Identification of system mode parameters using response measurement only

Huo Bingyong and Yi Weijian

Strategic Study of CAE 2015, Volume 17, Issue 1,   Pages 151-160

Abstract:

With the broadest application and development of modal analysis method， the demands such as less restrictive conditions and to increase the reliability of an analysis have been increased for more convenience in engineering applications. This paper presents a new modal analysis method without input data and any analytical models. Harmonic parameters of a point response can be extracted by spectrum analysis using the measurements obtained from structural testing. Preliminary results calculated by discrete deconvolution techniques are further modified by the frequency domain space curve fitting method. Modal parameters of system just come from a combination of these corrected results. The performed analysis and validation of real data indicate that the approach is feasible for engineering. Therefore， this paper provides the effective estimation scheme of modal parameters for experiment research on the system dynamic performance.

Synthesis and characterization of biocompatible polyurethanes for controlled release of hydrophobic and

Juichen YANG,Hong CHEN,Yuan YUAN,Debanjan SARKAR,Jie ZHENG

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 4,   Pages 498-510 doi: 10.1007/s11705-014-1451-9

Abstract: Design of biocompatible and biodegradable polymer systems for sustained and controlled release of bioactive agents is critical for numerous biomedical applications. Here, we designed, synthesized, and characterized four polyurethane carrier systems for controlled release of model drugs. These polyurethanes are biocompatible and biodegradable because they consist of biocompatible poly(ethylene glycol) or poly(caprolactone diol) as soft segment, linear aliphatic hexamethylene diisocyanate or symmetrical aliphatic cyclic dicyclohexylmethane-4,4′-diisocyanate as hard segment, and biodegradable urethane linkage. They were characterized with Fourier transform infrared spectroscopy, atomic force microscope, and differential scanning calorimetry, whereas their degradation behaviors were investigated in both phosphate buffered saline and enzymatic solutions. By tuning polyurethane segments, different release profiles of hydrophobic and hydrophilic drugs were obtained in the absence and presence of enzymes. Such difference in release profiles was attributed to a complex interplay among structure, hydrophobicity, and degradability of polyurethanes, the size and hydrophobicity of drugs, and drug-polymer interactions. Different drug-polyurethane combinations modulated the distribution and location of the drugs in polymer matrix, thus inducing different drug release mechanisms. Our results highlight an important role of segmental structure of the polyurethane as an engineering tool to control drug release.

Phase transition regulation and caloric effect

Frontiers in Energy 2023, Volume 17, Issue 4,   Pages 463-477 doi: 10.1007/s11708-023-0860-1

Abstract: Solid state refrigeration based on caloric effect is regarded as a potential candidate for replacing vapor-compression refrigeration. Numerous methods have been proposed to optimize the refrigeration properties of caloric materials, of which single field tuning as a relatively simple way has been systemically studied. However, single field tuning with few tunable parameters usually obtains an excellent performance in one specific aspect at the cost of worsening the performance in other aspects, like attaining a large caloric effect with narrowing the transition temperature range and introducing hysteresis. Because of the shortcomings of the caloric effect driven by a single field, multifield tuning on multicaloric materials that have a coupling between different ferro-orders came into view. This review mainly focuses on recent studies that apply this method to improve the cooling performance of materials, consisting of enlarging caloric effects, reducing hysteresis losses, adjusting transition temperatures, and widening transition temperature spans, which indicate that further progress can be made in the application of this method. Furthermore, research on the sign of lattice and spin contributions to the magnetocaloric effect found new phonon evolution mechanisms, calling for more attention on multicaloric effects. Other progress including improving cyclability of FeRh alloys by introducing second phases and realizing a large reversible barocaloric effect by hybridizing carbon chains and inorganic groups is described in brief.
