There has been a compelling demand of fabricating high-resolution complex three-dimensional (3D) structures in nanotechnology. While two-photon lithography (TPL) largely satisfies the need since its introduction, low writing speed and high cost make it impractical for many large-scale applications. We report digital holography-based TPL platform that realizes parallel printing with up to 2000 individually programmable laser foci fabricate 3D 90 nm resolution. This effectively improves...
A major challenge in nanotechnology is the fabrication of complex three-dimensional (3D) structures with desired materials. We present a strategy for fabricating arbitrary 3D nanostructures library materials including metals, metal alloys, 2D materials, oxides, diamond, upconversion semiconductors, polymers, biomaterials, molecular crystals, and inks. Specifically, hydrogels patterned by femtosecond light sheets are used as templates that allow direct assembly to form designed...
Abstract The localized surface plasmon resonance (LSPR) of plasmonic nanomaterials is highly dependent on their structures. Going beyond simple shape and size, further structural diversification demands the growth non‐wetting domains. Now, two new dimensions synthetic controls in Au‐on‐Au homometallic nanohybrids are presented: number Au islands emerging shapes. By controlling interfacial energy kinetics, a series Au‐on‐AuNR hybrid structures successfully obtained, with newly grown domains...
Abstract Hollow nanostructures are widely used in chemistry, materials, bioscience, and medicine, but their fabrication remains a great challenge. In particular, there is no effective strategy for assembly interconnection. We bring pottery, the oldest simplest method of fabricating hollow containers, into nanoscale. By exploiting liquid nature xylene template, fullerene tailored shapes, such as bowls, bottles, cucurbits, readily synthesized. The templates permit stepwise versatile...

The steam-assisted gravity drainage (SAGD) process is effective to improve oil recovery performance, but it also promotes the aquathermolysis reaction of heavy under high-temperature reservoir environment. In present work, a geological model considering core-catalyzed was established and used simulate mining in SAGD process. Results showed that gas generation from enhanced by core. Then, production catalyzed core embedded into model. simulation results show main areas occurred at top liquid...
Spin polarization modulation in ferromagnetic materials has become an effective way to promote the electrocatalytic oxygen evolution reaction (OER). Herein, reveal coercivity-related OER performance, single-domain CoFe2O4 (CFO) nanocrystals with different coercivities are synthesized and subjected under situ tunable magnetic field. As more ordered spin state of CFO a higher coercivity can afford facilitated electron transfer process, field-assisted activity be improved increase coercivity....
Abstract By manipulating the nucleation and growth of solid materials, synthesis various sophisticated nanostructures has been achieved. Similar methodology, if applied to liquids, could enable mass‐production control ultra‐small droplets at scale nanoparticles (10 −18 L or below). It would be highly desirable since play a fundamental role in numerous applications. Here we present general strategy synthesize manipulate nanoscale droplets, similar what done classic solution‐synthesis. was...
Controlled docking, merging, and welding of hollow structures at the nanoscale are essential in constructing sophisticated systems ways similar to plumbing biosystems. To this end, regioselectivity is an important milestone demanding new tools. We bring steric effect, a powerful regioselective method organic reactions, nanoscale. By tuning exposed liquid area Janus nanobowls, sterics merging m-xylene template can be precisely modulated, giving high-purity dimers (93.6%) tetramers (80.6%) one...
We report a three-step tandem polymer self-assembly, from PS-b-P4VP macromolecules to vesicles, vesicles chains, and chains stacked bowls. Once aggregated, the soft hydrogen-bonded interface favor gradual increase of contact area, thus promoting concerted optimization toward The continual structural modification opens new route for exploring sophisticated synthetic control complex shapes.
Direct laser writing (DLW) has been widely used in a variety of engineering and research applications. However, the fabrication complex robust three-dimensional (3D) structures at submicron-level resolution by DLW is still largely limited focus quality, i.e., point spread function (PSF), dose, precision mechanical scanners, printing trajectory. In this work, we present two-photon polymerization (TPP)-based system based on digital micromirror device (DMD) binary holography to realize...
