Authors: Qu Menglong , Guo Yani , Cai Yahan , Nie Zhengwei , Zhang Cheng 
Published: May 2024

AbstractThe widespread use of plastics, especially polyolefin including polyethylene and polypropylene, has led to severe environmental crises. Chemical recycling, a promising solution for extracting value from plastic waste, however, is underutilized due to its complexity. Here, a simple approach, silicone‐assisted direct laser writing (SA‐DLW) is developed, to upgrade polyolefin plastic waste into multifunctional porous graphene, called laser‐induced graphene (LIG). This method involves infiltrating polyolefins with silicone, which retards ablation during the DLW process and supplies additional carbon atoms, as confirmed by experimental and molecular dynamic results. A remarkable conversion yield of 38.3% is achieved. The upgraded LIG exhibited a porous structure and high conductivity, which is utilized for the fabrication of diverse energy and electronic devices with commendable performance. Furthermore, the SA‐DLW technique is versatile for upgrading plastic waste in various types and forms. Upgrading plastic waste in the form of fabric has significantly simplified pre‐treatment. Finally, a wearable flex sensor is fabricated on the non‐woven fabric of a discarded medical mask, which is applied for gesture monitoring. This work offers a simple but effective solution to upgrade plastic waste into valuable products, contributing to the mitigation of environmental challenges posed by plastic pollution.

Published: May 2024

AbstractThe exploration of 2D materials has captured significant attention due to their unique performances, notably focusing on graphene and hexagonal boron nitride (h‐BN). Characterized by closely resembling atomic structures arranged in a honeycomb lattice, both graphene and h‐BN share comparable traits, including exceptional thermal conductivity, impressive carrier mobility, and robust pi–pi interactions with organic molecules. Notably, h‐BN has been extensively examined for its exceptional electrical insulating properties, inert passivation capabilities, and provision of an ideal ultraflat surface devoid of dangling bonds. These distinct attributes, contrasting with those of h‐BN, such as its conductive versus insulating behavior, active versus inert nature, and absence of dangling surface bonds versus absorbent tendencies, render it a compelling material with broad application potential. Moreover, the unity of such contradictions endows h‐BN with intriguing possibilities for unique applications in specific contexts. This review aims to underscore these key attributes and elucidate the intriguing contradictions inherent in current investigations of h‐BN, fostering significant insights into the understanding of material properties.

AbstractManganese oxide‐based aqueous zinc‐ion batteries (ZIBs) are attractive energy storage devices, owing to their good safety, low cost, and ecofriendly features. However, various critical issues, including poor conductivity, sluggish reaction kinetics, and unstable structure still restrict their further development. Oxygen defect engineering is an effective strategy to improve the electrochemical performance of manganese oxides, but challenging in the accurate regulation of oxygen defects. In this work, an effective and controllable defect engineering strategy‐controllable electrochemical lithium‐ion intercalation – is proposed to tackle this issue. The incorporation of lithium ions and oxygen defects can promote the conductivity, lattice spacing, and structural stability of Mn2O3 (MO), thus improving its capacity (232.7 mAh g−1), rate performance, and long‐term cycling stability (99.0% capacity retention after 3000 cycles). Interestingly, the optimal ratio of intercalated lithium‐ion varies at different temperature or mass‐loading of MO, which provides the possibility to customize diverse ZIBs to meet different application conditions. In addition, the fabricated ZIBs present good flexibility, superior safety, and admirable adaptability under extreme temperatures (−20–100 °C). This work provides an inspiration on the structural customization of metal oxide nanomaterials for diverse ZIBs, and sheds light on the construction of future portable electronics.

