In this study, functional elements coatings on Ti-6Al-4V alloy by plasma electrolytic oxidation for biomaterials were studied using various experimental techniques. For this study, Ti-6Al-4V ELI disk (grade 5, Timet Co. Ltd., Japan diameter; 10 mm) were used as the substrate for PEO treatment in the electrolyte containing Ca, P, Si, Zn, and Mn ions. The PEO treatment was performed using a pulsed DC power supply at 280 V for 3 min. The PEO-treated surface was observed with field-emission scanning electron microscope (FE-SEM), and energy dispersive X-ray spectrometry (EDS; Oxford ISIS 310, England), Image Analyzer software, and X-ray diffractometer (TF-XRD, X'pert Philips, Netherlands). The number of pores increases, as the Zn ion content increases. And the number of pores decrease, as the Mn ion content increases. The addition of Zn and Mn ions affects the number and size of pores and the area occupied by the pores. Mn and Zn are distributed around pores and in the pores. Anatase and rutile peaks appear and the HA peak shifted to the left in the case of Mn and Zn ion additions.

This study shows the efficiency of WH-C450, an adsorbent obtained from water hyacinth (WH) biomass, in the removal of sulfamethoxazole (SMX) from aqueous solutions. The process involves calcination of WH at 450 °C to produce an optimal adsorbent material capable of removing up to 73% of SMX and maximum SMX adsorption capacity of 132.23 mg/g.

The ecological niche separation of microbial interactions in forest ecosystems is critical to maintaining ecological balance and biodiversity and has yet to be comprehensively explored in microbial ecology. This study investigated the impacts of soil properties on microbial interactions and carbon metabolism potential in forest soils across 67 sites in China. Using redundancy analysis and random forest models, we identified soil pH and dissolved organic matter (DOM) aromaticity as the primary drivers of microbial interactions, representing abiotic conditions and resource niches, respectively.

The jute hairy caterpillar, Spilosoma obliqua (Lepidoptera: Erebidae) is considered as one of the major threats to jute cultivation. The best eco-friendly methods to combat these jute pests involve administration of nano-biopesticides, as a successful alternative to the toxic chemicals. In this study, a nano-biopesticide formulation containing green synthesized silver nanoparticles (Ag NPs) using Ocimum sanctum leaf extract has been proposed.

The Laser Interferometer Space Antenna (LISA) mission is designed to detect space gravitational wave sources in the millihertz band. A critical factor in the success of this mission is the residual acceleration noise metric of the internal test mass (TM) within the ultra-precise inertial sensors. Existing studies indicate that the coupling effects of residual gas and temperature gradient fluctuations significantly influence this metric, primarily manifesting as the radiometer effect and the outgassing effect.
