Erindring om Ucayali: De historieløses historier
Authors: Veber Hanne
Published: August 2021

Hanne Veber: Memories of Ucayali. Accounts by the “People Without History” Ucayali is a river and an Amazonian region in eastern central Peru. It is also the scene of killings and atrocities including traffic in women and children in the recent past as part of a strategy to secure indigenous labor for the rubber barons during the infamous rubber boom in the Upper Amazon in the late 19th and early 20th centuries. Based on autobiographical narratives recorded from contemporary Asháninka leaders the articlediscusses how this historical background is recalled differently in oral traditions handed down from within families from parents to their children. These narratives build exclusively on local and contextual references and appear to be functions of individual needs and interests. Hence, Asháninka memories of the Ucayali come out in the plural as discontinuous personalized accounts associated with a multitude of juxtaposed temporalities. The article considers the way these varied recollections take on meaning in the context of forging a consciousness of an indigenous collectivity based on shared experiences – real and reconstructed. Considering that the incorporation of past events into discourse is always a reformulation of the events, the author points to the ongoing efforts of the Asháninka to secure control of their own social reproduction in the face of continuing efforts by outsiders - multinational companies and national society - to appropriate Asháninka territory and socio-cultural space. As memory is forged in a dialectic between individual interests and collective strategies in response to certain needs, the constitution of shared identity and collective memory becomes both a means and a result of political activism. Taking account of the fact that the Asháninka memories refuse to homogenize into one singular “history of the oppressed”, the article points to the way Asháninka historical narratives take meaning from the structure of their telling and provide the members of the collectivity with a sense of agency. The textual structures of the narratives indeed constitute cultural encodings of the basic process of social reproduction. Through the record of things their ancestors did, the Asháninka may recognize their ability to make their own world through personal and collective action. Through remembering they take possession of their own history and through its telling they take charge of the present.

KULTUREL DIVERSITET OG PSYKOLOGISK ENHED: Eksemplet religiøse ontologier
Authors: Lisdorf Anders
Published: August 2021

How do we explain that people believe in apparently bizarre things as in Evans-Prichards’s

study of the Azande beliefs in witches? It is argued that radically nativist theories on the

one hand and radically culturalist explanations on the other are inadequate. Rather, a

more detailed account needs to be worked out. Taking the example of religious ontologies

to which Azandes witches belong, it is argued that religious ontologies consist of a

relatively limited catalogue of counter-intuitive concepts on a worldwide basis. The

problem is then how to explain why only some of these concepts are present in one

culture and others in another culture. Also it is a problem how to explain why these

religious ontologies are relatively stable within one culture over long durations, that is,

why a kind of cultural inertia exists. It is argued that the mechanism which stabilises

cultural knowledge is validation contexts of this knowledge. Validation contexts are

situations in which some knowledge is validated as true and other as false. Among the

Azande these are the different oracles. The oracles are anthropomorphised in the ritual

situation. But they are also sociomorphised, that is, considered a part of the wider

society of the Azande. As society has a hierarchy, so do oracles. This creates a knowledge

hierarchy among them. Some oracles give the ultimate truth while others are not credible.

When questions about witches as causes of misfortune are verified in the highest oracle

they remain a part of the religious ontology, which is why they are later again inferred as

causes of misfortune and again put as questions to the highest oracle. This looping

could explain the cultural inertia which is often testified in many cultures.

Indledning: DET LADER SIG HØRE – FORSKELLIGT
Authors: Christensen Merete Kjær , Kjærgaard Carsten
Published: August 2021

Dette nummer af Tidsskriftet Antropologi sætter fokus på variationen i lydperception

og i de forskningsmæssige tilgange til lyd. Vi har inviteret og modtaget artikler fra mange

faglige traditioner for netop at bidrage til så meget støj som muligt. Forfatterne

repræsenterer – ud over antropologien – arkitektur, performancedesign, semiotik samt

tekniske og naturvidenskabelige fag. Så godt som alle artikler er baseret på empiriske

studier, der i sagens natur også har forskellige udgangspunkter, genstandsfelter og

metode: fra tekniske målinger, der registrerer objektive værdier, til interviews, der beskriver

subjektive vurderinger af lydes karakter og betydning. Denne faglige bredde kommer

også til udtryk i en terminologi, der – for antropologer – måske er en smule eksotisk.

