To address this strength-resilience trade-off, we report a sustainable alternative: A wood-derived carbon aerogel that turns ordinary wood into a carbon material with high-temperature thermal insulation capability under inert atmospheres. This is achieved by using a delignified wood carbon sponge scaffold infiltrated with phenolic carbon aerogels of variably controlled particle sizes (tunable via resorcinol/chitosan ratio adjustment). The natural cellulose skeleton provides elastic buckling capacity, while the multisized phenolic fillers reinforce cell walls and inhibit crack propagation, forming a synergistic load-bearing network. The WCS-CA50 sample exhibits a room-temperature thermal conductivity of 0.037 W/(m·K), a thermal conductivity of 0.13 W/(m·K) at 1100°C, and a compressive stress of 0.517 MPa at 50% strain, indicating a balanced combination of thermal insulation and mechanical performance.

In practice, bulk LM is transformed into micro/nano-particles (LMPs) to improve stability and processability for composites. LMPs are typically prepared via shear, ultrasonication, or microfluidics in liquid media, requiring subsequent processing to obtain dry particles. Herein, inspired by friction-induced aggregation during cream application, a dry-state friction strategy is developed for solvent-free fabrication of LMPs. During friction, bulk LM is continuously fragmented, while freshly exposed surfaces rapidly oxidize in air to form robust shells. Unlike conventional liquids, which rapidly coalesce after shear, this structure prevents re-coalescence, yielding stable core-shell LMPs. Particle size can be tuned by adjusting friction parameters, including pressure, speed, and duration, and alkaline surface modification enables control over morphology and oxide shell thickness. The as-prepared LMPs exhibit excellent stability in air and liquid, with no corrosion of metal substrates. Incorporation into a polyvinylpyrrolidone (PVP)-fructose matrix produces a sensing gel with stable electromechanical response, good durability, and degradable and recyclable characteristics.

Early research on the production of pFGPMs has demonstrated that graded architectures can be induced as indirect outcomes of time-evolving temperature, pressure, or concentration fields. Because these gradients emerge from process-driven kinetics, reproducibility and spatiotemporal control remain limited. Fluid templating offers a more direct route: the transient structure of polymerizable/crosslinkable foams or high internal phase emulsions (HIPEs) can be transferred into a solid matrix while controlling compartment size, packing, and film stability during solidification. Microfluidics enhance fluid management by confining interfacial breakup to produce monodisperse bubbles or droplets whose size, volume fraction, and interconnectivity can be tuned independently, transforming liquid templates into programmable solid architectures. This review follows the evolution of microfluidic templating toward its integration with additive manufacturing, with an emphasis on platforms that embed in-line bubble or droplet generation at the printhead.

The balanced reaction pathway favors film densification, more complete grain coalescence, and improved vertical structural uniformity, yielding compact and smooth films with more balanced local bonding.

A mechanistic framework is established around mesophase topology, local chemical environment, and processing-dependent structural persistence, with particular emphasis on distinguishing experimentally demonstrated mechanisms from interpretation based primarily on modeling or indirect correlations. In electrochemical storage, LC architectures regulate ion-pathway connectivity, solvation, water activity, electrodeposition, and interphase evolution. In perovskite and organic photovoltaics, LC additives, interlayers, and elastomeric networks influence defect chemistry, crystallization, molecular packing, energetic losses, and mechanical stability. Dye-sensitized solar cells provide a distinct case in which ordered electrolytes regulate redox-ion transport, whereas smart windows and related adaptive systems exploit LC reorientation, scattering, absorption, and phase transitions to control light and heat. Across these applications, performance is governed by recurring trade-offs among transport, structural fixation, interfacial selectivity, optical loss, and processing tolerance.

This task is technically complex because hydrogen isotopes exhibit nearly identical physicochemical properties making them difficult to separate conventionally. Cryogenic distillation currently serves as the reference technology for isotope separation but suffers from high energy demand, extreme cryogenic operating temperatures, and significant tritium hold-up.
