Enhancement of thermoelectric power factor in Cu2Se superionic conductor via high energy electron beam irradiation

High Thermoelectric Power Factor of High‐Mobility 2D Electron Gas

Thermoelectric conversion is an energy harvesting technology that directly converts waste heat from various sources into electricity by the Seebeck effect of thermoelectric materials with a large thermopower (S), high electrical conductivity (σ), and low thermal conductivity (κ). State-of-the-art nanostructuring techniques that significantly reduce κ have realized high-performance thermoelectri...

The effect of high-energy electron beam on drawn and undrawn high density polyethylene fibers

HDPE monofilaments were obtained using different extruders and drawn by post-extruder equipments. After solidification, drawn and undrawn monofilaments (draw ratio 7:1) were irradiated with 10 MeV electron beams in air at room temperature at 25, 50, 75, 100 and 125 kGy dose ranges to induce a network structure. HDPE crosslinking was studied on the basis of gel content measurements. The fibers w...

Electron energy filtering by a nonplanar potential to enhance the thermoelectric power factor in bulk materials

emittance control in high power linacs

چکیده این پایان نامه به بررسی اثر سیم پیچ مغناطیسی و کاوه یِ خوشه گر با بسامد رادیویی بر هاله و بیرونگراییِ باریکه هایِ پیوسته و خوشه ایِ ذرات باردار در شتابدهنده های خطیِ یونی، پروتونی با جریان بالا می پردازد و راه حل هایی برای بهینه نگهداشتن این کمیتها ارایه می دهد. بیرونگرایی یکی از کمیتهای اساسی باریکه هایِ ذرات باردار در شتابدهنده ها است که تاثیر قابل توجهی بر قیمت، هزینه و کاراییِ هر شتابدهند...

Electron Beam Irradiation Applications

The irradiation of materials with electron beams or X rays is used extensively to enhance or modify their physical, chemical or biological properties. These electron beam “irradiators” cover a very wide range of accelerators technology, beam current and energies to produce a wide variety of products, mostly with polymers. They also are used for curing ink, coatings, and adhesives as well as for...
