Published: April 2023

AbstractIn this work, a simple anti‐fingerprint strategy (reduced ≈40–60%) to rearrange fingerprint droplets by patterned micro/nano‐pore/spoons texture, air cushion and low surface energy is reported. Superior to previous precise and complex preparation methods, the micro/nano‐texture are fabricated through conventional process of spray and dip. The pore and spoon can be freely switched by changing the process. The number (N) and size (r) of pores and spoons are controlled intelligently by solvent volatilization and interfacial tension ( and γFP/PU − Solvent), the key for pore/spoon's forming and expanding. A physical model of interface intelligent controlling the micro/nano‐pore/spoon surface texture induced by “Vacancy‐Capture” is proposed. The description is being reported, for the first time, to the knowledge, expecting to make it possible to prepare anti‐fingerprint engineering materials with newly potential industrial applications on optical device for large‐scale in the future.

Published: April 2023

AbstractSelf‐healable degradable networks encounter a growing popularity for biomedical applications due to their ability to recover their properties after damage. Self‐healable hydrogels dominate with applications in tissue engineering and drug delivery. On the opposite and despite their potential for medical devices, self‐healable elastomers remain scarce, especially if they must be compatible with fused deposition modeling (FDM) 3D‐printing and self‐heal at physiological temperature under a hydrated state. These unmet challenges are addressed in this work with degradable elastomeric networks based on dynamic imine bonds prepared from multi(aldehyde) and multi(amine) hydrophobic PEG‐PLA star‐shaped copolymers. The star topology of these copolymers is the key feature of the strategy as it allows the design of multifunctional high molecular weights pre‐polymers that ensure an efficient dynamic chemical crosslinking while guaranteeing access to the FDM process generally restricted to thermoplastics. The proposed elastomeric networks combine high self‐healing efficiencies at 37 °C (>97%) with mechanical properties compatible with soft tissues and a linear degradation profile. Their FDM processing to produce self‐healable tubular devices is demonstrated. Finally, their cytocompatibility is assessed and confirm their potential as biodegradable elastomeric networks to be used for the design of self‐healable 3D‐printed devices for biomedical applications.

AbstractThe proliferation of disposable, wearable, and implantable printable electronics requires the development of high‐performance biodegradable, and sustainable electronic components. Often green materials don't have the necessary properties for high‐performance electronics, therefore obtaining the ideal properties requires a combination of multiple green materials. A tri‐layer dielectric is reported using poly(lactic acid) (PLA), poly(vinyl alcohol)/cellulose nanocrystals (PVAc), and toluene diisocyanate terminated poly(caprolactone) (TPCL), which is integrated into semiconducting single‐walled carbon nanotube (sc‐SWCNT) based thin film transistors (TFTs) in a top gate bottom contact architecture. The PVA provides a high dielectric constant due to the hydroxy groups, the cellulose is used to optimize the viscosity, the TPCL layer provides a robust hydrophobic surface, and the PLA eliminates the interfacial charge traps present in the PVAc and improves the adhesion between PVAc and the substrate. This leads to a decrease in leakage currents and reduces the polarity at the dielectric/semiconductor interface. The TFTs fabricated using tri‐layer dielectrics led to air‐stable n‐type devices with higher overall performance when compared against the PVAc/TPCL bilayer devices.

Published: April 2023

AbstractIcephobic material is of great importance in power transportation, communication, aerospace, and so on. Bionic lotus superhydrophobic surfaces show good application prospects in anti‐icing by repelling impacting droplets. However, the boundary (criterion) between droplet bounce and deposition on superhydrophobic surface under cold freezing rain is unclear. Here, from the view of statistics, the boundary and internal heat transfer mechanism of the droplet bounce, pinning, and three kinds of deposition including icing at later, early retraction, and spread. are clarified Droplet viscosity increase reduces droplet contact with surface and inhibited splash at high We. Surfaces with temperature above −20.6 °C showed 100% droplet bounce after impact on We = 64.7, and the probability of water adhesion and ice nucleation decreases to ≈0%, resulting in completely anti‐icing. Droplet bounce transition mainly ascribe to the decrease retraction driven force caused by interface freezing and transition temperature increases approximately linearly from −25.9 to −21.1 °C within 21.6 < We < 75.5. Ice nuclei brought by condensation in humid environment (60–100 RH%) further cause droplet eccentric retraction and transition temperature increases to −6 to −10 °C. The fundamental understanding of droplet behaviors on supercooled superhydrophobic surface is beneficial for icephobic surfaces applications.
Strong Impact of Underlayers on the Voltage‐Controlled Magnetic Anisotropy in Interface Engineered Co/MgO Junctions with Heavy Metals

