Comparative Efficacy of Knotless (Polyglyconate) Over Conventional (Poliglecaprone 25) Suture as a Wound Closure Material in Mandibular Impacted third Molar Surgery (MI3M)
Authors: Agrawal Pooja , Jadhav Anendd 
Published: February 2022

Background: The third molar surgery is the most commonly practised minor oral surgery in dental clinic. Post-operatively the patient suffers from pain, swelling and trismus due to tissue injury during surgical procedure. After extraction of third molar, conventional sutures are used for primary closure of the wound. During the procedure the clinician get difficulties intra-orally related to knot placement, limitation of instrument accessibility and knot slippage. Barbed sutures are the knotless suture which help in adhering the tissue while suturing.
Objectives: The primary focus of the study is to evaluate the efficacy of knotless suture as a wound closure agent in terms of post-operative pain, swelling, trismus, degree of wound healing and quality of life over the conventional one.
Methodology: Two groups (study & control) with 20 individuals as subjects are considered for the study model. Systemically healthy individual with presence of at least one mesioangular or horizontal or vertically oriented mandibular impacted third molar(MI3M) with similar difficulty index, depth of, and relationship with ramus will be included in the study sample. Wound closure would be achieved by using 3-0 knotless suture using continuous sub-cuticular suturing technique for the study group and 3-0 conventional suture using simple interrupted suturing technique for control group respectively. Post-operatively measurement of pain, swelling, trismus, degree of wound healing and quality of life will be done.
Expected Results: Knotless suture for closure of wound after MI3M surgery will be effective in reducing post-operative pain, edema and trismus and also helpful in better wound healing and improve quality of life.
Conclusion: Use of knotless barbed suture after surgical removal of lower impacted third molar to simplify intra-oral suturing technique and to reduce post-operative pain, swelling, trimus and knot related complications would be a familiar and effective way which could be executed by a dental practitioner himself.

Authors: Zuo Genmei , Lin Lijia 
Published: February 2022

AbstractThe purpose of the experiment was to investigate whether using the summarizing strategy can further engage learners in a computer‐based environment where different forms of finger tracing were incorporated. One hundred and fifty‐six university students were randomly assigned to one of six conditions formed by a 3 (hand tracing vs. observing tracing vs. no tracing) × 2 (summarizing vs. no summarizing) factorial design. Results revealed that using the summarizing strategy led to better retention than not using the strategy, but the effect disappeared on transfer. Moreover, individuals in the observing tracing condition had significantly higher ratings on perceived interest and germane cognitive load than their peers in other conditions. These findings, as well as the limitations and future directions, were discussed within the engagement framework, social agency theory, and cognitive load theory.
The effect of hint strength on the benefits of retrieval practice
Authors: Vaughn Kalif E. , Fitzgerald Grant , Hood Dasia , Migneault Karlee , Krummen Kelly 
Published: February 2022

AbstractRecent work has shown that retrieval hints can make test trials more enjoyable without sacrificing learning. We investigated the extent to which this effect was moderated by hint strength. Both experiments utilized a within‐participants design. In Experiment 1 (n = 41), participants studied skeletal charts highlighting a bone region. After study, participants received one test trial with either consonants‐only (e.g., _cc_p_t_l), vowels‐only (e.g., o__i_i_a_), or no hint (e.g., _________). Retrieval latencies were fastest for the consonants‐only items, suggesting they provided the strongest hints. Although the consonants‐only trial produced the worst final test performance, participants rated that trial as the most effective, the most fun, and the trial they would use from now on. Experiment 2 (n = 32) replicated and extended these results using a criterion learning paradigm. These experiments show that participants prefer extremely strong hints during test trials, even when such hints impair performance.

