Microfluidic systems are widely used in biology for their ability to control environmental parameters. Specifically, cell culture or chemistry in microfluidic devices requires tight control of the temperature. In addition, microfluidic devices can be made transparent to visible light and compatible with inverted…

'Nutan Patil' 'Micah J. Green'] Carbon nanomaterials have been shown to rapidly evolve heat in response to electromagnetic fields. Initial studies focused on the use of microwaves, but more recently, it was discovered that carbon nanomaterial systems heat in response to electric fields in the radio frequency range (RF…

Plasmonic heating has been utilized in many applications, including photocatalysis, photothermal therapy, and photocuring. However, the heat dissipation process of the plasmonic nanoparticles (NPs) and the surrounding matrix is complex. How high the temperature of the matrix that surrounds the plasmonic NPs, such as…

With the ability to convert external excitation into heat, nanomaterials play an essential role in many biomedical applications. Two modes of nanoparticle (NP) array heating, nanoscale-confined heating (NCH) and macroscale-collective heating (MCH), have been found and extensively studied. Despite this, the resulting…

Until recently traditional heating in organic chemistry has been done with oil heating baths or using electric heat exchangers. With the advent of microwave equipment, heating by microwaves was rapidly introduced as standard method in organic chemistry laboratories, mainly because of the convenient possibility to…

In China, research on winter heating and energy saving for residential buildings mainly focuses on urban residences rather than rural ones. According to the 2018 China Building Energy Consumption Research Report, rural residential buildings emit about 423 million tons of carbon, accounting for 21% of the country’s…

Optical microheating technologies have revealed how biological systems sense heating and cooling at the microscopic scale. Sensing is based on thermosensitive biochemical reactions that frequently engage membrane proteins, Ca^2+^ channels, and pumps to convert sensing information as the Ca^2+^ signaling in cells. These…

'Pengfei Hu' 'Zhenlin An'] Electric heaters are widely used owing to their portability, fast heating, single-focus heating, and energy efficiency advantages. Manufacturers provide customers with information on the power consumption and energy efficiency classes of heaters but do not provide any information on heating…

As anthropogenic CO2 emissions responsible for our changing climate continue to rise, new technologies are needed to reduce their impact. Direct Air Capture (DAC) is a developing technological solution whereby CO2 is captured directly from ambient air and later released in a controlled manner for further use or…

Thermal desorption measurements, including thermal desorption mass spectrometry, are often used to determine the volatility and chemical composition of secondary organic aerosol (SOA). Accurately interpreting such measurements requires understanding the response of SOA to heat. Using optical microscopy, we monitored…

Temperature control is a key aspect of macromolecular crystallography, with the technique of cryocooling routinely used to mitigate X-ray induced damage. Beam induced heating could cause the temperature of crystals to rise above the glass transition temperature, greatly increasing the rate of damage. X-ray induced…

We explore transient heat transfer, on the millisecond time–scale, from a narrow, rectangular stainless steel heater cooled from one side by He II confined to a channel of 120 µm depth. The helium is isolated from the external bath with the exception of two pin–holes of cross section about 10% that of the channel.

Gas boilers dominate domestic heating in the UK, and significant efficiency improvements have been associated with condensing boilers. However, the potential remains for further efficiency improvement by refining the control, system specification and installation in real dwellings. Dynamic building simulation…

Heating, ventilation, and air-conditioning (HVAC) systems are major contributors to global energy consumption, underscoring the urgent need for energy-efficient building envelope technologies. Synergistic solar and radiative electrochromism offers a promising solution by leveraging the sun and outer space as…

'John A. Paravantis' 'Sofoklis S. Makridis' 'Spiros Papaefthimiou'] The building sector is responsible for 40% of primary energy consumption, with heating/cooling covering the most significant portion. Thus, passive heating/cooling applications have gained significant ground during the last three decades, with many…

Understanding the thermomechanical behavior of heterogeneous polymer systems is crucial for material design. Herein, we introduce a novel technique that couples chemistry-selective infrared (IR) heating with atomic force microscopy (AFM) nanomechanical measurements. We demonstrate that surface temperature of the sample…

The use of biofuels is becoming an increasingly important part of national and corporate climate strategies. At the same time, the consumption-based biodiversity impacts of biofuels are generally poorly known. Here we used a consumption-based approach to assess the biodiversity impacts of peat and wood-fired district…

On the long nuclear time scale of stellar main-sequence evolution, even weak mixing processes can become relevant for redistributing chemical species in a star. We investigate a process of "differential heating," which occurs when a temperature fluctuation propagates by radiative diffusion from the boundary of a…

Short review on the different models for the electro-thermal 3-omega method. We present the deduction of the fundamental relation between the 3ω voltage with the temperature rise to determine the thermal conductivity. The usage of the anisotropy of the films allows a smooth transition between 1D and 2D models. A…

We propose a mechanism of active near-field heat transfer modulation relying on externally tunable metamaterials. A large modulation effect is observed and can be explained by the coupling of surface modes, which is dramatically varied in the presence of controllable magnetoelectric coupling in metamaterials. We…
