pH‐responsive polymers for drug delivery: Trends and opportunities
Authors: Singh Jagtar , Nayak Pallavi 
Published: August 2023

AbstractPolymer science has applications in biomedical engineering, prosthetics, surgical implants, and prospective pharmaceutical excipients for drug delivery. “Intelligent or Smart Polymers” are created for drug targeting either by derivatization of natural polymers or controlled radical polymerization of electrolytes. Their mode of action is governed by the environmental stimuli viz. temperature, pH, ionic concentration, magnetism, and so on. pH‐responsive polymers, because of their self‐assembling behavior, alter their solubility, conformation, surface activity, and hydrophilicity when exposed to a specific pH. The physiological pH varies from acidic nuclei to alkaline cytoplasm and highly acidic gastric juice to slightly alkaline plasma; thus, various polymers are under study for delivering small molecules, genes, peptides, enzymes, growth factors, and antibodies. The non‐invasive drug delivery routes like oral, ocular, nasal, pulmonary, transdermal, and rectal routes can be explored for targeting recombinant proteins, monoclonal antibodies, and small molecules with particular emphasis on the individual's physiological and pathological state. Further, these polymers can be designed into various architectures like dendrimers, liposomes, micelles, and metallic nanoparticles that can serve as drug reservoirs for sustaining drug release. The challenges in this field are the selection of biocompatible polymers with ease of synthesis and scale‐up, ensuring effective drug‐loading, and stability aspects, producing robust pharmacological data, and timely regulatory approvals. This review exclusively explores the physicochemical characteristics of pH‐responsive polymers, their categorization, various architectural entities, recent studies and patents, and their emerging applications concerning specific diseases.
Solid propellants: A first‐principles study of nitrous oxide generation from A3
Authors: Shen Lan , Yao Zihao , Deng Shengwei , Wang Shibin , Mao Chengli , Wang Jian‐Guo 
Published: August 2023

AbstractDensity functional theory (DFT) is used to calculate and study the reaction mechanism of the four equations of nitrous oxide generation from plasticizer A3 (BDNPF: BDNPA=1 : 1). The optimal pathway is found for each equation, and finally, an optimal total pathway is found. At the same time, HONO is generated from A3 degradation. The stability is evaluated through ab‐initio molecular dynamics simulation (AIMD), and the electronic structure is analyzed to determine the active sites. The decomposition of A3 accelerates the aging of solid rocket propellant. Therefore, the mechanism of nitrous oxide generation from A3 can be revealed through various theoretical methods, which is of great significance for the subsequent slowing down of the aging of solid propellant.
APTMS‐Modified Silica as a Thin‐Film Nanocomposite Forward Osmosis Membranes: Towards Enhanced Selectivity and Dye Rejection Stability for Congo Red and Rhodamine B

Published: August 2023

AbstractFumed silica (SiO2) is often applied in the modification of thin‐film composite (TFC) forward osmosis (FO) membranes due to its hydrophilicity. However, a key challenge to be solved is to improve its compatibility with organic matrices and dispersion in the material. In this study, we synthesized well‐designed nanoparticles of (3‐aminopropyl)trimethoxysilane‐modified SiO2 (APTMS‐SiO2) and applied them for the first time in the preparation of FO membranes. Furthermore, we systematically investigated the effects of different pretreated SiO2, SiO2 dosages, draw solution types, and concentrations on FO membranes. The results showed that APTMS‐SiO2 thin‐film nanocomposite with a silica dosage of 0.1 wt.% has the highest water permeate flux (Jw) (26.25 LMH, 370.43 % higher than the control TFC of 5.58 LMH) and the minimum specific reverse solute flux (SRSF) of 0.17 g/L with 1 M NaCl as the draw. The incorporation of APTMS effectively prevented mutual agglomeration of SiO2 and improved its dispersion. The Jw of 13.36 LMH after seven cycles and the rejection of above 96.6 % for Congo Red and 95.8 % for Rhodamine B indicated potential reusability and dye rejection. This work presents an alternative approach to prepare FO membranes with enhanced water flux and increased selectivity, and it also offers insights for the treatment of printing and dyeing wastewater using FO.
Synthesis of Modified River Clay Catalyst for Valuable BTE Production via Catalytic Pyrolysis of Hazardous Plastic Waste
Authors: Verma Anjali , Pramanik Hiralal 
Published: August 2023

