Smart Face Masks as Wearable Respiratory Sensors: A Review of Sensor Technologies, Materials, and Future Directions

Advanced Healthcare Materials, EarlyView.
This review highlights recent advances in smart face masks that actively monitor breathing. By integrating humidity, gas, temperature, pressure, strain, and triboelectric sensors, these masks track key respiratory parameters in real time. The article summarizes sensor mechanisms, compares performance across studies, and discusses challenges and future ...

Fluctuation phenomena in crystal plasticity - a continuum model [PDF]

, 2005
On microscopic and mesoscopic scales, plastic flow of crystals is characterized by large intrinsic fluctuations. Deformation by crystallographic slip occurs in a sequence of intermittent bursts ('slip avalanches') with power-law size distribution. In the

The physical oceanography of the transport of floating marine debris [PDF]

, 2020
Marine plastic debris floating on the ocean surface is a major environmental problem. However, its distribution in the ocean is poorly mapped, and most of the plastic waste estimated to have entered the ocean from land is unaccounted for.

Microplastics and their environmental effects

Environmental Toxicology and Pharmacology, 2023
Microplastics (MPs) are acknowledged as emerging contaminants that pose a substantial threat to the environment. The adverse impacts of MP pollution extend across marine, freshwater, and terrestrial ecosystems, covering regions from the Tropics to the Poles. Although our comprehension of MP behavior has progressed in recent years, it is still difficult

Respiratory Organ‐on‐a‐Chip for Disease Modeling: From Architecture to Functional Integration

Advanced Healthcare Materials, EarlyView.
Respiratory organ‐on‐a‐chip (ROC) models capture key mechanical and cellular cues of the human respiratory system, enabling quantitative dissection of disease mechanisms. This review links ROC architectures to disease modeling, functional integration, and commercialization, and proposes a decision framework that aligns model complexity with mechanistic

First Evidence of Potential Microplastic Ingestion of Yellow Striped Goat Fish Upeneus vitattus (Forsskal, 1775) Caught in Malita, Davao Occidental, Philippines

Ilmu Kelautan
Microplastic (MP) study in the Philippines is gaining attention because of the recent trends in macro-microplastic study worldwide and there is already a call for research to help the degrading marine environment in the country. No study in Malita, Davao

Unveiling hidden contaminants: a systematic quantification and characterization of microplastics in hemodialysis and peritoneal dialysis fluids

BMC Nephrology
Microplastics (MPs) are an emerging environmental and biomedical concern due to their potential bioaccumulation and toxic effects. Given the extensive exposure of dialysis patients to large volumes of dialysate and water, the presence of MPs in dialysis ...

Microplastic incorporation into soil in agroecosystems [PDF]

, 2017
Background: We live in a plastic age (Thompson et al., 2009), with microplastic (typically defined as plastic particles < 5 mm) becoming an increasingly appreciated aspect of environmental pollution. Research has been overwhelmingly focused on aquatic
