Multiple Narrowband Bidirectional Self‐Powered Organic Photodetector with Fast Response
Authors: Xia Yuxin , Georgiadou Dimitra G. 
Published: August 2024

AbstractBenefiting from the discovery of novel organic semiconductor materials bearing tunable absorption characteristics, narrowband organic photodetectors (OPDs) with improved performance are reported. Alongside new photoactive materials synthesis, several device engineering strategies are introduced to achieve narrowband OPDs, allowing less dependence of the device performance on the synthetic variation control, such as batch‐to‐batch differences in molecular weight. However, fabrication of multiband OPDs remains a challenge. Current solutions are usually based on vertical multi‐stacking of photosensitive layers with different absorption spectra and voltage‐modulated charge collection/injection, which renders the device fabrication too complex, while their response speed and band selectivity is limited. In this work, the concept of optical cavity is adopted to demonstrate self‐powered and fast response speed single‐junction bidirectional organic photodetectors with dual narrowband detection in the ultraviolet (UV) and visible part of the spectrum. Application of these devices in encrypted UV communication is successfully demonstrated. A third band in the near infrared (NIR) is possible to be isolated, rendering these high‐performing and simple to manufacture multiband OPD devices attractive for high‐resolution imaging and optical wireless communication.

AbstractBiomaterials are widely employed across diverse biomedical applications and represent an attractive strategy to explore how extracellular matrix components influence cellular response. In this study, the previously developed streptavidin platforms is aimed to use to investigate the role of glycosaminoglycans (GAGs) in bone morphogenetic protein 2 (BMP2) signaling. However, it is observed that the interpretation of findings is skewed due to the GAG‐unrelated, non‐specific binding of BMP2 on components of biomaterials. Non‐specific adsorption of proteins is a recurrent and challenging issue for biomaterial studies. Despite the initial incorporation of anti‐fouling polyethylene glycol (PEG) chains within biomaterials, the residual non‐specific BMP2 adsorption still triggered BMP2 signaling within the same range as conditions of interest. The various options are explored to prevent BMP2 non‐specific adsorption and a successful blocking condition involving a combination of bovine serum albumin and trehalose are identified. Furthermore, the effect of this blocking step improved when using gold platforms instead of glass, particularly with Chinese hamster ovary (CHO) cells. With this specific example, it is suggested that non‐specific adsorption of BMPs on biomaterials may be a general concern – often undetected by classical surface‐sensitive techniques – that needs to be addressed to better interpret cellular responses.

AbstractBackgroundThe Levodopa Equivalent Daily Dosage (LEDD) calculation algorithms help in capturing and harmonization of Parkinson's Disease (PD) therapies. Analyzing these updates is essential for validating their effectiveness.ObjectiveTo assess updated LEDD conversion factors in capturing the newer therapies in PD and therapy modules in different geographical cohorts.MethodsData were sourced from 10 Centers from 6 countries representing 2 different continents. The study compared the LEDD conversion factors proposed by Tomlinson et al and Jost et al, alongside investigating demographic disparities.ResultsThe analysis involved 2943 subjects; 87% (n = 2577) met the UK Brain Bank criteria for PD. The LEDD differed significantly across methodologies (Tomlinson vs. Jost, 598 mg vs 610 mg, P < 0.0001). Geographical disparities highlighted variations in PD onset age (P < 0.0001). Jost and Tomlinson's calculations demonstrated consistency within but significant differences across countries (P < 0.0001).Age at onset revealed statistically significant differences in LEDD requirements (P < 0.0001), which were particularly higher in 21–50 years (718 mg vs 566 mg). This subgroup also demonstrated increased usage of non‐Levodopa therapies (P < 0.0001). Men exhibited higher total LEDD (P = 0.001). 34% reported dyskinesia, associated with higher LEDD (756 mg, P < 0.0001). Surgically treated patients also had higher LEDD (P < 0.0001) and a significant difference between Jost and Tomlinson dosages (761 mg vs716mg) reflecting the incorporation of newer therapeutic molecules.ConclusionThis analysis delineates the importance of updated LEDD algorithms and intricacies in the landscape of PD treatment, underscored by geographical, age‐related, and gender‐specific variations, in real‐life management scenarios.

