Development of molecular beam epitaxy (MBE) of two-dimensional (2D) layered materials is an inevitable step in realizing novel devices based on 2D materials and heterostructures. However, due to existence of numerous polytypes and occurrence of additional phases, the synthesis of 2D films remains a difficult task. Thi…
A volatile organic compound (VOC)-free method for the synthesis of poly(hydroxyurethane)–(meth)acrylic waterborne hybrid dispersions was developed. Poly(hydroxyurethane) (PHU) synthesized by bulk aminolysis of cyclic-carbonate derivatives using biosourced vegetable oil-based diamines was dissolved in (meth)acrylate mo…
The vital functions of cell membranes require their ability to quickly change shape to perform complex tasks such as motion, division, endocytosis, and apoptosis. Membrane curvature in cells is modulated by very complex processes such as changes in lipid composition, the oligomerization of curvature-scaffolding protei…
Photodynamic therapy (PDT) has greatly been hindered by its extreme dependence on oxygen, undesired local photodamage, and a shallow tissue penetration depth. Chemotherapy always encounters obstacle of the uncontrolled premature release of drugs. Here, we developed a novel α-NaYbF 4:Tm@CaF 2:Nd@ZnO–PAA–DOX (named as U…
Negative thermal expansion (NTE) plays an increasingly important role in the control of thermal expansion of materials. However, the discovery of strong NTE materials, which is rare, remains challenging. In this study, a strong NTE (α l = −14.01 × 10 –6 K –1 ) has been achieved in La(Fe 11.5 Al 1.5 ) by a new method o…
To overcome the obstacle of anti-cancer therapy significant attention has been drawn for improving drug delivery system. Since recent past, different approaches were applied using synthetic or natural derivatives for improving efficacy of anti-cancer drugs in cancer therapeutics. Gallic acid (GA) is a natural polyphen…
The growing need for sustainable technologies has attracted considerable interest in the synthesis of ecofriendly materials. This paper reports the anti-inflammatory and antibacterial activities of sustainable silver nanoparticles (AgNPs) fabricated using endophytic fungus extracted from a medicinal plant, Cassia fist…
Purpose: In this study, leaf/flower aqueous extract of medicinal plant species Mentha pulegium was used to synthesize ZnO and CuO nanoparticles (NPs) as a cost-effective, one-step, and eco-friendly method. Methods: Physicochemical properties of both metal oxide NPs (MONPs) were determined by UV-Vis spectroscopy, X-Ray…
Lung cancer has the highest mortality of any cancer worldwide, and cisplatin is a first-line chemotherapeutic agent for lung cancer treatment. Unfortunately, cisplatin resistance is a common cause of therapeutic failure. The ability to overcome chemoresistance is crucial to the effective treatment of lung cancer. Rece…
The aim of this study was to investigate the effect of recycling on polypropylene (PP) and wood-fiber thermoplastic composites (WPCs) using a co-rotating twin-screw extruder. After nine extrusion passes microscopy studies confirmed that the fiber length decreased with the increased number of recycling passes but the i…
Abstract The synthesis, structure, magnetic, and luminescence properties investigations of four new cage‐like lanthanide‐based silsesquioxanes (Cat)2[(PhSiO1.5)8(LnO1.5)4(O)(NO2.5)6(EtOH)2(MeCN)2] (where Cat+=Et4N+, PPh4P+ and Ln3+=Eu3+, Tb3+ and (Ph4P)4[(PhSiO1.5)8(TbO1.5)4(O)2(NO2.5)8]⋅10MeCN are reported. They pres…
Green nanotechnology is relatively new branch of science and technology with many interesting applications. This technology involves in the synthesis of inorganic nanoparticles (NPs) through green synthesis using extracts of plant-derived materials. Green synthesis of metal and metal oxide NPs is a good alternative ov…
Abstract Structural colors obtained by self‐organized microstructures have found a variety of applications, such as decorations, displays, and encryption microarrays, and have been widely investigated for the excellent stability and anisotropic optical responses upon external stimuli. Here, the fabrication of a variet…
Abstract Selective-area remote epitaxy (SA-REpi) is demonstrated for fabricating mechanically releasable position-controlled ZnO microrod (MR) arrays from donor wafers in an arrayed form. Intaglio-patterned graphene, consisting of basal single-layer graphene (SLG) overlayered with multilayer graphene (MLG) patterned w…
Abstract The composites based on polylactide (PLA) and poly (3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) with the addition of antibacterial particles: silver (Ag) and copper oxide (CuO) are characterized. Basic mechanical properties and biodegradation processes, as well as biocompatibility of materials with human c…
Free-standing ultrathin (∼2 nm) films of several oxides (Al 2 O 3,TiO 2, and others) have been developed, which are mechanically robust and transparent to electrons with E kin ≥ 200 eV and to photons. We demonstrate their applicability in environmental X-ray photoelectron and infrared spectroscopy for molecular level…
Metal-oxide-based electrodes play a crucial role in various transparent conductive oxide (TCO) applications. Among the p-type materials, nickel oxide is a promising electrically conductive material due to its good stability, large bandgap, and deep valence band. Here, we display pristine and 3 at.%V-doped NiO synthesi…
Cellulose nanocrystals (CNCs) are promising materials for the packaging industry due to their nontoxicity, abundance in nature, biodegradability, and high gas barrier properties. Unfortunately, CNC barrier films and coatings suffer from brittleness, water sensitivity, and, similar to polar polymers, loss of barrier pe…
The deposition of layers of different polycations (synthetic or derived from natural, renewable resources) onto oppositely charged surfaces has been studied using ellipsometry and quartz crystal microbalance with dissipation monitoring (QCM-D). Information about the thickness of the deposited layers and their water co…
