    Abstract: The volume expansion of CoFe 2 O 4 anode poses a significant challenge in the commercial application of lithium/sodium‐ion batteries (LIBs/SIBs). However, metal–organic‐frameworks (MOF) offer superior construction of heterostructures with refined interfacial interactions and lower ion diffusion barriers in Li/Na storage. In this study, the CoFe 2 O 4 @carbon nanofibers derived from MOF are produced through electrospinning, in situ growth followed by calcination, which are then confined within an MXene‐confined MOF‐derived porous CoFe 2 O 4 @carbon composite architecture under alkali treatment. The CoFe 2 O 4 nanofibers anchor on the alkalized MXene that is decorated with the NaOH solution to form a multi‐pleated structure. The sandwich‐like structure of the composite effectively alleviates the volume expansion and shortens the Li/Na‐ion diffusion path, which displays high capacity and outstanding rate performance as anode materials for LIBs/SIBs. As a consequence, the obtained CoFe 2 O 4 @carbon@alkalized MXene composite anode shows satisfied rate performance at current density of 10 A g −1 for LIBs (318 mAh·g −1 ) and 5 A g −1 for SIBs (149 mAh g −1 ). The excellent cycling performance is further demonstrated at a high current density, where it maintains a discharge capacity of 807 mAh g −1 at 2 A g −1 after 400 cycles for LIBs and 130 mAh g −1 at 1 A g −1 even after 1000 cycles for SIBs.

    Abstract: It is challenging to fabricate durable and fluorine‐free superhydrophobic surfaces through simple procedures. In this study, a novel fabrication method for constructing robust, wearable, and fluorine‐free superhydrophobic surfaces on cotton textiles has been achieved via in situ growth of zeolitic imidazolate framework‐8 (ZIF‐8) layers followed by polydimethylsiloxane (PDMS) modification. The roughness created by the sheet‐like structure is optimized by tuning the mole ratio between 2‐methylimidazole and zinc nitrate during the in situ growth, while polydopamine (PDA) is introduced to improve the durability and stability. The resultant PDA/ZIF‐8/PDMS@cotton fabric exhibits a maximum water contact angle of 156.4° and a low sliding hysteresis angle of 3.8°. The as‐prepared superhydrophobic fabric also presents excellent durability and stability, and outstanding resistance against continuous sunlight exposure and various chemical reagents. In addition, the superhydrophobic surface possesses excellent self‐cleaning and anti‐fouling performance, as well as high separation efficiency 〉 97% and reusability when serving as a filter during the oil‐water separation. The proposed approach and prepared superhydrophobic fabric strongly demonstrate the potential applications in oil‐water separation with a prolonged life cycle.

    Abstract: Climate change poses a serious threat to biodiversity. Predicting the effects of climate change on the distribution of a species' habitat can help humans address the potential threats which may change the scope and distribution of species. Pterocarya stenoptera is a common fast‐growing tree species often used in the ecological restoration of riverbanks and alpine forests in central and eastern China. Until now, the characteristics of the distribution of this species' habitat are poorly known as are the environmental factors that influence its preferred habitat. In the present study, the Maximum Entropy Modeling (Maxent) algorithm and the Genetic Algorithm for Ruleset Production (GARP) were used to establish the models for the potential distribution of this species by selecting 236 sites with known occurrences and 14 environmental variables. The results indicate that both models have good predictive power. Minimum temperature of coldest month (Bio6), mean temperature of warmest quarter (Bio10), annual precipitation (Bio12), and precipitation of driest month (Bio14) were important environmental variables influencing the prediction of the Maxent model. According to the models, the temperate and subtropical regions of eastern China had high environmental suitability for this species, where the species had been recorded. Under each climate change scenario, climatic suitability of the existing range of this species increased, and its climatic niche expanded geographically to the north and higher elevation. GARP predicted a more conservative expansion. The projected spatial and temporal patterns of P. stenoptera can provide reference for the development of forest management and protection strategies.

    Abstract: The nanostructural evolution and mechanical properties during rolling with 30, 50, and 70% deformation of exceptional nano/microcrystalline 304 stainless steel prepared by the aluminothermic reaction casting method are investigated in this paper. The results of the microstructural evolution show that the grain size of the nano/sub‐micrograins have minor changes in which the volume fraction decrease dramatically, but the distribution of the nanograins become uniform with increased rolling deformation. The results of mechanical tests show that the increase in rolling deformation causes great increase in hardness and in yield strength from 274 to 364 HV and from 616 to 743 MPa, respectively. However, the tensile strength increases slightly from 925 to 995 MPa, and elongation decreases slightly from 24.5 to 21.9%. Conclusively, this work proves that an increase in rolling deformation causes a significant improvement in the hardness and strength and no considerable loss of the ductility in nano/microcrystalline 304 stainless steel.

    Abstract: Palladium (Pd), copper (Cu) bimetallic alloy nanoparticles immobilized onto a PDA‐coated graphene support (Pd−Cu/PDA/RGO) hybrid was synthesized through co‐reduction of K 2 PdCl 4 and Cu(NO 3 ) 2 . The Pd to Cu ratio was rationally controlled to obtain the optimum Pd−Cu/PDA/RGO catalyst. The as‐prepared catalyst demonstrated good catalytic activity for hydrogen production by hydrolysis of ammonia borane, high turnover frequency (TOF) of 37.41 mol H 2 per mol Pd −1 min −1 at 298 K and a low activation energy (E a ) of 47.97 kJ mol −1 were accomplished, these metrics were superior to that of Pd−Cu/RGO nanocatalysts. The comparative results indicate that the PDA‐coated graphene (PDA/RGO) support is pivotal for the catalytic activity of Pd−Cu/PDA/RGO for hydrolysis of ammonia borane. The PDA modified onto GO surface effectively disperse the alloy particles, therefore ensure more catalytic active sites responsible for ammonia borane hydrolysis. The tight anchoring of alloy nanoparticles also enabled excellent cyclic stability, 67.7 % of its initial catalytic activity could be maintained after ten cycles. The current work demonstrates the potential of Pd−Cu/PDA/RGO in active and durable ammonia borane hydrolysis for hydrogen production.

    Abstract: The zinc cobaltite possesses merit of high theoretical specific capacity. However, issues of low conductivity and volume expansion during lithiation and delithiation lead to severe capacity fading. In this work, a porous zinc cobaltite/carbon composite nanofiber is synthesized with a metal–organic frameworks (MOFs) structure through electrospinning, in situ growth, and hydrothermal reaction. The obtained zinc cobaltite/carbon composite nanofibers have an improved specific surface area (90.61 m 2 g ‐1 ), enabling excellent electrochemical performance as anode materials in Li‐ion batteries. Briefly, a high initial discharge capacity of 2468 mAh g ‐1 and reversible capacity of 2008 mAh g ‐1 after the 200 cycles, and an outstanding rate capability of 937 mAh g ‐1 at 2 A g ‐1 are achieved. The capacity fading of MOFs–zinc cobaltite/carbon composite nanofibers is significantly improved, which can be attributed to the following reasons: i) the MOFs structure effectively relieve the strain stemming from volume expansion of transition metal; ii) the abundance of mesoporous structure facilitates the electron transport for Li + diffusion rate by shortening the Li‐ion diffusion path during lithiation/delithiation process; iii) the carbon nanofibers with excellent conductivity enable efficient conduction efficiency of lithium ions and electrons. The proposed strategy offers a new perspective to prepare high‐performance electrode for lithium‐ion batteries.
