Effect of Temperature on the Viscosity of Raw and Boiled Honey: A Study from Tabora, Tanzania | Chapter 4 | Atomic Absorption Spectroscopy and Physical Experiences in Morogoro, Tanzania

 

Honey is a sweet-smelling fluid with a viscous character. Viscosity is a property of fluid by virtue of which a frictional force acts tangentially on the layers of the fluid in motion. The study aimed at investigating and determining the viscosity of the raw and boiled honey from Tabora, Tanzania, at constant and different temperatures. The method of Stokes’ law has been employed in the study. The physical properties, especially the viscosity of raw honey and boiled honey, were determined. Finally, the study revealed types of honey in raw or boiled form that can be used for medical, industrial, business, and food processing. Viscosity is a measure of a fluid's resistance to the movement of a mass through. Honeys viscosity varies with the amount of water, sugar and type. It is determined in this work that the variations in temperature change the viscosity of honey. The viscosity is lowered when honey is heated. The results of this study indicate that Tanzanian honey samples compare well with samples in many parts of the world. The quality of Tanzanian honeys has medicinal, nutritional, antioxidant and viscosity values. The temperature influence on viscosity in honey types is valuable for setting scientific benchmarks for distinguishing raw honey from heat-processed honey, as well as for food processing and packing. The physical properties of honey strengthen knowledge to support improvements in honey handling, storage, and industrial use.

Advancements and Future Directions in Thermal Barrier Coatings: A Comprehensive Review | Chapter 6 | Chemical and Materials Sciences: Developments and Innovations Vol. 8

Thermal barrier coatings (TBCs) protect engine parts of aircraft and industrial gas turbines. TBC system is a complex structure comprising several metal and ceramic-based layers. The structure as well as composition of TBCs determine their properties during actual applications. TBCs are usually prepared by the atmospheric plasma spraying method, which is more cost-effective than other techniques. Bilayered, multilayered and functionally graded TBCs have been proposed by the researchers to achieve enhanced coating performance. The current review paper is focused on the state of the art of recent TBC materials, design and fabrication techniques. Attempt has also been made to make a comparative study on existing TBC materials. Future perspectives have been put forward based on the present status.

Study of the Thermal Properties of Raffia Bamboo Vinifera L. Arecaceae: Current Developments | Chapter 7 | Emerging Trends in Engineering Research and Technology Vol. 1

 Raffia is a somewhat fast-growing touch tree, from the family of Arecaceae, attacked in marshy regions and along waterways. In this study, the “Raffia Bamboo” is the stalk of a palm, made of a dainty marrow inside a thin structure, smooth and hard to protect the latest. In our region, this material is widely used to build all the cheap traditional families and furniture, to create granaries storage of dry products, to build hen coops, to make ribbon. Tus, various tasks are organized around this material, accompanying the fight against poverty. To our information, information on allure thermal properties is nearly nonexistent. The exploratory determination of the transverse warm properties of the dry shell, the dry essence, and the whole dry bamboo assisted to find, for each, a heat required to raise temperature, a thermal diffusivity, a thermal generated power, and finally a warm effusivity. From the analysis of results, we understand that the thermal properties of raffia bamboo Vinifera L. Arecacea manage a very good warm insulator.

A Comparative Study on Phonon Spectrum and Thermal Properties of Graphene, Silicene and Phosphorene: Recent Advances and Development | Chapter 7 | Current Perspectives on Chemical Sciences Vol. 10

 We examine the vibrational and thermal properties of two-dimensional honeycomb lattices of graphene, silicene, and black phosphorene using first-principle calculations utilising density functional theory. We concentrate on the similarities and contrasts in their qualities, attempting to deduce their meaning from their lattice structures. We show that in silicene and black phosphorene, a phonon band gap forms, effectively reducing phonon thermal conductivity. Positive frequencies are present in all three systems (graphene, silicene, and black phosphorene), ensuring structural stability. We also discovered that at very low temperatures, specific heat, entropy, and free energy for all systems grow fast, but specific heat (Cv) remains constant at higher temperatures.
