The Effect of Hull-Ice Friction Coefficient on the Resistance of Icebreaking Ships
Authors: Spencer Donald
Published: September 2022

Using empirical data from model test with 5 similar hull forms, a relationship between ice resistance and friction coefficient is developed. The techniques used in interpreting the model data and normalizing to a common basis are also presented. These include breaking the total resistance into four components; ice breaking, submergence, clearing and open water, and scaling each individually to a common basis. In total, 187 data points were used representing seven different hull-ice friction coefficients. The results show a doubling of ice resistance as the hull-ice friction goes from 0. 05 for a new ship to 0.10 for a ship with a hull in poor condition. Full-scale data for the Canadian Coast Guard R­Class icebreakers is also presented showing a deterioration in icebreaking performance over a ten year period.
Design and Application of Force Dynamometers
Authors: Chakrabarti Subrata K. , Libby Alan R.
Published: September 2022

In model basin testing it is a common practice to measure both the global and local loads on offshore and mari.ne structures. The purpose of this paper is to describe the design and application of a variety of load cells for the measurement of these loads under a simulated wave environment. Several specific examples are chosen for both marine and offshore structures and the load cell design for these structures is discussed. In this regard, it should be noted that the distinction between the two types of structures is made to differentiate the in-place offshore structures from the floating ocean-going structures. The model structures chosen are jacket type structures and submarines. The load cells that are included have application in the measurement of both local and global loads on these structures. The calibration method and calibration results are given. Checks on the accuracy of measurements are often made which are illustrated. Anomalies present in any of these data are discussed. The load cells chosen for the discussion in this paper are considered to have a wide variety of applications.
Wave Generating Software at the U.S. Naval Academy
Authors: Zseleczky John J.
Published: September 2022

Since the 23rd ATTC in 1992, the U.S. Naval Academy Hydromechanics Laboratory (NAHL) has replaced and updated all of the computer hardware and software used to drive its three wavemakers. Until last year, some of the original equipment that was installed in the mid 1970's was still in use. The old system was cumbersome to use by today's standards, but was capable of generating very good waves. Eventually, the computer hardware became unreliable and had to be replaced. This paper describes the replacement system that was put together at NAHL. The new system is based on the old one, but wherever possible uses “off-the-shelf” components that can be easily replaced as technology advances. The paper gives an overview of the hardware and software used to drive the wavemakers and describes the types of waves that can be generated with the new system. Each time new wavemaker drive signals ar. e created, decisions must be made about digitization rates, data analysis frame lengths, etc. The paper discusses tradeoffs involved in selecting those parameters and their impact on the waves produced. Also, some of the subtleties involved in creating wavemaker drive signals are mentioned; for instance, the splicing of drive signal frames when the endpoints don't match up. Finally, details are given on a procedure used to adjust and refine drive signals so that the measured wave spectrum more closely resembles the desired spectrum.

The Naval Surface Warfare Center, Carderock Division (NSWCCD) with major facilities at Carderock and Annapolis, Maryland and Philadelphia, Pennsylvania, is currently pursuing certification of a Quality Management System under International Standard ISO 9001. Three pilot programs within the Division are involved. One of these pilot programs is the Full Scale Trials Branch of the Hydromechanics Directorate (David Taylor Model Basin) located in Carderock, Maryland. The other two pilot programs are the Submarine Sail Systems Department and the Vibration Monitoring and Trending Section. Both of these pilot programs are part of the Machinery In-Service Engineering Directorate located at the Naval Ship Systems Engineering Station (NAVSSES) in Philadelphia, Pennsylvania. The Full Scale Trials Branch conducts Hydrodynamic Performance Trials on surface ships and submarines of the US. Navy using model predictions provided by other branches within the Hydromechanics Directorate. The full-scale data is used to validate the predictions and is then provided to the model groups for post-trial correlation. The goal of the Hydromechanics Directorate is to certify a quality management system that is in compliance with ISO 9001 Standard 1994 and which encompasses the processes of model testing, ship powering predictions, full-scale testing, validation of predictions, and full scale/model correlation.
Recent Advances in Wave Energy Utilization
Authors: McCormick Michael E. , Hayden Dan
Published: September 2022

