Adaptive optimal ℓ∞‐induced robust stabilization of minimum phase SISO plant under bounded disturbance and coprime factor perturbations
Authors: Sokolov Victor F. 
Published: January 2024

AbstractThis paper addresses the problem of optimal robust stabilization of a discrete‐time minimum‐phase plant in the framework of robust control theory in the setup and under poor a priori information. Coefficients of the transfer function of the plant nominal model with stable zeros are unknown and belong to a known bounded polyhedron in the space of coefficients. The gains of coprime factor perturbations of the plant and the upper bound of external disturbance are also unknown. The problem under consideration is to design adaptive controller that minimizes, with the prescribed accuracy, the worst‐case asymptotic upper bound of the output. Solution of the problem is based on set‐membership estimation of unknown parameters and treating the control criterion as the identification criterion. A hard nonconvex problem of on‐line computation of optimal estimates is reduced, under additional nonrestrictive assumption, to a linear‐fractional programming via a nonlinear transformation of estimated parameters. Despite the non‐identifiability of the unknown parameters, the proposed adaptive controller guarantees, with the prescribed accuracy, the same optimal asymptotic upper bound of the output of adaptive system as the optimal controller for the plant with known parameters. In addition to the optimality of adaptive control, the proposed solution provides on‐line verification/validation of current estimates and a priori assumptions.

Authors: Ijaz Baig Maria , Yadegaridehkordi Elaheh 
Published: January 2024

AbstractThis study seeks to identify the determinants of economic and environmental sustainability through green supply chain management (GSCM) and explore the moderating role of blockchain adoption in the relationships between GSCM and economic and environmental sustainability. The theoretical model was developed based on a natural‐resource‐based view and stakeholder theory. The structural equation modeling‐fuzzy set qualitative comparative analysis (SEM‐fsQCA) was used to analyze the data, which were gathered from 179 organizations in Malaysia. The SEM results showed that green technology, green marketing, and customer pressure are the factors that affect GSCM and enhance economic and environmental sustainability. The fsQCA findings supported SEM results by indicating that a combination of customer pressure, green technology, green marketing, and GSCM was necessary to achieve the highest level of an organization's economic and environmental sustainability. Moreover, the assessment of the moderating effect highlighted that blockchain adoption strengthened the association between GSCM and organization economic and environmental sustainability. The findings of this study help managers and organizations understand how blockchain adoption can enhance economic and environmental sustainability.

AbstractIn this study, a novel synthesized pearlite/ferrite/guar gum (PFG) hydrogel was evaluated. Theoretical studies using molecular dynamics simulation through the Forcite module in Material Studio 2017 showed crystal violet (CV) and naproxen (NAP) dye drug adsorption relative to other dyes and drugs. One of the best ways to remove pollutants is adsorption. With the absorption method, harmful contaminants such as CV and NAP can be removed from the water and wastewater cycle. Morphology and functional groups of natural compounds and synthesized materials were determined using FT‐IR, XRD, TGA, VSM, EDX, BET and FE‐SEM analysis. The potential of the hydrogel to effectively remove CV and NAP from a saturated solution was studied experimentally based on the efficiency of adsorbent dose, pH and temperature. The composition follows the PSO kinetically and the Langmuir model in terms of the isotherm. The maximum absorption capacity of CV (244.40 mg/g) and NAP (180.15 mg/g) in hydrogel was investigated. According to the antibacterial activity test, the synthesized hydrogel had no antibacterial properties.

AbstractIn this paper, the encapsulating effect of single molecule of zinc porphyrin (Zn−P) inside semiconducting single walled carbon nanotubes (NT17) on the stability and optoelectronic properties of organic solar cells is investigated, assuming that this nano‐hybrid system will serve as the active layer in solar cell device. Making use of density functional theory (DFT), we looked at the optoelectronic characteristics of the isolated Zn−P molecules as well as two different configurations of the hybrid system that has a single Zn−P molecule inserted into NT17 (Zn−P@NT17 and Zn−P2@NT17). The addition of a zinc atom at the core of a porphyrin molecule results in the emergence of novel electronic and chemical characteristics, leading to distinct behavior compared to a free‐base porphyrin. These distinctions hold substantial implications for a range of applications, encompassing catalysis, sensing, and energy conversion processes. According to the study's outcomes, a charge transfer (CT) between the Zn−P molecules and the NT17 nanotube caused the structure to remain stable, and assuming to the electronic and optical computations the CT in Zn−P@NT17 hybrid nanosystems has been identified, along with its orientation. The results show that type II heterojunctions on filled semiconducting carbon nanotubes are likely to make them a viable choice for charge and light transport in the active layer, which can help create filled NT‐based OSCs that are extremely efficient.

