Establishing a heterostructure is one of the adequate strategies for enhancing device performance and has been explored in sensing, and energy applications. In this study, we constructed a heterostructure through a two-step process involving hydrothermal synthesis of CuO nanostructures and subsequent spin coating on MBE-grown InGaN NRs. We found that the CuO content on the InGaN NRs has a great impact on carrier injection at the heterojunction and thus the HS gas sensing performance.

The clinical significance of volatile organic compounds (VOC) in detecting diseases has been established over the past decades. Gas chromatography (GC) devices enable the measurement of these VOCs. Chromatographic peak alignment is one of the important yet challenging steps in analyzing chromatogram signals.

- Early diagnosis of skin barrier dysfunction is crucial for preventing conditions like atopic dermatitis and psoriasis, with transepidermal water loss (TEWL) being a key measurement method.
- Existing TEWL devices face limitations such as environmental sensitivity, bulkiness, and high costs, hindering their effectiveness for routine use.
- The newly developed Wearable Analytical Skin Probe (WASP) offers a noninvasive and accurate solution for continuous monitoring of skin water vapor flux, distinguishing between different types of sweating and proving effective in practical applications.
Importance: Breath analysis has been explored as a noninvasive means to detect COVID-19. However, the impact of emerging variants of SARS-CoV-2, such as Omicron, on the exhaled breath profile and diagnostic accuracy of breath analysis is unknown.
Objective: To evaluate the diagnostic accuracies of breath analysis on detecting patients with COVID-19 when the SARS-CoV-2 Delta and Omicron variants were most prevalent.
