substratesconveys

Substratesconveys is a term used in materials and chemical engineering to describe the strategies and mechanisms by which substrate molecules are transported to a reaction interface. The term combines substrate with conveys to denote movement toward a target site. In practice, substratesconveys encompasses both the physical transport of substrates and the design of materials that facilitate efficient conveyance to catalytic or sensing surfaces.

Mechanisms include convective flow in microchannels, diffusion through porous supports, electrophoretic or electroosmotic transport, capillary action, and surface-guided conveyance along structured channels. Design aims include maximizing delivery rate to active sites while minimizing loss, preventing fouling, and maintaining selectivity.

Applications span heterogeneous catalysis in fixed-bed or microreactor systems, enzymatic reactors, biosensors and lab-on-a-chip devices, and environmental remediation where substrates must reach reactive sites within porous media. Study methods involve tracer experiments, spectroscopy, fluorescence tagging, and computational fluid dynamics or pore-scale modeling to quantify substrate flux, along with dimensionless numbers such as Peclet and Damkohler to relate transport and kinetics.

In design practice, substratesconveys informs the choice of reactor geometry, surface functionalization, pore structure, and driving forces (pressure, electric field, or chemical potential) to optimize substrate delivery. Some analysts note that the term is not universally adopted and that conventional language uses mass transfer, transport phenomena, or substrate delivery rather than substratesconveys; its usage is primarily in niche or speculative discussions.
