Summary: The study examines the flexocaloric and elastocaloric effects in a 0.66Pb(Mg1/3Nb2/3)O-3-0.34PbTiO(3) single crystal. It is found that the flexocaloric effect in this crystal is predominantly driven by elastic contribution rather than polarization. The maximum flexocaloric and elastocaloric temperatures were observed under different stress levels.

Summary: Adipogenesis is regulated by a transcriptional cascade involving CEBP and PPAR family members and hormonally induced pathways. Tm7sf2 gene is involved in cholesterol biosynthesis and modulates the expression of the master gene of adipogenesis PPAR gamma, affecting adipose tissue homeostasis. Loss of Tm7sf2 impairs adipocyte differentiation by affecting adipogenic regulators and insulin signaling, indicating its importance in maintaining metabolic health.

Summary: 2D ultrafine nanomaterials, particularly boron nitride nanosheets, have shown significant promise in biomedical applications. This study successfully exfoliated BN nanosheets using tip sonication, resulting in few-layered nanosheets with a narrow size distribution. The addition of pluronic acid F127 improved the production yield and stability of the BNNs in aqueous solution. Cytotoxicity studies revealed that the BNNs coated with pluronic acid exhibited low toxicity to HeLa cells and demonstrated high internalization and preferential distribution in the cell cytoplasm.

Summary: In this study, the authors show that cells can take two mechanistically distinct paths in the same transition paradigm when driven by the similar proneural factors Ascl1 and Ngn2. Ascl1 dismantles the pluripotency network and installs neuronal and trophoblast cell fates, while Ngn2 generates a neural stem cell-like intermediate supported by incomplete shutdown of the pluripotency network.

Summary: To fully utilize the potential of 3D printing, particularly in the case of semisolid extrusion (SSE), the technological challenges need to be addressed. This study focuses on investigating the physicochemical properties of natural polymers, specifically alginate hydrogel, for 3D printing tablets that are easy to swallow. By adding sorbitol as a plasticizer, the aim is to improve the swallowability of the tablets. Different concentrations of sorbitol solution are evaluated to determine the best composition in terms of printing and technological properties. The results highlight a predictable relationship between the amount of sorbitol loaded and the residual mass of the final platforms.

Summary: In this study, we characterized the organization levels of amyloid fibrils from proteins with similar structures using various methods including VCD, ECD, cryo-EM, and TEM. Our results showed that small changes in protein structure or preparation conditions led to significant differences in the structure and architecture of the fibrils. Although the secondary structure and protofilament twist varied, the mesoscopic structure of the fibrils remained relatively similar. These findings contribute to understanding the indeterministic nature of fibril formation.

Summary: This study aimed to develop 3D-printed hydrogels as multifunctional wound dressings containing phytotherapeutic agents. Results showed that blending xanthan gum (XAN) overcame the challenges associated with sodium alginate (ALG) in terms of printability and shape fidelity. Clove essential oil (CLV) was successfully incorporated into the 3D-printed hydrogels, exhibiting long-term release and enhanced antioxidant and antibacterial activity. Additionally, CLV showed potential anti-inflammatory effects and had no toxic effect on NHDF cells. Overall, this study highlights the potential benefits of incorporating natural phytotherapeutics into 3D-printed hydrogels for wound healing.

Summary: Polar discontinuities and compositional/structural changes at oxide interfaces can result in various electronic and ionic phenomena. This study investigates the relationship between polar discontinuities and local chemistry at grain boundaries in polycrystalline ferroelectric ErMnO3. It is found that the polycrystalline material develops charged grain boundaries with enhanced electronic conductance. The observed changes in composition are determined by structural phenomena rather than electrostatics, leading to changes in electronic transport behavior.

Summary: This study used polycaprolactone (PCL) and melt electrowriting (MEW) technique to fabricate scaffolds coated with superparamagnetic iron oxide nanoparticles (SPIONs) and silica-coated-SPIONs (Si-SPIONs). The hydrophilicity of the scaffolds was improved by alkaline treatment. The scaffolds showed good biocompatibility. The alkaline-treated scaffolds and SPIONs/Si-SPIONs-coated scaffolds exhibited higher pre-osteoblastic cell adhesion and proliferation efficiency. All samples were able to generate heat when subjected to an alternating magnetic field, useful for hyperthermia treatment.

Summary: This study synthesized electroconductive silane-modified gelatin-poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) scaffolds to simulate the chemistry and piezoelectricity of bone. The scaffolds were functionalized with polydopamine (PDA) inspired by mussels to enhance hydrophilicity, cell interaction, and biomineralization. Analysis showed that the PDA-coated scaffolds had improved electrical resistance, hydrophilicity, compressive strength, modulus, and biomineralization capability. The scaffolds also promoted the viability, adhesion, proliferation, alkaline phosphatase expression, and HA deposition of MG-63 cells, indicating their potential for bone regeneration.

Summary: This study investigated the antimicrobial and mechanical properties of dental floss coated with chitosan or chitosan + mesoporous bioactive glass nanoparticles. The coatings showed significant ability to inhibit bacterial growth after 24 hours, although the impact was minimal at 3 hours. Furthermore, the addition of these layers improved the tensile strength of the floss, making it more effective for cleaning between teeth. Enhanced investigations of these composites are therefore proposed due to their potential in promoting oral health.

Summary: In this study, CBS glass/Al2O3 composites were developed for LTCC applications based on a CaO-B2O3-SiO2 (CBS) glass system with a high boron content. The study revealed that the softening of glass and interfacial reaction between the glass and Al2O3 were the two most important factors affecting LTCC's densification process. Real-time shrinkage rate of LTCC during sintering was successfully simulated, and it was proven that the formation of the CaAl2(BO3)O phase played a significant role in reducing glass viscosity and promoting dense structure formation. The resulting LTCC composite exhibited excellent performance for high-frequency applications.

Summary: In this study, the disordering caused by swift heavy ion irradiation in two different compositions of pyrochlore structures was investigated. X-ray diffraction, Raman spectroscopy, and high-resolution transmission electron microscopy were used to analyze the samples before and after irradiation. It was found that both compositions underwent amorphization due to irradiation, with a slower rate observed in Nd1.8Zr2.2O7.1. The irradiation-induced modified track region in Nd1.8Zr2.2O7.1 consisted of defect-rich pyrochlore structure, anion-deficient fluorite structure, and amorphous domains.

In this study, a combination of first-principles calculations and experimental observation was used to investigate the correlation among sintering behavior, crystal structure, bonding nature, and microwave dielectric properties of LnPO(4) (Ln = Eu, Pr) ceramics. The research findings systematically clarify the optimized effect and micromechanism of lanthanides on the dielectric properties of monazite ceramics, providing insights into the design and enhancement of microwave dielectric materials.

Summary: The study investigates the frictional and wear behaviors of carbon fiber-reinforced SiC ceramic matrix composites with different fiber orientations mating with ceramic balls. The results show that fiber orientation significantly affects the friction and wear properties of the composites. Pads with randomly arranged fibers demonstrate better friction stability and lower wear volume, potentially suitable for bearing material applications. The research also explores the factors influencing the formation of continuous tribo-film and identifies abrasive wear and oxidation wear as the dominant wear mechanisms for the friction pairs.
