Natural biopolymer materials have enormous potential in important, rapidly growing applications ranging from green electronics, dye and heavy metal removal, oil/water separation, therapeutic agent delivery, tissue engineering scaffolds, biological devices, optics, and sensing. However, the application of advanced func…
Colloidal monolayers are important tools to fabricate surface structures at the nanoscale. A typical monolayer fabrication strategy involves the self-assembly of colloidal building blocks at liquid interfaces, which are subsequently deposited on a solid substrate. Even though this process is well established, the resu…
Cu2Te is a superionic conductor that belongs to the Phonon Liquid Electron Crystal class of thermoelectric (TE) materials. Despite the simple chemical formula, the crystal structures and phases in the Cu2Te system have not been understood properly. In this work, we study the structural and TE properties of Cu2Te (CT2)…
Efficient strategies to prepare carbon materials with improved electrochemical performance for supercapacitors have been in great demand. Herein, we develop multiple-heteroatom-doped carbons (from single- to triple-doped) by pyrolysis of polyimide precursors using a facile in situ approach. This approach can be used t…
Although protonic ceramic fuel cells (PCFCs) have a great potential to realize higher energy-conversion efficiency compared with all other conventional devices, actual PCFCs have shown current leakage loss due to their intrinsic transport property with electron-hole conduction of proton-conducting electrolytes, result…
This study provides a novel value‐added utilization of the agroindustrial waste of royal palm tree leaf sheath to produce cellulose acetate. One of the motivations of this work was the fact that Brazil is one of the largest heart of palm producers in the world. However, as a result of extraction and processing, tons o…
Abstract 0.75(Na 0.5 Bi 0.5 )TiO 3 –0.25SrTiO 3 lead‐free incipient piezoceramic is a promising candidate for actuator applications due to their large reversible electromechanical strains at the relatively low driving field of 40 kV/cm. In order to further reduce the driving field of 0.75(Na 0.5 Bi 0.5 )TiO–0.25SrTiO…
Understanding the mechanical stability of granular-armored liquid marbles is prerequisite for their applications including encapsulation, sensors, microreactions, and miniaturized liquid storage. Most liquid marbles are armored with agglomerated granular structure which complicates the wetting and interacting states o…
This century is struggling with the issue of environment friendly management of the pollutants which are contaminating the environment. One of an ecofriendly and economically feasible method is the bioremediation of pollutants using bio nanoparticles. Nanobioremediation is a highly studied and explored area of remedia…
Crystallization has been applied to a broad range of industries such as bulk and fine chemicals and the pharmaceutical and food industries. It is important to strategically control the in situ purification process during crystallization to meet the regulatory and functional specifications of the crystals. While the co…
VO 2 has been intensively studied as a model system for metal‐insulator transition (MIT), ever since its phase switching behavior at relatively low temperature ( T c = 68 °C) was discovered. Its thermo‐active characteristics have been studied for applications in thermal solar collectors to prevent overheating of the f…
Cell behavior is dependent in part on chemical and physical cues from the extracellular matrix. Although the influence of various cues on cell behavior has been studied, challenges remain to incorporate multiple cues to matrix systems to optimize and control cell outcomes. Here, aligned silk fibroin (SF)-graphene hydr…
The living anionic copolymerization of isoprene and styrene in cyclohexane affords tapered block copolymers due to the highly disparate reactivity ratios of r I = 12.8 and r S = 0.051. Repeated addition of a mixture of these monomers was exploited to generate tapered multiblock copolymer architectures of the (AB) n ty…
The work at hand focuses on an adaptive system aimed at improving the soundproof performance of car door seals at specific regimes (cruise), without interfering with the conventional opening and closing operations. The idea addresses the necessity of increasing seal effectiveness, jeopardized by aerodynamic actions th…
This paper reports a rapid (5 min), low temperature (120 °C) method to platinize the counter electrodes of dye-sensitized solar cell (DSC) devices. This new method uses aqueous solutions and is based on chemical bath deposition of an activating Pd layer followed by Pt only using H2 gas as the reductant. This method ha…
Hybrid stereocomplex bionanofibers were fabricated with high piezoresponse, multicolor luminescence and improved heat-resistance.
We report on the design of abundant and highly active VB 2 for hydrogen production. Density functional theory (DFT) calculations have predicted very high HER activity of the graphene-like B-layer, the V-terminated {100} layer, and the mixed V/B-terminated {101} layer of VB 2 . Bulk samples and nanoparticles of VB 2 we…
Bismuth telluride (Bi 2 Te 3 ) based alloys are preferred thermoelectric materials for room temperature thermoelectric applications. Electrical transport and thermopower properties of n-type nanostructured Bi x Sb 2-x Te 3 films were tuned by post-growth heat treatment. We report that annealing of sputter-deposited na…
In the present study, we have developed a green approach for the synthesis of silver nanoparticles (DSAgNPs) using aqueous extract of Durio zibethinus seed and determined its antibacterial, photocatalytic and cytotoxic effects. Surface plasmon resonance confirmed the formation of DSAgNPs with a maximum absorbance (λma…
Diamane, a chemically derived two-dimensional material, shows many superior physical and chemical properties similar to diamond thin films. Through the Peierls-Boltzmann transport equation, we reveal giant thermal conductivity in diamane with a stacking order of both AB and AA (respectively, abbreviated as D-AB and D-…
