Pollutants emitted into the atmosphere, such as ozone, which raises temperature, contributes to climate change. This may have inverse effect on the local air quality. However, other Particulate Matter (PM) components can heat or cool the temperature. Weather and environmental pollution can cause headaches, heart disease, respiratory problems, acid rain, fever, and other symptoms that are harmful to both people and the environment. This research center on development of smart sensors to monitor our environment's exposure to weather and environmental contaminants. This was made possible by developing an interface between data collection and monitoring equipment that interfaced with a website and analysis software. The online portal records and analyzes the measured data from the monitoring device in accordance with the WHO (World Health Organization) standard. It also compares the measured data from various locations. The main microcontroller in this work is an Arduino UNO which helps in data collection; and the CoolTerm application which helps exchange data with hardware connected to serial ports with the microcontroller. The system monitors environmental changes such as temperature and precipitation. The data is displayed as graphical statistics on the web site's design in the form of web portal information.
Offices on the Federal Polytechnic Ile Oluji campus, in addition to the production powerhouse, are used to test the equipment. Each dataset was generated in three minutes and compared to the WHO standard. People who live near generators, according to the findings, face a greater risk to their health.

Seizures, intellectual incapacity, developmental delays, and behavioral issues are just a few of the warning symptoms. Like Skin problems, and lung and kidney problems. A hereditary mutation in one of two genes causes TSC.TSC1 and TSC2 are two distinct TSC types. The proteins hemartin and tuberin, which act as tumour suppressors and govern cell proliferation and differentiation, are produced by these genes. [1].
Background: Tuberous sclerosis complex (TSC) is a rare genetic disorder that affects 1 in every 6,000 to 1 in every 18,000 people. It's a life-threatening condition caused by the formation of benign tumors/lesions in several organs. Tumors can affect organ growth and/or function and are frequent in the brain, heart, skin, kidneys, and lungs. The number of organs affected, as well as the size of tumours inside each organ, varies greatly. As a result, the disease's symptoms are extremely variable and unexpected [2].

Published: December 2021

AbstractThe phase engineering of transition metal dichalcogenides (TMDs) is considered a promising strategy for promoting efficient catalysis, such as the hydrogen evolution reaction (HER). While theoretical studies predict the presence of catalytically active atomic sites at heterophase boundaries in TMDs, conventional bulk HER measurements are not able to precisely explore these 1D heterophase regions for HER. Here, one reports on active HER occurring at heterophase boundaries between the semiconducting 2H and metallic 1T’ phases in large‐scale MoTe2 grown via chemical vapor deposition. Microreactors are used to investigate the local HER at varying lengths of 1D heterophase boundaries, and the results are systematically compared with the HER performance at the pristine basal planes of MoTe2. Despite the small area ratio between the 1D heterophase boundary and the open region for local HER, a clear improvement in HER is observed with a turnover frequency of 317 s–1. The Kelvin probe force microscopy determines a surface potential difference of 50 mV across the heterophase boundary, which supports sharp band bending and local charge accumulation as the basis for the TMDs’ efficient electrochemical catalysis.

AbstractSingle‐atom electrocatalysts (SACs) toward hydrogen evolution reaction (HER) have been extensively studied owing to their high mass activity and atom utilization. Although platinum (Pt) based SACs have been reported frequently, optimizing the metal–support interaction to achieve low valence state Pt species is still a challenge. Here, the carbon supported α‐MoC1−x nanoparticles are used to anchor zero‐valent Pt single atoms (PtSA/α‐MoC1−x@C) as electrocatalyst for pH‐universal HER. The PtSA/α‐MoC1−x@C with optimized Pt loading of 0.75 wt% shows a low overpotential (21, 12, and 36 mV at 10 mA cm–2) and high turnover frequencies (27.00, 31.98, and 21.39 H2 s–1 at 100 mV) for HER under alkaline, acidic, and neutral electrolyte conditions. Experimental evidence combing density functional theory calculations confirm that the charge polarization leads to a zero‐valence state of Pt single atom and further optimized the adsorption/desorption energy of intermediates, further accelerating the reaction dynamics for HER.

