Polymer blends have been obtained in the form of dimensionally stable and free standing films and their properties were characterized by different techniques. FTIR analysis and Raman spectroscopic analysis cleared the hydrogen bonding intermolecular interaction between –CONH2 groups in Poly Acrylamide (PAM) and C-O-C…
Contact angle methods are widely used to evaluate the wettability of cellulose-based surfaces and to judge their suitability for different applications. Wettability affects ink receptivity, coating, absorbency, adhesion, and frictional properties. There has been a continuing quest on the part of researchers to quantif…
Ultra-high temperature ceramics (UHTCs) are composed of ZrC, ZrB2, HfC, HfB2, HfN and TaC and their melting points are higher than 3000℃. They are a vital class of high temperature structural materials and have attracted a great deal of attention in the past two decades in fundamental research and in technological app…
High-resolution spectroscopic measurements using thermal and epithermal neutrons and first-principles calculations within the framework of density-functional theory are used to investigate the nuclear dynamics of light and heavy species in the metastable phase of caesium hydrogen sulfate. Within the generalised-gradie…
In this article, single-walled boron nitride nanotube (SWBNNT) vibration behavior is investigated based on nonlocal elasticity theory. The SWBNNT is analyzed as a nanobeam based on higher order shear deformation theory. Loading is composed of temperature change and axially external electric potential field. SWBNNT is…
The Dirac physics of silicene is preserved on the WSe 2 substrate with a sufficiently large band gap to withstand thermal fluctuations.
A novel approach to stimuli-responsive gel termed the "keto-enol tautomerization"-based response mechanism was proposed. By tautomerization, vinyl ketone-based gelator G3 can be self-assembled into an organogel (OG3) accompanied by strong AIE. OG3 shows reversible dual-channel response for S(2-). The response process…
A series of new triphenylamine functionalized β-diketones 1–3 and their difluoroboron complexes 1B–3B were synthesized. They exhibited strong intramolecular charge transfer (ICT) emission. It was found that their self-assembling properties depended on the molecular structures. For example, compounds 1 and 1B, in which…
We describe the design, synthesis, and fluorescent profile of two environment-sensitive dyes in which an electron-donating group is conjugated to an electron-accepting unit via a pyrrolo[3,2-b]pyrrole ring system. The maximum emission wavelength (λem) of these donor-donor-acceptor (D-D-A) pyrrolo[3,2-b]pyrroles was fo…
A dopamine functionalized, polyaspartamide-based polymeric nanoparticle has been synthesized for selective delivery of drugs to human colon adenocarcinoma cells.
The strong aggregation induced emission (AIE) and reversible mechanochromic behavior for tetraphenylethene (TPE) substituted pyrazabole 2 was reported.
Mn‐doped CeO 2 flower‐like microstructures have been synthesized by a facile method, involving the precipitation of metallic alkoxide precursor in a polyol process from the reaction of CeCl 3 ·7H 2 O with ethylene glycol in the presence of urea followed by calcination. By introducing manganese ions, the composition ca…
The tuning of charge carrier density of graphene is an essential factor to achieve the integration of high-efficiency electronic and optoelectronic devices. We demonstrate the reversible doping in graphene using deep ultraviolet (UV) irradiation and treatment with O2 and N2 gases. The Dirac point shift towards a posit…
Carbon nanofibers electrode.
Highly aligned manganese dioxide (MnO 2 ) nanowall arrays electrodeposited onto Ti sheets are used as substrates to grow graphene (GR) through chemical vapor deposition (CVD), thus forming a three-dimensional (3D) MnO 2 /GR hybrid composite.
Black tilapia (Oreochromis mossambicus) fish wastes (scales) were evaluated for its suitability as sources of gelatin. Scales were subjected to acid treatment for demineralization before it undergoes thermal extraction process. The raw scales were characterized via Scanning Electron Microscopy (SEM), which demarcated…
Chitosan is a biopolymer derived from chitin which is naturally occurring in the exoskeleton of crustaceans. This paper reports dissolution and regeneration of chitosan by directly dissolving in an ionic liquid solvent, 1-butyl-3-methylimidazolium chloride (BMIMCl). This will provide an ideal platform to solubilise th…
The conductivity measurements show that Mn doped EuFeO 3 compounds obey Jonscher's universal power law.
A cotton textile with robust composite film showed extraordinary superhydrophobicity, flame retardancy, durability and efficiency for water/organic solvent separation.
