Nanozymes, the enzyme-mimicking nanomaterials, have been developed to overcome the low stability and high cost of natural enzymes. Unlike highly active and specific enzymes, however, the catalytic activities of nanozymes are moderate and lack specificity. To address these issues, herein we demonstrated an effective an…
2D semiconductors such as transition metal dichalcogenides (TMDs) and black phosphorus (BP) are currently attracting great attention due to their intrinsic bandgaps and strong excitonic emissions, making them potential candidates for novel optoelectronic applications. Optoelectronic devices fabricated from 2D semicond…
The ever-growing world population results in the ineluctable increase of food demand which translates in the augment of the global market of packaging materials. Hence, the concept of active packaging materializes as a technology to enhance the safety, quality and shelf-life of the packaged foods. Active packaging sys…
Several scientific areas have benefited significantly from the introduction of nanotechnology and the respective evolution. This is especially noteworthy in the development of new drug substances and products. This review focuses on the introduction of nanomedicines in the pharmaceutical market, and all the controvers…
Collagen is the oldest and most abundant extracellular matrix protein that has found many applications in food, cosmetic, pharmaceutical, and biomedical industries. First, an overview of the family of collagens and their respective structures, conformation, and biosynthesis is provided. The advances and shortfalls of…
Linear porphyrin oligomers have found various applications as synthetic molecular wires in the context of light harvesting, solar energy conversion and molecular electronics. In many of these applications a partial ordering of the molecules helps to improve the reaction efficiency or device performance. In this work w…
Chemical vapor deposition (CVD) is known to produce continuous, large-area graphene sheet with decent physical properties. In the CVD process, catalytic metal substrates are typically used as the growth template, and copper has been adopted as the representative material platform due to its low carbon solubility and r…
Abstract The search for a global minimum related to molecular electronic structure and chemical bonding has received wide attention based on some theoretical calculations at various levels of theory. Particle swarm optimization (PSO) algorithm and modified PSO have been used to predict the energetically stable/metasta…
Abstract We have studied the electron–phonon interaction (EPI) in multiferroic PrFe 3 (BO 3 ) 4 applying reflection methods in far-infrared (terahertz) spectral range and theoretical simulations. A specific feature of PrFe 3 (BO 3 ) 4 is that the 4f-electron excitation of the Pr 3+ ion falls into a range between the l…
Surface pressure-area isotherms were recorded under different irradiation conditions for single-component Langmuir films of three photochromic amphiphilic dithienylethenes. Nonirradiated films of these photochromic amphiphiles were mechanically stable. In addition, a shift of the isotherms to larger mean molecular are…
Poor moisture resistance of natural fiber reinforced bio-composites is a major concern in structural applications. Many efforts have been devoted to alleviate degradation of bio-composites caused by moisture absorption. Among them, fiber pre-treatment has been proven to be effective. This paper proposes an alternative…
In different hydrocarbons reactions, copper based catalysts have industrial importance especially in the synthesis of the cyclohexanone from dehydrogenation of the cyclohexanol. At operating conditions, one of the significant problems in the industrial process is fast deactivation of the copper based catalysts. The pr…
Abstract The blood–brain barrier (BBB) can block drug delivery into the human brain, and thus remains the primary obstacle in the efficient treatment of glioma. Herein, Polyporus Amboinensis Lam (PAL)‐functionalized selenium nanoparticles (SeNPs) (hereafter referred to as PAL‐SeNPs) are fabricated as a cancer‐targeted…
Abstract Silver nanoparticles (AgNPs) have become known as a broad‐spectrum antimicrobial agent. The antimicrobial activity of AgNPs is dependent on the particle size and the dispersion status. In this study, a simple and effective approach is developed for sequestering the biosynthesized AgNPs in silica composites du…
New polyurethanes were synthesized based on dihydroxy fatty acid obtained by the microbial conversion of olive oil. Monounsaturated 7,10-dihydroxy-8(E)-octadecenoic acid (DOD) was produced from olive oil by Pseudomonas aeruginosa PR3 and reacted with hexamethylene diisocyanate (HMDI) at different ratios to form polyur…
With the development of fiber optic sensing technology, optical fiber sensors have been widely used in online monitoring of power transformers. To investigate the influence of aging fiber sheaths on transformer oil, two kinds of special optical fibers with thermoplastic polyester elastomer (TPEE) and poly tetra fluoro…
Abstract The wide applications of silver nanoparticles (AgNPs) have raised many concerns worldwide regarding their safety. The few previous studies on the developmental toxicity of AgNPs have been mostly dependent on animal experiments, which are time‐consuming and costly. The rapid development of stem cell biology pr…
In this work the adsorption capacities of methylene blue on Mg-smectite and sepiolite and its derived material obtained after acid treatment and/or the addition of Fe at its surfaces are studied. Natural smectite with high Mg-content in its octahedral sheet (Mg-smectite) displays higher adsorption capacity than the se…
Purpose To investigate the dependence of magnetization transfer ratio asymmetry at 3.5 ppm (MTR asym (3.5 ppm)), quantitative amide proton transfer (APT # ), and nuclear Overhauser enhancement (NOE # ) signals or contrasts on experimental imaging parameters. Methods Modified Bloch equation‐based simulations using 2‐po…
Single-phase materials with room temperature (RT) exchange bias (EB) are very important for future applications in spintronic devices, magnetic storage, and sensors. However, such materials are rare because EB normally occurs with ferromagnetic (FM)/antiferromagnetic (AFM) boundaries. In this work, RT EB was realized…
