Peukert's equation is widely used to model the rate dependence of battery capacity, and has recently attracted attention for application to supercapacitors. Here we present a newly developed method to readily determine Peukert's constant using impedance spectroscopy. Impedance spectroscopy is ideal for this purpose as…
Abstract Hierarchical nanoporous carbon (NPC) with great surface area and developed pore size distribution has been intently concerned. Herein, we report a facile method coupling template nanocasting and self-activation to fabricate nanoporous carbon with continuous micro, meso and macro pores, in which CaCO 3 acted a…
Due to the global demand for fibrous light-weight materials, research on composites reinforced with plant materials has increased. Natural fiber reinforced composites offer several advantages: light weight, competitive specific mechanical properties, easy processing, large volume availability, low cost, and low enviro…
ABSTRACT A series of side‐chain liquid‐crystalline polymers (SCLCPs) containing triphenylene mesogen, in which the long alkyl tail Tp connected directly with main chain, were synthesized successfully. The chemical structures of the monomers were confirmed by 1 H NMR and mass spectrometry. The phase behaviors of polyme…
Natural source-based composites became promising substitutes and synthetic petrochemical-based counterparts. So far, thermoplastic starch and lignocellulosic fibers are the most common materials for making such eco-friendly ?green? materials. Low cost, abundance, and renewability are the factors that lead to deploying…
Poly(vinyl ketone)s bearing push–pull triphenyamine moiety indicated remarkable absorption hypochromism, reduced redox potentials, and emission red shifts due to a π-stacked conformation.
An evaporative pre-concentration method towards environmental monitoring for sustainability working in an energy conserving manner.
Reported are the syntheses, structures and magnetic properties, also by NMR spectroscopy in solution, of a series of 13 linear trinuclear 3d–4f compounds with a lanthanide( <sc>iii</sc> ) surrounded by two Ni <sup>II</sup> ions, NiII2Ln <sup>III</sup> , where the central Ln <sup>III</sup> is hexacoordinate.
In this chapter, a review is made on the processing and properties of hybrid composites based on a polymer matrix and a blend of different natural (lignocellulosic) fibers. In particular, the processing methods are described and comparisons are made between the general properties with a focus on physical, mechanical a…
Cellulose has a complicated supramolecular structure consisting of nanofibrils, which are built of ordered crystallites and low ordered noncrystalline domains.In this critical review, isophase temperature transitions in noncrystalline domains of cellulose were described and discussed.It has been shown that due to stru…
Nascent ultrahigh molecular weight polyethylene (UHMWPE) is a thermoplastic material, consisting of nodular-fibrillar structure making it too much porous. At the present work, the effect of both particle morphology and chain entanglements on the sintering of UHMWPE was investigated. Neck growth for particles of three…
Molecular dynamics simulations are used to provide strong evidence for barrier-free nucleation events in a heterogeneous solid-solid system. The barrier-free events are characterized by an absence of an incubation time and a growth rate of the emerging phase that is independent of the system size. Furthermore, an anal…
Abstract Nitrates have long been ignored for practical uses as nonlinear optical (NLO) materials because they are usually very easy to dissolve in water; despite this, the π‐conjugated [NO 3 ] − is among the most desirable NLO‐active structural units. The cooperation of three structural chromophores, namely, Bi 3 O 6…
In this work, experimental solubility data of para-tert- butylbenzoic acid in binary solvents of acetic acid + water (293.15 to 333.15) K, methanol + water (293.15 to 328.15) K, and acetic acid + para-tert -butyltoluene (293.15 to 323.15) K were studied over acetic acid/methanol mass fraction, w 2 (on solute free basi…
Perylene diimide derivatives were used as probes to investigate the effect of the molecular structures on the fluorescence quenching mechanism in a perylene diimide/graphene oxide system. The electrons transferred from the excited state of dyes to the conductive band of graphene oxide with different concentrations wer…
Recently, with increasing environmental awareness and expanding global waste problems, eco-friendly biofillers have been recognized as a promising alternative to inorganic fillers in the reinforcement of thermoplastic and biodegradable plastics. Therefore, many industries are seeking more eco-friendly materials that w…
Infrared response on a carbon nanotube is weak because this homonuclear allotrope of carbon does not bear permanent dipoles. Here, we report the discovery of an exaltation of the infrared absorption response in single-walled carbon nanotubes from dye molecule interactions. A study performed on dimethylquaterthiophene…
Oligonucleotide-coated nanoparticles (NPs) have been used in numerous applications such as bioassays, as intracellular probes, and for drug delivery. One challenge that is confronted in the preparation of oligonucleotide-NP conjugates is derived from surface charge because nanoparticles are often stabilized and made w…
Tyranno SA (SiC-polycrystalline fiber, Ube Industries Ltd.) shows excellent heat-resistance up to 2000 o C with relatively high mechanical strength. This fiber is produced by the conversion process from a raw material (amorphous Si-Al-C-O fiber) into SiCpolycrystalline fiber at very high temperatures over 1500 o C in…
The interaction of Sepia officinalis cuttlefish bone, made of aragonitic CaCO3, with (NH4)2HPO4 boiling solutions produces porous carbonate-bearing hydroxyapatite (Ca10(PO4)6(OH)2) scaffolds with extremely large specific surface area. Percentages of aragonite into hydroxyapatite conversion close to 90% are reached aft…
