Narrowing Plasmon Resonance Linewidth of Au Nanodome Lattices
Zhang, Jinlin,Ko, Woo Ri,Long, Fei,Lee, Min Hyung,Suh, Jae Yong American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.44
<P>Gold hollow nanodomes arranged in hexagonal lattices support surface plasmon polaritons (SPPs) propagating at air-Au interface. The cross-sectional heights of the continuous and hierarchical hexagonal nanodome arrays can be altered by a simple thermal treatment, and the change in nanodome size leads to a significant linewidth narrowing of plasmon resonance because of reduced scattering loss. Taking the variation in the SPP intensities into account, the surface modulation depth is found to be around 100 nm for achieving a longer propagation length of SPP.</P>

Background/Aims: Four-week treatment of linvencorvir (RO7049389) was generally safe and well tolerated, and showed anti-viral activity in chronic hepatitis B (CHB) patients. This study evaluated the efficacy, safety, and pharmacokinetics of 48-week treatment with linvencorvir plus standard of care (SoC) in CHB patients. Methods: This was a multicentre, non-randomized, non-controlled, open-label phase 2 study enrolling three cohorts: nucleos(t)ide analogue (NUC)-suppressed patients received linvencorvir plus NUC (Cohort A, n=32); treatment-naïve patients received linvencorvir plus NUC without (Cohort B, n=10) or with (Cohort C, n=30) pegylated interferon-α (Peg-IFN-α). Treatment duration was 48 weeks, followed by NUC alone for 24 weeks. Results: 68 patients completed the study. No patient achieved functional cure (sustained HBsAg loss and unquantifiable HBV DNA). By Week 48, 89% of treatment-naïve patients (10/10 Cohort B; 24/28 Cohort C) reached unquantifiable HBV DNA. Unquantifiable HBV RNA was achieved in 92% of patients with quantifiable baseline HBV RNA (14/15 Cohort A, 8/8 Cohort B, 22/25 Cohort C) at Week 48 along with partially sustained HBV RNA responses in treatment-naïve patients during follow-up period. Pronounced reductions in HBeAg and HBcrAg were observed in treatment-naïve patients, while HBsAg decline was only observed in Cohort C. Most adverse events were grade 1–2, and no linvencorvir-related serious adverse events were reported. Conclusions: 48-week linvencorvir plus SoC was generally safe and well tolerated, and resulted in potent HBV DNA and RNA suppression. However, 48-week linvencorvir plus NUC with or without Peg-IFN did not result in the achievement of functional cure in any patient.

Data generated by various fields are increasing exponentially and thus results in challenges for data performances in both scales of diversity and complexity. The problem how to solve the bottlenecks of low -bandwidth networks has been of fatal significance for all kinds of network status. We present a new approach on improved optimization for data disaster recovery system (DDRS) over low-bandwidth networks that not only aims to improve the defects and deficiencies of mainstream DDRS but also helps ensure the reliable network resources for operators to conduct multi-services. A novel bandwidth self-adaptive approach (BSAA) for data packing replication was essentially established to make contribution to the integral performance improvement. A Hidden Markov Model (HMM) for predicting network status was also built to ensure system availability and stability. Experiments showed that the DDRS over low-bandwidth networks named InfoDr can effectively optimize the workload with better performance and better application self-adaptability for multi-services. Keywords: Data Disaster Recovery System; Low-bandwidth network; Deduplication

This paper focuses on the stability of three homodromy vibrators in a vibrating system with two rigid frames (RFs). The motion differential equations of the system are established. Using the average method yields the average coupling torque balanced equations of three vibrators, and the simplified analytical expressions for synchronization and stability criterions of the system were derived. The coupling dynamic characteristics were numerically analyzed, including frequency-amplitude response, stable phase differences, synchronization and stability ability, and phase relationships. The simulations to verify the validity of theoretical results were carried out. It is shown that the stable states of the system are classified into three types, thereof the stability of phase differences among vibrators is similar in sub-resonant and super-resonant states, which results in no vibration of the system. While in near sub-resonant state the system reflects strong useful positive superposition vibration with energy saving, which is exactly the desire in engineering design.

