Multistimuli-responsive camouflaging and autonomously propelled swimmers are presented. These bioinspired artificial swimmers are capable of color changing in response to a variety of environmental stimuli such as temperature, pH, and light. By multiplexing different stimuli-responsive materials on a single swimmer, a vast library of independently addressable colors can be achieved. Unlike other color-changing robots, our color-changing swimmers can move autonomously in solution and are decoupled from tethered supports. The utilized leuco dyes, pH indicators, and phosphorescent powders display excellent reversibility and prolonged color retention. Finally, we design camouflage patterns which render the swimmers invisible against virtually any background, while revealing the swimmer upon changing the environmental conditions. By mimicking animal camouflage strategies these artificial swimmers present a significant step toward realizing multienvironmental stimuli-responsive color-changing strategies for the next generation of smart robotics. Such capabilities can be further enhanced by coupling color-changing ability with stimuli-triggered speed or shape change.

This paper presents the prediction of remaining service life of the land concrete as distinguished from the marine concrete. This study assumes that the land concrete is deteriorated by following three cases: carbonation, using sea sand and using deicing salts. In case of carbonation deterioration, statistical analysis and the depth of carbonation front are considered. This depth is assessed about 3.6-8.3 mm and can give more exact prediction than just carbonation depth by phenolphthalein. In case of using sea sand, various specimens considering chloride contents, carbonation accelerating, cover depth, relative humidity and water cement ratio are measured by linear polarization resistance method and half-cell potential method during the 1 year. And measurements of the real steel loss give the conversion ratio of polarization resistance and corrosion rate; consequently, their results make the prediction equation of rust growth during any specified period. In case of using deicing salts, surface chloride contents that change with time are focused. The proposed methods are considered to be useful for prediction of remaining service life of the land concrete by steel corrosion.

The traditional manufacturing process of 1,3-dioxolane requires high investment and energy consumption. A reactive distillation with pressure-swing distillation process is proposed as an attractive candidate based on the process simulation results in this work. To simulate the reactive distillation process, the kinetics experiments of formaldehyde aldolization with ethylene glycol were performed over NKC-9 cationic-exchange resin catalyst at 353-368 K. Byproducts were observed, and the batch distillation experiment were carried out to determine the boiling point temperatures ranking. A calculation strategy of aqueous and ethanediolic formaldehyde solutions was developed to solve the vapor-liquid equilibrium. The sensitivity analysis result shows that the yield of 1,3-dioxolane could be improved to 0.995 in the reactive distillation column, and high-purity 1,3-dioxolane (99.9 wt %) can be obtained in the following pressure-swing distillation process. The research achievements provides a new 1,3-dioxolane production process, which has an advantage in equipment integration.

The current work describes the investigation of film and gel samples, which combine poly (vinyl alcohol) (PVA) and gelatin containing thymolphthalein dye (TP). Under the effect of gamma radiation, two different media prepared as a label film and gel dosimeter its color changed from blue to colorless. Results demonstrated that the new detector systems for application in the low and high dose ranges were from 1 to 6.5 kGy in case of film and from 0.5 to 100 Gy as gel. The response of these dosimeters shows excellent post-irradiation stability at different storage time. These dosimeters are independent of the relative humidity at the time of irradiation in the range of relative humidity from 0 to 60%. Uncertainty of this radiation dosimeter was calculated as well as a comparison between two radiation dosimetry systems and suggest their possible application for both low and high dose dosimetry applications in medicine and industry.

Three component thermochromic dyes including fluoran type leuco dye, n-tetradecanol, and phenolphthaleinwere prepared and encapsulated in polymethylmethacrylate in this study. Nanoencapsulated system was prepared via oil in water emulsion polymerization technique. According to the morphological investigation by SEM, nanocapsules having spherical shape, compact morphology and lower average diameter around 200 nm were prepared successfully. UV?Visible Spectroscopy analysis and the photographs taken by a digital camera indicated that thermochromic systems and their nanocapsules exhibited reversible color change with thermal stimuli. They were green color at room temperature and lost their color at temperatures upon melting point of the thermochromic systems. In the study, 2,4-dihydroxybenzophenone and 2-hydroxy-4-methoxybenzophenone were added to the thermochromic systems to investigate UV resistance of the colorants in the systems. The effect of the UV absorbers on UV resistance of the thermochromic systems was investigated by color measurements based on CIELab system after UV aging of the nanoencapsulated systems. The results proved that especially 2,4-dihydroxybenzophenone was an effective material for increasing UV resistance of the systems and had color developer property. Besides, both thermochromic systems and their nanoencapsulated derivatives exhibited thermal energy storage/releasing property. While thermochromic systems had a heat storage capacity of over 200 J/g, the heat storage capacity of their nanocapsulated derivatives had reached up to 180 J/g. Melting temperature of the solvent n-tetradecanol decreased slightly in the thermochromic systems and further in nanoencapsulated form due to the cryoscopic effect of the non-volatile solutes in the system.

