School playgrounds found in painted environments have become death chambers for millions of innocent children who unknowingly ingest toxic metals. The objective of this study is to determine the levels of the heavy metals in paint chips from painted interior walls and indoor dust samples from 14 selected nursery schools in Nairobi County. The paint chips and indoor dust samples collected were digested using the Environmental Protection Agency method SW846 3050B then analyzed using Flame Atomic Absorption Spectrometry. Iron (Fe) had the highest concentrations in both the paint chip from interior walls and the indoor dust while Cadmium (Cd) had the lowest concentration followed by Chromium (Cr), Lead (Pb) and Zinc (Zn) respectively. 50% of the nursery schools had Lead (Pb) concentrations that exceeded the 90 µg/g limit set by KEBS. For Cadmium (Cd) and Chromium (Cr), the concentration in the nursery schools and the indoor dust was below the 200 µg/g used in Germany. Generally, the correlation between the various metal pairs for the samples analyzed showed a non-significant correlation with exception of Lead - Iron (Pb-Fe) and Chromium - Cadmium (Cr-Cd) for the indoor dust samples from pre-schools. The t-tests carried out show that levels of the heavy metals in the paint chip did not differ significantly with the levels in the indoor dust for nursery schools at 95% confidence level.

Published: September 2023

An experiment was conducted to determine the incidence of black point disease in wheat varieties with different locations caused by A. alternata fungal pathogens of wheat grain. Fresh seeds of popularly cultivated wheat varieties, preferably viz., GW 366, GW 496, Lok 1, and GW 1, were collected after harvesting season from the farmers’ fields of wheat growing areas of middle Uttarakhand viz., Sahaspur, Roorkee, Haridwar, and Dehradun. At least 50 samples were collected from each of the districts. Five primary samples were collected and mixed from the harvested seed lot to have composite samples. Working samples were prepared from composite samples by repeated halving method. The black point disease incidence might be due to the inherent boldness of the seeds. Florets remain more open in bold-seeded varieties, enhancing the chances of more seed infection during seed development. Moreover, low night temperatures during the flowering period, severe dew at the seed maturation stage, frequent and heavy crop irrigation, and excessive application of nitrogenous fertilizers may lead to a higher incidence of the black point disease. Besides, infected seeds reveal seed rot, necrosis, and shriveling. High humidity due to prolonged rainfall or heavy dew deposition during seed maturation favors the black point. As our research findings varied, GW366 is significantly the highest incidence of black point disease.

Published: September 2023

AbstractAuxetics are materials characterized by a negative Poisson's ratio (NPR), an uncommon mechanical behavior corresponding to a transversal deformation tendency opposite to the traditional materials. Here, the first example of a synthetic molecular auxetic polymer obtained by embedding a conformationally expandable cavitand as a crosslinker into a rigid polymer of intrinsic microporosity (PIM) is presented. The rigidity and microporosity of the polymeric matrix are pivotal to maximizing the expansion effect of the cavitand that, under mechanical stress, can assume two different conformations: a compact vase one and an extended kite form. The auxetic behavior and the corresponding NPR of the proposed material is predicted by a specific micromechanical model that considers the cavitand volume expansion ratio, the fraction of the cavitand crosslinker in the polymer, and the mechanical characteristics of the polymer backbone. The reversible auxetic behavior of the material is experimentally verified via the digital image correlation technique performed during the mechanical tests on films obtained by blending the auxetic crosslinked polymer with pristine PIM. Two specific control experiments prove that the mechanically driven conformational expansion of the cavitand crosslinker is the sole responsible for the observed NPR of the polymer.

Published: September 2023

AbstractHydrogen production from electrolytic water electrolysis is considered a viable method for hydrogen production with significant social value due to its clean and pollution‐free nature, high hydrogen production efficiency, and purity, but the anode oxygen evolution reaction (OER) process is complex and kinetically slow. Single‐atom catalysts (SACs) with 100% atom utilization and homogeneous active sites often exhibit high catalytic activity and are expected to be extensively applied. The catalytic performance of OER can be further improved by precise regulation of the structure through electronic effects, coordination environment, heteroatomic doping, and so on. In this review, the mechanisms of OER under different conditions are introduced, the latest research progress of SACs in the field of OER is systematically summarized, and then the effects of various structural regulation strategies on catalytic performance are discussed, and principles and ideas for the design of SACs for OER are proposed. In the end, the outstanding issues and current challenges in this field are summarized.

