Magnetic field effects on near-infrared optical properties of cytochrome oxidase
This paper reports the possible effects of intense magnetic fields on the near-infrared optical properties of cytochrome oxidase. Optical measurements performed on both cytochrome aa3 suspension and in vivo showed changes in optical absorbance at 690–830 nm under magnetic field exposure. Magnetic fields of up to 14 T generated by a superconducting current were able to change the oxidation of th...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولKinetic Observations on the near Infrared Band of Cytochrome C Oxidase.
Although it has been more than 25 years since Keilin and Hartree (1, 2) noted that their preparations of cytochrome oxidase contained copper, its relation to the function of the enzyme continues t.o be a matter for discussion. The first titrat,ions of the reduced enzyme with oxygen, performed by Chance and Yonetani (3), seemed to exclude copper as an electron donor since 1 molecule of oxygen wa...
متن کاملNear-infrared chiro-optical effects in metallogels.
A series of novel metallogelators containing near-IR nickel-bis(dithiolene) absorbers were rationally designed and synthesized. Robust gel networks are formed by right handed helical 1D-nanofibers which generate strong and remarkable chiro-optical effects in the near-infrared region.
متن کاملNear-infrared time-resolved optical absorption studies of the reaction of fully reduced cytochrome c oxidase with dioxygen.
Electron transfer during the reaction of fully reduced bovine heart cytochrome oxidase with dioxygen has been studied at 24 degrees C in the near-infrared region following photolysis of the fully reduced CO-bound complex. The transient spectral changes and kinetics were followed on microsecond to millisecond time scales at nine different wavelengths between 597 and 935 nm and were analyzed usin...
