Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. . This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and ...
A thrombin generation assay (TGA) or thrombin generation test (TGT) is a global coagulation assay (GCA) and type of coagulation test which can be used to assess coagulation and thrombotic risk. [ 1 ] [ 2 ] [ 3 ] It is based on the potential of a plasma to generate thrombin over time, following activation of coagulation via addition of ...
Polymers represent another large area in which thermal analysis finds strong applications. Thermoplastic polymers are commonly found in everyday packaging and household items, but for the analysis of the raw materials, effects of the many additive used (including stabilisers and colours) and fine-tuning of the moulding or extrusion processing used can be achieved by using differential scanning ...
This is a deeper peel than the beta hydroxy acid peel and is used to treat scars, wrinkles, and pigment. It is usually performed in conjunction with a Jessner; which is performed right before, in order to open up the skin, so the retinoic acid can penetrate deeper into the skin. The client leaves with the chemical peel solution on their face.
Throughout the past 10 years, minimally invasive dermatological procedures have shown significant advancements, with the emergence of intradermal fillers, botulinum toxin injections and chemical peels. [35] These techniques require smaller incisions, which could lessen scarring and trauma, and decrease surgical complications. [36]
Differential thermal analysis (DTA) is a thermoanalytic technique that is similar to differential scanning calorimetry.In DTA, the material under study and an inert reference are made to undergo identical thermal cycles, (i.e., same cooling or heating programme) while recording any temperature difference between sample and reference.

Thioglycolic acid (TGA) is the organic compound HSCH 2 CO 2 H. TGA is often called mercaptoacetic acid (MAA). It contains both a thiol ( mercaptan ) and carboxylic acid functional groups. It is a colorless liquid with a strongly unpleasant odor .
Plasma activation (or plasma functionalization) is a method of surface modification employing plasma processing, which improves surface adhesion properties of many materials including metals, glass, ceramics, a broad range of polymers and textiles and even natural materials such as wood and seeds.
