Abstract Low-cost, scalable, and abundant biomass-derived carbon materials have attracted considerable attention. Herein, we report on novel self-doped (nitrogen) porous carbon nanosheets by carbonization/activation of acorn shells as a biomass precursor for use in high-performance supercapacitors (SCs), which contain…

Stimuli-responsive materials are very attractive candidates for on-demand drug delivery applications. Precise control over therapeutic agents in a local area is particularly enticing to regulate the biological repair process and promote tissue regeneration. Macromolecular therapeutics are difficult to embed for delive…
Layered 1T-type TiS 2 powders were pretreated by an ethanol-based shear pulverization process, which showed outstanding effectiveness in reducing the average grain size and narrowing the size distribution while maintaining high crystallinity and plate-shaped morphology. The resulting bulk ceramics densified by spark p…
Methanolysis of sodium borohydride (NaBH4) is one of the methods efficient enough to release, on demand, the hydrogen stored in the hydride as well as in 4 equiv of methanol (CH3OH). It is generally reported that, in methanolysis, sodium tetramethoxyborate (NaB(OCH3)4) forms as single component of the spent fuel. It i…
Abstract Metal‐carbon nanotube (CNT) hybrid fibers are emerging materials for light‐weight conductors that can replace common metallic conductors. One of the main challenges to their development is the poor affinity between CNT and metals. In this work, a new approach for fabrication of CNT/Cu core‐shell fibers is dem…
Electrical contact is an essential issue for all devices. Although the contacts of the emergent two-dimensional materials have been extensively investigated, it is still challenging to produce excellent contacts. The face and edge type contacts have been applied previously, however a comparative study on the site-spec…
This work aims at investigating the free torsional vibration of one-directional nanostructures with an elliptical shape, under different boundary conditions. The equation of motion is derived from Hamilton’s principle, where Eringen’s nonlocal theory is applied to analyze the small-scale effects. The analytical Galerk…
Abstract Despite many advantages, poor mechanical properties are a limiting factor in market growth of natural fiber composites. This work is focused on improvement in the mechanical properties of hemp/green epoxy composites by using four different weave structures and by adding glass microspheres (GMS) to the resin.…
In western countries, one patient on twenty will develop a nosocomial infection during his hospitalization at health care facilities. Classical antibiotics being less and less effective, this phenomenon is expanding year after year. Prevention of bacteria colonization of implantable medical devices constitutes a major…
In this article, different standard and nonstandard continualization techniques are applied to a one-dimensional solid consisting in a chain of masses interacting with nearest and next-nearest neighbors through linear springs. The study focuses on the reliability of the different continua in capturing the dispersive b…
We conducted systemic assessments on the toxicity of silicon dioxide (SiO2) and titanium dioxide (TiO2) nanoparticles using different forms of normal colon cells (CCD-18Co), in vivo and in human colon organoids. The in vivo acute oral toxicity data showed that the LD50 values are greater than 2000 mg/kg for both the S…
Silk fibroin (Bombyx mori) was used to manufacture a nerve conduit (SilkBridge) characterized by a novel 3D architecture. The wall of the conduit consists of two electrospun layers (inner and outer) and one textile layer (middle), perfectly integrated at the structural and functional level. The manufacturing technolo…
One-dimensional nanostructure arrays hold great promise for orthogonalizing light absorption and carrier collection, and thus have been attractive building blocks for next-generation solar cells. Therefore, it is highly desired to build one-dimensional nanostructure arrays of novel photovoltaic materials. In this work…
Tb-substituted Ni0.4Cu0.2Zn0.4TbxFe2−xO4 (0.0 ≤ x ≤ 0.10) nanospinel ferrites were formed by sonochemical technique. It was first time established correlation between chemical composition of the nanosized NiCuZn spinels and their structural, electrical and microwave properties. The structure of nanospinel ferrites (NS…
Bacterial cellulose (BC), harvested from the hydrolysate of starch-rich solid in kitchen waste (KW), was employed to prepare a superhydrophobic stearic acid (SA)-modified BC aerogel (S-BCA) for cooking oil adsorption. S-BCA achieved some distinct differences in the porous structure, surface wettability, mechanical pro…
Herein, we report the novel strategy for the synthesis of complex 3-dimensional (3D) nanostructures, mimicking the linker molecule-free 3D arrangement of six Au nanospheres at the vertices of octahedrons. We utilized 3D PtAu skeleton for the structural rigidity and deposited Au around the PtAu skeleton in a site-selec…
Abstract The development of collagen hydrogels with tailored properties for improved applications in biomedicine represents an area of opportunity for materials science. The collagen can form semi‐interpenetrated networks (semi‐IPN) with various natural and/or synthetic polymers. This work aims the preparation of nove…
Chirality plays a key role in many fields ranging from life to natural sciences. For a long time, chiral materials have been developed and used to interact with chiral environments. In recent years, fluorescent carbon dots (CDots) are a new class of carbon nanomaterials exhibit excellent optical properties, good bioco…
Abstract The hardness of nanotwinned diamond (nt-diamond) is reported to be more than twice that of the natural diamond, thanks to the fine spaces between twin boundaries (TBs), which block dislocation propagation during deformation. In this work, we explore the effects of additional TBs in nt-diamond using molecular…
