Low ambient temperature and hospitalization for cardiorespiratory diseases in Brazil [PDF]

open access: yes, 2023
Studies have shown that larger temperature-related health impacts may be associated with cold rather than with hot temperatures. Although it remains unclear the cold-related health burden in warmer regions, in particular at the national level in Brazil ...

Low ambient temperature correlates with the severity of dry eye symptoms

open access: yesTaiwan Journal of Ophthalmology, 2022
PURPOSE: The symptoms of dry eye disease (DED) are influenced by environmental factors, but the effect of ambient temperature is less certain. Our purpose was to investigate the relationship between the severity of DED symptoms and the ambient ...

Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition

open access: yesAdvanced Engineering Materials, EarlyView.
A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

open access: yesAdvanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Synthesis of ZSM-2 nanocrystals at ambient temperature

open access: yes, 2014
ZSM-2 nanorods with crystal size around 50 nm were successfully synthesized at ambient temperature (30 degrees C). The crystallization process of ZSM-2 zeolite under ambient temperature was studied and discussed according to the measurement of ...
