Published: June 2024

AbstractRecently, atmospheric water harvesting (AWH) based on hygroscopic salt on an inorganic or organic carrier has attracted great attention because of its significant potential applications in the environment. The major technical challenges for practical applications are how to prevent the leakage of hygroscopic salt while achieving a high capacity for sorption of atmospheric water and a high sorption rate. Additionally, techniques for converting sorbed water (in the form of a lithium chloride (LiCl) solution) into clean water need to be developed. Here, a novel method for continuous atmospheric water harvesting, leveraging LiCl@PHEA hydrogels is introduced. Synthesized via one‐step UV polymerization in saturated LiCl solutions, these hydrogels exhibit remarkable air distension ability (>60 times), achieving high water sorption efficiency (11.18 gg−1 at 90% relative humidity in 30 min) with over 90 wt.% salt content and no leakage. This water collection system integrates a porous evaporator and a 3D‐printed silica substrate, ensuring an extraordinarily high evaporation rate (>11 kgm−2 h−1 under sunlight) and efficient water transmission. A prototype based on this achieves a record‐breaking collection rate of over 5 kgm−2 h−1, enabling large‐scale efficient atmospheric water harvesting. Additionally, continuous hydrogen production through electrolysis using the collected water (< 5 ppm of salts) is demonstrated.

AbstractPhoto‐activated therapeutic strategies have great potential for preventing bacterial infections, especially infections associated with drug‐resistant bacteria, owing to their minimal tendency to induce drug resistance. A single course of light‐based therapeutics may lack the desired efficacy. The use of a high‐power excitation source or high doses of photo‐activated agents may cause excessive damage to normal tissues. Herein, a multimodal antibacterial platform that combines photodynamic and photothermal therapies has been developed. The fluoro‐substituted coumarin compound (TCF) and Prussian blue nanocubes (PB NCs) are integrated into the bacterial cellulose (BC) to form a versatile wound dressing (BC‐TCF‐PB). Fluoro‐substitution in TCF is found to enhance its production of 1O2 by boosting the intersystem crossing. Furthermore, the generated 1O2 can react with the thiocarbonyl group in TCF to form a highly emissive product. In situ self‐reporting fluorescence of TCF allows for the visualization of 1O2 generation, and assessment of the bacterial eradication. In addition, the BC‐TCF‐PB platform exhibits synergistic antibacterial effects on the methicillin‐resistant Staphylococcus aureus (MRSA), and provides an effective solution for infection control and wound healing. Thus, the BC‐TCF‐PB dressing, with self‐reporting of the reactive biocide generation in situ, has offered valuable insights into effective wound management.

AbstractThe field of spintronics has seen a surge of interest in altermagnetism due to novel predictions and many possible applications. MnTe is a leading altermagnetic candidate that is of significant interest across spintronics due to its layered antiferromagnetic structure, high Neel temperature (TN ≈ 310 K) and semiconducting properties. The results on molecular beam epitaxy (MBE) grown MnTe/InP(111) films are presented. Here, it is found that the electronic and magnetic properties are driven by the natural stoichiometry of MnTe. Electronic transport and in situ angle‐resolved photoemission spectroscopy show the films are natively metallic with the Fermi level in the valence band and the band structure is in good agreement with first‐principles calculations for altermagnetic spin‐splitting. Neutron diffraction confirms that the film is antiferromagnetic with planar anisotropy and polarized neutron reflectometry indicates weak ferromagnetism, which is linked to a slight Mn‐richness that is intrinsic to the MBE‐grown samples. When combined with the anomalous Hall effect, this work shows that the electronic response is strongly affected by the ferromagnetic moment. Altogether, this highlights potential mechanisms for controlling altermagnetic ordering for diverse spintronic applications.

Published: June 2024

AbstractThe conversion of CO2 into formate through electrochemical methods is emerging as an elegant approach for industrial‐scale CO2 utilization in the near future. Although Bismuth (Bi)‐based materials have shown promise thank to their excellent selectivity, their limited reactivity remains a challenge. Herein, this study demonstrates a significant enhancement in the CO2‐to‐formate efficiency of Bi by incorporating ruthenium (Ru) atomic species. Ru single atom doped Bi exhibited a nearly twofold higher partial current density compared with pure Bi and Ru clusters doped Bi, while over 95% Faradaic efficiency (FE) is maintained. Through comprehensive investigations using a combined approach of electrochemical techniques, operando spectroscopy, and theoretical calculations, this study elucidates that the presence of Ru single atom promotes H2O dissociation and H* migration to Bi sites for CO2‐to‐formate conversion by significantly reducing the energy barrier via a H* spillover path. Besides, it is constructed Ru–Bi bridge sites for efficient CO2 hydrogenation via a non‐spillover path, which served as the major mechanism for CO2‐to‐formate conversion in Ru single atom doped Bi.

