Imparting functionality into porphyrin metal–organic framework aerogels with uniform distributions for diversified applications

The incorporation of various functional nanoentities into pure metal–organic framework (MOF) aerogels can not only introduce additional functionality but also expands the application scenarios of MOF aerogels. Herein, a general and simple strategy for uniform incorporation of various functional nanomaterials into a porphyrin MOF aerogel is presented. Specifically, this strategy primarily involves the introduction of a surfactant polyvinylpyrrolidone (PVP) to disperse the nanomaterials in lipophilic solvents, followed by a direct solvothermal reaction with the precursors of the porphyrin MOF aerogel. Additionally, uniform aerogel composites consisting of two MOF components have also been developed by careful optimizing the reaction conditions. The resulting nanoentity@MOF aerogel composites exhibit positive properties that stem from the synergistic effects between the nanoentities and MOF aerogel, offering advanced applications in areas such as photochemical electrochemistry, adsorption and photodegradation, electrochemical oxygen reduction reaction, and fluorescence.

The Veterinary Student Survey on Patient Safety Culture (VSSPSC): A Quantitative and Qualitative Exploration of American Veterinary Students' Perceptions of Patient Safety Culture.

Patient safety culture (PSC) is a multidimensional construct that reflects the way healthcare organizations promote safe patient care. Veterinary students are explicitly and implicitly indoctrinated into organizational cultures and will carry these attitudes and behaviors into their future work. In this study, we evaluated the psychometric properties of a PSC survey among veterinary students in the United States and investigated their attitudes toward PSC. Exploratory factor analysis identified factors that explained portions of the variance in responses. Importantly, the measures derived from those factors predicted the likelihood of a student mentioning a negative experience/opinion regarding error reporting. Most students reported receiving explicit training in communication, but coursework in other areas, such as human factors and safety culture, was uncommon. Veterinary students generally reported high levels of agreement with the tenets of patient safety science, though some items demonstrated wide variation in responses, underscoring the need for more uniform incorporation of education in veterinary PSC.

Hybrid proteins containing proteorhodopsin from <i>Exiguobacterium sibiricum</i>

The genes of hybrid proteins including Exiguobacterium sibiricum proteorhodopsin (ESR) and various N-terminal soluble domains have been constructed. Effective synthesis in Escherichia coli cells was observed only in the case of hybrids with chaperone Caf1M and maltose-binding protein MBP expressed as precursors with their own signal sequences. The study of the isolated MBP-ESR protein in micelles and proteoliposomes demonstrated formation and decay of the main photocycle intermediates at pH 8. The photoelectric response of the hybrid proteins Caf-ESR and MBP-ESR is comparable in amplitude to the wild-type ESR response, indicating their homogeneous orientation in the membrane. The obtained constructions can be used to create bacterial expression systems for various retinal proteins, ensuring their uniform incorporation into proteoliposomes.

Gamma‐ray‐induced modification of poly(ethylene terephthalate) and polypropylene solid materials with halogen‐containing olefins for X‐ray CT image contrast enhancement

AbstractIt is known that X‐ray CT of organic polymer materials usually provides low‐contrast images because of the low X‐ray absorption of these materials. In this paper, we describe a new method to enhance the contrast of X‐ray CT images of organic polymer materials. We demonstrate that gamma‐ray irradiation of poly (ethylene terephthalate) (PET) fibers in dichloromethane containing 2‐bromoethyl methacrylate, 2‐chloroethyl methacrylate, or 4‐bromostyrene results in the grafting of halogen‐containing oligomeric chains onto the PET fibers. Focused ion beam scanning electron microscopy (FIB‐SEM) and time‐of‐flight secondary ion mass spectrometry (TOF‐SIMS) analyses revealed a homogeneous distribution of bromine atoms within the 2‐bromoethyl methacrylate‐modified PET fibers, not only on the surface. This uniform incorporation translated to a significant improvement in X‐ray CT image contrast compared with pristine fibers. Similar treatment of polypropylene pellets also enhanced the contrast of their X‐ray CT images. This is a new simple and effective method to enhance the X‐ray CT image contrast and potentially applicable to various polymer materials including polymer composites and porous polymer materials, readily allowing the observation of their 3D microstructures finely.

