We present in this study the physical properties of two deep eutectic solvent (DES) mixtures based on solid sulfonium bis[(trifluoromethyl)sulfonyl]imide (S 111 TFSI) aprotic ionic liquid and two different H-bond donors, formamide (FMD) and trifluoroamide (TFA), according to temperature. First, we investigated their t…
ABSTRACT Naphthalimide‐phthalimide derivatives (NDPDs) have been synthesized and combined with an iodonium salt, N‐vinylcarbazole, amine or 2,4,6‐tris(trichloromethyl)‐1,3,5‐triazine to produce reactive species (i.e., radicals and cations). These generated reactive species are capable of initiating the cationic polyme…
Directional attraction with lateral repulsion between colloidal nanoparticles can create their supracolloidal chains. Here, we demonstrate supracolloidal polymers of diblock copolymer micelles, which were polymerized by adjusting the polarity of the solvent. We also synthesized supracolloidal random and block copolyme…
The influence of hybrid reinforcements including silicon carbide and graphite particles with a size 37–50 μm on the wear characteristics of AZ91 magnesium alloy was studied. The dry sliding wear test was conducted using a pin-on-disc wear testing machine in the load range of 20 to 80 N at different sliding velocities…
Abstract BACKGROUND Cellulose as a renewable biomaterial has forced attention on the use of cellulose‐hydrolyzing enzymes for industrial bioconversion of lignocellulosic materials to glucose. This paper reports immobilization of cross‐linked cellulase aggregates (CLEA) on the amine‐functionalized Fe3O4@silica core‐she…
Novel silica nanofibrous membranes with ultra-softness of 40 mN and enhanced tensile strength of 5.5 MPa were prepared for the first time via an electrospinning process, which exhibited an ultra-low thermal conductivity of 0.0058 W m −1 K −1 .
The adsorption, electrokinetic, thermal and stability properties of the silicon dioxide (silica, SiO 2 )/bovine serum albumin (BSA) system were determined. All measurements were carried out as a function of solution pH value. The highest amount of BSA absorbed on the silica surface was observed at pH 4.6 [the value cl…
An aqueous spray-pyrolysis approach for synthesizing Cu(In,Ga)(S,Se) 2 thin film, which leads to 10.54% power conversion efficiency in solar cell, and shows ease of fabrication of films in large-scale at a much cheaper cost.
AIMS: Release of norepinephrine (NE) from sympathetic neurons enhances heart rate (HR) and developed force through activation of β-adrenergic receptors, and this sympathoexcitation is a key risk for the generation of cardiac arrhythmias. Studies of β-adrenergic modulation of cardiac function typically involve the admi…
Silicon can store Li(+) at a capacity 10 times that of graphite anodes. However, to harness this remarkable potential for electrical energy storage, one has to address the multifaceted challenge of volume change inherent to high capacity electrode materials. Here, we show that, solely by chemical tailoring of Si-carbo…
Three novel bis(amidate) rare-earth metal amides were prepared and characterized. Treatment of CO 2 with terminal alkynes obtained propiolic acids in high to excellent yields using the highest reactive Nd-based catalyst at ambient pressure.
This paper proposes a method for improving the reducing or oxidizing gas-sensing abilities of p-type oxide nanowires (NWs) by locally modifying the hole-accumulation channel through the attachment of p-type nanoparticles (NPs) with different upper valence band levels. In this study, the sensing behaviors of p-CuO NWs…
Widely used in catalysis and biosensing applications, aluminum oxide has become popular for surface functionalization with biological macromolecules, including lipid bilayer coatings. However, it is difficult to form supported lipid bilayers on aluminum oxide, and current methods require covalent surface modification,…
We present a silole ladder-type copolymer, PSiNO, with a high molecular weight that affords a remarkable PCE of 8.37%.
The review focuses on the effects of morphology, composition and interaction of 3d metal oxide–graphene composites on the performances of libs.
In this paper, a manganese phthalocyanine (MnPc) covalently functionalized graphene nanohybrid (MnPcG) has been successfully synthesized via 1,3-dipolar cycloaddition, and used as a photocatalyst after modifying it with platinum nanoparticles via photodeposition.
Magnetically separable CdFe 2 O 4 /graphene was synthesized as a visible light photocatalyst for the effective degradation of dyes and pollutants.
Mesoporous ZSM-5 zeolites with unique hydrocarbon cracking properties have been postsynthesized from conventional ZSM-5 samples using small molecular organic amine-assisted desilication technique.
Edge states are ubiquitous for many condensed matter systems with multicomponent wave functions. For example, edge states play a crucial role in transport in zigzag graphene nanoribbons. Here, we report microscopic calculations of quantum plasmonics in doped graphene nanodisks with zigzag edges. We express the nanodis…
Thiophene-flanked benzothiadiazole derivatives and their copolymers were synthesized via exclusive direct-arylation coupling reactions.
