The behavior of S and Cs during the alternate adsorption of each adsorbate on the Ni(100) surface is studied at room and elevated temperatures by means of low energy electron diffraction (LEED), Auger electron spectroscopy (AES), thermal desorption spectroscopy (TDS) and work function (WF) measurements. For Cs deposition on the S-covered Ni(100) surface, the presence of sulfur increases the binding energy and the maximum amount of adsorbed cesium as it happens with other alkalis too. The first Cs overlayer is disordered, while the second strongly interacts with S in a tendency toward a CsxSy surface compound formation. This strong interaction causes the gradual demetallization of the Cs overlayer with increasing S coverage in the underlayer. When the CsxSy stoicheometry is complete, however, subsequent Cs deposition forms an independent rather metallic overlayer. When the sulfur covered surface, S(0.5ML)/Ni(100) is preheated to 1100 K, the S-Ni bond strengthens and S-Cs interaction correspondingly weaken to a degree that the S underlayer retains a periodic structure on the Ni substrate. This behavior indicates that the preheated S/Ni(100) surface is passivated. Differently, when S is adsorbed on the Cs-covered Ni(100) surface at room temperature, sulfur adatoms diffuse underneath the Cs overlayer to interact with the nickel substrate in the same manner as on clean surface. During that process the sticking coefficient of sulfur remains constant regardless the amount of predeposited cesium. The presence of Cs, however, increases the amount of S that can be deposited on the Ni substrate, probably in favor of the CsxSy surface compound formation, which demetallizes the surface independently of the sequence of adsorption.

This research aims to explore the implications of fashion content dissemination on TikTok as a digital cultural phenomenon that influences lifestyle standards and fashion trends among Gen Z in Denpasar City. The primary focus of this study is to analyze the impact of influencer @nazwaadinda's account on Gen Z's fashion preferences, along with the positive and negative effects arising from this phenomenon. Within the context of digital culture, TikTok has become a key platform for Gen Z to seek lifestyle inspiration, particularly through interactive and creative visual content. The Uses and Gratification Theory is employed to understand the motivations and satisfaction of Gen Z in consuming fashion content, including their reasons for connecting with influencers like @nazwaadinda. The findings reveal that content shared by Nazwaadinda not only shapes clothing choices but also influences shopping habits and trend-oriented mindsets. While it offers positive impacts such as enhanced creativity and increased fashion awareness, this phenomenon also brings about social pressures to adhere to specific standards and anxiety related to ideal body image. As part of digital culture, TikTok creates a space where fashion trends evolve dynamically, reflecting the collective identity of Gen Z, particularly in Denpasar. This phenomenon highlights how social media acts as a cultural agent that shapes the perceptions and behaviors of young generations in the digital era. Keywords: Dissemination of Fashion Content, TikTok, Digital Cultural Phenomenon, Gen Z, Denpasar City
Abstract To address challenges such as signal interference and crosstalk, the development of novel materials with the ability to absorb electromagnetic waves (EMA) is imperative. In this study, we achieved outstanding EMA properties, including an RLmin of 75 dB at 10.2 GHz and a 2.5 mm thickness, accompanied by an exceptionally wide effective bandwidth of 8.8 GHz. We accomplished this feat by employing advanced techniques in high-entropy and phase regulation engineering within the framework of CsMBr3 perovskite. Our approach involved the strategic introduction of diverse magnetic elements, such as Fe, Co, Ni, and Mn, into the CsPbBr3 matrix. The presence of high entropy was validated through meticulous analysis using Rietveld and GIWAXS patterns. We meticulously synthesized high-entropy Cs(Pb, Fe, Co, Ni, Mn)Br3 square nanoparticles within the size range of 30–50 nm, ensuring their uniform dispersion. As we progressively augmented the high-entropy content, we observed notable lattice distortion within PbBr6, ultimately leading to a phase transition characterized by orthorhombic and tetrahedral configurations. Our comprehensive measurements consistently demonstrated improvements in key parameters, including magnetic permeability, dielectric constant, polarization, and attenuation loss, as the high-entropy ratio reached 3 within the crystal. The driving force behind these enhanced EMA characteristics can be attributed to the synergistic effects arising from high-entropy alloying and the introduction of disordered crystal phases. This synergy significantly heightened conductivity, amplified magnetic losses, and fostered multiple scattering effects, collectively contributing to the observed advancements in EMA performance.
