Robust, ultra-flexible, and multifunctional MXene-basedelectromagnetic interference (EMI) shielding nanocomposite filmsexhibit enormous potential for applications in artificial intelligence,wireless telecommunication, and portable/wearable electronic *** this work, a nacre-inspired multifunctional heterocyclic aramid(HA)/MXene@polypyrrole (PPy) (HMP) nanocomposite paper withlarge-scale, high strength, super toughness, and excellent tolerance tocomplex conditions is fabricated through the strategy of HA/MXenehydrogel template-assisted in-situ assembly of PPy. Benefiting from the"brick-and-mortar" layered structure and the strong hydrogen-bondinginteractions among MXene, HA, and PPy, the paper exhibits remarkable mechanical performances, including high tensile strength (309.7 MPa),outstanding toughness (57.6 MJ m−3), exceptional foldability, and structural stability against ultrasonication. By using the template effect ofHA/MXene to guide the assembly of conductive polymers, the synthesized paper obtains excellent electronic conductivity. More importantly,the highly continuous conductive path enables the nanocomposite paper to achieve a splendid EMI shielding effectiveness (EMI SE) of 54.1 dBat an ultra-thin thickness (25.4 μm) and a high specific EMI SE of 17,204.7 dB cm2g−1. In addition, the papers also have excellent applicationsin electromagnetic protection, electro-/photothermal de-icing, thermal therapy, and fire safety. These findings broaden the ideas for developinghigh-performance and multifunctional MXene-based films with enormous application potential in EMI shielding and thermal management.

Objective To analyze the fertilization rate, embryo development and clinical outcome of oocytes with abnormal zona pellucida after in vitro fertilization （IVF） or intracytoplasmic sperm injection （1CS1）. Methods A retrospective analysis included a total of 43 cycles （27 IVF cycles and 16 ICSI cycles） in which oocytes displaying abnormal zona pellucida were retrieved between January 2006 and December 2011. The fertilization rate, embryo quality, and the cumulative clinical pregnancy rate were analyzed. Results Rescue ICSI was applied in 2 7 IVF cycles in which failed extrusion of the second polar body after conventional IVF was observed, and of them, complete failure to fertilize occurred in 23 IVF cycles. The fertilization rate and the normal fertilization rate for IVF （64.83% and 59.32%, respectively） were significantly lower than those for ICS1 （85.19% and 79.01%, respectively）, whereas the cleavage rate （94.12%） with IVF did not differ significantly from that with ICSI （95.65%, P〉0. 05）. The percentages of good-quality embryos in 1VF group （52. 67%） and 1CSl group （43.75%） also did not differ significantly （P〉0.05）. Although the rates of implantation and pregnancy appeared to be greater in IVF group （33.33% and 40.00%, respectively） compared with those in ICSI group （25.00% and 35. 71%, respectively）, the differences were not significant （P〉0.05）.Conclusions ICSI should be carried out for oocytes with abnormal zona pellucida, for which the risk of lVF failure is high. Rescue ICSI improves the likelihood of fertilization of oocytes with abnormal zona pellucida, but cannot improve the clinical outcome.
