Aim: The main objective of this study is to analyze and compare the pain level and complications of septoplasty with and without splints and packing.
Methodology: Our study comprised of 100 patients who underwent septoplasty procedure both under general and local anesthesia. They were divided into two groups. One group of 50 patient had splints and packing while the other group of 50 patients had no splints and packing post operatively. Patients were chosen randomly. Children and elderly patients were excluded from the study. Printed proforma was used to compare the result in terms of pain scores and complications. Regular follow-up was done for average six months. The study was approved by ethical review board PUMHSW Nawabshah.
Results: Pain scores were higher in patients with splints and packing both in post-operative period and at the time of removal of splints and packing. There was no significant difference regarding other post operative complications.
Conclusion: It is concluded that pain and discomfort associated with nasal splints and packing does not justify their application in case of certain minor to moderate nasal septal defects undergoing surgery. However when septal surgery is extensive and associated turbinate and framework procedure are done, splints and packing become mandatory in our setup.

Published: July 2022

AbstractHigh‐entropy oxides (HEO) with high stability and designability are potential microwave absorbers that serve in harsh environments. However, loss design is critical for the absorption performance of HEO due to its weak intrinsic loss capability. Inadequate loss ability results in considerable secondary reflection. Here, an in situ conductive heterogeneous phase is constructed in (Fe0.2xCo0.2Ni0.2Cr0.2Mn0.2)3O4 (x = 1–5) using a reductive circumstance, to form a dual‐phase composite. Both the ohmic and dielectric loss are enhanced as the conductive phase is introduced, while great impedance matching condition is well maintained. Hence, the composites can achieve substantial absorption across the whole X or Ku band with a thin thickness. Furthermore, key efforts are made to reveal the relationship between the absorbing performance and loss capability of an absorber. The analytical expression of the theoretical threshold of attenuation constant is derived. Based on the statistics of experimental data, the broad feasibility and practicability of the proposed theoretical threshold of attenuation constant are confirmed and discussed. Combined with both the theoretical and experimental studies, the mechanism by which the conductive phase contributes to increased absorption is also disclosed, providing an effective basis for the loss design of broadband microwave absorbers.

AbstractInterfacial coupling strategy has allured extensive attention for the possibility to endow active electrode materials with superior performance. However, the design of strong coupling engineering with interfacial evolution during electrochemical processes is very challenging. Herein, inspired by the powerful robotic arms and density functional theory calculations, multiple functional groups identified with intense affinity to V atom are successfully grafted on carbon nanotubes (CNTs), thereby in situ building robust interfacial bonds (VOC and VC) to tightly anchor VS4 particles. The largely decreased band gaps and energy barriers show the fortified conductivity of VS4‐CNT heterostructure. Besides, the spacial confinement effect induced by interfacial linkages substantively enhances the mechanical properties to inhibit structural collapse, and restrains the dissolution of polysulfides as verified by molecular dynamics simulations, thus prolonging life span. Excellent energy density of 105.5 Wh kg–1 can be delivered after assembling full sodium‐ion capacitors (activated carbon//VS4‐CNT). Significantly, the reversible interfacial bonds confirmed by various ex situ characteristics during discharge/charge processes hold the key to remarkable sodium storage ability and prominent initial coulombic efficiency. More impressively, strong interfacial coupling effect can establish synergistic soft‐rigid integrated solid‐electrolyte interphase film, which is conducive to elevating the electrochemical performance of electrodes, convincingly constructing advanced sodium‐ion capacitors.

