A newly-designed drug carrier with enzyme-triggered release behavior and the ability to circumvent multidrug resistance was successfully developed. By optimizing the ratio of lecithin and polysaccharide in reverse micelles, encapsulation efficiency and encapsulation stability can be significantly improved.
The structure of hydrated Co ions confined in the nanospace of single-walled carbon nanotubes (SWNTs) has been studied using the X-ray absorption fine structure (XAFS) technique. Water adsorption isotherms on Co-impregnated SWNTs indicate a high affinity of Co ions to water molecules. The results of XAFS analysis prov…
Cat's claw oxindole alkaloids are prone to isomerization in aqueous solution. However, studies on their behavior in extraction processes are scarce. This paper addressed the issue by considering five commonly used extraction processes. Unlike dynamic maceration (DM) and ultrasound-assisted extraction, substantial isom…
Using a facile method, Fe/Mo anti-site defect (ASD) concentration in double perovskite Sr2FeMoO6 is quantitatively controlled within a wide range of 2%–21%. Our systematic investigation demonstrates the significant effects of ASD on the physical properties, such as magnetization, magnetoresistance and the Curie temper…
An all-dielectric carpet cloak, formulated using the optical transformation technique, is presented here. The carpet cloak was fabricated by implementing a dielectric disk matrix (DDM) with varying periods. To demonstrate that it is functional for multiple angles of incidence, the cloak is measured in a near-field sca…
This mini-review highlights the recent advances in the photosensitized electron-transfer processes of nanocarbons decorated with electron-donating or electron-accepting photosensitizer molecules. As nanocarbons, well-characterized fullerenes, size (diameter)-sorted single wall carbon nanotubes (SWCNTs), few-layer grap…
In this paper, a simple and stable composite electrode based on intrinsically conducting polymer poly(3,4-ethylenedioxythiophene):poly(sty-renesulfonate) (PEDOT:PSS) and ion-exchange polymer Nafion, was successfully fabricated by drop-coating the blended commercially available PEDOT:PSS aqueous dispersion and Nafion s…
This study aims to use sweet sorghum juice (SSJ) to produce an environmentally friendly biopolymer of polyhydroxyalkanoates (PHAs) by bacteria isolated from soil. Among 18 isolates, only 3 isolates, coded as S4, S6, and S11, were chosen to produce PHA via batch fermentation compared to 3 strains of Alcaligenes eutroph…
To promote possible applications of graphene in molecular identification based on stacking effects, in particular in recognizing aromatic amino acids and even sequencing nucleobases in life sciences, we comprehensively study the interaction between graphene segments and different cyclic organic hydrocarbons including…
The traditional concept of the synthesis of semiconductor nanocrystals (NCs) by solvent routes usually performed under high temperatures, causes the semiconductor materials to nucleate and grow into various shaped NCs in solution. Therefore, these methods are named as “solvent-thermal approachs”. In this work, we desc…
porphyrin were synthesized in the 3 solvents mixture by Adler-Longo method. The porphyrin purification was carried out by ethyl acetate extraction.
Two 2D silver lamella frameworks, [Ag4(C5H4NS)2(NO3)2]n (1) and [Ag3(C5H4NS)2]n·nClO4 (2) based on binuclear units have been solvothermally synthesized. The C5H4NS ligand was in situ generated from the cleavage of bis(2,4,6-trimethyl-3,5-bis((pyridin-2-ylthio)methyl)phenyl)methane (bmpm). Furthermore, the formation of…
A solid phase preconcentration procedure using SBA‐3 nanosorbent for the fast separation and preconcentration of crystal violet (CV) in water samples by fiber optic‐linear array detection spectrophotometry (FO‐LADS) is presented. Experimental parameters including pH, sample volume, amount of sorbent, type, volume, and…
Issues of doing research, designing high performance concrete compositions, optimal application of this material as in the field of erecting unique buildings and constructions, so in large-scale construction, are discussed in the article. Requirements to high performance concrete are set; the existing practice of its…
Here we report on our investigations into the aggregation behaviour and optoelectronic properties of organic (semi)conductor-containing π-conjugated rod–coil–rod triblock materials. The facile synthesis of these rod-like tetra(aniline) (TANI) containing materials was achieved by a one-step condensation reaction of mon…
A versatile and effective method by which a wide range of nanoparticulate materials can be attached to a variety of oxidic surfaces is presented. After synthesizing the nanocrystals (PbS, CdSe, CdSe@CdS core–shell, Au) via standard hot injection routes, the stabilizing ligands are exchanged to 3-mercatopropyl-trimetho…
(1-x) BaTiO 3 -x Bi ( Mg 1/2 Ti 1/2 ) O 3 (BT-BMT, 0.3 ≤ x ≤ 0.6) ceramics were prepared by the conventional mixed oxide method. Dielectric measurements showed highly diffusive and dispersive relaxor-like characteristics for all compositions. For 0.3 ≤ x ≤ 0.4, all these compositions possess a stable dielectric permit…
Phase field modeling has become a widely used framework in the computational material science community. Its ability to model different problems by defining appropriate phase field parameters and relating it to a free energy functional makes it highly versatile. Thermodynamically consistent partial differential equati…
With recent advances in nanotechnology, carbon nanotubes (CNTs) have been extensively studied as substrates for cell culture, drug delivery systems, and medical implant materials. However, surprisingly little is known about the effect of CNTs on collective cellular processes (e.g., adhesion, proliferation, and differe…
Directed self-assembly (DSA) of block copolymers (BCPs) is a promising technology for advanced patterning at future technology nodes. We use Self-Consistent Field Theory (SCFT) to model directed self-assembly (DSA) of PS-PMMA block copolymers on chemically patterned surfaces (chemoepitaxy). We consider the scenario in…
