Hierarchical Protofilament Intertwining Rules the Formation of Mixed-Curvature Amyloid Polymorphs

Giovanni Dietler, Henning Paul-Julius Stahlberg, Meltem Tatli, Francesco Simone Ruggeri, Jiangtao Zhou, Salvatore Assenza, Raffaele Mezzenga

Amyloid polymorphism is a hallmark of almost all amyloid species, yet the mechanisms underlying the formation of amyloid polymorphs and their complex architectures remain elusive. Commonly, two main mesoscopic topologies are found in amyloid polymorphs cha ...

3D printed fiber-optic nanomechanical bioprobe

Sandor Kasas, Jiangtao Zhou, Yiping Wang, Yuguang Chen

Ultrasensitive nanomechanical instruments, e.g. atomic force microscopy (AFM), can be used to perform delicate biomechanical measurements and reveal the complex mechanical environment of biological processes. However, these instruments are limited because ...

Fiber-interface directional coupler inscribed by femtosecond laser for refractive index measurements

Jiangtao Zhou, Zhechen Zhang, Yiping Wang, Jiachen Wang

A novel fiber-interface directional waveguide coupler was inscribed on the surface of a coreless fiber by femtosecond laser, and was successfully applied to highly sensitive refractive index (RI) measurements. The primary arm was first inscribed to couple ...

Effects of sedimentation, microgravity, hydrodynamic mixing and air-water interface on alpha-synuclein amyloid formation

Giovanni Dietler, Giovanni Longo, Francesco Simone Ruggeri, Jiangtao Zhou

The formation of amyloid fibrils is a characterizing feature of a range of protein misfolding diseases, including Parkinson's disease. The propensity of native proteins to form such amyloid fibril, both in vitro and in vivo, is highly sensitive to the surr ...

Europium-Doped CsPbI2Br for Stable and Highly Efficient Inorganic Perovskite Solar Cells

Michael Graetzel, David Lyndon Emsley, Giovanni Dietler, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Jingshan Luo, Dominik Józef Kubicki, Daniel Prochowicz, Zaiwei Wang, Jiangtao Zhou, Seckin Akin, Wanchun Xiang

All-inorganic perovskite films hold promise for improving the stability of perovskite solar cells (PSCs). However, the 3D alpha phase of narrow-bandgap inorganic perovskites is thermodynamically unstable at room temperature, limiting the development of hig ...
