Exciton-assisted electron tunnelling in van der Waals heterostructures.

The control of elastic and inelastic electron tunnelling relies on materials with well-defined interfaces. Two-dimensional van der Waals materials are an excellent platform for such studies. Signatures of acoustic phonons and defect states have been observed in current-to-voltage measurements. These features can be explained by direct electron-phonon or electron-defect interactions. Here we use a tunnelling process that involves excitons in transition metal dichalcogenides (TMDs). We study tunnel junctions consisting of graphene and gold electrodes separated by hexagonal boron nitride with an adjacent TMD monolayer and observe prominent resonant features in current-to-voltage measurements appearing at bias voltages that correspond to TMD exciton energies. By placing the TMD outside of the tunnelling pathway, we demonstrate that this tunnelling process does not require any charge injection into the TMD. The appearance of such optical modes in electrical transport introduces additional functionality towards van der Waals material-based optoelectronic devices.

Synergistic integration of copper-functionalization and smart release mechanisms for enhanced bacterial inactivation on polyethersulfone membranes

In this research, we describe the development of smart polyethersulfone (PES) membranes with superior antibacterial and antiadhesion properties. The strategy involved incorporating thermo-responsive polymers and copper oxide nanoparticles onto the membrane surface, which has not been previously reported. The study examined the surface and chemical characteristics of the membranes and discovered that the PNIPAm and P(NIPAm-co-AAm) brushes as well as copper oxide nanoparticles were successfully attached to the PES membrane surface. The antibacterial and release capabilities of the membranes were assessed against both gram-negative (E. coli) and positive (B. cereus) bacteria. The results indicate that while hydrophilicity and surface charge are relevant factors, they are not sufficient indicators for the antibacterial performance of a membrane. Instead, the biocidal properties of the surface materials were found to be critical in determining the antibacterial efficacy of the membrane. It has been observed that the method of killing bacteria that are attached to the membrane surface is more successful than the anti-adhesion approach, which aims to stop bacteria from attaching. The best biofouling reduction was observed in a dual-functionalized membrane with both effective antibacterial properties and additional anti-adhesion functionality. This work presents a promising solution to combat bacterial growth on surfaces and reduce feed pathogenicity during separation.

Synthesis and Characterization of Hydrophobic and Low Surface Tension Polyurethane

Polyurethane is a common polymeric coating, providing abrasion resistance, chemical durability, and flexibility to surfaces in the biomedical, marine, and food processing industries with great promise for future materials due to its tunable chemistry. There exists a large body of research focused on modifying polyurethane with additional functionalities, such as antimicrobial, non-fouling, anticorrosive action, or high heat resistance. However, there remains a need for the characterization and surface analysis of fluoro-modified polyurethanes synthesized with commercially available fluorinated polyol. In this work, we have synthesized traditional solvent-borne polyurethane, conventionally found in food processing facilities, boat hulls, and floor coatings, with polyurethane containing 1%, 2%, and 3% perfluoropolyether (PFPE). Polyurethane formation was confirmed by attenuated total reflectance Fourier-transform infrared (ATR-FTIR) spectroscopy, with the urethane band forming at 1730 cm−1 and the absence of free isocyanate stretching from 2275–2250 cm−1. X-ray photoelectron spectroscopy (XPS) was used to confirm perfluoropolyether polymerization with an increase in the atomic percentage of fluorine. Wettability and hydrophobicity were determined using a dynamic water contact angle with significant differences in advancing the water contact angle with the inclusion of perfluoropolyether blocks (PU–co–1PFPE 131.5° ± 8.0, PU–co–2PFPE 130.9° ± 5.8, and PU–co–3PFPE 128.8° ± 5.2) compared to the control polyurethane (93.6° ± 3.6). The surface orientation of fluorine supported the reduced critical surface tensions of polyurethane modified with PFPE (12.54 mN m−1 for PU–co–3PFPE compared to 17.19 mN m−1 for unmodified polyurethane). This work has demonstrated the tunable chemical qualities of polyurethane by presenting its ability to incorporate fluoropolymer surface characteristics, including low critical surface tension and high hydrophobicity.

