Published: August 2021

Non healthy oils & fats consumption in foods is the major reason of obesity in human beings.
Common cooking oils & fats are composed of medium and long chain triglycerides. Each triglyceride consist of fatty acids called medium and long chain fatty acids abbreviated as (MCFAs & LCFAs). The ratio of LCFAs is mostly higher than the MCFAs in common cooking oils to be to be suitable for heat stress applications like cooking and frying. On the other side there is natural dietary fats are rich in Medium-chain fatty acids (MCFAs) like coconut oil and dairy fats. Also there are synthetic medium-chain triglyceride (MCT) oils which are synthetized by a processes called fractionation that extracts the MCFAs as caprylic and capric acid from the other fatty acids in the coconut or palm kernel oil.
The MCFAs, shows substantial metabolic advantage compared to LCFAs. MCFAs are a preferred source of energy (b-oxidation). The last 20 years studies conﬁrmed the potential of MCFAs to reduce body weight and may reduce fasting lipid levels more than oils rich in LCFAs. The same is true for glucose levels.
In this study, the authors did chemical and instrumental studies on dietary structured MLCT and non-structured MCT/LCT cooking oils which were used for producing for weight reduction and obesity control purpose Capric /caprylic MCT oil was used as a source of MCFAs for producing of novel. Different sources of long-chain triglycerides (LCFAs) have been used including sunflower oil (SFO), Canola oil(CNO), high oleic sunflower oil (HOSFO), palm oil (PO) and double fractionated palm olein (DFOlein).
The following techniques have been used for preparation of structured and non structured cooking oils in this study :
1-Physical blending.
2 - Chemical interesteriﬁcation in a multipurpose batch reactor.
2- Enzymatic interesterification using immobilized Lipase enzyme in pilot scale packed bed reactor (PBR).
Different analytical and instrumental techniques were used in this study including Gas chromatography (GC), high-performance liquid chromatography (HPLC), Differential scanning calorimeter (DSC), Rancimate, and smoke point tester.
The study shown that the non-structured MCT/LCT oils gave reasonable heat stability, higher smoke points compared the structured MLCT oil which make it more suitable for cooking and frying applications.
The chemical and enzymatic interesterification (CIE & EIE) technique yield a real structured MLCT oil which is more effective in caloric reduction and obesity control purpose during long term consumption in dietary foods, however, due to its much lower smoke point compared to its relative LCFAs oil so it will be suitable only for cold applications like salad dressing and other culinary applications. But not suitable for heat stress applications like deep or shallow frying.

New Criterion of Robust Hܣ Stabilization for Uncertain Neutral Systems
Authors: Lu Jiyong 
Published: August 2021

The problems of delay-dependent robust stability and stabilization for a class of uncertain neutral systems are investigated in this paper. At first, by constructing a new Lyapunov functional and using the Lyapunov stability theory, a new delay-dependent condition which renders the system with no external disturbance and input to be asymptotically stable is obtained and given by a linear matrix inequality. Then, based on the obtained condition, a state feedback stabilize law is designed, which guarantees closed-loop neutral systems are asymptotically stable for all the permitted uncertainties when the external disturbance is naught, and it can also guarantee the closed-loop systems have performance under the external disturbance. The model of neutral systems with both the uncertainty and the disturbance discussed in this paper has rarely been considered before.

Published: August 2021

As indispensable as communication has been to human endeavors, geographical and physical distance would have been a barrier to its effective deployment if not for the advent of wireless mobile communication. In the world today, most of the developments we see in all spheres of our modern life are influenced by communication technologies. However, the performance of each modulation scheme deployed in the communication system dictates the Quality of Service (QoS), effective cost management, efficient power, available bandwidth, Bit Error Rate (BER), and Signal to Noise Ratio (SNR). Extensive research has been done with different authors proffering wide ranging solutions for generalized selection combining (GSC) algorithms in the presence of noise and interfering signals. Some of the reported approaches include varying modulation schemes, changing the channel, and using different equalizing techniques. Many of these proposed solutions worked effectively in some areas while they understandably left other areas untouched, others show better performance by analyzing the channel using; Log-likelihood Ratio (LLR), integral expression, and multiple-mode transmission scheme which in turns proof to be of better performance with a good result. Despite all the efforts, overcoming the issue of noise interference in the communication channel has still been somewhat elusive. Conclusively, to reduce noise to the barest minimum in mobile/cellular communication, this review proposes modulation scheme synchronization with combined diversity technique over an improved channel that is less prone to noise.

