Published: September 2023

Aims: The net return of pigeonpea cultivated is lower due to failure to implement recommended intercropping and modern technology in the farming community in eastern Uttar Pradesh. To compensate for this anomaly, ICAR-IIVR-KVK, Deoria performed On-Farm-Trials (OFTs) for the evaluation of pigeonpea + maize intercropping in farmers' fields in various adopted villages in the Deoria District of Eastern Uttar Pradesh.
Place and Duration of Study: The two year assessment and refinement study was carried out by the Krishi Vigyan Kendra, Malhana, Deoria, working under the ICAR-Indian Institute of Vegetable Research, Varanasi, UP, during 2015–16 to 2016-17.
Methodology: In the present study of sole pigeonpea crop and intercropping of pigeonpea + maize was evaluated through on-farm trials (OFTs) among selected farmers’ field during Kharif season 2015-16 to 2016-17 in the eastern region of Uttar Pradesh, India,. Technology options for assessment of sole pigeonpea crop (T1) and pigeonpea + maize (T2) with improved packages and practices developed by IIPR, Kanpur, Uttar Pradesh, were tested at five selected farmer’s field.
Results: Maximum average gross return (Rs 103460 ha-1), net return (Rs 71730 ha-1) and benefit cost ratio (3.2:1) were recorded under intercropping of pigeonpea + maize, which was 41.50 percent, 43.40 and 5.96 percent more than the sown of sole crop of pigeonpea (T1) for gross return, net return and benefit cost ratio respectively, during the period of the on-farm trial.
Conclusion: The higher value of the equivalent yield, the more feasible technology for the farming community of Eastern Uttar Pradesh, India.

Published: September 2023

Aims: To provide a systematic review on the occurrence of valproic acid syndrome, to, among others, elucidate the characteristics of this syndrome.
Study Design: A systematic review was performed.
Place and Duration of Study: Laboratory of Biomathematics of the Federal UINiversity of Alfenas, Minas Gerais State, Brazil, between June 2022 and July 2023.
Methodology: A systematic search of articles was performed using the CAPES Periodic plataform a searcher from the Education Ministry of Brazil that contains Web of Science, Scopus, MedLine and other bases, from 1984 to 2023. For this review, the subject’s “syndrome of valproic acid”, “valproic acid syndrome and toxicity”, “valproic acid syndrome and malformations” were searched together using the type of material “articles” in English language. Some articles about “pregnancy’s cares” were used for epistemological composition of this work content subjects as, for instance, “general toxicity” and “others (development; health care; …)”.
Results: From the 1061 articles after the exclusion and the inclusion criteria made with the subjects most pertinent to the objectives of this work, added with the subjects “pregnancy cares” and “others”; 1005 articles were excluded, remaining 56 ones. Four of total from 56 texts were 4 about “general toxicity”; 19 about “others”; 4 about “Pregnancy cares” and 29 about “valproic acid”.
Conclusion: The analysis of the articles studied in this work indicates that valproic acid is a teratogen that leads to a syndrome that receives its name in fetuses whose mothers use it as an anticonvulsant and mood stabilizer primarily used for treating conditions like epilepsy and bipolar disorder, causing several physical defects in general and behavioral defects due to the impairment of the neural system. In this sense, it is essential that the team caring for pregnant women know the history of the pregnant woman and check all the medications she is using and replace those with a teratogenic potential, especially if the patient has a diagnosis of mental illness such as depression.

