Magnetic reversal in perpendicularly magnetized antidot arrays...Mon Dec 16 2019

New post - Magnetic reversal in perpendicularly magnetized antidot arrays with intrinsic and extrinsic defects (https://www.nanoworld.com/…/magnetic-reversal-in-perpendic…/) has been published on NanoWorld Blog.
Defects can significantly affect performance of nanopatterned magnetic devices, therefore their influence on the material properties has to be understood well before the material is used in technological applications. However, this is experimentally challenging due to the inability of the control of defect characteristics in a reproducible manner.*

In “Magnetic reversal in perpendicularly magnetized antidot arrays with intrinsic and extrinsic defects» Michal Krupinski, Pawel Sobieszczyk, Piotr Zieliński and Marta Marszałek construct a micromagnetic model, which accounts for intrinsic and extrinsic defects associated with the polycrystalline nature of the material and with corrugated edges of nanostructures.*

The findings described in their article show that magnetic properties and domain configuration in nanopatterned systems are strongly determined by the defects, the heterogeneity of the nanostructure sizes and edge corrugations, and that such imperfections play a key role in the processes of magnetic reversal.*

The magnetic imaging described in the article cited above was performed using NanoWorld MFMR AFM probes for magnetic force microscopy (MFMR). https://www.nanoworld.com/pointprobe-magnetic-force-microsc…

Single layer graphene induces load-bearing molecular layering at...Wed Dec 11 2019

Published new post (Single layer graphene induces load-bearing molecular layering at the hexadecane-steel interface) on NANOSENSORS Blog

Carbon-based layers play an important role in boundary lubrication, from graphite as commercial solid lubricant in a spray can over diamond-like carbon coatings in automotive industries all the way to graphitic layers found in metal-metal hip implants. With increasing availability of graphene, the two-dimensional building block of graphite, its possible role in lubrication is being explored. *

After the discovery of friction and wear reduction on steel surfaces by graphene in a variety of environments, graphene is now emerging as new lubricant. Polymer composites with graphene exhibit improved tribological properties due to wear reduction by efficient transfer layers. The composite approach has been successfully extended to multilayers of polymer and graphene. The use of graphene as additive in formulated lubricant oils is also promising after functionalization to improve solubility. *

In their letter “Single layer graphene induces load-bearing molecular layering at the hexadecane-steel interface” G. Krämer, C. Kim, K-S. Kim and R. Bennewitz report experimental results for fundamental lubrication properties of the interface between a hexadecane model lubricant and a steel surface modified by a single layer graphene. Using high-resolution force microscopy, they quantify that the reduction of friction on graphene is connected to an ordered layer of adsorbed hexadecane molecules and that the graphene induces an ordering in molecular layers in the confined liquid above graphene patches. *

A single layer of graphene on steel surfaces causes a change in the near-surface structure of the model lubricant hexadecane. Hexadecane adsorbs in an ordered layer aligned straight molecules, and this layer is stable under scanning in contact with the tip of an atomic force microscope, while no such layer is observed on the steel substrate. Graphene and hexadecane layer reduce friction at the nanoscale by a factor of three compared to the bare steel in hexadecane. *

All AFM measurements described in this letter were performed using a NANOSENSORS™ PointProbe® Plus PPP-CONTR AFM probe at room temperature with a home-built fluid cell where the cantilever was fully immersed in hexadecane.* https://www.nanosensors.com/pointprobe-plus-contact-mode-af…

NanoWorld Flexible Robust and High‐Density FeRAM from Array of Organic Ferroelectric Nano‐Lamellae by Self‐Assembly - news

Flexible Robust and High‐Density FeRAM from Array of Organic Ferroelectric Nano‐Lamellae by Self‐AssemblyTue Dec 10 2019