Published: June 2024

AbstractHydrogel‐based flexible solid‐state supercapacitors (SSCs) hold great promise for wearable electronics, yet significant challenges persist in simultaneously achieving excellent mechanical properties, high ionic conductivity, outstanding electrochemical properties, and wide operating temperature ranges. Here, this study presents a straightforward method for synthesizing dual crosslinked polyvinyl alcohol‐polyimide (PVA‐PI) organohydrogels via a simple one‐pot synthesis followed by a freezing‐thawing process. The controlled dual crosslinked networks with significanonetly different crosslinking densities and robust intermolecular hydrogen bonding interactions facilitated by the macromolecular crosslinker of PI, endow the organohydrogels with both high mechanical properties and ionic conductivity. Furthermore, SSCs based on PVA‐PI organohydrogels are fabricated, which can exhibit outstanding electrochemical performance at temperatures ranging from −40 to 80 °C. Specifically, the energy density reaches 16.7 µWh cm−2 even at −40 °C under a power density of 410.0 µW cm−2. These SSCs also show excellent performance stability under various deformations, such as bending and compression, alongside exceptional long‐term cycling stability (over 10 000 cycles) with high capacitance retention from −40 to 50 °C. The synthesis strategy, along with a robust mechanism for enhancing mechanical properties of hydrogels, demonstrated in this study offers insights for the development of strong hydrogels/organohydrogels with broad temperature adaptability for soft electronic applications.

AbstractThe development of projection‐based stereolithography 3D printing techniques has provided a powerful approach to fabricate millimeter scale functional devices with complex structures. However, the current processes face challenges in frequent switching between multiple materials or processes, resulting in low efficiency and accuracy during the fabrication of bifunctional devices. To address these challenges, chemical deposition is utilized to modify graphene nanoplatelets (GNs) with Fe3O4 magnetic particles and incorporate them into the photosensitive resin, resulting in the development of a novel bifunctional printing material with magnetic and locally conductive properties. Furthermore, the localized conductivity of devices is controlled by an electric‐field‐assisted alignment process of the magnetic GNs (mGNs) during the printing process. Herein, this single‐material projection‐based stereolithography allows for the simultaneous fabrication of magnetic and locally conductive millimeter scale bifunctional devices without switching between multiple materials or processes. A magnetically driven circuit switch and signal coding gear are fabricated as demonstrations. This work significantly improves the efficiency and accuracy of fabricating millimeter scale bifunctional devices, thereby facilitating their application in the fabrication of miniaturized and integrated devices.

AbstractCopper‐based halide perovskite, as an ideal alternative to lead‐based halide perovskite, has attracted much attention in many applications owing to its earth‐abundant element, non‐toxicity, and excellent optical properties. In this report, magnetic Mn‐incorporated lead‐free copper halide perovskite (Cs3Cu2Br5) nanocrystal (NC) is for the first time designed and prepared using a one‐pot hot‐injection route, resulting in a new emission band at ≈540 nm accompanied with self‐trapped exciton (STE) emission centered at ≈445 nm from Cs3Cu2Br5 NC. In situ X‐ray photoelectron spectroscopy and in situ kelvin probe force microscopy (KPFM) confirm that the Mn2+ incorporation causes efficient electron–hole separation and extended charge lifetime in Mn‐doped Cs3Cu2Br5 NC, which exhibits significantly raised selectively photocatalytic biomass conversion coupled with obviously enhanced H2O2 evolution. With an external magnetic field, the spin‐polarized electrons in Mn‐doped Cs3Cu2Br5 NC arouses reduced charge recombination and more available electrons/holes for surface redox reaction, further raising the photocatalytic performance. This is confirmed by in situ steady‐state/transient‐state photoluminescence (PL) spectroscopy, in situ transient photocurrent measurement, and in situ electrochemical impedance spectroscopy with external magnetic field. In situ electron paramagnetic resonance (EPR) spectra reveal the radical‐involved reaction pathway for biomass conversion. This research exhibits the great potential of spin‐polarization‐enhanced photocatalysis by an external magnetic field without additional energy consumption.

