In the seemingly small world of molecular nanostructures, research led by Professor Adam Mechler is having a big impact. Molecular nanostructures are molecules that have been organised and arranged at the extremely small nanoscale to have unique chemical properties and functions. They are used for a wide range of industry applications. Professor Mechler creates molecular nanostructures by designing molecules that stick together like a self-assembling molecular LEGO system. "We have discovered that by using helix-shaped units as molecular bricks we can connect them end-to-end to create nanorods – tiny rods around one thousand times thinner than a human hair, with specific chemical functions,” Professor Mechler explains. “Our findings offer the potential to revolutionise the design of surface coatings, particularly for the aerospace industry.” “Another application is the development of radiation-reflecting, antistatic, self-healing layers designed to safeguard satellites from the harsh and destructive conditions of outer space."

Excited to share our latest research publication on helical undulators made from magnetized ring sectors! In this work, we demonstrate how arrays of permanent magnet ring segments can create helical magnetic fields similar to solid helical undulators, but with easier manufacturing and assembly. Our prototype Halbach-type undulator with a 2 cm period achieved impressive on-axis fields of ~0.6 T, with potential to reach over 1 T by optimizing the design. These compact, high-field undulators could significantly boost the efficiency of Free Electron Lasers across various frequency ranges. We're looking forward to seeing how this technology may advance coherent radiation sources and particle accelerators. A special shout-out to Ahiya Steiner, who served as a research assistant on this project during his third year of undergraduate studies. Ahiya implemented the system and conducted all the measurements, making invaluable contributions to this research. Great job, Ahiya!

Exciting breakthrough from Indian Institute of Technology, Madras' Centre for 2D Materials Research and Innovations (C2DMRI)! Researchers have achieved intense dipolar emission at room temperature using a van der Waals heterostructure of PbI2 and bilayer WS2. This discovery marks the first observation of a large interlayer excitonic emission at room temperature, tunable across a broad spectral range (1.70 to 1.45 eV) by varying WS2 thickness. Led by Prof. Abhishek Misra, Centre for 2D Materials Research and Innovations, Dept of Physics, #IITMadras, this work opens new avenues for developing excitonic-based optoelectronic devices for free space communications and exploring advanced Bosonic physics, including Bose-Einstein condensation and dissipation-less electrical transport at elevated temperatures.

🌟 Breakthrough in Nonlinear Optical Effects in Antiferromagnetic Materials A recent study has unveiled a nonlinear "skin effect" in antiferromagnetic materials, where nonlinear optical phenomena, such as the bulk photovoltaic effect, are confined to the material's surface regions. Highlights of the Research: Key Findings: Surface-Dominant Nonlinear Responses: The nonlinear effects are concentrated at the top and bottom surfaces, leaving the interior largely unaffected. Mechanism: Global inversion symmetry: Broken across the material. Local inversion symmetry: Remains intact in the interior, driving surface-specific responses. Material Studied: The 2D antiferromagnetic material CrI₃ served as the model system. Methods: First-Principles Calculations: To predict optical behavior. Second-Harmonic Generation (SHG): Experimentally validated the findings. Implications: This discovery could revolutionize optoelectronics, enabling: Advanced high-performance devices with surface-targeted functionalities. Better designs for photovoltaic systems, leveraging surface properties for efficiency. Insights into fundamental physics and material behaviors under nonlinear optical conditions. 📘 Read the full article: Phys.org 💡 What are your thoughts on applying this unique effect to optoelectronic innovations? #Physics #MaterialsScience #AntiferromagneticMaterials #NonlinearOptics #CrI3 #Optoelectronics #Innovation
