Outer-Sphere Modulation of Zr-based Metal-Organic Frameworks for Nerve Agent Detoxification Organophosphorus nerve agents with extreme toxicity have been still used in the past few years. Recent advances in Zr-based metal-organic framework (MOF) catalysts have emerged as promising platforms for efficient nerve agent degradation, based on highly active Zr6 nodes and further enhancement of the activity via ligand functionalization. However, catalytic optimization confined to proximal modulation, where functional groups often interact with substrates, and thus impacts of outer-sphere modulation are still veiled. Here, we present a strong influence of outer-sphere modulation in optimizing the catalytic activity of Zr-based MOFs for nerve agent simulant degradation. A series of Zr-based MOFs with porphyrin ligands was prepared by substituting porphyrin cores with different metal ions (Al, Cu, Co, and Fe). Notably, the Fe-substituted MOF exhibited superior hydrolytic performance against a nerve agent simulant, achieving a half-life of just 5 minutes at 1 mol% catalyst loading. This performance is comparable to the most active Zr-based MOF catalysts reported to date. Our findings highlight a new perspective for optimizing catalytic metal nodes of Zr-based MOF via outer-sphere modulation and provide a new paradigm for engineering high-performance MOFs for chemical defense.

Synthesis and characterization of iron interlayers as modulators of optical and dielectric performance in ZnO thin films Abstract This work explores the influence of Fe interlayer thickness on the morphology, optical, and dielectric behavior of ZnO-based multilayer film prepared by a combined ALD-DC technique. Morphology was analyzed using focused ion beam (FIB) and energy-dispersive X-ray spectroscopy (EDX), while optical properties were evaluated through transmittance and reflectance measurements. The prepared lamellae confirmed well-defined thickness of each individual layer, and (EDX) confirmed the absence of other elements present in the thin-film samples under study. According to the results presented in the obtained figures, the increase of the Fe thickness in ZnO/Fe/ZnO system leads to a decrease in transmittance and an increase in reflectance, refractive index ( n ), extinction coefficient ( k ), and reflectivity ( R ref ). Both the real and imaginary parts of the dielectric constant (ε 1 &amp; ε 2 ) , as well as the dielectric loss (tanδ) increases with Fe content, while the optical quality factor (Q) decreases. Moreover, the carrier concentration to effective mass ratio (N/m * ) and both optical and electrical conductivity (σ opt &amp; σ elec ) increases, whereas the electrical modulus (M * ) decreases with increasing Fe thickness . The Wemple-DiDomenico single-oscillator (WDD) model was employed to determine the dispersion parameters, from which the nonlinear refractive index (n 2 ) and third-order nonlinear susceptibility (Χ (3) ) was estimated. These results highlight the significant role of Fe in tailoring the optical and dielectric properties of ZnO-based ͌͂ opto-electronics applications.

Poly (vinyl alcohol)/hydroxyapatite nanocomposite films with efficient adsorption and oil-water separation capabilities This study used two adsorptive hydroxyapatite nanorods (HAPR) and hydroxyapatite nanowires (HAPW) as modifiers. HAPR and HAPW with different aspect ratios have different abilities to induce axial alignment of adjacent Poly (vinyl alcohol) (PVA) molecular chains as nucleation sites. Thus, they can regulate the comprehensive properties of the two composite films. Tensile curves show that the properties of the two composite films are optimal when the PVA/HAPR ratio is 25% and the PVA/HAPW ratio is 10%. Compared with pure PVA films, they are improved by 2.17 times and 1.62 times, respectively. In addition, the optimized PVA/HAPW composite film has an adsorption capacity of 26.2 g/g for 1-Pentanol. This is due to the microporous structure and surface groups constructed by HAPW. This study provides a new research idea for the preparation of PVA/HAPR and PVA/HAPW composite films with simple processes. It has potential scalability in the direction of achievable industrial oil-water separation materials.

However, extreme weather and prolonged exposure to humidity can lead to the irreversible degradation of various materials used in built infrastructure, primarily due to water penetration and freeze-thaw cycles. This review examines the effectiveness and successful application of protective surface coatings on concrete, a major construction material. Superhydrophobic coatings meet the demands of various applications, offering anti-microbial resistance, corrosion resistance, contamination prevention, water repellence, drag reduction, anti-icing, anti-fogging, anti-adhesion features, and self-cleaning capabilities. Nanocomposites are known for their improved mechanical, thermomechanical, and thermal properties compared with their base materials, drawing considerable interest from researchers worldwide. The key problem of insufficient mechanical and chemical durability of superhydrophobic materials when applied on concrete surfaces is pointed out, and the application trend of these materials is projected. In addition, the tribology discussed in this review primarily addresses their mechanical durability, wear resistance, and long-term performance. This review also covers recent advancements in fabrication techniques, current limitations, and testing methods for superhydrophobic concrete. The effects of hydrophobic treatments on the hydration process, which is crucial for the development of compressive strength in concrete, are explored. Furthermore, successful case studies of superhydrophobic coatings for protecting concrete structures are presented. To develop maintenance strategies, prevent failures, and adhere to industrial standards, it is vital to assess the durability and characteristics of these coatings while considering factors such as mechanical stress, environmental exposure, and other qualitative aspects.

