“…Although the functional consequences are still unknown, a few studies have reported that the sperm alignment is able to change in SMFs. The sperm head consists of a nucleus, and the tail mainly consists of long bundled microtubules that have diamagnetic anisotropy, which make it sensitive to the magnetic field [Vassilev et al, 1982; Torbet and Dickens, 1984; Zhang and Zhang, 2019]. For example, Takeuchi et al [2003] and Emura et al [2003] found that the orientation of the whole bull sperm and sperm head alone were both perpendicular to the magnetic field direction at 1.5 and 1.7 T SMFs generated by electromagnets.…”

“…There are multiple mechanisms for SMF‐induced bioeffects on reproduction, especially high‐intensity SMFs. First of all, it has been shown that SMFs can affect cytoskeleton structures, including microfilament, microtubule, and spindle, which consequently affect cell division [Zhang et al, 2017b; Zhang and Zhang, 2019], which provide a fundamental explanation for high SMF‐induced reproduction abnormities. For example, Denegre et al [1998] analyzed the length of the astral microtubules, the diamagnetic anisotropy, and the bending stiffness of the microtubules and concluded that the effects of SMF on the cleavage plane should be caused by the SMF action on microtubules.…”

With the wide application of magnetic resonance imaging in hospitals and permanent magnets in household items, people have increased exposure to various types of static magnetic fields (SMFs) with moderate and high intensities, which has caused a considerable amount of public concern. Studies have shown that some aspects of gametogenesis and early embryonic development can be significantly affected by SMFs, while others have shown no effects. This review summarizes the experimental results of moderate to high‐intensity SMFs (1 mT–16.7 T) on the reproductive development of different model animals, and we find that the effects of SMFs are variable depending on experimental conditions. In general, the effects of inhomogeneous SMFs seem to be more significant compared to that of homogeneous SMFs, which is likely due to magnetic forces generated by the magnetic field gradient. Moreover, some electromagnetic fields may have induced bioeffects because of nonnegligible gradient and heat effect, which are much reduced in superconducting magnets. We hope this review can provide a starting point for more in‐depth analysis of various SMFs on reproduction, which is indispensable for evaluating the safety and potential applications of SMFs on living organisms in the future. © 2022 Bioelectromagnetics Society.

“…For the binder applied to Li–S batteries, it is not enough to satisfy the bonding function in the cathode. Current research is considering the polymer structure to impart the binder with some special functions, such as inhibiting the shuttle effect by adsorption or transformation, self-repairing ability to cope with volume expansion, and improving the electrochemical reaction of the cathode by utilizing the good ionic and electronic conductivity. − Among a variety of polymer binders, ionic polymers, which utilize polar polymer chains and electrostatic interactions with ions, are considered a promising material for achieving good bonding performance . Anionic polymers (e.g., lithiated PAA binder, lithiated Nafion binder, and CMC binder) have negatively charged polymer chains that facilitate faster lithium-ion conduction in the cathode, thereby enhancing the electrochemical reaction process.…”

Lithium−sulfur (Li−S) batteries, possessing substantial capacity, present a promising successor to current lithium-ion batteries, but the "shuttle effect" during cycling and deficient lithium-ion conductivity in Li−S batteries limit their practical applications. One potential remedy to these issues lies in the use of functional binders. In this study, building on the exceptional electrochemical stability of poly(vinylidene fluoride) (PVDF), we strategically grafted the cationic monomer 1-butyl-3-vinylimidazole with bis(trifluoromethanesulfonyl)imide (TFSI − ) coordination from the chain of PVDF, thereby engineering the ionomer binder PVDF-g-(1-butyl-3-vinylimidazolium bis((trifluorompropyl)sulfonyl)imide) (BVIM). Density-functional theory (DFT) calculations affirmed that these cationic polymer branches, possessing a high binding energy with lithium polysulfides (LiPSs), are effective in trapping the LiPSs generated at the cathode. Moreover, while adsorbing LiPSs the TFSI − originally coordinated with the branched chain will be displaced, forming a dynamic small molecule pathway in the cathode that promotes lithium-ion conduction. As a result, Li−S batteries with BVIM binders deliver a persistent reversible capacity of 792.5 mAh g −1 over 250 cycles at a rate of 0.5C. Concurrently, at a high sulfur loading of 5.5 mg cm −2 , a specific capacity of 3.3 mAh cm −2 was maintained after 50 cycles at 0.2C.

“…To verify the effect of MF on the freezing progress and quality of white shrimp, we designed a magnetic field assisted immersion freezer that can generate a uniform magnetic field, the actual magnetic field strength for food freezing can be measured in real time, and the thermal effects of magnetic field generation can be eliminated. Magnetic fields are classified according to their intensity as weak (<1 mT), medium intensity (1 mT ∼ 1 T), strong (1 T ∼ 20 T) and ultra-strong (>20 T) ( Zhang, Li, & Zhang, 2019 ). Abie et al (2021) utilized a lower magnetic field of 2 mT to freeze meat samples with unsatisfactory results, while Otero and Pozo (2022) used a greater static magnetic field of 150-200 mT, 107 to 359 mT to freeze potatoes and saline with disappointing performances, too ( Abie et al, 2021 , Otero and Pozo, 2022 ).…”
