The growing consumption of tender coconut water in Brazil has resulted in a generation of green husk, which in turn has led to pollution, as it takes eight to ten years to degrade. With the objective of finding applications for these fibers, the characterization of their chemical composition, tensile properties, and s…
The authors discuss a fast memory application based on thermal hysteresis in a magnetically driven superconducting quantum interference device (SQUID). Their theoretical exploration of the coherent thermal transport in an inductive temperature-biased SQUID reveals appreciable bistability of electrode temperature in th…
The electronic properties of titanium(IV) sulfide (TiS 2 ) have been scrutinized for many decades due to its strong tendency toward nonstoichiometry with either titanium excess or sulfur deficiency in its crystal structure. Here, the systematic solid-state transformation of TiS 3 to TiS 2– x nanobelts as a means to co…
The inherent properties of a single atomic carbon layer in graphene offer opportunities for the creation of catalytically active centers tailored on a molecular level on a support with high thermal stability and very high specific surface area. We demonstrate that organization of the two-dimensional system of the carb…
A novel design of spoof surface plasmon polariton (SSPP) planar antenna is proposed based on the wave vector modulation of transmissive phase gradient metasurface (TPGM). The antenna consists of TPGM placed a certain distance above SSPP guided wave structure, exhibiting the directional radiation property according to…
ABSTRACT This study evaluated the thermal, morphological, chemical, and mechanical properties of virgin and recycled polystyrene. The recycling process was carried out by dissolution of polystyrene (extruded and crystal) in ethyl acetate, followed by two processes for solvent removal: vaporization by direct contact wi…
This chapter looks at variables such as fibril diameter, orientation, tissue distribution, relative concentrations and packing of fibrils into larger volumes, and search for patterns which occur during development and aging. It presents an overview of the molecular structure and functions of collagen, its biosynthesis…
New strategies for synthesis of Janus particles are of essential importance in the advancement of material science and technology. However, it remains a great challenge to synthesize uniform Janus particles with controllable topological and chemical anisotropy. To overcome this challenge, we have recently developed a…
Abstract Chromophore reactions with changes to conjugation degree, especially those between the conjugated and unconjugated state, will bring a large spectral variation. To realize such a process, a meso-naked BODIPY (MNBOD) with two electron-withdrawing groups around the core is designed and synthesized. The resultin…
Abstract The family of subphthalocyanine (SubPc) macrocycles represents an interesting class of nonplanar aromatic dyes with promising features for energy conversion and optoelectronics. The use of SubPcs in biomedical research is, on the contrary, clearly underexplored, despite their documented high fluorescence and…
Abstract Quantum beats, periodic oscillations arising from coherent superposition states, have enabled exploration of novel coherent phenomena. Originating from strong Coulomb interactions and reduced dielectric screening, two-dimensional transition metal dichalcogenides exhibit strongly bound excitons either in a sin…
Self-assembly processes allow designing and creating complex nanostructures using molecules as building blocks and surfaces as scaffolds. This autonomous driven construction is possible due to a complex thermodynamic balance of molecule-surface interactions. As such, nanoscale guidance and control over this process is…
The additives AlCl3, CoCl2, Al(OH)3, Ca(OH)2, and NaAlO2 are added to water to regulate its pH value (pH = 2-13) in this study. The effects of media on the aluminum-water reaction are investigated. Up to an increase in temperature, the hydrogen generation rate in different media increases. H+, OH−, Cl−, or Co produced…
Limonene dimercaptan (LDM), an orange peel oil‐based derivative, and glycerol‐1‐allyl ether (GAE) were used to synthesize bio‐based polyol (LDM‐GAE) using one step photochemical thiol‐ene reaction. The synthesized polyol was used to prepare flame retardant polyurethane foams using dimethyl methyl phosphonate (DMMP) as…
CuFe2O4 nanoparticles (CNPs) with cubic and tetragonal spinel structures were synthesized by Jatropha oil-assisted green combustion route (GCR) and urea-assisted chemical combustion route (CCR) and well-characterized. The photocatalytic activity of CNPs prepared via GCR and CCR showed 96 and 83% sunlight degradation o…
Abstract In recent years, various van der Waals (vdW) materials have been used in implementing high‐performance photodetectors with high photoresponsivity over a wide detection range. However, in most studies reported so far, photodetection in the infrared (IR) region has not been achieved successfully. Although sever…

The carbon fiber cloth was treated by surface treatment, and then it was used as the electrode substrate. The electrode material based on carbon fibers was synthesized by a galvanostatic electrodeposition method. The interface resistivity, electrochemical property and corrosion resistance of the CF/β-PbO2 electrode we…
Fe-doped V6O13 was synthesized via a facile hydrothermal method after preparing precursor in order to improve the discharge capacity and cycle performance of V6O13 cathode material at high-lithium state. XRD, SEM and XPS were employed to characterize the phase, morphology and valence of the Fe-doped V6O13. Meanwhile,…
