Researchers at the National Institute of Standards and Technology (NIST) and The National Institutes of Health have unveiled a novel fabrication method for #ShapeShifting probes called geometrically encoded #magnetic #sensors (GEMS). The scientists developed a precision master mold to construct the probes faster and more cheaply outside of a #nanofabrication facility, eliminating the need for specialized instruments. Microscopic magnetic probes containing #IronOxide #nanoparticles that change shape in response to their environment may enhance magnetic resonance #imaging (#MRI) technology. https://lnkd.in/eu9F78ys (Work funded by the National Institute of Standards and Technology (NIST), the National Science Foundation (NSF), and the The National Institutes of Health)

Researchers from the UAB and the ICN2 have developed a methodology that makes it possible for the first time to observe under the microscope, in real time, what happens when glass is heated and changes to a supercooled liquid phase, known as the "glass transition". The research, published in Nature Physics, is of great importance for the cryopreservation of proteins, cells and living tissues, for the manufacture of drugs and electronic devices, and for tissue engineering, where this glass-to-liquid transition plays a key role.

🔬 Unlocking the Future with Atomic Precision: Making of Atomically Precise Pores Working with Matthew Boebinger, Raymond Unocic, Yury Gogotsi and collborators at ORNL and Penn State we report the fabrication of atomically precise pores in MXenes using feedback controlled electron beam fabrication. But why is this precision so crucial? 1. Improved Sensing Capabilities: Precision at the atomic level enhances the sensitivity and selectivity of sensors. This is vital for detecting minute quantities of chemical or biological substances, leading to advancements in environmental monitoring, medical diagnostics, and security systems. 2. Molecular Electronics: By controlling the flow of individual molecules through these tiny pores, we can pave the way for the next generation of molecular electronics. This could lead to faster, smaller, and more efficient electronic devices, transforming the tech landscape. 3. Precision medicine: By creating atomically precise pores, we hope to significantly improve the sleectivity for protein sequencing and hence open pathway for precision medicine 4. Material Science Innovation: The techniques developed for atomic-scale fabrication open new avenues in material science. This includes cundertsanding strucutre property relationships and material evolution pathways. The journey towards atomically precise fabrication is a testament to human ingenuity and the relentless pursuit of perfection. It’s not just about making things smaller; it's about redefining what's possible - and having fun while doing it! 🌟 #Nanotechnology #MaterialScience #Innovation #TechAdvancements #Sustainability #FutureOfScience #AtomicPrecision https://lnkd.in/eDbKsDDe

How precisely can the microstructure of nanowires be engineered? Gaurav Modi, Ritesh Agarwal, and their colleagues at the University of Pennsylvania published the results of Ge-Sb-Te nanowire self-assembly experiments using their Hummingbird Scientific in-situ MEMS heating + biasing TEM holder (https://lnkd.in/gYuZD3d). The team demonstrated precise tunability of nanowire synthesis by tuning precursor flux ratios during vapor−liquid−solid growth, deterministically varying the nanowire growth direction, facets, and periodicity of the cation ordering. The researchers fabricated phase-change memory devices showing vastly different amorphization current densities based on the growth direction. In-situ monitoring of the nanowire structure evolution during heating revealed a transition from the cation-ordered to disordered phase between 180-190 °C. These insights into thermodynamic driving forces of nanowire microstructure, combined with the ability to precisely tailor nanowire superstructures will open up new opportunities to modulate fundamental properties like electronic and thermal transport for applications like ultra-low power electronics and thermoelectrics.

This outstanding paper (https://lnkd.in/e5VuJr3N), recently out in Advanced Science, discloses exact analytical solutions for cylindrical magnets systems with programmable magnetization! Such solutions allow for striking speedup gains compared to numerical simulations (of up to 10^6, already for simple testcases), and advance a gamut of applications, including magnetic actuation/localization, computation and magnetic tools, e.g., for biomedical applications. They also foster the development of magnetic soft materials and robots. This study, led by Edoardo Sinibaldi (Istituto Italiano di Tecnologia), may reshape magnetic modeling/computation, and the design of programmable magnetic systems! #magnets #modeling #magneticactuation #magneticlocalization #magneticmaterial #magneticrobot #magnetictool #bioengineering #biorobotics #exactsolution #analyticalsolution #programmablemagnetization #innovation #engineering #physics #stem #cuttingedgeresearch #scientificdiscoveries #researchbreakthrough #scientificadvancement

How can we record the motions of atoms and molecules, which often occur within trillionths of a second? While I was at Berkeley Lab, I had the pleasure of working with daniele Filippetto and the High Repetition-rate Electron Scattering (HiRES) team to develop a next-generation "ultrafast electron scattering" machine. This tool can capture these motions with greater clarity in a broad range of substances, including nanomaterials and gases, which will provide valuable insights into physical and chemical processes on their native length and time scales. We just published an article about this new tool as part of an invited collection, and the work was selected by the editors for a science highlight!
