Micropatterned Biphasic Printed Electrodes for High‐Fidelity on‐Skin Bioelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Micropatterned biphasic printed electrodes achieve unprecedented skin conformity and low impedance by combining liquid‐metal droplets with microstructured 3D lattices. This scalable approach enables high‐fidelity detection of ECG, EMG, and EEG signals, including alpha rhythms from the forehead, with long‐term comfort and stability.

Evaluation of Machine Learning Approaches for Hydration Heat Prediction in Energy-Efficient Cement Composites

open access: yesEnergies
Accurate prediction of the heat of hydration is essential for designing low-emission, durable mortars and concretes with controlled thermal behavior, as the partial replacement of Portland cement clinker with supplementary cementitious materials (SCMs ...

Studies about the heat of hydration developed in mortars with natural and by-product materials

open access: yesMateriales de Construccion, 2000
The heat of hydration developed in reactions of mortars and concretes can be sensibly reduced using pozzolanic materials. However, the decrease of the heat of hydration is not directly proportional to the amount of cement substituted, because of the heat

Heat Shield Hydrate

open access: yesInternational Journal of Advanced Research in Science, Communication and Technology
In recent years, increasing global temperatures and heatwave occurrences have heightened the risk of heat-related illnesses such as dehydration and heatstroke. To address this, 'Heat Shield Hydrate' is an Android-based smart application designed to promote personal hydration awareness and heat safety management.

Biodegradable and Recyclable Luminescent Mixed‐Matrix‐Membranes, Hydrogels, and Cryogels based on Nanoscale Metal‐Organic Frameworks and Biopolymers

open access: yesAdvanced Functional Materials, EarlyView.
The study presents biodegradable and recyclable mixed‐matrix membranes (MMMs), hydrogels, and cryogels using luminescent nanoscale metal‐organic frameworks (nMOFs) and biopolymers. These bio‐nMOF‐MMMs combine europium‐based nMOFs as probes for the status of the materials with the biopolymers agar and gelatine and present alternatives to conventional ...

Hypohydration and Mood State in Free-Living Males and Females [PDF]

open access: yes, 2015
Previous research has shown that acute dehydration can result in changes in mood. These changes have been reported in less than a 1% loss in total body water. However, the effect of hypohydration (i.e., reflected through high urine concentration) on mood

An Occupational Heat Stress and Hydration Assessment of Agricultural Workers in North Mexico

open access: yesInternational Journal of Environmental Research and Public Health, 2020
Expanding agribusiness in Northern Mexico has increased demand for workers from Southern Mexico, with hundreds of thousands migrating for work annually. Extreme temperatures, physical labor, and low fluid consumption place workers at risk for heat strain

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

The Effects of Mild Dehydration on Cycling Performance in the Heat [PDF]

open access: yes, 2018
Introduction: Hypohydration exceeding 2% of body mass (bm), affected by heat and thirst level, leads to decreased athletic performance. Both physiological and psychological factors of dehydration have an impact on an athlete’s perceived performance ...

Model for the hydration of non-polar compounds and polymers

open access: yes, 2002
We introduce an exactly solvable statistical-mechanical model of the hydration of non-polar compounds, based on grouping water molecules in clusters where hydrogen bonds and isotropic interactions occur; interactions between clusters are neglected ...
