Effective Solid Electrolyte Interphase Formation on Lithium Metal Anodes by Mechanochemical ModificationThu Oct 12 2023

Magnetic skyrmions are promising information carriers for dense and energy-efficient information storage owing to their small size, low driving-current density, and topological stability.*
Electrical detection of skyrmions is a crucial requirement to drive skyrmion devices toward applications. The use of a magnetic tunnel junction (MTJ) is commonly suggested for this purpose as MTJs are key spintronic devices for large-scale commercialization that can convert magnetic textures into electrical signals. To date, however, it has been challenging to realize skyrmions in MTJs due to incompatibility between standard skyrmion materials and highly efficient MTJ electrodes.*
In the article “Electrical Detection of Magnetic Skyrmions in a Magnetic Tunnel Junction” Yao Guang, Like Zhang, Junwei Zhang, Yadong Wang, Yuelei Zhao, Riccardo Tomasello, Senfu Zhang, Bin He, Jiahui Li, Yizhou Liu, Jiafeng Feng, Hongxiang Wei, Mario Carpentieri, Zhipeng Hou, Junming Liu, Yong Peng, Zhongming Zeng, Giovanni Finocchio, Xixiang Zhang, John Michael David Coey, Xiufeng Han and Guoqiang Yu report a material stack combining magnetic multilayers, which host 100 nm scale skyrmions, with a perpendicularly magnetized MTJ.*
In their article the authors describe how they combined electrical transport measurements with direct imaging of magnetic texture by magnetic force microscopy (MFM).*
The materials stack is designed to imprint the magnetic domain pattern of the multilayer into the MTJ’s free layer via magnetostatic interactions. The evolution of the magnetic domain pattern is revealed by MFM, which shows that skyrmions can be stabilized in the fabricated MTJ with an appropriate magnetic field.*
The realization of electrical reading of skyrmions using an MTJ opens the route to all-electrical skyrmion devices, which is a crucial step for the development of skyrmionics. *
The technique reported by Yao Guang et al. can further advance the simultaneous optimization of the parameters for skyrmion stabilization and MTJ read-out, thus opening a way to realize skyrmion-based devices such as racetrack memory, logic gates, oscillators, detectors,artificial synapses for neuromorphic computing, and reshuffling devices with an efficient CMOS compatible read-out mechanism.*
The magnetic response was studied using NANOSENSORS™ SuperSharpSilicon™ High Resolution Magnetic Force Microscopy AFM Probes ( SSS-MFMR typical force constant 2.8 N/m) in-phase mode and with a lift height of 30 nm. The transport measurements of MTJ were performed in the PPMS or the MFM that is upgraded with electrical measurement equipment.*

Mechanical dynamics of nanoscale interfaces in epoxy nanocomposites over a broad range of temperatures is studied with novel Nanorheology AFM, a.k.a. nanoscale dynamic mechanical analysis (nDMA) and our soft tapping mode AFM probes Multi75Al-G.

"Our nDMA results also show good agreement with those measured by other well-accepted AFM methods at the nanoscale as well as macroDMA over a broad temperature range, which might initiate a new paradigm for characterizing nanoscale dynamic mechanical responses for various structural nanocomposites."

“Heparin is one of the most important naturally derived anticoagulant agents. Its medicinal role originates from the ability to bind coagulant factors and inhibit the blood-clotting cascade… However, in clinical practice, it is of vital importance to reverse its anticoagulant effect to restore the blood-clotting cascade and circumvent side effects. Inspired by protein cages that can encapsulate and protect their cargo from surroundings, we utilize three designed protein copolymers to sequester heparin into inert nanoparticles.”

NANOSENSORS Comparative analysis of frictional behavior and mechanism of molybdenum ditelluride with different structures - news

Comparative analysis of frictional behavior and mechanism of molybdenum ditelluride with different structuresMon Sep 11 2023

Two-dimensional (2D) transition metal dichalcogenides (TMDCs) have layered structures with excellent tribological properties. *

Since the energy difference between hexagonal-molybdenum ditelluride (2H-MoTe2) and distorted octahedral-molybdenum ditelluride (1T’-MoTe2) is very small among the transition metal dichalcogenides (TMDCs), MoTe2 becomes one of the most promising candidates for phase engineering. *

In the article “Comparative analysis of frictional behavior and mechanism of molybdenum ditelluride with different structures”  Lina Zhang, Xinfeng Tan, Jianguo Jiao, Dan Guo and Jianbin Luo report that they found that the friction force and friction coefficient (COF) of 2H-MoTe2 were an order of magnitude smaller than those of 1T’-MoTe2 by the atomic force microscope (AFM) experiments. *

Polyethylene Glycol 20k. Does It Fluoresce?Mon Aug 21 2023

Polyethylene glycol (PEG) is a polyether compound commonly used in biological research and medicine because it is biologically inert. *

This simple polymer exists in variable chain lengths (and molecular weights). As they are devoid of any contiguous π-system, PEGs are expected to lack fluorescence properties. However, recent studies suggested the occurrence of fluorescence properties in non-traditional fluorophores like PEGs. *

In the article “Polyethylene Glycol 20k. Does It Fluoresce?” Bethany F. Laatsch, Michael Brandt, Brianna Finke, Carl J. Fossum, Miles J. Wackett, Harrison R. Lowater, Alex Narkiewicz-Jodko, Christine N. Le, Thao Yang, Elizabeth M. Glogowski, Scott C. Bailey-Hartsel, Sudeep Bhattacharyya and Sanchita Hati report a comprehensive investigation of the molecular basis of the fluorescent properties of PEG 20k molecules using combined experimental and computational methods. Fluorescence measurements of PEG 20k were conducted in aqueous solutions as well as in the presence of metal ions. *