AbstractDesign of efficient and robust electrocatalysts for hydrogen evolution reaction (HER) under all pH conditions has attracted significant attention. In particular, it is still a considerable challenge since the HER kinetics of Pt in alkaline solutions is about two to three orders of magnitude lower than that in acidic conditions. Herein, a heterogeneous yolk–shell nanostructure with Rh nanoparticles embedded in S, N co‐doped carbon nanospheres prepared by a facile self‐template method is reported. The optimized electrocatalyst can achieve an extremely small overpotential of 13.5 mV at 10 mA cm‐2, low Tafel slope of 25.5 mV dec‐1, high turnover frequency of 0.143 s‐1 (at −75 mV vs. reversible hydrogen electrode), and long‐term durability for 10 h, which is the record‐high alkaline HER activity among the ever‐reported noble metal based catalysts. These striking performances are ascribed to the optimized electronic structure and unique heterogeneous yolk–shell nanostructure. More importantly, it is also demonstrated that the obtained electrocatalyst exhibits superior activities in all pH range, which is better than commercial Pt/C and Rh/C catalysts. This work proves that Rh‐based nanomaterials are promising superior electrocatalysts in a wide pH range and nanostructure design is a powerful tool to increase the mass/electron transfer during reaction.

AbstractAlthough hydrogels are still in their infancy, research is primarily focused on optimizing their mechanical, antibacterial, anti‐frost, and water‐retaining properties. However, the rapid preparation of hydrogels without external energy stimulation remains a significant challenge. In this study, a Fe3O4‐COOH@MXene@silk fibroin@polyacrylamide hybrid hydrogel (FM@SF‐PAAM) is successfully fabricated using an innovative rapid gelation method, which can initiate the gelation process as low as 7 s and formed at an extremely rapid rate at room temperature, without the use of external energy. The as‐obtained FM@SF‐PAAM hybrid hydrogel exhibits excellent electrical conductivity (6.44 × 10–2 S m–1) and mechanical properties, with a maximum strain of 1660%. Additionally, the FM@SF‐PAAM‐based flexible strain sensor can monitor joint movement and emotional changes, such as finger and elbow bending, glaring, smiling, and mouth opening. Thus, the radical polymerization process demonstrates the immense potential for application to nearly all types of MXene‐based hydrogels and is likely to serve as a foundation for the development of flexible hydrogel‐based devices.

AbstractColloidal quantum dot‐based light‐emitting diodes (QD‐LEDs) are one of the potential future self‐emissive displays owing to their large‐scale solution‐processibility and high color purity. For the industrial application of QD‐LEDs, high‐performance QD‐LED and high‐resolution patterning of quantum dot (QD) films are required. Photolithography is an ideal tool for patterning QD films. Previously, the high‐resolution patterning of QD films using direct photolithography by ultra‐thin atomic layer deposition of ZnO on the QD surface is reported. The patterning process is acceptable for Cd‐based QD films, but the photoresist severely deteriorates the photoluminescence (PL) intensity of InP‐based QD films owing to the presence of sulfonic groups in the photoactive compound. Herein, a non‐destructive direct photolithography process for QD film patterning using a negative photoresist that does not affect the PL intensities of Cd‐ and InP‐based QD films is reported. The effect of the photoresist is also verified by a PL lifetime study. Extremely bright Cd‐ and InP‐based QD films are successfully patterned using a softer photoresist, and micropatterning of InP‐based QD films is reported for the first time in this work using photolithography. A QD electroluminescence device is also successfully fabricated using the patterning method.

AbstractLocalized surface plasmon resonances (LSPRs) in metallic nanostructures attract great attention for their potential applications such as highly sensitive optical sensors. However, the performance of LSPR sensors is strongly hampered by their low quality (Q) factors due to the intrinsic ohmic losses and far‐field radiation losses. Here, a kind of all‐metal metasurfaces that can achieve high‐Q and high figure of merit (FOM) resonances based on bound states in the continuum (BICs), is theoretically designed and experimentally demonstrated. The devices can simultaneously exhibit symmetry‐protected and Friedrich–Wintgen quasi‐BICs features at normal incidence, leading to higher Q‐factors than those solely inspired by single quasi‐BIC. Additionally, the constraint of symmetrical dielectric environment for common metasurfaces can be released by utilizing a metal substrate rather than a dielectric one. The proof‐of‐concept experiments demonstrate the high performances of such dual quasi‐BIC based plasmonic refractive index sensors with the Q‐factor of 145, the sensitivity of 657 nm RIU‐1, and the FOM of 109 RIU‐1. These findings may stimulate some promising applications, such as biosensing, optical lasing, and light absorption.