Direct synthesis of undoped/doped SrTiO3 nanoparticles from solution

Directly crystallizing strontium titanate (SrTiO3) nanoparticles from a solution near room temperature poses a challenge due to Ti ions easily form colloids and result in amorphous products. It is also difficult to ensure the uniform incorporation of the dopants into the lattice during synthesis of doped samples. This study successfully achieved this task using the direct synthesis from solution (DSS) method. Both undoped SrTiO3 nanoparticles and Fe-doped one were synthesized in an ethanol solution at the temperatures ranging from 60 to 80 °C, resulting in homogeneous grains with an average size of approximately 15 nm. Despite the solubility limit of Fe3+ in bulk SrTiO3 being around 2.5 %, we successfully synthesized Fe-doped SrTiO3 nanocrystals with high doping level even at a dose of 10 %.The tribocatalytic performance of both undoped and Fe-doped SrTiO3 nanoparticles was evaluated for methylene blue degradation in a solution. Undoped SrTiO3 nanoparticles showed similar catalytic performance to P25. In contrast, Fe-doped SrTiO3 nanoparticles exhibited much higher catalytic performance. This enhanced catalytic performance is attributed to the presence of oxygen vacancies, which are introduced by doping Fe3+ into the SrTiO3 lattice to substitute the Ti ion.

Diversifying Ion-Transport Pathways of Composite Solid Electrolytes for High-Performance Solid-State Lithium-Metal Batteries.

The application of composite solid electrolytes (CSEs) in solid-state lithium-metal batteries is limited by the unsatisfactory ionic conductivity underpinned by the low concentration of free lithium ions. Herein, we propose an interface design strategy where an amine silane linker is employed as a coupling agent to graft the Li7La3Zr2O12 (LLZO) ceramic nanofibers to the poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) polymer matrix to enhance their interaction. The hydrogen bonding between amino-functionalized LLZO (NH2@LLZO) and PVDF-HFP not only effectively induces a uniform incorporation of high-content nanofibers (50 wt %) into the polymer matrix but also furnishes sufficient continuous surfaces to weaken the complexation between PVDF-HFP and Li-ion carriers. Additionally, introduction of the hydrogen bond and Lewis acid-base interplay strengthens the interfacial interactions between NH2@LLZO and lithium salts that release more free lithium ions for efficient interfacial transport. The impact of the linker's structure on the dissociation capacity of lithium salts is systematically studied from the steric effect perspective, which affords insights into interface design. Conclusively, the composite solid electrolyte achieves a high ionic conductivity (5.8 × 10-4 S cm-1) by synergy of multiple transport channels at ceramic, polymer, and their interface, which effectively regulates the lithium deposition behavior in symmetric cells. The excellent compatibility of the electrolyte with both LiFePO4 and LiNi0.8Co0.1Mn0.1O2 cathodes also results in a long lifetime and a high rate capability for full cells.

Effect of Keratin Waste on Poly(ε-Caprolactone) Films: Structural Characterization, Thermal Properties, and Keratinocytes Viability and Proliferation Studies

Keratin extracted (KE) from chicken feathers was used for the production of composite films comprising poly(ε-caprolactone) (PCL) and keratin (PCL/KE films). The process involved the extraction of keratin from chicken feathers using a 0.1 M NaOH solution, followed by characterization via sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The PCL was synthesized through the ring-opening polymerization (ROP) of ε-caprolactone (ԑ-CL) with Sn(Oct)2 as a catalyst. Films were prepared via solvent casting, including pure PCL films and those enriched with different weight percentages of KE (10%, 15%, 25%, and 30%). The films were characterized by differential scanning calorimetry (DSC), thermogravimetric analysis (TG), and scanning electron microscopy (SEM). SEM analysis revealed a more uniform incorporation of KE within the PCL matrix in the case of the 15% keratin-enriched film (PCL/KE15) as compared to other keratin percentages. The thermal analysis showed a positive influence of keratin on the thermal stability of the films. Keratinocytes viability and proliferation tests on the PCL/KE15 film demonstrated compatibility with cells. Collectively, these results hold relevance for potential biomedical applications of PCL/KE films.

