Hello ,As you can see in the plot bellow I have made several TDR of different materials on one plot. I need to deside which is the best material to use. Also I know that based on (S21_10inch-S21_5inch)/L I find the loss per inch. Two questions: 1.after I find the loss per inch how do I find the... Read more

Porous materials are the preferred choice for high-power laser coating applications. Scientists in China developed a method for preparing porous SiO2 materials by combining electron beam co-evaporation with selective chemical etching.

A recent major investment in Syracuse University research infrastructure has resulted in the installation of a Zeiss Sigma 360 field emission scanning electron microscope in the University’s Materials Research Core (MRC) facility. The instrument has introduced dramatic new imaging capabilities to researchers at the University and at partner institutions in the region. The new instrument demonstr.…

Nature Communications, Published online: 02 June 2026; doi:10.1038/s41467-026-73823-5 Using newly developed electron imaging and applied to epitaxial BiFeO3 thin films, the authors uncover a depth evolution of polar textures: surface stripe domains transform into subsurface flux-closure vortices, which bifurcate into three-fold vertices near the bottom electrode.

IntroductionThis study investigates the influence of electrospark alloying (ESA) parameters on the morphological characteristics, microhardness, and abrasive wear resistance of coatings deposited on 1045 steel using VK15 alloy and R6M5 steel electrodes.MethodsCoatings were produced at specific processing times of 1 and 2 min/cm2. Their performance was evaluated through microhardness measurements …

Insider Brief PRESS RELEASE — A new technology created by Heriot-Watt University is poised to upend one of the most stubborn bottlenecks in modern manufacturing. FreeForm Photonics is set to commercialise a laser-based process that builds alignment directly into optical glass components, removing the painstaking manual calibration that currently accounts for more than half of […]

Nature Communications, Published online: 31 May 2026; doi:10.1038/s41467-026-73939-8 Understanding the structural origins of stability in disordered solids is essential for predicting mechanical failure and manipulating their properties, yet the inherent disorder complicates this analysis. This study identifies stabilizing bonds as critical structural features that govern stability across a spect…

Scientists at the University of California San Diego have created a new optical device that can reveal hidden images and change colors when exposed to different levels of humidity. The technology could one day be used in anti-counterfeiting labels, secure data storage systems, smart displays, and environmental sensors. The small device, about the size of […] The post Scientists create humidity-ac…

Mid-infrared (MIR) spectral region represents a vital part of the electromagnetic spectrum, offering applications in spectroscopy, biomedicine, and remote sensing. However, there are no direct broadband MIR laser sources. Nonlinear frequency conversion techniques using second-order nonlinear materials, such as optical parametric oscillator (OPO) and intra-pulse difference frequency generator (IDF…

The operating lifetime of Ni-YSZ fuel electrodes used in solid oxide electrolysis cells and fuel cells (SOECs and SOFCs) is limited by Ni redistribution, one of the primary degradation mechanisms that must be overcome to extend the longevity and maximize the performance of SOECs and SOFCs. To achieve this, 3D microstructural data is needed to relate both initial performance and performance loss o…

Nature Chemistry, Published online: 28 May 2026; doi:10.1038/s41557-026-02168-9 Organic ferroelectrics typically exhibit modest polarization and high coercive fields, which limit their performance. Now a donor–acceptor cocrystal in which V-shaped donor molecules assemble into a gear-like packing motif has been developed; this architecture enables low-barrier in-plane molecular rotations that enha…

Low-dimensional materials and transition metal surfaces/interfaces provide complementary platforms for understanding how dimensionality, symmetry, spin–orbit coupling (SOC), and interfacial charge transfer/hybridization jointly control electronic structure, emergent magnetism, and surface reactivity. Using first-principles modeling with experimental comparisons, this work aims to establish interf…