AbstractIn the present study, silica‐alumina rich river clay calcined at different temperatures are used as low cost natural green catalyst for the production of valuable aromatics benzene, toluene and ethylbenzene (BTE) via multiphase/Mp‐type catalytic pyrolysis of waste expanded polystyrene (WEPS). The calcined river clay catalysts are designated as RHC‐600, RHC‐700, RHC‐800 and RHC‐900 after calcination at the temperature of 600 °C, 700 °C, 800 °C, and 900 °C, respectively. Whereas, the natural river harvested clay is designated as RHC. The RHC‐800 catalyst is found to be the best catalyst for the WEPS pyrolysis due to its highest surface area of 18.83 m2/g and high silica to alumina (Si/Al) ratio of 2.23 among all other river harvested clay catalysts. The styrene content get reduced from 84.74 wt.% to 65.30 wt.% and BTE content increased from 11.38 wt.% to 23.51 wt.% when the process is switched over from thermal to Mp‐type catalytic pyrolysis using RHC‐800 catalyst. The promising results of RHC‐800 indicate that it can be an alternative to commercial catalyst for pyrolysis applications.
Highly Stretchable and Highly Conductive Organic Transparent Conductors Based on Aqueous‐Processable Conducting Polymer/Ionic Liquid Composites
Authors: Kee Seyoung 
Published: August 2023

AbstractDeformable (semi)conducting polymers have attracted great attention for realizing next‐generation wearable and stretchable electronics. A conductive π‐conjugated polymer, poly(3,4‐ethylenedioxythiophene) : poly(styrenesulfonate) (PEDOT : PSS) is considered as a key component based on the promising electrical characteristics and aqueous processability. However, the general trade‐off relationship between electrical and mechanical performance in PEDOT : PSS is a crucial issue for its practical application as a stretchable conductor. Herein, a simultaneous improvement in electrical conductivity and mechanical stretchability was achieved from PEDOT : PSS by introducing a water‐soluble ionic liquid, 1‐ethyl‐3‐methylimidazolium dicyanoimidazolate (EMIM : DCIM). The electromechanical improvement is closely related with the EMIM : DCIM contents, in which EMIM : DCIM not only causes a morphological transition but also acts as a plasticizing agent. As a result, highly stretchable and highly conductive PEDOT : PSS/EMIM : DCIM composites were obtained with an initial electrical conductivity of ≈550 S cm−1 and maximum strain of 70 % while maintaining the initial electrical properties. Finally, a potential application of PEDOT : PSS/EMIM : DCIM as a stretchable transparent conductor was successfully demonstrated with given high visible transparency and eco‐friendly processability.

Published: August 2023

AbstractThis study was aimed to synthesise antimicrobial and therapeutic silver nanoparticles (AgNPs) by green synthesis method using Vitex agnus‐castus L. (VAC) seed extract. The synthesised VAC seed extract coated AgNPs were characterised by UV‐Vis spectrometry, Zeta analysis and FT‐IR spectrometry. The antifungal, antimicrobial, cytotoxicity by MTT assay, and anticarcinogenic activities on HeLa cells line were investigated. VAC‐AgNPs exhibited high antimicrobial activity against S. aureus with a zone diameter of 11.3±0.6 mm. In addition, the cytotoxicity of VAC‐AgNPs was evaluated using the L929 fibroblast cell line and the HeLa cells line, with AgNPs applied at six different concentrations. At a concentration of 5.0 mM, viability was found to be 47.6 %±4.2 % in L929 fibroblast cells and 39.6 %±7.9 % in HeLa cells, suggesting a potential antiproliferative effect of VAC‐AgNPs on HeLa cancer cells. The IC50 values of VAC‐AgNPs against the HeLa cell line were calculated as 2.94 μg/ml.

Authors: Habibi Biuck , Farhadi Khalil , Minaie Elnaz 
Published: August 2023

AbstractA new nanocomposite containing Ni(II) ions, electrochemically reduced graphene oxide (ERGO) and poly (p‐aminobenzenesulfonic acid) (Pp‐ABSA) on pencil graphite electrode (PGE) was prepared using electrochemical deposition coupled with self‐assembly accumulation method and characterized with different techniques. The electrochemical behavior and electrocatalytic activity of modified PGEs were investigated. The Ni/Pp‐ABSA/ERGO/PGE showed a unique electrocatalytic oxidation through an Electrochemical‐Chemical (EC’) pathway for methanol in alkaline media (Jpf=7.04 mA cm−2 and Eonest=0.38 V) compared to Ni/PGE, Ni/Pp‐ABSA/PGE and Ni/ERGO/PGE. The obtained results showed that the self‐assembled incorporation of Ni(II) ions in Pp‐ABSA/ERGO film prepared on PGE surface produced a stable modifier with high electrocatalytic activity towards methanol oxidation. In conclusion, the introduced method for the preparation of Pp‐ABSA/ERGO‐based nanocomposites can open a new, cheap and simple way to design a high‐performance electrocatalyst for direct methanol fuel cell systems.
A review on plankton as a bioindicator: A promising tool for monitoring water quality