Published: June 2024

AbstractLipid vesicles are widely used for drug and gene delivery, but their structural instability reduces in vivo efficacy and requires specialized handling. To address these limitations, strategies like lipid cross‐linking and polymer–lipid conjugation are suggested to enhance stability and biological efficacy. However, the in vivo metabolism of these altered lipids remains unclear, necessitating further studies. A new stabilization technique without chemical modification is urgently needed. Here, a bio‐mimetic approach for fabricating robust multilamellar lipid vesicles to enhance in vivo delivery and stabilization of protein antigens is presented. This method leverages 1‐O‐acylceramide, a natural skin lipid, to facilitate the self‐assembly of lipid nanovesicles. Incorporating 1‐O‐acylceramide, anchoring lipid bilayers akin to its role in the stratum corneum, provides excellent stability under environmental stresses, including freeze–thaw cycles. Encapsulating ovalbumin as a model antigen and the adjuvant monophosphoryl lipid A demonstrates the vesicle's potential as a nanovaccine platform. In vitro studies show enhanced immune responses with both unilamellar and multilamellar vesicles, but in vivo analyses highlight the superior efficiency of multilamellar vesicles in inducing higher antibody and cytokine levels. This work suggests ceramide‐induced multilamellar lipid vesicles as an effective nanovaccine platform for enhanced antigen delivery and stability.

AbstractCartilage defects trigger post‐traumatic inflammation, leading to a catabolic metabolism in chondrocytes and exacerbating cartilage degradation. Current treatments aim to relieve pain but fail to target the inflammatory process underlying osteoarthritis (OA) progression. Here, a human cartilage microtissue (HCM) nanoenabled with ibuprofen‐loaded poly(lactic‐co‐glycolic acid) nanoparticles (ibu‐PLGA NPs) is 4D‐bioprinted to locally mitigate inflammation and impair nerve sprouting. Under an in vitro inflamed environment, the nanoenabled HCM exhibits chondroprotective potential by decreasing the interleukin (IL)1β and IL6 release, while sustaining extracellular matrix (ECM) production. In vivo, assessments utilizing the air pouch mouse model affirm the nanoenabled HCM non‐immunogenicity. Nanoenabled HCM‐derived secretomes do not elicit a systemic immune response and decrease locally the recruitment of mature dendritic cells and the secretion of multiple inflammatory mediators and matrix metalloproteinases when compared to inflamed HCM condition. Notably, the nanoenabled HCM secretome has no impact on the innervation profile of the skin above the pouch cavity, suggesting a potential to impede nerve growth. Overall, HCM nanoenabled with ibu‐PLGA NPs emerges as a potent strategy to mitigate inflammation and protect ECM without triggering nerve growth, introducing an innovative and promising approach in the cartilage tissue engineering field.

AbstractThere is an increasing interest in the exploration of non‐Nickel cathode materials for steam electrolysis in solid oxide electrolysis cells (SOEC) for green hydrogen production with high Faradaic efficiencies. Ferrite‐based ceramic materials have drawn a lot of attention in this regard due to their appreciable mixed ionic electronic conductivity. This work aims to explore a ferrite‐based mixed ionic electronic conductor electrode for symmetrical SOEC that can contribute significantly to simplifying the manufacturing processes. A composite of silver (Ag) and A‐site deficient lanthanum strontium cobalt ferrite ((La0.60Sr0.40)0.95Co0.20Fe0.80O3‐x), is studied for steam electrolysis in a yttria stabilized zirconia electrolyte‐supported symmetrical tubular solid oxide cell. A considerable current density of 250 mA cm−2 is obtained at 1.5 V and 800 °C in a Helium‐Steam atmosphere (50% humidified) with a corresponding polarization resistance as low as 0.15 Ω‐cm2. The polarization resistance is comparable to a number of electrodes reported in the literature for steam electrolysis. However, a 10% drop in current density is observed during the first 20 h of electrolysis at 1.5 V and 800 °C in a Helium‐Steam atmosphere (50% humidified), but no further drop is encountered during the next 46 h of continuous operation.

Published: June 2024

AbstractDegradation of organic pollutants in wastewater is crucial for global environmental health. Semiconductor‐based photocatalytic technologies have received widespread attention due to their ability to directly utilize solar energy, produce no secondary pollution, and offer long‐lasting functionality. However, current photocatalyst preparation technologies face issues such as complex manufacturing processes, low efficiency, and the need for various additives. Therefore, this work proposes a simple and eco‐friendly method to in‐situ growth of reduced graphene oxide (rGO) onto magnesium oxide (MgO), forming a MgO@rGO core‐shell structured photocatalyst through CO2 thermal reaction process. After systematic study, the incorporation of rGO onto MgO core greatly extends the light absorption range from ultraviolet (UV) to visible wavelength, enabling substantially enhanced light capture and photoexcited carriers. Additionally, the core‐shell heterojunction with a built‐in electric field at the interface between MgO and rGO facilitates distinctly the separation and migration of the photogenerated charges. This structure‐induced synergistic effect boosts the photocatalytic performance of MgO@rGO by a factor of 1.7, 4.1, 41.8, and 6.4, compared with MgO (stripped), MgO (pure), rGO, and commercially used TiO2, respectively. This work provides a simple and effective strategy for designing advanced functional nanocomposites to address environmental problems.
Repurposing Discarded Electric Geyser Scaling Waste for Biochar Modification and Insights into Removal of Nitrate and Fluoride from Drinking Water
Authors: Verma Vartika , Sharma Yogesh Chandra 
Published: June 2024