DISAPPEARING inks are used in textile industry such as dressmaking crafts and as a kind of teaching material; for example, printed questions are visible and the spaces for an answer exhibit invisible disappearing ink. The answers only become visible using a coloring assistant. This research was conducted on the preparation of disappearing inks using different concentrations of thymolphthalein (Th-ph) and O-Cresolphthalein (O-Cph). The prepared inks were applied to different types of handwriting papers. It was found that the handwriting stability increased by increasing thymolphthalein (Th-ph) and O-Cresolphthalein (O-Cph), or alkali concentration. Deciphering of the faded documents was evaluated by different methods. Commercial paper C2 surfaces gave the more handwriting stability than other paper, the order of stability were C2 ? C1 > Azhar >Xerox > C3 > C4 > Edfo. All the faded documents were visible when treated with alkaline solution. When the faded documents surfaces are exposed to the thermal effect there is no change in all the faded documents. Disappearing inks have been used in different fields, but it may be abused in forgery and counterfeiting.

Adaptive antibiotic resistance is a newly described phenomenon by which Acinetobacter baumannii induces efflux pump activity in response to host-associated environmental cues that may, in part, account for antibiotic treatment failures against clinically defined susceptible strains. To that end, during adaptation to growth in human serum, the organism induces approximately 22 putative efflux-associated genes and displays efflux-mediated minocycline tolerance at antibiotic concentrations corresponding to patient serum levels. Here, we show that in addition to minocycline, growth in human serum elicits A. baumannii efflux-mediated tolerance to the antibiotics ciprofloxacin, meropenem, tetracycline, and tigecycline. Moreover, using a whole-cell highthroughput screen and secondary assays, we identified novel serum-associated antibiotic efflux inhibitors that potentiated the activities of antibiotics toward serum-grown A. baumannii. Two compounds, Acinetobacter baumannii efflux pump inhibitor 1 (ABEPI1) [(E)-4-((4-chlorobenzylidene)amino)benezenesulfonamide] and ABEPI2 [N-tert-butyl-2-(1-tert-butyltetrazol-5-yl) sulfanylacetamide], were shown to lead to minocycline accumulation within A. baumannii during serum growth and inhibit the efflux potential of the organism. While both compounds also inhibited the antibiotic efflux properties of the bacterial pathogen Pseudomonas aeruginosa, they did not display significant cytotoxicity toward human cells or mammalian Ca2+ channel inhibitory effects, suggesting that ABEPI1 and ABEPI2 represent promising structural scaffolds for the development of new classes of bacterial antibiotic efflux pump inhibitors that can be used to potentiate the activities of current and future antibiotics for the therapeutic intervention of Gram-negative bacterial infections.

An enzyme-free titer plate-based colorimetric assay utilizing functionalized mesoporous silica nanoparticles (MSNs) entrapping pH-indicator molecules has been developed. Pores in the silica nanoparticles were functionalized with phenyltrimethyloxysilane so that pH indicator molecules (thymolphthalein or TP in the present case) can be tightly entrapped through pi-pi conjugation. To detect prostate specific antigen (PSA), the TP-containing MSNs were coated with polyethylenimine (PEI), which favors the attachment of the negatively charged secondary anti-PSA antibody. The entrapped thymolphthalein molecules can be readily released from the pores with a simple addition of alkaline solution. The resultant bifunctional MSNs were used for signal-amplified detection of PSA captured by the primary antibody preimmobilized in the wells of a plate. Our method possesses a wide dynamic range (0.5 to 8000 pg/mL) wherein the adsorption of the bifunctional MSNs obeys a modified Langmuir isotherm. A detection limit (LOD) down to as low as 0.36 pg/mL can be attained. Owing to the size uniformity of the MSNs and the obviation of enzyme molecules employed in the enzyme-linked immunosorbent assay (ELISA), excellent reproducibility (RSD = 1.12%) was achieved. The selective detection of PSA in human serum samples demonstrates the amenability of our method to detect important biomarkers in complex biological samples, whereas the performance of the assay in a titer plate ensures high throughput and obviates the use of expensive instruments. Both of these features are prerequisites for clinical settings wherein a great number of samples need to be analyzed in a timely fashion.

Mixtures of benzoic acid with various organic compounds are subjected to plastic deformation in Bridgman anvils under a pressure of 1 GPa at room temperature. The influence of high-pressure plastic deformation on the calorimetric behavior of the deformed layer of benzoic acid in mixtures with various organic components is studied under conditions of thermal treatment (programmed heating at a constant rate). The parameters for the process of melting of deformed layers of benzoic acid mixtures depending on the chemical composition are studied by differential scanning calorimetry (DSC). In all cases, the melting point Tm decreased by 5?8 deg. The melting enthalpy both can increase by 1.7 times and decrease by 2.3 times. In mixtures with organic indicators, the melting enthalpy of the acid depends on the pH of the indicator and reaches 750 J g?1 in a mixture with Congo red.
