Microfluidic Spinning of PEDOT:PSS Microfibers for Nerve Guidance Conduits

open access: yesAdvanced Materials Technologies, EarlyView.
This publication explores the fabrication of microfluidically spun PEDOT:PSS microfibers for conductive nerve guidance conduits (NGCs). It details the spinning process, fiber characterization, and biocompatibility assessment. The study highlights the fibers' mechanical and electrical properties, non‐cytotoxicity, and potential for nerve regeneration or

Combinatorial doping of TiO_2 with platinum (Pt), chromium (Cr), vanadium (V), and nickel (Ni) to achieve enhanced photocatalytic activity with visible light irradiation [PDF]

open access: yes, 2010
Titanium dioxide (TiO_2) was doped with the combination of several metal ions including platinum (Pt), chromium (Cr), vanadium (V), and nickel (Ni). The doped TiO_2 materials were synthesized by standard sol-gel methods with doping levels of 0.1 to 0.5 ...

Rapid Electro‐Thermal Micro‐Actuation of Flat Optics Enabled by Laser‐Induced Graphene on Colorless Polyimide Substrates

open access: yesAdvanced Optical Materials, EarlyView.
Laser‐induced graphene (LIG) on a colorless polyimide (CPI) substrate functions as both an electrical heater and a heat spreader, enabling rapid electro‐thermo‐optic actuation. The system achieves reflective beam scanning up to 2 kHz and diffractive beam steering with 0.5‐millidegree resolution and a 0.9 s response time, showcasing LIG‐CPI as a soft ...

Biomimetic Orthogonal Removal of Arylacyl Protecting Groups from the C‐Terminus of Substituted Amino Acids and Oligopeptides via Flavin N(5)‐iminium Covalent Adducts

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract Flavin co‐factors and other flavin derivatives are traditionally associated with one‐ or two‐electron redox reactions. Flavins also form covalent intermediates with a variety of substrates. While extensive attention has focused on reactions at the C(4a) position of the flavin ring, recent interest has shifted toward the dynamic potential of ...