Published: April 2023

AbstractThe voltage‐controlled magnetic anisotropy (VCMA) effect in ferromagnets is of crucial interest for next‐generation non‐volatile magnetic memory technologies since it enables spin manipulation with low power consumption in addition to high‐speed operation and high writing endurance. Although intense efforts are made in the past decade to increase the efficiency of the purely electronic VCMA effect, the physical origin of this phenomenon is still elusive, particularly for interface‐engineered ferromagnetic materials. Here, a pathway is proposed to tune the VCMA effect by exploiting a combination of the insertion of heavy metals and underlayers. Focusing on Co/MgO junction deposited on Os underlayer, a large VCMA effect of −100 fJ V−1 m−1 is demonstrated with Pt insertion, which is ≈50% greater than the case deposited on Pt underlayer. On the other hand, smaller VCMA effect is observed with Ir insertion, and even a positive VCMA effect is observed with Os insertion, which are vastly different from the case deposited on Pt underlayer. The systematic variation of VCMA coefficient depending on the underlayer materials implies the effect of electron depletion from underlayers. The concepts demonstrated here can be applicable for other spintronic materials and may open a way to interfacial spin‐orbit engineering for VCMA effect.
Improving the Stability, Selectivity, and Cell Voltage of a Bipolar Membrane Zero‐Gap Electrolyzer for Low‐Loss CO2 Reduction

Published: April 2023

AbstractElectrolyzers for CO2 reduction containing bipolar membranes (BPM) are promising due to low loss of CO2 as carbonates and low product crossover, but improvements in product selectivity, stability, and cell voltage are required. In particular, direct contact with the acidic cation exchange layer leads to high levels of H2 evolution with many common cathode catalysts. Here, Co phthalocyanine (CoPc) is reported as a suitable catalyst for a zero‐gap BPM device, reaching 53% Faradaic efficiency to CO at 100 mA cm−2 using only pure water and CO2 as the input feeds. It is also shown that the cell voltage can be lowered by constructing a customized BPM using TiO2 water dissociation catalyst, however this is at the cost of decreased selectivity. Switching the pure‐water anolyte to KOH improved both the cell voltage and CO selectivity (62% at 200 mA cm−2), but cation crossover could cause complications. The results demonstrate viable strategies for improving a BPM CO2 electrolyzer toward practical‐scale CO2‐to‐chemicals conversion.

AbstractTo develop a simple and general method for improving the circularly polarized luminescence (CPL) performances of materials is of great significance. In this work, two pairs of CPL‐active homochiral metal–organic frameworks (MOFs) P/M‐Et and P/M‐Et(Cd) with eta topology are reported. In comparison to the reported isomorphic Zn‐imidazolate MOFs P‐Me and M‐Me, both luminescence dissymmetry factor (glum) and photoluminescence quantum yields (ΦPL) of P‐Et and M‐Et are largely improved by simply changing the methyl group to an ethyl group of ligands in P‐Et and M‐Et. Furthermore, the |glum| values are significantly amplified up to 0.015 from 0.0057 by introducing the non‐luminescent halogenated aromatics, while an enhanced fluorescence efficiency is observed simultaneously (from 27.2% to 47.3%). The figure of merit value is about 40 times larger than that of P‐Me and M‐Me. Similarly, the CPL performances of P/M‐Et(Cd) are improved by about five times after encapsulating fluorobenzene molecules. This work represents a new and simple method for developing CPL‐active MOF materials.

AbstractCell‐based therapies comprising the administration of living cells to patients for direct therapeutic activities have experienced remarkable success in the clinic, of which macrophages hold great potential for targeted drug delivery due to their inherent chemotactic mobility and homing ability to tumors with high efficiency. However, such targeted delivery of drugs through cellular systems remains a significant challenge due to the complexity of balancing high drug‐loading with high accumulations in solid tumors. Herein, a tumor‐targeting cellular drug delivery system (MAGN) by surface engineering of tumor‐homing macrophages (Mφs) with biologically responsive nanosponges is reported. The pores of the nanosponges are blocked with iron‐tannic acid complexes that serve as gatekeepers by holding encapsulated drugs until reaching the acidic tumor microenvironment. Molecular dynamics simulations and interfacial force studies are performed to provide mechanistic insights into the “ON‐OFF” gating effect of the polyphenol‐based supramolecular gatekeepers on the nanosponge channels. The cellular chemotaxis of the Mφ carriers enabled efficient tumor‐targeted delivery of drugs and systemic suppression of tumor burden and lung metastases in vivo. The findings suggest that the MAGN platform offers a versatile strategy to efficiently load therapeutic drugs to treat advanced metastatic cancers with a high loading capacity of various therapeutic drugs.