AbstractThis research paper delves into the enhancement of wastewater treatment through the design and synthesis of advanced photocatalytic materials, focusing on the effects of sodium (Na) substitution in Ca1‐xNaxTa0.5Ti0.5O3 perovskites. By employing various analytical techniques such as X‐ray diffraction, Field Emission Scanning Electron Microscopy, Transmission Electron Microscopy and UV‐vis spectroscopy, the study examines the transition of these perovskites from tetragonal to orthorhombic structures and observes a reduction in Ca content with Na substitution, which also favors the cubic phase formation and inhibits secondary phases. Significantly, magnetic property analysis uncovers an unexpected ferromagnetic ordering in these perovskites, including compositions traditionally viewed as non‐magnetic. The photocatalytic tests reveal a significant improvement in degrading Rhodamine B dye under visible light, particularly in samples with higher Na levels, attributed to enhanced light absorption and efficient electron processes. The study highlights the optimal Na substitution level for peak photocatalytic performance, offering valuable insights into the complex interplay between structural, magnetic, and photocatalytic properties of these perovskites, and their potential in various applications, thereby contributing to the advancement of wastewater treatment technologies.

Published: August 2024

AbstractTo improve the subpar lubricating performance of epoxy resin, this paper presents the preparation of a novel bimetallic phyllosilicate featuring a distinctive rice‐granular morphology, which incorporates nickel and iron metal cations through a facile hydrothermal process. These phyllosilicates were then integrated into the epoxy matrix to form composites. A comprehensive analysis of the target product validates the rationality of the synthesis strategy for the as‐prepared rice‐granular bimetallic nickel/iron phyllosilicate, demonstrating a homogeneous hierarchical structure with numerous tiny nanosheets of nickel/iron phyllosilicate grown in situ on the flat surfaces of the rice‐granular metal–organic frameworks. An adequate addition of nickel/iron phyllosilicates allows for excellent dispersion within the matrix and establishes strongly bonded interfaces, steadily increasing the elastic modulus and hardness. Notably, the average friction coefficients decrease from 0.515 for the pure resin to 0.450 for the composites when the filler content reaches 7%, indicating a significant solid lubrication effect. In contrast, adding just 1% nickel/iron phyllosilicate moderately improves wear resistance, elongation at break, and tensile strength. Furthermore, it was found that as the filler content increased, the weight loss rate was reduced by approximately 43.8%, while the residual char increased by 74.2%, significantly enhancing the thermal stability of epoxy composites at high temperatures. This study offers a promising approach to preparing self‐lubricated epoxy composites with favorable mechanical and thermal properties.Highlights
NiFePS was successfully synthesized via a facile two‐step self‐polymerization.
Excellent mechanical properties of composites could be achieved with low content of NiFePS.
The friction coefficient and wear rate were lowered remarkably.
The friction mechanism was solid lubrication.

AbstractThe quest for mechanoluminescence (ML) in zinc sulfide (ZnS) spans more than a century, initially sparked by observations of natural minerals. There has been a resurgence in research into ML materials in recent decades, driven by advances in optoelectronic technologies and a deeper understanding of their luminescent properties under mechanical stress. ZnS, in particular, has garnered attention owing to its remarkable ability to sustain luminescence after more than 100,000 mechanical stimulations, positioning it as a standout candidate for optoelectronic applications. In contrast to conventional photoluminescent and electroluminescent light sources, ZnS composite elastomers have emerged as flexible, stretchable self‐powered light sources with considerable practical implications. This review introduces the development history, ML mechanisms, prototype ML devices, ZnS‐based ML material preparation methods, and their diverse applications spanning environmental mechanical‐to‐optical energy conversion, E‐signatures, anti‐counterfeiting, wearable information sensing devices, advanced battery‐free displays, biomedical imaging, and optical fiber sensors for human–computer interactions, among others. By integrating insights from ML‐optics, mechanics, and flexible optoelectronics, and by summarizing pertinent perspectives on current scientific challenges, application technology hurdles, and potential solutions for emerging scientific frontiers, this review aims to furnish fundamental guidance and conceptual frameworks for the design, advancement, and cutting‐edge application of novel mechanoluminescent materials.
Integrating UAV‐Based Topographic and Geomorphic Analysis for the Development of River Rehabilitation Plans in Semi‐Urban Settings
Authors: Sarkar Dipro , Sinha Rajiv 
Published: August 2024