ObjectiveAlthough most total knee replacement (TKR) recipients report less pain and improved function after TKR, many remain sedentary. We aimed to understand TKR recipients’ motivations for undergoing TKR, perceptions of and goals related to physical activity, and the role, if any, that activity monitors might play in their recovery.MethodsWe conducted a qualitative study, individually interviewing 27 participants who had recently undergone or were about to undergo TKR. We conducted a thematic analysis to better understand participants’ views of the benefits and barriers to physical activity after TKR.ResultsWe identified nine themes and one subtheme that identify patients’ initial motivations for undergoing TKR and may help TKR recipients achieve increased activity levels and a perceived successful recovery. Some key messages that emerged from our work include the following: exercise is necessary for physical and mental health, pain and functional limitation interfere with daily life, tracking steps motivates individuals to increase activity levels, and different incentives (for engaging in physical exercise and using an activity monitor) are effective for different individuals.ConclusionParticipants recognized the health benefits of physical activity, and many believed activity monitor use would help them become more active after surgery. Both external and internal factors played a role in motivating individuals to become more active and wear activity monitors.

Published: August 2021

AbstractAntibacterial materials are highly demanded in treatment of bacterial infection, especially severe ones with multidrug‐resistance. Herein, pH‐responsive polypeptide, i.e., poly‐L‐lysine modified by 1‐(propylthio)acetic acid‐3‐octylimidazolium and citraconic anhydride (PLL‐POIM‐CA), is synthesized by post‐polymerization modification of poly‐L‐lysine (PLL) with 1‐(propylthio)acetic acid‐3‐octylimidazolium (POIM) and citraconic anhydride (CA). It is observed that PLL‐POIM‐CA is stable under normal physiological condition, while CA cleaves rapidly at weakly acidic environment like bacterial infectious sites. The hydrolyzed PLL‐POIM‐CA exhibits excellent broad‐spectrum antibacterial activities against Gram‐negative bacteria of Escherichia coli and Gram‐positive bacteria of Staphylococcus aureus and methicillin‐resistant Staphylococcus aureus (MRSA). In particular, the minimum inhibitory concentration (MIC) against multidrug‐resistant bacteria like MRSA is as low as 7.8 µg mL−1. Moreover, PLL‐POIM‐CA exhibits good biocompatibility with mouse fibroblast cells (L929) in vitro and improved hemocompatibility with an HC50 exceeding 5000 µg mL−1. Therefore, PLL‐POIM‐CA displays an excellent bacteria versus cells selectivity (HC50/MIC) over 534, which is 53 times higher than natural antimicrobial peptide of indolicidin. It is further demonstrated in vivo that the antimicrobial polypeptide effectively accelerates MRSA‐infected wound healing by relieving local inflammatory response. Therefore, this targeted antimicrobial polypeptide has broad application prospects for the treatment of multidrug‐resistant bacterial infection.

AbstractMulti‐resonance thermally activated delayed fluorescence (MR‐TADF) offers an exceptional solution for narrowband organic light‐emitting diode devices in terms of color purity and luminescence efficiency, while the development of new MR skeleton remains an exigent task. It is hereby demonstrated that a simple modification of the B (boron)−N (nitrogen) framework by sp3‐carbon insertion will significantly bathochromic shift the short‐range charge‐transfer emission, boost the reverse intersystem crossing process, and improve the device performances. The bis(acridan)phenylene‐based skeleton developed in this contribution presents a non‐planar conformation with functional sites to facilely introduce isolating units, deriving two luminophores with quantum yields approaching 90% in film state and narrowband emission. Corresponding green‐emissive devices realize superior performances compared to the planar carbazolyl‐based MR‐TADF analogs, featuring a maximum external quantum efficiency (EQEmax) up to 28.2% and small efficiency roll‐off without the involvement of any sensitizing host.

