Ventilation effects on humidity measurements in thermometer screens [PDF]

open access: yes, 2012
Relative humidity (RH) measurements, as derived from wet-bulb and dry-bulb thermometers operated as a psychrometer within a thermometer screen, have limited accuracy because of natural ventilation variations.

Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

open access: yesAdvanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...

Há equivalência entre a temperatura da membrana timpânica e a temperatura retal em ovinos Santa Inês normotérmicos? Is there equivalence between the tympanic membrane temperature and the rectal temperature in normothermic Santa Ines sheep?

open access: yesCiência Rural, 2008
A utilização do termômetro de raios infravermelhos para a aferição da temperatura timpânica em animais tem se tornado uma alternativa prática na clínica veterinária. Em ovinos, a mensuração da temperatura timpânica não foi suficientemente comparada com a

Narrow Inhomogeneous Distribution and Charge State Stabilization of Lead‐Vacancy Centers in Diamond

open access: yesAdvanced Functional Materials, EarlyView.
Lead‐vacancy (PbV) centers in diamond are expected to be a building block of quantum network nodes owing to a large ground state splitting, which suppresses phonon interaction. In this study, multiple PbV centers with nearly identical photon frequencies and stable charge state are fabricated by high‐pressure and high‐temperature anneal up to 2300 °C ...

Infrared thermometer on the wall (iThermowall): An open source and 3-D print infrared thermometer for fever screening

open access: yesHardwareX, 2021
In this COVID-19 pandemic, a non-contact handheld infrared thermometer is frequently used for fever screening. However, the handheld thermometer performance depends on the operator and the distance to the forehead.

$\gamma$-Radiation of thermalized Quark-Gluon-Plasma [PDF]

open access: yes, 2002
Long time ago, photon production was proposed as a probe and a thermometer for Quark-Gluon Plasma (QGP). However, only recently has the complete $\alpha_s$ order photon spectrum been obtained.

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

open access: yesAdvanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Rescuing the Assertability of Measurement Reports [PDF]

open access: yes, 2019
It is wholly uncontroversial that measurements-or, more properly, propositions that are measurement reports-are often paradigmatically good cases of propositions that serve the function of evidence. In normal cases it is also obvious that stating such a

Effective Sliding Motions of Vibration‐Induced Emission Stoppers in Mechanically Interlocked Molecules as Artificial Muscle Tougheners and In Situ Molecular Shuttling Sensors for Self‐Healable Mechano‐Fluorescent Polyurethane Organogels

open access: yesAdvanced Functional Materials, EarlyView.
The self‐healable ratiometric mechano‐fluorescent polyurethane (PU) organogel is constructed by incorporating a minor amount (ca. 1.5 wt.%) of the unconventional daisy chain rotaxane (as an artificial molecular muscle toughener) with specific sliding motions and ratiometric emission behaviors into the PU skeleton, which reveals the progressed intrinsic
