While SNaP utilizes the same self‐assembly principles as one‐step Flash NanoPrecipitation, SNaP is a two‐step assembly process in which the particle core formation is initiated during a first mixing step followed by particle stabilization in a second mixing step. Current SNaP experimental set‐ups use commercial millifluidic mixers connected in series, which have several limitations, including the inability to access short inter‐mixer delay times (Td). A robust, 3D‐printed, modular mixer design that enables access to short Td's (〈 25 ms) not previously accessible is reported. For the first time, it is demonstrated that decoupling the assembly steps improves control over particle size, expanding the attainable size range to include both nanoparticles and microparticles. It is empirically proven that inter‐mixer Td is a key parameter for particle size control and that particle size scales with Td in agreement with Smoluchowski's model of diffusion‐limited growth. The formation of particles ranging in size from 160 nm to 1.2 µm is shown. Finally, the applicability of the new mixers is established by encapsulating fluorophores and therapeutics into particles for the first time via SNaP.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike traditional color rendering methods, they are realized mainly through micro/nanostructures that interfere, diffract, scatter light, and exhibit long‐life and environmental‐friendly color effects. In nature, a few organisms use their color‐changing system to transmit information, such as courtship, warning, or disguise. Meanwhile, some natural inorganic minerals can also exhibit structural colors. Learning from nature, scientists have achieved large‐scale structural color design and manufacturing technology for artificial photonic crystals. Photonic crystals have a unique microstructure that forms a band gap under the action of the periodic potential field, consequently causing Bragg scattering due to the periodic arrangement of different refractive index media within them. Because of the apparent photonic band gap and the ability to form local photons at crystal defects, photonic crystals have been extensively studied in recent years and have broad application prospects in photonic fibers, optical computers, chips, and other fields. In this review, the research, properties, and applications of photonic crystals in recent years are presented, as well as insight into the future developments of photonic crystals.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141937522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to solve the challenges of TENG in sensing signal processing, such as signal noise and nonlinear relations, Machine Learning (ML), which is an efficient and mature data processing tool, is widely applied for efficiently processing the large and complex output signal data generated by TENG intelligent sensing system. This review summarizes and analyzes the adaptation of different algorithms in TENG and their advantages and disadvantages at the beginning, which provides a reference for the selection of algorithms for TENG.

In addition, robust, reproducible, and accurate temperature measurements are essential in these areas. The ultra-wide band gap semiconductor material Ga2O3 is a suitable host for optical sensing in harsh environments due to its high stability. In this work, the thermometric operation of Ga2O3:Cr-based microcavities are evaluated. They are designed as follows: Ga2O3:Cr microwires are encapsulated in multilayers fabricated by atomic layer deposition (ALD), which act as both Bragg reflectors and protective layers for the thermometric sensor. Prior to the ALD encapsulation step, focused ion beam carved trenches at the microwire ends are necessary to accommodate the multilayer coating. The structural and optical properties of the devices are assessed experimentally, analytically and by simulations. The developed microthermometers can be easily calibrated using a cubic polynomial for the temperature-dependent resonant peak position shift. A better than 0.5 °C temperature resolution and accuracy for temperatures above −80 °C is demonstrated. Additionally, the devices show robustness against excitation laser densities of at least 34 W mm−2, can operate at temperatures up to 600 °C and remain functional in liquids.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141881302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, challenges persist in terms of mechanical performance and durability. This study focuses on the development of organic–inorganic hybrid nanoparticles for superhydrophilic coatings that exhibit exceptional thermomechanical stability and long-term durability. Employing green chemistry, polyethylene glycols (PEGs) are grafted onto silica nanoparticles, controlling the PEG molecular weight from 200 to 1000 to systematically investigate its impact on coating characteristics. Additionally, the intriguing phenomenon of phase separation facilitated by a polyurethane binder and its effects on both morphology and hydrophilicity is investigated. All hybrid coatings consistently exhibit remarkable superhydrophilicity, with contact angles consistently below 10°, the lowest being 1.4°. Longer PEG chains played a pivotal role in enhancing the thermal stability of the grafted PEG shell within the hybrid nanoparticles, achieving a maximum enhancement in decomposition temperature of 150 °C. Furthermore, the PEG shell substantially improves strain durability, with SiO2-PEG 1000–50% exhibiting outstanding transmittance retention of 100% without any cracks even under a 100% tensile strain. SiO2-PEG 200 emerged as the champion in maintaining superhydrophilicity throughout a 20-day long-term durability assessment. Moreover, the research has unveiled the intricate degradation mechanism responsible for the decline in hydrophilicity in these hybrid coatings.