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.

Detecting Early-Stage Cohesion Due to Calcium Silicate Hydration with Rheology and Surface Force ApparatusWed Jul 19 2023
Extremely robust cohesion triggered by calcium silicate hydrate (C–S–H) precipitation during cement hardening makes concrete one of the most commonly used man-made materials. *
In the article “Detecting Early-Stage Cohesion Due to Calcium Silicate Hydration with Rheology and Surface Force Apparatus” Teresa Liberto, Andreas Nenning, Maurizio Bellotto, Maria Chiara Dalconi, Dominik Dworschak, Lukas Kalchgruber, Agathe Robisson, Markus Valtiner and Joanna Dziadkowiec present a proof-of-concept study, in which they seek an additional nanoscale understanding of early-stage cohesive forces acting between hydrating model tricalcium silicate (C3S) surfaces by combining rheological and surface force measurements.
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. *

Feasibility of wear reduction for soft nanostructured thin film through enhanced elastic recoverability and contact stress reliefTue Jun 13 2023
Feasibility of wear reduction for soft nanostructured thin film through enhanced elastic recoverability and contact stress relief
Over several decades many studies on the reduction of wear of mechanical systems have been conducted. Methods to reduce wear are generally divided into the following categories: applying lubrication, coating with high-hardness materials, and surface texturing. * Several studies have reported that coatings with higher hardness show more wear than those with lower hardness. From […]

Single Electrochemical Impacts of Shewanella oneidensis MR-1 Bacteria for Living Cells Adsorption onto a Polarized Ultramicroelectrode SurfaceThu Jun 08 2023
In the past few years, several novel analytical methods with high sensitivity and spatial-temporal resolution that enable qualitative and quantitative analysis at single-cell and subcellular levels have emerged. *
The four major areas of analytical methods usually reported are electrochemical analysis, super-resolution microscopy, mass spectrometry imaging, and microfluidics. *
Electrochemistry offers a distinctive and essential advantage in its ability to combine high sensitivity and easy handling with a light and portable instrumentation, thereby enabling miniaturized devices for micro-biosensor applications. *

Today we lovingly remember the Swiss physicist Heinrich Rohrer, born on 06.06.1933, who invented the Scanning Tunneling Microscope (STM) together with Gerd Binnig.
STM allows mapping conductive samples with atomic resolution using quantum tunnelling.
PENICILLIN-BINDING PROTEIN 1 (PBP1) OF STAPHYLOCOCCUS AUREUS HAS MULTIPLE ESSENTIAL FUNCTIONS IN CELL DIVISIONWed May 31 2023
Bacterial cell division is a complex process requiring the coordination of multiple components to allow the appropriate spatial and temporal control of septum formation and cell scission. *
Peptidoglycan (PG) is the major structural component of the septum, and recent studies by Katarzyna Wacnik et al., in the human pathogen Staphylococcus aureus have revealed a complex, multistage PG architecture that develops during septation. *
Penicillin-binding proteins (PBPs) are essential for the final steps of PG biosynthesis; their transpeptidase activity links the peptide side chains of nascent glycan strands. PBP1 is required for cell division in S. aureus. *
Operando Characterizations of Light-Induced Junction Evolution in Perovskite Solar CellsTue May 30 2023
Light-induced performance changes in metal halide perovskite solar cells (PSCs) have been studied intensively over the last decade, but little is known about the variation in microscopic optoelectronic properties of the perovskite heterojunctions in a completed device during operation.*
For the article “Operando Characterizations of Light-Induced Junction Evolution in Perovskite Solar Cells “ Chuanxiao Xiao, Yaxin Zhai, Zhaoning Song, Kang Wang, Changlei Wang, Chun-Sheng Jiang, Matthew C. Beard, Yanfa Yan and Mowafak Al-Jassim combined Kelvin probe force microscopy and transient reflection spectroscopy techniques to spatially resolve the evolution of junction properties during the operation of metal-halide PSCs and study the light-soaking effect.