AbstractAlzheimer's disease (AD) is one of the most common neurodegenerative diseases in the elderly population. Despite significant advances in studies of the pathobiology on AD, there is still no effective treatment. Here, an erythrocyte membrane‐camouflaged nanodrug delivery system (TR‐ZRA) modified with transferrin receptor aptamers that can be targeted across the blood–brain barrier to ameliorate AD immune environment is established. Based on metal‐organic framework (Zn‐CA), TR‐ZRA is loaded with CD22shRNA plasmid to silence the abnormally high expression molecule CD22 in aging microglia. Most importantly, TR‐ZRA can enhance the ability of microglia to phagocytose Aβ and alleviate complement activation, which can promote neuronal activity and decrease inflammation level in the AD brain. Moreover, TR‐ZRA is also loaded with Aβ aptamers, which allow rapid and low‐cost monitoring of Aβ plaques in vitro. After treatment with TR‐ZRA, learning, and memory abilities are enhanced in AD mice. In conclusion, the biomimetic delivery nanosystem TR‐ZRA in this study provides a promising strategy and novel immune targets for AD therapy.
Community Psychology's abuse of empowerment to further a white supremacist agenda
Authors: Tran Nellie 
Published: April 2023

AbstractWhen White people are predominantly in power and the discipline has yet to grapple with its own involvement in oppressive and racist ideologies, the concept of empowerment has the potential of being misused, or worse, abused. This is my experience and observation within Community Psychology (CP). In this paper, I interrogate the history of CP, especially the interplay of colonized knowledge production practices and the concept of empowerment, and uncover the use and abuse of well‐meaning community psychological principles by scholars and leaders without the critical racial awareness to apply them to communities to which they do not belong. Lastly, I offer a “slash and burn” approach to starting over.

AbstractHere, we describe the synthetic improvements to the known compound exo‐dicyclopentadiene‐1‐one (exo‐DCPD‐1‐one). Also, an alternative and efficient synthetic approach to exo‐DCPD‐1‐one was developed in a non‐hazardous manner. All the synthesized compounds here are well‐characterized by NMR analysis. The structure and relative stereochemistry of some key intermediates were confirmed by single‐crystal X‐ray diffraction (XRD) studies. Overall, the synthetic studies described here are useful to prepare exo‐DCPD‐1‐one on a multi‐gram scale in a safe manner. The exo‐DCPD‐1‐one is found to be a useful building block to prepare a wide variety of cyclopentanoids.

AbstractIn order to solve the problem of formaldehyde release from the traditional phenolic foam (PF) in the process of coal mine filling and plugging. In this paper, the effect of different factors on the efficiency of formaldehyde trapping agents were studied by adding formaldehyde trapping agents containing amino compounds after PF synthesis. The effect of formaldehyde trapping agents on the performance of resin was investigated. The results showed that the addition of formaldehyde trapping agents could greatly reduce the residual formaldehyde content in phenolic resin. Fourier‐transform infrared spectroscopy (FTIR) data showed that the addition of formaldehyde trapping agent not only successfully prepared PF, but also produced a stable formaldehyde trapping agent product. Compared with the unmodified PF, the pore size and foaming rate of the modified PF decreased in varying degrees, and the foaming temperature also decreased in varying degrees. Among them, urea modified phenolic resin (PUF) had the highest formaldehyde removal efficiency. It had the t lowest heat release during combustion and the foam pore size was large and uniform. In addition, through the application of urea‐modified PF in the goaf return air corner fissure sealing application, it was found that the CO concentration in the goaf maintained at the lowest state of 0.002%. It has reached the national industry standard of polymer gas plugging materials and conforms to the green development concept in the field of coal mine fire prevention.