Polyphenolic Gelatin-Based Bioadhesives

ConspectusBioadhesives are important for the future of medicine in their roles in wound closure and as measures to enhance wound healing. These adhesives are more effective and less invasive than conventional wound closure methods, such as surgical sutures or staples. Adhesive substances based on naturally occurring biological materials from living organisms harness phenolic compounds for their attachment to wet surfaces. For example, plants, such as Boston ivy, or animals, such as mussels, have evolved tissues that create optimal adhesion under a variety of challenging conditions, including in aqueous and saline environments. Current research aims at using biomimetic strategies to create a new generation of bioadhesives that will be better suited for medical use. Biomaterials design has evolved around integration of phenols with protein backbones among which gelatin has received particular attention due to its excellent bioactivity, biocompatibility, biodegradability, low cost, facile chemical tunability, and tissue-mimetic properties. Bioadhesion performance in these biomaterials is a strong function of polyphenolic functionality and the processing approach for their integration into hydrogel networks. A number of studies have used phenolic small molecules to modify biomacromolecules chemically for bioadhesion. One of the major hurdles in these studies is insufficient phenolic uptake due to low-yield modification chemistries and inherently limited functionalization capacity of proteins. Polyphenols are an attractive toolbox for bioadhesive design, as they not only enable stronger interactions with various substrates but also act as cross-linking points, strengthening polymer network cohesion. In addition, the cross-linking mechanism used for gelation of bioadhesives should be compatible with polyphenolic moieties, as, for instance, free-radical polymerization in the presence of phenolic compounds is compromised by their free-radical scavenging effects. Polyphenolic compounds derived synthetically from phenolic small molecules as well as those occurring naturally, such as tannins, have added a large library of additional functionality, such as antimicrobial and photothermal responsiveness, calling for further developments for applications in wound management.In this Account, we review several recent breakthroughs in polyphenol-integrated gelatin that have been analyzed in the context of their use as bioadhesives. Polyphenols play important roles in covalent and noncovalent interactions with functional groups in biological substrates, including keratins, connective tissue, or soft internal tissues. We consider different polyphenol-carrying compounds for modification including catecholamines, phenolic amino acids, tannins, and lignins. We then discuss how these polyphenolic materials can be fabricated to mimic naturally derived bioadhesives through infusion, physical mixing, and copolymerization. We discuss the implications of using these bioadhesives, questioning their viability and prospects. Finally, we highlight current challenges and future opportunities for taking polyphenolic bioadhesives closer to clinical translation.

Competent Energy Executing Structure in the Solar Sheet in the IoT Environment

A desirable array of electrical generating techniques reserves, utilizing renewable energy sources such as solar power, wind, and tidal energy. Many research companies have thought about primitive power generation technology, but electricity produced from these resources is not adequate and satisfactory and the power demands are that effective and intelligent systems are required to deliver the high energy level and the proper power delivery. A variety of other improved approaches can be used for successful manufacturing and delivery processes, although certain additional functionality would be needed to improve the operation. This article, thus, introduces an uncommon management framework and discusses efficiently the effects of the control of energy generation and delivery from renewable resources. Mainly for enriching the features Internet of Things (IoT) gets implemented for doubling the process output. IoT is a class of worldwide global neural networks in the cloud that acquaintances various things. The IoT is an elegantly connected device and framework which contain gleaming machine connecting and communicating with different machines, environments, and matter and will rise to meet a new challenge. Furthermore, this investigation here depends on the empowered solar panel monitoring and search for the proficient way to expand more power from solar radiation.

Thermoresponsive antifouling ultrafiltration membranes from mesophase templating

Nanostructured polymers synthesized by lyotropic liquid crystal (LLC) templates with normal hexagonal (H1) structure exhibit a 3D-continuous transport path, which makes them ideal for membrane separation application. Incorporating additional functionality, especially stimuli-responsiveness, in such an ordered structure provides even more application opportunities. In this work, we present the first successful synthesis of H1-structured thermoresponsive ultrafiltration (UF) membranes via LLC templating. The membrane contains thermoresponsive Pluronic P84 diacrylate (P84DA) which not only acts as the monomer and structure-directing amphiphile, but also enables the pore size change with temperature. Experimental studies reveal that the swelling capacity of H1-templated polymer as well as permeability and selectivity of the obtained membrane can be altered by changing the temperature. Increasing the temperature from 25 to 45 °C increases the normalized flux from 28 to 68 L m−2 h−1 μm and molecular weight cut-off (MWCO) from 2200 to 3900 Da. Furthermore, the membrane shows an outstanding fouling resistance against different solutes.

