TL;DR: Dipeptide-based delivery carriers through GA-assisted assembly may provide a new alternative for developing precisely controlled nanostructures toward effective antitumor therapy.
Abstract: Self-assembling peptide-based materials are playing an important role in fabricating drug delivery carriers; however, they are often limited by several challenges, such as precise structure modulation, desirable nanoscale size, and sufficient circulation lifetime in the body. To address this issue, herein one type of injectable dipeptide-based nanocarriers with well-modulated size and structure has been developed by adjusting glutaraldehyde (GA)-assisted cationic dipeptide (CDP) assembly. After loading a model photosensitive drug (Ce6) and further decorating CDP nanoparticles (NPs) with heparin polymers (Hep), the desired dipeptide-based NPs are achieved with an average diameter of 100 nm and surface charge of −25 mV, which are favorable for the enhanced permeability and retention effects. Significantly, the dipeptide-based NPs with Ce6 loading have a longer circulation lifetime against opsonization than free Ce6 solution, and subsequently, they achieve the best anticancer efficiency in vivo. They do not ...

TL;DR: A new dynamic controller is developed with two online tuned gains such that the fixed-time leader-following consensus is achieved and it is mathematically proved that the upper bound of the convergence time only depends on system parameters and controller parameters.
Abstract: This article investigates the fixed-time leader-following consensus problem for high-order nonlinear multiagent systems dominated by the lower triangular model with a time-varying gain Based on the fixed-time distributed observer and dynamic gain control approach, a new dynamic controller is developed with two online tuned gains such that the fixed-time leader-following consensus is achieved It is mathematically proved that the upper bound of the convergence time only depends on system parameters and controller parameters, which makes it possible to obtain a prescribed convergence time regardless of the initial conditions Simulation results are given to demonstrate the proposed results

TL;DR: In this paper, a quantitative analysis method of Nb in solution and in precipitates was proposed to quantitatively measure Nb either as solute in solution or in NbC precipitates, which are thought to be effective at pinning grain boundaries.
Abstract: Nb is often considered to be a powerful alloying element for controlling the recrystallization process in microalloyed high strength steels. However, Nb can be presented either as solute in solution, where it is thought to exhibit a strong solute drag effect, or as NbC precipitates, which are thought to be effective at pinning grain boundaries. Therefore, it is very important to quantitatively measure Nb in solution or in NbC precipitates. A quantitative analysis method of Nb in solution and in precipitates was proposed. The test procedure involved chemical dissolution, filtration and inductively coupled plasma atomic emission spectroscopic (ICP-AES) analysis. The amount of Nb in solution in Nb-microallyed steels under different treatment conditions was evaluated. The results show that the niobium and carbon contents in steels have a great effect on niobium dissolution kinetics. The solute Nb is more effective to retard dynamic recrystallization, while the NbC precipitates are more effective to inhibit static recrystallization. The results may help to comprehend effect of Nb in steels, and provide some guides in the design of new high strength Nb-bearing steels.
