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...

A large finance literature has documented an important role for aggregate credit supply. However, there has only been a small amount of research on the role competition plays in influencing the overall importance of credit. This paper explores the possibility that changes in credit market...

This paper introduces a type of generalized two-barrier proportional step options. For a down-and-out step call, its payoff at expiration is defined as the payoff of an identical vanilla option discounted by a knock-out factor e-ρOTL,H , where OTL,H is the total duration of the underlying price...

Satellite data reveal that China has significantly increased its vegetation cover since 2000, and vegetation will maintain the increasing trend in the foreseeable future for becoming carbon neutral. However, limited work has examined the environmental impacts of vegetation greening because...

Comprehending the response of microbial communities in rivers along urbanization gradients to hydrologic characteristics and pollution sources is critical for effective watershed management. However, the effects of complex factors on riverine microbial communities remain poorly understood. Thus,...

Firm relations, which inform competitive environments of firms, are critical to firm operations and are often factored into investor decisions. Previous studies and practices have considered relatively stable and long-term business relations as an indicator of firm market value. Public news...