Dual receptor specific nanoparticles targeting EGFR and PD-L1 for enhanced delivery of docetaxel in cancer therapy

Dual-receptor targeted (DRT) nanoparticles which contain two distinct targeting agents may exhibit higher cell selectivity, cellular uptake, and cytotoxicity toward cancer cells than single-ligand targeted nanoparticle systems without additional functionality. The purpose of this study is to prepare DRT poly(lactic-co-glycolic acid) (PLGA) nanoparticles for targeting the delivery of docetaxel (DTX) to the EGFR and PD-L1 receptor positive cancer cells such as human glioblastoma multiform (U87-MG) and human non-small cell lung cancer (A549) cell lines. Anti-EGFR and anti-PD-L1 antibody were decorated on DTX loaded PLGA nanoparticles to prepare DRT-DTX-PLGA via. single emulsion solvent evaporation method. Physicochemical characterizations of DRT-DTX-PLGA, such as particle size, zeta-potential, morphology, and in vitro DTX release were also evaluated. The average particle size of DRT-DTX-PLGA was 124.2 ± 1.1 nm with spherical and smooth morphology. In the cellular uptake study, the DRT-DTX-PLGA endocytosed by the U87-MG and A549 cells was single ligand targeting nanoparticle. From the in vitro cell cytotoxicity, and apoptosis studies, we reported that DRT-DTX-PLGA exhibited high cytotoxicity and enhanced the apoptotic cell compared to the single ligand-targeted nanoparticle. The dual receptor mediated endocytosis of DRT-DTX-PLGA showed a high binding affinity effect that leads to high intracellular DTX concentration and exhibited high cytotoxic properties. Thus, DRT nanoparticles have the potential to improve cancer therapy by providing selectivity over single-ligand-targeted nanoparticles.

Room Temperature Bias-Selectable, Dual-Band Infrared Detectors Based on Lead Sulfide Colloidal Quantum Dots and Black Phosphorus

A single photodetector capable of switching its peak spectral photoresponse between two wavelength bands is highly useful, particularly for the infrared (IR) bands in applications such as remote sensing, object identification, and chemical sensing. Technologies exist for achieving dual-band IR detection with bulk III–V and II–VI materials, but the high cost and complexity as well as the necessity for active cooling associated with some of these technologies preclude their widespread adoption. In this study, we leverage the advantages of low-dimensional materials to demonstrate a bias-selectable dual-band IR detector that operates at room temperature by using lead sulfide colloidal quantum dots and black phosphorus nanosheets. By switching between zero and forward bias, these detectors switch peak photosensitive ranges between the mid- and short-wave IR bands with room temperature detectivities of 5 × 109 and 1.6 × 1011 cm Hz1/2 W–1, respectively. To the best of our knowledge, these are the highest reported room temperature values for low-dimensional material dual-band IR detectors to date. Unlike conventional bias-selectable detectors, which utilize a set of back-to-back photodiodes, we demonstrate that under zero/forward bias conditions the device’s operation mode instead changes between a photodiode and a phototransistor, allowing additional functionalities that the conventional structure cannot provide.

Co/Pd-based spin-valves with perpendicular magnetic anisotropy on flexible substrates. Direct deposition vs transfer-and-bonding approaches

Flexible spintronics is an emerging field of research that has received increasing attention due to the additional functionalities that are allowed (lightweight, flexibility, shape-ability, wearability) with respect to conventional rigid systems. In this work, different strategies for the fabrication of flexible spintronic devices with perpendicular magnetic anisotropy are compared, i.e., transfer-and-bonding approaches exploiting wet and dry lift-off methods, and direct deposition on flexible substrates. To evaluate the potential of the proposed strategies, Co/Pd-based giant magneto-resistive spin-valves including a synthetic antiferromagnet reference electrode were investigated. Such stacks represent a demanding model system, owing to the large number of interfaces whose quality strongly affects the overall magnetic and electric performances. The advantages and drawbacks of the different strategies are discussed to provide crucial indications for the development of flexible spintronic devices of any complexity. Based on the results, the most suitable option for achieving high-quality heterostructures on large area surfaces via direct deposition is using polyethylene naphthalate (Teonex®) tapes, provided that the processing and operating temperatures are relatively low (<525 K). On the other hand, if the process requires higher temperatures, the dry lift-off method exploiting the low adhesion between an Au underlayer and the SiOx/Si(100) substrate is the preferred alternative.

