Thermoelectric Effects in S-N-S Weak Links with Heavy Fermions as The Normal Metal: A Possibility for Thermosensors
نویسنده
چکیده
It is shown that S-N-S weak links with an heavy-fermion metal as the weak link (N) can be useful thermosensors. This property is due to the large thermopower of heavy-fermion metals which is of the order 10−6 V/K. The longitudinal sound can also generate voltage oscillation due to the large Grüneisen parameter, Ωhf ∼ 10 2, in heavy-fermions. Similar effects are expected with other Kondo systems as the weak link.

Removal of heavy metal (copper) using Microalgae (Spirulinaplatensis) by Taguchi Method
Environmental pollution by heavy metals is one of the main problems in the environment. Biosorption, is inactivated or live and dead biomass is used for the removal of heavy metals. In this study, a micro alga (Cyanobacteria) Spirulina platensis was used as adsorbents for the remediation of copperfrom aqueous solution.The purpose of this research is to study the possibility or impossibility of...
متن کاملConcentration of Heavy Metals in Drinking Water Sources of Karaj in 2017: A Descriptive Study
Background and Objectives: Heavy metals enter water supply sources in different ways such as natural or artificial and when they enter the food chain and accumulate in tissues, they cause harmful effects on human health. Therefore, the aim of this study was to determine the concentration of heavy metals in drinking water sources in Karaj and compare it with national standards. Materials and Me...
متن کاملA Renormalization Group Analysis of the Higgs Boson with Heavy Fermions and Compositeness
We study the properties of heavy fermions in the vector-like representation of the electro-weak gauge group SU(2)W × U(1)Y with Yukawa couplings to the standard model Higgs boson. Using the renormalization group analysis, we discuss their effects on the vacuum stability and the triviality bound on the Higgs self-coupling, within the context of the standard model (i.e., the Higgs particle is ele...

متن کاملConvenient and Efficient Elimination of Heavy Metals from Wastewater Using Smart Pouch with Biomaterial
A newly developed Smart Pouch with enclosed biomaterial (Aloe vera and coconut husk powder) has been experimented for elimination of heavy metals i.e. (Pb2+, Cu2+, Ni2+ and Zn2+) from wastewater. The effect of concentration, pH, temperature, contact duration etc. was investigated using batch experiments which resulted that the Pouch may be accepted for convenient, efficient and low-cost accumul...