Published: September 2023

AbstractNumerous efforts for emulating organ systems comprised of multiple functional units have driven substantial advancements in bio‐realistic electronics and systems. The resistance change behavior observed in diffusive memristors shares similarities with the potential change in biological neurons. Here, the diffusive threshold switching phenomenon in Ag‐incorporated organometallic halide perovskites is utilized to demonstrate the functions of afferent neurons. Halide perovskites‐based diffusive memristors show a low threshold voltage of ≈0.2 V with little variation, attributed to the facile migration of Ag ions uniformly dispersed within the halide matrix. Based on the reversible and reliable volatile threshold switching, the memristors successfully demonstrate fundamental nociceptive functions including threshold firing, relaxation, and sensitization. Furthermore, to replicate the biological mechano‐nociceptive phenomenon at a system level, an artificial mechano‐nociceptive system is built by integrating a diffusive memristor with a force‐sensing resistor. The presented system is capable of detecting and discerning the detrimental impact caused by a heavy steel ball, effectively exhibiting the corresponding sensitization response. By further extending the single nociceptive system into a 5 × 5 array, successful stereoscopic nociception of uneven impulses is achieved in the artificial skin system through array‐scale sensitization. These results represent significant progress in the field of bio‐inspired electronics and systems.

Published: September 2023

AbstractTransition metal chalcogenides (TMCs) have attracted wide attentions as a class of promising material for both fundamental investigations and electronic applications due to their atomic thin thickness, dangling bond‐free surface, and excellent electronic properties. Specifically, TMCs show outstanding properties such as good thermal conductivity, robust mechanical properties, and extraordinary electronical characteristics, bestowing them utility in both fundamental research and applications. Recently, the development of post‐Moore electronics based on TMCs calls for their large‐size and single‐crystal growth. However, researchers about synthesis usually focus on controlling several growth parameters (such as growth temperature, flow rate, and time). Herein, it is reported that the chemical valence states of transition metal precursors play an important role in controlling the lateral size and crystal quality for TMCs. The study discusses the valence states‐dependent growth mechanism for WS2 and MoS2 from four factors: evaporation temperature, skipping of reaction steps, atomic binding energy of the precursors, and formation energy. In addition, the as‐grown WS2 and MoS2 nanoflakes exhibit good photoelectric response properties. For EuS, the growth results are obviously different by using EuBr3 and EuBr2 as precursors. The studies provide a unique perspective and also new knowledge to controllably grow large‐size and good crystal quality TMCs.

AbstractHerein, a copper‐catalyzed photoinduced [3+3] cycloaddition reaction of α‐acidic isocyanides with 2,5‐diaryltetrazoles is described. The reaction proceeded smoothly with high regioselectivity, affording a range of important 1,2,4‐triazines under mild conditions. The obtained 1,2,4‐triazines were converted into triazine alcohol, Weinreb amide and triazinone easily, which further illustrate the utility of this [3+3] cycloaddition process.

Published: September 2023

AbstractFlow chemistry has recently opened new chemistry windows thanks to the safer use of hazardous and sensitive reagents. Furthermore, flow procedures usually outperform their batch counterparts due to improved mass and heat transfer, offering a good opportunity for industrial application. Herein, a rapid Simmons‐Smith cyclopropanation flow process is presented. Taking advantage of the in situ production of the zinc carbenoid species, several olefins bearing aromatic rings of different electronic nature, aliphatic chains or heterocycles were smoothly cyclopropanated with a residence time of just 15 minutes. In addition, industrial applicability of the protocol is assured thanks to a successful 12‐mmol scale experiment, which represents a 3.59 grams per hour production of a selected example, and to the satisfactory synthesis of pharmaceutical drugs.

