Published: June 2022

BackgroundZiziphus jujubaMill. cv. ‘LingwuChangzao’ is a traditional jujube cultivar in northwest China. It is of great significance to explore the weed community composition and environmental characterization for the ecological control and comprehensive management of weeds in jujube orchards. In this article, a total of 37 species were recorded in 40 sample plots (1 m × 1 m). Moreover, fourteen environmental indicators to characterize the spatial locations, climate and soil nutrient characteristics of the plant communities were adopted.MethodologyThrough the two-way indicator species analysis (TWINSPAN) quantity classification and canonical correspondence analysis (CCA) ranking methods, the types of weed communities in the main planting base of jujube ‘LingwuChangzao’ and the main environmental factors affecting the change and distribution of weed types were analyzed.ResultsThe weed communities within the study area were divided into 15 types by the TWINSPAN classification. There were significant differences in soil factors to the species diversity indices of the weed communities, the diversity of weed communities was negatively correlated with available potassium, whereas positively correlated with soil water content. The CCA results showed that community structure and spatial distribution of weed communities were affected by soil water content, total potassium, soil organic carbon, total phosphorus, total nitrogen. Our results can be used as a reference for orchard weed management and provide a theoretical basis for weed invasion control and creating a higher biodiversity in arable land under the background of environmental change.

This study investigated the effectiveness of mass media in the fight against drug abuse among undergraduates of tertiary institutions in Imo State. The study was anchored on the theory of reasoned action and the research design adopted for this study is the survey method. The population consists of 81,000 undergraduates of the select higher institutions in Imo State. A sample size of 382 arrived after the application of the Wimmer and Dominick online sample size calculator. The systematic sampling technique was employed in this study. The percentage method and bar chart were used for analysing the data. The findings revealed that the level of awareness among respondents towards mass media campaigns against drug abuse is moderate. Further findings showed that respondents agreed that mass media efforts have not been effective in reducing the threat of drug abuse among undergraduates in Imo State's tertiary institutions. As a result, it was concluded that mass media campaigns are ineffective in the fight against drug abuse among undergraduates of higher institutions in Imo State, because the campaigns have not succeeded in curbing the menace, as students continue to engage in it, which could be linked to a lack of awareness among these undergraduates. It was recommended that the media intensify their publicity and commitment to drug abuse in order to raise public awareness of the dangers of drug abuse in society. The mass media should be more creative in their content and in some cases, they should employ persuasive communication to be able to influence a good number of youths positively and make them shun drug abuse.
Building effective recommender systems for tourists
Authors: Massimo David , Ricci Francesco 
Published: June 2022

AbstractRecommender systems (RSs) are personalized information search and discovery applications helping users to identify and choose useful items and information. In this paper, we focus on the tourism application scenario and its specific requirements. We discuss a novel RS approach that copes with the specific application constraints of the domain and produces recommendations that better match the true needs of tourists. We illustrate the proposed next POI recommendation approach in a case study and we compare it with a state‐of‐the‐art nearest neighbor‐based next item RS. With the analysis of this case study, we aim at illustrating the specific features of the compared approaches also with the goal to raise the discussion on RSs validation methods, with a particular attention to tourism applications. We finally discuss some significant limitations of current evaluation approaches that must be addressed in future studies.
Iodine Electrochemistry Dictates Voltage‐Induced Halide Segregation Thresholds in Mixed‐Halide Perovskite Devices
Authors: Xu Zhaojian , Kerner Ross A. , Berry Joseph J. , Rand Barry P. 
Published: June 2022

AbstractOwing to straightforward stoichiometry–bandgap tunability, mixed‐halide perovskites are ideal for many optoelectronic devices. However, unwanted halide segregation under operational conditions, including light illumination and voltage bias, restricts practical use. Additionally, the origin of voltage‐induced halide segregation is still unclear. Herein, a systematic voltage threshold study in mixed bromide/iodide perovskite devices is performed and leads to observation of three distinct voltage thresholds corresponding to the doping of the hole transport material (0.7 ± 0.1 V), halide segregation (0.95 ± 0.05 V), and degradation (1.15 ± 0.05 V) for an optically stable mixed‐halide perovskite composition with a low bromide content (10%). These empirical threshold voltages are minimally affected by composition until very Br‐rich compositions, which reveals the dominant role of iodide/triiodide/iodine electrochemistry in voltage‐induced Br/I phase separation and transport layer doping reactions in halide perovskite devices.