Septimakkorder, efterklangstid og det energiækvivalente lydtryksniveau er blot nogle af

de fremmede fagord, som tidsskriftets læsere vil støde på.
BLINDHEDENSAKUSTISKE HORISONTER: Om auditive kundskaber og en akustisk virkelighed
Authors: Lundberg Pia
Published: August 2021

With reference to the pioneering research of the few anthropologists, who have made

sound an object of analysis, the article presents the author’s research in a blind community,

thereby calling to attention sound, soundscape, sound-knowledge and sound-skills.

The author takes a point of departure in empirical data from her fieldwork among blind

children and youth in Denmark 2000-2005. An example of the research field is the virtual

world of a computer game for the blind, which shows the difficulty of grasping the reality

of the surrounding world, when this reality consists of sound and sound materiality. The

article proposes that the players of the computer game create soundscapes, for example,

how a pole by the road utters a kind of pole speech, or that a farmhouse in the Wild West

makes its presence through significant farm-acoustics. In addition to new insights on

blindness, the blind lifeworld and other perceptual horizons and skills, the study offers

a cultural, scientific opening into objectifying both sound and sound perception as

cultural phenomena, hence to expand an understanding of sound, acoustics and the

auditory.
AT HØRE, AT HØRE EFTER, AT HØRE TIL: Strategier i forbindelse med høretab og høreapparater
Authors: Bisgaard Susanne
Published: August 2021

As long as the sense of hearing remains intact, the individual can participate in the

negotiation and production of social and cultural values in the contexts to which she or

he ascribes a meaning. But what happens when the sounds are muffled? The handling of

hearing loss is subject to substantial individual differences – some wish to participate in

all social contexts, others wish only to uphold contact to specific segments of the lifeworld.

The hard of hearing may be excluded from a number of contexts, but the hearing aid may

be a help to retain a position. Some use them in all their waking hours, others only in

specific contexts. The difference is due to physiological and technological circumstances,

because no two hearing losses are perceived in the same way. Moreover, the technology

of the hearing aid may help the user to hear better, but it does not restore natural hearing.

Typically, the hard of hearing go through a process, in which the physical hearing loss

is related to the lifeworld. In this process the individual moves from being a normal

hearing person to being hard of hearing. Being hard of hearing differed for the informants

from a wish to participate in social life to an utter loss of one’s functioning and a concern

with bodily appearance.

DER ER TO I ET MØDE: Perspektiver på kulturmødet fra psykiatrien
Authors: Johansen Katrine Schepelern
Published: August 2021

The psychiatric treatment system in Denmark is one of the institutions where the

meeting with the ethnic Other has gained increased attention in the last couple of

years. Even though this is being spoken of as a meeting, focus is normally only

on the ethnic patients, their culture, and the problems staff experience when

working with this group of patients. Doing anthropological research in the Danish

psychiatric system, makes it obvious, however, that the psychiatric system itself

plays an important part in the meeting. Psychiatry has its own way of understanding

what culture is, and its own way of framing how culture can be talked about.

Using a modern, relational concept of culture I will show how the psychiatric

departments can be perceived as producing their own culture and that this culture

plays an important part in how patients with another ethnic background than

Danish are perceived. Patients who are perceived as ethnic are often patients

that psychiatry finds it difficult to treat, either because the technology of treatment

is not suited to this group of patients, or due to the way psychiatry perceives the

relation between psychiatric disorder and culture.
KULTURMØDER TIL FORHANDLING: Betydningen af ‘kultur’ i praktiksamtaler med voksne med dansk som andetsprog
Authors: Tranekjær Louise
Published: August 2021

The article demonstrates how the combination of discursive psychology and

conversation analysis enables an examination of culture as a product of discursive

processes which are influenced and permeated by a broader social, discursive

and cultural context. In this way an understanding is presented of cultural

encounters as something which is not only determined by the background of the

participants but is a product of interaction and the resources used in the negotiation

of meaning and identity. The article is based on research of internship interviews,

that is, interactions between Danish employers and adult second language speakers

seeking an internship placement. Through examples from these interviews, it is

argued that culture can be analyzed by combining a micro-perspective on the

negotiation and organization of meaning in interaction with a macro-perspective

on interactions as a manifestation of a broader social, discursive and cultural

practice and organization.
SPROGMØDET SET MED KULTURTEORETISKE BRILLER
Authors: Risager Karen
Published: August 2021