After many decades of study, two wave energy conversion systems have been shown to be the most effective in producing either electricity or potable water at remote location, such as the over 100,000 inhabited islands of the world. Those systems are the McCabe Wave Pump (MWP) and the Backward Bent Duct Barge (BBDB). Both of these are floating systems with well defined missions for remote locations. The BBDB is primarily designed to provide electricity, while the MWP's primary mission is to provide potable water. Both systems are resonant systems, in that they are designed to operate most efficiently in the neighborhoods of specific wave periods. In random seas, the operational ranges of each are within the half-power bandwidth of the center band resonant periods. The BBDB is an oscillating water column system in which a horizontal column of water, with its mouth facing aft and its internal free,-surface facing upward through a 90° bend at the bow of the floating structure, excites a pneumatic turbogenerator above the internal free-surface by the wave-induced motions of the water column. In other words, the water column acts as a flexible piston. The MWP is a mechanical-hydraulic system which provides high-pressure, pre-treated water to reverse osmosis desalination systems by the motions of hinged barges. The BBDB is now operational in Japan and China, while a prototype of the MWP is now deployed in the Shannon Estuary in Ireland. The operations of these two systems, as related to the hull dynamics, are discussed.

U. S. Navy Ship-Model Powering Correlation 1982 to 1995
Authors: Karafiath Gabor
Published: September 2022

The idea of an adjustment to model test procedures in order to improve ship powering predictions was initially introduced many years ago as a roughness allowance because it was recognized that the basic methodology involved in predicting power from model tests yields powering estimates for ships whose hulls are smooth. Thus an increment to the smooth ship resistance was added to account for the ships’ roughness and this increment was called the roughness allowance. Later on it was recognized that the difference between the predicted and measured power was due to roughness as well as other factors and the concept of a correlation allowance coefficient designated by the symbol CA was developed for engineering and design purposes in order to obtain the most accurate ship powering predictions. The value of the correlation allowance for a specific ship is determined from the analysis of ship and model powering data. The correlation allowances for specific ships forms a database or experience factor that helps guide the powering prediction for a proposed new design. In the years following WWII, the U.S. Navy ships still had riveted hull plating or a combination of riveted and welded plating and many ships used a hot plastic finish which resulted in a relatively rough ship hull. Paints with smoother finishes were just being introduced. Hadler et al [1] discussed the impact of paint type and construction method on CA and showed that in the 20 years leading up to 1960 there was a general decrease in the CA. It was common practice at the time to assume a constant value of CA equal to 0.0005 for all ship sizes. By the early 1980' s the common ship construction practice was an all welded ship with a relatively smooth paint finish such as the Navy Milspec vinyl. The Navy ship-model correlation data was reassessed and summarized by Hagen et al [2]. The earlier data with hot plastic 205 were purposefully disregarded and a correlation allowance instruction which is a function of ship length, see Fig. 1 , was issued by Naval Sea Systems Command (NAVSEA) [3] and defined for U.S. Navy powering predictions according to the standard David Taylor Model Basin (DTMB) powering prediction method documented by Grant and Wilson [4] . The primary purpose of this paper is to examine the ship-model correlation data gathered since the early 1980' s and to see if there is a need to modify the NAVSEA CA curve. Other purposes are to examine the accuracy of the RPM prediction using the David Taylor Powering Prediction method, and to discover if there are any ship or model characteristics in addition to length that could influence the selection of CA.

