comparison of the performance of a microwave plasma torch and a gliding arc plasma for hydrogen production via methane pyrolysis

open access: yesPlasma Processes and Polymers, Volume 20, Issue 1, January 2023., 2023
Hydrogen production via plasma methane pyrolysis is investigated using a microwave plasma torch (MPT) and a gliding arc plasmatron (GAP). The performance of the two plasma sources in terms of methane conversion, product spectrum, and energy efficiency is compared. The physical and chemical properties of the produced carbon particles are compared.

Evaluation of machine learning methods for covariate data imputation in pharmacometrics

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 11, Issue 12, Page 1638-1648, December 2022., 2022
Abstract Missing data create challenges in clinical research because they lead to loss of statistical power and potentially to biased results. Missing covariate data must be handled with suitable approaches to prepare datasets for pharmacometric analyses, such as population pharmacokinetic and pharmacodynamic analyses.

Where have all the ions gone, long time passing? Tandem quadrupole mass spectrometers with atmospheric pressure ionization sensitivity gains since the mid‐1970s. A perspective

open access: yesRapid Communications in Mass Spectrometry, EarlyView., 2022
The gains in sensitivity since 1975 for quadrupole mass spectrometers equipped with atmospheric pressure ionization (API), and in particular triple quadrupole mass spectrometers (QqQs) since 1981, have been driven by the needs of the environmental, biomedical, agricultural, and other scientific research, industrial, regulatory, legal, and sporting ...