The aim of this article is to show how language studies and cultural studies can

develop the interface between the two fields of study through a focus on language

as culture. Here the emphasis is not on the form aspect of language – its grammar

and phonology – but on the content side, its meaning-carrying and meaningcreating

aspect. The article looks at language and language encounters through

culture – theoretical glasses. It analyses linguistic practice as socially structured

meaning at both micro and macro levels. The concept of languaculture is useful

for this purpose. The concept may be analysed in three dimensions: a semanticpragmatic,

a poetic, and an identity dimension. These dimensions are illustrated

in an analysis of the slogan Buy some petit souvenir aus Dänemark! seen as a

part of the multilingual space of tourism in Europe.

Vi argumenterer for, at det kollektive feltarbejde påvirker forståelsen og genereringen af data og herved den etnografiske analyse. Samarbejde medvirker til, at data får et eksplicit udtryk, og giver mulighed for at udarbejde analyser med forskellige perspektiver og en stor mængde data på kort tid. Vi fremhæver vigtigheden af kritisk stillingtagen til, hvordan samspillet mellem data, metode og analyse bliver påvirket af at være to i felten. Artiklen tager afsæt i vores erfaringer fra et fem måneders feltarbejde i slummen i Nairobi, Kenya.

DATABESKYTTELSE OG DEN ANTROPOLOGISKE EXCEPTIONALISME
Authors: Albris Kristoffer
Published: August 2021

For udenforstående må etiske diskussioner inden for antropologiens verden fremstå besynderlige. På den ene side har antropologer gennem tiden været ekstremt hårde i deres domme over fagets problematiske historie i forhold til racespørgsmål, kolonialisme og repræsentationen af ikke-vestlige lande som tilbagestående (Asad 1973). Ligeså har der til tider været rødglødende debatter om de etiske implikationer af antropologens positionering (Agar 1996) for ikke at tale om spørgsmål vedrørende repræsentationen af andre kulturers forståelser af tid, kosmologi og virkelighed (Clifford & Marcus 1986; Fabian 1983; West 2007) samt løbende diskussioner om antropologers etiske pligt til at tale „sandhed til magt“ (Scheper-Hughes 1995).

Authors: Al-deen Fatama Sharf , Ba-Alwi Fadl Mutaher
Published: August 2021

Due to the rapid development in information technology, Big Data has become one of its prominent feature that had a great impact on other technologies dealing with data such as machine learning technologies. K-mean is one of the most important machine learning algorithms. The algorithm was first developed as a clustering technology dealing with relational databases. However, the advent of Big Data has highly effected its performance. Therefore, many researchers have proposed several approaches to improve K-mean accuracy in Big Data environment. In this paper, we introduce a literature review about different technologies proposed for k-mean algorithm development in Big Data. We demonstrate a comparison between them according to several criteria, including the proposed algorithm, the database used, Big Data tools, and k-mean applications. This paper helps researchers to see the most important challenges and trends of the k-mean algorithm in the Big Data environment.

Authors: Mukherjee Upasana , Thakkar Vandana , Dutta Shawni , Mukherjee Utsab , Bandyopadhyay Samir Kumar
Published: August 2021

The growth of regularly generated data from many financial activities has significant implications for every corner of financial modelling. This study has investigated the utilization of these continuous growing data by a means of an automated process. The automated process can be developed by using Machine learning based techniques that analyze the data and gain experience from the underlying data. Different important domains of financial fields such as Credit card fraud detection, bankruptcy detection, loan default prediction, investment prediction, marketing and many more can be modelled by implementing machine learning methods. Among several machine learning based techniques, the use of parametric and non-parametric based methods are approached by this research. Two parametric models namely Logistic Regression, Gaussian Naive Bayes models and two non-parametric methods such as Random Forest, Decision Tree are implemented in this paper. All the mentioned models are developed and implemented in the field of Credit card fraud detection, bankruptcy detection, loan default prediction. In each of the aforementioned cases, the comparative study among the classification techniques is drawn and the best model is identified. The performance of each classifier on each considered domain is evaluated by various performance metrics such as accuracy, F1-score and mean squared error. In the credit card fraud detection model the decision tree classifier performs the best with an accuracy of 99.1% and, in the loan default prediction and bankruptcy detection model, the random forest classifier gives the best accuracy of  97% and 96.84% respectively.