AbstractLipid‐based nanoparticles have emerged as a clinically viable platform technology to deliver nucleic acids for a wide range of healthcare applications. Within this scope, one of the most exciting areas of recent progress and future innovation potential lies in the material science of lipid‐based nanoparticles, both to refine existing nanoparticle strategies and to develop new ones. Herein, the latest efforts to develop next‐generation lipid‐based nanoparticles are covered by taking a nanoarchitectonics perspective and the design, nucleic acid encapsulation methods, scalable production, and application prospects are critically analyzed for three classes of lipid‐based nanoparticles: 1) traditional lipid nanoparticles (LNPs); 2) lipoplexes; and 3) bicelles. Particular focus is placed on rationalizing how molecular self‐assembly principles enable advanced functionalities along with comparing and contrasting the different nanoarchitectures. The current development status of each class of lipid‐based nanoparticle is also evaluated and possible future directions in terms of overcoming clinical translation challenges and realizing new application opportunities are suggested.

AbstractFew‐layer black phosphorus (FL‐BP) is a promising high‐mobility semiconductor with thickness‐dependent direct bandgap varying from visible to mid‐infrared region. The poor stability under harsh environment, stemming from irreversible oxidization of P atoms with lone pair electrons, restricts its practical applications. Herein, an electrochemical intercalation and in situ electrochemical deposition (EI&ED) approach to produce scalable Au nanoparticles/FL‐BP crystals with enhanced stability in harsh environment is developed. In this approach, the chemical reactivity of BP is significantly suppressed via the efficient local charge transfer from FL‐BP to electrochemically deposited Au nanoparticles. Thus obtained Au/FL‐BP based nano‐devices show good stability under harsh environment, including i) high humidity of 95%, ii) immersibility in organic agents for as long as 45 days, and iii) annealing at 573 K for 9 h. In addition, compared to bare FL‐BP crystals, Au/FL‐BP based photodetectors present 50‐ and 36‐fold improvement of photoresponsivity at 1550 and 1850 nm via the surface plasmonic enhancement effect. This EI&ED method can produce ultra‐stable FL‐BP crystals at large‐scale, which resolves the crucial barriers in using FL‐BP in large‐scale electronic and optoelectronic devices.

Published: June 2022

AbstractAmong anode materials for potassium‐ion batteries (PIBs), carbon‐based materials attract extensive attention due to their abundant material resources, low cost, high surface capacity, and excellent electrical conductivity. However, carbon‐based materials always display a low initial coulombic efficiency (ICE), which greatly hinders the full utilization of the battery capacity and energy density. Moreover, the slow dynamic process and the large volume expansion during intercalation result in poor cyclic stability. In this work, a sulfonic acid modified porous N‐doped carbon (SA‐NC) is prepared as an anode for PIBs. This SA‐NC material provides abundant migration channels and active potassium storage sites with K+ adsorption energy as low as −1.752 eV, which promote rapidly reversible surface adsorption/desorption capacitance storage of K+, and improve the potassium storage performance and the ICE of the electrode simultaneously. The material exhibits outstanding performance with high reversible initial charging specific capacity (793 mAh g–1 at 0.05 A g–1 current density, 90% capacity retention after 80 cycles), high initial coulomb efficiency (68.21% at 0.1 A g–1), and long‐time hyper‐stable cycling stability (288 mAh g–1 after 2000 cycles at 2 A g–1), which show outstanding performance in all aspects and is at the leading level in carbon anode materials.