Published: September 2023

AbstractOwing to their mechanical resilience and non‐toxicity, titanium implants are widely applied as the major treatment modality for the clinical intervention against bone fractures. However, the intrinsic bioinertness of Ti and its alloys often impedes the effective osseointegration of the implants, leading to severe adverse complications including implant loosening, detachment, and secondary bone damage. Consequently, new Ti implant engineering strategies are urgently needed to improve their osseointegration after implantation. Remarkably, metalorganic frameworks (MOFs) are a class of novel synthetic material consisting of coordinated metal species and organic ligands, which have demonstrated a plethora of favorable properties for modulating the interfacial properties of Ti implants. This review comprehensively summarizes the recent progress in the development of MOF‐coated Ti implants and highlights their potential utility for modulating the bio‐implant interface to improve implant osseointegration, of which the discussions are outlined according to their physical traits, chemical composition, and drug delivery capacity. A perspective is also provided in this review regarding the current limitations and future opportunities of MOF‐coated Ti implants for orthopedic applications. The insights in this review may facilitate the rational design of more advanced Ti implants with enhanced therapeutic performance and safety.

AbstractDefects in perovskite films are still the dominant destroyer of both power conversion efficiency (PCE) and long‐term stability in perovskite solar cells (PSCs). As the most popular electron transport layer (ETL), TiO2 film is used in many PSCs to achieve high PCE. However, pristine TiO2 by itself is not sufficient as an ETL due to lattice mismatch, poor alignment of the energy level gap, and hysteresis of the PSC. Herein, ammonium sulfamate (AS), with desired NH4+ and S═O functional groups, is designed to modify the TiO2 surface and interface to improve the PCE of PSCs. It is found that the AS works like a seed layer for the perovskite deposition, and, in addition, it effectively forms a bridge between the TiO2 surface and the perovskite. As a result, PSCs are successfully fabricated with a champion power conversion efficiency of 24.78% with smaller hysteresis. The PSCs prepared using the AS‐modified TiO2 also show excellent stability, and the bare device without any encapsulation retains 96% of its initial PCE after 1056 h of ambient exposure at 25 °C and 25% relative humidity.
Children's rights violations: Parental corporal punishment under the microscope
Authors: Greeff Laetitia‐Ann 
Published: September 2023

AbstractWhen Australia ratified the United Nations Convention on the Rights of the Child (the Convention) in 1990, all children within its borders became entitled to the protection of the rights set out in the Convention. Children, thus, became rights holders. More than just human rights holders, they became children's rights holders. The Convention is the first international instrument to address the protection of children from violence directly. Corporal punishment (CP) is increasingly recognised internationally as physical abuse and a violation of children's rights. However, CP in the home is still legal in all Australian jurisdictions even though it violates several of the rights protected by the Convention. This contribution will examine Articles 2, 3(1), 5, 16, 19(1), 24(3) and 37(a) of the Convention to outline how parental CP undermines the legally binding obligations of the Convention by violating the rights espoused by these provisions. This article then calls for CP to be outlawed by all state and territory governments to adhere to the aim of the Convention that because of children's unique vulnerabilities, all their rights need to be protected, respected and promoted by those who ratified the Convention.

Published: September 2023

Abstract2D half‐metallic materials that have sparked intense interest in advanced spintronic applications are essential to the developing next‐generation nanospintronic devices. This study has adopted a first‐principles calculation method to predict the magnetic properties of intrinsic, Se‐doped, and biaxial strain tuning Cr2AsP monolayer. The Janus Cr2AsP monolayer is proven to be an intrinsic ferromagnetic (FM) semiconductor with an exchange splitting bandgap of 0.15 eV at the PBE+U level. Concentration‐dependent Se doping, such as Cr2AsSexP (x = 0.25, 0.50, 0.75), can regulate Cr2AsP from FM semiconductor to FM half‐metallicity. Specifically, the spin‐up channel crosses the Fermi level, while the spin‐down channel has a bandgap. More interestingly, the wide half‐metallic bandgaps and spin bandgaps make them have important implications for the preparation of spintronic devices. At last, it also explore the effect of biaxial strain from ‐14% to 10% on the magnetism of the Cr2AsP monolayer. There appears a transition from FM to antiferromagnetic (AFM) at a compressive strain of ‐10.7%, originating from the competition between the indirect FM superexchange interaction and the direct AFM interaction between the nearest neighboring Cr atoms. Additionally, when the compressive strain is ‐2% or the tensile strain is 6%, the semiconducting Cr2AsP becomes a half‐metallic material. These charming properties render the Janus Cr2AsP monolayer with great potential for applications in spintronic devices.