Published: August 2021

Background: The outbreak of the COVID-19 epidemic left no nation indifferent in adopting measures to fight against the spread of the disease. This survey aimed at assessing the knowledge, attitude, and practice of Cameroonians towards preventive measures against the spread of COVID-19 in Cameroon.

Methodology: It was a cross-sectional online survey conducted nationwide via self-administration of a google form questionnaire in March 2020. Questionnaires were shared via Facebook and WhatsApp. Being a Cameroonian based in Cameroon was the main inclusion criteria. Data were analyzed using SPSS software.

Results: Amongst the 444 respondents who completed the survey, 232(52.3%) were males and females 212 (47.7%) with the majority, 221 (49.8%) between the ages of 26 to 35. Most, (99.6%) respondents had heard of COVID-19 mainly via social media 244 (55.0%) and TV/Radio, 139(31.3%). Difficulty in breathing was the most known symptom 402(90.54%). Cameroonians are quite knowledgeable about COVID-19 (444/446 i.e. 99.6% of respondents). Less than a half, 174 (39.19%) were aware of; 13 preventive measures and over 384 (86.49%) of 7 additional measures. More than half of the participants 261(58.8%) were optimistic that the pandemic will stop if people respect the hygienic and governmental preventive measures. A majority, 91% affirmed practicing handwashingbut only 76(19.3%) did it properly. Participants demonstrated less compliance to social distancing, 230(51.8%). A significant relationship was noted between knowledge on COVID-19 and handwashing with soap (p=0.005; r=0.320) as well as the use of face masks (r=0.701, p=0.001).

Conclusion: The governmental measures and hygienic preventive measures are known to Cameroonians but the compliance to these measures is moderate.
Crop Rotation: A Sustainable Practice for the Management of Diseases
Authors: Shimada Belmiro Saburo , Simon Marcos Vinícius , Souza Inglid Laís Batista Cunha de , Tonin Fabiana
Published: August 2021

The management and environmental impacts influence agricultural production, diseases, in turn, can interfere and cause damage to the crop at different times and parts of the plant, due to economic loss, it is necessary to use disease control methods. To maintain sustainable agricultural production, disease management is necessary. Many methods are adopted in agriculture during its development, and led to the implementation of various production systems, including the no-till system, which helped boost production. However, no-tillage was found to have several soil conservation problems, making it necessary to adopt another practice in this system, which is crop rotation, which emerged as a sustainable means of soil conservation, bringing several benefits. Crop rotation is the planned and orderly alternation of different crops in a given period of time and in the same area, making the development and survival of pests and pathogens that affect crops difficult. Along with sustainable disease management using biological control and methods plant-based, allowed for better disease management in agriculture and provided a more sustainable production environment. Crop rotation is important in disease control because it can be a preventive practice to provide diversity to the system through breakage cycles. The control of these diseases can be done through the biological control of pests and plant extracts.

OPTIMALISASI KEARIFAN LOKAL PADA PENGAJARAN INTEGRATED LANGUAGE SKILL MENGGUNAKAN METODE BLENDED LEARNING
Authors: Hartati Elysa
Published: August 2021

Culture is an ancestral heritage that contains many moral values to learn. However, the current young generation seems reluctant to learn about the culture in their environment or from the teaching point of view in schools it does not provide a platform to introduce culture to their students. Even though by integrating cultural values in learning, especially language learning, it can add to students' repertoire of loving their own culture because there are many values of local wisdom contained in it. By inserting examples of cultural heritage such as wayang orang, traditional houses, traditional events can be used as interesting learning materials for students because they remind them of the rich ancestral heritage in the texts they are studying. The use of the blended learning method is also a good alternative in optimizing local wisdom in teaching integrated language skills. By utilizing their own devices, they can have access to search for information from various sources such as YouTube, podcasts, and several websites to enrich their understanding of the culture in their environment. From these devices they can also help promote local culture in their environment. And on the other hand, teachers also have a role as cultural promoters through learning materials in the form of texts that they teach.
 