Abstract2D transition metal dichalcogenides have shown great potential for next‐generation microelectronic devices owing to their ability to prolong the life of Moore's law by mitigating the short‐channel effect. Recently, many efforts have been made on doping 2D films to create p‐n junctions, in which plasma implantation has been placed great expectations due to its CMOS process compatibility. However, ultrathin vertical 2D p‐n homostructure with excellent rectification behaviors have rarely been studied so far. Herein, MoS2 van der Waals p‐n homojunctions are fabricated by highly efficient N2 plasma implantation. Kelvin probe force microscope reveals the surface potential difference of ≈130 mV between n‐MoS2 and p‐MoS2. The fabricated field‐effect transistor (FET) presents a high rectification ratio up to 3.1 × 10–3 at the gate bias VGS = 20 V, which is over 20 times larger than that of the vertical homojunction obtained by surface chemical doping. The forward current is mainly dominated by both the interlayer recombination and band‐to‐band tunneling, while the ultra‐low reverse current in the order of 10 pA is governed by direct tunneling. The results demonstrate a new CMOS‐compatible way to fabricate vertical 2D homojunction, which is the basic structure of many low‐dimensional microelectronic devices.

AbstractPolythiophenes (PTs) have attracted considerable interest for application in organic solar cells (OSCs) owing to their simple molecular structures and low‐cost synthesis. However, the power conversion efficiencies (PCEs) of PT‐based OSCs are lower than those of state‐of‐the‐art OSCs. Herein, the development of two sequentially fluorinated PT donors (PT‐2F and PT‐4F) is reported for realizing highly efficient OSCs. PT‐2F and PT‐4F are designed to contain two and four fluorine atoms, respectively, per repeating unit to decrease their highest occupied molecular orbital energy levels and increase the open‐circuit voltages of the OSCs. Importantly, the PT‐4F polymers exhibit high backbone rigidity and the desired temperature‐dependent aggregation behavior, affording well‐developed crystalline structures in thin films for efficient charge transport. These beneficial features promote the construction of an optimal blend morphology of PT‐4F:small‐molecule acceptor with a suitable energy offset and low energetic disorder. Thus, the PT‐4F‐based binary and ternary OSCs achieve high PCEs of 15.6% and 16.4%, respectively.

AbstractThe broad implementation of thermoelectricity requires high‐performance and low‐cost materials. One possibility is employing surfactant‐free solution synthesis to produce nanopowders. We propose the strategy of functionalizing “naked” particles’ surface by inorganic molecules to control the nanostructure and, consequently, thermoelectric performance. In particular, we use bismuth thiolates to functionalize surfactant‐free SnTe particles’ surfaces. Upon thermal processing, bismuth thiolates decomposition renders SnTe‐Bi2S3 nanocomposites with synergistic functions: 1) carrier concentration optimization by Bi doping; 2) Seebeck coefficient enhancement and bipolar effect suppression by energy filtering; and 3) lattice thermal conductivity reduction by small grain domains, grain boundaries and nanostructuration. Overall, the SnTe‐Bi2S3 nanocomposites exhibit peak z T up to 1.3 at 873 K and an average z T of ≈0.6 at 300–873 K, which is among the highest reported for solution‐processed SnTe.

Feste Gashydrate II. Struktur und Raumchemie
Authors: v. Stackelberg M. , Müller H. R. 
Published: July 2022