Catalytic hydrolysis of epoxyfatty esters with solid sulfonic acids

Four sulfonic resins are able to promote the hydrolysis of several epoxyfatty esters becoming a very interesting strategy to obtain polyols from epoxyfatty derivatives. The choice of the aqueous solvent and temperature is critical to improve the accessibility of reagents to the acidic catalytic sites. Tert-butanol/water mixture as solvent at 80 °C allows to obtain good results with all resins. The recovery of the heterogeneous catalyst during at least 11 reaction cycles avoids the drawbacks of the homogeneous ones including corrosion problems. In addition, this procedure can be applied to several epoxyfatty esters with different chain size, stereochemistry of the epoxide or with additional functionalities, obtaining good yields of structurally different polyols.

This Sample Seems to Be Good Enough! Assessing Coverage and Temporal Reliability of Twitter’s Academic API

Because of its willingness to share data with academia and industry, Twitter has been the primary social media platform for scientific research as well as for consulting businesses and governments in the last decade. In recent years, a series of publications have studied and criticized Twitter's APIs and Twitter has partially adapted its existing data streams. The newest Twitter API for Academic Research allows to "access Twitter's real-time and historical public data with additional features and functionality that support collecting more precise, complete, and unbiased datasets. The main new feature of this API is the possibility of accessing the full archive of all historic Tweets. In this article, we will take a closer look at the Academic API and will try to answer two questions. First, are the datasets collected with the Academic API complete? Secondly, since Twitter's Academic API delivers historic Tweets as represented on Twitter at the time of data collection, we need to understand how much data is lost over time due to Tweet and account removal from the platform. Our work shows evidence that Twitter's Academic API can indeed create (almost) complete samples of Twitter data based on a wide variety of search terms. We also provide evidence that Twitter's data endpoint v2 delivers better samples than the previously used endpoint v1.1. Furthermore, collecting Tweets with the Academic API at the time of studying a phenomenon rather than creating local archives of stored Tweets, allows for a straightforward way of following Twitter's developer agreement. Finally, we will also discuss technical artifacts and implications of the Academic API. We hope that our work can add another layer of understanding of Twitter data collections leading to more reliable studies of human behavior via social media data.

Cartographic Design and Processing of Originally Printed Historical Maps for Their Presentation on the Web

On the example of our project on the creation of the historical web atlas on Czech history, we introduce the process of adapting originally printed historical maps for their presentation in the web environment, which overcomes the shortcomings of standard approaches in similar projects based on printed predecessors published only as zoomable scanned analogues or default GIS maps. To simplify the originally complex map and to increase the information potential of the maps, we propose seven different types of additional map functionality according to the specific characteristics of the original map content. In addition, we present a set of rules, principles, recommendations, and methods for the cartographic design and processing of originally printed historical maps that should be considered when they are prepared for presentation on the web, including the description of the specific visualisation processes for the proposed types of map functionality. The proposed complex methodology can be applied to similar projects focused on the conversion of originally printed maps to the web and may contribute to improving the quality of the visualisation and presentation of historical maps on the web in general.

Incorporation of Tb and Gd improves the diagnostic functionality of magnetotactic bacteria.

Magnetotactic bacteria are envisaged as potential theranostic agents. Their internal magnetic compass, chemical environment specificity and natural motility enable these microorganisms to behave as nanorobots, as they can be tracked and guided towards specific regions in the body and activated to generate a therapeutic response. Here we provide additional diagnostic functionalities to magnetotactic bacteria Magnetospirillum gryphiswaldense MSR-1 while retaining their intrinsic capabilities. These additional functionalities are achieved by incorporating Tb or Gd in the bacteria by culturing them in Tb/Gd supplemented media. The incorporation of Tb provides luminescence properties, enabling potential applications of bacteria as biomarkers. The incorporation of Gd turns bacteria into dual contrast agents for magnetic resonance imaging, since Gd adds T1 contrast to the existing T2 contrast of unmodified bacteria. Given their potential clinical applications, the diagnostic ability of the modified MSR-1 has been successfully tested in vitro in two cell models, confirming their suitability as fluorescent markers (Tb-MSR-1) and dual contrast agents for MRI (Gd-MSR-1).

