High-entropy oxides represent a burgeoning class of anode materials for lithium-ion batteries. They reduce the mutual repulsion among constituent elements, enhance structural stability, and effectively mitigate volume changes-induced structural collapse and capacity decay during charge-discharge cycles. However, the complex elemental composition of high-entropy oxides complicate their lithium storage mechanism, particularly the evolution of structural stability during cycling, which requires further elucidation.

Lutein is a fat-soluble carotenoid with diverse biological functions, due to poor water solubility and environmental sensitivity limited it applications in food industry. In this study, β-Lactoglobulin (β-Lg)/γ-polyglutamic acid (γ-PGA) composite emulsion was developed to encapsulate lutein. The best composite was obtained when the ratio of β-Lg and γ-PGA was 1: 1, the β-Lg/γ-PGA composite solution at this ratio was used to encapsulate lutein oil.

Bone regeneration in diabetic patients poses a significant clinical challenge due to persistent hyperglycemia and chronic inflammation, which disrupt the crucial interaction between the immune microenvironment and bone marrow-derived mesenchymal stem cells (BMSCs), thereby impairing osteogenesis. To address this limitation, ultrasonic-responsive barium titanate (BTO) nanoparticles were coated with BMSC membranes (B-TNs) and subsequently integrated into a carboxylated modified silk fibroin (CMS) hydrogel. This resulted in a dual-functional B-TNs@CMS composite hydrogel designed to combine targeted BMSC stimulation with immunomodulatory properties.

Glioblastoma multiforme (GBM) is a highly aggressive brain tumor with limited treatment options due to its resistance to temozolomide (TMZ). This study explores a novel therapeutic approach using engineered cell membrane nanovesicles loaded with SERPINE1 inhibitors to combat TMZ resistance. High-throughput sequencing identified pivotal genes associated with resistance, while the nanovesicles demonstrated excellent stability and the ability to cross the blood-brain barrier.

Glioblastoma remains one of the most lethal malignancies, largely due to its resistance to standard chemotherapy such as temozolomide. This study investigates a novel resistance mechanism involving glioblastoma stem cells (GSCs) and the polarization of M2-type macrophages, mediated by the extracellular vesicle (EV)-based transfer of Clusterin. Using 6-week-old male CD34 humanized huHSC-(M-NSG) mice (NM-NSG-017) and glioblastoma cell lines (T98G and U251), we demonstrated that GSC-derived EVs enriched with Clusterin induce M2 macrophage polarization, thereby enhancing temozolomide resistance in glioblastoma cells.

Cinnamaldehyde (CA), P-Anisaldehyde (PAA), N-heptanal (NHA) and Citronellal (CNA) were used to modify sodium caseinate (SC) as emulsifiers to stabilize β-carotene emulsion, and the binding mechanism of SC and spice aldehyde (SA) was discussed. The results showed that the binding of SA and SC was mainly driven by non-covalent interaction, especially hydrogen bonding. It was also found that CA may form covalent bond with SC through Schiff base reaction.

Depression is a common psychiatric disorder, and monoamine-based antidepressants as first-line therapy remain ineffective in some patients. The synergistic modulation of neuroinflammation and neuroplasticity could be a major strategy for treating depression. In this study, an inflammation-targeted microglial biomimetic system, PDA-Mem@M, is reported for treating depression.

Micelle systems using safe food-grade biopolymers are of particular interest for the encapsulation and delivery of nutrition components. Micellar casein (MC) was assembled using transglutaminase (TGase) to couple with phosphoserine peptide, which enhance the stability of docosahexaenoic acid (DHA) from algae oil. The mechanism behind the construction of MC-phosphoserine peptide and the encapsulation of DHA was explored.

A major challenge facing photodynamic therapy (PDT) is that the activity of the immune-induced infiltrating CD8 T cells is subject to the regulatory T lymphocytes (Tregs), leaving the tumor at risk of recurrence and metastasis after the initial ablation. To augment the antitumor response and reprogram the immunosuppressive tumor microenvironment (TME), a supramolecular photodynamic nanoparticle (DACss) is constructed by the host-guest interaction between demethylcantharidin-conjugated -cyclodextrin (DMC-CD) and amantadine-terminated disulfide-conjugated FFVLGGGC peptide with chlorin e6 decoration (Ad-ss-pep-Ce6) to achieve intelligent delivery of photosensitizer and immunomodulator for breast cancer treatment. The acid-labile -carboxamide bond of DMC-CD is hydrolyzed in response to the acidic TME, resulting in the localized release of DMC and subsequent inhibition of Tregs.

Polyetheretherketone (PEEK) has emerged as a highly promising orthopedic implantation material due to its elastic modulus which is comparable to that of natural bone. This polymer exhibits impressive properties for bone implantation such as corrosion resistance, fatigue resistance, self-lubrication and chemical stability. Significantly, compared to metal-based implants, PEEK implants have mechanical properties that are closer to natural bone, which can mitigate the "stress shielding" effect in bone implantation.

As the global energy crisis intensifies, the development of solar energy has become a vital area of focus for many nations. The utilization of phase change materials (PCMs) for photothermal energy storage in the medium temperature range holds great potential for various applications, but their conventional forms face several challenges. For instance, the longitudinal thermal conductivity of photothermal PCMs is inadequate for effective heat storage on the photothermal conversion surface, and there is a risk of leakage due to repeated solid-liquid phase transitions.

Recently, Li-ion capacitors (LICs) have drawn tremendous attention due to their high energy/power density along with long cycle life. Nevertheless, the slow kinetics and stability of the involved anodes as bottleneck barriers always result in the modest properties of devices. The exploration of advanced anodes with both high ionic and electronic conductivities as well as structural stability thus becomes more significant for practical applications of LICs.

Optical interferometry plays an important role in the topographical surface measurement and characterization in precision/ultra-precision manufacturing. An appropriate surface reconstruction algorithm is essential in obtaining accurate topography information from the digitized interferograms. However, the performance of a surface reconstruction algorithm in interferometric measurements is influenced by environmental disturbances and system noise.

Article Synopsis
  • Microplastics are a significant global pollutant, but research is hindered by the lack of quick, standardized analysis methods.
  • A new approach using Thermogravimetric Analysis (TGA) combined with Fourier Transform Infrared Spectroscopy (FTIR) allows for the identification and quantification of specific microplastics, such as PVC and PS, by analyzing their unique temperature profiles and infrared absorption spectra.
  • This TGA-FTIR method has been validated in field samples from bivalves, seawater, and soil, indicating it could be useful for broader environmental testing.

Article Synopsis
  • * Results indicate that smaller particles are more effective at enhancing compressibility, with SiC increasing compressibility by up to 100% when its content rises from 0 to 30%, although it negatively impacts thermal conductivity.
  • * Adding Cu particles can improve compressibility slightly and significantly enhance thermal conductivity by about 100% with a 30% increase in Cu content, suggesting that optimal preparation conditions can yield composites that balance low density, high thermal conductivity, and high compressibility for practical applications.
