Understanding structure at the atomic scale is fundamental for understanding the functioning and the development of materials with improved properties. Compared with other probes providing atomic resolution, electrons of...

Artificially tailoring the polarization and phase of light offers new applications in optical communication, optical tweezers, and laser processing. Valley topological physics provides a novel paradigm for controlling el...

Selective etching is an express method to identify the defects of crystal structure of semiconductors. It reveals the dislocations density, type of conductivity, crystal’s orientation, inclusions/precipitates, twins. T...

Isothermal section of the Lu-Ag-Si system at 500ºC was studied by means of X-ray powder diffraction, microstructure and EDX-analyses in the whole concentration range. The existence of earlier reported binary compounds L...

In this paper, we designed a 2×2 optical switch using a two- dimensional photonic crystal (2D PC) based on interference principle. For the first time, an air-hole slab-structure-based photonic switch is proposed. The pr...

In this article, we report modeling, simulation, and analysis of shifting 2D photonic crystal cavity side holes in GaN-AlN-sapphire layered structure. The design was simulated with Lumerical finite-difference time-domain...

Two-dimensional (2D) layered materials without centrosymmetry, such as GaSe, have emerged as promising novel optical materials due to large second-order nonlinear susceptibilities. However, their nonlinear responses are ...

In this study, we evaluated a nanoscale random rubbed structure (nRRS) used as a scattering layer in organic light-emitting diodes (OLEDs) through an innovative manufacturing method. The rubbing technique, which is conve...

Abstract High-dispersed nanoscale Cu precipitates often contribute to extremely high strength due to precipitation hardening, and whereas usually lead to degraded toughness for especially ferritic steels. Hence, it is im...

HoNiSi3 is an intermetallic compound characterized by two successive antiferromagnetic transitions at TN1 = 6.3 K and TN2 = 10.4 K. Here, its zero-field microscopic magnetic structure is inferred from resonant x-ray magn...

In this work, the characteristics of a commercial sample of LaNi5 are compared to those of an experimental one obtained by mechanical alloying followed by low temperature annealing. The nominal composition of the experim...

In linear optical processes, compact and effective wavefront shaping techniques have been developed with the artificially engineered materials and devices in the past decades. Recently, wavefront shaping of light at newl...

Liquid crystalline polyurethanes (LCPUs), having azobenzene mesogenic groups, formed a nematic phase on heating and cooling processes. Liquid crystalline binary mixtures were obtained by mixing LCPUs and strongly polar c...

Abstract This article examines a key element of the power relations underpinning international politics, namely coloniality. It delineates the coloniality of international politics, and elucidates the fundamental aspects...

Simultaneous realization of high quality factor (Q), sensitivity, and figure of merit (FOM) play a pivotal role in building the THz sensor. For such purpose, we propose an all-polymeric Bloch surface wave (BSW) structure...

Light beams carrying multiple orbital angular momentum (OAM) states, which can be realized by the structured media with phase singularities, have attracted great attentions in the fields of high dimensional optical infor...