Ultrasound-enhanced water electrolysis for hydrogen production: Mechanisms, metrology and energy metrics Ultrasound intensifies hydrogen production in water electrolysis cells by thinning boun­dary layers, accelerating bubble detachment, and, in tuned windows, modulating cavi­tation chemistry, yet cross-study claims remain difficult to compare. Focusing on ultra­sound-enhanced water electrolysis (sono-electrolysis), this review aligns reporting with IEC 61161 (radiation-force acoustic power) and IEC 62127-2:2025 (hydrophone calibra­tion); requires delivered acoustic intensity at the electrode, Idel / W·cm⁻², with stated trace­ability; pairs isothermal control with uncertainty budgets; and benchmarks perfor­mance using Δ-metrics: Δj (current-density gain at fixed cell voltage), Δη (cell voltage/over­po­tential reduction at fixed current density) and ΔH₂ (hydrogen production rate gain at matched electrical input), together with specific energy consumption (SEC, kWh·kg⁻¹ H₂). A window-based synthesis indicates that, under isothermal operation, 20 to 40 kHz with delivered intensity ≈0.2 to 1.0 W·cm⁻² reproducibly yields Δj ≈ 15 to 30 %, Δη ≈ 40 to 120 mV, ΔH₂ ≈ 10 to 30 %, and net SEC improvements of ~8 to 12 % when auxiliary loads are included, whereas at higher dose (Idel ≈ 1.0 to 1.6 W·cm⁻²) non-uniform fields, cloud shielding, and heating can saturate or reverse benefits. To prevent metric conflation, hybrid sono-hydrogen routes are reviewed separately. The review concludes by proposing a minimum reporting set-frequency, waveform/duty and pulse repetition frequency, Idel (traceability/uncertainty), geometry/stand-off, electrolyte and dissolved gas, bulk tempe­rature and runtime, gas metrology with temperature/pressure cor­rections, SEC boun­daries and replicates/statistics, and by outlining priorities for operando cavitation-electro­chemistry co-registration, geometry/void-fraction-aware scale-up, and durability under combined fields, to support reproducible, energy-accounted, and comparable studies across laboratories.

Epoxy Network Hosts Confine Small Molecule Guests for Enhancing Phosphorescence Through F‐π and π‐π Synergistic Interactions ABSTRACT Organic room‐temperature phosphorescent (RTP) materials have attracted significant interest in information security and anti‐counterfeiting due to their unique afterglow properties. However, the role of non‐covalent interactions in enhancing phosphorescence remains insufficiently explored. Herein, we report a composite coating based on the synergistic effects of F‐π and π‐π stacking interactions within a dual‐phase 3D covalently cross‐linked network, by confining small molecular guests within an epoxy network host. The coating exhibits an ultra‐long room‐temperature phosphorescence (URTP) lifetime of up to 5.40 s, representing the longest lifetime reported in an epoxy resin system. The coating also displays switchable URTP and excellent surface characteristics, enabling the creation of rewritable anti‐counterfeiting labels through light‐activated printing and thermal erasure. Its low surface energy (15.85 mN·m −1 ) and self‐cleaning ability ensure the long‐term stability and concealment of encoded information. This work highlights the efficacy of engineering non‐covalent interactions for the development of high‐performance, erasable organic phosphorescent materials in anti‐counterfeiting applications.

Chiral Symmetry Breaking in Gelation Chiral symmetry breaking in gelation is a newly emerging research subject whose examples started to be reported after entering into this century. Although macroscopic chiral symmetry breaking that spontaneously affords an optically active gel from a racemic or achiral gelator solution has been regarded as a rare phenomenon, recent studies indicate that it might not be true and the phenomenon has just been overlooked. This review aims to promote the updates of researcher's understanding of chiral symmetry breaking in gelation, which can take place with a certain level of probability by optimizing the nucleation conditions for gelation.

SYNTHESIS OF CUO NANOPARTICLES BY CO-PRECIPITATION METHOD This abstract describes the successful synthesis of monoclinic copper oxide (CuO) nanoparticles using a simple and cost-effective co-precipitation method. The procedure involved dissolving a Copper (II) Chloride precursor, in deionized water and subsequently adding an alkaline solution, like sodium hydroxide (NaOH), dropwise under continuous magnetic stirring to achieve a specific pH (typically pH 8-12). The reaction leads to the formation of a black precipitate, which is then repeatedly washed with deionized water and ethanol to remove any residual impurities and by-products. The resulting precipitate is dried in a hot air oven and then calcined at an elevated temperature to obtain the crystalline CuO powder.

The cooperative influence of Ag(I) and sodium lauryl sulfate micelles on the oxidation rate of D-mannitol by acidic KMnO4 Oxidation of organic substrate by KMnO4 is fascinating because such process proceeds via different mechanistic pathway. No research has examined how metal catalysts affect carbohydrate oxidation by acidic KMNO4 in micellar environments. The impact of sodium lauryl sulfate (SLS) micelles on the Ag(I) facilitated oxidation kinetics of D-mannitol by KMnO4 has been investigated in the aqueous micellar media. The progression of the oxidation process is assessed by monitoring the decrease in absorbance, employing the pseudo-first-order condition as an indicator for [H+], [Mn(VII)], [Na2SO4], [D-mannitol], [Ag(I)], and [SLS]. The examined reaction shows fractional-first-order kinematics for [D-mannitol], [H+], and Ag(I), and first-order for [Mn(VII)] across the examined concentration range. The spectrophotometric kinetic investigation revealed that both Ag(I) and SLS catalyze the oxidation independently, yet their combined influence is significantly more pronounced. Ag(I) significantly increases the oxidation rate (5.5 times). Interestingly, the kinetic profile demonstrated an increase in the observed rate constant values (7.2 fold) corresponding to an increase in surfactant concentration. The combination of Ag(I) and SLS micelles produces an 11.5-fold enhancement in the oxidation rate of D-mannitol. The electrostatic attraction between the charged micelle and Mn(VII) promotes the proximity of the oxidizing species to the substrate (D-mannitol), which is typically solubilized in a micellar environment, thus enhancing the oxidation process. A credible mechanism that corresponds with the kinetic findings has been emphasized, alongside an analysis of the Piszkiewicz model, to elucidate the apparent catalytic influence of SLS micellar environments.
