Unruh Effect and the Concept of Temperature

open access: yes, 2013
Based on a discussion of the concepts of temperature, passivity and efficiency in the framework of quantum field theory, the physical interpretation of the Unruh effect is reviewed PACS: 03.70.+k, 04.70.DyComment: v2: 11 pages, no figures; references and

Scalable Polyelectrolyte Complex‐Based Sorbent With Hourly Sorption−Desorption Cycles for Multicyclic Atmospheric Water Harvesting in Arid Environments

open access: yesAdvanced Functional Materials, EarlyView.
A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

open access: yesAdvanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

No Reliable Studies of Climate Change Without Henry’s Law and A New Thermometer for The Global Temperature

open access: yesJournal of Marine Science Research and Oceanography
In our previous paper “No experimental evidence for the significant anthropogenic climate change” we had a reference to this paper. Thus, we have presented a new theory: how Henry’s Law regulates the concentration of CO2 in the atmosphere. This theory uses a physically perfect unit impulse response to convolve signals.

Bridging thermodynamics and metrology in non-equilibrium Quantum Thermometry [PDF]

open access: yes, 2018
Single-qubit thermometry presents the simplest tool to measure the temperature of thermal baths with reduced invasivity. At thermal equilibrium, the temperature uncertainty is linked to the heat capacity of the qubit, however the best precision is ...

The relationship between COPD Assessment Test (CAT) scores and Distress Thermometer (DT) results in COPD patients.

open access: yesAnnals of Agricultural and Environmental Medicine, 2019
INTRODUCTION Chronic Obstructive Pulmonary Disease (COPD) is a condition that affects over 2 million adults in Poland. In recent years, increasing attention has been focused on improving the quality of life of patients with COPD, which includes ...

From Bug to Feature: Harnessing Cross‐Sensitivity for Multiparametric Luminescence Sensing

open access: yesAdvanced Functional Materials, EarlyView.
Cross‐sensitivity in luminescence sensing is reframed from a limitation into a resource for multiparametric detection. Using ruby microspheres as a model system, cross‐sensitivity is quantitatively assessed and exploited through linear discriminant analysis, enabling simultaneous, correction‐free pressure and temperature sensing with a single ...
