The successful functioning of global stock index futures markets depends heavily upon the efficient execution of two essential recurring transactions: calendar spreads and stock index arbitrage. In the final weeks preceding a futures expiration calendar transactions dominate order flow in a...

Plastics biodegradation by insect larvae is regarded as an emerging strategy for the disposal of resistant plastic wastes. Larvae of superworms (Zophobas atratus Fab.) and mealworms (Tenebrio molitor Fab.) can survive on sole plastic diets. However, no side-by-side comparison of plastics...

Developing high-performance energy storage materials is crucial to alleviate the energy crisis. Recently, newly experimentally synthesized graphene derivatives, four-nitrogen coordinated transition-metal embedded graphene (TMN4-G), have attracted considerable attention as sensitive material and...

Background: Per- and polyfluoroalkyl substances (PFASs) questions have become increasingly prominent in the fields of ecotoxicology and public health. More crucially, exposure to long-chain PFASs frequently produces developmental toxicity, prompting the large-scale production and use of...

In this work, a series of ordered mesoporous carbon nanomaterials (CMK-3) have been synthesized by a hard-template method at temperatures of 80 o C, 100 o C and 130 o C, which can serve as adsorbents for efficient quinolones adsorption in aqueous solutions. The physicochemical properties and the...

Flexible rechargeable batteries are urgently needed because of the rapid development of wearable electronics. However, most lithium-ion batteries fail to meet safety and stretchability requirements, which are critical to the practical application of such devices. Herein, a freestanding,...

Flexible and wearable energy devices have become an important support and indispensable product of the era of artificial intelligence and Internet of Things. Enzyme biofuel cells (EBFCs) have received much attention for their ability to convert the body's abundant biochemical energy into...

Copper and iron play an important role in many biological processes in humans, animals and plant life. Hence, it is critical to observe the cupper and iron ions concentration by a precise, fast, selective and an applied method. Herein, a multifunctional cellulose-based smart fluorescent material...

A novel pH-responsive carbon-based nano-adsorbent (MGO-CNT@β-CS-CD) for the adsorption of dyes from aqueous solution was prepared by using graphene oxide, Fe3O4, multi-walled carbon nanotubes, β-cyclodextrin and Chitosan as raw materials. The structure and adsorption mechanism of adsorbent...

To understand the responses of insect larvae gut-microbiomes to plastics ingestion, superworm Zophobas atratus and mealworm Tenebrio molitor were fed with either polyethene (PE) or polystyrene (PS) foam as sole diet for a period of 45 days, sole bran diet was used as controls. Rapid declines of...
