Understanding the encapsulation and release processes of drug molecules using nanocarriers is vital for the development of nanoscale drug delivery.

The composition dependent electronic properties of the Mo 1Àx W x S 2 monolayer deposited over a TiO 2 (110) substrate were investigated based on ab initio density functional calculations by applying periodic boundary conditions. Adsorption of the Mo 1Àx W x S 2 monolayer on the TiO 2 is physical in nature based on calculated binding energy values. It was found that the mechanical strain generated by the presence of TiO 2 beneath the Mo 1Àx W x S 2 layer resulted in a shift in band position of the Mo 1Àx W x S 2 in favor of photoelectrochemical water splitting. Moreover, variation of W concentration in Mo 1Àx W x S 2 could improve the charge separation and increase the effective mass ratio leading to an extension of the electron-hole pair lifetime which is useful for photocatalytic and photoelectrochemical applications. † Electronic supplementary information (ESI) available: 2D proles of charge density difference, experimental and optimized lattice constants of TiO 2 and MS 2 (M ¼ Mo, W) and optimized atomic coordinates of Mo 1Àx W x S 2 /TiO 2 (110) and Mo 1Àx W x S 2 .

Numismatic data has always had a special place in archaeological studies. So, these documents can provide researchers with a wide range of information based on the focused point of research. The quality and quantity of elements used in coin metal can be restored by archaeometric studies. Some of these elements, such as silver, lead, copper and gold, indicate the monetary policies and metallurgy of their minting time. In this research, for the first time, 25 samples of coins in Ghajar periods were analyzed by the fast and non-destructive PIXE method with different minting techniques, and the percentage of main elements of these coins (silver, copper, lead, gold, iron, chlorine, calcium) were obtained. The results showed that silver is the mould element in this coinage and its amount is slightly different in hammering and milled coinages. Over time, the Qajars were able to gain more control over monetary policies. Also, the presence of small amounts of lead in most of the coins showed that the separation of elements has been done well by silver. And in this era, various sources have been used to supply the necessary silver for minting.
