Chitosan-catechol conjugates are a novel class of bioadhesive polymers which are used in specific/target drug delivery systems to bind the drug to the mucosal lining. Preparation of chitosan-catechol conjugates by chemical, electrochemical and enzymatic methods has been discussed. Different characterization techniques…
Molecular optimization, which transforms a given input molecule X into another Y with desirable properties, is essential in molecular drug discovery. The traditional translating approaches, generating the molecular graphs from scratch by adding some substructures piece by piece, prone to error because of the large set…
Abstract Atomistic models provide a detailed representation of molecular systems, but are sometimes inadequate for simulations of large systems over long timescales. Coarse-grained models enable accelerated simulations by reducing the number of degrees of freedom, at the cost of reduced accuracy. New optimisation proc…
Functional finishing and surface functionalization play an ever-increasing role in the design of functional textiles for, e.g., technical and industrial applications. Surface treatments impart chemical modifications to the fiber surface that affect the surface free energy, either with the aim to alter the wetting beha…
The control of ubiquitous wetting behavior that is determined by the surface free energy of the solid and the surface tension of the interacting liquid is an area of intense research, largely due to its applications in various sectors, ranging from healthcare to automotive industry. The failure and/or toxic nature of…
We retract this manuscript because of calculational errors on the mechanical properties of pentadiamond. Based on feedback from several groups (see below), we carefully rechecked the mechanical properties and found serious mistakes in the optimized structure of pentadiamond under mechanical deformation. Our new calcul…
Composite prosthetic sockets are typically made of fiberglass or carbon fiber. These fibers have good mechanical properties, but relatively poor vibration damping. Flax fibers are claimed to have exceptional vibration damping properties, with the added benefit of being a natural renewable resource and a cost-effective…
One of the primary factors limiting further research and the commercial use of the two-dimensional (2D) MXene titanium carbide (Ti3C2), as well as MXenes in general, is the rate at which freshly made samples oxidize and degrade when stored as aqueous suspensions. Here, we show that including excess aluminum during syn…
Adhesive bonding is a viable technique for joining a wide range of materials (e.g. metals, polymers, ceramics, etc., and combinations of any of these materials). However, one disadvantage of adhesive bonding is the permanent character of the joint. In many situations, it is desirable that the joint can be separated so…

Graphite nanoplatelets (GNPs) were produced from flake graphite that had been immersed in isopropyl alcohol solution (70%) and converted to powder form in an ultrasonic bath (5 h, room temperature). Scanning and transmission electron microscopy, X-ray diffractometry, and Raman spectroscopy identified 120-nm-thick GNP…
The Front Cover shows the incorporation of Ni in the RuO2-based supercapacitor through a simple electrochemical process. Nickel incorporation affects both the morphology and electrochemical performance, particularly enabling operation of the supercapacitor in high current densities and high frequencies. More informati…
Currently, studies about the CO2 gas injection improve the production efficiency of crude oil. The surface interaction between CO2 and thin films is a large area of research in the scientific community. In this work, we are showing that The TiZrN (coating) + Si (substrate) system immersed on environments of fully CO2…
This article focused on further investigation of passive vibration damping of a cantilever plate using carbon nanotube/epoxy nanocomposite. A damping ratio depends on many factors, for example carbon nanotube content, type of carbon nanotubes, and frequency, so the epoxy composite reinforced with 0.2 wt. % multi-wall…
KHNP recently has obtained the approval for the commercialization of the modified 37-element (or 37 M) fuel bundle and now is loading the 37 M fuel bundles in CANDU-6 reactors in KOREA. One of the main issues for approval was the burnup limit. Due to CANDU design and neutronic characteristics, there was no specific bu…
Abstract Molybdenum dioxide (MoO 2 ) has attracted lots of theoretical interest as an anode material for sodium ion batteries (SIBs) due to its high theoretical capacity (836 mA h g −1 ) and metallic electrical conductivity (1.9 × 10 2 S cm −1 ). The insertion reaction, forming Na 0.98 MoO 2 and the reversible convers…

The filtering of overlapping spectral regions may be used to increase the observer’s gamut in some cases. Therefore, metasurface-based contact lenses (M-CL) may improve the color coding for specific stimuli and deuteranomaly conditions. Here, we address the concerns made by Huertas et al. [ Opt. Lett. 45 , 5117 ( 2020…
Abstract Invited for this month's cover picture is the group of Prof. Raz Jelinek at Ben‐Gurion University. The cover picture shows the incorporation of Ni in the RuO2‐based supercapacitor through a simple electrochemical process. Nickel incorporation affected both the morphology and electrochemical performance, parti…
