Published: January 2022

The demand for Li secondary batteries is increasing, with the need for batteries with a higher level of performance and improved safety features. The use of a highly concentrated aqueous electrolyte solution is an effective way to increase the safety of batteries because it is possible to use “water-in-salt” (WIS) and “hydrate-melt” (HM) electrolytes for practical applications. These electrolytes exhibit a potential window of &gt;3.0 V, which is attributed to the difference between the HOMO and the LUMO energies of the n orbital of the pure water molecules and that of the water molecules in the hydration shells of a metal ion, according to theoretical predictions. Thus, in the present study, the attenuated total reflectance (ATR)-far-ultraviolet (FUV) spectra of water and super-concentrated aqueous solutions, such as WIS and HM using a Li salt, were experimentally investigated. The effects of anions, cations, and deuteriums on the ATR-FUV spectra were examined. The ATR-FUV method is an excellent means of studying highly concentrated aqueous salt solutions. The results suggest that the transition energy of water molecules in an ultrahighly concentrated aqueous electrolyte containing HM and WIS increased by nearly 0.4 eV (corresponding to an energy shift of over 10 nm) compared to an aqueous electrolyte with a typical water concentration. It was also revealed that the transition energy of water changes depending on the environment of the non-bonding electron, which is directly connected with or affected by hydrogen bonding with other water molecules or directly connected with Li+.

Published: January 2022

Significance
RAF inhibitors unexpectedly induce ERK activation in normal and oncogenic RAS tumor cells, making them unsuitable for treating RAS-driven cancers. The precise mechanism of this paradox is not fully understood but is believed to be RAS dependent. In this study, we discovered that classical RAS proteins are not essential for RAF inhibitor-induced ERK activation in H/N/KRAS-less mouse embryonic fibroblasts. We further showed that the MRAS/SHOC2 complex is required for the classical RAS-independent paradoxical ERK activation. Our findings provide new insights into the mechanism of paradoxical ERK activation by RAF inhibitors, and they have important therapeutic implications for developing effective RAF inhibitors.
The 4D Einstein–Gauss–Bonnet theory of gravity: a review
Authors: Fernandes Pedro G S , Carrilho Pedro , Clifton Timothy , Mulryne David J 
Published: January 2022

Abstract
We review the topic of 4D Einstein–Gauss–Bonnet (4DEGB) gravity, which has been the subject of considerable interest over the past two years. Our review begins with a general introduction to Lovelock’s theorem, and the subject of Gauss–Bonnet terms in the action for gravity. These areas are of fundamental importance for understanding modified theories of gravity, and inform our subsequent discussion of recent attempts to include the effects of a Gauss–Bonnet term in four space–time dimensions by re-scaling the appropriate coupling parameter. We discuss the mathematical complexities involved in implementing this idea, and review recent attempts at constructing well-defined, self-consistent theories that enact it. We then move on to consider the gravitational physics that results from these theories, in the context of black holes, cosmology, and weak-field gravity. We show that 4DEGB gravity exhibits a number of interesting phenomena in each of these areas.

Published: January 2022

Abstract
In this paper, shielding gas (He) and shielding quartz tube (straight tube and conical tube) is added to nanosecond pulsed He gas–liquid discharge (G-LD) to limit the air diffusion into plasma, and for the purposes of enhancing the plasma volume and productions of ċOH and H2O2. The plasma properties, including current–voltage waveforms, the temporal-resolved discharge images, optical emission spectra, gas temperature, electron density, and the ċOH and H2O2 productions are analyzed and compared among different discharges generated under the cases of no shielding, shielding He gas, shielding straight tube, and shielding conical tube. The results show that adding extra shielding gas and tubes in the discharge reactor can decrease the gas temperature and electron density, but enhance the plasma volume and area of plasma-liquid interface in comparison with no shielding case. Besides, the addition of shielding gas has the most benefit for enhancing the productions of ċOH and H2O2 produced by G-LD. Adding a shielding conical tube slows down the decrease extent of ċOH and H2O2 productions caused by increasing discharge gap. When the discharge gap excesses 6 mm, adding a shielding conical quartz also has an obvious increase effect on the production of ċOH and H2O2 in compared with no shielding case. While adding a shielding straight tube with small diameter has a little effect on H2O2 production, even a negative effect on ċOH production.
Optical non-reciprocity with multiple modes in the visible range based on a hybrid metallic nanowaveguide
Authors: Cheng Yuqing , Zhai Kunpeng , Zhu Ninghua , Sun Mengtao 
Published: January 2022