Published: May 2024

AbstractInorganic solid‐state electrolytes have attracted enormous attention due to their potential safety, increased energy density, and long cycle‐life benefits. However, their application in solid‐state batteries is limited by unstable electrode‐electrolyte interface, poor point‐to‐point physical contact, and low utilization of metallic anodes. Herein, interfacial engineering based on sodium (Na)‐conductive polymeric solid‐state interfacial adhesive is studied to improve interface stability and optimize physical contacts, constructing a robust organic‐rich solid electrolyte interphase layer to prevent dendrite‐induced crack propagation and security issues. The interfacial adhesive strategy significantly increases the room‐temperature critical current density of inorganic Na‐ion conductors from 0.8 to 3.2 mA cm−2 and markedly enhances the cycling performance of solid‐state batteries up to 500 cycles, respectively. Particularly, the Na3V2(PO4)3‐based full solid‐state batteries with high cathode loading of 10.16 mg cm−2 also deliver an excellent cycling performance, further realizing the stable operation of solid‐state laminated pouch cells. The research provides fundamental perspectives into the role of interfacial chemistry and takes the field a step closer to realizing practical solid‐state batteries.

AbstractThe high theoretical energy density (2600 Wh kg−1) and low cost of lithium–sulfur batteries (LSBs) make them an ideal alternative for the next‐generation energy storage system. Nevertheless, severe capacity degradation and low sulfur utilization resulting from shuttle effect hinder their commercialization. Herein, Single‐atom Ru‐doped 1T/2H MoS2 with enriched defects decorates V2C MXene (Ru–MoS2/MXene) produced by a new phase‐engineering strategy employed as sulfur host to promote polysulfide adsorption and conversion reaction kinetics. The Ru single atom‐doped adjusts the chemical environment of the MoS2/MXene to anchor polysulfide and acts as an efficient center to motivate the redox reaction. In addition, the rich defects of the MoS2 and ternary boundary among 1T/2H MoS2 and V2C accelerate the charge transfer and ion movements for the reaction. As expected, the Ru–MoS2/MXene/S cathode‐based cell exhibits a high‐rate capability of 684.3 mAh g−1 at 6 C. After 1000 cycles, the Ru–MoS2/MXene/S cell maintains an excellent cycling stability of 696 mAh g−1 at 2 C with a capacity degradation as low as 0.02% per cycle. Despite a high sulfur loading of 9.5 mg cm−2 and a lean electrolyte‐to‐sulfur ratio of 4.3, the cell achieves a high discharge capacity of 726 mAh g−1.

AbstractTwo‐dimensional (2D) materials exhibit the potential to transform semiconductor technology. Their rich compositional and stacking varieties allow tailoring materials’ properties toward device applications. Monolayer to multilayer gallium sulfide (GaS) with its ultraviolet band gap, which can be tuned by varying the layer number, holds promise for solar‐blind photodiodes and light‐emitting diodes as applications. However, achieving commercial viability requires wafer‐scale integration, contrasting with established, limited methods such as mechanical exfoliation. Here the one‐step synthesis of 2D GaS is introduced via metal–organic chemical vapor deposition on sapphire substrates. The pulsed‐mode deposition of industry‐standard precursors promotes 2D growth by inhibiting the vapor phase and on‐surface pre‐reactions. The interface chemistry with the growth of a Ga adlayer that results in an epitaxial relationship is revealed. Probing structure and composition validate thin‐film quality and 2D nature with the possibility to control the thickness by the number of GaS pulses. The results highlight the adaptability of established growth facilities for producing atomically thin to multilayered 2D semiconductor materials, paving the way for practical applications.

AbstractSnOx has received great attention as an electrocatalyst for CO2 reduction reaction (CO2RR), however; it still suffers from low activity. Moreover, the atomic‐level SnOx structure and the nature of the active sites are still ambiguous due to the dynamism of surface structure and difficulty in structure characterization under electrochemical conditions. Herein, CO2RR performance is enhanced by supporting SnO2 nanoparticles on two common supports, vulcan carbon and TiO2. Then, electrolysis of CO2 at various temperatures in a neutral electrolyte reveals that the application window for this catalyst is between 12 and 30 °C. Furthermore, this study introduces a machine learning interatomic potential method for the atomistic simulation to investigate SnO2 reduction and establish a correlation between SnOx structures and their CO2RR performance. In addition, selectivity is analyzed computationally with density functional theory simulations to identify the key differences between the binding energies of *H and *CO2−, where both are correlated with the presence of oxygen on the nanoparticle surface. This study offers in‐depth insights into the rational design and application of SnOx‐based electrocatalysts for CO2RR.