Published: August 2023

AbstractBioindicators have become increasingly popular and have contributed significant amounts of useful information to the process of managing water resources. The ability of a species (or species assemblage) to adapt to a certain range of chemical, physical, and biological conditions is one criterion that can be used to assess the quality of its surrounding environment. Planktons that react quickly to changes in their environment have proven to be particularly valuable, and the identification of certain indicator species has become increasingly common in the process of determining the quality of the water. The “health” of an aquatic system can be inferred from the presence or absence of plankton, which act as early warning signals. When compared with the expense of assessing harmful contaminants, the overall cost of conducting routine monitoring of biological communities is far lower and has a higher degree of reliability. The ability of bioindicators to identify indirect biotic effects of pollutants, which is something that many physical or chemical tests are unable to do, is another advantage of using bioindicators. Different aquatic species as bioindicators tolerate different environmental conditions, and their different tolerances to particular environments help in identifying a particular environmental condition. Phytoplankton species like Euglena viridis, Oscillatoria limosa, Nitzschia palea, and Scenedesmus quadricauda, and zooplankton species like Branchionus sp., Molina sp., Keratella cochlearis, Daphnia sp., and Cyclopus sp. indicate water pollution. This review's objective is to highlight some recent research on planktons, focusing on their capabilities and opportunities for application as bioindicators of water quality.
Brief Description of Prestressed Concrete Structures
Authors: Wang Lei 
Published: August 2023

AbstractStrand corrosion can cause concrete cracking, degrade bond performance at the strand–concrete interface, lead to prestress loss, and deteriorate the capacity of prestressed concrete structures. This book clarifies the mechanical behavior of corroded prestressing strands, corrosion-induced cracking, bond degradation, prestress loss, and structural performance deterioration of prestressed concrete structures and proposes the corresponding prediction models, which has an important guidance for the durability and maintenance design of prestressed concrete structures.
Corrosion-Induced Cracking of Prestressed Concrete
Authors: Wang Lei 
Published: August 2023

AbstractStrand corrosion can cause the cracking of prestressed concrete. In this chapter, the concrete cracking caused by strand corrosion under different prestress is experimentally studied. Then, a theoretical model, incorporating the coupled effects of prestress and strand corrosion, is proposed to predict the global process of prestressed concrete cracking. Following this, a meso-scale numerical model is established to simulate concrete cracking induced by the three-dimensional corrosion expansion of helical strands.
Flexural Behaviors of Corroded Post-tensioned Concrete Beams
Authors: Wang Lei 
Published: August 2023

AbstractThe insufficient grouting and strand corrosion can affect the flexural behavior of prestressed concrete beams. An experimental study with twenty prestressed concrete beams is designed to study the effect of grouting defects and strand corrosion on the flexural performance of prestressed concrete beams. Corrosion effects on concrete cracking, post-cracking stiffness, ultimate strength, failure mode, and ductility are then clarified by the flexural test, and a coefficient is introduced to quantify the incompatible strain between corroded strand and concrete.

Abstract
We measure the cross section of e+e− → ηcJ/ψ at the Υ(nS)(n = 1–5) on-resonance and 10.52 GeV off-resonance energy points using the full data sample collected by the Belle detector with an integrated luminosity of 955 fb−1. We also search for double charmonium production in e+e− → ηcJ/ψ via initial state radiation near the ηcJ/ψ threshold. No evident signal of the double charmonium state is found, but evidence for the e+e−→ ηcJ/ψ process is found with a statistical significance greater than 3.3σ near the ηcJ/ψ threshold. The average cross section near the threshold is measured and upper limits of cross sections are set for other regions.
De Sitter versus Anti de Sitter flows and the (super)gravity landscape
Authors: Kiritsis Elias , Tsouros Alexandros 
Published: August 2023

Abstract
Generic solutions are studied in Einstein-scalar gravity in an ansatz that can interpolate between de Sitter and Anti-de Sitter regimes. The classification of regular solutions of [1, 2] is first extended to the dS regime. This implies, among others, the existence of cosmic clocks that reverse direction without passing through a curvature singularity. We then consider an ansatz for solutions that interpolate between the dS and AdS regimes. The structure of such more general solutions and their singularities are studied. It is shown that there are no regular solutions that interpolate between dS and AdS extrema for generic potentials. This is unlike the Centaur solutions that were shown to exist in two bulk dimensions. We also comment on the potential interplay with recent dS conjectures and the dS BF bounds.
A twisted tale of the transverse-mass tail
Authors: Bandyopadhyay Triparno , Budhraja Ankita , Mukherjee Samadrita , Roy Tuhin S. 
Published: August 2023

