Aims: There is dearth of information on the psychometric of measures of personality on Nigerian population. This study investigates the internal consistencies and validity scores on the Mini- International Personality Item Pool (mini-IPIP) on Nigerian respondents.
Study Design: A cross-sectional survey design was used to validate the scale.
Place of Study: University of Ibadan, Oyo State, South-western Nigeria. Between January and April 2022.
Methodology: A multistage sampling technique was used to select two hundred and nineteen (219) individuals, made up of 113 (51.6%) of males and 106 (48.4%) of females, between the age of 35 and 61 years with Mean age = 46.49 ± SD = 6.23. The participants included administrative, technical and junior staff working in the University of Ibadan, Oyo State, and South-western Nigeria. Participants responded to The Big Five Inventory (BFI-10) and Mini-IPIP. The internal consistencies for the Mini-IPIP was calculated and obtained using Cronbach’s (α) reliability coefficient. Also, the concurrent validity coefficient was obtained using Pearson's Correlation Analysis, Min-IPIP was correlated with BFI-10 in order to ascertain the concurrent validity. The items total correlations were also obtained to test the relationship between each item and the composite/total item score.
Results: A modest but acceptable internal consistency of Extraversion, α =.80; Agreeableness, α =.79, Conscientiousness, α =.84; Neuroticism, α = .83; and Openness to Experience α =.88 for the factors of mini-IPIP was revealed. Positive concurrent validity coefficient was equally observed between the subsections of Mini-IPIP and the BFI-10 (r = .34, .12, .18, .20, .11 for extraversion, agreeableness, conscientiousness, neuroticism, and openness to experience subscales respectively).
Conclusion: These findings provide evidence for the use of Mini-IPIP scale as screening tool for the assessment of human personality in Nigeria based on the five-factor model.

Published: August 2022

AbstractAs an injectable tissue regenerative platform, Anisogel aims to recapitulate the complex and anisotropic architecture of native extracellular matrix by the use of magneto‐responsive microgels, which are oriented under a low magnetic field of ≈100 mT, while a surrounding hydrogel matrix cross‐links around them. This system promotes the oriented growth of neurons when cultured in vitro. In this study, how the local microgel properties affect neurite outgrowth and orientation is aimed to understand using dorsal root ganglia from chicken embryos. When the surrounding matrix is a synthetic poly(ethylene glycol) hydrogel, the microgel concentration and length required to achieve oriented nerve growth is higher compared to fibrin‐based Anisogels. Microgels should be stiffer than the matrix for cells to sense the mechanical anisotropy but a wide range of microgel stiffness leads to similar cell alignment and growth. On the other hand, modification of the microgels with common extracellular matrix molecules enhances nerve growth but deteriorates nerve alignment compared to bioinert microgels in a cell adhesive surrounding gel. Finally, covalently coupling these microgels to the surrounding matrix reduces both cellular orientation and outgrowth suggesting a reduction in the ability of cells to sense the anisotropy.

AbstractUltra‐large graphene oxide (ULGO) is one of the most important graphene derivates because of its processability in constructing various macrostructures with unique properties. However, existing oxidation–exfoliation technologies are limited in the available size range, structure controllability, and preparation efficiency of ULGO by the slow oxidant diffusion among graphite interlayers. Herein, a highly efficient strategy to fabricate ULGO featuring the oxidation of porous graphene networks freshly derived from electrochemical delamination, which highlights the significance of not only creation but also keeping of the fast diffusion channels for oxidant, is proposed. Consuming only 40 min and ultralow oxidant dosage (1 wt equiv.), this economical oxidation realizes high‐yield preparation (≈99.5%) of ULGO with record‐large average size (188.3 µm) and unusual low‐defect structure. Unlike previous reports, free‐standing films assembled from the as‐prepared ULGO exhibit an unexpected electrical conductivity (305.3 S m−1) alongside record‐breaking mechanical properties (21.2 GPa in Young's modulus, 392.1 MPa in tensile strength). Also, the advantage of ULGO in constructing commercially desirable thick graphene films with high thermal conductivity is demonstrated (≈100 µm, 1576.1±26.7 W m−1 K−1). This new strategy based on new findings in mechanism provides a highly efficient route to enlarge lateral size and expand physical properties of graphene oxide.