Design of multifunctional polymeric binders in silicon anodes for lithium‐ion batteries

AbstractSilicon (Si) is a promising anode material for lithium‐ion batteries (LIBs) owing to its tremendously high theoretical storage capacity (4200 mAh g−1), which has the potential to elevate the energy of LIBs. However, Si anodes exhibit severe volume change during lithiation/delithiation processes, resulting in anode pulverization and delamination with detrimental growth of solid electrolyte interface layers. As a result, the cycling stability of Si anodes is insufficient for commercialization in LIBs. Polymeric binders can play critical roles in Si anodes by affecting their cycling stability, although they occupy a small portion of the electrodes. This review introduces crucial factors influencing polymeric binders' properties and the electrochemical performance of Si anodes. In particular, we emphasize the structure–property relationships of binders in the context of molecular design strategy, functional groups, types of interactions, and functionalities of binders. Furthermore, binders with additional functionalities, such as electrical conductivity and self‐healability, are extensively discussed, with an emphasis on the binder design principle.

0884 User Needs and Preferences for a Smartphone App to Treat Insomnia in Cancer Survivors

Abstract Introduction Cancer patients with insomnia have unique needs and require tailored healthcare interventions. iCANSleep is a mobile health intervention aimed at providing evidence-based insomnia treatment via a smartphone app. As part of a user-centered development process, virtual needs assessment interviews were conducted with cancer survivors who report insomnia to determine the needs and preferences of this patient group for insomnia treatment. Methods 22 cancer survivors from 5 Canadian provinces completed an online survey and participated in a needs assessment interview. Surveys were analyzed using descriptive statistics, while interviews were transcribed and analyzed using thematic analysis. Results 81.8% (18/22) of cancer survivors report that their insomnia started or was exacerbated during the time of their cancer diagnosis and treatment. Of the participants who discussed insomnia with a medical provider, hypnotic medications were prescribed in 64.3% (9/14) of cases. With some exceptions, participants reported strong familiarity with smartphone technology, had experience using apps for health management, and found an insomnia treatment app highly acceptable. Participant-identified facilitators of app use included ease of access, lack of cost, anonymity, empirical basis, and recommendation by local care teams. Smartphone ownership, cumbersome user interface, and limited access to internet were raised as potential challenges of implementation. Additional functionality identified by participants included options to link consumer wearable devices, additional modules to address comorbid conditions such as pain and anxiety, and an anonymous peer support forum. Conclusion Mobile apps hold promise as an avenue for the effective delivery of insomnia treatment; however, treatments must be evidence-based, and apps must be designed for maximum ease of use. Findings provide novel insight into how to best promote uptake and sustained use of mobile health interventions in cancer survivors and will be used to develop functional guidelines.

The non-innocent role of cobalt in manipulating the magnetic and electric properties of mesoporous silica thin films

SiO2 does not have magnetic elements; therefore, it behaves as a diamagnetic material with a possible paramagnetism due to oxygen vacancy defects. Incorporation of magnetic elements and pores into SiO2 films can add an additional functionality to its dielectric and insulating properties. Herein we report the incorporation of Co element into the mesoporous framework of SiO2 (Co–SiO2) thin films through chemical sol-gel based-spin coating processes. The thus obtained Co–SiO2 thin film exhibits transition in the magnetic properties, increase in the specific surface area and a decrease in the leakage current while maintaining better electric conductivity. For comparison, the bare mesoporous SiO2 (m-SiO2) films were prepared at identical conditions. Interestingly, a S-type shape on the isothermal magnetization measurements versus magnetic field (M vs. H) curves appeared at 5 K in case of the Co–SiO2 films, and a paramagnetic behavior was observed at 50 K and above. The temperature-dependent magnetization (M vs. T) measurements of the Co–SiO2 films also showed an increase of magnetization below 50 K. It is anticipated that Co substitutes Si although presence of the CoO and/or Co3O4 phases cannot be completely ruled out. These results support the idea that a ferromagnetic-like transition takes place in the Co-doped SiO2 films below 50 K due to Co doping. At the same time, a reduction in the leakage current density was determined in Co–SiO2, while maintaining better charge transfer in 1.0 M KOH for ion conducting devices.

