Unlocking the nanoworld of plant cells by multimodal s-SNOM

by A. M. Charrier, A. C. Normand, A. Passian, P. Schaefer and A. L. Lereu

A research consortium from Institut Fresnel, CINaM and ORNL, used multimodal s-SNOM to correlate mechanical properties, optical constants and chemical distribution of the wood cell wall in-situ. Using a combination of all these AFM modes the researchers followed a delignification process that enabled establishing factors preventing the complete removal of lignin, an important process for smart resource utilization in the wood industry.

sSNOM probes molecular orientation of organic semiconductors

by N. Mrkyvkova, A. Cernescu, Z. Futera, A. Nebojsa, A. Dubroka, M. Sojkova, M. Hulman, E. Majkova, M. Jergel, P. Siffalovic and F. Schreiber

Researchers from the Center of Advanced Material Applications in Bratislava investigated the molecular orientation and mapped the heterogeneity of discreet molecular structures in semiconducting organic films using the light-induced anisotropic s-SNOM response of vibrational modes to reveal the defects in molecular orientation. They developed a method to measure molecular orientation using both amplitude and phase s-SMOM signal.

High-performance crystalline nanocellulose

by B. Alonso-Lerma, L. Barandiaran, L. Ugarte, I. Larraza, A. Reifs, R. Olmos-Juste, N. Barruetabeña, I. Amenabar, R. Hillenbrand, A. Eceiza and R. Perez-Jimenez

Nanocellulose is the most abundant linear biopolymer on our planet. Structural analysis using AFM suggests their twisted structure, however, does not provide chemical identity.

s-SNOM & nano-FTIR study from a single nanocellulose particle paved the way towards fabrication of biocompatible biosensors for wearable or implant devices for diagnosis.

nano-FTIR shine new light on making 2D polymers

by L. Grossmann, B. T. King, S. Reichlmaier, N. Hartmann, J. Rosen, W. M. Heckl, J. Björk and M. Lackinger

An international research team with members from Linköping University, the Deutsches Museum and the Technical University of Munich, among others, has developed a method to manufacture two-dimensional polymers with the thickness of a single molecule. The polymers are formed on a surface by the action of light. The discovery paves the way to new ultrathin and functional materials and has been published in Nature Chemistry.

Correlative nano-imaging: KPFM complements s-SNOM

by Ting-Xiao Qin, En-Ming You, Mao-Xin Zhang, Peng Zheng, Xiao-Feng Huang, Song-Yuan Ding, Bing-Wei Mao and Zhong-Qun Tian

Perovskites become an emerging material for solar cells with rapidly boosted power conversion efficiency. The polycrystalline nature of perovskite active layers leads to the unavoidable existence of numerous nanometer-sized grain boundaries (GBs). Understanding the impact of GBs on solar cell performance is crucial for the design of perovskite active layer structures.