AbstractThis research explores the potential of use of waste scaling deposition from electric geysers (EGWS) to synthesize calcium oxide and address fluoride and nitrate contamination in water. The study adopts a circular economy framework by utilizing the synthesized calcium oxide to modify corn cob biochar through ball‐milling, creating a cost‐effective and environmentally sustainable adsorbent. The adsorbent is characterized and pHpzc analysis of CaO@CBC indicates sustained high adsorption capacities for nitrate and fluoride across a broad pH range (2–11). The adsorption kinetics follow a pseudo‐second‐order model, indicating chemisorption mechanisms. The Langmuir isotherm model fits well, showing high maximum adsorption capacities of 18.36 mg g−1 for fluoride and 19.27 mg g−1 for nitrate, surpassing those reported for other materials. Thermodynamic studies indicate that the uptake reactions of fluoride and nitrate are spontaneous and exothermic. Results from pH studies, XPS analysis, and FTIR offer insights into the adsorption mechanism by suggesting electrostatic attraction, inner‐sphere complexation, and ion exchange. The research establishes the efficacy of CaO‐impregnated biochar derived from electric geyser waste in removing fluoride and nitrate, offering a sustainable solution for water pollution. This work breakthroughs the development of efficient and eco‐friendly adsorbents for water treatment, aligning with the principles of a circular economy.

AbstractConstructing heterostructure is a promising strategy to enhance photocatalytic performance. Here, a cyano and carbon dots/polypyrrole (CDs/PPy) co‐modified carbon nitride (CPKCN) heterostructure is constructed for photocatalytic H2O2 generation. It is interestingly found that the intermediates formed during the oxidation polymerization of pyrrole can be the potential electron trapping sites and reactive sites. In addition, the localized photoheat produced by CDs/PPy also plays an active role in improving photocatalytic activity. Moreover, the addition of CDs/PPy leads to a higher negative zeta potential of CPKCN, which is favorable for the attraction of the sample surface to H+. These features, plus the positive effect of cyano groups, collectively boost the charge transfer and improve the selectivity of two‐electron O2 reduction. Therefore, the enhanced photocatalytic H2O2 generation performance of the developed CPKCN is achieved, with an H2O2 generation rate of 3.7 mmol g−1 h−1 under visible light in a 10 vol% isopropanol (IPA) aqueous solution, and with the apparent quantum yield of 16.7% at 420 nm and the solar‐to‐chemical conversion efficiency of 0.34%. The work offers new insights into developing efficient photocatalysts for various applications.
Soil and weed management effects on floral hemp (Cannabis sativa L.) production and cannabinoid content
Authors: Jemison John M. 
Published: June 2024

AbstractMany floral hemp (Cannabis sativa L.) growers rely on tillage and black plastic mulch to prepare soil for transplants, warm the soil, and control weeds. However, plastic waste and its high cost to growers drive the need for research to assess alternative weed and soil management practices. Experiments were conducted at two Maine locations in 2021 and 2022 to compare cover crop soil and weed management systems on hemp production, cannabinoid concentrations, and yield. Experimental treatments included (1) tilled raised bed‐black plastic mulch, (2) biweekly cultivation, (3) no weed control, and (4) mowed no‐till mowed winter rye (Secale cereale L. Aroostook). Experimental sites received twice the 30‐year monthly average rainfall in July and September 2021 leading to poorer production versus typical 2022 long‐term average rainfall. Ice damage reduced winter rye biomass in 2022 at University of Maine Rogers Farm, leading to several significant year by location and year by weed management interactions. Hemp grown in the no‐till winter rye mulch developed more slowly, produced lower yields, and had higher weed densities than cultivated or black plastic mulch treatments. Plant size, yield, and cannabinoid content were generally equivalent where weeds were controlled. Raised bed‐black plastic soil and weed management were most effective under excessively wet conditions to reduce soil moisture and improve drainage. Cannabinoid concentrations did not increase under high weed pressure, but cannabinoid yield was influenced by flower production, which was significantly lower in the mowed rye mulch and control treatments. Blending raised bed production with efficient cultivation warrants research attention.
