Published: June 2018

AbstractLow compressive strength of aramid fiber is one of the major obstacles for its application in advanced composite materials. In this study, poly‐(benzimidazole‐terephthalamide) (PABI) fibers are fabricated by solid‐phase cross‐linking of corresponding oligomers end‐capped with norbornene anhydride (NA). Concentration of the spinning solution increases and apparent viscosity is reduced significantly through this method, which improves its processability. Reactivity and thermal stability of the NA group are measured by in situ Fourier transform infrared (FTIR) and thermogravimetric analysis and it shows high reactivity at 360 °C and adequate thermal stability under 400 °C. Results of solubility test and dynamic mechanical analysis indicate cross‐linking degree increases with decrease of molecular weight of the corresponding oligomer. Results of both 2D wide angle X‐ray diffraction and polarized FTIR illustrate orientation will be affected by cross‐linking and it decreases with the increase of cross‐linking degree. PABI fibers fabricated through this method can maintain outstanding mechanical properties and compressive strength is improved by 67% at most. Interestingly, interfacial shear strength of PABI fibers is improved by nearly 20% and damage between skin–core layers after debonding of fiber and resin is not observed.

AbstractIn the present work, gelatin type B is modified with highly reactive norbornene functionalities (Gel‐NB) following a one‐pot synthesis approach to enable subsequent thiol–ene photo‐click crosslinking. The modification strategy displays close control over the amount of introduced functionalities. Additionally, Gel‐NB exhibits considerably improved processing capabilities in terms of two‐photon polymerization when benchmarked to earlier‐reported crosslinkable gelatin derivatives (e.g., gelatin‐methacrylamide (Gel‐MOD) and gelatin‐methacrylamide‐aminoethylmethacrylate (Gel‐MOD‐AEMA)). The improvement is especially apparent in terms of minimally required laser power (20 mW vs ≥60 mW (Gel‐MOD) vs ≥40 mW (Gel‐MOD‐AEMA) at 100 mm s−1 scan speed) and processable concentration range (≥5 w/v% vs ≥10 w/v% (Gel‐MOD/Gel‐MOD‐AEMA)). Furthermore, the proposed functionalization scheme maintains the excellent biocompatibility and cell interactivity of gelatin. Additionally, the norbornene functionalities have potential for straightforward postprocessing “thiol–ene” surface grafting of active molecules. As a consequence, a very promising material toward tissue engineering applications and more specifically, biofabrication, is presented.
Polystyrene‐based anion exchange membranes via click chemistry: improved properties and AEM performance

Published: June 2018

ABSTRACTPolystyrene‐based anion exchange membranes (AEMs) have been fabricated using in situ click chemistry between azide and alkyne moieties introduced as side groups on functionalized polymers. The membrane properties such as water uptake, swelling ratio and conductivity were affected by the number of cations and the degree of crosslinking. The membranes containing a larger amount of trimethylammonium cationic groups (i.e. higher ion exchange capacity) showed high hydroxide conductivity when immersed in KOH solution, exhibiting a peak in conductivity (156 mS cm−1) in 3 mol L–1 KOH solution. A higher degree of crosslinking tended to decrease conductivity. These membranes demonstrated relatively good stability in 8 mol L–1 KOH at 60 °C and maintained 33%–62% of initial conductivity after 49 days with most of the loss in conductivity occurring in early stages of the test. In an alkaline fuel cell, the areal specific resistance was constant indicating good stability of the membranes. The observed peak power density (157 mW cm−2) was comparable to that of other AEM‐based fuel cells reported. © 2018 Society of Chemical Industry
Perovskite/c‐Si tandem solar cells with realistic inverted architecture: Achieving high efficiency by optical optimization
Authors: Ba Lixiang , Liu Hong , Shen Wenzhong 
Published: June 2018

AbstractMany theoretical analyses for perovskite/c‐Si monolithic tandem solar cells (TSCs) have shown optical optimization and high efficiency limits, but they use many idealized assumptions and draw some unpractical conclusions for experiments. In this work, we have introduced a composite method combining the finite difference time domain and light path analysis for the first time. By using this method, we have systematically calculated perovskite/c‐Si monolithic TSCs with inverted architecture based on realistic solar cell parameters. Theoretical results have demonstrated very good match of the experimental external quantum efficiencies of both subcells. More importantly, from optical and electrical point of view, we have analyzed current losses of such TSCs and proposed detailed optimization for achieving high efficiency. Finally, we have presented improved configuration of perovskite/c‐Si monolithic TSCs with addition of pyramids structure in front surface, which can effectively increase the tandem cell efficiency to 29.05%. This work can be served as a practical guidance for the realization of high‐efficient perovskite/c‐Si monolithic TSCs.

