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.

Lovely dress. Good quality but squashes my boobs
Size: Small, Color: Navy Polka Dot
Size chart is accurate but if you have a large bust consider sizing up, the bust area doesn’t have much room so expect lots of cleavage if you have a large chest. It kind of squashed my boobs and doesn’t provide the best support. This is best for smaller chests. The quality is nice and it washes well. This can be worn with flats on a casual day or dresses up with some heels. This dress is lined and not see through.

My favorite this summer
Size: 9, Color: Red Leather, Size: 9, Color: Red Leather
These are very nice. I like this type of sandal with the "thong" feature while also having my foot gently hugged. These did not require much breaking in, seemed pretty comfortable from the first wear. I wore them to a high-end rooftop restaurant with a chiffon and silk maxi dress, and it worked really well, got compliments and all, though I have no good shots from there with these sandals visible. The red color definitely makes them pop, especially with black elements of the outfit. I also got them in black here, and in white from another store. Their shape is delicate, yet sharp and stylish, and they seem to be well-made. When I got these shoes, I took them to my artistic shoe repair guy, to promptly put protective layer on the front bottom of the soles. That way, it always looks like new, no scratched sole. That costs a bit, but worth it for me. I might buy a pair or two in some other colors, later. I am 5'10" tall, clothes size M, shoes - 9, 150lb. These shoes feel true to size.

Size up! Super comfortable!
Size: 10, Color: Black Leather
Super comfortable, can walk al night in them. I size up in anything steve madden. I’m usually a 9, but a 9.5 in steve madden fits almost exact so I get a size 10 in any of their shoes. Sizing is consistent throughout styles but I def need to size up. If you’re in between sizes, I suggest a whole size up. Unless you like an exact fit, personally I think an exact fit looks off any slight movement of your foot and the shoe looks like it doesn’t fit. I would say they’re pricey but they’re def a classy and comfortable pair of heels!

Good
Size: 7, Color: Black Leather
Cute , you’ll need to break them in. If you have wide feet theses probably aren’t for you Over all as shown , true to size
