Engineers at CSEM have developed a new machine-learning method that paves the way for artificial intelligence to be used in applications that until now have been deemed too sensitive. The method, which has been tested by running simulations on a climate-control system for a 100-room building, is poised to deliver energy savings of around 20%.
Producing biogas from the bacterial breakdown of biomass presents options for a greener energy future, but the complex composition of biomass comes with challenges. Cellulose and woody lignocellulose are especially hard for bacteria to digest but pretreatment can make it easier. Researchers are testing plasma formation in biomass and finding a promising method: A plasma-liquid interaction forms reactive species that help break down the biomass and decrease the viscosity of the biomass material.
The discovery could help battery researchers design the first solid electrolytes that are safe, cheap and efficient.
Scientists at Oak Ridge National Laboratory used new techniques to create a composite that increases the electrical current capacity of copper wires, providing a new material that can be scaled for use in ultra-efficient, power-dense electric vehicle traction motors.
By studying 488 public airports in the United States, University of Colorado Denver School of Public Affairs researcher Serena Kim, PhD, found that 20% of them have adopted solar photovoltaic (PV), commonly known as solar panels, over the last decade.
IIASA researchers have developed a novel measurement framework to track energy poverty that better aligns with the services people lack rather than capturing the mere absence of physical connections to a source of electricity. This alternative framework can aid better tracking of Sustainable Development Goal (SDG) 7 by virtue of its simplicity and sensitivity to the diversity in service conditions among the poor.
New paper in Nature Energy, reveals how researchers fully identified the nature of oxidised oxygen in the important battery material - Li-rich NMC - using RIXS (Resonant Inelastic X-ray Scattering) at Diamond Light Source. This compound is being closely considered for implementation in next generation Li-ion batteries because it delivers higher energy density than current materials, and could translate to longer driving ranges for electric vehicles and enable scientists to tackle issues like battery longevity and voltage fade
While the power conversion efficiency of perovskite solar cells (PVSCs) has already greatly improved in the past decade, the problems of instability and potential environmental impact are yet to be overcome. Recently, scientists from City University of Hong Kong (CityU) have developed a novel method which can simultaneously tackle the leakage of lead from PVSCs and the stability issue without compromising efficiency, paving the way for real-life application of perovskite photovoltaic technology.
Copper stearate was used as the basis for this catalyst test and showed efficiency for in-situ oil combustion.
The fixed fluidized bed technology is already widely used overseas, but is relatively new for the Russian oil industry. To improve it, the KFU scientists mixed coke particles with quartz sand. This created a sort of a "freeze" in the porous layer and simplified the study of the kinetics of petroleum coke combustion in the presence of catalysts.
