Summary: This study investigates the behavior of core-shell microparticles with a liquid core under thermal and mechanical loads, establishing analytical models and conducting experiments to validate them. The results demonstrate that the maximum temperature and critical compression force before rupture of core-shell microparticles depend on the liquid, geometry, and material of the shell.

Summary: The study of core/shell pigments is crucial for their application in paints and varnishes. When the pigment contains a high percentage of polyaniline (PANi), it exhibits similar hiding power and blackness to pure PANi. Kaolin-based pigments have lower blackness due to their higher whiteness, while talc-based pigments are more efficient in the dispersion process.

Summary: Core-shell structured nanocarriers have gained attention in recent years due to their wide applications and intriguing properties. However, systematic reviews on stimulus-responsive core-shell structured nanocarriers are uncommon. This review categorizes core-shell structured nanocarriers based on different drug payload methods, highlights controlled release mechanisms achieved through stimulus-response processes, and addresses multifaceted perspectives on the design of core-shell structured materials as drug carriers.

Summary: This study explores a new microfabrication technique for the fabrication of injectable microparticles with a hollow core-shell structure and pulsatile release kinetics. The sudden increase in porosity of the polymeric matrix leads to the formation of a porous path connecting the core to the environment, enabling pulsatile release. The release kinetics of the microparticles were found to be primarily independent of particle geometry but highly dependent on composition. A qualitative technique was developed to study the pH pattern within the particles, and a computational model successfully simulated the particle deformations before release.

Summary: This study presents a straightforward method to synthesize copper sub-microparticles with a green core-shell structure using poly(n-vinyl)pyrrolidone (PVP) as stabilizer. Copper sulfate pentahydrate and glucose were used as precursor and reducing agent, respectively, to prepare Cu@PVP colloids. The presence of PVP eliminated the need for an inert atmosphere during the synthesis, simplifying the process. The morphology and spectroscopic properties of the Cu@PVP colloids were characterized, confirming the formation of a PVP layer around the copper core. These colloids were further utilized in composite thin films for potential antimicrobial applications in combination with a recyclable polymer, polycarbonate (4,4'-(1-methylethylidene)bis(phenol)).

Summary: A self-boosting vaccine has been developed in this study, which utilizes pulsatile release of antigen from core-shell microparticles after a single injection. The self-healing technology used for the antigen core formation prevents organic solvents from damaging the spatial structure. The antigen shell is formed through self-assembly of antigen with an oppositely charged polypeptide. The immune effect and safety evaluation results support the translational potential of this self-boosting core-shell microparticle vaccine.

Summary: This study reports a new nanoplatform for improving the thermal sensitivity of nanothermometry through nonthermally coupled upconversion emissions. By observing the gradual decrease of Er3+ and rapid increase of Tm3+, a significant contrast in intensity ratio and emission colors can be achieved. Introducing Ce3+ further enhances the sensitivity and expands the range of thermochromic color change.

Summary: This study proposes a new type of IL-encapsulated microparticles consisting of a cross-linked copolymer shell and an ionic liquid core as a viable material for CO2 capture. The composition of the shell and the thermal stability affect the encapsulation efficiency of the ionic liquid. Interestingly, there is a trade-off between CO2 absorption capacity and ionic liquid encapsulation.

Summary: This study presents an approach to control the potential profile of III-V-II-VI h-NCs by steering dipole densities at the interface, allowing for control of the optical and electrical characteristics of these heterostructured nanocrystals. The synthesis of h-NCs with atomic precision enables correlation of interfacial dipole moments with the crystals' photochemical stability and optoelectronic performance. Controlled synthesis of heterostructured III-V-II-VI nanocrystals demonstrates that dipole moments formed at the core-shell interface can tune the optoelectronic properties of these nanomaterials and their performance in light-emitting devices.

Summary: The novel core-shell microparticles were fabricated to deliver curcumin by using hydrophobic zein microparticles as the core and hydrophilic cellulose nanocrystals (CNCs) as the shell. The increase of CNCs level delayed the release of curcumin from the microparticles, showcasing the potential of utilizing hydrophilic nanoparticles to stabilize hydrophobic microparticles.
