High selective hydrocarbon and hydrogen products from catalytic pyrolysis of rice husk: Role of the ordered mesoporous silica derived from rice husk ash for Ni-nanocatalyst perform... by Pham, Le Kim Hoang, Alsaiari, Mabkhoot, Thao, Bui T. Thu, Hieu, Nguyen Huu, Phuc Hoang Duy, Nguyen, Vo, Dai-Viet N., Witoon, Thongthai, Nguyen, Van Cuong, Kongparakul, Suwadee, Samart, Chanatip, Trinh, Thanh H., Al-Gheethi, Adel

“…This study successfully synthesized ordered mesoporous silica using a sodium silicate solution derived from high-purity silica extracted from rice husk (98.09%), aiming to catalyst support for integrating fast catalytic upgrading of rice husk. The ordered mesoporous silica, including MCM-41 and KIT-6, were synthesized by co-assembly with additional surfactants, consisting of Cetyl trimethylammonium bromide (CTAB) and Pluronic P123, respectively. …”

100 THz optical switching with plasmonic metamaterial by Venkatram, Nalla, Stefano, Vezzol, João, Valente, Sun, Handong, Nikolay, Zheludev

“…In coherent perfect absorption, the interference of two counter-propagating coherent beams on a highly absorbing material of sub- wavelength thickness can either lead to nearly total transmission or to nearly total absorption of the incident light, depending on their mutual intensity and phase.1 A device based on coherent absorption has the advantage of being compact, fast, and intrinsically low power while demonstrating large modulations of light. …”

Towards deep neural networks robust to adversarial examples by Matyasko, Alexander

“…To address the above limitations, we propose a primal-dual proximal gradient attack algorithm. Our attack is fast and accurate. We directly solve the attacker's problem for any Lp-norm for which the proximal operator can be computed in the closed-form. …”

NiMn-based bimetal-organic framework nanosheets supported on multi-channel carbon fibers for efficient oxygen electrocatalysis by Cheng, Weiren, Lu, Xue Feng, Luan, Deyan, Lou, David Xiong Wen

“…X-ray absorption fine structure (XAFS) spectroscopy and density functional theory (DFT) calculations reveal that the strong synergetic effect of adjacent Ni and Mn nodes within MCCF/NiMn-MOFs effectively promotes the thermodynamic formation of key *O and *OOH intermediates over active NiO6 centers towards fast ORR and OER kinetics.…”

Low-energy channel for mass transfer in Pt crystal initiated by molecule impact by Babicheva, Rita I., Evazzade, Iman, Korznikova, Elena A., Shepelev, Igor A., Zhou, Kun, Dmitriev, Sergey V.

“…This is explained by the fact that the atom can initiate only a very sharp, fast-moving crowdion (anti-kink), which requires relatively high energy, while the molecule is able to initiate a less localized crowdion with considerably lower velocity and energy. …”

Erasure temperature measurements of heat assisted magnetic recording media by Chen, Y. J., Yang, H. Z., Leong, S. H., Cher, K. M., Hu, J. F., Sethi, P., Lew, Wen Siang

“…The temperature for complete erasure at laser power, Pw = 72 mW for the LH method, corresponds therefore to ∼650 K (≈Te) for the bulk heating methods. Besides fast measurement, LH (as a comparable and viable approach for erasure measurement) is dynamic, localized, and has time scales closer to practical HAMR situation.…”

Influence of operating parameters on morphology of laser hardened surfaces by Maharjan, Niroj, Zhou, Wei, Zhou, Yu, Wu, Naien

“…The highly intense laser beam rapidly heats up the irradiated surface above its austenitization temperature which cools down instantaneously (self-quenching) as the laser moves away from the spot producing a hardened surface. The fast heating and cooling generate a non-equilibrium phase transformation of which very little is understood. …”
