Abstract
Background
Copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) can pose serious threats to environmental health because they tend to bioaccumulate in terrestrial ecosystems. We investigated under field conditions the transfer of these heavy metals in a soil-plant-snail food chain in Bana...... hiện toàn bộ

An efficient one pot method for the synthesis of α-alkoxymethylphosphonium iodides is developed by using PPh3/I2 combination at room temperature. Reaction conditions are found general to synthesize wide range of structurally variant alkoxymethylphosphonium iodides in high yield (70–91%). These new functionalized phosphonium salts are further used in stereoselective synthesis of vinyl ethers as wel...... hiện toàn bộ

A series of benzimidazole derivatives was developed and its chemical scaffolds were authenticated by NMR, IR, elemental analyses and physicochemical properties. The synthesized compounds were screened for their antimicrobial and antiproliferative activities. The synthesized benzimidazole compounds were evaluated for their antimicrobial activity using the tube dilution method and were found to exhi...... hiện toàn bộ

One of the main concerns for archaeo-metallurgists and archaeologists is to determine to what extent ancient craftsmen understood the effect of metal alloy composition and were able to control it in order to produce objects with the most suitable features. This problem can be investigated by combining compositional analyses of a high number of ancient artefacts with correlation analyses of the obj...... hiện toàn bộ