Abstrak: Masuknya budaya asing yang masif diduga akan membawa penurunan pengakuan budaya lokal oleh generasi muda khususnya anak-anak sekolah. Padahal, budaya lokal tersebut tetap dapat diajarkan secara terpadu dengan menyisipkan kearifan lokal melalui teks yang digunakan sebagai bahan dan media belajar mengajar khususnya pada mata pelajaran bahasa. Artikel ini bertujuan untuk memaparkan bagaimana mengoptimalkan kearifan lokal dalam pengajaran keterampilan berbahasa terpadu melalui metode blended learning. Dengan meman­faat­­kan pendekatan POACE (Planning, Organizing, Actuating, Controlling, and Evaluating), program pengabdian masyarakat ini dilakukan melalui platform daring berupa workshop. Program ini mendapat respon positif dari 50 peserta guru dan calon guru bahasa yang bergabung. Mereka juga menyadari pentingnya masalah ini untuk mencegah punahnya budaya lokal. Mengintegrasikannya dengan teknologi ke dalam pengajaran bahasa bisa menjadi alternatif yang bisa dilakukan. Para siswa juga dapat mengenali budaya lokal mereka sendiri dengan mendapatkan beberapa teks yang berisi warisan budaya sambil belajar bahasa. Sementara itu, guru juga dapat berperan sebagai promotor budaya melalui materi ajar yang dibawanya ke dalam kelas. Dengan demikian, konservasi budaya dapat dilakukan oleh kedua pihak, yaitu guru dan siswa sebagai generasi muda.
Numerical Modeling for Region of Freshwater Influence by Han River Discharge in the Yeomha Channel, Gyeonggi Bay
Authors: Lee Hye Min , Song Jin Il , Kim Jong Wook , Choi Jae Yoon , Yoon Byung Il , Woo Seung-Buhm
Published: August 2021

This study estimates the region of freshwater influence (ROFI) by Han River discharge in the Yeomha channel, Gyeonggi Bay. A 3-D numerical model, which is validated for reproducibility of variation in current velocity and salinity, is applied in Gyeonggi Bay. Distance of freshwater influence (DOFI) is defined as the distance from the entrance of Yeomha channel to the point where surface salinity is 28 psu. Model scenarios were constructed by dividing the Han River discharge into 10 categories (200~10,000 m3/s). The relation equation between freshwater discharge and DOFI was calculated based on performing a non-linear regression analysis. ROFI in Yeomha channel expands from the southern sea area of Ganghwa-do to the northern sea area of Yeongheung- do as the intensity of Han River discharge increases. The discharge and DOFI are a proportional relationship, and the increase rate of DOFI gradually decreases as discharge increases. Based on the relation equation calculated in this study, DOFI in the Yeomha channel can be estimated through the monthly mean Han River discharge. Accordingly, it will be possible to respond and predict problems related to damage to water quality and ecology due to rapid freshwater runoff.
Numerical Analysis of Modified Seabed Topography Due to the Presence of Breakwaters of Varying Reflection Characteristics using Physics-based Morphology Model [SeoulFoam]
Authors: Cho Yong Jun
Published: August 2021

Numerical simulations were implemented to look into the modified seabed topography due to the presence of breakwaters of varying reflection characteristics. The numerical model was composed of OlaFlow, an OpenFoam-based tool box, and a physics-based morphology model [Seoul Foam]. In doing so, the interaction between the seabed, which undergoes deformation due to siltation and scouring, and the incoming waves was described using Dynamic Mesh. The rubble-mound, vertical, and curved slit caisson breakwaters with varying reflection characteristics resulted in standing waves that differ from each other, shown to have a significant influence on the seabed topography. These results are in line with Nielsen’s study (1993) that sands saltated under the surface nodes of standing waves, where the near-bed velocities are most substantial, convected toward the surface antinodes by boundary-layer drift. Moreover, the crest of sand waves was formed under the surface antinodes of standing waves, and the trough of sand waves was formed under the surface antinodes. In addition, sand wave amplitude reaches its peak in the curved slit caisson with a significant reflection coefficient, and the saltation of many grains of sand would cause this phenomenon due to the increased near-bed velocity under the nodes when the reflection coefficient is getting large.