New post - Flexible Robust and High‐Density FeRAM from Array of Organic Ferroelectric Nano‐Lamellae by Self‐Assembly (https://www.nanoworld.com/…/flexible-robust-and-high%e2%80…/) has been published on NanoWorld® Blog. Ferroelectric memories are endowed with high data storage density by nanostructure designing, while the robustness is also impaired. For organic ferroelectrics favored by flexible memories, low Curie transition temperature limits their thermal stability.* In their article “Flexible Robust and High‐Density FeRAM from Array of Organic Ferroelectric Nano‐Lamellae by Self‐Assembly “ Mengfan Guo, Jianyong Jiang, Jianfeng Qian, Chen Liu, Jing Ma, Ce‐Wen Nan and Yang Shen demonstrate that a ferroelectric random access memory ( FeRAM ) with high thermal stability and data storage density of ≈60 GB inch−2 could be achieved from an array of edge‐on nano‐lamellae by low‐temperature self‐assembly of P(VDF‐TrFE).* The self‐assembled P(VDF‐TrFE) described in the article exhibits high storage density of 60 GB inch−2 as a prototype of flexible FeRAM. The authors experimentally determine the self‐assembled FeRAM stored data more robustly, with temperature endurance enhanced over 10 °C and reliable thermal cycling ability. The article shows a novel path to address the thermal stability issues in organic FeRAMs and presents a detailed analysis about the origin of enhanced performance in aligned P(VDF‐TrFE). * NanoWorld® Arrow-CONTPt AFM probes with a conducting Pt/Ir coating were used for the Piezoresponse Force Microscopy ( PFM ) measurements described in this article.https://www.nanoworld.com/contact-mode-platinum-coated-afm-… Please have a look at the NanoWorld® blog for the full citation and a direct link to the full article. #ferroelectrics #polymers #materialsresearch #AFMprobes

We are often asked whether our ElectriCont-G probes are suitable for Conductive AFMMon Dec 02 2019

We are often asked whether our ElectriCont-G probes are suitable for Conductive AFM. These probes are not designed for C-AFM, although many of our customers use them as a cost-effective alternative to the much more durable conductive diamond coated probes such as the AIO-DD. The two current images show that C-AFM measurements are possible but hard to achieve. Fine-tuning of scan parameters is required to make the platinum coating on the apex last.

NANOSENSORS cdS quantum dots-based immunoassay combined with particle imprinted polymer technology and laser ablation icp-MS as a versatile tool for protein detection - news

cdS quantum dots-based immunoassay combined with particle imprinted polymer technology and laser ablation icp-MS as a versatile tool for protein detectionMon Nov 25 2019

cdS quantum dots-based immunoassay combined with particle imprinted polymer technology and laser ablation icp-MS as a versatile tool for protein detection on NANOSENSORS Blog The molecularly imprinted polymer ( MIP ) technology is currently experiencing a rapid development due to the limitations of natural recognition elements such antibodies or aptamers.* However, neither MIP strategies are limitless. Therefore, the combination of these powerful tools in a specific immunoassay may bring highly selective approach.* In their article “cdS quantum dots-based immunoassay combined with particle imprinted polymer technology and laser ablation icp-MS as a versatile tool for protein detection” Tereza Vaneckova, Jaroslava Bezdekova, Michaela Tvrdonova, Marcela Vlcnovska, Veronika Novotna, Jan Neuman, Aneta Stossova, Viktor Kanicky, Vojtech Adam, Marketa Vaculovicova and Tomas Vaculovic introduce a MIP-based pseudo-immunoassay using NP-labelled antibody recognition and couple it with the sensitive detection technique laser ablation inductively coupled plasma mass spectrometry ( LA-ICP-MS ).* Two approaches of specific recognition were tested. The first one was based on the immunolabelling of the analyte captured by the MIP layer. The second approach involved immunolabelling of the analyte as a first step and the resulting QD-AB-AG complex was captured by MIP and further analyzed. The double-selective approach comprising of the specific immunolabelling reaction combined with isolation by MIP together with the LA-ICP-MS detection represents a viable approach of the IgG detection from a complex sample (LOD 4.2 μg and 1.6 μg, respectively) available for many exciting applications. Considering the overall time of the LA-ICP-MS analysis not exceeding 23 s (scan speed of 2000 μm/s), LA-ICP-MS is a promising technology to be used in future in conjunction with MIP technology.* The sample surface was analyzed using SEM with integrated AFM. Correlative Probe and Electron Microscopy (CPEM)48 was used for the surface analysis allowing simultaneous acquisition of SEM and AFM images at the same place in the same coordinate system. The SEM contrast is sensitive to the sample composition, while the AFM provides real surface topography. The accelerating voltage of 5 kV, beam current of 13 pA and SE detector was used for SEM imaging.* NANOSENSORS self-sensing self-actuating Akiyama probes in tapping mode were used for the AFM measurement. https://www.akiyamaprobe.com/ Please have a look at the NANOSENSORS blog for the full citation and a direct link to the full article.#immunochemistry #AtomicForceMicroscopy #AFM

