We use compatibility of O-plane action with nonlinear T-duality as a guiding principle to find all NS-NS couplings in the O-plane action at order $\\alpha'^2$. We find that the dilaton couplings appear in the string frame only via...

ZnO nanoparticles were synthesized by the sol-gel method. The nanoparticles were added to polyvinyl alcohol (PVA) biopolymer to compare the microstructural, mechanical, antibacterial and physical properties of bionanocomposite films reinforced...

RC(O)NHP(O)X2, are potential O,O\\'-donor ligands for metal complexation, particularly for lanthanide ions.

Following the previous works about carbacylamidophosphates with a C(═O)NHP(═O) skeleton such as P(O)[NHC(O)C6H4(4-F)][HNC6H4CH3]2 and P(O)[NHC(O...

with the usual vertex operators are not gauge invariant, the above amplitudes are invariant. From the amplitude describing scattering of two NS-NS states off the O-plane, we find the low energy effective action of O-planes. The result shows a relative factor 2^{p...