AbstractNa3V2(PO4)3 is a promising high‐voltage cathode for aqueous zinc‐ion batteries (ZIBs) and organic sodium‐ion batteries (SIBs). However, the poor rate capability, specific capacity, and cycling stability severely hamper it from further development. In this work, Na3V2(PO4)3 (NVP) with vanadium nitride (VN) quantum dots encapsulated by nitrogen‐doped carbon (NC) nanoflowers (NVP/VN@NC) are manufactured as cathode using in situ nitridation, carbon coating, and structural adjustment. The outer NC layer increases the higher electronic conductivity of NVP. Furthermore, VN quantum dots with high theoretical capacity not only improve the specific capacity of pristine NVP, but also serve as abundant “pins” between NVP and NC to strengthen the stability of NVP/VN@NC heterostructure. For Zn‐ion storage, these essential characteristics allow NVP/VN@NC to attain a high reversible capacity of 135.4 mAh g−1 at 0.1 A g−1, and a capacity retention of 91% after 2000 cycles at 5 A g−1. Meanwhile, NVP/VN@NC also demonstrates to be a stable cathode material for SIBs, which can reach a high reversible capacity of 124.5 mAh g−1 at 0.1 A g−1, and maintain 92% of initial capacity after 11000 cycles at 5 A g−1. This work presents a feasible path to create innovative high‐voltage cathodes with excellent reaction kinetics and structural stability.

AbstractWetlands, refer to the confluence with regards to land and water having a rich biological diversity with multiple purpose. As per the Ramsar Convention, framed in August 2002, East Kolkata Wetlands have been considered to be of global significance. Although inappropriate supervision of these wetlands, has led to the gradual deterioration of this wetland. In this present study, the soil sample was collected from these reclaimed agricultural wetlands of Chowbaga area, of East Kolkata areas with coordinates of 22.5296°N, 88.4207°E. The predominant or lingering bacterial flora was isolated from the soil surrounding the rhizospheric region of Cucurbita sp. and Zea mays and their plant growth promotion properties of the lingering bacterial flora were analyzed. These plant growth promoting rhizobacteria (PGPR) included some species of Bacillus sp. that could augment plant growth by different methodologies like nitrogen fixation, phosphate solubilization, phytohormone synthesis, and siderophore production. One of the bacterial isolates DPP(C) showed highest ability of siderophore production of 37.89% at 48 hours, whereas DCP(A) showed better capability in IAA production of 56.785 μg/mL than rest of the bacterial isolates. These reclaimed agricultural lands were found to have very high quantities of heavy metals, especially lead. All the bacterial isolates, were found to have great potential in lead mitigation, whereby they could adsorb up to 8.28% of lead. Some studies have shown the capability of microbial degradation for bioremediation of organic forms of lead and thereby can be removed from agricultural field for longer period of time. The prospective potential use of PGPR has gradually escalated, since it is one of the best substitutes against the constant usage of chemical fertilizers as well as pesticides. The use of these PGPR is one of the most reliable methods for ensuring sustainable agriculture. Furthermore, in future, the PGPR population will be correlated with the nutrient availability and productivity of the plants.