This study presents a comprehensive investigation into the synthesis, structural-spectroscopic characterization, and optical properties analysis of Sm3-activated NaZnPO4 phosphors with varied Sm3+-doping percentiles, aimed at developing tunable luminescent materials for white-light-emitting diode (WLED) applications. The polycrystalline samples NaZn(1-x) Smx3+ PO4 (x = 0.00, 0.05, 0.10 and 0.15) phosphors were synthesized via a solid-state reaction method. X-ray diffraction data analysis confirms single phase monoclinic lattice with space group P 1 21/c 1 for all compositions. The Rietveld procedure also confirms the single phase and monoclinic structure of synthesized phosphors. Fourier-transform infrared) spectroscopy confirms compositional homogeneity. FE-SEM micrographs show irregularly stacked microstructures and morphology for all compositions irrespective of Sm3+ doping percentage. While EDS and Elemental mapping confirm uniform incorporation of Sm3+ ions in phosphors lattice. Diffuse Reflectance Spectra studies show Sm3+ doping resulted in redshift and band gap narrowing. In Photoluminescence spectroscopies, excitation and emission spectra reveal that distinctive photoluminescence spectra with notable emission peaks at 402 nm (6H5/2 → 4F5/2) and 599 nm (4G5/2 → 6H5/2). CIE chromaticity coordinates demonstrated varied color purity and coordinates for different doping levels, with promising orange-red emissions and increased luminosity. The observed optical properties suggest the potential suitability of Sm3+-activated NaZnPO4 phosphors as promising candidates for enhancing WLED efficiency and color quality.

Experimental investigation into the self-carbonation mechanism of magnesium oxide carbon sequestration foamed concrete

A novel technique involves the preparation of foamed concrete utilizing MgO as a substitute for Portland cement (PC) and CO2 foam in place of air foam. This technique is referred to as “magnesium oxide (MgO) carbon sequestration foamed concrete (MCFC)" that enables self-carbonation of Reactive MgO cement-based concrete under ambient conditions without any accelerated carbonation curing conditions. The developed technology enhances the carbonation efficiency of MgO-based materials by combining a foaming agent with CO2 curing. The even mixing of CO2 foam with MgO, referred to the uniform distribution and incorporation of CO2 throughout the sample, facilitated by the foaming agent, leads to the production of ions within the cement, promoting the carbonation of dissolved Mg2+ ions and the formation of hydrated magnesium hydroxyl carbonates (HMHCs). Eight sample groups were prepared to explore the potential of MCFC in CO2 sequestration. XRD, TG-DTA, and SEM techniques were employed to investigate the mineral phase and carbonation products in MCFC. The pore structure, pore-size distribution, and porosity of MCFC under different curing conditions were investigated using X-ray and NMR. The self-carbonation enabled by CO2 foams improved the microstructure and mechanical performance of MgO-based samples. Notably, the morphology, microstructure, and carbonate content improvements resulted in a significant 100% increase in the 28-day compressive strengths (2 MPa) compared to the control sample cured under ambient conditions.

Research primarily concentrates on incorporating nanomaterials, like titanium dioxide and silver, into textile substrates for enhanced functionalities such as self-cleaning, UV protection, and antimicrobial properties. Metal oxide nanoparticles, particularly Ag and TiO2, exhibit remarkable efficacy in combating microorganisms. Sol-gel techniques play a crucial role in surface modification, facilitating better adhesion of nanomaterials and enabling diverse applications in materials science. This study focuses on utilizing silver and titanium nanoparticles for antimicrobial and dirt-repellent properties in lightweight fabrics, showcasing a preliminary step towards uniform incorporation for subsequent evaluation.

Lewis Acidic Aluminosilicates: Synthesis, 27Al MQ/MAS NMR, and DFT-Calculated 27Al NMR Parameters.