Published: August 2021

AbstractMetal–insulator–metal (MIM) nanocavity, as a lossy Fabry–Pérot (FP) scheme, has been widely studied for color filter and perfect absorber functionality, which can be integrated into functional photonic devices. However, such triple‐layered MIM still lacks the ability to induce multiple intensity levels for meticulous grayscale imaging because of strong spectral sensitivity to cavity thickness variation. Moreover, the MIM stack remains unexplored to multiplex a near‐field nanoprinting and holographic imaging because it is challenging to break the mutual dependence relation between the intensity and phase shift. Herein, a new film stack of dual‐Fabry–Pérot (DFP) nanocavity is proposed to create triple‐fold freedom in light modulations: intensity, phase shift and operation wavelength, which can be respectively modulated by the top/bottom/total cavity length. By spatially arranging the stepwise nanocavities, the designed DFP pattern can show multiplexing dual‐channel imaging, which encrypts/conceals a grayscale nanoprinting image and simultaneously projects a far‐field holographic image. Such DFP strategy allows for new possibility of independent light modulation and creates new dimensional degree of freedom for thin‐film nanocavity. The proposed functional DFP strategy enriches the subwavelength building block design for metasurfaces and thin‐film stacks, which would promisingly empower advanced applications in information multiplexing, imaging encryption/concealing, and many other related fields.

AbstractHigh efficiency deep‐blue emitters are one of the basic requests for an outstanding full‐color organic light emitting diode (OLED) display. Herein, a linear D‐A‐D diphenylpyrazine structure is designed for maximizing the π‐conjugation effect, whilst two deep‐blue (DPP‐DPhC and DPP‐D3C) and one blue (DPP‐DTPA) fluorophores are synthesized by incorporating the N‐phenylcarbazole and triphenylamine donor units, respectively. As a result, they emit bright deep‐blue to blue fluorescence with the luminescence quantum yields of 0.312–0.888 in solid state. Fortunately, all the non‐doped and doped OLED devices show deep‐blue (N‐phenylcarbazole disubstituted compounds, DPP‐DPhC and DPP‐D3C) and blue (triphenylamine derivative, DPP‐DTPA) electroluminescence (EL) performance with the maximum external quantum efficiencies (EQEs) of >4%. Comprehensively considering other parameters, the deep‐blue non‐doped OLED device based on DPP‐DPhC exhibits the best EL performance with the maximum EQE of 5.73% with the Commission International de L'Eclairage (CIEx,y) coordinate of (0.151, 0.078) among them. These results demonstrate the feasibility of this strategy and provide a simple method to achieve high efficiency deep‐blue emitters.

Published: August 2021

Abstract“Transient” resistive random access memory (RRAM) has attracted tremendous research interests in recent years, due to its biodegradable characteristics and data storage capability. Zinc oxide (ZnO) has been widely used as the biodegradable and biocompatible material. However, research on ZnO based‐RRAM shows undesired performance due to masses of intrinsic defects and low crystallinity in ZnO films when deposited using sputtering and so on. In this work, excellent crystallinity and oxygen vacancy‐poor electrochemically‐deposited zinc oxide (ED‐ZnO) films are utilized as the active layer for fabricating transient resistive memory device with a structure of Ag/ED‐ZnO/W. This ED‐ZnO RRAM device exhibits uniform switching voltage, stable retention time (over 104 s) at 37 °C, and outstanding endurance up to 2500 cycles without obvious degradation. Additionally, a fully degradable RRAM device is fabricated by water‐assisted transfer printing method and it can be dissolved completely after immersed in phosphate buffered saline solution without encapsulation layer after 60 min. The cell toxicity test demonstrates the biocompatibility of the dissolved memory device. These results suggest that the ED‐ZnO based transient RRAM has a significant potential for data storage applications in transient electric system and implantable biomedical device.

Published: August 2021

AbstractImpellers in stirred vessels are often characterized by dimensionless numbers such as the power and flow numbers. These are often crucial in determining mixing performance. Previous studies for high‐shear mixers have yielded correlations between the power, flow, and mixer geometries, since in these mixers the flow can be independently varied. For stirred vessels, dimensional analysis is typically used to develop such correlations, leading to less accurate predictive models. Here, we combine an analysis based on a balance of angular momentum balance with computational fluid dynamics simulations to comprehensively study the effect of impeller geometry on the relationship between power and flow. The results allow for the prediction of the flow generated by the impeller based on the easily measurable impeller power consumption and the geometrical dimensions of the impeller. The models are accurate over a wide range of geometries. Furthermore, we are able to predict both the primary and total flows.
