Fundamental Material Parameters Governing the Performance of Polymer‐Based Triboelectric Touch Sensors

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 3, January 15, 2026.
Optimizing PVDF fiber morphology and microstructure boosts triboelectric response by an order of magnitude without the need for fillers. ABSTRACT The growing demand for self‐powered electronics, such as touch sensors and wearable devices, highlights the need for reliable and efficient triboelectric systems.

Recycling of Polymer Components From Waste Face Masks for Asphalt Modification: A Mini Review

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 2, January 10, 2026.
ABSTRACT The COVID‐19 pandemic greatly increased plastic waste through widespread personal protective equipment (PPE) use, creating a serious environmental challenge. Disposable face masks (FM), primarily composed of non‐biodegradable polypropylene, account for an estimated 86 million units discarded monthly, leading to significant environmental ...

Indirect Calorimetry

Journal of the American Dietetic Association, 1997
Indirect calorimetry can be a useful tool to define nutritional status, determine nutritional requirements, and assess response to nutritional interventions. Measurements of oxygen consumption and carbon dioxide production may be used to determine cardiac output and work of breathing, and estimate the components of minute ventilation.

7 Indirect calorimetry

Baillière's Clinical Endocrinology and Metabolism, 1987
Summary Indirect calorimery is a method which allows the non-invasive measurement of enery expenditure and substrate utilization in humans. The procedure is described and the main equations to calculate energy expenditure and substrate utilization are presented.

Indirect calorimetry in cardiac patients

International Journal of Clinical Monitoring and Computing, 1988
Nineteen patients following open heart surgery were studied for the influence of cardiac function on metabolism. Diminished cardiac index was associated with the following changes in metabolism: lowering of the energy expenditure, an increase in respiratory quotient and conversion from fat to carbohydrate metabolism.
