Published 2001Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: With better than 1% control of alloy composition, binary alloy films CoxNi1−x/Cu(100) with x≤10% were prepared for the study of the spin-reorientation transition at variations of composition, thickness, and temperature. Only the films with a Co concentration less than 10% reveal the spin-reorientation with the film thickness. The critical thickness for the spin-reorientation transition was shifted drastically from 7.5 to 17.5 monolayers for a Co concentration variation from 0% to 8%. These findings indicate a strong influence of the composition on the magnetoelastic anisotropy. A kind of temperature-driven spin-reorientation from in-plane to perpendicular with increasing temperature was also found. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The magnetic and structural properties were investigated for the 2 ML Co/Cu(100) films grown at various temperatures from 125 to 350 K. By precisely controlling the film thickness, the influence of thickness on Curie temperature (TC) due to the finite size effect can be excluded. The Curie temperature of the 2 ML Co keeps almost invariant for the growth temperature (Tg) below 250 K, and drops drastically at Tg higher than 275 K. For Tg=340 K, TC dropped to 170 K which is only about half of 325 K for Tg=125 K. Accompanied with the increase of TC for the films grown at lower temperatures, the remanent Kerr signal as well as coercivity were enhanced. According to a simple theoretical estimation, the change of TC due to the variation of the magnetization and anisotropy was found to be consistent with the experimental results. The enhancement in TC or magnetization and anisotropy with various Tg should be traced back to the presence of island growth in the films grown at lower temperatures. © 2001 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1994Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: The photodissociation processes of CH3SSCH3 at 248 and 193 nm and CH3SCH3 at 193 nm have been studied by translational spectroscopy. When excited at 248 nm, CH3SSCH3 undergoes a simple S–S bond scission to produce two CH3S fragments with an average translational energy of 33 kcal/mol. The angular distribution of the product with respect to the polarized laser is measured and fitted with an anisotropy parameter β=1.2. It indicates that the dissociation is a fast, direct process. At 193 nm, there is only a simple dissociation channel for CH3SCH3, while CH3SSCH3 undergoes a predominant C–S bond scission with the S–S bond scission as a minor channel. No angular dependence for the primary products from both CH3SCH3 and CH3SSCH3 has been observed. The observation of S+2 time-of-flight spectra shows that a major fraction of CH3S2, which is internally excited when produced, undergoes spontaneous dissociation to form slow S2 and CH3 radicals. Results obtained for the dissociation processes of both molecules at 193 nm are rationalized and comparisons with previous investigations [J. Chem. Phys. 92, 6587 (1990); 95, 5014 (1991)] are also included.Type of Medium: Electronic ResourceURL: -

Published 1998Staff ViewISSN: 1365-2044Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Forty patients without eye disease, undergoing elective nonophthalmic surgery, were studied in a double-blind, randomised, placebo-controlled study evaluating the efficacy of mivacurium pretreatment in attenuating the rise in intra-ocular pressure in response to suxamethonium administration, laryngoscopy and intubation. The patients were randomly allocated to receive either mivacurium 0.02 mg.kg−1 or normal saline as pretreatment 3 min before a rapid sequence induction technique using alfentanil, propofol and suxamethonium. Suxamethonium induced a significant increase in intra-ocular pressure in the control group but not in the mivacurium pretreatment group (mean (SEM) increase = 3.5 (1.2) mmHg vs. 0.4 (0.8) mmHg, p 〈 0.05). There was a decrease in intra-ocular pressure in both groups after laryngoscopy and intubation with no significant difference between the two groups. These results show that mivacurium pretreatment is effective in preventing the increase in intra-ocular pressure after suxamethonium administration.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-2044Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: We conducted a double-blind, randomised, placebo-controlled study evaluating the efficacy of prophylactic metaraminol for preventing propofol-induced hypotension. Thirty patients aged 55–75 years undergoing general anaesthesia were randomly allocated to receive either metaraminol 0.5 mg or saline before administration of fentanyl 1 µg.kg−1 and propofol 2 mg.kg−1. Induction of anaesthesia was associated with a decrease in mean and systolic arterial pressure in both groups (p = 0.0001). However, there was no significant difference between the two groups. These results show that prophylactic use of metaraminol 0.5 mg does not prevent the decrease in blood pressure following fentanyl and propofol induction in older patients.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: The photodissociation of S2Cl2 at 248 and 193 nm has been studied by translational spectroscopy. Upon excitation at 248 nm, S2Cl2 undergoes predominantly the dissociation channels to form the products, (1) S2Cl+Cl and (2) SCl+SCl. The relative yield of (1)/(2) was determined at ∼3.0:1.0. The S2Cl+Cl products were detected with two separate product translational energy distributions of 〈Et〉=14 and 41 kcal/mol. The slow S2Cl fragment, which is internally excited, undergoes a secondary dissociation to form S2+Cl. Dissociation mechanisms which are consistent with the isotropic recoiling are proposed: the slow component could arise from the ground electronic state while the fast component would more likely originate from a mixed excitation of 1A and 1B states (C2 symmetry). The SCl product with anisotropy parameter β=1.6, on the other hand, should proceed by an excited 1B state. At 193 nm, a three-body formation of S2+2Cl becomes the more efficient process than the simple S–Cl or S–S bond fission. Assuming that the rupture of both S–Cl bonds occurs in a single kinetic step, a P(Et) distribution with 〈Et〉=30 kcal/mol is determined. Because of the measured β=−0.3 for the formation of triple products, a higher 1B state will be involved in the excitation. © 1999 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1986Staff ViewISSN: 1089-7690Source: AIP Digital ArchiveTopics: PhysicsChemistry and PharmacologyNotes: A total of 37 absorption bands, lying between 3785 and 4805 A(ring), have been observed during the pyrolysis of S2Cl2 at 750 K. These bands have been tentatively assigned to transitions between the X˜ A‘ state of S2Cl to an unidentified electronically excited state with vibrational frequencies ω'1 =480 cm−1 and ω2 =407 cm−1. From this assignment it follows that the ground state vibrational frequencies are ω‘1 =659 cm−1, ω‘2 =600 cm−1, and ω‘3 =336 cm−1. A simple molecular orbital diagram has been constructed from the frontier orbitals of S2 and Cl. The predicted changes in the bond strengths and bond angles between the ground state and the excited state are consistent with experimental assignments.Type of Medium: Electronic ResourceURL: -
