Tradisi dan adat-istiadat yang ada di Indonesia sangatlah beragam, budaya yang ada di indonesia adalah salah satu peninggalan sejarah yang harus kita lestarikan saat ini karena kehidupan yang menjadi lebih modern sedikit demi sedikit mengikis keberadaan budaya lokal. Dalam Sejarahnya, Indonesia merupakan masyarakat dengan banyak suku dan budaya yang memiliki kearifan lokal yang dilestarikan oleh masyarakatnya. Petik Laut menjadi salah satu tradisi yang ada di indonesia yang saat ini masih dilakukan tepatnya berada di Kecamantan Puger Kabupaten Jember. Masyarakat puger beranggapan bahwa hasil dari alam sekitarnya merupakan sumber daya dan kunci dari kesejahteraan hidupnya. Maka dari itu, hal ini membuat beberapa masyarakat yang tinggal di daerah pesisir memiliki tradisi yang dilakukan sebagai bentuk rasa syukur dan terima kasih dikarenakan sumber daya alam yang mereka dapatkan dari laut dapat memenuhi kebutuhan hidup mereka. Masyarakat pesisir biasanya menggunakan ritual yang sudah menjadi tradisi turun - temurun sebagai ungkapan rasa syukur tersebut. Selain itu tradisi yang dilakukan oleh masyarakat pesisir ini juga sebagai doa atau harapan supaya hasil tangkapan ikan berlimpah dan juga mendapatkan keselamatan. Kegiatan ini dilaksanakan pada saat Muharram atau Suro. Tradisi petik laut ini merupakan penggabungan dari kearifan lokal dan agama. Dalam tradisi Petik Laut terdapat doa - doa dan pembacaan ayat suci Al -Quran sebelum pada akhirnya sesaji dilarungkan ke laut.

Model reference adaptive control for nonlinear time‐varying hybrid dynamical systems
Authors: L'Afflitto Andrea 
Published: May 2023

SummaryThis paper presents the first model reference adaptive control system for nonlinear, time‐varying, hybrid dynamical plants affected by matched and parametric uncertainties, whose resetting events are unknown functions of time and the plant's state. In addition to a control law and an adaptive law, which resemble those of the classical model reference adaptive control framework for continuous‐time dynamical systems, the proposed framework allows imposing instantaneous variations in the reference model's trajectory to rapidly steer the trajectory tracking error to zero, while retaining the closed‐loop system's ability to follow a user‐defined signal. These results are enabled by the first extension of the classical LaSalle–Yoshizawa theorem to time‐varying hybrid dynamical systems, which is presented in this paper as well. A numerical simulation shows the key features of the proposed adaptive control system and highlights its ability to reduce both the control effort and the trajectory tracking error over a classical model reference adaptive control system applied to the same problem.

AbstractDeveloping high‐performance oxygen evolution reaction (OER) catalysts are critical for the practical application of many electrochemical energy devices. In this study, taking layered perovskite oxide thin films as the model system, it is demonstrated that the OER pathway can be effectively shifted by activating lattice oxygen, leading to strongly enhanced intrinsic activity. The OER performance of Ruddlesden‐Popper (RP)‐phase cobaltite is significantly enhanced as Sr doping at the A site increases, which is attributed to the shift of the reaction pathway from adsorbate evolution mechanism (AEM) to lattice oxygen‐mediated mechanism (LOM). Advanced spectroscopic techniques and density functional theory calculations reveal that the Sr dopant effectively facilitates oxygen ligand hole formation, charge transfer from the oxygen sites, and the formation and migration of oxygen vacancy, hence promoting lattice oxygen to participate in surface reactions. The results provide critical insight into the role of oxygen activity and offer a potential way for constructing highly active electrocatalysts.
Azobenzene Functionalized Organic Covalent Frameworks: Controlled Morphologies and Photo‐Regulated Adsorption