Aims: The objective of this research work is to design and develop an IoT-based automated solar panel cleaning and real-time monitoring system using a microcontroller to improve the output and efficiency of a solar module at a low cost.
Study Design: Most of the time, dust over solar panels creates a barrier that obstructs the sun’s radiation and reduces their performance. As such, it is necessary to keep the solar panel clean to improve output power levels. We integrated the IoT technology along with a range of components, including a microcontroller, a NodeMCU, a servo motor, a DC motor-driven submersible pump, a Light Dependent Resistor (LDR), an LCD with driver IC, etc. to design the system. We developed the assembly language program for the microcontroller.
Place and Duration of Study: The work was conducted individually under the supervisor of a faculty member as a part of the final project work of the Master of Engineering degree in Electrical and Electronic Engineering at American International University Bangladesh (AIUB), Dhaka, Bangladesh. The student conducted his research work at AIUB for two consecutive semesters from September 2022 to May 2023.
Methodology: An LDR sensor detects the solar panel’s dirtiness and triggers the cleaning process through the microcontroller. The system monitors this continuously and real-time vital data is accessible to have some performance metrics, empowering timely maintenance actions to be triggered by the system and hence ensuring the maximum power output. The automated cleaning mechanism, driven by servo motors and mini submersible DC motor pumps, effectively removes dust and dirt from solar panels. An application was used to get real-time data through the internet to the user’s smartphone.
Results: The server data is accessed to observe the system performance. The cost analysis shows that this system offers a cost-effective and sustainable solution for maintaining clean solar panels and optimizing power output.
Conclusion: Such an automation system can contribute meaningfully to the progression of renewable power generation by significantly improving the efficiency and longevity of solar panels. Thus, we can have sustainable and efficient energy systems in the country by integrating IoT-based automation systems.

AbstractSinglet fission, a process by which one singlet exciton is converted into two lower energy triplet excitons, is sensitive to the degree of electronic coupling within a molecular packing structure. Variations in molecular packing can be detrimental to triplet formation and triplet–triplet separation, ultimately affecting the harvesting of triplets for electricity in organic photovoltaic devices. Here, six phase‐pure molecular packing structures of 6,13‐bis(triisopropylsilylethynyl)pentacene (TIPS‐pentacene) with varying optoelectronic properties are isolated using 2D lead halide perovskites as tunable, crystalline surfaces for crystallization. Transient absorption spectroscopy reveals that while triplet formation is fast (<100 fs) regardless of template structure, the increased ordering in perovskite‐templated samples speeds up triplet–triplet separation and recombination, providing evidence that the benefits of phase‐purity offset minor variations in molecular packing. Molecular dynamics modeling of the interface reveals that perovskite‐templating allows for closer packing of TIPS‐pentacene molecules for all perovskite templates. With an extensive number of organic molecule‐perovskite pairings, this work provides a methodology to use ordered, periodic surfaces to elucidate structure–property relationships of small organic molecules in order to adjust structural or optoelectronic responses, such as molecular packing and singlet fission.

AbstractHydrogels have emerged as prototypical stimuli‐responsive materials with potential applications in soft robotics, microfluidics, tissue engineering, and adaptive optics. To leverage the full potential of these materials, fabrication techniques capable of simultaneous control of microstructure, device architecture, and interfacial stability, that is, adhesion of hydrogel components to support substrates, are needed. A universal strategy for the microfabrication of hydrogel‐based devices with robust substrate adhesion amenable to use in liquid environments would enable numerous applications. This manuscript reports a general approach for the facile production of covalently attached, ordered arrays of microscale hydrogels (microgels) on silicone supports. Specifically, silicone‐based templates are used to: i) drive mechanical assembly of prepolymer droplets into well‐defined geometries and morphologies, and ii) present appropriate conjugation moieties to fix gels in place during photoinitiated crosslinking via a “graft from” polymerization scheme. Automated processing enabled rapid microgel array production for characterization, testing, and application. Furthermore, the stimuli‐responsive microlensing properties of these arrays, via contractile modulated refractive index, are demonstrated. This process is directly applicable to the fabrication of adaptive optofluidic systems and can be further applied to advanced functional systems such as soft actuators and robotics, and 3D cell culture technologies.

Published: September 2023

The nondiffusive directional transport of micro‐cargos, such as colloids, cells, or liposomes, is vital for living organisms, for example in the intracellular transport of cytoplasmic organelles along actin filaments or microtubules, and also in numerous applications in biomedicine and nanotechnology. Mimicking natural designs, the self‐assembly capacity of magnetic colloids is studied and exploited to construct different paths along which swarms of magnetic micro/nanoparticles can be guided. Driven transport is possible thanks to the combined effect of the magnetic microstructure of the self‐assembled tracks, adsorbed on a solid interface, and the application of a time‐dependent magnetic field. Nonadsorbed magnetic particles propel along the pre‐formed structures under the action of an externally controllable traveling potential ratchet, like molecular walkers. The transport mechanisms are determined by both the properties of the particles and the configuration of the applied field. Finally, it is shown how the proposed combination of self‐assembly and guided transport paves the way to the development of a new class of techniques, able to adapt ad hoc to the environment, and transport of microparticles along irregular profiles and/or crowded conditions. The technological interest is immediate, including drug delivery and controlled guidance of microcargos, in biological environments and microfluidic platforms.