Published: February 2022

AbstractReactive oxygen species (ROS) production efficiencies of the nanocatalysts are highly desired for cancer therapy, but currently the ROS generation efficiency is still far from defecting the tumors. Therefore, improving their ROS generation ability is highly desirable for cancer therapy. Herein, inspired by the electrostatic preorganization effect during the catalysis of natural protein enzymes, a human self‐driven catalysis‐promoting system, TENG‐CatSystem is developed, to improve catalytic cancer therapy. The TENG‐CatSystem is mainly composed of three elements: a human self‐driven triboelectric nanogenerator (TENG) as the electric field stimulator to provide electric pulses with high biosafety, a nanozyme comprising a 1D ferriporphyrin covalent organic framework coated on a carbon nanotube (COF‐CNT) to generate ROS, and a COF‐CNT‐embedded conductive hydrogel that can be injected into the tumor tissues to increase local accumulation of COF‐CNT and decrease the electrical impedances of tissues. Under the human self‐generated electric field provided by the wearable TENG, the peroxidase‐like activity of the COF‐CNT is fourfold higher than that without an electric field. Highly malignant 4T1 breast carcinoma in mice is significantly suppressed using the TENG‐CatSystem. The human self‐driven TENG‐CatSystem not only demonstrates high catalytic ROS generation efficiency for improved cancer therapy, but also offers a new therapeutic mode for self‐driven at‐home therapy.

Published: February 2022

AbstractCircularly polarized room‐temperature phosphorescence (CPRTP) is of paramount importance for applications in information encoding, bioimaging, and optoelectronic devices, however, it remains challenging to organize highly efficient CPRTP materials with controlled handedness and long afterglow. Herein, as an outstanding novel finding, it is diclosed that ultralong CPRTP with on‐demand chiroptical properties is simple to realize using the earth‐abundant cellulose and silica. It is shown that left‐handed chiral nematic nanoporous silica films featuring defect photoluminescence enable ultralong CPRTP with an unprecedented control of the handedness. This work presents that the chiral nematic nanoporous silica films display right‐handed CPRTP and left‐handed CPRTP with the phosphorescence dissymmetry factors up to −0.130 and 0.093 as well as the afterglow lifetimes of 1.094 and 0.949 s, respectively. The potential of the transparent chiral nematic nanoporous silica films, capable of ultralong CPRTP and selective reflection of left‐handed circularly polarized light, for the development of anticounterfeiting optical labels is showcased. This work presents a versatile strategy and a step toward the development of ultralong CPRTP materials with on‐demand chiroptical properties from readily available defect phosphors for photonic applications.

Published: February 2022

AbstractUnderstanding photogenerated charge transport is critical to further improving the performance of perovskite‐based devices. In this study, the low‐defect perovskite CH3NH3PbX3 (X = Br or Cl) single crystals, which are an ideal platform for high‐quality optoelectronic devices, are fabricated to examine characteristics of photodetectors with electrodes with Au or Ag, and interlayer of TiO2. The transport mechanism of the photogenerated carriers in each device is elucidated by analysis of the current density–voltage curves under dark or a 405 nm of super‐bandgap illumination or a 640 nm of sub‐bandgap illumination. The photocurrent under the 405 nm illumination is improved under the hole‐dominant Au‐device of p‐type bromide crystals and the electron‐dominant Ag‐device of n‐type chloride crystals. The defect‐assisted excitation under 640 nm illumination is associated with generation of the holes with the defects located near the conduction band or the electrons with the valence band in each perovskite materials. With this conception, the responsivity of 0.07 A W−1, specific detectivity over 1011 Jones, and external quantum efficiency around 16% are obtained in the best performing devices. The present results suggest a promising strategy for designing efficient photodetectors using photogenerated and trap‐assisted photocarriers that contribute to enhanced photocurrent.

AbstractSelf‐powered smart windows are highly attractive for the development of energy‐efficient buildings system, owing to their superior capacities in regulating the energy and information exchange between indoor and outdoor environments. Although immense achievement has been made in the self‐powered cholesteric liquid crystal smart window (CLC‐SW) based on triboelectric nanogenerators (TENGs), such a self‐powered manner is limited by some challenges such as the need of the continuous input of external forces, as well as unstable performance owing to inevitable mechanical abrasion of TENGs surface. Here, a fully self‐powered CLC‐SW is developed by leveraging droplet‐based electricity generator (DEG) as a spontaneous and sustained energy reservoir, in which DEG has superior capacities to harvest ceaseless energy from ambient environment and circumvent any additional electrical power input. It is demonstrated that DEG‐driven CLC‐SW exhibits a rapid response and high tunability in the transformation between the transparent state and the hazy state in a wide range of solar spectrum. Moreover, both the transparent and hazy modes can be self‐sustained for a long time, also be reversibly switched by the gentle mechanical pressure loading. The DEG‐driven smart window developed in this work can find applications such as indoor temperature modulation and privacy information protection.