AbstractThe dynamic changes that take place along the phases of microbial growth (lag, exponential, stationary, and death) have been widely studied in bacteria at the molecular and cellular levels, but little is known for archaea. In this study, a high‐throughput approach was used to analyze and compare the proteomes of two haloarchaea during exponential and stationary growth: the neutrophilic Haloferax volcanii and the alkaliphilic Natrialba magadii. Almost 2000 proteins were identified in each species (≈50% of the predicted proteome). Among them, 532 and 432 were found to be differential between growth phases in H. volcanii and N. magadii, respectively. Changes upon entrance into stationary phase included an overall increase in proteins involved in the transport of small molecules and ions, stress response, and fatty acid catabolism. Proteins related to genetic processes and cell division showed a notorious decrease in amount. The data reported in this study not only contributes to our understanding of the exponential–stationary growth phase transition in extremophilic archaea but also provides the first comprehensive analysis of the proteome composition of N. magadii. The MS proteomics data have been deposited in the ProteomeXchange Consortium with the dataset identifier JPST000395.

Published: June 2018

AbstractInspired by natural dewetting phenomena, such as the coffee‐ring effect, researchers are developing strategies for the controlled assembly of colloidal particles into functional nanoparticle conglomerates. Colloidal assembly techniques are regarded as green methods as they reduce or eliminate the use or generation of hazardous substances involved in other manufacturing modalities. This review discusses several recent developments in interface colloidal deposition for preparing nanoparticle wires and integrated nanoparticle wire arrays. Moreover, this review covers real applications of these structures for electric detection of chemical and biological molecules among other functions.
Examining the survival benefit of radiation therapy on leptomeningeal carcinomatosis and identifying factors associated with survival benefit of whole‐brain radiation therapy
Authors: Kim Jae 
Published: June 2018

AbstractToday, there are no conclusive data on the survival benefit from radiation therapy for leptomeningeal carcinomatosis (LMC) patients. The purpose of this article is mainly two folds: first, to report the survival benefit of radiation therapy (RT) in LMC patients with breast or lung as primary cancer and second, to identify the factors of LMC patients that had survival benefit from whole brain radiation therapy (WBRT).Systematic literature review was performed. Search terms included ‘Leptomeningeal’, ‘prognostic factors’ and ‘lung’ or ‘breast’. Literatures were included if patient profile was reported. Specifically, age, median survival, diagnosis time line, type of cancer, received treatments, performance score, and systemic disease were sought after. Literature were excluded if they were a) case reports, b) written in language other than English, or c) not including patient profile.For LMC patients with primary breast cancer, 7 studies were found since 1991 that met searching criteria. Factors which would allow breast cancer‐caused LMC patients to benefit from WBRT with survival are identified with statistical significance. They include Karnofsky (KPS) >60, Intrathecal (IT) chemotherapy, systemic therapy, hormonal receptor status and severity of systemic disease. Patients who met aforementioned criteria and received WBRT had longer median survival (17 weeks vs 11.9 weeks, P = 0.015). Similarly, 10 studies were found that met searching criteria for non‐small cell lung cancer (NSCLC) caused LMC. Beneficial factors for NSCLC‐caused LMC are identified. They include IT chemotherapy, KPS > 60, and epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) treatment. Patient who met these criteria had longer median survival when received WBRT (17.6 weeks vs 12.2 weeks, p = 0.0412).

AbstractBACKGROUNDEntomopathogenic Beauveria bassiana has been used as a biocontrol agent for insect pests, but its effect at the molecular level on the hosts has not been studied in detail. Herein, we performed transcriptome analysis of bean bug, Riptortus pedestris (Hemiptera: Alydidae) in response to infection with a highly virulent strain of B. bassiana JEF‐007 (Bb JEF‐007).RESULTSBased on RNA‐seq data from R. pedestris infected with Bb JEF‐007 compared with non‐infected bean bugs, infection was assumed to strongly activate (i) the energy production pathway by expressing dehydrogenases, (ii) metabolic pathways by expressing secreted proteins, GTPase, MBF2 transcription factor family, pigment‐dispersing factor, antioxidants, and cuticle proteins, and (iii) the immune response pathway by expressing serine‐threonine kinase in Toll pathway of bean bug.CONCLUSIONWe have established the platform for functional studies of the genes required for an immune response against entomopathogenic fungi like B. bassiana in the bean bug, R. pedestris. Moreover, this study also paves the way for genetic modification of B. bassiana to combat with the defense mechanism of R. pedestris. © 2018 Society of Chemical Industry
Observer‐based attack‐resilient control for linear systems against FDI attacks on communication links from controller to actuators
Authors: Xie Chun‐Hua , Yang Guang‐Hong 
Published: June 2018

