On June 30, 2022, the Organization for Economic Cooperation and Development OECD published six new Test Guidelines and ten updated or corrected TGs, including the first two harmonized methods for measuring certain nanomaterial-specific physical-chemical properties.

ArcGIS software was used to analyze the spatial distribution of Mid Holocene (i.e., 6.7-3.1 ka BP) human settlements and sites in the Dalian area. Their evolution was studied in depth alongside the Mid Holocene environmental background known to have existed. The results showed that: ① The number of ancient settlements in the Dalian area increased during this period. Most sites during the three periods studied were to be found 0 to 50 m above sea level (asl), with a significant increase in the ...

Novel coating consisting of zinc oxide and silver nanoparticles used to modify healing abutments which can be used as drug delivery systems in oral implantology

Dust particle studies in ice cores from the tropical Andes provide important information about climate dynamics. We investigated dust concentrations from a 22.7 m ice-core recovered from the Quelccaya Ice Cap (QIC) in 2018, representing 14 years of snow accumulation. The dust seasonality signal was still preserved with homogenization of the record due to surface melting and percolation. Using a microparticle counter, we measured the dust concentration from 2–60 μm and divided the annual dust ...

Heatwaves at both poles have alarmed climate experts, who have warned that the "unusual" phenomena might indicate a quicker and more catastrophic climate collapse. Temperatures in Antarctica touched record highs over the weekend, reaching up to 40 degrees Celsius above average in some locations