Published: February 2022

AbstractMany fascinating device applications of chiral nematic materials are determined by their helical axis orientations. Cellulose nanocrystals (CNCs) self‐assemble producing left‐handed chiral nematic films with predominant planar textures. While varied techniques have been exploited to tune the helical axis orientations, it remains challenging to produce concentrically aligned chiral nematic state. Herein, the authors report novel findings that left‐handed chiral nematic CNC films formed with homeotropic concentric helix orientations in the planar textures can be realized by local radial magnetic field‐directed self‐assembly of CNCs. These chiral nematic CNC films display left‐handed circular polarization patterns and transform spontaneous luminescence to right‐handed circularly polarized luminescence on both film plane and lateral surfaces owing to the underlying photonic bandgaps. These plane‐lateral chiroptical properties can be tuned simultaneously from the visible to the near‐infrared spectral regime. Their work presents a step towards the development of self‐organized chiroptical materials encoded with complex polarization features for photonic applications.

Published: February 2022

AbstractIn this work, the potential application of cubine monolayer as a highly sensitive sensor for the detection and capture of toxic gas molecule NO2 is investigated by employing density functional theory (DFT) calculations. Eight gas molecules, namely CO, CO2, CH4, H2S, SO2, NH3, NO, and NO2 are considered. After examining the adsorption energy, adsorption distance, variation of bond length and Mulliken charge, the results show that only NO2 molecule present chemical adsorption on cubine monolayer. The calculated work functions and I–V curves indicate that cubine has the highest sensitivity to NO2 molecules. The adsorption energies decrease following the increase of strain in both A and B directions, when the strain along the A direction reaches 12%, the adsorption energy decreases to −0.686 eV, which shows physical adsorption. This provides a desorption strategy for recycling. The calculations employed in this work indicate that the cubine monolayer can be a prominent candidate for the application of a super sensor to detect and capture NO2 toxic gas molecules.

Published: February 2022

AbstractThe parameter optimization coupled with the control strategy and target driving cycle directly affects the performance of vehicles. This paper proposes an optimization approach for a plug‐in hybrid electric truck (PHET), which considers comprehensive performances including fuel economy, emissions, vehicle drivability, safety, and dynamics. First, 10 initial design parameters are selected from powertrain components and a real‐time energy management strategy (EMS). Then, a definitive screening design (DSD) is proposed to simplify the design parameters. Finally, non‐dominated sorting genetic algorithm‐III (NSGA‐III) is proposed to solve a constrained many‐objective optimization problem with 9 objectives, and the design space is refined through a sensitivity analysis. Simulation results demonstrate that the proposed optimization approach can achieve significant improvements regarding both the comprehensive performances, power repartition, and system efficiency. The simulation is conducted both on Chinese Heavy‐Duty Commercial Vehicle Test Cycle (CHTC) and Urban Dynamometer Driving Schedule for Heavy‐Duty Vehicles (UDDSHDV). In addition, to guide a decision maker (DM) to make trade‐offs among many objectives, preferences are also incorporated into the solutions.

AbstractIn magnetic systems, spin and exchange disorder can provide access to quantum criticality, frustration, and spin dynamics, but broad tunability of these responses and a deeper understanding of strong limit disorder are lacking. Here, it is demonstrated that high entropy oxides present a previously unexplored route to designing materials in which the presence of strong local compositional disorder may be exploited to generate tunable magnetic behaviors—from macroscopically ordered states to frustration‐driven dynamic spin interactions. Single‐crystal La(Cr0.2Mn0.2Fe0.2Co0.2Ni0.2)O3 films are used as a model system hosting a magnetic sublattice with a high degree of microstate disorder in the form of site‐to‐site spin and exchange type inhomogeneity. A classical Heisenberg model simplified to represent the highest probability microstates well describes how compositionally disordered systems can paradoxically host magnetic uniformity and demonstrates a path toward continuous control over ordering types and critical temperatures. Model‐predicted materials are synthesized and found to possess an incipient quantum critical point when magnetic ordering types are designed to be in direct competition, this leads to highly controllable exchange bias behaviors previously accessible only in intentionally designed bilayer heterojunctions.