AbstractIntermolecular interactions and molecular configurations are of great significance for the formation of liquid crystals. During this study, a series of isomer compounds with biphenyl esters as rigid cores were synthesized, and their mesomorphic properties and thermal stability were investigated. Based on the same rigid core, compounds heptyl 4′‐methoxy‐[1,1′‐biphenyl]‐4‐carboxylate (1OBE7), propyl 4′‐(pentyloxy)‐[1,1′‐biphenyl]‐4‐carboxylate (5OBE3), ethyl 4′‐(hexyloxy)‐[1,1′‐biphenyl]‐4‐carboxylate (6OBE2) and methyl 4′‐(heptyloxy)‐[1,1′‐biphenyl]‐4‐carboxylate (7OBE1) have no mesophase, while compounds hexyl 4′‐ethoxy‐[1,1′‐biphenyl]‐4‐carboxylate (2OBE6), pentyl 4′‐propoxy‐[1,1′‐biphenyl]‐4‐carboxylate (3OBE5) and butyl 4′‐butoxy‐[1,1′‐biphenyl]‐4‐carboxylate (4OBE4) have multiple smectic mesophases, whereas the production of the smectic mesophase is due to the microphase separation between aromatic cores and the alkyl chains. Compound 3OBE5 exhibiting good thermal stability (The value of T5% is 258.3 °C). In addition, with the right shift of the functional group position, compound 4OBE4 formed the widest smectic mesophase. The results show that the mesophase properties and thermal stability of liquid crystals are related to the position of the functional group.

AbstractSolar‐driven hydrogen (H2) evolution combined with synchronously selective oxidation for fine chemicals production is of great significance in energy and synthetic chemistry. Herein, ultrafine Pd nanoparticles‐encapsulated MIL‐100(Fe) (Pd‐MOF‐Fe) nanocomposites are synthesized through double‐solvent impregnation integrated with photo‐reduction method. Integrating MOF‐based catalysis and Pd‐based catalysis, the Pd‐MOF‐Fe can serve as multifunctional catalyst for photoinduced alcohol dehydrogenation reaction. Optimal generation rates of H2 (3.61 mmol g−1 h−1) and benzaldehyde (3.40 mmol g−1 h−1) are gained over Pd‐MOF‐Fe, ca. 4.1 times that of the Pd/MOF‐Fe, in which Pd crystals with size ranging from 3 to 6 nm are immobilized on the intersurface of MOFs. Besides, controlled experiments reveal the pivotal role of the opened FeO6 nodes of MIL‐100(Fe) as Lewis acid sites toward alcohol activation. This work provides a controllable approach for metal nanoparticle immobilization. Furthermore, considering the diversified MOF structures, this study also highlights the infinite possibility of metal nanoparticle/MOFs as multifunctional platform for solar energy conversion and chemicals production.

Published: January 2024

AbstractProcalcitonin (PCT), as a disease biomarker, is of significant importance in the early diagnosis of sepsis. To this end, we developed a surface‐enhanced Raman scattering (SERS) magnetic immunoassay that utilizes the double‐antibody sandwich principle for the rapid and quantitative detection of PCT. The core‐shell nanoparticles which contain Raman reporters (Au@XP013@AgNPs) are paired with tracer antibodies and coupled with biotin‐coupled capture antibodies, thereby forming a sandwich structure. This structure is readily captured by streptavidin (SA) magnetic beads and can be enriched by an external magnetic field. Raman spectroscopy was utilized to carry out detection, with PCT concentration ranging from 0–20 ng/mL. The Raman signal displays an excellent linear correlation with PCT concentration, and the LOD is 0.012 ng/mL, implying remarkable sensitivity. Efficiency of separation can be significantly enhanced by utilizing an external magnetic field, leading to a detection time of approximately 15 minutes. Thus providing a new technological reference for the clinical detection of sepsis biomarkers.

AbstractA combination of reagents using I2 and DMSO has been established for the selective transformation of unactivated alkenes into iodohydrins and β‐iodoethers. The developed approach was served by the dual roles of DMSO as an oxidant as well as a hydroxylating agent under different solvent systems at 85 °C. The developed method holds an operational simplicity and is consistent with wide range of substituted alkenes to deliver iodohydrins and β‐iodoethers in yields up to 86 %. The formation of iodohydrins are selective in MeCN as solvent and the course of the reaction was examined by GC‐MS studies and DFT method.

