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. *

Measuring the Diameter of Single-Wall Carbon Nanotubes Using AFMTue Aug 08 2023
AFM height measurements can produce inaccurate results even with a properly calibrated scanner. Our 4-cantilever AFM probes HQ:XSC11/Al BS support this research on how to measure the diameter of single-wall carbon nanotubes (SWCNT) accurately by taking account of compression effects and roughness.
Electrical and magnetic anisotropies in van der Waals multiferroic CuCrP2S6Mon Aug 07 2023
In the field of modern information storage, the physical properties could act as the storage “medium”, such as electric polarization (dipole orientation) of ferroelectric materials, or spin polarization (magnetic vector) of magnetic materials. *
Multiferroic materials have great potential in non-volatile devices for low-power and ultra-high density information storage, owing to their unique characteristic of coexisting ferroelectric and ferromagnetic orders.

Phosphorylation of phase-separated p62 bodies by ULK1 activates a redox-independent stress response
Liquid–liquid phase-separated biomolecular condensates, liquid droplets play an important role in many biological processes, such as gene expression, protein translation, stress response, and protein degradation, by incorporating a variety of RNA and client proteins into their interior depending on the intracellular context. * Autophagy is involved in the degradation of several cytoplasmic liquid droplets, including […]

Low resistance electrical contacts to few-layered MoS2 by local pressurizationTue Aug 01 2023
This work investigates improving the performance of MoS2 electronic and optoelectronic devices by fabricating low-resistance contacts via local pressurization. MoS2 is found to undergo a reversible semiconductor-to-metal transition under pressures >15GPa with significant reduction in contact resistance and increase in field-effect mobility. Our diamond-coated All-In-One-DD AFM tips are used for scanning the sample topography, apply the desired load in the area of interest and extract current-voltage (I-V) curves.
Local pressurization of metal-MoS2 contacts opens possibilities for pressure-controlled contact electromechanical MoS2 devices.
Strong, tough, rapid-recovery, and fatigue-resistant hydrogels made of picot peptide fibresThu Jul 27 2023
Hydrogels are promising soft materials as tissue engineering scaffolds, stretchable sensors, and soft robotics. *
Yet, it remains challenging to develop synthetic hydrogels with mechanical stability and durability similar to those of the connective tissues. Many of the necessary mechanical properties, such as high strength, high toughness, rapid recovery, and high fatigue resistance, generally cannot be established together using conventional polymer networks.

Customer Notification: Introducing New QR Code CardsWed Jul 19 2023
Starting July 2023, nanotools will implement the following changes on the shipment of AFM probes:
The traditional A5 format Flyers
1. Handling HDC/DLC tips
2. nanotools AFM probes get mobile
will no longer be included in the shipments.
They will be replaced by smaller 8.5 x 5.5 cm cards with QR codes linking users to the same information.
There are no changes to the products, packaging size and material or manufacturing location.
Why are we making this change?
This is part of our efforts to reduce nanotools carbon footprint.
The new cards help to
- Reduce transportation emissions (lighter shipments)
- Minimize waste at customer sites

Domain-wall magnetoelectric coupling in multiferroic hexagonal YbFeO3 filmsThu Jun 22 2023
Electrical modulation of magnetic states in single-phase multiferroic materials, using domain-wall magnetoelectric (ME) coupling, can be enhanced substantially by controlling the population density of the ferroelectric (FE) domain walls during polarization switching. *
In the article “Domain-wall magnetoelectric coupling in multiferroic hexagonal YbFeO3 films”, Xin Li, Yu Yun, Arashdeep Singh Thind, Yuewei Yin, Qiang Li, Wenbin Wang, Alpha T. N’Diaye, Corbyn Mellinger, Xuanyuan Jiang, Rohan Mishra and Xiaoshan Xu investigate the domain-wall ME coupling in multiferroic h-YbFeO3 thin films, in which the FE domain walls induce clamped antiferromagnetic (AFM) domain walls with reduced magnetization magnitude. *