ABSTRACTSeveral rivers across the world face multiple threats from natural as well as human‐induced alterations in hydrology and morphology over time. Researchers have proposed several measures to instigate a healthier response by river rehabilitation or rejuvenation (depending on the condition of the river) to mitigate the impacts of causal factors. Investigating the causal factors of degradation is highly dependent on historical data, the availability of which depends on multiple considerations and is sometimes difficult to obtain, especially for a small river. A range of rehabilitation options have been explored by researchers among which geomorphology‐based approaches have gained importance as they are based on process‐based understanding and aim to reconstruct the river form for improving the river status. This paper introduces a novel method that uses very high‐resolution UAV data to analyze the topography and geomorphology of a small monsoon‐fed Sakri River in Central India. We aim to understand the anthropogenic factors responsible for its degradation with a particular focus on siltation and propose a river rejuvenation plan by creating the baseline data. The Sakri River supports 23 villages and a small town called Kawardha. The river presently has scanty surface flow and is unable to sustain the community. We mapped the entire river course using a UAV and identified 118 problematic sites, including 68 interventions along the 50 km stretch of the river. We have identified siltation as the primary problem at most sites caused by poorly designed interventions and a reduction in flow. We divided the river into 17 reaches and classified them into different states of criticality based on the identified problems and accumulated sediment volume behind the interventions. We have estimated a sizable volume of siltation within the 17 reaches as 0.5 million m3. Our analysis led to the development of a process response system that describes the various factors responsible for the degradation of the Sakri River and has important implications for designing mitigation strategies. Our recommendations for remedial measures are based on careful evaluation of the efficacy of each intervention and we have suggested their renovation or removal. We have also suggested reach‐specific solutions such as canal lining, river training, channel alignment, and river bank protection to be implemented.

AbstractIntroductionEffective communication among agricultural stakeholders is the part and parcel of sustainable agricultural development. The study investigated farmers' exposure to communication media in receiving agriculture extension and rural advisory services (AERAS) for strengthening sustainable agricultural development.Materials and MethodsThe blended method research was conducted in Bangladesh employing both qualitative and quantitative approaches with 390 selected respondents utilizing structured questionnaire during 2022–2023. Statistical package for social science (SPSS) version 29, along with appropriate scales and scoring techniques were utilized to analyse the data.ResultsFindings indicated that most (94.6%) of the respondents get low to medium exposure to communication media, but majority (75.4%) of them were interested in contacting extension and advisory services without payment (73.6%). A significant portion (70.3%) of the participants perceived that, services delivered by extension officers facilitate farm sustainability. It was also found that respondents were mostly exposed to personal media ( = 377.4) whereas less exposed to mass media ( = 177.8) for desired services. Moreover, knowledge, proximity to office, access to extension services, organizational participation, innovativeness, training exposure were identified as influential factors increasing the extent of communication exposure.ConclusionThe results can assist concern departments as well as policymakers to update the curriculum, principles, or module for incorporating effective communication at farm level and modifying the diffusion of innovation systems for farm sustainability.
Significant Enhanced Electrochemiluminescence Performance of 6‐Methoxychromone/S2O82− System By 2‐Naphthalene Sulfonic Acid as Co‐reaction Accelerator and its Application

Published: August 2024

AbstractIn this paper, the novel ECL sensor of the 6‐methoxychromone (6‐MC)/S2O82− system was designed by using 2‐naphthalene sulfonic acid (2‐NSA) as a co‐reaction accelerator. Fluorescence, ECL spectrum, and cyclic voltammetry (CV) were used to explore extensively the ECL mechanism of the system. It is worth pointing out that 2‐naphthalene sulfonic acid (2‐NSA) was first proposed as a co‐reaction accelerator, reacting with the coreactant K2S2O8 rather than the luminophore, promoting the generation of additional oxidant SO4− from S2O82−, thus amplifying the ECL signal. Furthermore, under the optimal experimental conditions, the high sensitivity of the 2‐naphthalene sulfonic acid (2‐NSA)+6‐methoxychromone (6‐MC)/S2O82− system was realized for the detection of methyl violet (MV) in the linear range of 10−8~10−2 M, with a detection limit of 5.14×10−10 M. In addition, this find offers some guidance for further developing co‐reaction accelerators with excellent performance in the future.

