Pick‐and‐Place Grippers with Tunable Adhesion from Capped Soft Hollow Pillar Structure

Advanced Materials Technologies, EarlyView.
Mushroom‐shaped soft hollow pillars (SHPs) with a mushroom cap, or capped SHPs (C‐SHPs) are introduced for improved tunable adhesion under pneumatic actuation. The mushroom cap optimizes stress distribution and alters crack initiation on the contact interface, leading to significantly improved adhesion strength and tunability.

How to Manufacture Photonic Metamaterials

Advanced Materials Technologies, EarlyView.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

The Influence of the Supporting Substrate on Single‐Particle Circular Differential Scattering of DNA Assembled Nanorod Dimers

Advanced Optical Materials, EarlyView.
For most microscopy measurements the sample is placed on a substrate, which causes symmetry breaking, especially relevant for chiral plasmonic nanostructures. DNA origami mediated X‐shaped AuNR dimers showing high structural purity in solution, exhibit significant diversity in lineshapes and signal intensities for their circular differential scattering

TADF Host Engineering for Improved Pure Blue Matrix‐Free Hyperfluorescent OLEDs with Ultranarrow Emission

Advanced Optical Materials, EarlyView.
This work presents the development of efficient blue thermally activated delayed fluorescent (TADF) materials that perform well without doping, enabling simplified, matrix‐free hyperfluorescence (MFHF) OLEDs. When combined with encapsulated narrow‐band emitters, the TADF materials serve as effective hosts resulting in pure blue, ultranarrow emission ...

Co‐Solvent‐Aided Opto‐Thermophoretic Printing of Gold Nanorod Assemblies

Advanced Optical Materials, EarlyView.
A focused laser beam creates a thermal gradient, driving the gold nanorods and polymer coils toward the heated region of the glass substrate, i.e, the laser spot. After the adsorption of the polymer on the gold surface, the nanorods start to assemble onto the surface in a ring‐shaped pattern that grows radially until the beam is turned off.

Nd(III)‐Based Temperature‐Independent Manometer and Pressure‐Independent Thermometer with Slow Relaxation of Magnetization

Advanced Optical Materials, EarlyView.
The Neodymium(III) macrocyclic complex [NdL(CF3SO3)3] serves as a non‐contact, bifunctional sensor for temperature and pressure, displaying field‐induced Single Molecule Magnet (SMM) behavior. At 3 GPa, triflate rotations halt, triggering a disorder‐order phase transition from centrosymmetric phase α to noncentrosymmetric high‐pressure phase β.
