Authors: Katili Jenet
Published: October 2021

PT. Garuda Top Plasindo is a family business that was established in 2001. It is located at Rungkut Industri III/17, Surabaya. Its main product is SUAPI. SUAPI is a brand of its disposable cutleries such as spoons, forks, knives, drinking cups, chopsticks, and many more. As a big company, PT. Garuda Top Plasindo also has some competitors, two of which are Cicipi and Victory. Those two brands also sell disposable cutleries but with a lower price. Because of that, the company has a problem related to the price. The company has lost some of its distributors because they prefer to buy cheap products from those two other brands. However, SUAPI has some uniqueness that the others do not have. The first is safe. The company uses food-grade material to produce the cutleries. Using safety cutleries is important that we can be spared from chemical material that can cause illness. The second is variety. SUAPI has various designs and colors that will make your party more colorful. Therefore, the solution of the problem is emphasizing the two selling points in a promotional video to increase the brand awareness. It is a good solution for the company because they will have a new tool that can help them in explaining the USP of SUAPI to the customers. This tool will show the uniqueness of SUAPI that the other brands do not have. There are several benefits that the company will get from this project. First, many customers and prospects will know about the uniqueness of SUAPI. Second, the company will find it easier to promote the products to the target markets. Keywords: brand awareness, unique selling points, promotional video.

Deconstruction of Male and Female Characters’ Qualities in Zootopia
Authors: Teddy William
Published: October 2021

This research aims to analyze the representation of male and female characters’ qualities that are portrayed in  Zootopia. The research also aims to show how the qualities are deconstructed as well as how to deconstruct the deconstruction in the movie as a method of analysis. Through the analysis the writer finds that the representation of qualities in Zootopia follows the traditional gender stereotypes, where men are considered superior than women. However, as the story progresses, the writer finds that the qualities in the movie are gradually deconstructed, showing that women are superior than men. After deconstructing the deconstruction in the movie, the writer finds that meaning can “disseminate” or can be perceived in different ways. Furthermore, from the analysis, the writer finds that both oppositions are actually interdependent to each other and complement as a whole. This means neither of the oppositions is stronger or weaker than the other. Keywords: Gender roles, Masculine and Feminine Gender Stereotypes, Deconstruction, Binary Opposition, Violent Hierarchy
Oral Corrective Feedback and Learners’ Uptake in Teenage EFL Class
Authors: Ovilia Ivana
Published: October 2021

This study was done to find out: (1) the types of oral corrective feedback (CF) strategies, (2) the types of learners’ uptake, and (3) the types of learners’ uptake elicited in relation to the teacher’s types of oral CF. In order to answer the research questions, the writer applied two theories, Sheen and Ellis (2011) for oral CF strategies and Panova and Lyster (2002) for the types of learners’ uptake, as the guideline. This study used qualitative approach, using audio recording. The findings showed that there were forty three (43) oral CF occuring in the class, and forty one (41) uptakes elicited in relation to teacher’s oral CF. There were 2 (two) oral CF which did not result in uptake. Six (6) out of nine (9) oral CF strategies and seven (7) out of ten (10) types of learners’ uptake occurred in the class.  Didactic Recast was the most frequently applied oral CF strategies, whereas Repetition was the most frequently applied learners’ uptake type. There were 18 types of oral CF strategies and learners’ uptake sequences occurring in the class, and the most occurring sequence was Didactic Recasts – Repetition, with total 11 times. There were some possible reasons why uptakes did not occur:   learners were taking too long to answer or the teacher did not want to wait longer expecting that learner had already known the correct form through prior explanation. In order to maintain the class running smoothly, the teacher sometimes was faced to a situation when none uptakes were elicited from the learners. Keywords: corrective feedback, oral corrective feedback, uptake

The Paradoxical World of Psycho-Pass Anime Series
Authors: Harly Natasha , Limanta Liem Satya
Published: October 2021

Psycho-Pass is one of the most well-known examples of dystopian anime. The story is set in 22nd century Japan, where the country is ruled by the Sibyl System. The world is portrayed to be an ideal world that is seemingly crime-free, yet the world also contained many problems that offset how ideal it seemed. In this paper, we are concerned about how Psycho-Pass can be categorized as a paradoxical world. Therefore, we aim to show the ways that the world of Psycho-Pass is indeed paradoxical by using utopia and dystopia theories. Through our analysis, we found that elements of both utopia and dystopia are present in Psycho-Pass. The world of Psycho-Pass is paradoxical in that it is ideal and faulty at the same time. Keywords: anime, paradoxical, utopia, dystopia.