AbstractDie Erweiterung der chemischen Vielfalt von Peptid‐Makrozyklenbibliotheken für die Display‐Selektion ist wünschenswert, um ihr Potenzial zur Bindung an biomolekulare Ziele zu verbessern. Wir haben nun eine erhebliche Erweiterung durch die Einbeziehung eines großen, aromatischen helikalen Foldamers umgesetzt. Es wurde ein helikales aromatisches Foldamer identifiziert, welches eine Flexizym‐vermittelte tRNA‐Acylierung durchläuft und in der Lage ist, die ribosomale Translation mit Ausbeuten durchzuführen, die ausreichend hoch sind, um eine mRNA‐Display‐Selektion von makrozyklischen‐Foldamer‐Peptid‐Hybriden zu vollziehen. Ein hybrider Makrozyklus mit nanomolarer Affinität an C‐lobe der E6AP HECT‐Domäne wurde ausgewählt, der eine stark konvergente Peptidsequenz aufwies. Eine Kristallstruktur und Moleküldynamik‐Simulationen haben gezeigt, dass sowohl das Peptid als auch das Foldamer in einer faszinierenden, reziproken Heftklammer‐artigen Art helikal sind. Die starke Konvergenz der Reste könnte durch ihre Beteiligung an spezifischen Wechselwirkungen mit dem Zielprotein erklärt werden. Das Foldamer stabilisiert die Peptidhelix durch Heftklammern und durch Kontakte mit wesentlichen Resten. Diese Ergebnisse stellen insgesamt eine erhebliche Erweiterung des chemischen Raums dar, der für die Display‐Selektion zur Verfügung steht, und unterstreichen die möglichen Vorteile des Einfügens eines aromatischen Foldamers in einen Peptidmakrozyklus zum Zwecke der Proteinerkennung.
A Nanomedicine‐Enabled Ion‐Exchange Strategy for Enhancing Curcumin‐Based Rheumatoid Arthritis Therapy
Authors: Yang Jiacai , Yang Bowen , Shi Jianlin 
Published: September 2023

AbstractCurcumin (Cur) has been clinically used for rheumatoid arthritis treatment by the means of reactive oxygen species (ROS) scavenging and immune microenvironment regulation. However, this compound has a poor water solubility and moderate antioxidative activity, favoring no further broadened application. Metal complexes of curcumin such as zinc‐curcumin (Zn−Cur) features enhanced water solubilities, while copper‐curcumin (Cu−Cur) shows a higher antioxidant activity but lower solubility than Zn−Cur. Based on their inherent biological properties, this work proposes a nanomedicine‐based ion‐exchange strategy to enhance the efficacy of Cur for rheumatoid arthritis treatment. Copper silicate nanoparticles with hollow mesoporous structure were prepared to load water‐soluble Zn−Cur for constructing a composite nanomedicine, which can degrade in acidic microenvironment of arthritic region, releasing Cu2+ and Zn−Cur. Cu2+ then substitute for Zn2+ in Zn−Cur to form Cu−Cur with a significantly enhanced antioxidative effect, capable of efficiently scavenging ROS in M1 macrophages, promoting their transition to an anti‐inflammatory M2 phenotype. In addition, the silicate released after nanocarrier degradation and the Zn2+ released after ion exchange reaction synergistically promote the biomineralization of osteoblasts. This work provides a new approach for enhancing the antiarthritic effect of Cur via an ion‐exchange strategy.