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional software-based encryption schemes are vulnerable to advanced attacks based on machine learning or quantum computing, leading to the exploration of hardware-based solutions. This study proposes a novel in-sensor encryption technique using a perovskite photodetectors (PDs) array to integrate image acquisition and encryption functions within a single hardware platform. The technique exploits the inherent physical disorder and randomness of perovskite PDs to provide an optimal source of entropy for the generation of cryptographic keys. The MAPbI3 perovskite PDs array is fabricated by a convenient method and passivated by thioacetamide (TAA) to improve the performance in photoresponsivity, response time, spectra response, and stability, enabling sensitive imaging and reliable key generation. The improved perovskite PDs array exhibits remarkable optoelectronic properties and stability, highlighting its potential for in-sensor encryption and the creation of trustworthy hardware security systems for imaging terminals.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article reports a technique, microfluidic directed material patterning, which combines soft microfluidic stamps and low-temperature solution-phase deposition to generate multi-material circuits on flexible, non-planar polymeric supports. Specifically, metallic and semiconductive traces are combined on commodity plastic films to yield functional photosensitive circuits that can be used in the spectrophotometric detection and concentration measurement of microdroplets on 3D “e-plates.” The photoresistive material cadmium sulfide is used in these circuits because it is suitable for visible light detection and it can be deposited directly from aqueous solutions following established bath deposition procedures. This method can produce colorimetric devices capable of quantifying micromolar concentrations of Allura Red in microdroplets of Kool-Aid. This technique presents the opportunity for producing single-use or low-use disposable/recyclable devices for flexible 3D sensors and detectors following a convenient, low-waste fabrication scheme. The general capabilities of this approach, in terms of substrate geometry and device layout (e.g., the number, area, and pattern of photoresistive elements), can be applied to the design and manufacture of more intricate, multiplexed devices supportive of advanced and/or specialized functions that go beyond those reported in this initial demonstration.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent advances have involved research on artificial synapses based on organic electrochemical transistors (OECTs), emphasizing low power consumption and rapid response times. A notable challenge arises when the gate voltage is removed, causing doped ions to return quickly to the electrolyte. A simple yet efficient approach is used to solve this problem: forming a microporous active layer using a phase separation method. This technique can maximize the contact area between the electrolyte and the active layer, enhancing ion doping/de-doping in OECTs. Improvements in the product of hole mobility and volumetric capacitance is achieved. The electrostatic coupling effect and electrochemical doping in synaptic OECTs occur better than in the pristine active layer, yielding enhanced performance with higher short-term and long-term synaptic plasticity, compared to pristine OECTs. Moreover, improved ambipolar characteristics is shown by n-dopant injection. This paper reports a way to improve performance by simply modifying the surface shape of the active layer using the phase separation, contributing to advancements in artificial synapses for neural networks.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, imprinting has limited feasibility in realizing complex microstructures due to difficulties arising from the inherent limitations in the demolding process. Herein, a facile method is demonstrated for fabricating closed-loop reentrant topographies with microscale meshes through a combination of imprint lithography and shape memory polymer (SMP). The mesh structure imprinted onto the pre-pressed SMP pillar array can be elevated by utilizing the form-switchable property of SMP to fabricate suspended micromesh. Suspended micromesh is fully supported by restored SMP micropillar array, exhibiting a closed-loop shape that cannot be achieved with conventional imprint lithographic methods. Also, by the nature of reentrant geometry, liquid-repellency can be realized even for liquids with a lower surface tension than water, offering numerous applications in self-cleaning, droplet manipulation, and antifouling. Various liquid-repellent performances of the fabricated suspended micromesh are investigated and compared to the theoretical expectations for a non-wetting structure, confirming the successful establishment of reentrant topography in the fabricated structures. The proposed lithographic technique can be broadly utilized not only for liquid-repellent surfaces but also for the fabrication of various functional structures.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141868409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