The series consists of 9 models with a systematic variation of the L/B ratio with values 2.5, 3.0 and 3.5, and three deadrise angles P of 12°, 18° and 24°. The weight displacement A, Lex; and thrust line were also varied systematically, giving a total of 210 test conditions at 10 velocities each. This document describes the series design and testing and the results obtained. Initial findings are outlined as well as some recommendations for future research.
Resistance Characteristics of Six Inshore Fishing Vessels in the Preplanning Regime
Authors: Lacy G. E.
Published: September 2022

Models of four Cape-Island style, and one Maine-type inshore fishing vessels were towed in calm water in the Centre for Marine Vessel Design and Research's (CMVDR's) towing tank at speeds up into the preplanning regime. The vessels have some of the characteristics of high speed displacement/semiplaning hulls, but are more typical of displacement hull design in other respects. Full scale resistance, sinkage, and trim characteristics were established at several LCG's and displacements. The data were compared and non-dimensional resistance curves plotted. An attempt was made to graphically 'collapse' the resistance data to a single line, and in so doing it was found that the resistance depends strongly on displacement and waterline length to beam ratio. Regression analyses were performed on the data at several speed ranges separately for the purpose of producing resistance prediction equations. The results are compared against published material.
A Model Experiment Technique for Predicting the Capsizing of Damaged RO-RO Ferries
Authors: Molyneux David , Cumming David
Published: September 2022

Pioneering model experiments to study the danger of wave action flooding the deck of damaged RO-RO ferries were carried out by Bird and Browne in the 1970's. Following the loss of the Herald of Free Enterprise in 1987 there was renewed interest in the subject, with studies in the United Kingdom and Denmark. Following this work, a further series of experiments was carried out in Canada, at the Institute for Marine Dynamics (IMD), with the prime objective of investigating the effectiveness of the SOLAS 90 regulations. The experiments at IMD used a two-dimensional prismatic model to understand the process and provide data for validating numerical simulations. A key feature in the experiments carried out at IMD was the desire to measure the volume of water on the deck at all times during the flooding and capsize process. The design of the model, the data collected during the experiments and the methods of analysis are discussed in general terms. Finally recommendations are made for improving the techniques for use in future studies.
Victim-focused political apology predicts political support via perceived sincerity, trust and positive emotional climate: The case of the 2018 bushfire in Attica
Authors: Gkinopoulos Theofilos
Published: September 2022

Political leaders tend to apologize for wrongdoings. This study focuses on a disaster that occurred on July 2018 in east Attica, Greece, where wildfires destroyed houses and left dozens of people dead. Two pilot studies and one main study were conducted testing perceptions of apology as sincere, perceived trust, positive emotional climate and participants’ support towards the governmental policies. Participants (N = 180 for the two pilot studies, N = 222 for the main study) were recruited from the disaster zone of east Attica. The focus is on two key forms of political apology, a self or offender-focused apology and a self-other or victim-focused apology. Participants were randomly assigned to one of the conditions equivalent to each of the two forms of apology, that is either in a victim-focused apology condition or an offender-focused apology, or a control condition, where a neutral image was shown to participants. Results showed a positive association between victim-focused apology, compared to offender-focused apology, and political support towards the government via increased perceived sincerity, trust and positive emotional climate. Political and psychological implications related to different forms of public apologies are discussed.