Computational exploration of strain‐induced in the physical characteristics of inverse‐spinel Li2RuSn4 via density functional theory
Authors: Jabar Abderrahim , Idrissi Samira , Bahmad Lahoucine 
Published: May 2024

AbstractIn this research, the physical properties of the inverse‐spinel Li2RuSn4 compound have been investigated using ab‐initio computational methods within the Wien2k package. The LSDA+mBJ approach was employed to determine the exchange‐correlation potential. The compound was found to exhibit metallic and nonmagnetic behavior in terms of electronic properties. The optical characteristics have been analyzed along xx, yy, and zz directions, revealing an increase in absorption coefficient with rising photon energies, culminating in a prominent peak in the UV domain. The higher intensity in xx and yy directions signify stronger absorption along these axes. The thermodynamic properties of Li2RuSn4, including volume, Debye temperature, Grüneisen parameter, volumetric thermal expansion coefficient, and lattice thermal conductivity were examined. The Debye temperature was found to rise proportionally with tensile strain and decrease with temperature, suggesting that dilatation strain can enhance the mechanical and thermal stability of the compound. The thermoelectric analysis revealed n‐type behavior, with negative Seebeck coefficient values. This research offers valuable insights into the properties of Li2RuSn4, contributing to the understanding of its potential applications.

Published: May 2024

AbstractThe mountains of Central Asia support many environmental functions and ecosystem services. The mountain environments and their services are affected by climate change and climate change adaptation (CCA) actions are required to increase resilience of regional communities. This paper is a systematic review of the English and Russian‐language literature published between 2013 (IPCC AR5) and May 2021 (IPCC AR6) focusing on CCA in the Central Asian mountains. In all, 52 publications have been reviewed. Criteria defining incremental and transformative adaptation were established and the reviewed studies were assigned to one of these approaches. The relatively low number of publications shows that the extent of CCA knowledge represented in academic literature is limited in comparison to other mountainous regions. There is a disparity between the growing body of publications addressing climate change and limited and decreasing number of academic publications focusing on adaptation in the region. Only 11 publications reported transformative adaptation actions. Most of the reviewed papers (55%) focus on water resources and future water availability; 15% focus on land degradation, 10% on changes in vertical zonation of plant species, 7% on loss of plant species, 3% on impacts of hazardous events, and 10% on multiple impacts of climate change. The awareness of the importance of CCA among the regional actors should be improved through closer collaboration between researchers, international organizations focusing on sustainable development and adaptation which have recently become more active in the region, practitioners, and local communities and co‐production of knowledge on the development and implementation of CCA.This article is categorized under:

AbstractBackgroundpathological complete response (pCR) is achieved in 10%–30% of rectal cancer patients following neoadjuvant chemoradiotherapy and surgery. Residual mucosal abnormalities, which make patients ineligible for nonoperative management, may not be an accurate indicator of the pCR. The purpose of this study was to report the gross findings of rectal cancer patients with pathological complete responses.MethodsThis study was conducted at Tehran University of Medical Sciences, Tehran, Iran. A total of 130 patients with rectal adenocarcinoma, treated by neoadjuvant chemoradiotherapy, followed by surgical resection between March 2007, and March 2017, with a surgical pathology report of pCR, were included. Patients' demographics and pretreatment tumor characteristics were collected from the medical records. Data regarding residual mucosal abnormalities were extracted from postoperative surgical pathology reports. Abnormal findings were reported as "ulcer" or " non‐ulcerative lesion".ResultsOne hundred and fifteen patients (88.5%; 95% CI: 81.7%–93.4%) had at least one abnormal finding in the gross examination, including ulcer or non‐ulcerative lesion (any mucosal abnormalities other than ulcers, including polyps, telangiectasia, etc.). Patients with higher‐stage tumors had a higher chance of having an ulcerative lesion (p = 0.05). Younger patients tended to have deeper layers of involvement (p = 0.013). Patients with different gross findings were not significantly different regarding baseline characteristics, except for the pretreatment stage, where patients with a higher stage had higher odds of having ulcerative lesions.ConclusionsMost rectal cancer patients achieving a pCR exhibit abnormalities on gross examination. The higher pretreatment stages were significantly associated with gross abnormalities especially ulcers.