Porous aluminosilicates are functional materials of paramount importance as Lewis acid catalysts in the synthetic industry, yet the participating aluminum species remain poorly studied. Herein, a series of model aluminosilicate networks containing [L-AlO3] (L = THF, Et3N, pyridine, triethylphosphine oxide (TEPO)) and [AlO4]- centers were prepared through nonhydrolytic sol-gel condensation reactions of the spherosilicate building block (Me3Sn)8Si8O20 with L-AlX3 (X = Cl, Me, Et) and [Me4N] [AlCl4] compounds in THF or toluene. The substoichiometric dosage of the Al precursors ensured complete condensation and uniform incorporation, with the bulky spherosilicate forcing a separation between neighboring aluminum centers. The materials were characterized by 1H, 13C, 27Al, 29Si, and 31P MAS NMR and FTIR spectroscopies, ICP-OES, gravimetry, and N2 adsorption porosimetry. The resulting aluminum centers were resolved by 27Al TQ/MAS NMR techniques and assigned based on their spectroscopic parameters obtained by peak fitting (δiso, CQ, η) and their correspondence to the values calculated on model structures by DFT methods. A clear correlation between the decrease in the symmetry of the Al centers and the increase of the observed CQ was established with values spanning from 4.4 MHz for distorted [AlO4]- to 15.1 MHz for [THF-AlO3]. Products containing exclusively [TEPO-AlO3] or [AlO4]- centers could be obtained (single-site materials). For L = THF, Et3N, and pyridine, the [AlO4]- centers were formed together with the expected [L-AlO3] species, and a viable mechanism for the unexpected emergence of [AlO4]- was proposed.

4D printed zero Poisson’s ratio metamaterials with vibration isolation properties for magnetic response

Although mechanical metamaterials possess high specific energy absorption, they suffer from drawbacks such as irreversible deformations and non-adjustable mechanical properties. Magnetic excitation is considered to be one of the most promising methods for special working environments; for which uniform incorporation of UV-cured four-dimensional (4D) printed resin is considered to be an effective approach to achieving fine structural features. Our study investigated the impact of soft magnetic particle content on the mechanical and dynamic mechanical properties of a shape memory polymer matrix material. This paper presents a 4D printed metamaterial with a zero Poisson’s ratio that can sense magnetic field intensity and alter its mechanical properties. Its rapid shape recovery, achieved through magnetic excitation, enables multiple energy absorption within a short timeframe. By increasing the curvature radius, the stress concentration in the hexagonal honeycomb structure is reduced, ensuring the metamaterial maintains its zero Poisson’s ratio even under in-plane loading. The study investigates the energy absorption performance and force–displacement curve of metamaterials with different layers and cell sizes, focusing on a four-layer metamaterial for the analysis. Furthermore, the paper explores the tunable energy absorption characteristics of the four-layer metamaterial under time-varying electromagnetic fields, aiming to enhance the stability of a lander’s center of gravity while landing on uneven terrain.

Optimizing post-synthetic metal incorporation in mixed-linker MOFs: insights from metalation studies on bipyridine-containing UiO-67 single crystals.

The postsynthetic metalation (PSM) of metal-organic frameworks (MOFs) with intrinsic metal binding sites is an intriguing strategy to introduce catalytic function into MOFs. The spatial distribution of the catalytic sites within the MOF crystal will affect the efficiency of the material, but the factors that govern depth distribution of the introduced metal sites are often not well understood. Herein, we employ Rutherford backscattering spectrometry (RBS) to investigate the metal distribution in a series of post-synthetically metalated mixed linker bpdc/BPY UiO-67 (UiO = Universitet i Oslo, bpdc = biphenyl-dicarboxylate, BPY = 2,2'-bipyridine-5,5'-dicarboxylate) single crystals as a function of linker ratio and metalation time. The RBS spectra reveal large differences in the depth distribution of inserted Ni2+ ions, and core/shell architectures are observed in high BPY materials at shorter incubation times. The incubation times to achieve uniform metal incorporation increases with increasing BPY ratios in the materials, suggesting that the presence of the BPY linkers slow down metal uptake. We propose a combination of ionic interactions and pore clogging, where coordinated ions reduce the available pore space for further ions to diffuse deeper into the framework as reasons for the observed trends. The observations are likely relevant for other mixed-linker MOF systems, and understanding the effect that linker ratios have on PSM and cation distribution will aid in future optimizations of catalytic MOFs.