Published: September 2022

Operacije v področju prsnega koša spadajo med najbolj boleče operacije, kjer prepletanje operacijskega polja in dihalne poti še dodatno prispeva k nastanku in vzdrževanju bolečine po posegu. T. i. pooperativno bolečino je potrebno lajšati, ker povečuje tveganje za zaplete, kot so pljučne atelektaze, pljučnica, daljša hospitalizacija, kasneje pa tudi razvoj kroničnega bolečinskega sindroma. Pristop k lajšanju bolečine po operacijah v prsnem košu je tri stopenjski. Vključuje seznanitev z možnostmi za lajšanje bolečine med in po operaciji v sklopu priprave na poseg, čim pogostejšo uporabo področnih tehnik za lajšanje bolečine med operacijo ter multimodalni pristop za lajšanje bolečine v obdobju po posegu za zmanjšanje celokupne porabe opioidov. V sklopu tega so se tradicionalno uveljavljeni torakalni epiduralni analgeziji v zadnjem desetletju pridružile manj invazivne področne analgetične tehnike, kot so paravertebralni blok, blok pod mišico erector spinae, retrolaminarni blok, blok serratus anterior in interkostalni blok. K razvoju teh tehnik je prispevala predvsem uporaba ultrazvoka, vedno večja uporaba zdravil proti strjevanju krvi ter uvajanje manj invazivnih kirurških tehnik, ki zahtevajo prilagoditev vodenja anestezije v smislu uporabe čim manj invazivnih področnih analgetičnih tehnik. Učinkovito lajšanje bolečine med in po operaciji je ključno za preprečitev kroničnega bolečinskega sindroma, ki bolnikom močno poslabša kakovost življenja, zdravstvenemu sistemu pa naloži dodatne stroške zdravljenja. Pregledni članek bo prikazal trenutne možnosti za lajšanje bolečine med in po operacijah v prsnem košu s poudarkom na vrsti in mehanizmu delovanja novejših področnih analgetičnih tehnik.

Authors: Masinading Zyril Mae B. , Gaylo Derren N.
Published: September 2022

The benefits of differentiated scaffolding strategies on boosting academic performance and confidence in Mathematics learners were studied in this paper. Quasi-experimental research was conducted at a state university’s Secondary School Laboratory in the Philippines. It involved sixty Grade 8 learners, 30 from the control group and 30 from the experimental group. A panel of specialists assessed developed lessons on triangle congruence topics and the academic performance test and confidence scale. The developed lesson, test, and scale were improved after the panel of experts’ comments and suggestions were considered. The instruments were pilot tested and came out reliable; the academic performance test had a Cronbach alpha of 0.807, while the confidence scale in Mathematics had a Cronbach alpha of 0.810. In addition, the mean, standard deviation, One-way Analysis of Covariance (ANCOVA), and Pearson Product Moment Correlation were used to analyze the data. The findings demonstrated that when learners were taught using differentiated scaffolding strategies, their academic performance significantly increased at the Fairly Satisfactory level. However, when they were taught using conventional teaching strategies, their academic performance remained at Did Not Meet Expectations. The performance outcomes of both groups were significantly different. Also, there was no significant difference in learners’ confidence between the two groups when compared. Furthermore, there was a significant link between academic performance and confidence in Mathematics among students taught using differentiated scaffolding methodologies. Thus, concerns about increasing learners’ mathematical literacy may be addressed with differentiated scaffolding strategies.

Published: September 2022

In response to shifting consumer demands, food packaging's conventional function is continuing to change. Consumer desire for healthier, safer and good quality meals with longer shelf-life is one of the current causes that are challenging the food packaging sector to produce new and better technology packaging solutions. Therefore, Active packaging (AP) can be used to satisfy these requirements. The biggest advantage of Active packaging (AP) is less food waste because the items have a longer shelf life. Undoubtedly, active packaging is a great option for a variety of food sector applications. In the upcoming years, the commercial success of active packaging systems should be anticipated as they represent the growth of food packaging in the future. In this review, a summary of active packaging technologies, including oxygen scavenger, moisture scavenger, ethylene absorber, antioxidant-releaser, CO2 emitter, and antimicrobial packaging systems are provided. In particular, reviews of scientific studies emphasizing the advantages of these technologies for certain food products are conducted. However, the development of food nano-packaging is still in its early stage, despite having numerous opportunities to enhance packaging materials and functions. Although, due to the advancements in nanotechnology there might be higher chances of enabling the creation of better active packaging. This article also discusses current breakthroughs in food nano packaging based on active nanoparticles.

