1Anisole hydrodeoxygenation over Ni–Cu bimetallic catalysts: The effect of Ni/Cu ratio on selectivity显示文摘Sofia A. Khromova Andrey A. Smirnov Olga A. Bulavchenko Andrey A. Saraev Vasiliy V. Kaichev Sergey I. Reshetnikov Vadim A. Yakovlev 2014Applied Catalysis A, General2014,,:1
2Transitions between P21, P63 ( A), and P6a 22 modifications of SrAI2 04 by in situ high-temperature X-ray and neutron diffraction显示文摘Avdeev Maxim Yakovlev Sergey Yaremehenko Aleksey A 2007Journal of Solid State Chemistry2007,180,:1
3Real-time decay of fluorinated fullerene molecules on Cu(001) surface controlled by initial coverage显示文摘在这研究, C 60 Cu (001 ) 表面上的 F 18 分子借助于扫描通道显微镜学和密度被学习功能的理论计算。结果显示出那氟化的 fullerenes (塑造龟的极的 C 60 Cu (001 ) 上的 F 18) 腐烂从 C 60 笼子由 F 原子的一个一步一步的分队出现。当时,最有利的吸附配置被认识到 C 60 向 Cu 表面和六个 F 原子削尖的 F 18 从它被分开。结果也显示出那 C 60 F 12 分子强烈取决于起始的 C 60 F 18 范围。开始形成的分开的 F 原子一二维(2D ) 然后慢慢地转变了成导致 F 的表面的煤气的阶段组织。在 C 60 F 12 分子和 Cu (001 ) 出现取决于 2D 气体阶段的密度。因此,氟化的 fullerenes 的一生被 2D 气体阶段的密度决定,它被新导致 F 的结构的形成和 C 60 F 12 分子。Andrey I.

4Suppressing small-scale self-focusing of high-power femtosecond pulses显示文摘It was shown experimentally that for a 65-fs 17-J pulse,the effect of filamentation instability,also known as small-scale self-focusing,is much weaker than that predicted by stationary and nonstationary theoretical models for high B-integral values.Although this discrepancy has been left unexplained at the moment,in practice no signs of filamentation may allow a breakthrough in nonlinear pulse post-compression at high laser energy.Mikhail Martyanov Vladislav Ginzburg Alexey Balakin Sergey Skobelev Dmitry Silin Anton Kochetkov Ivan Yakovlev Alexey Kuzmin Sergey Mironov Ilya Shaikin Sergey Stukachev Andrey Shaykin Efim Khazanov Alexander Litvak 2023High Power Laser Science and Engineering2023,11,2:0
5Use of KDP crystal as a Kerr nonlinear medium for compressing PW laser pulses down to 10 fs显示文摘The input pulse of the laser PEARL with energy of 18 J and pulse duration of about 60 fs was compressed to 10 fs after passage through a 4-mm-thick KDP crystal and reflection at two chirped mirrors with sum dispersion of-200 fs^(2).The experiments were performed for the B-integral values from 5 to 19 without visible damage to the optical elements,which indicates that small-scale self-focusing is not a significant issue.It was shown that,by virtue of the low dispersion of the group velocity,the KDP crystal has some advantages over silica:a larger pulse compression coefficient,especially at a small value of the B-integral(B=5,...,9),lower absolute values of chirped mirror dispersion,and also a possibility to control the magnitude of nonlinearity and dispersion by changing crystal orientation.Andrey Shaykin Vladislav Ginzburg Ivan Yakovlev Anton Kochetkov Alexey Kuzmin Sergey Mironov Ilya Shaikin Sergey Stukachev Vladimir Lozhkarev Artem Prokhorov Efim Khazanov 2021High Power Laser Science and Engineering2021,9,4:0
