The article demonstrates the crystalline silk nano-discs (CSNs), with well-controlled morphology, which upon magnetization, yields magnetic crystalline silk nano-discs, making both prominent alternatives for replacing metal templates such as gold, silver, and so on in therapeutics and implants. The isolated β-sheet-ri…
Starch films are developed as the biodegradable packaging materials to replace the petroleum-based materials in recent years. Thus, it is extremely beneficial to improve the hydrophobicity and mechanical strength of starch films, through a novel approach of co-cross-linking in neutral conditions, with glyoxal and AZC.…
Polysaccharides are attractive sustainable resources for the fabrication of advanced materials, but the assembly of these building blocks into complex-shaped structures combining the high strength and low weight required in many applications remains challenging. We have investigated and optimized the rheological and m…
The downward flow in a vertical duct with one heated and three thermally insulated walls is analyzed numerically using the two-dimensional approximation valid in the asymptotic limit of an imposed strong transverse magnetic field. The work is motivated by the design of liquid metal blankets with poloidal ducts for fut…
Abstract The present study involves bacterial cellulose (BC) production using freshly prepared apple juice medium (AJM) and the bacterial strain Gluconobacter xylinum CCM 3611T. The AJM was modified with ammonium sulfate, dipotassium phosphate, sucrose, acetic acid, with and without ethanol. BC sheets (in the dry stat…
Electrode material design is the key to the development of asymmetric supercapacitors with high electrochemical performances and stability. In this work, Al-doped NiO nanosheet arrays were synthesized using a facile hydrothermal method followed by a calcination process, and the synthesized arrays exhibited a superior…
The DSC, TG, DTA, and DTG analyses of boron silicides, which are widely applied in radiation material science and nuclear technology, have been performed depending on the thermal treatment rate. The kinetic parameters (energy, enthalpy, oxidation reaction rate, heat capacity, and activation energy) of effects occurrin…
BACKGROUND AND PURPOSE: Nanoparticle-loaded hydrogels - localized drug delivery devices containing a combination of therapeutic nanoparticles and implantable hydrogel - have been recipients of increased focus and interest for cancer treatment. However, it is difficult for the released nanoparticles to penetrate deeply…
Osseointegration is essential for ensuring optimal functioning and longevity of orthopedic implants. In a significant number of patients, the body does not fully integrate with the orthopedic implant, which opens the potential for the formation of bacterial biofilms and adverse foreign body reactions. Protein-function…
This research is a preliminary study on the preparation of wood plastic composites (WPC) from corn husk fiber (CHF) and recycled polystyrene foam (rPS). The effects of fiber content and alkaline treatment on tensile, thermal, water absorption and morphological properties of the composites were investigated. The rPS/CH…
Supported Pt catalyst has been intensively investigated for formaldehyde elimination owing to its superior reactivity at room temperature (RT). However, the high Pt content is challenging because of its high cost. Herein, we report PbO-supported Pt catalysts with only 0.1 wt % Pt, which can achieve complete conversion…
Hybrid catalysts composed of gold–palladium nanoalloys that are sandwiched between layers of graphene oxide (GO) and lamellar TiO 2 are synthesized via the deposition–reduction method. The resulting AuPd catalysts with different compositions of metal and support are fully characterized by a series of techniques, inclu…
The induction of limb repair in adult vertebrates is a pressing, unsolved problem. Here, we characterize the effects of an integrated device that delivers drugs to severed hindlimbs of adult Xenopus laevis, which normally regenerate cartilaginous spikes after amputation. A wearable bioreactor containing a silk protein…
Abstract In Belousov–Zhabotinsky (BZ) type reactions, chemical oxidation waves can be exploited to produce reaction-diffusion processors. This paper reports on a new method of encapsulating BZ solution in a powder coating of either polyethylene (PE) or polytetrafluoroethylene (PTFE), to produce BZ liquid marbles (LMs)…
The InTe has intrinsically low lattice thermal conductivity κL originating from the anharmonic bonding of In1+ ion in the lattice, which scatters the phonons. Here we report the enhancement of thermoelectric properties in Te-deficient InTe1−δ (δ = 0, 0.01, 0.1, and 0.2) polycrystalline compounds by lattice softening a…
Although number of stimuli-responsive drug delivery systems based on mesoporous silica nanoparticles (MSNs) have been developed, the simultaneous real-time monitoring of carrier in order to guarantee proper drug targeting still remains as a challenge. GQDs-MSNs nanocomposite nanoparticles composed of graphene quantum…
ABSTRACT Influences of different nanocomposite loadings in poly(lactic acid) (PLA) matrix on resulting hardness and elasticity were examined in nanoindentation experiments. The following study was focused on the nanomechanical properties of PLA reinforced with graphene nanoplatelets (GNPs) and multiwall carbon nanotub…
Mn-based intermetallic compounds have attracted much attention due to their fascinating structural and physical properties, especially their interesting hard magnetic properties. In this paper, we have summarized the magnetic and structural properties of Mn-based intermetallic compounds (Mn X , where X =Al, Bi, and Ga…
Gold nanoparticles (AuNPs) are widely used for drug delivery because of their unique biological properties, such as their safety and ability to prolong drug action. Some studies have demonstrated that AuNPs accumulate in the heart, especially during pathological processes. Therefore, it is very important to understand…
PANI and PANI-SiO2 were prepared by chemical oxidative polymerization in acidic medium of hydrochloric acid (1 M) using ammonium persulfate as oxidant. The developed adsorbents were characterized using various analytical techniques such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and phy…
