Online verification of adjustable robust optimization for electric hydrogen integrated energy systems with comprehensive demand response

International Journal of Electrical Power & Energy Systems
Traditional energy systems are gradually transitioning to new energy systems dominated by clean sources such as wind, solar, and hydrogen. As the penetration of renewable energy increases, the high uncertainty in their output presents significant ...

The Influence of Graphene Curvature on Hydrogen Adsorption: Towards Hydrogen Storage Devices

, 2013
The ability of atomic hydrogen to chemisorb on graphene makes the latter a promising material for hydrogen storage. Based on scanning tunneling microscopy techniques, we report on site-selective adsorption of atomic hydrogen on convexly curved regions of

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Insights into the co-combustion attributes and mutual effects of high-alkali lignite and flotation carbon-rich fractions from coal gasification fine slag

Results in Engineering
The reutilization of waste coal gasification fine slag (GFS) as an energy source through co-combustion technology has been demonstrated to be a more economically and environmentally viable solution.

Detection of Pristine Gas Two Billion Years after the Big Bang [PDF]

, 2011
In the current cosmological model, only the three lightest elements were created in the first few minutes after the Big Bang; all other elements were produced later in stars.

Dual PI3K/AKT and CDK4/6 inhibition reveals selective sensitivity in an SHH medulloblastoma stem cell model

Molecular Oncology, EarlyView.
Targeted therapy was evaluated in SHH medulloblastoma using neuroepithelial stem cell (NES) and tumor‐derived NES‐like (tNES) models in 2D monolayers and 3D spheroids. PI3K, AKT, and CDK4/6 inhibitors had minimal effects in NES but markedly reduced viability and growth and induced apoptosis in tNES cells, revealing distinct therapeutic vulnerabilities.

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Compositional simulation of the synergistic impact of impurities and geochemical reactions on the efficiency of impure CO₂ sequestration at a Korean CCS site

Results in Engineering
Carbon capture and storage involves CO2 injection into geological structures to mitigate industrial CO2 emissions. CO2 capture processing can lead to inclusion of impurities such as H2S and CH4, which alter the properties of CO2, influencing geochemical ...
