Free-standing films of metal octaethylporphyrins (MOEPs) were prepared for the first time by a physical vapor deposition on surface of an ionic liquid (IL). Different from those on solid surfaces, the as-obtained films were very compact and with plannar structure. The monitoring of time-dependent process indicated that the high surface energy of IL and the strong π…π interaction between MOEP molecules played key roles in forming such films. Furthermore, the as-obtained film showed good transferability, which made it possible to be easily transferred to any substrates for further device application. More importantly, the prototype photodetectors based on free-standing films of MOEP showed ultra flexibility, mechanical stability, and durability.

The miniaturization of light-emitting diodes (LEDs) is pivotal in ultrahigh-resolution displays. Metal-halide perovskites promise efficient light emission, long-range carrier transport and scalable manufacturing for bright microscale LED (micro-LED) displays. However, thin-film perovskites with inhomogeneous spatial distribution of light emission and unstable surface under lithography are incompatible with the micro-LED devices.

Article Synopsis
- Transition metal oxides, like MnO, show great promise as anodes for flexible electrodes but face challenges such as low conductivity and poor cycling performance.
- A new method called "spontaneous complexation and exfoliation" creates flexible thin-film electrodes using MnO nanocrystals and reduced graphene oxide (rGO), improving their mechanical flexibility and lithium-ion storage capacity.
- The resulting flexible anodes deliver around 1220 mAh/g over 1000 cycles with high-rate capacity, while maintaining performance even under bending, highlighting their potential for advanced energy storage solutions.

Free-standing capillary microfluidic channels were directly printed over printed electrodes using a particle/polymer mixture to fabricate microfluidic-electrochemical devices on polyethylene terephthalate (PET) films. Printed devices with no electrode modification were demonstrated to have the lowest limit of detection (LOD) of 7 μM for sensing glucose. The study shows that both a low polymer concentration in the mixture for printing the microfluidic channels and surface modification of the printed microfluidic channels using 3-aminopropyltrimethoxysilane can substantially boost the device's performance.

The adsorption of (X = Ni, Pd, and Pt) nanoclusters is simulated by using first-principles methods on MgO(100) and on a MgO monolayer supported on Ag(100), considering the presence of interfacial oxygen. On both the free-standing MgO surface and MgO/Ag, all clusters exhibit robust adhesion and negative charge transfer. molecular dynamics calculations at 200 K demonstrate the stability of the nanoparticles on the MgO/Ag support.

Smart shape-memory DNA hydrogels, which can respond to various types of external stimuli and undergo macroscopic shape deformations, have shown great potential in various applications. By constructing free-standing films, the deformation and response properties of these hydrogels can be further enhanced, and visualized deformation can be achieved. However, DNA hydrogels that can exhibit rapid and high-degree shape deformations, such as the inverse shape deformations, are still lacking.
