A series of unsupported and supported vanadium phosphorus oxide catalysts were prepared by employing a new strategy, which significantly reduced the complexity of catalyst preparation. The greatly simplified catalyst fabrication benefits a greener and lower-cost process for practical applications. The currently fabricated systems showed ca. 90% target product(s) selectivity with a promising yield as well as catalyst durability.

Vanadium flow batteries (VFBs), as a high-safety grid-scale energy storage technology, provide an ideal solution for storing green power generated from intermittent renewable energy sources. However, the sluggish kinetics of the V/V redox reaction at the negative electrode interface limits the development of VFBs toward high-rate performance. Herein, density functional theory (DFT) calculations demonstrate the feasibility of phosphorus (P) atom modulation on the electronic structure at the N, O dual-doped carbon interface.

Wetlands play an important role in biogeochemical cycles, as their hydrological and edaphic properties drive chemical reactions that facilitate the storage or transfer of various elements. Some herbaceous wetlands are ecosystems dominated by grass-like communities, sedges and rushes, and the information available at international level reveals they are poorly studied ecosystems in terms of elemental analysis. This research seeks to contribute to the understanding of herbaceous wetlands producing an inventory of essential and non-essential elements, the latter expected to be increased from the direct interaction of the wetland with a road.

To evaluate the peri-implant bone repair of implants manufactured from commercially pure titanium (cp-Ti) or titanium-aluminum-vanadium alloy (Ti-6Al-4 V) with machined (MS) or laser-modified (LS) surfaces. Implants (n = 192) were installed in the tibias of 96 rats and divided according to the implant installed: (1) cpMS: cp-Ti with an MS surface, (2) cpLS: cp-Ti with an LS surface, (3) alloyMS: Ti-6Al-4 V with an MS surface, and (4) alloyLS: Ti-6Al-4 V with an LS surface. Scanning electron microscopy-energy dispersive X-ray (SEM-EDX) analysis was performed prior to implant placement.

Artemisia species are known for their rich phytochemical diversity; however, their ability to accumulate a wide range of minerals and metals from the soil raises significant safety concerns, particularly in therapeutic and dietary contexts. This review provides data on elemental composition across 64 Artemisia species, evaluating their nutritional, medicinal and environmental implications. Data collection was carried out using various databases, including SciELO, Google Scholar, Medline, ScienceDirect, PubMed, Web of Science and Scopus.

In previous studies, most transmissive THz linear polarization rotators based on these materials are complicated in structure or suffer from poor performance, such as low transmittance and modulation depth. In this paper, we present a tunable transmissive THz linear polarization rotator based on VO.