Azido‐Functionalized Fullerenes, Perylenediimide, Perylene, and Tetraphenylethylene as Crosslinkers for Applications in Materials Science

AbstractThis study presents the synthesis and characterization of novel azido molecules with demonstrated crosslinking ability when used as additives in polymer/fullerene organic solar cells. These compounds derived from fullerenes C60 and C70, or dyes from perylenediimide, perylene and tetraphenylethylene frameworks, bearing a different number of azido groups, are of particular interest to stabilize and increase the thermal stability of the device morphology. In particular, the electro and photoactive dye derivatives allow the introduction of additional functionality with the possibility of extending the absorption domain of the photoactive layer. In addition, and more broadly, such azido crosslinkers could find applications in the field of optoelectronic devices as a simple and cheap strategy to improve the performance and long‐term stability of organic solar cells, perovskites solar cells, or organic light‐emitting diodes.

Digital Standardization of Lean Manufacturing Tools According to Industry 4.0 Concept

Standardization is a key element in the effective use of lean manufacturing methodologies and tools for achieving process sustainability. Their combination is conducive to eliminating waste and improving the efficiency of production processes and guarantees the company that employees use the most efficient tools and do not waste time on unnecessary activities. These activities can be further improved by using digital solutions, in accordance with the concept of Industry 4.0. Therefore, the authors have developed the e-Lean system, whose task is to digitize selected lean manufacturing tools. The subject of this work is analysis of the functionality and effectiveness of the essential part of the e-Lean system in the form of specialized TPM (Total Productive Maintenance) software as an application. During implementation in a construction production company, the TPM application was tested by lean manufacturing and maintenance specialists. The research consisted of assessing the functionality and efficiency of processes in relation to conventional TPM solutions. Additional functionalities of the e-Lean system have been confirmed, such as systemic approval of machinery inspection, which requires passing all necessary steps at individual inspection points, direct access for supervisors to the results of inspection activities and their status, direct and easy access to photographic documentation of machines added during inspection both in optimization of working time and its course (e.g., the optimal number of steps taken by the employee during the inspection), as well as an efficient system of motivating employees (collecting points). The improvement in the effectiveness of processes was determined by measuring the control times for three control points (polymerization furnace, packing area, and defibering machines). The average control time was reduced from 16,200 to 13,923 s. Thus, thanks to the use of the application, it was found that the efficiency of using the TPM tool was increased by approx. 15% compared to previously used non-digital solutions.

Four-Dimensional Printing of a Fiber-Tip Multimaterial Microcantilever as a Magnetic Field Sensor

“Lab on Fiber” technology integrates different micro- and nanoscale structures or materials onto optical fibers to create additional functionality. With the advanced femtosecond (Fs) laser-induced two-photon polymerization (TPP) technology, polymer microstructures printed on a fiber tip have great potential as micro-optical sensors. However, additional functionalization is usually required, which is costly and complex. Based on the advanced four-dimensional (4D) printing theory, for the first time, a successive multimaterial on-fiber TPP strategy is proposed here, and a fiber-tip polymer microcantilever-based magnetic sensor is prepared in one step. First, the cantilever and the supporting base on the fiber tip are printed by TPP, and then the magnetically responsive cube on the cantilever tip is printed with a self-made magnetic fluid photoresist. The whole process is completed in one step without additional treatment. The prepared sensor shows a minuscule size and a high magnetic sensitivity of 119 pm mT–1 in the range of 0–90 mT, suitable for weak or microspace magnetic field measurement at high spatial resolution. Especially, the proposed 4D successive on-fiber TPP strategy can be extended to other stimulus-responsive materials, providing new guidance for manufacturing various stimulus-responsive microsensors and microactuators on the fiber tip.
