This paper studies the role of ownership structure in determining the relationship between firm characteristics and credit constraints affecting firm level investment. Firm size is a significant determinant of credit constraints in case of business group un-affiliated firms, domestic firms, and...

Using a quasi-natural experiment and the city-level panel data from 2009 to 2018 in China, this paper investigates the impact of broadband infrastructure on green total factor energy efficiency. Results show that the policy intervention of Broadband China has significantly improved the green...

We study the question whether a holder of standard essential patents (SEPs) should be allowed to choose the level in the value chain at which to offer a FRAND license to its SEPs. We give a pos-itive answer to this question for two reasons. First, the SEP holder and the social planner tend to...

Phosphate fertilizer and artificial humic substances are jointly applied to a model soil, and maize growth and the soil phosphorus availability are determined at various A-HS concentrations in greenhouses using the root-bag technique. A-HS structure was varied to include different species...

Cobalt-based catalysts have been widely explored in the degradation of organic pollutants based on peroxymonosulfate (PMS) activation. Herein, we report an MXene nano-Co3O4 co-catalyst enriched with oxygen vacancies (Ov) and steadily fixed in nickel foam (NF) plates, which is used as an...

Exciplex-thermally activated delayed fluorescence (exciplex-TADF) system is an excellent candidate for fabrication of high-efficiency organic light-emitting diodes (OLEDs) because of its more easily achieved small singlet–triplet energy splitting (Δ E ST ) and doping-control. However,...

Photocatalysis is considered an economical, environmentally friendly, and effective technology for removing pollutants. The construction of Z-Scheme heterojunctions has been identified as one of the feasible solutions capable of enhancing the photocatalytic activity. Herein, a series of visible...

Five runs of bench test for bioethanol production in membrane bioreactor with pervaporation or membrane distillation have been carried out for the evaluation of technology performances. Compared with the traditional batch mode, the equipment utilization efficiency can be increased to 1.5-2.0...

The main objective of the research is to measure the economic efficiency of sheep rearers in Al-Hasakah Governorate using the data envelopment analysis method. The sample size was 313 rearers, who were selected by random sampling method from the administrative regions of Al-Hasaka Governorate....
