An innovative solar concentrating beam splitting photovoltaic thermal (CBS-PVT) system using a half-trough concentrator (HTC) and a film spectrum filter (FSF) is proposed and studied in this study. The FSF used for this system is designed and its average reflectivity and transmissivity are 0.272 and 0.

Article Synopsis
  • Flavonoids, particularly 7,8-dihydroxyflavone (7,8-DHF) and 7-hydroxyflavone (7-HF), were studied for their antioxidant properties in RAW264.7 cells subjected to oxidative stress.
  • Using various assays, the study found that 7,8-DHF exhibited stronger antioxidant effects than 7-HF by reducing reactive oxygen species (ROS) and malondialdehyde (MDA) levels while enhancing superoxide dismutase (SOD) activity.
  • The mechanisms revealed that 7,8-DHF inhibited cellular damage pathways and boosted protective proteins, indicating its potential as a drug to combat oxidative stress injuries.

The treatment of polluted water is a serious environmental problem in the world. Biomass is easily modified and can be prepared into adsorbent materials, which is expected to solve the problem of heavy metal ion adsorption in sewage. In this paper, esterified tobacco straw based hydrogels (ETS-PAA) were synthesized from waste tobacco straw biomass.

This paper aims at facilitating the developments of solar photovoltaic (PV) power and wind power generations to reduce carbon emission and achieve the carbon neutralization. The main novelty of this study is developing a new partnership comprised by the green energy investment company (GEIC), solar power plant (SPP), and offshore wind power plant (OWPP) and analyzing the impacts of typical factors on the coordinated development of SPP and OWPP based on the evolutionary game theoretical method. By using a tripartite evolutionary game model, the stability analysis of equilibrium strategy is carried out.

In this work, a porous tobacco straw-based polyacrylic acid hydrogel STS-PAA with high adsorption performance was prepared by polymerizing pretreated waste tobacco straw (TS) with acrylic acid/potassium acrylate by UV radiation initiation. The adsorption performance of metal ions was investigated. The effects of different temperatures (25°C, 35°C, and 45°C), adsorption times (1-420 min), pH values (2.

Mitochondria-targetable fluorescent chemosensors, Rhodamine-B and rhodamine 6G bearing syringaldehyde based receptors were designed and synthesized for efficient chemosensing of Zinc(II) ions. The probes showed the very selective naked eye color change to pink from colorless upon addition of Zinc(II) ions, further these probes showing turn-on fluorescence enhancement with Zn(II) ions by opening of rhodamine spirolactam. The probes are very sensitive towards Zn(II) ions among other ions.

Solar thermal power and nuclear power generations are two most promising clean energy power approaches, which are effective for reducing carbon emissions. In order to promote the coordinated development of solar thermal power and nuclear power in China under the background of carbon neutral, the current paper develops a partnership comprised by the energy investment company (EIC), solar thermal power plant (STPP) and nuclear power plant (NPP). By utilizing the evolutionary game theory method and current policies of China, the evolutionary process simulations of the three participants under different conditions are conducted, which demonstrate that steady states could be achieved under different partnerships.