Published: January 2024

AbstractIn this study, a hybrid conjugate of formononetin (FMN) and vitamin E (VESylated‐FMN) was synthesized through succinic acid linker and investigated for its synergistic effect in diabetes. The conjugate was characterized through Ultra Performance Liquid Chromatography – Mass Spectrometry (UPLC‐MS), High‐Resolution Mass Spectrometry (HRMS), Nuclear Magnetic Resonance (NMR), and Differential Scanning Calorimetry (DSC). The ability of VESylated‐FMN to promote adipogenesis and ameliorate insulin resistance brought on by oxidative stress was evaluated in differentiated preadipocytes. Interestingly, VESylated‐FMN promoted intracellular glucose absorption, which in turn increased lipid and triglyceride accumulation and thereby encouraged adipogenesis. VESylated‐FMN attenuated oxidative stress and promoted cell survival by reducing reactive oxygen species (ROS) generation and reversing apoptosis. Additionally, VESylated‐FMN improved insulin sensitization by upregulating the gene and protein expression of insulin‐sensitizing markers. Overall, FMN in conjugation with vitamin E can effectively augment prior insulin sensitivity by reducing oxidative stress for efficient glycemic control in hyperglycemia.

Published: January 2024

AbstractIn this study, a series of derivatives of pyrazole hybrid structures containing carbonitrile and substituted thiazole moiety were designed to search for selective COX‐2 inhibition. The designed target structures were synthesized with easy, practical, and efficient procedures. COX‐1/2 inhibition and cytotoxic effects of the synthesized compounds were evaluated in NIH/3T3 and MDA‐MD‐231 cell lines for inhibition concentration and selectivity index. The results showed that the compounds have an inhibitory effect with higher selectivity towards COX‐2 overall in both cell lines and moderate antiproliferative activity by targeting the breast cancer cell line MDA‐MB‐231. Among the 19 compounds synthesized (19 a–t), especially compound 19 m was found to be highly effective with COX‐2 inhibition of 5.63 μM in the NIH/3T3 cell line and 4.12 μM in the MDA‐MB‐231 cell line. Moreover, molecular docking studies showed that the compounds indeed exhibited higher affinity for the COX‐2 active site. The theoretical ADMET properties of the presented compounds were calculated, and the results showed that the compounds may have a more favorable pharmacokinetic effect profile than the selective COX‐2 inhibitor Celecoxib, thus promising COX‐2 inhibitor drug candidates for the future.

Published: January 2024

AbstractIn order to avoid structural instability caused by the hydrolysis of spiropyran unit during responsive process, a new spiropyran monomer named as SPA was prepared by grafting carbamate functional groups to side chain of spiropyran frame. With SPA, 2‐(2‐(2‐methoxyethoxy) ethoxy) ethyl methacrylate (MEO3MA) and 2‐(diethylamino) ethyl methacrylate (DEAEMA) as the organic monomers, a triple responsive copolymer, P(SPA‐co‐MEO3MA‐co‐DEAEMA) abbreviated as PSOD, was obtained by one‐pot random copolymerization. The chemical structure, responsive behaviors and self‐assembly of the resulting copolymer were studied by a series of technical methods. With 5‐Fluoro‐2′‐deoxyuridin (FUDR) as the model anti‐cancer drug, the loading and controlled releasing behaviors of the copolymer micelles were systematically explored. Also, the cytotoxicity test and fluorescence imaging of PSOD copolymer were performed with human breast cancer cell line (MCF‐7) as the experimental subject. The results showed that the copolymer micelles had controllable drug releasing performance in complex combined stimuli conditions, and the releasing process could be well described by Korsmeyer‐Peppas model. The cytotoxicity of PSOD was proved to be relatively low, which laid a foundation for the subsequent in‐vivo drug releasing. Triple responsive performance of the copolymer micelles might provide a new inspiration for the future study of drug‐controlled releasing system.

Published: January 2024

AbstractRheumatoid arthritis (RA) progression involves multiple cell types, and sequential drug action on target cells is necessary for RA treatment. Nanocarriers are widely used for RA treatment; however, the targeted delivery and on‐demand release of multiple drugs remains challenging. Therefore, in this study, a dual‐sensitive polymer is developed using chondroitin sulfate (CS) for the co‐delivery of the cartilage repair agent, glucosamine (GlcN), and anti‐inflammatory drug, tofacitinib (Tof). In the joint cavity, acidic pH facilitates the cleavage of GlcN from CS polymer to repair the cartilage damage. Subsequently, macrophage uptake via CS–CD44 binding and intracellular reactive oxygen species (ROS) mediate conversion of (methylsulfanyl)propylamine to a hydrophilic segment jointly triggered rapid Tof/GlcN release via micelle disassembly. The combined effects of Tof, GlcN, and ROS depletion promote the M1‐to‐M2 polarization shift to attenuate inflammation. The synergistic effects of these agents against RA are confirmed in vitro and in vivo. Overall, the dual pH/ROS‐sensitive CS nanoplatform simultaneously delivers GlcN and Tof, providing a multifunctional approach for RA treatment with synergistic drug effects.
In Situ Raman Study of Surface Reconstruction of FeOOH/Ni3S2 Oxygen Evolution Reaction Electrocatalysts

