NANOSENSORS Decoding Morphology in Organic Solar Cells with NANOSENSORS™ PPP-NCHAu AFM Probes - news

Decoding Morphology in Organic Solar Cells with NANOSENSORS™ PPP-NCHAu AFM ProbesThu Aug 28 2025

Published in Nature Communications (March 2023), the article by Zhenrong Jia et al. investigates a novel ultra-narrow bandgap non-fullerene acceptor, BTPSeV-4F, which effectively suppresses triplet exciton formation in organic photovoltaic devices. This molecular design significantly reduces non-radiative losses, enabling tandem organic solar cells (TOSCs) to reach a power conversion efficiency of 19%, with record-setting short-circuit current density in the rear sub-cell.
High-resolution morphological characterization played a crucial role in correlating device performance with film formation and nanostructure. The authors used tapping mode-AFM
with gold-coated silicon cantilevers (PPP-NCHAu) from NANOSENSORS™ , known for their exceptional stability and tip precision.

Decoding the Ubiquitin Code: How the RQT Complex Clears Colliding RibosomesMon Aug 11 2025

Matsuo et al., recently published a landmark study in Nature Communications (vol. 14, article 79, Jan 10 2023). , looking at how cells recognize and resolve ribosome collisions—a critical event in obeying translational fidelity and avoiding protein quality control failure.

The researchers employed a combination of molecular genetics, biochemical assays, ubiquitin-binding studies, and advanced imaging. Key steps included mutational deletion of ubiquitin‐binding domains in RQT subunits, affinity assays for K63-linked ubiquitin chains, and highspeed atomic force microscopy (HSAFM) to visualize complex behavior at the molecular level. Notably, they used intrinsically disordered regions of Rqt4 mapped by realtime HSAFM.

Strong, tough, rapid-recovery, and fatigue-resistant hydrogels made of picot peptide fibresThu Aug 07 2025

Bin Xue et al. have presented a novel class of biomimetic hydrogels that simultaneously exhibit high stiffness, toughness, fatigue resistance, and ultrafast mechanical recovery—properties that are notoriously difficult to combine in conventional polymeric systems. Their design is inspired by the architecture of mussel foot proteins and is centered around self-assembling peptide fibres termed “picot fibres”, which act as hierarchical load-bearing domains.

NANOSENSORS Enhanced Exiton-Plasmon Interaction Enabling Observation of Near-Field Photoluminescence in a WSe2-Gold Nanoparticle Hybrid System - news

Enhanced Exiton-Plasmon Interaction Enabling Observation of Near-Field Photoluminescence in a WSe2-Gold Nanoparticle Hybrid SystemThu Jun 05 2025

Monolayer transition metal #dichalcogenides, such as tungsten diselenide, have recently attracted considerable attention due to their reduced dielectric screening and direct bandgap, which result in high exciton binding energy and strong #photoluminescence.*
The integration of monolayer transition metal dichalcogenides with #plasmonic #nanoparticles enhances their optoelectronic properties through localized surface #plasmons and strong electromagnetic confinement. *
In the article “Enhanced Exciton–Plasmon Interaction Enabling Observation of Near-Field Photoluminescence in a WSe2–Gold Nanoparticle Hybrid System” Anastasia Romashkina, Sandhya Sushil, Angela I. Barreda, Zlata Fedorova, Fatemeh Abtahi, Nathan Doolaard, Zifei Zhang, Christian Helgert, Isabelle Staude, Falk Eilenberger, Thomas Pertsch and Bayarjargal N. Tugchin investigated the photoluminescence response of the hybrid system of monolayer tungsten diselenide and gold nanoparticle arrays through #nearfieldmapping. *
Their study demonstrated a significant enhancement of the excitonic emission by the excited gold nanoparticles via near-field interaction. *
Anastasia Romashkina et al. examined the impact of exciton–plasmon-polariton coupling on the far-field response of the hybrid system. *
There, they observed the phenomenon of exciton-induced transparency, which indicates the intermediate coupling regime and helps resonantly enhance the light-matter interaction in monolayer tungsten diselenide.*
The second harmonic generation intensity from the hybrid system was shown to follow the linear spectral response of the hybrid system, thereby demonstrating the enhanced coupling between surface plasmons and excitons.
Anastasia Romashkina et al.’s research offers insights into the impact of intermediate coupling on the optical properties of hybrid exciton–plasmon systems, which is crucial for the development of advanced #nanophotonicdevices. *
The authors investigate the near-field optical response of the hybrid system with a #scatteringtypeNearfieldopticalMicroscope (#sSNOM), which allows for high-resolution imaging of the evanescent fields of a sample by analyzing the light scattered by the #AFMtip. Figure 2 in the cited article shows the scheme of the used setup. The s-SNOM is based on a tapping-mode #atomicforcemicroscope and uses a tip view #AFMprobe ( NANOSENSORS AdvancedTEC ATEC-NCAu https://www.nanosensors.com/advanced-tip-at-the-end-of-the…) that oscillates above the sample with an amplitude of about 40 nm and a frequency of Ω = 275 kHz. *

NanoWorld Tunable and parabolic piezoelectricity in hafnia under epitaxal strain - news

Tunable and parabolic piezoelectricity in hafnia under epitaxal strainMon May 19 2025

#Piezoelectrics are a class of #functionalmaterials that have been extensively used for application in modern electro-mechanical and mechatronics technologies. *
The sign of longitudinal piezoelectric coefficients is typically positive but recently a few ferroelectrics, such as ferroelectric polymer poly(vinylidene fluoride) and van der Waals ferroelectric CuInP2S6, were experimentally found to have negative piezoelectricity.
In the article “Tunable and parabolic piezoelectricity in hafnia under epitaxial strain” Hao Cheng, Peijie Jiao, Jian Wang, Mingkai Qing, Yu Deng, Jun-Ming Liu, Laurent Bellaiche, Di Wu and Yurong Yang, using first-principles calculation and measurements, show that the sign of the longitudinal linear piezoelectric coefficient of HfO2 can be tuned from positive to negative via epitaxial strain. *
Nonlinear and even parabolic piezoelectric behaviors are further found at tensile epitaxial strain. *
This parabolic piezoelectric behavior implies that the polarization decreases when increasing the magnitude of either compressive or tensile longitudinal strain, or, equivalently, that the strain increases when increasing the magnitude of electric field being either parallel or antiparallel to the direction of polarization. The unusual piezoelectric effects are from the chemical coordination of the active oxygen atoms. *
These striking piezoelectric features of positive and negative sign, as well as linear and parabolical behaviors, expand the current knowledge in piezoelectricity and broaden the potential of piezoelectric applications towards electro-mechanical and communications technology. *

sQube® colloidal AFM probes CP-CONT-PS-B and CP-PNPL-SiO-B with soft AFM cantilevers and small colloidal particles in the range of 3.5 μm help the researchers assess the cell nuclei stiffnessThu May 15 2025

“Eukaryotic cells show an astounding ability to remodel their shape and cytoskeleton and to migrate through pores and constrictions smaller than their nuclear diameter… Our results contribute to a more comprehensive mechanistic understanding of the complex interplay between confinement, the nucleus, and the cytoskeleton during mesenchymal cell migration.”
Our colloidal AFM probes CP-CONT-PS-B and CP-PNPL-SiO-B with soft AFM cantilevers and small colloidal particles in the range of 3.5 μm help the researchers assess the cell nuclei stiffness and conclude that it can be considered as an elastic object with a Poisson ratio of approx. 0.40.
