s-SNOM Imaging for Ultrahigh Resolution Displays
by J. Karst, F. Sterl, H. Linnenbank, T. Weiss, M. Hentschel and H. Giessen
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.
Protein nanoribbons template enamel mineralization
by Y. Bai, Z. Yu, L. Ackerman, Y. Zhang, J. Bonde, W. Li, Y. Cheng and S. Habelitz
Dental enamel is a true masterpiece of nature’s engineering. Structural analysis using AFM suggests their twisted structure, however, does not provide chemical identity.
Strong coupling between phonon polaritons & organic molecules
by Andrei Bylinkin, Martin Schnell, Marta Autore, Francesco Calavalle, Peining Li, Javier Taboada-Gutitierrez, Song Liu, James H. Edgar, Felix Casanova, Luis E. Hueso, Pablo Alonso-Gonzalez, Alexey Y. Nikitin and Rainer Hillenbrand
Light plays an essential role in modern science and technology, with applications ranging from fast optical communication to medical diagnosis and laser surgery.
Near-field encounter: nano-PL and nano-Raman meets s-SNOM
by Alireza Fali, Tianyi Zhang, Jason Patrick Terry, Ethan Kahn, Kazunori Fujisawa, Bernd Kabius, Sandhaya Koirala, Yassamin Ghafouri, Da Zhou, Wenshen Song, Li Yang, Mauricio Terrones, and Yohannes Abate
A study led by University of Georgia researchers announces the successful use of a new nanoimaging technique that will allow researchers to test and identify these materials in a comprehensive way at the nanoscale for the first time. Now, there’s a way to experiment with new materials for our big ideas at a really, really small scale.
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.
