Thermodynamic and ecological preselection of synthetic fuel intermediates from biogas at farm sites

Energy, Sustainability and Society, 2020
Background Synthetic fuels based on renewable hydrogen and CO2 are a currently highly discussed piece of the puzzle to defossilize the transport sector. In this regard, CO2 can play a positive role in shaping a sustainable future.

Improving carbon efficiency and profitability of the biomass to liquid process with hydrogen from renewable power

Fuel, 2018
A process where power and biomass are converted to Fischer-Tropsch liquid fuels (PBtL) is compared to a conventional Biomass-to-Liquid (BtL) process concept.

Stopping Power of Electron Liquid for Slow Quantum Projectiles [PDF]

Contributions to Plasma Physics
We revisit the problem of the deceleration of a charge moving in a medium. In the low‐velocity limit of the projectile, we construct the fully nonlinear (in the charge–target interaction) theory of the stopping power (SP), which goes beyond the ...

Downsizing Sustainable Aviation Fuel Production with Additive Manufacturing—An Experimental Study on a 3D printed Reactor for Fischer-Tropsch Synthesis

Energies, 2023
Sustainable aviation fuels (SAF) are needed in large quantities to reduce the negative impact of flying on the climate. So-called power-to-liquid (PtL) plants can produce SAF from renewable electricity, water, and carbon dioxide.

Temperature field in a cylindrical porous layer during “endless” heating with heat outflow

Известия высших учебных заведений: Проблемы энергетики
RELEVANCE. This article proposes a mathematical model for calculating the temperature field in the annular porous layer of an downhole reactor during continuous heating of a bottomhole zone containing high-viscosity oil (VVN) and natural bitumen (PB ...

System Dynamic Model for the Accumulation of Renewable Electricity using Power-to-Gas and Power-to-Liquid Concepts

Environmental and Climate Technologies, 2015
When the renewable energy is used, the challenge is match the supply of intermittent energy with the demand for energy therefore the energy storage solutions should be used. This paper is dedicated to hydrogen accumulation from wind sources.

Advanced liquid crystal devices for augmented reality and virtual reality displays: principles and applications

Light: Science & Applications, 2022
Liquid crystal displays (LCDs) and photonic devices play a pivotal role to augmented reality (AR) and virtual reality (VR). The recently emerging high-dynamic-range (HDR) mini-LED backlit LCDs significantly boost the image quality and brightness and ...

Progressive Multifocal Liquid Lenses Based on Asymmetric Freeform Surface Structure of Nonuniform Thickness Elastic Membranes with Different Constraints

International Journal of Optics, 2019
For a progressive multifocal liquid lens with an elastic membrane deformed by liquid pressure, to realize a reasonably power distribution, asymmetric deformation characteristics of the membrane surface are needed. Based on the asymmetric freeform surface

Liquid Time-constant Networks [PDF]

AAAI Conference on Artificial Intelligence, 2020
We introduce a new class of time-continuous recurrent neural network models. Instead of declaring a learning system's dynamics by implicit nonlinearities, we construct networks of linear first-order dynamical systems modulated via nonlinear interlinked ...