SummaryFor the adversarial attacks on the communication links from the controller to the actuators, most of the existing attack‐resilient control results focus on denial‐of‐service attacks. Unlike the existing results, this paper studies the observer‐based attack‐resilient control problem for linear systems with false data injection attacks and process disturbances. Due to limited resources, the malicious attacker is assumed to only manipulate a certain number of communication links from the controller to the actuators. A novel control architecture is proposed, which consists of an attack‐resilient state observer, a controller gain scheme, and a supervisory switching strategy. The observer is developed based on the maximin strategy, and state estimation will be used to construct the controller. The switching strategy is designed to pick an appropriate controller gain and prevent the attack signals from entering the plant automatically. It is shown that the closed‐loop system is stable with an attack‐resilient performance. Finally, to verify the effectiveness of the proposed controller, simulation results on a linearized reduced‐order aircraft system and an IEEE six‐bus power system are provided.
Global output‐feedback stabilization for stochastic nonlinear systems: A double‐domination approach
Authors: Sun Zong‐Yao , Shao Yu , Chen Chih‐Chiang , Meng Qinghua 
Published: June 2018

SummaryThis paper is concerned with global stabilization via output feedback for a class of stochastic nonlinear systems with time‐varying continuous output function. Under linear growth conditions, a new double‐domination method is proposed for the first time to construct an output‐feedback stabilizing controller. Different from the related results, the design of the observer is performed without using the information on the output function and nonlinearities. This paper also provides a viewpoint at the feedback stabilization to eliminate the continuous measurement error originating from inaccurate detection of system state. A simulation example is presented to demonstrate the effectiveness of control strategy.

In this context, intrinsically conducting polymers (ICPs) have gained enormous interest in the recent past due to their myriad applications in the field of textile specifically because of their tunable conductivity, lightweight, ease of coating etc. Numerous research studies have been focused to develop electromagnetic (EM) shielding fabric using ICPs and various functional conducting, magnetic and dielectric nanoparticles. The objective of this review article is to highlight the state‐of‐the‐art literature and recent developments in this field involving surface modification of textile fabrics using physical/chemical methods targeted towards EM shielding application. Furthermore, this review also provides useful insight in the shielding mechanism and diverse processes to design and develop smart EM shielded flexible fabrics as protective textiles.
Nanocrystals@Hollow Mesoporous Silica Reverse‐Bumpy‐Ball Structure Nanoreactors by a Versatile Microemulsion‐Templated Approach

Published: June 2018

AbstractReverse‐bumpy‐ball structure (RBBS) nanoreactors represent near‐ideal architectures for optimizing the performance of nanoparticle catalysts. Traditionally, RBBSs have been synthesized using laborious hard‐template methods. Herein, a novel and versatile synthetic strategy toward RBBS nanoreactors is developed by introducing high‐boiling‐point organics into a classical emulsion‐based nanocluster self‐assembly synthesis. This facile approach eliminates the need for a hard template and allows encapsulation of anisotropic nanoparticles in hollow nanoreactors. An RBBS nanoreactor containing Pt‐γ‐Fe2O3 dimers synthesized by this new approach demonstrates outstanding catalytic performance for the reduction of 4‐nitrophenol with H2. The same strategy can easily be adapted for the synthesis of RBBS nanoreactors for other applications including catalysis, high‐performance batteries, drug delivery, sensors, and antimicrobials.