Abstract
Optical non-reciprocity is a significant property in numerous applications, ranging from optical telecommunications and optical signal processing to integrated photonics and quantum networks. Here, we theoretically demonstrate passive optical non-reciprocity with multiple modes in the visible range, employing a simple hybrid plasmonic nanostructure, which consists of a metallic cavity waveguide with two groups of gratings on both sides (ports). This structure illustrates high isolation ratios for these modes with values of around 10–30 dB. The maximum isolation ratio is close to 30 dB at the wavelength of 548 nm with the bandwidth of 16 nm. Furthermore, the intensity of the electric field localized inside the waveguide is highly enhanced by about 1 order of magnitude for these resonant modes. Our work presents a novel way for realizing optical non-reciprocity with multiple modes in the visible range, which is helpful forassociated applications.
The generalized continuous multiple step (GCMS) potential: model systems and benchmarks
Authors: Munguía-Valadez Jorge , Chávez-Rojo Marco Antonio , Sambriski Edward John , Moreno-Razo José Antonio 
Published: January 2022

Abstract
The generalized continuous multiple step (GCMS) potential is presented in this work. Its flexible form allows for repulsive and/or attractive contributions to be encoded through adjustable energy and length scales. The GCMS interaction provides a continuous representation of square-well, square-shoulder potentials and their variants for implementation in computer simulations. A continuous and differentiable energy representation is required to derive forces in conventional simulation algorithms. Molecular dynamics simulations are of particular interest when considering the dynamic properties of a system. The GCMS potential can mimic other interactions with a judicious choice of parameters due to the versatile sigmoid form. In this study, our benchmarks for the GCMS representation include triangular, Yukawa, Franzese, and Lennard-Jones potentials. Comparisons made with published data on volumetric phase diagrams, liquid structure, and diffusivity from model systems are in excellent agreement.
Inhomogeneous linear responses and transport in armchair graphene nanoribbons in the presence of elastic scattering
Authors: Bahrami Mousa , Vasilopoulos Panagiotis 
Published: January 2022

Abstract
Within linear-response theory we derive a response function that thoroughly accounts for the influence of elastic scattering and is valid beyond the long-wavelength limit. We use the theory to evaluate the polarization function and the conductivity in metallic armchair graphene nanoribbons in the Lindhard approximation for intra-band and inter-band transitions and for a relaxation time τ that is not constant. We obtain a logarithmic behaviour in the scattering-independent polarization function not only for intra-band transitions, as is usually the case for one-dimensional systems, but also for inter-band transitions. Modifying the screening wave vector and the impurity density in the long-wavelength limit strongly influences the relaxation time. In contrast, for large wave vectors, this modification leads to a conservative value of τ . We show that the imaginary part of the impurity-dependent conductivity varies with the wave vector while its scattering-independent part exists only for a single value of the wave vector.

Published: January 2022

Abstract
In recent years, nanozymes based on two-dimensional (2D) nanomaterials have been receiving great interest for cancer photothermal therapy. 2D materials decorated with nanoparticles (NPs) on their surface are advantageous over conventional NPs and 2D material based systems because of their ability to synergistically improve the unique properties of both NPs and 2D materials. In this work, we report a nanozyme based on flower-like MoS2 nanoflakes (NFs) by decorating their flower petals with NCeO2 using polyethylenimine (PEI) as a linker molecule. A detailed investigation on toxicity, biocompatibility and degradation behavior of fabricated nanozymes in wild-type Drosophila melanogaster model revealed that there were no significant effects on the larval size, morphology, larval length, breadth and no time delay in changing larvae to the third instar stage at 7–10 d for MoS2 NFs before and after NCeO2 decoration. The muscle contraction and locomotion behavior of third instar larvae exhibited high distance coverage for NCeO2 decorated MoS2 NFs when compared to bare MoS2 NFs and control groups. Notably, the MoS2 and NCeO2-PEI-MoS2 NFs treated groups at 100 μg ml−1 covered a distance of 38.2 mm (19.4% increase when compared with control) and 49.88 mm (no change when compared with control), respectively. High-resolution transmission electron microscopy investigations on the new born fly gut showed that the NCeO2 decoration improved the degradation rate of MoS2 NFs. Hence, nanozymes reported here have huge potential in various fields ranging from biosensing, cancer therapy and theranostics to tissue engineering and the treatment of Alzheimer’s disease and retinal therapy.
Temperature-dependent dielectric properties of CsPb2Br5: a 2D inorganic halide perovskite
Authors: Sahoo Aditi , Paul Tufan , Maiti Soumen , Banerjee Rupak 
Published: January 2022

