Summary: A tubular-shaped Janus nanoparticle based on polydopamine that responds to near-infrared, magnetic, and pH stimuli is reported. The robust tubular polydopamine structure was obtained by optimizing the halloysite template-to-dopamine ratio during synthesis. The inner and outer surfaces of the tube were exposed at different steps of the template-sonication-etching process, enabling the differential surface modification of these surfaces. The resulting magnetic Janus nanoparticles responded to pH, temperature, and magnetic fields, and the release rates of adsorbed doxorubicin from the nanoparticles were influenced by these stimuli.

Summary: Recent advances in composite hydrogels have shown that incorporating liquid metals (LM) microdroplets can enhance material properties and enable specialized stimuli-responsive functionalities. LM microdroplets can act as initiators for ultra-fast polymerization and also influence the resulting hydrogel material and stimuli-responsive characteristics. Experimental results demonstrate that higher ratios of LM lead to improved stimuli-responsive behaviors, such as swelling and ionic actuation. These biocompatible LM-hydrogel composites open up new opportunities for soft robotics and biomedical applications.

Summary: Since the successful separation of different cucurbit[n]uril homologues in 2001, the field of cucurbit[n]uril supramolecular chemistry has rapidly developed. The combination of Q[n] cavity size and various external stimuli has led to the creation of various Q[n]-based mechanically interlocked molecules (MIMs), including (pseudo)rotaxanes, catenanes, dendrimers, and poly(pseudo)rotaxanes. This review article highlights the important advancements in the field of Q[n]-based MIMs over the past two decades, discusses examples of heterowheel (pseudo)rotaxanes and poly(pseudo)rotaxanes involving Q[n]s, and reflects on the opportunities and challenges of constructing Q[n]-based stimuli-responsive MIMs.

Summary: This study demonstrates a dual-stimuli cooperative responsive hydrogel microactuator by asymmetric fabrication via femtosecond laser direct writing. The dual response of the hydrogel microstructure is achieved through the use of responsive hydrogel with functional monomer 2-(dimethylamino)ethyl methacrylate. Raman spectra of the hydrogel microstructures suggest that the pH and temperature response of the hydrogel is generated by the changes in tertiary amine groups and hydrogen bonds, respectively. The asymmetric hydrogel microstructures show opposite bending direction when being heated to high temperature or exposed to acid solution, and can independently accomplish the grasp of polystyrene microspheres.

Summary: Polymer brushes can be produced by surface-initiated polymerization using initiators or chain transfer agents. This manuscript presents an alternative method using non-covalent host-guest interactions to immobilize initiators for atom transfer radical polymerization. These non-covalent initiators can generate supramolecular polymer brushes with film thicknesses over 100 nm.

Summary: A mesoporous silica-based drug delivery system was synthesized by conjugating a PNIPAm-PAAm copolymer onto the mesoporous silica surface. The copolymer acts as a gatekeeper that responds to temperature and pH changes, allowing controlled drug delivery. The system exhibited good biocompatibility and was readily taken up by MDA-MB-231 cells, making it suitable for drug delivery applications where sustained drug release at higher temperatures is required.

Summary: MOF materials with adjustable pore structure and polymetallic sites have been explored as electrocatalysts for OER. Bimetallic materials show higher electrocatalytic activity than monometallic materials, while carbon-coated and doped MOF catalysts exhibit stable and good OER activity. The synergistic interaction between polymetallic active sites effectively improves the intrinsic activity of MOF on OER.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.

Summary: First principles calculations were used to investigate the pathway for methylation of benzene with methane catalyzed by MFI type zeolite-supported Co species. The strong adsorption of benzene on Co is found to lower the activation energy for methane dissociation and promote the formation of toluene precursor. The activation energy of methane dissociation is also affected by the Al-Al distance.