Published: June 2018

AbstractInnovative zukunftsorientierte Konstruktionslösungen im Brückenbau zielen vermehrt auf instandhaltungsarme Strukturen ab, deren Nutzung und überführten Verkehrswege nur in geringem Maße durch Sanierungs‐ und Instandhaltungsarbeiten beeinträchtigt werden. Im Rahmen des FOSTA‐AiF‐Forschungsprojektes „Ganzheitliche Bewertung von Stahl‐ und Verbundeisenbahnbrücken nach Kriterien der Nachhaltigkeit” (P978) wurden deshalb gezielte Untersuchungen zur Optimierung von verschiedenen Eisenbahnbrückentypen an einzelnen Konstruktionsdetails und Konstruktionsvarianten durchgeführt. Zur Erfassung der Auswirkungen dieser optimierten Lösungen auf den Lebenszyklus der Brücke wurden auf Grundlage von Nachhaltigkeitsanalysen die herkömmlichen und verbesserten Konstruktionen miteinander verglichen. Dieser Beitrag befasst sich mit der Bewertung der speziell für den Eisenbahnverkehr entwickelten Konstruktion der Trogbrücken mit dicken Fahrbahnblechen, auch bekannt als Dickblech‐Trogbrücken. Im Fokus stehen Fragen der Ermüdungsbemessung dieses Brückentyps, die anhand von Bauteilversuchen verifiziert und in Form von Konstruktionsempfehlungen beantwortet werden.

Authors: Patil Yuvraj , Misra Rajneesh 
Published: June 2018

AbstractOrganic solar cells (OSCs) have gained attention of the scientific community from the last decade and are now considered as one of the most important source for low‐cost power production. The recent rapid progress in non‐fullerene acceptors in BHJ indicates that they have potential to compete with fullerene‐based BHJ OSCs. The present review addressed the systematic comparison among various acceptors (diketopyrrolopyrrole (DPP), benzothiadiazole (BTD) and perylenediimide (PDI) based acceptors) in order to design and improve the performance of small molecules based non‐fullerene acceptors. This review focuses on the performance of small molecule non‐fullerene acceptors based on DPP, BTD and PDI for OSCs with respect to the change in molecular structures, energy levels, and PCE. A systematic comparison on the effect of molecular architecture, side chains on their performance is provided with the intention of evaluating the challenge to make highly efficient acceptors for the next generation organic photovoltaics.
A review of textile industry: Wet processing, environmental impacts, and effluent treatment methods

Published: June 2018

AbstractThe word “textile” means to weave and was taken from the Latin word “texere.” Nowadays, textiles not only fulfill humankind's basic necessity for clothing, they also allow individuals to make fashion statements. As one of the oldest industries, the textile industry occupies a unique place in India. It is responsible for 14% of the total industrial manufacture in India. However, the textile industry is also considered to be one of the biggest threats to the environment. Pretreatment, dyeing, printing, and finishing operations are among the various stages of the industrial textile manufacturing process. These fabrication operations not only utilize huge quantities of power and water, they also generate considerable amounts of waste. The textile industry utilizes a number of dyes, chemicals, and other materials to impart the required qualities to the fabrics. These operations produce a significant amount of effluents. The quality of effluents is such that they cannot be put to other uses, and they can create environmental problems if they are disposed of without appropriate treatment. This review discusses different textile processing stages, pollution problems associated with these stages, and their eco‐friendly alternatives. Textile wet processing is described in detail, as it is the key process in the industry and it also generates the greatest amount of pollutants in textile processing. The environmental impact of textile effluents is discussed, as textile effluents not only impose negative effects on the quality of water and soil, they also imperil plant and animal health. In this paper, various methods for treating textile effluents are described. Discussion of physical, chemical, biological, and advanced treatment technologies of effluent treatment are included in this paper.

AbstractThis paper aims to identify the positive and negative aspects in the sustainability reporting framework proposed by the Global Reporting Initiative (GRI). The research was conducted through content analysis of 27 companies’ responses to three questions: “Why does the company where you work prepare a sustainability report?” “What are the positive aspects you identify in the framework for GRI reporting?” and “What are the negative aspects you identify in the framework for GRI reporting?” The questionnaire was sent to all Brazilian companies that published sustainability reports using the GRI guidelines between 2011 and 2013 related to the base year 2010. We found that respondents viewed the GRI guidelines and the reports they created as management tools for sustainability and that they assist in benchmarking sustainability performance and legitimizing the sustainability actions of the organization. Furthermore, some respondents indicated that the reports themselves are marketing tools. On the other hand, the respondents reported difficulties in understanding the proposed GRI guidelines. They considered the guidelines complex, ambiguous, and too flexible, which undermined both the standardization of the reports and the ability to compare reports. Based on these comments, it is recommended that the GRI develop a simpler and less flexible reporting methodology.
