Physical unclonable functions (PUFs) are emerging as an alternative to information security by providing advanced level of cryptographic keys with non-replicable characteristics, yet the conventional PUFs not reconfigurable from ones assigned at manufacturing stage and overall authentication process slows down number entities in dataset or length key increases. Herein, a supersaturated solution-based PUF (S-PUF) is presented that utilizes stochastic crystallization sodium acetate solution...
Abstract Structural coloration is closely related to the progress of innovative optoelectronic applications, but absence direct, on‐demand, and rewritable schemes has impeded advances in relevant area, particularly including development customized, reprogrammable devices. To overcome these limitations, a digital laser micropainting technique, based on controlled thin‐film interference, proposed through direct growth absorbing metal oxide layer metallic reflector solution environment via...
Laser-induced forward transfer (LIFT) and selective laser sintering (SLS) are two distinct processes that can be applied to metal nanoparticle (NP) ink for the fabrication of a conductive layer on various substrates. A pulsed continuous-wave (CW) utilized respectively in conventional LIFT SLS processes; however, this study, CW laser-induced NP is proposed achieve simultaneous wide range polymer At optimum parameters, it was shown high-quality uniform conductor created acceptor substrate...
Poly(dimethylsiloxane) has attracted much attention in soft lithography and also been preferred as a platform for photochemical reaction, thanks to its outstanding characteristics including ease of use, nontoxicity, high optical transmittance. However, the low stiffness PDMS, an obvious advantage lithography, is often treated obstacle conducting precise handling or maintaining structural integrity. For these reasons, Glass-PDMS-Glass structure emerged straightforward alternative....
Selective laser sintering of metal nanoparticle ink is a low-temperature and non-vacuum technique developed for the fabrication patterned layer on arbitrary substrates, but its application to composed large area with small voids very much limited due increase in scanning time proportional pattern density. For facile manufacturing such layer, we introduce micropatterning based laser-induced thermocapillary flow as complementary process previous selective ink. By harnessing shear solvent at...
Selective laser sintering of metal nanoparticle ink is an attractive technology for the creation layers at microscale without any vacuum deposition process, yet its application to elastomer substrates has remained a highly challenging task. To address this issue, we introduced shear-assisted transfer by utilizing difference in thermal expansion coefficients between and target electrode. The was focused scanned across absorbing layer that conformal contact with high coefficient. resultant...
Gold is an essential noble metal for electronics, and its application area increasing continuously through the introduction of gold nanoparticle ink that enables rapid prototyping direct writing electrodes on versatile substrates at a low temperature. However, synthesis nanoparticles has certain limitations involving high cost, long time, large waste material, frequent use chemicals. In this study, we suggest simultaneous laser refining cyanide selective fabrication directly substrate...
Epitaxial growth of inorganic crystals on 2D materials is expected to greatly advance nanodevices and nanocomposites. However, because pristine surfaces are chemically inert, it difficult grow epitaxially materials. Previously, successful results were achieved only by vapor-phase deposition at high temperature, solution-based including spin coating made the epitaxial unaligned, sparse, or nonuniform Here, we show that solvent-controlled can uniformly deposit a dense layer AgCN microwires...
Al-doped ZnO thin films were prepared by ink-jet printing and their electrical thermal properties with different amounts of Al doping sintering atmosphere investigated. The XRD traces show the doped materials did not form additional crystalline phases increasing doping. Electrical conductivity film increased from 4.86 S/cm to 120.94 as 0 wt% 4 wt%. However, decreased 24 W/mK 13 shows higher values sintered in vacuum (120.94 S/cm) compared air (114.1 S/cm).
This study presents a solvent-controlled spin coating method that can uniformly synthesize dense layer of epitaxial AgCN microwires onto various 2D materials. The combination and an aqueous ethanol mixture promotes heterogeneous crystal nucleation on material surfaces, which leads to highly aligned, uniform, growth the unlike previous drop casting methods. Because coated are observable with conventional optical microscopy removable simple wet chemistry, we apply our large-area...
In article number 2006854, Seung Hwan Ko, Sukjoon Hong, and co-workers propose a digital laser micropainting technique, based on controlled thin-film interference, through direct growth of the absorbing metal oxide layer metallic reflector. Specific wavelength-dependent photoresponsivity can be assigned, erased, reassigned to an optoelectronic device by successive application proposed which substantiates its potential for future reprogrammable applications.
