Assessment of two-level heat pump installations’ power efficiency for heat supply systems
Trudy Odesskogo Politehničeskogo Universiteta, 2015 The problem of energy saving becomes one of the most important in power engineering. It is caused by exhaustion of world reserves in hydrocarbon fuel, such as gas, oil and coal representing sources of traditional heat supply.

Quantum heat fluctuations of single particle sources
, 2012 Optimal single electron sources emit regular streams of particles, displaying no low frequency charge current noise. Due to the wavepacket nature of the emitted particles, the energy is however fluctuating, giving rise to heat current noise.

Exploitation of Excess Low-Temperature Heat Sources from Cogeneration Gas Engines
, 2022 The chapter presents an innovative technical solution for the use of low-temperature excess heat from the combined heat and power (CHP) of gas engines using gas or liquid fuel for district heating, building heating or industry. The primary fuel efficiency of CHP gas engines for heat production can be significantly increased by using the low-temperature

Spin-catalyzed hopping conductivity in disordered strongly interacting quantum wires [PDF]
, 2016 In one-dimensional electronic systems with strong repulsive interactions, charge excitations propagate much faster than spin excitations. Such systems therefore have an intermediate temperature range [termed the "spin-incoherent Luttinger liquid'" (SILL)