AbstractThe growing field of nanotechnology presents opportunity for applications across many sectors. Nanostructures, such as nanoparticles, hold distinct properties based on their size, shape, and chemical modifications that allow them to be utilized in both highly specific as well as broad capacities. As the classification of nanoparticles becomes more well‐defined and the list of applications grows, it is imperative that their toxicity be investigated. One such cellular system that is of importance are cellular membranes (biomembranes). Membranes present one of the first points of contact for nanoparticles at the cellular level. This review will address current studies aimed at defining the biomolecular interactions of nanoparticles at the level of the cell membrane, with a specific focus of the interactions of nanoparticles with prominent lipid systems.

AbstractA novel approach for investigating the formation of solid electrolyte interphase (SEI) in Na‐ion batteries (NIB) through the coupling of in situ liquid electrochemical transmission electron microscopy (ec‐TEM) and gas‐chromatography mass‐spectrometry (GC/MS) is proposed. To optimize this coupling, experiments are conducted on the sodiation of hard carbon materials (HC) using two setups: in situ ec‐TEM holder and ex situ setup. Electrolyte (NP30) is intentionally degraded using cyclic voltammetry (CV), and the recovered liquid product is analyzed using GC/MS. Solid product (µ‐chip) is analyzed using TEM techniques in a post‐mortem analysis. The ex situ experiments served as a reference to for insertion of Na+ ions in the HC, SEI size (389 nm), SEI composition (P, Na, F, and O), and Na plating. The in situ TEM analysis reveals a cyclability limitation, this issue appears to be caused by the plating of Na in the form of a “foam” structure, resulting from the gas release during the reaction of Na with DMC/EC electrolyte. The foam structure, subsequently transformes into a second SEI, is electrochemically inactive and reduces the cyclability of the battery. Overall, the results demonstrate the powerful synergy achieved by coupling in situ ec‐TEM and GC/MS techniques.

AbstractThe controlled regulation of A‐site in rare earth manganate perovskites can orderly arrange the electronic states, leading to the emergence of unique transport properties. However, it is challenging to balance crystal structure stability and property variations during the multi‐ion doping. In this study, a series of multivalent manganate perovskites are synthesized by hydrothermal method through the A‐site multielement doping, which enables the manganese atoms with varying valence states to orderly arrange at the B site. Powder X‐ray diffraction (PXRD) and X‐ray absorption spectra (XAS) confirm that the splitting of the K─O hybrid orbitals in the crystal effectively prevents any distortion of the MnO6 octahedron, thereby facilitating the ordered arrangement of Mn (III) ‐Mn (IV) ‐Mn (V) at the B‐site and promoting superstructure formation. The transient absorption spectra (TAS) reveals that the sequential arrangement of Mn (III) – Mn (IV) – Mn(V) better forms the charge transfer channels, and thereby makes the photodynamic properties of the sample composition‐dependent. These photodynamic properties will facilitate the study of exciton‐electron coupling behavior in LCKMO crystals during electrical transport.

AbstractIn this paper, a planar of small size Tapered slot Vivaldi antenna for mm‐Wave 5G application is proposed. The main goal can be presented by designing of a small size antenna with good performance antenna for mmWave and massive MIMO applications. The suggested antenna structure is portrayed by a size of 6.4 × 6 × 0.254 mm3 printed on a dielectric substrate (Roger/RT Duroid −5880) with εr = 2.2, and tanδ = 0.0009. The antenna displayed a small size and good performance with an impedance bandwidth equals 17.9 GHz ranging from 22.1 GHz to 40 GHz with the value of S11<−10 dB, which covers all mm‐Wave frequency bands. The antenna gain is found fluctuating from 6.2 dB up to 7.1 dB in the whole band, which the maximum gain value is found at 22.1 GHz. The radiation of the antenna is found the end‐fire type. The HFSS software package was used to design and simulate the proposed antenna structure. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