Bledug Kuwu is one of the geological phenomena as a mud volcano that occurs in Kuwu, Purwodadi, Grobogan, Central Java, Indonesia. The evaluation of Bledug Kuwu’s clay as one of the adsorbents for synthetic dyes has been carried out. The preparation of the adsorbent started with washing the clay with distilled water, followed by activation with a solution of hydrochloric acid (1 M) under mechanistic stirring for overnight. The C−H and O−H groups found on the clay adsorbent could attract methylene blue by dispersion forces and hydrogen bonding. Hydrocloric acid activation process for clay can increase surface area from 49 to 70 m2.g−1, meanwhile, reducing the average crystal size from 48.3 to 43.4 nm. The dye removal capacity increased from 34 to 40 mg.g−1 in corresponding to the increase of the temperature from 30 to 50 °C. The results showed that the equilibrium adsorption capacity of activated Bledug Kuwu’s clay reached 99% in an adsorption time of 20 min. The kinetic models of methylene blue adsorption onto BKC and ABKC adsorbents follow the pseudo-second order and the adsorption process is spontaneous with free energy (ΔG) as −23.519 kJ.mol−1.

SAMHSA says block grants can be used for for‐profits
Authors: Knopf Alison
Published: October 2021

Our article on for‐profit opioid treatment programs (OTPs) being able to use the Substance Abuse Prevention and Treatment block grant (see “SAMHSA moves toward allowing funds to go to for‐profit OTPs,” ADAW Oct. 11; https://onlinelibrary.wiley.com/doi/10.1002/adaw.33217) elicited a lot of attention. This is to be expected. It has always been assumed that the Substance Abuse and Mental Health Services Administration (SAMHSA) prohibits awards to for‐profit entities, as laid out by the Public Health Service Act. However, with 60% of OTPs now for‐profit, opening up this funding, which was spurred by the recent approval of methadone vans, has become a reality.

A T‐Junction Dual Nanopore for Single Nanoparticle Analysis
Authors: Liao Caizhi , Antaw Fiach , Wuethrich Alain , Trau Matt
Published: October 2021

Label‐free detection methods such as resistive pulse sensing (RPS) have become a pivotal platform for the characterizations of nanoscale objects, providing real‐time monitoring and single‐molecule resolution. Major challenges for RPS platforms include the short translocation time of nanoscale objects passing through the pore and limited dynamic range due to the need for particle sizes to be within 10−90% of the pore size. These issues severely limit the fidelity of the measured signals, particularly when measuring unknown samples. Herein, a T‐junction‐shaped dual pore system that slows down the motion of translocating nanoparticles is proposed, and that allows particle translocations to be unambiguously allocated to one of the two pore structures. Moreover, because the two pore structures are of different sizes, the size range of particles that may be measured without clogging is increased. The prepared dual pores afford to measure the size features and surface charge properties of nanoparticles with high accuracy. Importantly, the dual‐pore system enables the study of the dynamic motion behaviors of adjacent nanoparticles. The application of these dual pores for characterizing the protein corona of bioparticles is exemplified.

Published: October 2021

High‐rate electrochemical CO2‐to‐CO conversion provides a favorable strategy for carbon neutrality. Molecular catalysts, especially those with isolated metal active centers, are known to be the efficient CO2‐to‐CO electrocatalysts due to their high selectivity and outstanding instinct activity; however, the controllable scale‐up synthesis and durable utilization at industrial current densities still remain a challenge. Here, it is developed a molecularly dispersed cobalt phthalocyanine loaded on carbon nanotube for high‐current long‐term CO2‐to‐CO electrolysis. The resultant catalyst exhibits a high CO selectivity with a maximum Faradaic efficiency of 97% and performs a current density of −200 mA cm−2 in a flow cell with a TOF of 83.9 s−1, which is among the best of CO‐selective electrocatalysts. With a series of impregnation loading experiments, the process of molecular‐dispersion or aggregation is investigated. In addition, the application of selective and durable electrolysis at a current of 0.25 A is realized up to 38.5 h in a scale‐up MEA configuration. Subsequent characterization shows robust durability closely related to the dispersion of CoPc. This study provides a triumph to catalyze commercial‐scale CO production using molecularly dispersed phthalocyanine electrocatalysts.
Ultrahigh Throughput On‐Chip Synthesis of Microgels with Tunable Mechanical Properties
Authors: Wu Jingyu , Yadavali Sagar , Issadore David A. , Lee Daeyeon
Published: October 2021