Endocytosis is an important process by which many signaling receptors reach their intracellular effectors. Accumulating evidence suggests that internalized receptors play critical roles in triggering cellular signaling, including transforming growth factor β (TGFβ) signaling. Despite intensive studies on the TGFβ pathway over the last decades, the necessity of TGFβ receptor endocytosis for downstream TGFβ signaling responses is a subject of debate. In this study, mathematical modeling and synthetic biology approaches are combined to re‐evaluate whether TGFβ receptor internalization is indispensable for inducing Smad signaling. It is found that optogenetic systems with plasma membrane‐tethered TGFβ receptors can induce fast and sustained Smad2 activation upon light stimulations. Modeling analysis suggests that endocytosis is precluded for the membrane‐anchored optogenetic TGFβ receptors. Therefore, this study provides new evidence to support that TGFβ receptor internalization is not required for Smad2 activation.

Latest developments in thin‐film electronics have put skin electronics in the limelight. Integration of multiple skin sensors and wireless power transferring ability are cardinal components for continuous acquisition of the human signals, enabling higher level of applications in wearable healthcare and AR/VR devices. Skin sensor is considerably influenced by target body parts and users where it is attached, and thus face various design adjustments for the best performance. However, most skin electronics using conventional fabrication methods have a fixed design for specific targets and users only and face great challenge when they need design changes, for it has to re‐initialize entire fabrication process even for the simplest design modification. Here, in situ and in operando adaptation (SOA) is presented, a revolutionary customizable electronic fabrication platform that allows simultaneous evolvable design modification and addition of new functionality to original skin electronics while they are in operation on a human skin. SOA renders immediate response to various user specifications possible, offering concurrent customization for various wearable and wireless applications including human physiology/motion sensors. Furthermore, SOA offers simultaneous impedance optimization in different body parts and users which enables on‐skin wireless power supply. These findings will prove a boon to the development of customizable wearable skin‐like electronics.

Dual‐atom catalysts have the potential to outperform the well‐established single‐atom catalysts for the electrochemical conversion of CO2. However, the lack of understanding regarding the mechanism of this enhanced catalytic process prevents the rational design of high‐performance catalysts. Herein, an obvious synergistic effect in atomically dispersed Ni–Zn bimetal sites is observed. In situ characterization combined with density functional theory (DFT) calculations reveals that heteronuclear coordination modifies the d‐states of the metal atom, narrowing the gap between the d‐band centre (εd) of the Ni (3d) orbitals and the Fermi energy level (EF) to strengthen the electronic interaction at the reaction interface, resulting in a lower free energy barrier (ΔG) in the thermodynamic pathway and a reduced activation energy (Ea) as well as fortified metal–C bonding in the kinetic pathway. Consequently, a CO faradaic efficiency of >90% is obtained across a broad potential window from −0.5 to −1.0 V (vs RHE), reaching a maximum of 99% at −0.8 V, superior to that of the Ni/Zn single‐metal sites.

Improving power conversion efficiency (PCE) is important for broadening the applications of organic photovoltaic (OPV) cells. Here, a maximum PCE of 19.0% (certified value of 18.7%) is achieved in single‐junction OPV cells by combining material design with a ternary blending strategy. An active layer comprising a new wide‐bandgap polymer donor named PBQx‐TF and a new low‐bandgap non‐fullerene acceptor (NFA) named eC9‐2Cl is rationally designed. With optimized light utilization, the resulting binary cell exhibits a good PCE of 17.7%. An NFA F‐BTA3 is then added to the active layer as a third component to simultaneously improve the photovoltaic parameters. The improved light unitization, cascaded energy level alignment, and enhanced intermolecular packing result in open‐circuit voltage of 0.879 V, short‐circuit current density of 26.7 mA cm−2, and fill factor of 0.809. This study demonstrates that further improvement of PCEs of high‐performance OPV cells requires fine tuning of the electronic structures and morphologies of the active layers.

Development of industrially relevant thin‐film deposition processes is a necessity for upscaling the perovskite solar cell technology to commercial product‐level. This work reports on a sequential deposition method for state‐of‐the art triple cation perovskite by slot‐die coating. During this two‐step process, first, a layer of lead iodide mixed with cesium iodide is deposited, followed by applying the organic cations on top, inducing conversion to perovskite during a second slot‐die coating step. By carefully tuning the ink composition and the deposition parameters, uniform perovskite layers of 5 × 10 cm2 are obtained. Power conversion efficiencies up to 19% for small laboratory solar cells adopting a planar device configuration and up to 15.2% for mini‐modules with an aperture area of 12 cm2 are presented. These values are among the highest efficiencies achieved in the literature for slot‐die‐coated perovskite.

