Summary: The study found that under DPPC lubrication, PEEK exhibited better wear resistance than UHMWPE, and under high load and low frequency conditions, the friction coefficient of Si3N4/Chirulen(R) 1020 XPE was low. Additionally, the tribological performance of Si3N4 was superior to Al2O3 due to the formation of a protective SiO2 film on its surface in water.

Summary: Steady-state emission spectroscopy, fluorescence anisotropy, and DSC methods were used to characterize the interaction of the newly synthesized 1-carba-alpha-tocopherol (CT) with a 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) membrane. Results showed that even low concentrations of CT can perturb the DPPC structure significantly, leading to the formation of new phases and disruption of the ordered structure. Increasing CT concentrations induced further changes in the DPPC structure, ultimately causing melting at lower temperatures and disruption of the membrane.

Summary: Global demand for transportation fuels is expected to increase by 40% by 2040, with biomass-derived fuels playing a crucial role in replacing fossil fuels and reducing greenhouse gas emissions. Thermochemical conversion technologies are promising for biofuel production, but face challenges such as the thermal instability of intermediate products like bio-oil. Recovery and fractionation strategies can maximize process yields and add value, while physicochemical treatments offer mild operating conditions and potential for integrated solutions in conjunction with other treatments.

Summary: In this study, crocin was used to induce the M1 phenotype in mouse tumor macrophages. A targeted liposomal formulation with m2 peptide was prepared to deliver crocin to M2 macrophages. The results showed that the M2 peptide-modified liposome had improved uptake by macrophages and induced the M1 phenotype through an IL6-independent pathway, leading to anti-tumor effects. The study suggests the potential of using m2 peptide-targeted liposomal formulations for enhanced delivery of crocin in tumor therapy.

Summary: In this study, a lysosome-targeting buffering fluorogenic probe (Lyso-BFP) was designed and synthesized, demonstrating excellent photostability, pH specificity, and responsiveness to lysosomal acidification in living cells. The performance of Lyso-BFP in pH sensing was attributed to the inhibition of the photo-induced electron transfer process. Lyso-BFP allowed for wash-free imaging and long-term real-time monitoring of lysosome pH changes based on its off-on fluorescence behavior and buffer strategy.

Summary: This study presents a method to fabricate independently functioning microneedle (MN) electrodes with narrow intervals for high precision electrochemical sensing. The optimized mixture of photocurable polymer and single-wall carbon nanotubes was used to mold single composite MNs, which were then attached to pre-patterned electrodes. Plasma etching and electropolymerization were performed to enhance the electrochemical activity, and Prussian blue and glucose oxidase were electrodeposited on the MNs for glucose detection. The MN electrodes showed good sensitivity and linearity, and the feasibility of glucose detection was demonstrated in an in vivo mouse study.