Abstract
Two dimensional (2D) CsPb2Br5 have been successfully synthesized via the chemical precipitation method. Detailed structural, morphological, optical, and dielectric studies of these materials have been performed. These 2D CsPb2Br5 plates (of thickness around 200–300 nm) are ascribed to a tetragonal lattice system with I4/mcm space group. The dielectric attributes such as dielectric constant, electrical modulus, loss factor, and the DC, and AC conductivities, are observed to be varying appreciably with temperature over an extensive frequency window of 10 Hz–50 MHz. The Nyquist plots are investigated using the Maxwell–Wagner equivalent circuit model, which shows the impact of grains and grain boundaries on the overall impedance. Both the free charge conductivity and space charge increase with an increment in temperature, as revealed from the modified Cole–Cole plot. The relaxation time and relaxation mechanism of 2D CsPb2Br5 are estimated using the Kohlrausch–Williams–Watts equation. Variation in DC conductivity and relaxation time, as a function of temperature, closely resembles Arrhenius’ behavior. Value of activation energy calculated from the DC conductivity corroborates with the same derived from relaxation time. The observation of high dielectric constant and nominal dielectric loss for CsPb2Br5 perovskite offers enormous potential in energy harvesting and storage devices.
Proposal for measuring out-of-time-ordered correlators at finite temperature with coupled spin chains
Authors: Sundar Bhuvanesh , Elben Andreas , Joshi Lata Kh , Zache Torsten V 
Published: January 2022

Abstract
Information scrambling, which is the spread of local information through a system’s many-body degrees of freedom, is an intrinsic feature of many-body dynamics. In quantum systems, the out-of-time-ordered correlator (OTOC) quantifies information scrambling. Motivated by experiments that have measured the OTOC at infinite temperature and a theory proposal to measure the OTOC at finite temperature using the thermofield double state, we describe a protocol to measure the OTOC in a finite temperature spin chain that is realized approximately as one half of the ground state of two moderately-sized coupled spin chains. We consider a spin Hamiltonian with particle–hole symmetry, for which we show that the OTOC can be measured without needing sign-reversal of the Hamiltonian. We describe a protocol to mitigate errors in the estimated OTOC, arising from the finite approximation of the system to the thermofield double state. We show that our protocol is also robust to main sources of decoherence in experiments.
Variation of quantum speed limit under Markovian and non-Markovian noisy environment
Authors: Awasthi Natasha , Dheeraj Kumar Joshi , Sachdev Surbhi 
Published: January 2022

Abstract
The time required for a given quantum system to evolve is known as the quantum speed limit (QSL), which can be used to characterize the speed of evolution of a quantum system. We study QSL time for Markovian and non-Markovian dynamics. Investigating the effect of QSL under non-unitary evolution is of fundamental interest. In this work, we derive QSL time for maximally entangled state and apply its results under various noise channels. We discuss measure of QSL, how correlations affect the rate of QSL. Further, we carried an investigation on connection between non-Markovianity and QSL. We show that the non Markovian evolution can speed up quantum evolution, therefore lead to smaller QSL time. We have established the connections between correlated channels, information loss and non-Markovianity. This theory may suggest some further connections to retrieve back information from surrounding and preserves decoherence.

Authors: Fatimah Z , Susilawati  , Doyan A 
Published: January 2022

Abstract
BaCO3 with natural iron sand is the basic material for making samples of Barium M-Hexaferrite (BaM) which is doped to make the utilization of BaM more effective by adding metal ions that have almost the same size as cobalt (Co), copper (Cu), and Zinc (Zn) and using the coprecipitation method. The process of making Barium M-hexaferrite is carried out in the advanced and basic chemistry laboratory, FMIPA University of Mataram. In this study, variations in concentration and temperature variations during the calcination process were used, namely (x = 0.0; 0.4; 0.8; 1.0) (T = 200; 600; and 1000 °C). These variations greatly affect the sample, where the greater the concentration and temperature of calcination, the color produced in the sample will be darker and this is by the purpose of the calcination process carried out, namely the greater the temperature at the time of calcination, the more water content in the sample will be. reduced because the solvent in the sample evaporation occurs. In addition to these materials, the solvent used also plays an important role in the sample-making process, namely using HCl37% to dissolve, NH4OH 65% so that the deposition process is faster and aquades as a neutralizer.