Published: August 2022

AbstractThe layered transition‐metal‐oxide materials are one type of promising cathode materials for sodium‐ion batteries, which typically include P2, P3, and O3 phases, and each has its own advantages and challenges. Taking into account the complementarity of each single‐phase structure, constructing the composite structures is an efficient pathway to stabilize the structure and improve the electrochemical performance. Herein, three composite cathode materials owning the phase structures of P3/P2, P2/O3, and P3/P2/O3 are prepared by changing the calcinating conditions without introducing any doping element. Among them, the composite of P3/P2/O3 shows the best capacity retention of 80 mAh g–1 after 200 cycles and the highest rate performance of 100 mAh g–1 at a current density of 750 mA g–1. The improved electrochemical performance can be attributed to the staggered arrangement of different phase structures and the gradient Na‐extraction/intercalation voltages of different phases. The slip of the transition metal layer is subjected to the constraint of the adjacent phase structure, thus inhibiting the phase transformation for capacity fading. This work provides an easy way for the preparation of composite cathode structures and brings a clear case for understanding the advantage of composite structures on electrochemical performance.

AbstractCancer stem cells (CSCs) are responsible for the melanoma recurrence, progression, and ineffective therapy. Despite striking anti‐CSCs results in immunotherapy with anti‐programmed death‐1 antibodies (aPD‐1), the therapeutic efficacy is restricted by the evolution of immune evasion of CSCs. Here, a wearable silk‐based microneedle device (SMND) integrating a synergistic immunity and hydrogen therapy is developed. The device mainly consists of a double‐layered MN patch (DLMNP), which employs aPD‐1 loaded silk fibroin (SF) as the inner matrix for immunotherapy, while ammonia borane‐loaded mesoporous silica nanoparticles (AB‐MSN) encapsulated polycaprolactone as the outer thermal‐responsive coating for H2 releasing. SMND can realize thermally responsive drug release triggered by a smartphone for a sustained anti‐CSCs therapy. In B16F10‐CSCs bearing mice melanoma models, the results demonstrates that the synergistic treatment strategy can realize a satisfying antitumor and anti‐CSCs efficacy, which is accompanied by a minimized systemic toxicity. In summary, the smart and synergistic anti‐CSCs features endow SMND as a highly functional platform, which can be potentially extended to chronic disease therapy.

AbstractPerovskite light‐emitting didoes (PeLEDs) have shown considerable potential in solution‐processable display applications. However, the performance of blue PeLEDs in terms of efficiency and stability hinders their practicality on account of severe trap‐mediated nonradiative recombination losses and halide phase segregation. To ameliorate these issues, mixed‐halide sky‐blue perovskite materials are strategically modulated through crystal defect passivation with a trifurcate isocyanate oligomer, which leads to the synergistical suppression of charge trap density and halide ion migration. The proposed approach enables the performance improvement for sky‐blue PeLEDs, exhibiting a peak external quantum efficiency of 14.82% and spectrally stable emission at 487 nm. In addition, prolonged operational lifetime and enhanced capability of moisture resistance are achieved simultaneously, approaching a half‐lifetime of ≈2900 s at an initial brightness of 178 cd m–2.

AbstractThe active structure and catalysis pathway of catalytic materials jointly dominate the thermodynamic energy barrier and kinetic rate during the reactions, which severely restrict their catalysis service behaviors. Herein, the whole dynamic process covering both the structural evolution and the catalysis pathway evolution of model catalyst spinel NiCo2O4 during water oxidation via in situ experiments and theoretical calculations is investigated. Based on the identified authentic terminated active phase NiOOH and figured lattice oxygen oxidation pathway, an effective expedition and optimization of this reconfiguration with a proper doping approach is sufficiently evidenced, to finally establish a life‐time dynamic structure–performance correlation of catalysts and acquire outstanding catalysis activity. Results indicate synergistic deliberation of two critical issues regarding the dynamics of both catalyst structure and catalysis pathway can truthfully benefit the in‐depth understanding of advanced catalysts design and render their performance.