Published: May 2023

AbstractCovalent organic frameworks (COFs) containing azobenzene building blocks carry great potential for use in intelligent storage, separation, chemical sensing, and catalysis due to their intriguing photo‐responsiveness. However, azobenzene units are often exploited as the linkers to form the framework of COFs, thereby restricting their molecular motion and photoisomerization. Herein, a simple yet robust template‐free solvothermal strategy is reported to yield azobenzene‐dangled COFs (Azo‐COFs) with their azobenzene moieties suspending within the pores. The crystallinity, specific surface area, and morphology of Azo‐COFs can be conveniently tailored by changing the ratio of amine to aldehyde monomers. Notably, the Azo‐COFs provide sufficient free space for the reversible trans‐to‐cis isomerization of the dangled azobenzene units inside the pores, thus reversibly regulating surface wettability of Azo‐COFs. The adsorption capacity of Azo‐COFs toward organic dye molecules is increased by 3.7‐fold when irradiated with ultraviolet light, which can be ascribed to the intelligent closing/opening of molecular gates rendered by photoisomerization of azobenzene moieties. As such, the ability to photoregulate the adsorption of Azo‐COFs highlights their significance in functioning as smart porous nanomaterials for applications in cargo release, molecular sieves, ion transport, energy conversion systems, and environmental remediation.

AbstractConductive hydrogels (CHs) are regarded as one of the most promising materials for bioelectronic devices on human‐machine interfaces (HMIs). However, conventional CHs cannot conform well with complex skin surfaces, such as hairy or wrinkled skin, due to pre‐formation and insufficient adhesion; they also usually lack antibacterial abilities and require tissue‐harm and time‐consuming preparation (e.g., heating or ultraviolet irradiation), which limits their practical application on HMIs. Herein, an in situ forming CH is proposed by taking advantage of the PEDOT:PSS‐promoted self‐polymerization of zwitterionic [2‐(methacryloyloxy)ethyl]dimethyl‐(3‐sulfopropyl) (SBMA). The hydrogel is formed spontaneously after injection of the precursor solution onto the desired location without any additional treatments. The as‐prepared hydrogel possesses excellent elasticity (elastic recovery >96%), desirable adhesive strength (≈6.5 kPa), biocompatibility, and intrinsically antibacterial properties. Without apparent heat release (<5 °C) during gelation, the hydrogel can form in situ on skin. Additionally, the obtained hydrogel can establish tight contact with skin, forming highly conformal interfaces on hairy skin surfaces and irregular wounds. Finally, the in situ forming hydrogels are applied as conformal epidermal electrodes to record stable and reliable surface electromyogram signals from hairy skin (with high signal‐to‐noise ratio, SNR ≈ 32 dB) and accelerate diabetic wound healing under electrical stimulation.

AbstractThe electron transport layer (ETL) plays a crucial role for efficiency and stability of perovskite solar cells (PSCs). As a promising low‐temperature ETL, tin oxide still requires complicated surface chemical decoration or heat‐treatments to further passivate the defects and adjust band energy level to improve the optoelectronic performance of the device. Herein, a novel and efficient strategy is developed for the solution prepared annealing‐free SnO2 ETL for PSCs. Through simple electrochemical regulation, the elemental composition, valence ratio of Sn, concentration of oxygen vacancies, hydroxyl groups, and dopant ions are precisely modified with the optimized the energy band, reduce the defect density, and enhance high carrier transport for PSCs. Thus, an increase of power conversion efficiency (PCE) from 21.6% to 24.7% and a high VOC of 1.19 V is obtained. The modified devices maintain 95% of the initial PCE after 2000 h of storage, and 80% of the initial PCE after 900 h of aging in an atmospheric environment at 75 °C and RH 20 ± 5%. Moreover, the perovskite solar module based on the as made SnO2 achieve a high PCE of 21.3%.

