More than a century after the discovery of the electron, there are still fundamental, yet unresolved, questions concerning the generation-ejection mechanism of the ubiquitous Secondary Electrons (SEs) from a solid surface. Broadness of the field of application for these SEs makes it desirable to be able to control thi…
Triangular silver nanoplates synthesized using conventional method with trisodium citrate as capping agent shows degradation of its sharp edges over a period of time making them suitable for use only in a limited time-frame. In this work, we present a new approach to synthesize triangular nanoplates using seed mediate…
Prostate cancer (PCa) is a worldwide issue, with a rapid increase in its occurrence and mortality. Over the years, various strategies have been implemented to overcome the hurdles that exist in the treatment of PCa. Consistently, there is a change in opinion about the methodologies in clinical trial that have engrosse…
A study of the influence of polyols, with or without an additional reducing agent, on crystallites’ size and magnetic features in Fe3O4 nanoparticles and on their performance in magnetic particle hyperthermia is presented. Three different samples were synthesized by thermal decomposition of an iron precursor in the pr…
Over two years we assessed silver-containing nanoparticles (SCN) and total silver in the in- and effluent of a wastewater treatment plant (WWTP) discharging purified wastewater into a lake. Additionally, total silver was measured in sludge of the WWTP and in water, sediment, and fish of the receiving lake at several p…
In an effort to improve the surface properties of electrical contact materials in terms of high friction coefficient and wear rate, diamond-like carbon (DLC) films containing different metal elements were prepared on stainless steel substrates using an unbalanced magnetron sputtering system. In the present study, the…
We fabricated few-layer, multilayer, and mixed-thickness rhenium disulfide (ReS 2 ) based on a vertical van der Waals n–p junction for photosensing applications. ReS 2 flake deposition onto a p +2 Si substrate led to the formation of a n–p heterojunction with rectifying characteristics and good photosensing ability un…
Grain boundaries (GBs) of transition metal dichalcogenide monolayers (MLs) play an important role in many charge transport phenomena observed in 2D materials. Herein, nanoscale resolution current mapping by conductive atomic force microscopy (CAFM) is used for direct probing of the resistance associated with GBs in ML…
In ``rainbow trapping'', waves of different wavelengths are spatially separated, which is interesting for $e.g.$ optical buffers, multiplexers, and energy harvesting. It is difficult to realize such trapping without reflections, though. Unlike previous designs, this study proposes a hybrid metamaterial--transmission-l…
Extrinsically controlling the intrinsic activity and stability of two-dimensional (2D) semiconducting materials by substitutional doping is crucial for energy-related applications. However, an in situ transition-metal doping strategy for uniform and large-area chemical vapor deposited 2D semiconductors remains a formi…
In recent years, material scientists have been focusing on the utilization of materials from natural resources due to environmental concerns. In the same context, the aim of this work is to evaluate impact response, sound absorption behavior, and vibration damping characteristics of natural-based composite sandwich ma…
Glasses Al 2/3 O–TeO 2, ZnO–TeO 2 and R 2/3 O–ZnO–TeO 2 (R = Al, B) were prepared by melting in Pt crucibles and studied for correlations between structure and thermal as well as mechanical properties, whereby the glass composition is varied to tailor the short-range speciation of tellurite, aluminate, and borate grou…
Composite i-PP/PEDOT films made of isotactic polypropylene (i-PP), which is frequently used for the fabrication of implantable medical devices for internal use, and chemically synthesized poly(3,4-ethylendioxythiophene) (PEDOT) nanoparticles, which are electroactive and biocompatible, have been prepared and used to de…
Two-dimensional (2D) cadmium chalcogenide (CdX, X = Se, S, Te) colloidal nanoplatelets (NPLs) make up an emerging class of quantum well materials that exhibit many unique properties including uniform quantum confinement, narrow thickness distribution, large exciton binding energy, giant oscillator strength, long Auger…
Abstract The Eu 3+ ‐doped (1 − x)Na 0.5 Bi 0.5 TiO 3 ‐ x SrTiO 3 (Eu‐NBT‐ x STO) thin films were prepared on Pt/Ti/SiO 2 /Si substrates. Raman analysis reveals that the phase structure may undergo a phase evolution of rhombohedral → rhombohedral + tetragonal (morphotropic phase boundary) → tetragonal with increasing c…
We investigated the two-step chemical transformation of a series of symmetric poly(styrene- b -solketal acrylate) (PS- b -PSA) copolymers with varying molecular weights from 1900 to 27 300 g/mol (13 ≤ N ≤ 194) synthesized by sequential atom transfer radical polymerization. Through acid-catalyzed hydrolysis, the PSA bl…
The work involves fabrication of natural fibre/Elium® composites using resin infusion technique. The jute fabrics were treated using phosphorus-carbon based flame retardant (FR) agent, a phosphonate solution and graphene nano-platelet (GnP), followed by resin infusion, to produce FR and graphene-based composites. The…
Cheaper methods and raw materials are currently being sought for the production of microfibrillated cellulose. Presently microfibrils with high lignin content have attracted increasing interest. Wood residues, like sawdust, are good candidates due to their abundancy and low price but the recalcitrant nature of the lig…
Two simple methods are proposed to respectively impart external force-free reversible shape memory effect to commercial polyolefins: ultrahigh molecular weight polyethylene (UHMWPE) and polypropylene (PP). The key issues lie in the utilization of the partially entangled molecular chains of UHMWPE and the medium crysta…
Composite structures exhibiting a periodic arrangement of building blocks can be found in natural systems at different length scales. Recreating such systems in artificial composites using the principles of self-assembly has been a great challenge, especially for 1D microscale systems. Here, we present a purposely des…
