, 2021 We establish sufficient conditions for a uniform Lp⋆(Ω) bound to imply a uniform L∞(Ω) bound for positive weak solutions of subcritical p-Laplacian equations. We also provide an equivalent result for sequences of boundary-value problems. As consequences,

Carbon Energy, EarlyView.Integrating renewable energy with electrochemical conversion and storage is crucial for sustainable energy solutions. Nitrogen‐doped biomass‐derived carbon materials have emerged as effective catalysts for key reactions such as ORR, HER, and CO2RR. This review explores their synthesis, functionalization, characterization, and catalytic applications ...

ChemFoodChem, EarlyView.Agro‐industrial residues contain dietary fiber and phenolics, but coexistence alone does not establish a phenolic‐bound ingredient. Processing‐dependent identity is verified through fraction‐specific analysis and common‐basis mass balance. Food‐grade translation requires final‐product performance, sensory acceptance, safety, and claim‐matched ...

Subcritical and supercritical fluid extraction of heavy metals from sand and sewage sludge [PDF]
Journal of the Serbian Chemical Society, 2013 Demetalization of Pb, Ni, Zn, Cu and Cr heavy metal ions from sea sand and real samples of sewage sludge by subcritical water and supercritical carbon dioxide was investigated.

Subcritical Equilibria in Taylor-Couette Flow [PDF]
Physical Review Letters, 2014 Nonlinear equilibrium states characterized by strongly localized vortex pairs are calculated in the linearly stable parameter region of counterrotating Taylor-Couette flow. These subcritical states are rotating waves whose region of existence is consistent with the critical threshold for relaminarization observed in experiments.

Sequential Pressurized Liquid Extraction of Food Matrices: Fractionation, Selectivity, and Scale‐Up
ChemFoodChem, EarlyView.Sequential pressurized liquid extraction separates food‐processing side streams into chemically distinct fractions by changing solvent polarity and operating conditions across stages. Lipophilic and phenolic compounds are recovered selectively, while co‐extraction is reduced.

Leaching of coals with subcritical water
International Journal of Coal Preparation and Utilization, 2019 The effects of subcritical water and organic acid additives on the leaching of three low-rank Turkish coals, Can Tuncbilek, and Soma which have high ash and moderate sulfur contents were investigat...

Two-equation model of mean flow resonances in subcritical flow systems [PDF]
, 2008 [Abstract]: Amplitude equations of Landau type, which describe the dynamics ofthe most amplified periodic disturbance waves in slightly supercritical flow systems, have been known to form reliable and sufficiently accurate low-dimensional models capable ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.