Abstract
We propose a tantalizing possibility that misinterpretation of the reconstructed missing momentum may have yielded the observed discrepancies among measurements of the W-mass in different collider experiments. We introduce a proof-of-principle scenario characterized by a new physics particle, which can be produced associated with the W-boson in hadron collisions and contributes to the net missing momentum observed in a detector. We show that these exotic events pass the selection criteria imposed by various collaborations at reasonably high rates. Consequently, in the presence of even a handful of these events, a fit based on the ansatz that the missing momentum is primarily due to neutrinos (as it happens in the Standard Model), yields a W-boson mass that differs from its true value. Moreover, the best fit mass depends on the nature of the collider and the center-of-mass energy of collisions. We construct a barebones model that demonstrates this possibility quantitatively while satisfying current constraints. Interestingly, we find that the nature of the new physics particle and its interactions appear as a variation of the physics of Axion-like particles after a field redefinition.
Aspects of dynamical cobordism in AdS/CFT
Authors: Huertas Jesús , Uranga Angel M. 
Published: August 2023

Abstract
The cobordism conjecture implies that consistent theories of Quantum Gravity must admit the introduction of boundaries. We study the dynamical realization of the cobordism conjecture in type IIB in AdS5 × S5, using the existing gravity duals of 4d 𝒩 = 4 SYM with Gaiotto-Witten superconformal boundary conditions (near-horizon limits of D3-branes ending on NS5- and D5-branes). We show that these configurations are, from the 5d perspective, dynamical cobordism solutions which start from an asymptotic AdS5 vacuum and evolve until they hit an end of the world (ETW) brane with AdS4 worldvolume. The latter displays localization of gravity, and provide a completion of the Karch-Randall (KR) AdS branes, in which the backreaction of running scalars replace the KR cusp in the warp factor with a smooth bump. The dynamical scalars are either in the SO(6) invariant AdS5 bulk sector (e.g. describing the S5 size and its shrinking at the cobordism boundary) or brane localized (e.g. the SO(6) SO(3) × SO(3) squashing due to boundary conditions). We introduce a novel double scaling limit which zooms into the ETW brane and makes localization of gravity manifest, and which shows a tantalizing relation with wedge holography. We extend the picture to AdS5 theories with less (super)symmetry, via orbifolds and S-folds, leading to dynamical cobordisms for gravity duals of 4d theories with 𝒩 = 2 and 𝒩 = 3 supersymmetry.
Bell violation in 2 → 2 scattering in photon, gluon and graviton EFTs
Authors: Ghosh Diptimoy , Sharma Rajat 
Published: August 2023

Abstract
In this paper, we explore Bell inequality violation for 2 → 2 scattering in Effective Field Theories (EFTs) of photons, gluons, and gravitons. Using the CGLMP Bell parameter (I2), we show that, starting from an appropriate initial non-product state, the Bell inequality can always be violated in the final state (i.e.,I2> 2) at least for some scattering angle. For an initial product state, we demonstrate that abelian gauge theories behave qualitatively differently than non-abelian gauge theories (or Gravity) from the point of view of Bell violation in the final state: in the non-abelian case, Bell violation (I2> 2) is never possible within the validity of EFTs for weakly coupled UV completions. Interestingly, we also find that, for a maximally entangled initial state, scattering can reduce the degree of entanglement only for CP-violating theories. Thus Bell violation in 2 → 2 scattering can, in principle, be used to classify CP conserving vs violating theories.
A new LHC search for dark matter produced via heavy Higgs bosons using simplified models

Published: August 2023

Abstract
Searches for dark matter produced via scalar resonances in final states consisting of Standard Model (SM) particles and missing transverse momentum are of high relevance at the LHC. Motivated by dark-matter portal models, most existing searches are optimized for unbalanced decay topologies for which the missing momentum recoils against the visible SM particles. In this work, we show that existing searches are also sensitive to a wider class of models, which we characterize by a recently presented simplified model framework. We point out that searches for models with a balanced decay topology can be further improved with more dedicated analysis strategies. For this study, we investigate the feasibility of a new search for bottom-quark associated neutral Higgs production with a $$ b\overline{b}Z+{p}_{\textrm{T}}^{\textrm{miss}} $$

Our projected results in the different simplified model topologies investigated here can be easily reinterpreted in a wide range of models of physics beyond the SM, which we explicitly demonstrate for the example of the Two-Higgs-Doublet model with an additional pseudoscalar Higgs boson.