AbstractPolyhydroxyalkanoates (PHA) are biodegradable linear polyesters mainly produced by bacterial fermentation. These materials are biocompatible, non‐toxic, and have a low environmental impact, making them an excellent alternative to fossil‐based plastics in food packaging. Despite their promising characteristics, PHAs have several disadvantages, such as brittleness, slow nucleation process, thermal instability and consequently poor processability. In this article, poly(3‐hydroxybutyrate‐co‐3‐hexanoate) (PHBHx), a copolymer belonging to the class of PHAs, was blended with polybutylene succinate‐co‐adipate (PBSA) and other process additives in order to improve its properties and realize a hot food container compostable in a domestic environment. The material in the pellet form was produced by reactive extrusion with a corotating twin‐screw extruder. The compound was then processed by cast extrusion and the resulting film was thermoformed into a rectangular container. All the semi‐finished products were characterized thermo‐mechanically and with chemical–physical tests, demonstrating good processability, thermal resistance of 100°C, complete impermeability to oxygen, transmission of light radiation less than 30% and high toughness (<5 kJ/m2). In addition, the morphology of the blende was also investigated by SEM and XRD analysis.

AbstractThis study involves the fabrication of mixed matrix membranes (MMMs) for ultrafiltration, which contained 3‐aminopropyltriethoxysilane modified magnetite iron oxide nanoparticles (A‐Fe3O4 NPs), through a modified phase inversion technique. The physiochemical properties and surface morphologies of both the as‐synthesized A‐Fe3O4 NPs and fabricated MMMs were examined using advanced characterization techniques. The quasi‐spherical A‐Fe3O4 NPs had an average particle size of 12 nm and a Brunauer–Emmett–Teller surface area of 131.38 m2/g. Analysis by Fourier transform infrared and Raman spectroscopy confirmed the presence of NH2 and OH functional groups grafted onto the Fe3O4 NPs. The incorporation of higher loadings of A‐Fe3O4 NPs in the membrane matrix significantly improved the adsorptive ability and hydrophilicity of the adsorbent, leading to improved membrane water permeance, adsorption rate, and adsorption‐filtration properties. The water contact angle decreased from 70.7° to 63.2°, and the flux increased from 239.9 to 443.8 L/m2.h, while overall membrane porosity increased from 43.4% to 51.9%.

AbstractAn attractive candidate to reduce dependence on fossil fuels and replace them by renewable sources is represented by concentrated solar power (CSP) technology, whose wide deployment is still hindered by its high investment costs. In CSP linear collector plants, a key component with high technological content may be identified in receiver tubes, that are traversed by heat transfer fluid and located on focal line on which solar radiation is concentrated by mirrors. The proposed work aims at developing spectrally selective coatings for receiver tubes able to overcome state‐of‐the‐art technological limitation in terms of both vacuum encapsulation and maximum operative temperature, currently limited at 550°C for molten salts CSP plants. To this aim, a multilayer structure was designed and developed for coating a receiver tube to be employed in open‐air environment at temperature of 600°C. The multilayer coating is based on tungsten chromium titanium infrared reflector and includes a solar absorber layer developed with two alternative methods of reactive sputtering and thermal oxidation respectively, finally covered by antireflective and barrier bi‐layer of aluminum oxide and silica. Thermal stability was demonstrated of the new developed coatings, since only small variations were measured of the optical parameters after more than 2000 h of aging in open air conditions at temperature of 600°C (on average less than 5%), with final measured solar absorptance αs of 73% and 87% and thermal emissivity εth at 600°C of 18% and 27% for aged multilayer structures including the absorber layer obtained through thermal oxidation and sputtering process, respectively. These results pave the way for further improvement in terms of both optical performance and operative temperature increase, allowing to enhance efficiency and lower costs, thus contributing to ease to deployment of CSP technology.

Published: April 2023

AbstractDue to the dependence of consensus theory on multi‐agent systems (MAS) and the need to openly exchange status information with neighbors on each agent, private status and information are inevitably exposed to the public. In this paper, we present a consensus privacy protection algorithm to solve the consensus privacy problem of second‐order MAS. The proposed approach is based on the Paillier algorithm with semi‐homomorphic characteristics while combining a distributed control perspective to solve the privacy issues of sharing system status information. Under the conditions of our design, as long as there is at least one trustworthy neighbor node, the privacy of the topology nodes can be protected, and thus, the interconnected nodes are unable to detect the state information of systems from one another. We provide a new method for the privacy of the state information of the discrete‐time MAS and use restricted hardware devices to implement the consensus control. Finally, experiments verify the effectiveness of our method, while meeting the actual applicability