Microgels, 1–100 µm sized hydrogel particles, have emerged as versatile materials for constructing injectable tissue scaffolds, with superb control over various properties. Microfluidic synthesis of microgels offers significant advantages over conventional batch synthesis such as high uniformity and precise control over emulsion size. Despite these positive attributes, the gelation of microfluidic droplets is typically performed off‐chip, compromising the particle homogeneity, and confounding the ability to control their mechanical properties. To address this, a multistep microgel synthesis line is developed, comprising of a flow focusing droplet generator followed by a UV‐curing stage that delivers a precise UV dosage to each droplet, allowing precise control of the mechanical properties of hydrogel microparticles. Furthermore, parallel operation of 4080 identical synthesis lines on a single chip is demonstrates, generating precisely defined microgels at a throughput appropriate for commercial and clinical translation. The system is validated by generating poly(ethylene glycol) diacrylate microgel particles with a diameter down to 40 µm at a throughput above 1 kg h−1 (106 particles s−1), with a coefficient of variation of 3%. It is demonstrated that the stiffness of the microgels can be precisely controlled from 103 to 104 Pa by varying the UV dosage.
Rotation and Revolution of Optically Trapped Gold Nanorods Induced by the Spin and Orbital Angular Momentum of a Laguerre–Gaussian Vortex Beam
Authors: Karpinski Pawel
Published: October 2021

Optical trapping, spinning, and orbiting of nanoparticles allow the study of nanoscale mechanical, thermal, and optical effects. A circularly polarized Laguerre–Gaussian beam can simultaneously rotate a gold nanorod about its symmetry axis while revolving it around the beam's symmetry axis. The first motion is rotational in character, whereas the second is translational. Effective temperatures of each motion are experimentally obtained and compared with predictions from the Hot Brownian Motion theory. The results also show the optical‐to‐mechanical torque‐transduction efficiency to be equal for the spin and orbital angular momentum.
Strong and Atmospherically Stable Dicationic Oxidative Dopant

Published: October 2021

Increasing the doping level of semiconducting polymer using strong dopants is essential for achieving good electrical conductivity. As for p‐dopant, raising the electron affinity of a neutral compound through the dense introduction of electron‐withdrawing group has always been the predominant strategy to achieve strong dopant. However, this simple and intuitive strategy faces extendibility, accessibility, and stability issues for further development. Herein, the use of dicationic state of tetraaryl benzidine (TAB2+) in conjunction with bis(trifluoromethylsulfonyl)imide anion (TFSI−) as a strong and atmospherically stable p‐dopant (TAB–2TFSI), for which the concept is hinted from a rapid and spontaneous dimerization of radical cation dopant, is demonstrated. TAB–2TFSI possesses a large redox potential such that it would have deteriorated when in contact with H2O. However, no trace of degradation after 1 year of storage under atmospheric conditions is observed. When doping the state‐of‐the‐art semiconducting polymer with TAB–2TFSI, a high doping level together with significantly enhanced crystallinity is achieved which led to an electrical conductivity as high as 656 S cm−1. The concept of utilizing charged molecule as a dopant is highly versatile and will potentially accelerate the development of a strong yet stable dopant.

Published: October 2021

Carbon dots (CDs) with long‐wavelength absorptions and emissions are highly desired for biological applications. Herein, we report a new supra‐CDs strategy to construct long‐wavelength absorption bands based on fused CDs aggregates (f‐CDAs) through a concentration‐induced interparticle dehydration process among green emissive CDs (r‐CDs) under solvothermal treatment. The obtained fused f‐CDAs exhibit an obvious absorption band in 550–700 nm and significantly enhanced deep red fluorescence in N,N‐dimethylformamide with photoluminescence quantum yields of 15.6% and high photothermal conversion efficiency up to 26.1% in water. Benefiting from the high photothermal performance, in vivo tumor photothermal therapy has been realized via intratumoral injection of f‐CDAs under 655 nm laser irradiated at 0.5 W/cm2.

