The next step in nanotechnology is to establish a methodology assemble new functional materials based on the knowledge of nanotechnology. This task undertaken by nanoarchitectonics. In nanoarchitectonics, we architect material systems from nanounits such as atoms, molecules, and nanomaterials. terms hierarchy structure harmonization function, created nanoarchitectonics has similar characteristics organization biosystems. Looking at actual biofunctional systems, dynamic properties interfacial environments are key. other words, interfaces important for production bio-like highly systems. this review paper, will be discussed, looking recent typical examples. particular, basic topics “molecular manipulation, arrangement, assembly” “material production” discussed first two sections. Then, following section, “fullerene assembly: zero-dimensional unit advanced materials”, discuss how various structures can very nanounit, fullerene. above examples demonstrate versatile possibilities architectonics interfaces. last these tendencies summarized, future directions discussed.

A complete model for estimating the electric conductivity of combustion product gases, with added cesium (Cs) or potassium (K) vapor ionization, is presented. Neutral carrier gases serve as bulk fluid that carries seed material, well electrons generated by partial thermal (equilibrium) ionization alkali metal. The accounts electron-neutral scattering, electron-ion and electron-electron scattering. tested through comparison published data. aimed at being utilized plasma within magnetohydrodynamic (MHD) channels, where direct power extraction from passing electrically conducting gas enables generation. then used to estimate seeded under three selected fuels, namely: hydrogen (H2), methane (CH4), carbon (C). For each these two options oxidizer were applied, air (21 % molecular oxygen, 79 nitrogen mole), pure oxygen (oxy-combustion). Two types seeds (with 1 mole fraction, based on composition before ionization) also applied six combinations (fuel-oxidizer), leading a total 12 different MHD cases. cases, was computed range temperatures 2000 K 3000 K. smallest estimated 0.35 S/m oxy-hydrogen K, seeding. largest 180.30 oxy-carbon At replacing causes gain in multiplicative factor about 3.6 regardless fuel oxidizer.

Featuring low cost, melting points, excellent biocompatibility, outstanding electrical conductivity, and mechanical properties, gallium-based liquid metals (LMs) have become a promising class of materials to fabricate flexible healthcare sensors. However, the extremely high surface tension hinders their manipulation cooperation with substrates. To address this problem, inspiration nanomaterials has been adopted mold LMs into LM nanoparticles (LMNPs) expanded advantages. The transformability LMNPs endows them functionalities for sensors in multiple dimensions, such as intelligent response specific molecules or strains, various morphologies, integration high-resolution circuits, conductive elastomers. This review aims summarize superior properties LMs, LMNPs, correlated advantages sensor performance. Multidimensional functional sensing forms consisting corresponding applications will be presented. In end, existing challenges prospects processing application also discussed.

Abstract The characteristic feature of a biofunctional system is that components with various functions work together. These multi-components are not simply mixed together, but rationally arranged. fundamental technologies to do this in an artificial include the synthetic chemistry substances make component unit, science and techniques for assembling them, technology analyzing their nanoostructures. A new concept, nanoarchitectonics, can play role. Nanoarchitectonics post-nanotechnology concept involves building functional materials reflect nanostructures. In particular, approach combining multiple types create composite area where nanoarchitectonics be powerful tool. This review summarizes such examples related studies. presented areas catalyst & photocatalyst, energy, sensing environment, bio medical, other applications illustrate potential wide range applications. order show stages development, only state-of-the-art, also those successful developments existing research. Finally, summary brief discussion future challenges will given. applicable all aims establish ultimate methodology science.

It has become clear that superior material functions are derived from precisely controlled nanostructures. This been greatly accelerated by the development of nanotechnology. The next step is to assemble materials with knowledge their nano-level structures. task assigned post-nanotechnology concept nanoarchitectonics. However, nanoarchitectonics, which creates intricate three-dimensional functional structures, not always easy. Two-dimensional nanoarchitectonics based on reactions and arrangements at surface may be an easier target tackle. A better methodology would define a two-dimensional structure then develop it into function. According these backgrounds, this review paper organized as follows. introduction followed summary three issues; (i) 2D 3D dynamic control: liquid crystal commanded surface, (ii) rational construction: metal-organic framework (MOF) covalent organic (COF); (iii) amplification: cells regulated surface. In addition, summarizes important aspects ultimate perspective. goal establish integrated creation reconsidering various reported cases viewpoint where can regarded method for everything in science.

Flexible conductive sensor materials have received great attention for their sensitive electrical response to external conditions and promising applications in flexible wearable robotic applications. In this work, a highly stretchable force temperature material with sandwich structure was prepared from the polydimethylsiloxane (PDMS) liquid metal (LM) gallium-indium-tin alloy (GaInSn). The (PDMS + PDMS/GaInSn PDMS) proven prevent "leakage" of LM. preparation method sensing simple time-saving (less than 1.5 h) can be used industrial production. performance analysis results confirmed that resistance (R) force, such as repeated stretching, compressing, bending, impacting. ΔR/R changed periodically stably when GaInSn/Part A ≥ 0.4, cyclic tensile strain ≤ 50%, rate 2.5 mm/min. R also responsive temperature, hot air nitrogen. conclusion, work provides preparing structure, which without leaking LM, it produced different types signals under deformations temperatures.