In this paper, we study the intrinsic coherence resonance of neurons due to ion channel noise under an external stimulus. We find that the external stimulus cannot only increase the spiking coherence of neurons but also increase the optimal area of neuronal membrane for maximal spiking coherence. The optimal membrane area is approximately 3 μm<sup>2</sup> without the external stimulus. However, when the external stimulus is 6 μA/cm<sup>2</sup>, the optimal membrane area is approximately 400 μm<sup>2</sup>. Because 400 μm<sup>2</sup> is the area of a common neuronal soma, our finding has a realistic meaning. Under the external stimulus, common neurons have an optimized conformation to guarantee maximal spiking coherence and the best sub-threshold signal encoding.
Interfacial Mode Interactions of Surface Plasmon Polaritons on Gold Nanodome Films
Ko, Woo Ri,Zhang, Jinlin,Park, Hyeong-Ho,Nah, Junghyo,Suh, Jae Yong,Lee, Min Hyung American Chemical Society 2016 ACS APPLIED MATERIALS & INTERFACES Vol.8 No.32
<P>Hollow metallic nanodome structures were fabricated using anodized aluminum oxide (AAO) nanopores as deposition and sacrificial templates. Individual Au nanodomes inherit the unique shapes of the well-defined AAO membranes whose pedestal cells become square or hexagonal lattices with hemispheres in close proximity. Minimal contact between the hollow nanodomes and the glass substrate provide an identical dielectric medium across the film. The nanodome Au films support surface plasmon polaritons (SPPs) of strong air-Au and weak Au-glass modes in the light transmission dispersions. The mode crossings of distinct SPPs exhibit characteristic energy gaps, which depend on the periodic geometries of the nanostructures.</P>

A high resolution aeromagnetic survey of Kalatage area was carried out, aimed at providing detailed geological structures information and guiding for further mineral prospecting. The recently acquired data was processed and interpreted to better understand the mode of occurrence of the Cu-Au polymetallic deposits and associated structural features. Several analysis techniques, such as reduction to the pole, spectral analysis, low-pass filtering, were applied to process the aeromagnetic data to understand the distribution of magnetic sources. The depth of magnetic sources was estimated by spectral analysis, and the shallower and deeper sources anomalies were analyzed. The Euler deconvolution, total horizontal derivative, tilt angle derivative and thetamap were used to study lineament structures. The new structural scheme was established by comparison of above derivative results and geological data of the Kalatage area. The results show that the study area is affected by sets of NWW-SEE/NW-SE, NNE-SSW/NE-SW and nearly E-W directions faults structures; various probable magmatic rocks may be the results of the ascent and intrusion of magma along these regional fractures in the process of large-scale and deep tectonic-magmatic activities. The polymetallic ore deposits are mainly distributed within the eastern portion of the study area and are confined probably along structure lineament suggesting that it is structurally controlled. Furthermore, the favorable area for mineralization was proposed. These analyses help the recognition of structure features of differing magnetizations, interpretation of tectonic evolution, which could have important reference for further mineral prospecting.

Among the Fischer-Tropsch synthesis (FTS) catalysts, Cobalt catalysts are currently attracting a lot of research interests due to their high activity and high selectivity. But the dispersion and reducibility of cobalt catalysts with moderate interaction between cobalt and support are still a challenge. A novel amino-ended hyperbranched polyamide (AEHPA) was used to modify SBA-15 and then was applied as support for obtaining cobalt catalyst (15Co/SBA-15-N). The catalysts were characterized by XRD, TEM, XPS and H2-TPR techniques. The results showed that AEHPA doped mesoporous SBA-15 caused the generation of N species in the SBA-15 pore channels. The N-Co bonds resulted in the formation of highly-dispersed cobalt nanoparticles with uniform sizes inside the ordered mesopores of support. AEHPA doping was an effective way to modify the surface properties of the SBA-15 for immobilizing cobalt nanoparticles. Compared with the conventional 15Co/SBA-15 catalyst without doping AEHPA, the AEHPA doped 15Co/SBA-15-N catalyst showed improved cobalt dispersion and stabilized cobalt location, which led to much better reaction stability as well as C5+ selectivity.

Woo Ri Ko,Manpreet Boora,Tru Nguyen Dang,Jae Kyeom Kim,Jinlin Zhang,나정효,Zhiyong Fan,Jae Yong Suh,Min Hyung Lee 한국공업화학회 2022 Journal of Industrial and Engineering Chemistry Vol.107 No.-
This paper describes a facile method for the design and fabrication of hierarchical nanopatterns via aluminumanodization with an application for creating plasmonic crystals. Fabrication of highly-orderedanodized aluminum oxide nanopores requires an applied electric potential for anodization, which is typicallyset to match the pitch of nanoindentations on Al. This study reports a new voltage regime for Alanodization conditions where the process yields satellite pores of various shapes, periodicities, and sizesaround the main pores. These new nanopatterned platforms provide an easy route to fabricate hierarchicalmetal nanostructures whose energy dispersions are shaped by the mode superposition of the surfaceplasmon polaritons originating from multiple periodic lattices.
