Efficient photosensitized oxygenations in phase contact enhanced microreactors.
A transparent dual-channel microreactor with highly enhanced contact area-to-volume ratio was fabricated for efficient photosensitized oxygenations. The dual-channel microreactor shielded with polyvinylsilazane (PVSZ) consisting of an upper channel for liquid flow and a lower channel for O(2) flow, allows sufficient phase contact along the parallel channels through a gas permeable PDMS membrane...
متن کاملTriple-channel microreactor for biphasic gas–liquid reactions: Photosensitized oxygenations
A triple-channel microreactor fabricated by means of a soft-lithography technique was devised for efficient biphasic gas-liquid reactions. The excellent performance of the microreactor was demonstrated by carrying out photosensitized oxygenations of α-terpinene, citronellol, and allyl alcohols.
متن کاملPhotoacoustic and photothermal detection of photosensitized oxygenations
Study of relaxation processes of excited states of hematoporphyrin IX QW) solutions (in ethanol and methanol) in the presence of tetramethyl ethylene chemical acceptor using both the photoacoustic (PA) microphone and photothermal (PT) PZT detection, is described. A significant difference between PA and PT signal behaviour has been observed when extremely low (down to 1.25 pM, PT measurements) a...
متن کاملsynthesis of platinum nanostructures in two phase system
چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Anisotropic Spin -Lattice Relaxation of Deuterated Hexamethylbenzene
The anisotropic spin-lattice relaxation of deuterated hexamethy lbenzene (HMB-d,,) was measured at -36 and 70°C. The anisotropy is due to the anisotropic sixfold reorientation of the molecule about its hexad axis, and a model is presented to explain quantitatively the anisotropy, considering only single-particle relaxation. The temperature dependence of T, was measured, and the activation energ...
