This review systematically summarizesrecent progress in monolithically integrated solar energy harvestingand storage systems, with particular emphasis on structural architectures,photovoltaic configurations, electrode/electrolyte engineering, andmultifunctional device designs. The advantages and limitations oftwo-electrode, three-electrode, and shared-substrate configurationsare critically compared in terms of internal resistance, power matching,fabrication complexity, mechanical flexibility, and overall energyconversion-storage efficiency. Recent advances in rigid, flexible,and fibrous integrated systems based on silicon, dye-sensitized, perovskite,organic, and quantum-dot solar cells are comprehensively discussed,alongside emerging developments in photorechargeable supercapacitors,electrochromic systems, and multifunctional photovoltaic–triboelectrichybrid devices. Particular attention is given to the roles of advancedmaterials, including graphene, carbon nanotubes, MXenes, conductivepolymers, and other low-dimensional materials, in enhancing electrochemicalperformance, flexibility, and device stability. Current challengesassociated with electrolyte compatibility, device mismatch, mechanicaldurability, long-term cycling stability, scalability, and performancestandardization are further analyzed.

Carbon dioxide sequestration is chosenas a critical technology for reducing CO₂ emissions intothe atmosphere. Significant progress has already been made in CO₂ sequestration, with numerous pilot projects and field-scaleoperations underway. The trapping mechanisms involved in deep salineaquifers help in long-term storage. However, the studies on the coupledeffects of flow and various trapping mechanisms are limited. Therefore,in the current work, the coupled two-phase flow and density-drivenconvective dissolution were studied using numerical simulations inCOMSOL Multiphysics. The model is assumed to be isothermal and homogeneous.The primary results showed that pressure and saturation changes duringinjection and after shutdown have a significant impact on convectivedissolution, which differs from single-phase models. In the mathematicalframework, a solubility model is implemented to understand the effectof equilibrium concentration on convective dissolution quantitatively,followed by a sensitivity analysis conducted by varying the compositionof brine, permeability, and Rayleigh number. From the brine compositionsensitivity study, brine density, viscosity, and equilibrium concentrationvariation with brine composition were identified as crucial for convectivedissolution as well as CO₂ plume migration. Later, permeabilityvariation showed that convective dissolution accelerated with an increasein permeability. Then, the combination of fluid and rock propertiesused in the Rayleigh number investigation showed a significant impacton saturation and pressure changes in the aquifer.

AOS–LBshowed a stronger tendency toward bulk micellization and drainageresistance, whereas SDBS–LB exhibited more favorable interfacialcharacteristics, bulk viscoelasticity, and the highest overall foamstability. At 70 °C, SDBS–LB maintained a foam half-lifeof 65 min and reduced proppant settling velocity by approximately46% relative to AOS. The combined results revealed distinct but complementarystabilization pathways, with AOS–LB dominated by bulk structuralorganization and SDBS–LB benefiting from favorable interfacialcharacteristics and bulk viscoelasticity. The novelty of this worklies in establishing an integrated framework that relates interfacialcharacteristics, bulk rheology, drainage, bubble morphology, and proppanttransport to the temperature-dependent stability of anionic–zwitterionicfoam systems.

Higher reservoir permeability results in greater gas and waterproduction, a higher water–gas ratio, and higher sand production.In contrast, a higher initial water saturation of the SGL reducesgas production but increases water production and water–gasratio while suppressing sand production. A larger overall pressuredrawdown enhances gas and water productivity but aggravates sand production.A smaller single-step pressure reduction causes a more pronounceddelay in productivity release and induces alternating expansion–contractionfluctuations of the sand production zone.

Hydroprocessed esters and fatty acids syntheticparaffinic kerosene (HEFA-SPK) remains the most commercially deployedASTM-certified sustainable aviation fuel (SAF) pathway, reducing life-cyclegreenhouse gas (GHG) emissions by approximately 55–92% on aCO₂-equivalent basis relative to conventional Jet A-1,with variations driven by feedstock type, hydrogen source, and life-cycleassessment methodology and assumptions. However, large-scale HEFA-SAFdeployment remains constrained by catalyst deactivation, limited jet-rangeselectivity, high hydrogen demand, and volatile lipid feedstock costs.Unlike previous HEFA-SAF reviews that evaluated catalyst development,process conversion, and economic assessment in isolation, this workprovides a multiscale integration framework that systematically linksmolecular-level catalyst mechanisms with techno-economic performanceand machine learning (ML) optimization. Within this framework, catalystselectivity among the “hydrodeoxygenation” (HDO), “decarboxylation”(DCX), and “decarbonylation” (DCN) pathways is directlyconnected to hydrogen consumption and the feedstock-dependent minimumjet fuel selling price (MJFSP), whereas “hydrocracking”and “hydroisomerization” efficiency are linked to hydrogencosts and process configurations. Drawing on the literature from 2017to June 2026, this review critically evaluates the opportunities andlimitations of ML across the HEFA-SAF value chain, emphasizing thatML-guided catalyst discovery requires rigorous experimental validationbefore industrial implementation. To address data fragmentation acrossthe published literature, a standardized, integrated HEFA data setframework─combining catalyst-level descriptors, process-levelparameters, techno-economic indicators and a 2025–2030 researchroadmap─is introduced as the primary contribution. The roadmapidentifies four critical priorities: extending catalyst lifetime underrealistic feeds, reducing external hydrogen dependence, establishingreliable low-cost feedstock supply chains, and developing validateddata sets for ML-driven optimization.
