| 1 | Optical spin-symmetry breaking for high-efficiency directional helicity-multiplexed metaholograms显示文摘Helicity-multiplexed metasurfaces based on symmetric spin–orbit interactions (SOIs) have practical limits because they cannot provide central-symmetric holographic imaging. Asymmetric SOIs can effectively address such limitations, with several exciting applications in various fields ranging from asymmetric data inscription in communications to dual side displays in smart mobile devices. Low-loss dielectric materials provide an excellent platform for realizing such exotic phenomena efficiently. In this paper, we demonstrate an asymmetric SOI-dependent transmission-type metasurface in the visible domain using hydrogenated amorphous silicon (a-Si:H) nanoresonators. The proposed design approach is equipped with an additional degree of freedom in designing bi-directional helicity-multiplexed metasurfaces by breaking the conventional limit imposed by the symmetric SOI in half employment of metasurfaces for one circular handedness. Two on-axis, distinct wavefronts are produced with high transmission efficiencies, demonstrating the concept of asymmetric wavefront generation in two antiparallel directions. Additionally, the CMOS compatibility of a-Si:H makes it a cost-effective alternative to gallium nitride (GaN) and titanium dioxide (TiO2) for visible light. The cost-effective fabrication and simplicity of the proposed design technique provide an excellent candidate for high-efficiency, multifunctional, and chip-integrated demonstration of various phenomena. | Muhammad Ashar Naveed Muhammad Afnan Ansari Inki Kim Trevon Badloe Joohoon Kim Dong Kyo Oh Kashif Riaz Tauseef Tauqeer Usman Younis Murtaza Saleem Muhammad Sabieh Anwar Muhammad Zubair Muhammad Qasim Mehmood Junsuk Rho | 2021 | Microsystems & Nanoengineering2021，7，2： | 3 |

| 11 | Articulating CO_(2)emissions limiting roles of nuclear energy and ICT under the EKC hypothesis:An application of non-parametric MMQR approach显示文摘Limiting toxic elements from being exposed to the world’s atmosphere has been the biggest challenge among environmental researchers and stakeholders.Climate change conferences have been counselling the global economies to take serious steps toward profound decarbonization to keep the universal temperature below 1.5C.In this context,the direction of environmental research has changed,and researchers are more focused on tracing how to limit pollution and keep it below the threshold level.In this milieu,nuclear energy can make a big difference along with other alternatives to fossil energy.Therefore,we extend the extant literature by exploring the dynamic effects of atomic energy and ICT on carbon emissions(CO_(2))for top nuclear energy countries using data from 1990 to 2017.To obtain robust findings,we deploy a novel non-parametric econometric approach(i.e.,method of moments quantile regression).The results suggest that nuclear energy is a sustainable alternative to historical fossil fuel as it curbs CO_(2)emissions in the lower,middle,and upper quantiles.Furthermore,our findings corroborate that ICT penetration through the internet,mobile and telephone plays a vital role in improving environmental quality.Moreover,we unveil that linear economic growth jeopardizes the environment by unleashing harmful gases.The findings also support the existence of the Environmental Kuznets Curve(EKC)hypothesis by confirming the negative association between the polynomial economic growth(squared-GDP)and CO_(2)emissions among the designated nations.Also,the Granger causality test reaffirms the causal nexus among selected series that runs from nuclear energy and technological innovation to CO_(2)emissions,indicating that any policy shock in both series leads to environmental degradation.We,therefore,advocate that the designated territories keep enriching their energy baskets with nuclear energy and boost ICT penetration to achieve a 100%decoupling of economic growth from pollution. | Atif Jahanger Umer Zaman Mohammad Razib Hossain Ashar Awan | 2023 | Geoscience Frontiers2023，14，5： | 1 |
