We accepted a paper reviewing the sealing performance of microbially induced carbonate precipitation and its engineering application. The importance of sealing micro-fractures in an environmentally friendly and efficient manner is emphasized, and the potential of the MICP method in controlling pore and fracture seepage is highlighted. The fundamental mechanisms, key influencing factors, numerical models, and applications of the MICP in the fields of geological CO2 storage and oil resources development are comprehensively summarized.

I'm excited to announce the publication of our manuscript, "Suppressing the Thermal Conductivity to Enhance the Thermoelectric Performance of SnSe2 using the High-Energy Ball Milling in a Pressurised N2 Atmosphere," in the Journal of Materials Research and Technology. We significantly improved the thermoelectric (TE) performance of 2D layered SnSe2 by reducing particle size from ～2 μm to 100 nm using high-energy ball milling in a pressurized N2 atmosphere. This process increased electrical conductivity ninefold at room temperature (RT) while reducing the Seebeck coefficient by only 40%, boosting the power factor from 12 to 42 μW/m·K2. Thermal conductivity decreased from 5.72 to 0.40 W/m·K, raising the figure of merit fortyfold. Single-leg modules showed higher power generation, especially below RT, with the 7-h milled module generating 2600 nW at ΔT = 45 K above RT and 8000 nW below RT, demonstrating potential for cold environments. https://lnkd.in/dCzbRusM

I am happy to announce that today I will be presenting our lastest work on porous media combustion at the 40th ICS in Milan. The article is entitled?"Speed-up drivers for H2-enriched flames in porous media burners" and is authored by E. Flores-Montoya, Pierre-Alexandre MASSET, thierry schuller and L. Selle. This paper discusses the influence of hydrogen enrichment on flame stabilization in porous media burners. The flame-front tracking methodology is applied in optically?accessible burners with different porosities. H2 is found to shift the stability maps towards leaner equivalence ratios and to change the stabilization trend of flames within the porous burner. Using a theoretical model to remove the sensitivity to preheating indicates that heat recirculation alone cannot explain the increase of the speed up and points out to the existence of other combustion enhancement mechanisms in?H2-enriched flames. The article has also been accepted for publication in the Proceedings of the Combustion Institute and will be available soon. The oral presentation will take place today at 17:30

We are pleased to announce that our joined paper “Viscous Fingering in CCS - A General Criterion for Viscous Fingering?in Porous Media” has been accepted for publication in the International Journal of Greenhouse Gas Control. ? For many practical applications such as the CO2 injection for carbon capture and sequestration (CCS) or gas injection for underground energy storage it is important to understand whether a displacement is stable or unstable. ? The new criterion is particularly useful for CCS applications on laboratory scale and also field scale, and the paper discusses how, depending on exact pressure and temperature conditions, CCS can be viscous-unstable. ? Unstable displacement may lead to CO2 plume migration beyond a spill point and in that way may reduce the storage capacity. The paper discusses how the new criterion impacts the design of the laboratory experiments as well as how it can be used in the design of the gridding of field-scale simulations. ? ?Article link: https://lnkd.in/ght4YriS Activate to view larger image,

Safety of Commercial Sodium-ion Cells with Judith Jeevarajan from UL Research Institutes. This presentation will cover how: Commercial Na-ion cells were tested for performance and safety at ESRI. Performance tests included two different charge/discharge rates and three different temperatures. Safety tests included overcharge, overdischarge, external short circuits, and heating tests. The results of the research studies will be presented. https://lnkd.in/e_YenNds Save $150 with Discount Code SPK150. #Floridabattery

Revolutionizing Oxidation Reactions with Continuous Flow Chemistry ???? We are excited to share the work of Marcus Baumann & Ruairi Bannon about innovative continuous flow method for aerobic photo-oxidation of benzylic substrates!?? ?? By leveraging UV-A LEDs and a Corning Advanced-Flow reactor, they’ve achieved efficient gas liquid mixing and ultra-short residence times of less than one minute. This innovative method delivers yields of up to 83% with a productivity rate of 8 mmol/h. The use of greener and safer conditions, combined with process intensifications principles, makes this flow approach particularly appealing for further industrial application.? ??Learn more about this experience here : https://lnkd.in/eH6yT6zY

For the MEC II program, we test the circularity of the chain in our Future Energy Lab in Budel (NL). We start with a certain amount of powder, burn it in the MP500, and reduce the combustion product (rust) in the Rotating Drum that will soon be built in the hydrogen lab. And we repeat that round again and again ?? Each round we do powder analyses to determine values such as the degree of oxidation of the rust and the reduced powder. These measurements, supplemented with particle size measurements, help us determine the extent to which we can circulate the powder safely, reliably and while maintaining performance in real situations ??

When floating photovoltaic (FPV) panels are deployed in reservoirs, it is crucial to predict the motion and hydrodynamic loads on the panels caused by incoming currents. This prediction is essential for ensuring the safe operation of FPV systems, particularly during water releases from the reservoir. Dr Luofeng Huang and I formed the idea to study this question last year when I visited him at Cranfield University. Recently, we published a paper in the journal Physical Review Fluids, in which a theoretical model is proposed to investigate this topic: https://lnkd.in/eXw7xZER. In the paper, by modelling the entire FPV system as a semi-infinite elastic plate, we used an analytical approach – the Wiener-Hopf technique and established a simplified analytical model for the problem, which helped us capture some very important features in the fluid field and deformation of the structure, such as resonance. Sincerely thanks for the support from Dr Luofeng Huang!