Analysis and Comparison of Early Childhood Nutritional Outcomes Among Offspring of Chinese Women Under the Chinese 2021 and US 2009 Gestational Weight Gain Guidelines
Authors: Chen Fangfang , Wang Peng , Wang Jing , Liao Zijun , Zong Xinnan , Chen Yiren , Lai Jianqiang , Zhang Ting , Liu Gongshu , Xie Xianghui
Published: September 2022

Importance

In 2009, the US National Academy of Medicine (NAM) released revised gestational weight gain (GWG) guidelines, which were established primarily for White North American women and may be unsuitable for Asian women. In 2021, the Chinese Nutrition Society (CNS) released its GWG guidelines, but their applicability requires re-examination.

Objective

To compare the differences between the CNS and NAM recommendations for GWG in association with health outcomes in the offspring of Chinese women.

Design, Setting, and Participants

In this bidirectional cohort study, children in China were recruited at age 3 years from 2017 to 2018, with 2 follow-up visits over the next 2 years (between September 2017 and September 2020). Information during pregnancy was retrieved from medical records. Data analysis was performed from October 2021 to January 2022.

Main Outcomes and Measures

GWG was classified as insufficient, appropriate, or excessive according to the CNS and NAM guidelines separately. Children’s height, weight, fat mass, fat-free mass, and percentage of body fat were measured at each visit. Body mass index, fat mass index, fat-free mass index, weighted κ score, risk ratio values, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated.

Results

A total of 3822 children (1996 boys and 1826 girls; mean [SD] age, 3.79 [0.30] years) were enrolled; after exclusions, 3170 term singleton children were recruited and were followed at 4 and 5 years of age. According to the CNS guidelines, the prevalence rates were 14.1% for insufficient GWG, 48.1% for appropriate GWG, and 37.9% for excessive GWG, whereas the rates according to NAM guidelines were 39.7% for insufficient GWG, 37.2% for appropriate GWG, and 23.1% for excessive GWG. The weighted κ value for the classification agreement between the 2 guidelines was 0.530 (95% CI, 0.510-0.550). For the appropriate GWG group, the rates for low nutritional levels did not differ between the 2 guidelines, but the rates for high nutritional levels were significantly lower under CNS guidelines than under NAM guidelines. When the sensitivity, specificity, PPV, and NPV with respect to the mothers who maintained appropriate GWG were used to estimate the nonhigh nutritional status of their offspring, generally higher values based on the CNS guidelines were found compared with those based on the NAM recommendations.

Conclusions and Relevance

These findings suggest that the GWG recommendations promulgated by the NAM are higher than the CNS guidelines, with the latter more suitable for Chinese women.
Internal diffusion and re‐emission of leaked liquid ethyl acetate from mortar materials
Authors: Harashima Hiroshi , Sumiyoshi Eisaku , Ito Kazuhide
Published: September 2022

Assuming the leakage of hazardous liquid chemicals in factories and chemical plants caused by natural disasters or human error, it is important to precisely estimate exposure risk and design appropriate evacuation plans and risk‐reduction measures. The exposure risk of indoor residents to leaked chemicals may be estimated using direct measurements or theoretical/numerical estimations of gas‐phase concentrations. Although mathematical models of gas‐phase concentration in the workplace are essential for predicting exposure concentrations at the design stage, practical models have not yet been fully established. We previously proposed practical numerical models to assess indoor gas‐phase concentration distributions after the accidental leakage of liquid chemicals using liquid toluene as a representative hazardous chemical. In this study, the leakage of liquid ethyl acetate, a commonly used organic solvent, into mortar flooring was reproduced in a small test chamber, and numerical analysis was performed. The results showed that the time history of the chamber exhaust concentration had a sharp peak and differed significantly from that of toluene. Three‐dimensional computational fluid dynamics (CFD) analysis incorporating practical ethyl acetate emission models reproduced the external and internal emission characteristics of leaked ethyl acetate on the mortar material. The models showed reasonable agreement with the experimental data.
Heart drug shows promise for treating AUD
Authors: Knopf Alison
Published: September 2022

