“…Recently, organic-inorganic PBZ copolymers containing double-decker silsesquioxanes (PBZ-DDSQ) in the main chains were obtained demonstrating good film-forming properties and enhanced surface hydrophobicity in comparison with simple BZ homopolymer. [38] More than that, the PBZ-DDQS copolymers showed good thermal stability and high glass transition temperatures (230-287 °C).…”

The synthesis of composite materials based on various carbon structures and polybenzoxazines (PBZs) gives products with noticeable thermal, electrical, and mechanical properties. The role of different carbon materials is emphasized in terms of the main advantages in both structure and properties. On the other hand, the PBZ features are significant considering the high glass transition temperatures, low flammability, high char yields, and good thermal stability. This review article describes the synthesis, structure, and properties of polybenzoxazine composites based on carbon fibers, carbon nanotubes, graphene, graphene oxide, and other carbonaceous materials. Particular attention is given to the interactions possible to occur between the polybenzoxazine matrix and carbon component.

“…Since the guidance command produced by the PNG lags behind the target manoeuver, and the q   reflects the target manoeuver, it is reasonable to add a differential term (RL) definition, Grümwald Letnikov (GL) definition, and caputo definition. As the proposition of the gamma function and precise methods for solving fractional order equations appear, the fractional calculus has been applied in controller design field 15,16 . Similar to an integer order PID controller, the formulation of fractional order PID controller can be divided into PI λ , PD μ and PI λ D μ (λ and μ represent fractional orders).…”

“…The memory function and stability characteristic make the fractional order PID controller widely apply in the field of aircraft guidance and control 15,16 , such as pitch loop control of a vertical takeoff and landing Unmanned aerial vehicle (UAV) 17 , roll control of a small fixed-wing uAv 18 , perturbed UAV roll control 19 , hypersonic vehicle attitude control 20 , aircraft pitch control 21 , deployment control of a space tether system 22 , position control of a one-DoF flight motion table 23 , and vibration attenuation to airplane wings 24 . The viscosity of the atmosphere interacting with air vehicles has endued aircrafts the aerodynamics similar to the fractional order systems, thus the fractional order PID control theory is appropriate to design the aircraft guidance and control system.…”

Fractional Calculus Guidance Algorithm in a Hypersonic Pursuit-Evasion Game

et al. 2017

<p class="p1">Aiming at intercepting a hypersonic weapon in a hypersonic pursuit-evasion game, this paper presents a fractional calculus guidance algorithm based on a nonlinear proportional and differential guidance law. First, under the premise of without increasing the complexity degree of the guidance system against a hypersonic manoeuvering target, the principle that the differential signal of the line-of-sight rate is more sensitive to the target manoeuver than the line-of-sight rate is employed as the guidelines to design the guidance law. A nonlinear proportional and differential guidance law (NPDG) is designed by using the differential derivative of the line-of-sight rate from a nonlinear tracking differentiator. By using the differential definition of fractional calculus, on the basis of the NPDG, a fractional calculus guidance law (FCG) is proposed. According to relative motions between the interceptor and target, the guidance system stability condition with the FCG is given and quantitative values are also proposed for the parameters of the FCG. Under different target manoeuver conditions and noisy conditions, the interception accuracy and robustness of these two guidance laws are analysed. Numerical experimental results demonstrate that the proposed guidance algorithms effectively reduce the miss distance against target manoeuvers. Compared with the NPDG, a stronger robustness of the FCG is shown under noisy condition.</p>

“…At present, the polymeric prodrugs have attracted considerable attention to achieve low toxicity and potential drug delivery toward cancer cells . Polymer‐drug conjugates in which drug molecules are covalently bound to polymeric systems via biodegradable linkers are promising co‐delivery carriers . They form a stable structure that prolongs the circulation of drugs and delivers drug molecules to specific sites because of the labile linkages between the drugs molecules and the polymers .…”

Recently, polymer drug conjugates (PDCs) have attracted considerable attention in the treatment of cancer. In this work, a simple strategy has been developed to make PDCs of an antitumor alkylating agent, chlorambucil, using a biocompatible disulphide linker. Chlorambucil-based chain transfer agent was used to prepare various homopolymers and block copolymers in a controlled fashion via reversible addition-fragmentation chain transfer polymerization. Chlorambucil conjugated block copolymer, poly(polyethylene glycol monomethyl ether methacrylate)-b-poly(methyl methacrylate), formed nanoaggregates in aqueous solutions, which are characterized by dynamic light scattering and field emission-scanning electron microscopy. Finally, the simplicity of the design is exemplified by performing a release study of chlorambucil under reducing condition by using D,L-dithiothreitol.
