Product Overview

 

Thermoelectric materials are functional materials that can convert thermal and electrical energy by utilizing their internal charge carriers and phonons. The effective operation of thermoelectric materials is mainly based on three physical effects, namely the Seebeck Effect (discovered in 1794, referring to the phenomenon of thermal to electrical conversion between two different conductors), the Peltier Effect (discovered in 1834, the phenomenon of electrical to thermal conversion between two different conductors), and the Thomson Effect (discovered in 1851, the phenomenon of heat absorption and release in a single conductor).

The conversion efficiency of thermoelectric materials is determined by the dimensionless parameter - thermoelectric figure of merit ZT, and its calculation formula is:

ZT=σ S2T/k, where σ is the conductivity, S is the Seeback coefficient, which is the inherent electronic transport performance parameter of thermoelectric materials, T is the temperature, and k is the total thermal conductivity. A common method to improve the performance of thermoelectric materials is to introduce multi-scale second phases to regulate the microstructure of thermoelectric materials, thereby changing the band structure and crystal structure of the matrix to coordinate various parameters and optimize their thermoelectric transmission performance.

Traditional inorganic thermoelectric materials are currently a type of thermoelectric material with a wide range of applications and a long research time. Mainly including Mg based thermoelectric materials (Mg2X (X=Si, Sn)), Bi2Te3 based thermoelectric materials, SiGe based thermoelectric materials, PbX (X=S, Se, Te) based thermoelectric materials, SnX (X=S, Se) based thermoelectric materials, GeTe based thermoelectric materials, and oxide based thermoelectric materials.

PbTe based thermoelectric materials are thermoelectric materials in the medium temperature range, exhibiting excellent thermoelectric properties in the temperature range of 300-900K. Its bandgap width is about 0.3 eV, belonging to wide bandgap semiconductors, with a typical NaCl type crystal structure, highly symmetrical crystal structure, and high conductivity. At the same time, its band structure is also relatively complex, and the strong non harmonic vibration caused by local eccentricity of Pb atoms makes PbTe have low thermal conductivity while having a high Seebeck coefficient.

A well done graphic novel for children
Format: Hardcover
A graphic novel for middle and high schoolers that personifies animals vis-a-vis “Animal Farm”. The illustration is well done and the prose is easily understandable by children. An adult will probably be needed to explain the metaphors.

Modern Day Animal Farm
Format: Paperback
📚Animal Pound ✍🏻Tom King Blurb: When animals grow tired of being caged and abused, it’s only a matter of time before they have nothing to lose but their cages… When an uprising puts a pound in control of the animals, they make quick comrades, united against everything that walks on two legs. But with this newfound power comes a sudden challenge: how best to lay the groundwork for this new democracy as they write their first constitution. The conditions are ripe for a dictator, primed for instating a new system of brutality and death. When two groups of animals work together will their efforts be enough to prevent further animal authoritarianism? Discover a timely graphic storytelling event from celebrated New York Times bestselling, Eisner Award-winning writer Tom King (The Human Target, Love Everlasting) and New York Times bestselling, Eisner Award-nominated artist Peter Gross (American Jesus, The Books of Magic), collaborating for the first time ever to bring this enduring Orwellian allegory to life for the 21st Century. Collects Animal Pound #1-5. My Thoughts: A retelling of Animal Farm but for modern audiences. Instead of focusing on the dangers of communism, it instead focuses on the dangers of fascism. I would say it's very heavy-handed in its obvious critique of the MAGA crowd, but also frightfully accurate and does very well at evoking emotion from you, the reader, who probably also just like me, would be very frustrated watching everyone fall for the the DJT-allegory.. This is the rare graphic novel meant to be given to non comics readers. Thanks NetGalley, BOOM! Studios and Author Tom King for the advanced copy of "Animal Pound" I am leaving my voluntary review in appreciation. #NetGalley #Boom!Studios #AnimalPound #TomKing ⭐️⭐️⭐️⭐️

Modern Day Animal Farm
Format: Hardcover
This is a MUST read, quickly, before it is banned. King captures the modern political landscaper perfectly from the blind cult like following to the concerned and ignored, to the bullying, violence and normalization of the bizarre. This may be the most important Graphic Novel of the last 25 years. Were I a wealthy man I would purchase a copy for every American History Classroom.