The effect of GNP loadings on the mechanical (tensile and impact properties) and thermal properties of the rubber toughened epoxy/GNP nanocomposites were evaluated. The results showed that the incorporation of GNP had optimally improved the tensile strength and tensile modulus by 70% and 74%, respectively, at 0.6 wt% filler loading. Thermogravimetric analysis (TGA) andTgincrement result proved the barrier effect via delaying decomposition process which induced by the layered structure of GNP and thus significantly enhanced the thermal stability of epoxy‐based resin, irrespective of GNP loadings (insignificant difference in the decomposition temperature). The fractured surfaces of these nanocomposites showed the good interfacial interaction between the matrix and the GNP nanofiller. X‐ray diffraction (XRD) analysis demonstrated the exfoliation and intercalation states of GNP dispersion in epoxy/LENR.

Znic‐air (Zn‐air) cell has gained lots of attention due to its high specific energy. High activity and good stability of bifunctional electrocatalysts are very critical for Zn‐air cell. Herein, Co particles embedded in highly porous N‐doping carbon nanocube (Co/HP‐NC) has been successfully fabricated by pyrolyzing bimetallic Co/Zn‐zeolitic‐imidazolate framework (ZIF) and further evenly loaded with metallic Ru nanoparticles to obtain Ru‐coated Co/HP‐NC (Ru@Co/HP‐NC). Benefiting from introduction of Zn, Ru@Co/HP‐NC shows the large pore volume, small Co particles, high surface contents of Co4N and pyridinic/graphitic N. Furthermore, theoretical and experimental results further demonstrate that synergy of Ru coating with Co/HP‐NC can greatly improve the oxygen reduction/evolution reaction (ORR/OER) property of Ru@Co/HP‐NC. Furthermore, Ru@Co/HP‐NC based Zn‐air batteries present the high open circuit potential of 1.4 V, large power density of ∼210 mW cm−2, high discharge capacity (791 mAh g−1) and super‐long cycling life (∼475 cycles) with small overpotantials (∼0.89 V). Notably, flexible Zn‐air cell with Ru@Co/HP‐NC cathode also displays excellent flexibility and superior cycling stability under different bending conditions. The work provides the simple and reliable way to prepare high‐efficient electrocatalysts for high‐performance metal‐air systems.

Based on the analysis of two sets of data (a cross‐sectional online survey of five product categories with an average sample size of 525 and a longitudinal telecommunications panel of more than two million respondents), this study detects a positive relationship between the market size (purchase penetration) of Iranian e‐brands (or websites) and the percentage of customers shared with other e‐brands. This finding is consistent with the well‐established Duplication of Purchase Law; it also holds over time and across different markets (e.g., repertoire vs. subscription). Hence, this study makes a twofold contribution to marketing knowledge. First, it expands the collection of empirical evidence concerning the Duplication of Purchase, which thus far is primarily within offline contexts and Western countries. Second, it addresses issues inherent to research on e‐loyalty, such as the over emphasis on evaluating loyalty for one e‐brand at a time via complex attitudinal measures. Accordingly, this study advances consumer buying behaviour research by clarifying that, similar to offline domains and other geographical areas, e‐loyalty in this buoyant Middle Eastern market divides across a small number of e‐brands. It is also best appraised through behavioural loyalty and by comparing multiple e‐brands competing within the same market. These outcomes translate into a series of practical guidelines for the strategic management of e‐brands, improving the practical understanding how e‐brands compete and grow.

The bioactivity‐guided isolation on the Scutellaria barbata extract resulted in the purification of four undescribed neo‐clerodane diterpenoids, scuttenlines A–D (1–4), alone with 20 known diterpenoids (5–24). The chemical structures of them were elaborated by extensive spectroscopic means, including 1D, 2D‐NMR and HR‐MS. The anti‐inflammatory potential ability of 1–24 was screened in lipopolysaccharide‐stimulated mouse RAW 264.7 cells. Scuttenline C (IC50=1.9 μM) and 18 (IC50=3.7 μM) exhibited potent activity to inhibit NO production.