Published: September 2023

AbstractMechanoluminescence (ML) materials are capable of converting applied stress into luminescent signals, and offer fascinating potential applications in biomedicine, safety testing, structural diagnosis, and mechanical sensing. Color‐responsive ML sensing, combined with quantitative evaluation of loaded stress, is preferred for visual description and sensing reliability. In this work, Yb2+ and Mn2+ ions co‐doped MgF2 with a fascinating ratiometric ML performance are successfully explored. ML color can be manipulated based on the distinct stress‐dependent ML intensity of the activators. Furthermore, a self‐activated orange persistent ML is observed even after the removal of the mechanics stimuli, allowing a delayed stress sensing with the memorized optical signals. Accordingly, a visualized stress sensing with the as‐explored ML composites using the ultraviolet curing 3D printing technique is demonstrated for structural mechanics. Herein, a feasible optical description of the loaded stress distribution in space for objects free from concerns with dimensions and geometrical shapes can be realized, benefiting the study of 3D structural mechanics, especially for complex structures.

Published: September 2023

AbstractSynergistic chemotherapy and photothermal therapy (PTT) have emerged as a promising anticancer paradigm to achieve expected therapeutic effects while mitigating side effects. However, the chemo/PTT combination therapy suffers from limited penetration depth, thermoresistance performance of tumor cells, and low drug bioavailability. Herein, multifunctional nanoparticles (BTP/DOX/2DG NPs) coloaded with near‐infrared region II (NIR‐II) light excitation donor–acceptor–donor (D–A–D) small molecules, doxorubicin (DOX), and 2‐deoxy‐d‐glucose (2‐DG) are developed for reinforced starvation/chemo/NIR‐II PTT combination therapy. The synthesized phenylboronic acid (PBA)‐modified water‐soluble D–A–D molecule (BBT‐TF‐PBA) not only exhibits high binding ability to DOX and 2‐DG through donor–acceptor coordination interactions PBA–diol bonds but also serves as a photoactive agent for NIR‐II fluorescence imaging, NIR‐II photoacoustic imaging, and NIR‐II PTT. Under the acidic and oxidizing conditions in the tumor microenvironment, donor–acceptor coordination interactions and PBA–diol bond are decomposed, simultaneously releasing DOX and 2‐DG from BTP/DOX/2DG NPs to achieve effective chemotherapy and starvation therapy. 2‐DG also effectively inhibits the expression of heat shock protein and further enhances NIR‐II PTT and chemotherapy efficiency. In vitro and in vivo experiments demonstrate the combination effect of BTP/DOX/2DG NPs for chemotherapy, NIR‐II PTT, and starvation therapy.

Published: September 2023

AbstractNeoadjuvant and adjuvant therapies have made significant progress in cancer treatment. However, tumor adjuvant therapy still faces challenges due to the intrinsic heterogeneity of cancer, genomic instability, and the formation of an immunosuppressive tumor microenvironment. Functional materials possess unique biological properties such as long circulation times, tumor‐specific targeting, and immunomodulation. The combination of functional materials with natural substances and nanotechnology has led to the development of smart biomaterials with multiple functions, high biocompatibilities, and negligible immunogenicities, which can be used for precise cancer treatment. Recently, subcellular structure‐targeting functional materials have received particular attention in various biomedical applications including the diagnosis, sensing, and imaging of tumors and drug delivery. Subcellular organelle‐targeting materials can precisely accumulate therapeutic agents in organelles, considerably reduce the threshold dosages of therapeutic agents, and minimize drug‐related side effects. This review provides a systematic and comprehensive overview of the research progress in subcellular organelle‐targeted cancer therapy based on functional nanomaterials. Moreover, it explains the challenges and prospects of subcellular organelle‐targeting functional materials in precision oncology. The review will serve as an excellent cutting‐edge guide for researchers in the field of subcellular organelle‐targeted cancer therapy.
Tuning AC Electrokinetic Flow to Enhance Nanoparticle Accumulation in Low‐Conductivity Solutions
Authors: Abdelghany Ahmed , Ichikawa Yoshiyasu , Motosuke Masahiro 
Published: September 2023