NanoWorld Cellulose carbamate derived cellulose thin films: preparation, characterization and blending with cellulose xanthate - news

Cellulose carbamate derived cellulose thin films: preparation, characterization and blending with cellulose xanthateMon Nov 18 2019

New post - Cellulose carbamate derived cellulose thin films: preparation, characterization and blending with cellulose xanthate (https://www.nanoworld.com/…/cellulose-carbamate-derived-ce…/) has been published on NanoWorld Blog. Despite being rather old, the Viscose process still is the most important and frequently used technology for the production of regenerated wood based fibers with annual production volumes exceeding 3.5 million tons, mainly for the textile industry.* However, there are several environmental drawbacks of this technology. For instance, the necessity to use CS2 to form the cellulose precursor material (cellulose xanthate, CX), as well as the development of volatile sulfur containing compounds (e.g. H2S, COS) during the regeneration procedure requires complex recovery technologies, which manifest into higher prices of the final fiber products.* Another technology that has raised attention in recent years is the Carbacell process. The Carbacell process relies on cellulose carbamate (CC), which is easily obtained by reacting cellulose with urea. CC is soluble in cold alkali and can be subjected to wet spinning processes similar to those in viscose plants.* In their article: “Cellulose carbamate derived cellulose thin films: preparation, characterization and blending with cellulose xanthate” Michael Weißl, Mathias Andreas Hobisch, Leena Sisko Johansson, Kay Hettrich, Eero Kontturi, Bert Volkert and Stefan Spirk introduce a new system for manufacturing cellulose thin films based on ecofriendly CC. * Since CC is water soluble, the use of organic solvents is omitted compared to the other often employed cellulose derivative, TMSC. In addition, CC can be synthesized in large scale via environmentally friendly procedures. The regeneration process itself does not require any additional treatment but is induced by increasing the NaOH concentration during the spin-coating via evaporation of the water, as confirmed by IR and XPS spectroscopy.* Atomic Force Microscopy in tapping mode using a NanoWorld Arrow-NCR AFM probe was employed to gain further information about the surface morphology and structure of the CC films. https://www.nanoworld.com/tapping-mode-reflex-coated-afm-ti… Please have a look at the NanoWorld blog for the full citation and for a direct link to the full scientific article. #Cellulose #ThinFilm #AFM

BudgetSensors Tip wear and tip breakage in high-speed atomic force microscopes - news

Tip wear and tip breakage in high-speed atomic force microscopesTue Nov 05 2019

High speed scanning (HSS) AFM tests with our ContDLC AFM probes at velocities up to 1mm/s demonstrate the high durability of our diamond-like carbon coated tips. Scanning hard surfaces with sharp, steep edges at ultrahigh scan rates increases the danger of sudden apex breakage due to sudden high lateral forces. So, please do not HSS our TipCheck! :) Learn more in this in-depth study published in the Ultramicroscopy journal. #AFMProbes #AtomicForceMicroscopy #HighSpeedScanning