There are only three medications approved to treat alcohol use disorder (AUD) — acamprosate, disulfiram, and naltrexone — and none of them works well for everyone. Now that the federal Food and Drug Administration (FDA) has allowed a reduction in drinking, and not abstinence, as an end point for medications to treat AUD (see FDA says alcoholism meds need only eliminate heavy drinking, ADAW Feb. 23, 2015; https://onlinelibrary.wiley.com/doi/10.1002/adaw.30085), other possibilities have opened up. The most recent is spironolactone, a medication for heart problems and high blood pressure.
Heavy alcohol use in women caused increase in suicide mortality
Authors: Knopf Alison
Published: September 2022

A recent study found that rising heavy alcohol use by women — a relatively new phenomenon — has contributed to the increasing sex disparity in the suicide mortality rate. Now, more women than men die from suicide committed while intoxicated. Until 2018, the prevalence of intoxication and suicide mortality had been increasing for both men and women, but women had a notably higher increase in both, according to the study, which looked at data from 2003 to 2018. The increase was particularly significant in women ages 65 and older.

Tailor‐made nanoarchitecturing of highly zincophilic and stable carbon scaffolds is critical but still challenging for Zn‐ion storage with double‐high supercapacitive activity and durability. Herein, a Lewis pair interaction‐guided self‐assembly strategy is reported to design carbon superstructures for activating Zn‐storage sites. The Lewis acid (ferric chloride) and base (p‐phenylenedimethanol) can interact to form organic nanoparticle modules that self‐assemble into well‐defined superstructures constructed from nanotentacle‐building blocks via hydrogen‐bonding and π−π stacking. As‐designed carbon superstructures as aqueous Zn‐ion capacitor cathodes empower the high accessibility of the build‐in zincophilic sites and efficient ion migration with low‐energy hurdles. A charge‐storage mechanism, i.e., opposite charge‐carrier uptake coupled with multielectron redox response, is proposed, which entails the alternate binding of Zn2+/CF3SO3−at active sites and the robust interactions between Zn2+and electronegative carbonyl/pyridine motifs to form O−Zn−N bonds. This unique electrochemistry contributes to high‐rate survivability (100 A g−1), high‐energy density (161.2 Wh kg−1cathode), and ultralong lifespan (400 000 cycles), superior to state‐of‐the‐art Zn‐ion devices in comprehensive performances. This study sheds light on structural engineering for carbon‐based materials toward advanced energy storage.

To fabricate stable neat FAPbI3 perovskite with a pure α‐phase (pure α‐FAPbI3) is important in the field of photovoltaic commercialization because of its better bandgap than its alloying counterpart with cesium (Cs) or methylammonium (MA) cations. In this study, the first vapor deposited pure α‐FAPbI3 thin film solar cell with a power conversion efficiency (PCE) over 20% is achieved by regulating the phase transition process. It is found that under high humidity conditions, a fast phase transition between high‐purity α‐ and δ‐phase FAPbI3 can be realized. Moreover, theoretical calculations interestingly reveal a phase transition shortcut induced by the abnormal volume contraction that is ascribed to the formation of double hydrogen bonds at a certain H2O concentration. Therefore, a high‐humidity post‐treatment strategy is proposed to fabricate α‐FAPbI3 solar cells with a champion PCE of 20.19% (0.1 cm2) and 18.91% (1 cm2), which is currently the highest recorded value in vapor deposited pure α‐FAPbI3 perovskite solar cells. This study helps to redefine the effect of a water molecule on FAPbI3 solar cells. In addition, the demonstrated scaling‐up possibility provides another perspective for fabricating uniform high‐performance pure α‐FAPbI3 perovskite solar cells.

