The increasing demand for sustainable and eco-friendly materials has sparked interest in biobased polymers, especially in the field of epoxy resins. This review examines recent progress in producing biobased epoxy polymers as substitutes for environmentally harmful petroleum-derived resins, especially the widely utilized diglycidyl ether of bisphenol A (DGEBA). Several renewable alternatives with comparable or improved performance traits have been developed. The review focuses on five prominent biobased sources for epoxy synthesis: polyphenol, lignin, vanillin, sorbitol, and vegetable oil. This review delves into the chemical modifications and polymerization techniques applied to these biobased precursors to achieve desirable epoxy properties, such as mechanical strength, thermal stability, and curing behavior. Furthermore, the paper discusses the challenges and limitations faced during the synthesis of biobased epoxy polymers, including the issues of cost, scalability, and industrial applicability. By exploring various biobased sources and their utilization in epoxy synthesis, this review aims to inspire further research and innovation in the quest for environmentally responsible materials in epoxy applications. © 2023 IEEE.

Motion monitoring using electronic fibers plays a pivotal role in personal healthcare, disease detection, and diagnosis. While existing studies primarily focus on enhancing the accuracy and sensitivity of electrical sensing signals, these signals remain invisible to the naked eye, hindering intuitive user experiences. Here, we propose a novel luminous fiber based on the mechanoluminescence (ML) effect. This fiber enables real-time visual sensing of external mechanical forces without relying on additional electronic components such as batteries or chips. This ML fiber features a simple structure and good stability, which consists of a core layer of ZnS:Cu2+ composite elastic material and a sheath layer of silicone rubber elastomer. Notably, within a tensile strain range of 30%, the ML fiber emits visible green light at 520 nm, with light intensity positively correlated to tensile acceleration. Our design strategy presents a viable solution for future motion management applications. © 2024 Fraunhofer IZM.

Electrochemical impedance spectroscopy (EIS) is widely used in electrochemistry, energy sciences, biology, and beyond. Analyzing EIS data is crucial, but it often poses challenges because of the numerous possible equivalent circuit models, the need for accurate analytical models, the difficulties of nonlinear regression, and the necessity of managing large datasets within a unified framework. To overcome these challenges, non-parametric models, such as the distribution of relaxation times (DRT, also known as the distribution function of relaxation times, DFRT), have emerged as promising tools for EIS analysis. For example, the DRT can be used to generate equivalent circuit models, initialize regression parameters, provide a time-domain representation of EIS spectra, and identify electrochemical processes. However, mastering the DRT method poses challenges as it requires mathematical and programming proficiency, which may extend beyond experimentalists’ usual expertise. Post-inversion analysis of DRT data can be difficult, especially in accurately identifying electrochemical processes, leading to results that may not always meet expectations. This article examines non-parametric EIS analysis methods, outlining their strengths and limitations from theoretical, computational, and end-user perspectives, and provides guidelines for their future development. Moreover, insights from survey data emphasize the need to develop a large impedance database, akin to an impedance genome. In turn, software development should target one-click, fully automated DRT analysis for multidimensional EIS spectra interpretation, software validation, and reliability. Particularly, creating a collaborative ecosystem hinged on free software could promote innovation and catalyze the adoption of the DRT method throughout all fields that use impedance data. © 2024 Elsevier Inc.

Stairmand-type cyclones are commonly used in industry to separate particles from gas streams by inertia, driven by the dual-vortex flow patterns. Here, new designs are proposed to eliminate the local non-ideal vortex patterns in a conventional Stairmand cyclone by inserting a flow divider at the entrance and adjusting the elbow exit orientation. A two-way coupled CFD–DPM approach is employed to analyze the performance of the modified cyclones. Simulation results show that the cyclone with the elbow exit oriented orthogonal to the entrance direction demonstrates better performance in terms of the cut size and sharpness. The installation of the flow divider reduces the vortex eccentricity by approximately 50%. The flow divider increases the gas velocity near the outer wall, allowing the quasi-free vortex in the cyclone's outer region to become nearly fully developed at the entrance section through the reduction of the local secondary recirculation flows. The optimum flow divider outer wall thickness correlates to the wall shear stress distribution. With the optimum 2 mm outer wall thickness flow divider installed, the separation efficiency for 2 μm particles increases from 56.74% to 77.4%, and the cut size decreases from 1.87 μm to 1.23 μm. © 2025 The Society of Powder Technology Japan