The global spread of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) has called for an urgent need for dedicated antiviral therapeutics. Metal complexes are commonly underrepresented in compound libraries that are used for screening in drug discovery campaigns, however, there is growing evidence for their role in medicinal chemistry. Based on previous results, we have selected more than 100 structurally diverse metal complexes for profiling as inhibitors of two relevant SARS‐CoV‐2 replication mechanisms, namely the interaction of the spike (S) protein with the ACE2 receptor and the papain‐like protease PLpro. In addition to many well‐established types of mononuclear experimental metallodrugs, the pool of compounds tested was extended to approved metal‐based therapeutics such as silver sulfadiazine and thiomersal, as well as polyoxometalates (POMs). Among the mononuclear metal complexes, only a small number of active inhibitors of the S/ACE2 interaction was identified, with titanocene dichloride as the only strong inhibitor. However, among the gold and silver containing complexes many turned out to be very potent inhibitors of PLpro activity. Highly promising activity against both targets was noted for many POMs. Selected complexes were evaluated in antiviral SARS‐CoV‐2 assays confirming activity for gold complexes with N‐heterocyclic carbene (NHC) or dithiocarbamato ligands, a silver NHC complex, titanocene dichloride as well as a POM compound. These studies might provide starting points for the design of metal‐based SARS‐CoV‐2 antiviral agents.

The application of dinuclear zinc catalysts in a dearomatization reaction has been developed. Catalytic asymmetric dearomatization [3+2] annulations of 2‐nitrobenzofurans or 2‐nitrobenzothiophenes with CF3‐containing N‐unprotected isatin‐derived azomethine ylides catalyzed by dinuclear zinc catalysts are realized with excellent diastereomer ratios (dr) of >20 : 1 and enantiomeric excess (ee) of up to 99 %. This protocol provides a practical, straightforward access to structurally diverse pyrrolidinyl spirooxindoles containing a 2,3‐fused‐dihydrobenzofuran (or dihydrobenzothiphene) moiety, and four contiguous stereocenters. Reactions can be performed on a gram scale. The absolute configuration of products is confirmed by X‐ray single crystal structure analysis, and a possible mechanism is proposed.

Published: October 2021

Process simulation based on physical models often faces computational problems with respect to convergence, especially if the underlying flowsheets are complex. The use of data‐driven surrogate models connected to flowsheets promises to overcome these challenges. Using the steam methane reforming process, this paper presents the development of surrogate models – artificial neural networks – for the key units of the process that are subsequently connected to form the entire flowsheet. The accuracy of the individual surrogate models is analyzed based on the test error; the accuracy of the flowsheet is evaluated by a benchmark process simulation performed in Aspen Plus®. Therefore, the predicted key variables, here outlet temperatures and compositions, are compared to the benchmark. It is shown that their maximum error is below the typical measurement error. The comparison of the accuracy of the surrogate‐based flowsheet simulation with the Aspen Plus® simulation proves to match very well, as long as the training ranges of the underlying surrogate models are not violated. The promising results of this paper pave the way for future work, such as the optimization of process parameters or superstructure optimization.

Published: October 2021

Comprehensive Summary

Atropisomeric anilides are one of important C—N axially chiral compounds. Compared with the N‐terminal functionalization to prepare such compounds, C‐terminal functionalization strategies have been rarely reported. We describe herein an efficient synthesis of axially chiral anilides enabled by Pd‐catalyzed desymmetric Sonogashira cross‐coupling reactions with the use of a newly identified Ming‐Phos. Moderate to high yields with high enantioselectivities (up to 98% ee) were obtained.

Published: October 2021

Nitric oxide (NO) and hydrogen sulfide (H2S) have been recognized as important signalling molecules involved in multiple physiological functions, including wound healing. Their exogenous delivery has been established as a new route for therapies, being the topical application the nearest to commercialization. Nevertheless, the gaseous nature of these therapeutic agents and their toxicity at high levels imply additional challenges in the design of effective delivery systems, including the tailoring of their morphology and surface chemistry to get controllable release kinetics and suitable lifetimes. This review highlights the increasing interest in the use of these gases in wound healing applications by presenting the various potential strategies in which NO and/or H2S are the main therapeutic agents, with focus on their conceptual design, release behaviour and therapeutic performance. These strategies comprise the application of several types of nanoparticles, polymers, porous materials, and composites as new releasing carriers of NO and H2S, with characteristics that will facilitate the application of these molecules in the clinical practice.