AbstractThe growth of disordered lithium dendrite and the notorious reaction between Li and electrolyte hamper the practical application of Li metal batteries (LMBs). Herein, an artificial solid electrolyte interphase (ASEI) constructed by a nitro‐functionalized covalent organic framework (NO2‐COF) is designed to regulate Li+ deposition and stable Li anodes. Strong electron‐withdrawing nitro groups can gather the surrounding electrons of connected monomer by the donor‐acceptor (D‐A) effect, thus regulating the electron structure of the covalent organic framework (COF) and constructing a specific cation‐oriented channel. The uniform Li+ deposition and inhibition of Li dendrites are achieved under such a high‐selective Li+ transportation channel and regulated surface electric charge. In addition, the nitro can also be reduced to NO2− and further react with Li to produce high ionic‐conductivity Li3N and LiNxOy during the charging/discharging, which contributes to the migration of Li+. As a result, NO2‐COF‐modified symmetrical batteries realize an ultra‐long cycling life of more than 6000 h under a current density of 5 mA cm−2 compared to bare Li and TpBD‐COF/Li (without nitro). The full cells coupled with LiFePO4 stably cycle 1000 times with a capacity retention of 91%. Hence, effectively optimizing electron structure by the donor‐acceptor (D‐A) effect provides a better platform to elevate the performance of LMB.
Multielectron Conversion: Peculiar Transition Metal Sulfides with Mixed Vulcanized States toward High‐Capacity Metal‐Ion Storage

Published: May 2023

AbstractTransition metal sulfides with mixed vulcanized states (TMS‐mVs) possess tremendous potential to realize highcapacity, superior redox reactions, and structural reversibility for metal‐ion (Mn+) storage owing to their multielectron reactions caused by the simultaneous participation of transition metal (TM) cations and S22−anions as well as multifarious TM or S valence states. Here, recent advances are systematically introduced regarding the mainstream TMS‐mVs that can be applied to Mn+storage. These TMS‐mVs can be divided into two categories of TMS, those with mixed sulfur‐valence states (TMS‐mSs) and those with mixed metal‐valence states (TMS‐mMs). It is found that TMS‐mV anodes mainly experience three reaction mechanisms, inculding insertion‐accompanied conversion, insertion, and conversion reactions. During the reversible charge process, Li2S is possibly oxidized into polysulfides or even S. TMS‐mVs have the ability to transfer more electrons than other homogeneous TMSs. TMS‐mS anodes usually present higher theoretical specific capacities than TMS‐mM anodes. In these TMS‐mV anodes, Mo‐based, V‐based, and Co‐based TMS‐mM anodes exhibit good electrochemical reversibility, Ni‐based TMS‐mM anodes exhibit moderate electrochemical reversibility, and Fe‐based TMS‐mM and TMS‐mS anodes exhibit poor electrochemical reversibility. The strategies for enhancement of their electrochemical performance are classified into composite, coating, nanostructure, heterointerface, and lattice engineering.

AbstractPlastic/ductile inorganic van der Waals (vdW) thermoelectric semiconductors offer transformative advantages for high‐performance flexible thermoelectric devices, which can displace the self‐charge system of wearable electronics. However, the chemical origin of their plasticity remains unclear. Here, it is reported that the exceptionally large plastic strain of the bulk SnSe2 crystal results from its polytype conversion under an external force. The SnSe2 single crystal consists of a large‐period polytype with 18R low‐symmetry structure rather than the trigonal and hexagonal‐phase that are frequently observed in the polycrystalline specimen. In situ applied pressure to the specimen drives a phase transition from low to high‐symmetry, that is, from 18R to 4H, and finally to 2H‐SnSe2. First principle calculations corroborate that the dynamic phase transition is a pressure‐activated process and only 15 MPa pressure erases their energy gaps, consistent with experimentally measured strain–stress curves. This dynamic phase transition results in superior and near isotropic plasticity along the direction parallel and perpendicular to the cleavage plane.