Interpenetrating gel-enabled uniform integration of metal and carbon dual matrices with nanoporous silicon for high-performance lithium storage

Study the Wear Characteristics for Ni‐ZrO2 and Ni‐Al2O3 Nanocomposite Coatings Produced by Electroless Deposition Technique

Metal matrix nanocomposite coatings are promising for tribological applications given their superior hardness and wear resistance compared to metals. The point of this study was to describe the shape and long‐term performance of nickel‐based coatings that were put on stainless steel using electroless codeposition and made stronger with nanoparticles of zirconia (ZrO2) and alumina (Al2O3). Scanning electron microscopy showed the uniform incorporation of nanoceramics within nickel matrices. Pin‐on‐disk tribotests evaluated wear performance across loads from 5 to 15 N and sliding speeds up to 480 cm/min. Increasing nanoparticle content from 2 to 4 g/L markedly reduced wear rate due to enhanced hardness and density. At all tested loads, Ni‐ZrO2 and Ni‐Al2O3 nanocomposites exhibited considerably lower wear than monolithic nickel. The nanometal matrix particles hindered plastic deformation, with weight losses up to 68% lower than base nickel. Initially, wear resistance rose proportionally with sliding speed resulting from protective oxide layers until abrasive wear prevailed. The nanoparticle reinforcement dramatically extended durability, making it ideal for tribological systems involving mixed or abrasive conditions. More research needs to be done to find the best compositions and other matrix materials to use for these nanoscale strengthening effects.

Biomimetic Photothermal Actuator Exhibits Robust Motion and Omnidirectional Phototropism

Organisms in the natural world receive signals from the external environment and exhibit continuous propulsion. However, creating artificial systems that can rapidly track energy sources in real-time without human intervention and electronic circuit programming poses a significant challenge. Here, we have developed a soft actuator that mimics the phototropism of plants and possesses autonomous sensing and driving capabilities. The soft actuator is based on a thermo responsive PNIPAAM hydrogel, and its uniform incorporation of light-absorbing agents imparts photothermal response characteristics. Our preparation method involves a combination of ice templating and UV cryo-polymerization techniques, utilizing water as the primary solvent. This process results in the formation of substantial microscopic pores within the PNIPAAM hydrogel, greatly enhancing the rate at which water enters and exits the polymer network. The rapid response and recovery properties of the hydrogel soft actuator allow it to quickly track and align with a stimulus light source. Moreover, it can bend to 90° and undergo continuous oscillations, representing a substantial enhancement in performance compared to conventional composite PNIPAAM hydrogels. Furthermore, the soft actuator exhibits a low dependence on the type of incident light, as it can respond not only to pinpoint laser beams but also to broad-spectrum white light. This intelligent soft actuator holds promising applications in non-contact soft robotics, underwater propulsion systems, and various other fields.

Uniform incorporation of two-dimensional BiOBr into perovskite crystals and films to enhance photoluminescence

The all-inorganic perovskite nanocrystals are promising luminescent materials for optoelectronic devices. However, it is still a challenge to prepare perovskite nanocrystals with high luminescence. Herein, a synthesis method was developed for the uniform incorporation of ultra-thin BiOBr nanosheets into perovskite crystals at both body-embedding and surface-passivating positions. The micron-scale green-emitting phosphors composed of Cs4PbBr6 nanocrystals and BiOBr nanosheets are prepared. The crystal structure of Cs4PbBr6 nanocrystals can remain almost unchanged although prepared from different PbBr2 concentrations. The luminescence mechanism of Cs4PbBr6 is discussed. The Cs4PbBr6@BiOBr submicron phosphors can be dispersed in DMSO solvent without disintegration and dissolution, which are used as seeds of the CsPbBr3 film growth. The CsPbBr3 films with Cs4PbBr6@BiOBr doped exhibit pure optical characteristics of CsPbBr3, indicating that Cs4PbBr6 is converted to CsPbBr3 during the film preparation process. Furthermore, these Cs4PbBr6@BiOBr phosphors are mixed with CaAlSiN3: Eu red-emitting commercial phosphors to make white LEDs (WLEDs). Overall, this study provides a revealing insight into a kind of composite material constructed with halide perovskite and bismuth halide oxide.

