The discovery of phenomena of volume phase transition has had a great impact not only on bulk gels but also on the world of microgels. In particular, research on poly(N-isopropylacrylamide) (PNIPAM) microgels, whose transition temperature is close to body temperature, has made remarkable progress in almost 35 years. T…
A new analysis proves that it is not possible for numerical algorithms to determine if a 1D quantum system has a spectral gap, showing that basic properties of even simple systems are, in some instances, impossible to predict.
Heterochain polymers such as DNA and proteins are abundant in nature, but they are not ubiquitous in man-made polymers due to the synthetic difficulties. Traditional polymerization methodologies including chain polymerization, step-growth polymerization, and coordination polymerization all show obvious drawbacks in sy…
A microcapsule is an ideal choice to realize effective utilization of a pesticide and reduce environmental pollution. A novel preparation method of a microcapsule was developed by complex coacervation of phosphonium ionic liquid (PIL) with gelatin. PIL was newly synthesized and used to dissolve and disperse avermectin…
Boiling histotripsy is a High Intensity Focused Ultrasound (HIFU) technique which uses a number of short pulses with high acoustic pressures at the HIFU focus to induce mechanical tissue fractionation. In boiling histotripsy, two different types of acoustic cavitation contribute towards mechanical tissue destruction:…
Using a one-step thermal reduction and non-covalent chemical functionalization process, PEGylated reduced nanographene oxide (rGOn-PEG) was produced from nanographene oxide (GOn) and characterized in terms of particle size, dispersion stability, chemistry, and photothermal properties, in view of its use for phototherm…
Semiconductor perovskite material has given important interest as a potential thermoelectric material (TE) due to its large thermopower (Seebeck coefficient, S). VScO3 Semiconductor Perovskite is investigated by the Density Functional Theory (DFT) using full potential linearized augmented plane wave (FP-LAPW) method w…
The low redox potential of conjugated donor–acceptor (D–A) type polymer due to strong electron interaction between donor units and acceptor units is benefit to increase the power density, which is suitable to serve as the anode materials of lithium-ion battery. In this paper, the D–A type polymers containing phenanthr…
Nonviral gene delivery has been considered as a powerful tool for cancer therapy because of its inherent advantages of nontoxicity, high specificity, and therapeutic efficacy. Successful cancer gene therapy mostly depends on the design of highly efficient and nontoxic vectors that can compress genetic materials and ef…
In this work, the effect of graphene oxide (GO) on the physical performance related properties of an asphalt binder was investigated in terms of penetration, softening point, viscosity (110–185°C), and ductility as well as temperature performance indices. Subsequently, response surface methodology (RSM) was used to ex…
Elastomer-based porous structures realized by selective laser sintering (SLS) are emerging as a new class of attractive multifunctional materials. Herein, a thermoplastic polyurethane (TPU) powder for SLS was modified by 1 wt.% multi-walled carbon nanotube (MWCNTs) or a mixture of MWCNTs and graphene (GE) nanoparticle…
Through the use of resonant two-photon ionization spectroscopy, sharp predissociation thresholds have been identified in the spectra of CrO, MoO, RuO, and RhO. Similar thresholds have previously been used to measure the bond dissociation energies (BDEs) of many molecules that have a high density of vibronic states at…
Recently, cell separation methods have become important for preparing cells for transplantation therapy. In this study, a thermoresponsive cationic block copolymer brush is developed as an effective cell separation tool. This brush is prepared on glass surfaces using two steps of activator regenerated by electron tran…
Fascicular rearrangement of an injured peripheral nerve requires reconnection of nerve sprouts from anterior and Büngner bands from distal sides of the lesion, failing to which leads to inefficient regeneration of the injured nerve. However, existing neural scaffolds have limited neuroregeneration efficiency because o…
Oral delivery of biologic drugs is a highly desired yet challenging goal because of the many barriers posed by the GI tract. Ionic liquids (ILs) and deep eutectic solvents (DESs) such as choline and geranate (CAGE) have demonstrated the potential to improve intestinal absorption of insulin and poorly soluble drugs. As…
Graphene, known as “black gold”, has important applications in various fields. In previous studies, it has been proved that graphene oxide (GO) which is a derivative of graphene has low toxicity. However, the immunotoxicity of GO has not been fully elucidated. In this work, we used DC2.4 cell line to investigate the i…
Oxygen-vacancy-ordered brownmillerite oxides offer a reversible topotactic phase transition by significantly varying the oxygen stoichiometry of the material without losing its lattice framework. This phase transition leads to substantial changes in the physical and chemical properties of brownmillerite oxides, includ…
Wound care and soft tissue repair have been a major human concern for millennia. Despite considerable advancements in standards of living and medical abilities, difficult-to-heal wounds remain a major burden for patients, clinicians and the healthcare system alike. Due to an aging population, the rise in chronic disea…
Ectoine and its derivative 5-hydroxyectoine are compatible solutes and chemical chaperones widely synthesized by Bacteria and some Archaea as cytoprotectants during osmotic stress and high- or low-growth temperature extremes. The function-preserving attributes of ectoines led to numerous biotechnological and biomedica…
Organic optoelectronic molecules with resonance effects are a striking class of functional materials that have witnessed booming progress in recent years. Various resonances induced by particularly constructed molecular structures can effectively influence key photophysical processes to afford particular optoelectroni…
