Chiral liquid crystal phases show fascinating structural and optical properties due to their inherent helical characteristics. Among the various chiral liquid crystal phases, the helical nanofilament phase, made of achiral bent-shaped molecules, has been of keen research interest due to its unusual polar and chiral pr…
In this work, the elastic moduli of silica based borotellurite glass system with compositional formula; [(TeO2)0.7 (B2O3)0.3]1-x (SiO2)x with x= 0.0, 0.1, 0.2, 0.3 and 0.4 was studied using theoretical models. Makishima and Mackenzie, bond compression, Rocherulle, and ring deformation models were employed in the calcu…
High Resolution Image Download MS PowerPoint Slide Commercial samples of strychnine sulfate were used as the starting material in crystallization experiments accompanied by stability studies. Eight hydrate forms ( HyA – HyG ), including five novel hydrates, were verified. The crystal structures of HyA (“pentahydrate”)…
Nanotechnology is one of the upcoming topics in the present era. Nanoparticles are synthesized by physical and chemical methods but limitations are due to their toxicity. Hence, green synthesis is more on demand which involves the use of plants, bacteria and fungi. In this review, copper nanoparticle synthesis is focu…
Designer nanoparticles with complex morphologies are of growing interest for a wide range of applications, but making them rationally and scalably remains challenging. Here, we demonstrate a retrosynthetic approach to access morphologically complex colloidal nanoparticles by combining partial sequential cation exchang…
In recent years, several tetracyanobuta-1,3-diene (TCBD) conjugates have been prepared by linking the tetracyano unit to various electroactive moieties. These push-pull conjugates, besides showing interesting physicochemical properties, are axially chiral, a feature arising from the restricted rotation around the cent…
Ca3Ti2O7 with a Ruddlesden–Popper structure has received great scientific attention due to its high ferroelectric polarization. However, the optimization of hybrid improper ferroelectricity is still a challenging issue. In the present work, the remarkably improved ferroelectric polarization has been achieved in B-site…
Six organic–inorganic hybrid pyridine-4-carboxylate-decorated organotin (OT)–lanthanide (Ln) heterometallic antimotungstates [Ln(H 2 O) 6 (pca)]H[Sn(CH 3 ) 2 (H 2 O)] 3 [B-β-SbW 9 O 33 ]·12H 2 O [Ln = La 3+ ( 1 ), Ce 3+ ( 2 ), Pr 3+ ( 3 ), Nd 3+ ( 4 ), Sm 3+ ( 5 ), Eu 3+ ( 6 ); Hpca = isonicotinic acid] have been prep…
The control of physical properties of soft matters via external stimuli is useful for various applications. Poly(ionic liquid)s are versatile liquid polymers exhibiting ionic conductivity, though the development of photoresponsive poly(ionic liquid)s is still limited. Here, we report the synthesis and properties of a…
It is very important for high photo-thermal conversion efficiency (HPTCE) that the optical property analysis, the contour map and optimized design of multilayer films for solar selective absorber are simulated and studied. With HPTCE of more than 96.38%, one SiO2/Cr/SiO2/Cr multilayer film fabricated by unbalance sput…
Austenitizing temperature is of great importance to achieve the desired properties of die steel. It governs the number of carbides dissolved in the austenitic matrix, which later transforms to martensite. This paper intends to find out the impact of austenitizing temperature on the wear behaviour of AISI H13 die steel…
Purpose: Enoxaparin has been widely used as a choice drug for treatment and prevention of different coagulation disorders. Orally administered enoxaparin encounters with gastrointestinal barrier because of its high water solubility, high molecular weight and significant negative charge. Since, the nano-liposomes has g…
This work investigates the thermal and mechanical performance of a bio‐inspired lightweight structure, which is inspired by the porous (up to 93% porosity) internal skeleton of cuttlefish, also known as cuttlebone. The potential of using this structure as an air‐cooled heat sink for electronic devices and an integrate…
Much research has focused on residual stress detection, analysis and elimination for alloy materials. There is however limited work considering residual stress in gray cast iron materials (HT200, 250, 300, 350) which are commonly used in heavy machine tool components. Herein an experimental program is undertaken to qu…
Photoluminescent carbon dots (C-dots) are widely used for bioimaging techniques to study different cellular processes. However, biocompatibility of C-dots is crucial because the wrong selection of C-dots may lead to an adverse effect on a particular cellular process. Herein, we investigate the interaction of zwitterio…
Large-area, flexible, two-dimensional transition metal dichalcogenide semiconductor materials (MoS2 and WSe2) were synthesized via magnetron sputtering of amorphous stoichiometric precursor materials on polydimethylsiloxane polymer substrates. Purely amorphous precursor materials and amorphous materials with pre-exist…
This article presents the numerical tests of thin-walled compressed columns with a square cross-section. The crush efficiency indicators were determined using the finite element method (Abaqus) and neural networks of MLP. The models had a constant circular trigger, with a diameter of 32 mm. During dynamic analysis, th…
Knowledge of negative thermal expansion (NTE) is an interesting issue in the field of materials science and engineering. It has been proposed that the unique dumbbell pairs of Fe (dumbbells) are highly entangled in the NTE behaviors of R 2 Fe 17 (R = rare earth) compounds but still remain controversial. Here, a facile…
Abstract Poly(ethylene terephthalate) (PET) cords are usually coated with epoxy and/or isocyanate solutions (like methylene diphenyl diisocyanate [MDI]) before resorcinol‐formaldehyde‐latex (RFL) to increase the adhesion efficiency of RFL. In this article, the addition of glycidyl polyhedral oligomeric silsesquioxane…
Abstract The thermoresponsive behavior of a poly(2-oxazoline)-based molecular brush is investigated in aqueous solution. The molecular brush under study, PiPOx100-g-PEtOx17, has a poly(2-isopropenyl-2-oxazoline) (PiPOx) backbone grafted with thermoresponsive poly(2-ethyl-2-oxazoline) (PEtOx) side chains. Since the bac…