Published: January 2024

AbstractConstruction of heterojunctions is an effective strategy to enhanced electrocatalytic oxygen evolution reaction (OER), but the structural evolution of the active phases and synergistic mechanism still lack in‐depth understanding. Here, an FeOOH/Ni3S2 heterostructure supported on nickel foam (NF) through a two‐step hydrothermal‐chemical etching method is reported. In situ Raman spectroscopy study of the surface reconstruction behaviors of FeOOH/Ni3S2/NF indicates that Ni3S2 can be rapidly converted to NiOOH, accompanied by the phase transition from α‐FeOOH to β‐FeOOH during the OER process. Importantly, a deep analysis of Ni─O bond reveals that the phase transition of FeOOH can regulate the lattice disorder of NiOOH for improved catalytic activity. Density functional theory (DFT) calculations further confirm that NiOOH/FeOOH heterostructure possess strengthened adsorption for O‐containing intermediates, as well as lower energy barrier toward the OER. As a result, FeOOH/Ni3S2/NF exhibits promising OER activity and stability in alkaline conditions, requiring an overpotential of 268 mV @ 100 mA cm−2 and long‐term stability over 200 h at a current density of 200 mA cm−2. This work provides a new perspective for understanding the synergistic mechanism of heterogeneous electrocatalysts during the OER process.
The Role of Digital Building Logbooks for a Circular Built Environment
Authors: Gonçalves Joana Dos Santos , Lam Wai Chung , Ritzen Michiel 
Published: January 2024

AbstractDigital building logbooks (DBLs) are digital repositories of building-related data gathered throughout the full life cycle of a building. DBLs help increase transparency and access to information during the design, construction, operation, and end-of-life phase of a building. They thereby facilitate an efficient and cost-effective transition to a zero energy and circular built environment. DBLs could slow down resource loops by extending the service life of buildings through better coordination of maintenance and repair and close resource loops by promoting adaptability and reuse of the whole building and/or its components with multi-cycle approaches. This chapter analyses examples of DBLs developed in five countries to show that they are useful tools at different life stages of the building and for different stakeholders (homeowners, property managers, or building professionals). Challenges for establishing DBLs as a central tool for a circular built environment lie in improving the user experience and ease of implementation; enhancing interoperability; and effectively collecting, managing, and transforming data into actionable information for the management, maintenance, and reuse at building and district levels.
From Data Templates to Material Passports and Digital Product Passports

Published: January 2024

AbstractLack of data and difficulty in tracking materials and elements are two major obstacles in the construction industry that hinder the realisation of a circular economy. Data templates, material passports (MPs), and digital product passports (DPPs) are passport instruments that provide valuable information about buildings. Data templates deliver digital standardised data structures for MPs (digital data sets describing building characteristics of, e.g. elements) and DPPs (cross-sectoral passports developed by the European Union to collect product data for sustainability).MPs, which are associated with the built environment, help urban miners and building owners assess the value and reuse potential of building materials and elements. Several initiatives, such as Madaster, Concular, and Platform CB’23, have produced data templates and MPs for new and existing buildings. Challenges to their use include the lack of standardisation of data templates and MPs and difficulties in collecting and tracing data needed to create and maintain MPs through a building’s life cycle. Standardisation would foster the implementation of passports, but aligning existing concepts and identifying overlaps remains a present challenge. Future research and practice suggest that using geographic information systems, laser scanning, and computer vision will help deploy MPs more effectively in practice.

Published: January 2024

AbstractThe human behavior of listening to and playing music has existed since prehistoric times. Music is often valued for the emotions it generates, and listening to music can boost mood and increase well-being. In this chapter, we dive into the “neuroaesthetics of music” in a deeper sense and explore why music is so appealing to us (aesthetically speaking) and what is happening in the neuronal levels of our brain when we listen to music.
Unit 2 Lesson: Portraits as Faces
Authors: Hodne Lasse 
Published: January 2024

AbstractPortraits have been a part of human civilization for thousands of years. According to the famous Roman historian and naturalist, Pliny the Elder (AD 23/24–79), the first painting ever made, was a portrait. It was presumably invented by the daughter of a man called Butades, a potter from Sicyon in Greece. To preserve the memory of her beloved who was going away for a while, she decided to trace the profile of his head from the shadow cast on a wall.