Bulk polymerization is one of the most commonly used techniques in polymer preparing due to its relatively simple process,low cost and easier aftertreatment of the product[1-5].Bulk polymerization has attracted much attention in both academic researches and industrial productions of commodity polymers,such as poly(methyl methacrylate)(PMMA)[6]and polystyrene(PS)[7].During the process of bulk polymerization,an autoacceleration phenomenon,which is also referred to as the gel or Trommsdorff effect,is often observed[8].

Styrene-Maleic Anhydride Copolymers for High-Performance Triarylamine-Containing Electrochromic Materials

ACS Applied polymer Materials 2024年第6期6卷 3554-3563页

A facile approach was employed to produce thermosets of styrene-maleic anhydride copolymers (SMA) containing three kinds of triarylamine moieties to elucidate electrochromic (EC) behaviors comprehensively, and an additional ionization modification was also applied to explore the effect on counterion diffusion kinetics during the electrochemical process. The commercially available SMA was chosen as the starting material for coupling with three triarylamine-based diamine monomers, 4,4′-diamino-4″-methoxytriphenylamine (3Ph), N,N′-bis(4-aminophenyl)-N,N′-di(4-methoxylphenyl)-1,4-phenylenediamine (5Ph), and 4,4′-bis[4-aminophenyl(4-methoxyphenyl)amino)]-4″-methoxytriphenylamine (7Ph), resulting in colorless and transparent thermoset polymer films with different interchain distances. Furthermore, the precursors of these polyamic acids could be reacted with triethylamine (Et3N) to form the related triethylammonium-containing PAA complexes, which could facilitate the migration of counterion during redox procedures. After evaluating the electrochemical and EC behaviors, we demonstrate that the merge of enlarging interchain distance and ionization modifications in the triarylamine-coupling SMA copolymer matrixes leads to synergistic effects in the diffusion dynamics of the electrolyte counterion and could effectively enhance higher diffusion rates (D) of the counterion in the polymer matrix with more than 2,400 times larger (iS5Ph: 96.73 cm2 s-110-18) than the triphenylamine-based linear type polyimide, L3Ph (0.04 cm2 s-110-18), and the prepared electrochromic device (ECD) properties revealed faster coloration response speed (υc) 43.7% s-1 and outstanding coloration efficiency (ηCE) up to 540 cm2/C. © 2024 The Authors.

The construction and application of metal-organic cages with accessible internal cavities have witnessed rapid development, however, the precise synthesis of complex metal-organic capsules with multiple cavities and achievement of multi-guest encapsulation, and further in-depth comprehension of host-multi-guest recognition remain a great challenge. Just like building LEGO blocks, herein, we have constructed a series of high-order layered metal-organic architectures of generation n (n = 1/2/3/4 is also the number of cavities) by multi-component coordination-driven self-assembly using porphyrin-containing tetrapodal ligands (like plates), multiple parallel-podal ligands (like clamps) and metal ions (like nodes). Importantly, these high-order assembled structures possessed different numbers of rigid and separate cavities formed by overlapped porphyrin planes with specific gaps. The host-guest experiments and convincing characterization proved that these capsules G2-G4 could serve as host structures to achieve multi-guest recognition and unprecedentedly encapsulate up to four C60 molecules. More interestingly, these capsules revealed negative cooperation behavior in the process of multi-guest recognition, which provides a new platform to further study complicated host-multi-guest interaction in the field of supramolecular chemistry. © 2024 The Royal Society of Chemistry.
