Summary
This study introduces novel thermoreversible adhesives with crystalline domains for precise thermal switching. These adhesives offer high bonding strength and stability, enabling on-demand temporary fixation with controlled debonding.
Area of Science:
- Materials Science
- Polymer Chemistry
- Adhesion Science
Background:
- Thermoreversible adhesives enable temporary fixation, reducing costs and environmental impact.
- Existing materials suffer from imprecise thermal switching, high detachment temperatures, and poor stability.
Purpose of the Study:
- To develop advanced thermoreversible adhesives with enhanced performance.
- To address limitations of current thermoreversible adhesive technologies.
Main Methods:
- Incorporation of temperature-responsive crystalline domains into adhesive formulations.
- Characterization of adhesive properties including lap shear strength, bonding stability, and thermal detachment behavior.
Main Results:
- The new adhesive exhibits high lap shear strength (5.38 MPa) and stable bonding (over 75% of initial value from 30-70 °C).
- Achieved suitable thermal detachment temperature (∼80 °C, 0.66 MPa) and high environmental reliability.
- Demonstrated precise thermal switching near the melting temperature of crystalline domains (Tm).
Conclusions:
- The developed thermoreversible adhesive offers a feasible strategy for precision control in bonding and debonding.
- This innovation is conducive to promoting thermoreversible adhesives in temporary fixation applications.

1.2K
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

4.9K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

1.5K
Body temperature reflects the equilibrium between heat production and heat loss within the body. Most heat is generated by metabolically active tissues, particularly the liver, heart, brain, kidneys, and endocrine organs. At rest, skeletal muscles contribute 20–30% of total heat production, but during vigorous exercise, this can increase up to 30–40 times.
The average body temperature is approximately 37°C (98.6°F) and typically ranges from 36.1–37.2°C...

02:11Effects of Temperature on Free Energy
28.5K
The spontaneity of a process depends upon the temperature of the system. Phase transitions, for example, will proceed spontaneously in one direction or the other depending upon the temperature of the substance in question. Likewise, some chemical reactions can also exhibit temperature-dependent spontaneities. To illustrate this concept, the equation relating free energy change to the enthalpy and entropy changes for the process is considered:

A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...