Fabrication of MgO nanorods blended cellulose acetate-based mixed matrix membranes for selective gas separation of H2/CH4, CO2/CH4 and H2/CO2: Effect of loading and pressure

The growing interest in polymer-based mixed matrix membranes (MMMs) in the field of gas separation encouraged the authors to fabricate MgO nanorods and cellulose acetate (MgO-X/CA) MMMs for the separation of H2/CH4, CO2/CH4, and H2/CO2 gases. The facile solution-casting, followed by solvent evaporation technique, was applied to fabricate MMMs. FE-SEM, EDS, FT-IR, XRD, DSC, and TGA characterization techniques were used to investigate the physico-chemical properties of fabricated MMMs, whereas the gas transport properties of MMMs were investigated using a gas permeation setup. Upon uniform MgO nanorods incorporation in CA polymer, the gas permeation through MMMs is improved due to disruption of the polymer chain. The influence of feed pressure and various loadings of nanorods (5, 10, and 15 wt%) on gas permeability and selectivity of CA based MMMs were investigated at 25 °C and 1–4 bar gas pressure. Based on the results, the MgO-15/CA MMMs achieved the highest H2 permeability of 77.80 Barrer which is higher than pure CA by 45%, with a two-fold increase in H2/CO2 selectivity and unchanged H2/CH4 selectivity. Meanwhile, MgO-5/CA MMMs revealed the highest CO2 permeability of 62.90 Barrer with an increased in CO2/CH4 selectivity from 22.30 to 24.30.

Effect of Platinum Oxide in Enhancing EMI Shielding Effectiveness of Silver Doped Polyaniline-Platinum Oxide Composites

In this study, we used green tea extract to prepare Silver-PANI nanocomposites and incorporated varying percentages of platinum oxide through in-situ chemical polymerization. The synthesized Ag-PANI/PtO2 conducting polymer nanocomposites were characterized using FT-IR, XRD, and SEM analysis, which showed uniform incorporation of PtO2 in the nanocomposites. EMI shielding effectiveness results demonstrated that the Ag-PANI/PtO2 (10%) composite effectively shields electromagnetic interference. The EMI SE results showed that PtO2 exhibited good absorption in the range of 2-3 GHz, indicating its conducting behaviour. Additionally, the Ag-PANI/PtO2 (6%) and Ag-PANI/PtO2 (10%) composites demonstrated good absorption in this range, likely due to the proper mixing of platinum oxide and silver-decorated polyaniline within the polymer matrix. Therefore, silver polyaniline decorated conducting polymer composites are a promising material for effectively shielding electromagnetic radiation in electronic devices.

In-situ growth of LiFePO4 with interconnected pores supported on carbon nanotubes via tavorite-olivine phase transition

Lithium iron phosphate (LiFePO4) has gained significant attention as a promising cathode material for lithium-ion batteries due to its excellent stability and safety characteristics. However, its relatively low electrical conductivity restricts its practical application in high-power devices. In this study, we propose a novel approach to improve the electrochemical performance of LiFePO4 cathodes by introducing carbon nanotubes (CNT) through an in-situ growth process. Firstly, CNT serve as nucleation sites for the growth of FePO4, which subsequently attaches and grows in situ on CNT, resulting in the precipitation of CNT/FePO4. Subsequently, pre-lithiation is performed to synthesize CNT/LiFePO4OH, which ensures efficient mass transfer and uniform reaction achieved by wet chemical lithiation process. Eventually,The improved lattice perfection of CNT/LiFePO4 is obtained through the tavorite-olivine phase transition at a low crystallization temperature, allowing for more favorable ion diffusion pathways. Furthermore, in conjunction with the uniform incorporation of CNT to enhance the overall conductivity of the composite, the presence of intrinsically interwoven pores entwined amidst a bedrock of LFP nanoparticles is unveiled. These intricately connected pores function as conduits, promoting the seamless diffusion of electrolyte across the composite structure. This, in turn, augments the interfacial engagement between the cathode and electrolyte, propelling a surge in electrochemical reactivity and harnessing a heightened level of electrochemical efficacy, thereby amplifying the overall electrochemical performance and efficiency. Electrochemical tests demonstrate that the CNT/LiFePO4 cathodes exhibit significantly prominent rate capability with 143.0 mAh g-1 at a rate of 20C, and remarkable cycling stability with a retention rate of ∼97.0% under 1000 cycles at 1C. The in-situ growth of CNT/LiFePO4 offers a simple and scalable approach for the modification of LiFePO4 cathodes, enabling the practical utilization of this promising material in high-performance lithium-ion batteries.