Published: August 2022

AbstractSpinel LiNi0.5Mn1.5O4 (LNMO), high‐voltage and high‐power density, is a very promising cathode candidate. Nevertheless, its lack of cycling stability has historically been long accepted as an inherent issue. Based on the above problem, a strategy is initiated to directly address Mn dissolution and unstable interface structure. A beneficial solid‐phase reaction occurs at the LNMO interface, transforming the spinel phase into two functional phases. One is the layered phase that provides electrochemical activity and supports charge transport. The other is the rock‐salt like phase induced by Li/Mn exchange that can inhibit the dissolution of Mn and provide inert protection. The Li/Mn exchange structure increases the diffusion energy barriers of Mn, which restrains the loss of Mn, proven by the bond valence sum calculation. The two phases are modulated successfully at the LNMO interface to balance the stable material structure and excellent charge transfer, obtaining a sample with excellent electrochemical performance. The capacity retention rate of modified LNMO is 15% higher than that of the pristine sample after 500 cycles. The preparation method does not utilize any dopants or coatings and can play a guiding role in addressing issues regarding structural stability and electrochemical performance for cathode materials.

AbstractExosomes show great potential in diagnostic and therapeutic applications. Inspired by the human innate immune defense, herein, we report engineered exosomes derived from monocytic cells treated with immunomodulating compounds 1α,25‐dihydroxyvitamin D3, and CYP24A1 inhibitor VID400 which are slowly released from electrospun nanofiber matrices. These engineered exosomes contain significantly more cathelicidin/LL‐37 when compared with exosomes derived from either untreated cells or Cathelicidin Human Tagged ORF Clone transfected cells. In addition, such exosomes exhibit multiple biological functions evidenced by killing bacteria, facilitating human umbilical vein endothelial cell tube formation, and enhancing skin cell proliferation and migration. Taken together, the engineered exosomes developed in this study can be used as therapeutics alone or in combination with other biomaterials for effective infection management, wound healing, and tissue regeneration.

Published: August 2022

AbstractWater‐current energy is an enormous and widely distributed clean energy in nature, with different scales from large ocean flow to small local turbulence. However, few effective technologies have been proposed to make use of different forms of water currents as a power source. Here, high‐performance paired triboelectric nanogenerators (P‐TENGs) capable of integrating massively into a thin flexible layer as a structured triboelectric surface (STS) are demonstrated for harvesting water‐current energy. Novel gas packet exchange structure and rigid–flexible coupling deformation mechanism are introduced to ensure that the device can work very effectively even in deep water under high water pressure. The rationally designed TENG array in the STS enables highly efficient power take‐off from the flow. Typically, the STS demonstrates a high‐frequency output up to 57 Hz, largely superior to current TENG devices, and the power density is improved by over 100 times for triboelectric devices harvesting current energy. The flexible STS is capable of attaching to various surfaces or applying independently for self‐powered sensing and underwater power supply, showing great potential for water‐current energy utilization. Moreover, the work also initiates universal strategies to fabricate high‐frequency devices under large environment pressure, which may profoundly enrich the design of TENGs.

Published: August 2022

AbstractStudies of electrosensory systems have led to insights into a number of general issues in biology. However, investigations of these systems have been limited by the inability to precisely control spatial patterns of electrosensory input. In this paper, an electrode array and a system to selectively stimulate spatially restricted regions of an electroreceptor array are presented. The array has 96 channels consisting of chrome/gold electrodes patterned on a flexible parylene‐C substrate and encapsulated with another parylene‐C layer. The conformability of the electrode array allows for optimal current driving and surface interface conditions. Recordings of neural activity at the first central processing stage in weakly electric mormyrid fish support the potential of this system for high spatial resolution stimulation and mapping of electrosensory systems.

Published: August 2022

AbstractThe 2D transition‐metal dichalcogenides (2D TMDCs) are an intriguing platform for studying strong light–matter interactions because they combine the electronic properties of conventional semiconductors with the optical resonances found in organic systems. However, the coupling strengths demonstrated in strong exciton–polariton coupling in the 2D TMDCs remain much lower than those found in organic systems. In this paper, a new approach is taken by utilizing the large oscillator strength of the above‐band gap C exciton in few‐layer molybdenum disulphide (FL‐MoS2). A k‐space Rabi splitting of 293 meV is shown when coupling FL‐MoS2 C excitons to surface plasmon polaritons at room temperature. This value is 11% of the uncoupled exciton energy (2.67 eV or 464 nm), ≈2× what is typically seen in the TMDCs, placing the system in the ultrastrong coupling regime. The results take a step toward finally achieving the efficient quantum coherent processes of ultrastrong coupling in a CMOS‐compatible system—the 2D TMDCs—in the visible spectrum.