AbstractDurch röntgenographische Untersuchungen sind bei den Gashydraten zwei kubische Strukturen festgestellt worden:Struktur I. a ≃ 12 Å mit 46 Wassermolekeln in der Elementarzelle, die ein Gerüst mit 2 Hohlräumen der Koordinationszahl 20 und 6 Hohlräumen der Koordinationszahl 24 bilden. Die Idealzusammensetzung bei Besetzung aller Hohlräume mit Gasmolekeln M ist daher M · 53/4 H2O.Struktur II. a ≃ 17,3 Å mit 136 Wassermolekeln, die ein Gerüst mit 16 Hohlräumen mit der Koordinationszahl 20 und 8 großen Hohlräumen mit der Koordinationszahl 28 bilden. Diese Hydratstruktur wird von Stoffen (meist Flüssigkeiten) mit größeren Molekeln (6 bis 7 Å Durchmesser) gebildet, wobei nur die großenHohlräume besetzt werden. Die Idealzusammensetzung ist also M · 17H2O.Die kleinen Hohlräume der Struktur II können zusätzlich durch kleine Molekeln besetzt werden, und zwar entweder unter Bildung einer Mischphase (z.B. CCl4‐N2‐Hydrat) mit druckabhängigem Gehalt an kleinen Molekeln oder unter Bildung einer Verbindung mit nur temperaturabhängigem Dissoziationsdruck. Letzteres ist der Fall, wenn die kleinen Hohlräume mit H2S oder H2Se besetzt werden. Dies sind die de Forcrandschen„ Doppelhydrate”︁, deren Idealzusammensetzung demnach M · 2H2S · 17H2O ist.Die Bedingungen für die Bildung von Hydraten der hier behandelten Art werden festgelegt. Neben den Bedingungen einer homöopolaren nicht salzartigen Natur der Hydratbildner, der Nichtmischbarkeit mit Wasser (Unfähigkeit zur Wasserstoffbrückenbindung) und einer genügenden Kleinheit der v. d. Waalsschen Kräfte (K. P. unter 60° C) ist die richtige Größe der Molekeln entscheidend. Es ist anzunehmen, daß die Molekeln in den Hohlräumen rotieren.

AbstractFluorescence (FL) quenching of 3‐aminoquinoline (3AQ) by halide ions
has been explored in an aqueous acidic medium using the steady‐state and time‐domain FL measurement techniques. The halide ions showed no significant change in the absorption spectra of 3AQ in an aqueous acidic medium. The FL intensity was strongly quenched by
ions and the order of FL quenching by halide ions was
. The decrease in FL lifetime along with the reduction in FL intensity of 3AQ suggested the dynamic nature of quenching. The obtained
values were 328

ions and 119

hMSCs in contact with DMSO for cryopreservation: Experiments and modeling of osmotic injury and cytotoxic effect

Published: July 2022

AbstractIn this study a combined analysis of osmotic injury and cytotoxic effect useful for the optimization of the cryopreservation process of a cell suspension is carried out. The case of human Mesenchymal Stem Cells (hMSCs) from Umbilical Cord Blood (UCB) in contact with dimethyl sulfoxide (DMSO) acting as Cryo‐Protectant Agent (CPA) is investigated from the experimental as well as the theoretical perspective. The experimental runs are conducted by suspending the cells in hypertonic solutions of DMSO at varying osmolality, system temperature, and contact times; then, at room temperature, cells are pelleted by centrifugation and suspended back to isotonic conditions. Eventually, cell count and viability are measured by means of a Coulter counter and flow‐cytometer, respectively. Overall, a decrease in cell count and viability results when DMSO concentration, temperature, and contact time increase. A novel mathematical model is developed and proposed to interpret measured data by dividing the cell population between viable and nonviable cells. The decrease of cell count is ascribed exclusively to the osmotic injury caused by expansion lysis: excessive swelling causes the burst of both viable as well as nonviable cells. On the other hand, the reduction of cell viability is ascribed only to cytotoxicity which gradually transforms viable cells into nonviable ones. A chemical reaction engineering approach is adopted to describe the dynamics of both phenomena: by following the kinetics of two chemical reactions during cell osmosis inside a closed system it is shown that the simultaneous reduction of cell count and viability may be successfully interpreted. The use of the Surface Area Regulation (SAR) model recently proposed by the authors allows one to avoid the setting in advance of fixed cell Osmotic Tolerance Limits (OTLs), as traditionally done in cryopreservation literature to circumvent the mathematical simulation of osmotic injury. Comparisons between experimental data and theoretical simulations are provided: first, a nonlinear regression analysis is performed to evaluate unknown model parameters through a best‐fitting procedure carried out in a sequential fashion; then, the proposed model is validated by full predictions of system behavior measured at operating conditions different from those used during the best‐fit procedure.