Neural stem cells (NSCs) transplantation has been considered as a promising strategy for the treatment of ischemic stroke. However, the therapeutic prospect is limited by the poor control over the survival, migration, and maturation of transplanted NSCs. Upregulating hypoxia inducible factor (HIF)‐1α expression in stem cells can improve the survival and migration of NSCs grafted for stroke therapy. Functional peptide drugs, which could inhibit endogenous HIF‐1α ubiquitination, might be used to effectively upregulate the HIF‐1α expression in NSCs, thereby to improve the therapeutic effect in ischemia stroke. Herein, a magnetic resonance imaging (MRI)‐visible nanomedicine is developed to codeliver functional peptides and superparamagnetic iron oxide (SPIO) nanoparticles into NSCs. This nanomedicine not only promotes the survival and migration ability of NSCs but also allows an in vivo tracking of transplanted NSCs with MRI. The results demonstrate the great potential of the functional peptides‐complexed multifunctional nanomedicine in boosting the therapeutic effect of stem cell‐based therapy in stroke.

Two key interfaces in flexible perovskite solar cells (f‐PSCs) are mechanically reinforced simultaneously: one between the electron‐transport layer (ETL) and the 3D metal‐halide perovskite (MHP) thin film using self‐assembled monolayer (SAM), and the other between the 3D‐MHP thin film and the hole‐transport layer (HTL) using an in situ grown low‐dimensional (LD) MHP capping layer. The interfacial mechanical properties are measured and modeled. This rational interface engineering results in the enhancement of not only the mechanical properties of both interfaces but also their optoelectronic properties holistically. As a result, the new class of dual‐interface‐reinforced f‐PSCs has an unprecedented combination of the following three important performance parameters: high power‐conversion efficiency (PCE) of 21.03% (with reduced hysteresis), improved operational stability of 1000 h T90 (duration at 90% initial PCE retained), and enhanced mechanical reliability of 10 000 cycles n88 (number of bending cycles at 88% initial PCE retained). The scientific underpinnings of these synergistic enhancements are elucidated.

Published: September 2022

In this work, mode conversion and wavefront shaping by integrating a metallic metasurface on top of a planar waveguide are proposed and demonstrated. The metasurface consists of C‐shaped nanoantennas. By controlling the orientation of each nanoantenna, mode conversion and focusing effect for the cross‐polarized electric fields inside the waveguide are achieved. The design and simulation results of 16 scenarios of wideband transverse‐magnetic to transverse‐electric mode converters with the mode purity up to 98%, and on‐chip lenses at the wavelength of 1550 nm are reported. It is worth noting that the dimension of the devices along the propagation direction is only 9.6 µm. This work manifests the potential application of mode division multiplexing systems and on‐chip optical interconnections based on metasurfaces.
Phase‐Controlled Artificial SiZnSnO/P(VDF‐TrFE) Synaptic Devices with a High Dynamic Range for Neuromorphic Computing

Published: September 2022

Artificial synapses, such as ferroelectric field‐effect transistors, aspire the brain‐like computation in real life and are likely to replace conventional computing methods in the future. Amorphous SiZnSnO (a‐SZTO)‐based ferroelectric field‐effect transistor is fabricated using the organic poly(vinylidene fluoride‐trifluoroethylene) P(VDF‐TrFE) ferroelectric gate insulating layer. First, the ferroelectric properties of P(VDF‐TrFE) are analyzed depending on the crystallization temperature for artificial synaptic transistor applications. The ferroelectricity becomes prominent with the evolution of the β‐phase till 140 °C and degrades thereafter. The a‐SZTO‐based ferroelectric field‐effect transistors employing P(VDF‐TrFE) show anticlockwise hysteresis, typical for a ferroelectric field‐effect transistor. The nonlinearity for the potentiation and depression and the dynamic range is confirmed to be increased with higher β‐phase concentration. The rise in the concentration is related to the elevated thermodynamic stability of the β‐phase between curie temperature and the melting point. Utilizing the parameters obtained from the a‐SZTO‐P(VDF‐TrFE) synaptic transistor, the simulation studies exhibit a high recognition rate of 86.8%, which makes it a promising candidate for artificial intelligence applications.