Liquid gates can provide an effective method to control the release of substances. However, the size of liquid gates and the control methods limit their broad applications. The controllable large deformation of liquid metals (LMs) makes it possible to be used in liquid gate design with simple actuation methods. Here an LM gate that can be easily driven under moderate conditions is proposed, on demand opening at mild electrical voltage (2–5 V) and closing at an oscillating mechanical force (≈0.05 N) in a wide range of pH (2–12). The gating mechanism relies on the large surface tension alteration at these conditions, which directly changes the shape of the LM from a flat film to a contracted meniscus to one side of the copper gate‐frame. As demonstrated, this gate can be applied to release substances such as liquid (ink), biomolecule (insulin) by free diffusion. Moreover, single‐channel and multichannel gates can be realized for high throughput control. The biocompatibility of the whole gate is also proved by cytotoxicity assays. Above all, a novel LM gate is offered with simple structure and easy control, which may bring inspiration to applications in controlled substance release and separation.

Perovskite light‐emitting devices (peLEDs) have recently gained widespread attention as candidates for next‐generation display technologies. Red and green peLEDs have achieved over 20% external quantum efficiency (EQE), however blue peLEDs still lag behind. One proposed solution for improving the performance of blue peLEDs has been doping the perovskite films with metal ions, ostensibly to passivate surface trap sites and improve the EQE. Despite a few recent reports, however, the many roles of the metal ion dopants have not yet been fully explored. Here improvements in the EQE and spectral stability of quasi‐2D perovskites, often called 2D/3D or layered perovskites are reported. CsPbBr3−xClx sky‐blue emitting peLEDs, with a maximum EQE of 7.5%, and color stable spectra at high applied voltages are achieved, via doping with divalent metal ions at concentrations of 0.5 to 10%, by mole ratio. After screening several candidates, two metal ions are identified, Mn2+ and Mg2+ that are particularly effective, as compared with PEA‐based quasi‐2D control devices. Then these examples are used to study the effect of metal ions more generally on the film morphology, the hole transport layer's conductivity, the trap density, and the energy funneling dynamics, all of which strongly influence the device performance.

Published: August 2021

The mechanisms underlying homogeneous fluidization of Geldart A particles have long been debated. Recent experiments shed fresh insights that both a solid‐like and a fluid‐like state exist. Herein, 3D computational fluid dynamics‐discrete element method simulations with the incorporation of interparticle van der Waals forces were performed for five typical Geldart A particles to investigate the bed structure in the homogeneous fluidization regime. Simulation results reproduce the existence of the solid‐like and fluid‐like states, showing that in the solid‐like state, particles have enduring and strong interparticle van der Waals forces that stabilize the bed to keep the bed stationary; while in the fluid‐like state, the interparticle van der Waals forces are dominated by the drag force, and particles show global circulation. Both interparticle van der Waals forces and friction are found to be necessary for the existence of the solid‐like state, and increasing the former has an effect to widen the solid‐like state.
Permselectivity improvement of PEBAX® 2533 membrane by addition of glassy polymers (Matrimid® and polystyrene) for CO2/N2 separation

Published: August 2021

Two series of novel blend membranes based on poly(ether‐block‐amide) (PEBAX® 2533) and 5 and 10 wt% of two glassy polymers (Matrimid® and polystyrene [PS]) were prepared using a new mixed solvent with a low boiling point for CO2/N2 separation. Fourier‐transform infrared spectroscopy, field emission scanning electron microscopy, and X‐ray diffraction analyses were used to characterize the samples. A decrease in membrane crystallinity was observed by the addition of glassy polymers. The gas permeability measurements were performed to obtain CO2/N2 permselectivity of membranes. The maximum performance was found for the membrane with 5 wt% Matrimid content, for which CO2 permeability and CO2/N2 selectivity increased by 21% and 76%, respectively. Three permeation models were used to predict the CO2 permeability of blend membranes. The Maxwell model showed acceptable coincidence with the experimental data at 5 wt% content of the glassy polymer. For 10 wt% content of glassy polymer, the Lewis‐Neilson model showed the most accurate predictions for CO2 permeability. A method for quantitative comparison of membrane performance was also proposed by defining the geometric closeness to the Robson upper bound limit. Finally, it was found that an increase in the feed pressure improved the membrane performance at high pressures.