AbstractThis study presents a novel AC electrokinetics‐based microfluidic approach for nanoparticle trapping and accumulation in low‐conductive aqueous solutions. The concentration performance is systematically investigated by tuning the applied voltage and frequency, showing that AC electrothermal flow (ACET)‐induced vortex trapping provides a field strength‐dependent concentration enhancement and a high concentration factor. The findings reveal a substantial enhancement in the concentration of polystyrene nanoparticles with sizes of 100 nm. Specifically, a 16‐fold enrichment in the concentration is achieved compared with the initial concentration of the sample. In addition, the effectiveness of a high‐frequency AC voltage (50–150 kHz) versus a low‐frequency accumulation (1–20 kHz) for nanoparticle accumulation is compared and it is determined that at high frequencies, the trapped nanoparticles accumulate at a single area at the electrode gap, which differs from the low‐frequency accumulation observed in previous studies. The complex behavior of nanoparticle accumulation is analyzed, including the differences in the hydrodynamic flow patterns between AC electroosmosis and ACET flow. The proposed technique provides a powerful tool for the efficient and controllable manipulation of nanoparticles and contributes to a highly sensitive characterization of nanomaterials in low‐conductivity liquid samples in microfluidic systems through efficient particle trapping.

Published: September 2023

AbstractSingle‐use electrical systems represent the future of multiple fields such as diagnostic medical technologies, environmental studies, and biofuel manufacturing with significant advantages over conventional unrecyclable bulky systems that are partly disposable at best. Single‐use systems require miniaturized bio‐friendly energy sources that meet the recyclability or reusability requirement of the application without creating toxic waste. Herein, a storable, scalable, and single‐use electronics‐compatible bio‐battery that is designed and fabricated using completely reusable and recyclable components is developed. The battery is a dual‐in‐line package microbial fuel cell (DIP‐MFC) that can be activated on demand via the introduction of moisture through the anodic fluid chamber. The battery incorporates dormant bacteria cells on an abiotic stainless steel mesh that serves as the anode that attracts electrons being transferred from the biocatalyst. The DIP‐MFC uses the infestation of bacterial biofilm on a conductive anode to harness electrons and deliver electricity to selected circuit pins. A single DIP‐MFC continuously operates for 140 min with a maximum open circuit voltage of 0.55 V, which can be stacked and connected to match the power requirements of targeted electronics. The DIP nature of the proposed bio‐battery allows for simple integration of the MFC on conventional electronics boards through conductive pins.
Free‐Standing Tunnel‐Structured MnO2 Nanorods‐Doped with Nickel and Cobalt Cations as Bifunctional Electrocatalysts for Zn–Air Batteries

Published: September 2023

AbstractThe rational design of the electrocatalysts is paramount to alleviating the global energy and environment crisis. Despite a bright future of MnO2 shown in energy storage and conversion, the intrinsic low electrical conductivity glooms its application in electrocatalytic reactions like oxygen reduction/evolution reactions (ORR/OER). The doping strategy is applied to equip the self‐supported MnO2 with enhanced ORR/OER and zinc‐air battery performance. In this work, a class of free‐standing MnO2 nanorods arrays on carbon paper‐doped with either cobalt or nickel cations are engineered through a simple hydrothermal method. The substitutional doping by Co or Ni that partly replaces the Mn ions in the [MnO6] octahedra brings about the Jahn–Teller distortion that exhibits excellent catalytic performance for ORR and OER. Indeed, the ORR performance reveals that the doping resulted in more positive half‐wave potential (by >20 mV), higher limiting current densities, and an electron transfer number close to four. As for the OER, the doping not only decreases the overpotential at 10 mA cm−2 but also brings about an enhancement in the current density at 1.76 V six times greater than with the undoped MnO2 catalyst. An optimal concentration of 0.25 in the molar ratio Co/Mn or Ni/Mn is discovered based on the ORR/OER bifunctionality. Homemade rechargeable Zn–air aqueous batteries assembled with doped MnO2 deliver higher peak power density, higher specific capacity, lower charge voltage, lower charge/discharge voltage, and robust stability.
