in electronics, [1] pharmaceuticals and healthcare, [2] energy harvesting and storage, [3][4][5][6] sensing, [7] coating, [8] structural application, [9][10][11] and many more. Nanofabrication techniques are generally divided into top-down and bottom-up categories. [12] Photolithography, [13] including UV, [14] focused ion beam, [15] electron-beam [16] and X-ray lithography, [17] FIB milling, [18] nanoimprint lithography [19] (stamping), dip-pen nanolithography, [20] and scanning probe lithography [21] are among the primary topdown nanofabrication techniques. These methods are specifically used for planar structures (e.g., chip-making) with micro/ nanoscale resolution features, depending on the wavelength of the source beam, and are not suitable for complicated 3D geometries. Bottom-up nanofabrication techniques are based on the self-assembly of unit compounds that use physical and chemical forces available to form larger structures. [22] Atomic layer deposition, [23] chemical [24,25] and physical vapor deposition, [26] sol-gel, [27] and DNA scaffolding [28] are among the most prominent bottomup nanofabrication methods. Self-assembly as the backbone of bottom-up fabrication techniques is the result of random collision of components within a solvent that reach an equilibrium state, either static or dynamic. [29] The resulting formation translates into deposited nanostructures through evaporation of particle-laden droplets in manufacturing techniques such as inkjet printing/direct writing, additive manufacturing, and various coating systems. [30][31][32] As the water evaporates, nanoparticles (NP) accumulate on the substrate in a form between a coffee ring shape (CRE), where the majority of the NPs gather on the periphery of the droplet, or in a disk shape (DS), where the NPs scatter across the base of the droplet. [33,34] Uniform particle dispersions, which correspond to the DS formation, are essential to scientific and industrial efforts. [35][36][37] However, their formation is impeded by the constant presence of outward radial Capillary effect driving suspended particles to the contact line, which is a result of the fluid stretching over the fixed contact line as the evaporation takes place. [38,39] One approach for amending CRE is implementing Marangoni flow, which is the result of surface tension gradient caused by either thermal effects or nonhomogeneous changes in composition, the latter of which happens within drying droplets with certain surfactants. [40][41][42][43] As a result, the exact shape of the deposits varies Achieving desired performance from self-assembly of nanoparticles (NPs) is challenging due to the stochastic nature of interactions among the constituent building blocks. Self-assembly of nano-colloids through evaporation of particle-laden droplets can be exploited to fabricate tailored nanostructures that add functionality and engineer the properties of manufactured components. The particle-particle and particle-solvent interactions, and delicate force balance among them are the main factor...

Multifunctionality through Embedding Patterned Nanostructures in High‐Performance Composites

Despite being a pillar of high‐performance materials in industry, manufacturing carbon fiber composites with simultaneously enhanced multifunctionality and structural properties has remained elusive due to the lack of practical bottom‐up approaches with control over nanoscale interactions. Guided by the droplet's internal currents and amphiphilicity of nanomaterials, herein, a programmable spray coating is introduced for the deposition of multiple nanomaterials with tailorable patterns in composite. It is shown that such patterns regulate the formation of interfaces, damage containment, and electrical‐thermal conductivity of the composites, which is absent in conventional manufacturing that primarily rely on incorporating nanomaterials to achieve specific functionalities. Molecular dynamics simulations show that increasing the hydrophilicity of the hybrid nanomaterials, which is synchronous with shifting patterns from disk to ring, improves the interactions between the carbon surfaces and epoxy at the interfaces,manifested in enhanced interlaminar and flexural performance. Transitioning from ring to disk creates a larger interconnected network leading to improved thermal and electrical properties without penalty in mechanical properties. This novel approach introduces a new design , where the mechanical and multifunctional performance is controlled by the shape of the deposited patterns, thus eliminating the trade‐off between properties that are considered paradoxical in today's manufacturing of hierarchical composites.

“…It has been reported that some polar components of bitumen help enhance the adhesive forces due to their affinity toward mineral aggregate surfaces . An example of this is the affinity of asphaltene molecules with dense aromatic cores and polar nitrogen and oxygen atoms toward siliceous aggregates. ,, Asphaltene and resin molecules with a high number of oxygenated sites in their molecular structures form multiple hydrogen bonds with a siliceous surface . However, an increase in polar functional groups of bitumen does not always boost the adhesive strength.…”

Premature failure at the bitumen−aggregate interface is attributed to the surface chemistry of stone aggregates. Bitumen modifiers with high affinity toward aggregates are often used to change the surface chemistry of aggregates, which in turn changes the type and strength of stones' interactions with bitumen.Here, the mechanisms of action and the effects of an organosilane and bio-oil separately on the bitumen−aggregate interface, including their binding to aggregates from one side and to bitumen from the other side, were studied and compared. The binding of bio-oils and organosilanes to aggregates is well documented, as well as their efficacy as anti-stripping agents, but their binding to bitumen is not well understood. Using glass beads as a surrogate for siliceous stones, we obtained laboratory measurements of interfacial strength as measured by resistance to shear forces at the interface of bitumen and silica. Our laboratory measurements showed the highest value for the bitumen modified with bio-oil, followed by the control bitumen with no modification, and the lowest value for the bitumen modified with organosilane. Our molecular modeling calculations showed that the adhesion of bitumen molecules to silica coated with bio-oil was notably stronger (up to 72%) than the adhesion of bitumen molecules to silica coated with organosilane. The higher interfacial strength observed for bitumen with bio-oil is attributed to bio-oil having various functional groups with the ability to form hydrogen bonds and π−π interactions with the aromatic and polar components of bitumen. The study outcomes highlight the importance of modifiers' ability to strongly interact with both aggregates and bitumen. The bio-oil modifier introduced in this work can form a robust bridge between bitumen and siliceous aggregates to improve the adhesive properties, enhancing the sustainability and durability of bituminous composites.
