Rising Temperatures and Surface Mass Loss in Greenland: Implications for Regional Glacier Dynamics and Global Sea Level Rise
Abstract: In Greenland, the ice sheet serves as one of the strongest indicators of global climate change, with consistently rising temperatures driving it toward an even more negative mass balance. Over the last two decades, warmer conditions have exacerbated surface melting, darkened ice, and resulted in feedback stimulating further loss. This study assesses how those temperature trends—particularly during summer peak months—have impacted the stability of Greenland's ice, and then, more importantly, …

Structural, Optical, Surface, and Gas-Sensing Properties of rGO/Sn1–xZnxO₂ Nanocomposites
Abstract: rGO/Sn₁–ₓZnₓO₂ nanocomposites with x = 0.00–0.75 were synthesized by sol–gel auto-combustion followed by wet impregnation with reduced graphene oxide. The adopted synthesis route enabled homogeneous Zn incorporation into the SnO₂ matrix and uniform distribution of rGO, leading to improved structural integrity and interfacial contact between the two components. XRD confirmed a dominant tetragonal cassiterite SnO₂ structure, while FTIR, FESEM, EDS, UV–visible, and BET analyses verified oxide–rGO coupling, Zn-dependent structural modification, …

Evaluation of Surface Replication of Injection Molded Products Using a Diffraction Method
Abstract: ABSTRACT An evaluation method of surface replication for molded parts, which utilizes optical diffraction phenomena, is proposed. In general, the intensity of the diffracted light increases as the replication ratio becomes large, which leads to the increase in directly transmitted light. As a result, the surface in highly replicated region appears to be darker compared with the other region. An inversely proportional relationship between the 0th-order diffraction efficiency and the …