AbstractThe relatively low operating voltage window is the main factor limiting the energy density of aqueous energy storage devices. The delicate design of heterostructured electrode materials can efficiently increase the intrinsic electrochemical performance through synergistic effects. For the first time, to broaden the voltage window of aqueous supercapacitors the synergistic effect between boroncarbonitrides (BCN) and built‐in electric field existing in heterostructures is designed to utilize. Based on this design concept, MnO/MnS@BCN electrode materials are synthesized, in which the synergistic effect can effectively strengthen the storage of electrolyte ions on the electrode surface, thus inhibiting the electrolysis of H2O and eventually broadening the voltage window of aqueous supercapacitor. In MnO/MnS@BCN‐based symmetrical supercapacitors, the voltage window of the device is extended from 1.2 V (single‐component) to 2 V, with the energy density enhanced to 75.0 W h kg−1. The strategy blazes an efficient and convenient path to broaden the intrinsic voltage window of transition metal oxide supercapacitors.

AbstractFine control of the chiral light–matter interaction at the nanoscale, by exploiting designed metamaterial architecture, represents a cutting‐edge craft in the field of biosensing, quantum, and classic nanophotonics. Recently, artificially engineered 3D nanohelices demonstrate programmable wide chiroptical properties by tuning materials and architecture, but fundamental diffractive aspects that are at the origin of chiral resonances still remain elusive. Here, a novel concept of a 3D chiral metacrystal, where the chiroptical properties are finely tuned by in‐plane and out‐of‐plane diffractive coupling, is proposed. Different chiral dipolar modes can be excited along the helix arms, generating far field optical resonances and radiation pattern with in‐plane side lobes, and suggesting that a combination of efficient dipole excitation and diffractive coupling matching controls the collective oscillations among the neighbor helices. The proposed concept of compact chiral metacrystal can be suitable for integration with quantum emitters and open perspectives in novel schemes of enantiomeric detection.

AbstractMetal phosphide nanoribbons are suitable building blocks for flexible photoelectronic microdevices due to the special electronic structure, large contact area, and excellent mechanical properties. In this work, single‐crystal copper phosphide nanoribbons (Cu3P NRs) are prepared topochemically from crystalline red phosphorus nanoribbons (cRP NRs) to retain the cRP morphology. The Cu3P NRs are used to construct flexible photoelectronic memristors on the ITO/PEN substrate with the native oxidized shell of Cu3P NRs serving as the charge trapping layer to modulate the resistance switching characteristics. The Cu3P NRs‐based memristors have outstanding nonvolatile memory properties in different mechanical bending states and different bending times. Optically and electrically modulated artificial synaptic functions are observed from the Cu3P NRs‐based memristors and owing to the memory backtracking function, pattern recognition is achieved with the Ag/Cu3P/ITO artificial synapse array. The topochemical synthesis method constitutes a universal approach to produce nanostructured compounds with an unusual morphology and specific crystalline orientation. The results also reveal that metal phosphides are excellent materials in memristors for future optoelectronic neuromorphic computing.

AbstractThe solvent acidolysis crystallization technique is utilized to grow mixed dimethylammonium/methylammonium lead tribromide (DMA/MAPbBr3) crystals reaching the highest dimethylammonium incorporation of 44% while maintaining the 3D cubic perovskite phase. These mixed perovskite crystals show suppression of the orthorhombic phase and a lower tetragonal‐to‐cubic phase‐transition temperature compared to MAPbBr3. A distinct behavior is observed in the temperature‐dependent photoluminescence properties of MAPbBr3 and mixed DMA/MAPbBr3 crystals due to the different organic cation dynamics governing the phase transition(s). Furthermore, lateral photodetectors based on these crystals show that, at room temperature, the mixed crystals possess higher detectivity compared to MAPbBr3 crystals caused by structural compression and reduced surface trap density. Remarkably, the mixed‐crystal devices exhibit large enhancement in their detectivity below the phase‐transition temperature (at 200 K), while for the MAPbBr3 devices only insignificant changes are observed. The high detectivity of the mixed crystals makes them attractive for visible‐light communication and for space applications. The results highlight the importance of the synthetic technique for compositional engineering of halide perovskites that governs their structural and optoelectronic properties.

AbstractMachine learning (ML) holds potential to predict hunger crises before they occur. Yet, ML models embed crucial choices that affect their utility. We develop a prototype model to predict food insecurity across three countries in sub‐Saharan Africa. Readily available data on prices, assets, and weather all influence our model predictions. Our model obtains 55%–84% accuracy, substantially outperforming both a logit and ML models using only time and location. We highlight key principles for transparency and demonstrate how modeling choices between recall and accuracy can be tailored to policy‐maker needs. Our work provides a path for future modeling efforts in this area.
