Thermopause
A term used in medicine and physiology.<br><br>The thermopause is the midpoint of the body's thermogenesis, or heat production, during a 24-hour period.

Thermophoresis
Thermophoresis is the phenomenon where there is a movement of particles or molecules from a region of higher temperature to a region of lower temperature in a medium, usually a fluid, in the presence of a temperature gradient. This movement is driven by the temperature difference, and it is a type of diffusion process. In other words, particles or molecules tend to migrate from the warmer area to the cooler area due to the temperature gradient, without the need for a physical force or pressure difference.<br><br>Thermophoresis is often observed in liquids, such as gels, colloids, or powders, and it can be caused by various factors, including heat transfer, changes in viscosity, or molecular interactions. The phenomenon has applications in fields like materials science, nanotechnology, and biotechnology, where it is used to separate, manipulate, or concentrate particles or molecules based on their size, shape, or properties.<br><br>In a more general sense, thermophoresis can be observed in everyday life, such as when a cool breeze blows away heat from the skin, or when a fan circulates cooler air to reduce the temperature in a room. However, in scientific contexts, thermophoresis typically refers to the specific phenomenon where particles or molecules move in response to a temperature gradient, often driven by forces such as electrostatic or van der Waals interactions.
Thermophoretic
The term "thermophoretic" refers to the effect or process of particles or substances moving due to the transfer of heat. This phenomenon occurs when there is a temperature difference between the particles or substances and their surroundings, causing them to move towards or away from the heat source.<br><br>Thermophoresis, also known as thermophoretic levitation, is a related concept that involves the movement of particles at the surface of a material when heated, which can lead to a reduction in surface roughness and improve the quality of various materials.
Thermophylic

Thermoscope
A thermoscope is a device that measures temperature, but does not have a visible temperature scale. It is an early precursor to the development of thermometers, which can display temperature readings.<br><br>Historically, thermoscopes were used in the early 17th century, before the invention of thermometers with a calibrated scale. They were essentially empty containers with a liquid that expanded or contracted in response to heat changes, making it possible to approximate temperature readings.<br><br>In practice, thermoscopes were not very accurate, and it wasn't until the invention of the mercury thermometer by Sanctorius in 1612 that temperature readings could be taken with more precision.<br><br>Today, thermoscopes are of largely historical interest, as thermometers have become the standard instrument for measuring temperature.
Thermoses
There is no word "thermoses" in the English language. However, the word "thermos" is related to the concept.<br><br>A thermos is a vacuum-insulated container that keeps liquids at a consistent temperature, either hot or cold, for a relatively long period.

Thermoset is a type of plastic material that is formed by a chemical reaction and cannot be melted or reshaped once it has been molded. It is typically used in products such as composites, adhesives, and coatings. Thermosets have a fixed shape and can be brittle, but are often resistant to heat, chemicals, and wear. Examples of thermoset products include fiberglass, rubber, and epoxy.
Thermosetting
A thermosetting is a type of material that becomes fixed in shape and cannot be melted or reshaped once it has been formed. It is created when a polymer undergoes a chemical reaction that leads to the formation of a three-dimensional network of molecules, making it rigid and permanent. Thermosetting materials are commonly used in a wide range of applications, including plastics, resins, fibers, and adhesives, and are often used in production of electronic components, automotive parts, and construction materials. Examples of thermosetting materials include epoxy, polyesters, and polyurethanes.
Thermosiphon
A thermosiphon is a device or a system that uses buoyancy and gravity to circulate a fluid, typically a liquid or gas, through a series of tubes or channels without the need for a pump. It relies on the principle of density difference between two or more fluids to create a circulation.<br><br>The term "thermosiphon" typically refers to a cooling system that uses a liquid coolant, such as water or a mixture of water and other fluid, to cool a hot object or a piece of equipment. In this application, the thermosiphon is a type of passive cooling system that uses natural convection to circulate the coolant through a series of tubes or channels, often a coil or shell-and-tube configuration.<br><br>The thermosiphon relies on the reducing temperature of the coolant as it flows from the top to the bottom of the system, resulting in the coolant's density decreasing and the warmer coolant being drawn upwards, which in turn creates a circulation loop. This type of system is commonly used to cool electronic components, especially in industrial applications, automotive engines, and nuclear power plants.<br><br>In a broader sense, the term "thermosiphon" can be applied to any system or device that uses a similar principle to circulate a fluid or gas through a series of tubes or channels, such as vacuum systems, chemical processing equipment, and more.

Thermosol is a type of preservation method using high-temperature short-time (HST) steam sterilization, also known as flash sterilization or flash heat sterilization. It is commonly used in medical and dental settings to sterilize equipment and instruments. The process involves exposing the items to a blast of steam for a short period, typically between 3-10 minutes, to kill bacteria, viruses, and other microorganisms. Thermosol sterilization is effective against a broad spectrum of pathogens and is often used for self-disposable instruments, equipment, and patient care items.

In other words, it describes the degree to which a substance can maintain its stability and activity at varying temperatures, from cold to hot.<br><br>Thermostability is an important property in various fields, such as medicine, biotechnology, and food processing, where enzymes and other biochemicals are used to catalyze reactions or as therapeutic agents.
Thermostabilized
Thermostabilized refers to a process or product that has been treated with heat to extend its shelf life and prevent the growth of microorganisms, bacteria, or enzymes. This is often done through techniques like retorting or autoclaving, where food or other products are heated to a high temperature for a prolonged period of time to kill off any potential contaminants and preserve the product for a longer period. This can be seen in the sterilization of vaccines, pharmaceuticals, and certain types of food, such as canned goods or infant formula. The goal of thermostabilization is to create a product that remains safe and effective for a longer time, which can be crucial in various industries such as medicine, food production, and biotechnology.
