𝐒𝐏𝐔𝐓𝐓𝐄𝐑 𝐀𝐍𝐃 𝐂𝐀𝐑𝐁𝐎𝐍 𝐂𝐎𝐀𝐓𝐄𝐑 𝐒𝐍𝐂𝐂-𝟏𝟖𝟎𝐑 Sputter coating of SEM samples is the process of coating ultrathin electrically conductive thin films of conductive materials like Gold, Gold/ Palladium, Platinum, Silver on non-conductive (insulating) specimens. Electrically conductive specimen interact better with the electron beam of the SEM which gives clear image. However non-conductive specimen build up electro static charge from the electron beam of the SEM and therefore interferes with the signal used to create the SEM image. Sputter coating thin films of conductive materials on non-conductive specimens prevents electro-static charge build up over such specimen. It also increases the amount of secondary electrons generated from the specimen surface detected by the SEM which increases the signal to noise ratio resulting in better imaging. Sputtered films for SEM typically range in2-20nm thickness. Carbon Coating is used in sample preparation for subsequent observation under scanning electron microscope (SEM), Transmission electron microscope (TEM), and X-Ray analysis (EDX). This is because carbon has a low atomic number and the peak of the X-ray graph of carbon doesn’t interfere with other peaks of other elements. Carbon film with evaporated carbon fiber or carbon rod is deposited on the sample. Carbon evaporates from the fiber or rod as a result of electric current passing through them and deposited on the sample. The thickness of the deposited film depends on the thickness of the thread used and the time it passes through it. Suitable thicknesses for sample preparation for electron microscopy or X-ray analysis are between 5 and 20 nm. 🌟 𝐖𝐚𝐭𝐜𝐡 𝐨𝐮𝐫 𝐯𝐢𝐝𝐞𝐨- https://lnkd.in/eY7UZW55 🌟𝗕𝗼𝗼𝗸 𝘆𝗼𝘂𝗿 𝗳𝗿𝗲𝗲 𝗱𝗲𝗺𝗼 𝗻𝗼𝘄!

Piezoelectric-induced shocks transform indium selenide from crystalline to glassy phase. Using aberration-corrected electron microscopy, an India-US team of materials scientists has discovered that a 2D ferroelectric material, indium selenide, can 'shock' itself to transform from a crystalline to glassy phase using very low power. Such a phase change lies at the heart of memory storage in CDs and computer RAMs, and consumes a billion times less power than the laser-triggered melt-quench process used to convert crystal to glass when recording data.

Join our Lead Scientist Sonia Castellanos at the #SPIElitho conference for a discussion on EUV metal oxide resist thermal chemistry and patterning progress.   26 February 2024 ∙ 2:50 PM - 3:10 PM PST | Convention Center, Grand Ballroom 220C   Sonia will discuss the thermal amplification processes via both patterning and chemical data as a function of underlayer, resist, and bake condition. This will assist lithographers in optimizing and comparing different resists, stacks, and bake temperatures. The translation of MOR formulation and process advances to hNA patterning performance is demonstrated using 0.5-NA imaging data collected on the Berkely MET-5, in which we explore pitches ≤ 20 nm.   #SPIE #lithography

🚨This recent publication from Dr. Hooman Tafreshi's group at North Carolina State University introduces a new computational method that advances the state-of-the-art in modeling electrospinning processes. The group developed their computational model based on various configurations of needles (emitters) and collectors in a Fluidnatek LE-50 G1 Electrospinner to help predict how electrostatic fields impact the diameter and velocity of fibers produced in electrospinning processes. 📖Read the paper: https://lnkd.in/e8BQySga 💡Learn about the LE-50 Professional-grade Electrospinning system: https://lnkd.in/edZBHgsH #Electrospinning #Nanofibers #Nonwovens #Polymers #Nanomaterials #NanoscienceInstruments Fluidnatek & Spinbox by Bioinicia

How Does a Sonifier Work? Sonifiers, or ultrasonic homogenizers, play a vital role in breaking down particles, disrupting cells, and mixing samples through the use of high-frequency sound waves. By applying ultrasonic energy, sonifiers create microscopic bubbles in liquids, which then collapse, generating intense shear forces. This process helps in cell lysis, nanoparticle dispersion, and even emulsification of liquids. Whether in research labs or industrial applications, sonifiers are essential for precision mixing and sample preparation. #Sonication #Ultrasonics #LabTech #ResearchInnovation#Branson Sonifier 250

Groundbreaking method merging multiscale X-ray diffraction and high-res electron microscopy, scientists at Brookhaven and Argonne helped pinpoint the root cause of performance fade in nickel-rich cathodes for lithium-ion batteries. The team have uncovered the mystery behind the performance decline in nickel-rich cathodes for lithium-ion batteries. Their innovative analysis method played a crucial role in this breakthrough. The quest for enhancing battery materials to boost driving range and reduce costs continues to evolve, with a focus on improving the cathode. Various cathode materials show promise in achieving higher energy storage, but the decline in capacity during charge-discharge cycles has remained a challenge. Tongchao Liu, assistant chemist, highlights the potential of their method in understanding failure mechanisms in various battery types beyond current lithium-ion technology.
