In Situ Amine Formation to Modulate MOF‐Derived PdIn N‐Doped Carbon Catalysts
Advanced Materials, EarlyView.An amine‐assisted approach converts PdIn‐MOF into PdIn intermetallic nanoparticles embedded in N‐doped carbon. In situ‐generated amines trigger early Pd nucleation, producing smaller PdIn domains than direct pyrolysis. Amine sterics and basicity tune composition and particle size, while solvent and amine co‐determine textural features.

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells
Advanced Materials, EarlyView.This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

Dynamic Optical Lattices Through Conducting Polymer‐Gated Confinement
Advanced Materials, EarlyView.The conducting polymer gate is incorporated into organic dielectric lattices to control the dynamic switching of nonlocal Mie resonances in the visible/NIR regions. The “closed gate” from oxidized PEDOT confines the light within dielectric nanocylinders and activates nonlocal Mie resonances, while the “opened gate” from reduced PEDOT facilitates ...

High-Order Modes Micro-Knot Excited by a Long-Period Fiber Grating
Sensors, 2017 We suggest a fiber micro-knot fabricated on a long-period fiber grating. The long-period fiber grating excites high-order modes into the micro-knot and transfers the output back to the Gaussian mode.

Widely tunable long-period fibre gratings
Electronics Letters, 1999 The authors report the realisation of a new type of long-period fibre grating with an enhanced temperature sensitivity of 8O nm/100/spl deg/C by the use of specially-designed fibre structures incorporating polymers. These new gratings should enable broadly tunable filters for communications systems.
