A cobalt-free humidity indicator (HDI) for silica gel was developed using tetraphenylporphyrin (Tpp), which showed a distinguishable color change depending on pH. The HDI was prepared by mixing dichloro (tetraphenylporphyrinato)- phosphorus chloride (PTpp) and MgCl2 with SiO2 and drying at 130°C for 24 h. During the preparation, the PTpp was decomposed into the protonated Tpp (H2Tpp2+). The pH change arose from proton release by the reaction of MgCl2 with silanol of the SiO2 under dry conditions and neutralization under humid conditions. The HDI showed green color due to H2Tpp2+ under dry conditions and orange color due to Tpp under humid conditions. However, the HDI underwent partial decoloration on extended exposure to sunlight. Here, to prevent this decoloration, UV-absorbents coumarin and dibenzosuberenone were loaded onto the HDI. The HDIs with coumarin and without coumarin were irradiated at 352 nm and their microscopic absorption spectra were measured on a confocal laser scanning microscope. The absorbance at 650 nm and 515 nm of the HDI were monitored under dry and wet conditions, respectively. The light-protecting ability of UV-absorbent was analyzed by assuming that the decomposition process obeyed first-order kinetics. It was concluded that the additions of 0.125 wt% of coumarin and 0.050 wt% of dibenzosuberenone were effective to prevent decoloration of green color of H2Tpp2+ as well as orange color of Tpp. © 2017 The Society of Chemical Engineers, Japan.

Aldehyde oxidase (AOX)-immobilized silica gel (AOX-SG) was developed as a means to remove formaldehyde in the gas phase by enzyme degradation. AOX from the formaldehyde-tolerant microorganism Paecillomyces variotii IRI017, which we newly isolated from soil, was utilized. Amino group-binding silica gel (AminoSG) was prepared by APTE (3-aminopropyl triethoxysilane) treatment. All types of AOX-immobilized silica gels were oven-dried at 50°C to constant weight, and formaldehyde degradation by the dried AOX-SG or AOX-aminoSG was examined. Humidified air containing 0.4–0.5 ppm of formaldehyde was passed continuously through SG columns packed with one of four types silica gels: SG, AminoSG, AOX-SG, and AOX-aminoSG. Formaldehyde in test air was removed in the early period in all types of SG by adsorption. With SG and AminoSG, however, formaldehyde removal decreased sharply and become zero within 20 d because of saturation of the gel by formaldehyde. With AOX-SG and AOX-aminoSG, removal of more than 90% of formaldehyde continued for more than 90 d. These results suggest that formaldehyde in the test air was adsorbed by silica gels and degraded by immobilized AOX. © 2014 The Society of Chemical Engineers, Japan.

A sensitive and easily distinguishable cobalt-free humidity indicator of porphyrin-silica gel-MgCl2 composite was prepared from pH-induced spectra changeable tetraarylporphyrin, silica gel (SiO2), and MgCl2. The pH change arose from proton release under dry conditions, and proton capture under humid conditions by a reversible reaction between MgCl2 and a silanol group of SiO2. A pink-orange porphyrin-Si(OH)2-MgCl2 composite was dried to give a green protonated porphyrin-SiO2Mg composite. The optimized concentrations of MgCl2 to make the concentrations of protonated porphyrin maximum under dry conditions were determined by absorption spectrometry of the green composite using a confocal laser scanning microscope as a microscopic spectrometer. Moreover, the green composite was prepared by heating dichloro(tetraarylporphyrinato)phosphorus chloride with MgCl2 and SiO2. The humidity-sensitivity of the green composite was evaluated by the absorption spectra under controlled humidity. A distinguishable color change of the green composite took place below 30% of relative humidity. 2011 © The Japan Society for Analytical Chemistry.

The IR spectra in the 13001450 cm-1 region, which reflect the CH and CH2 deformation vibrational modes of the succinate skeleton, have been investigated in detail for sodium dialkylsulfonates (alkyl groups: Ethyl, n-propyl, n-butyl, n-hexyl, n-heptyl, n-octyl, n-decyl, and n-dodecyl) and sodium 1,2-bis(2-ethylhexyl)sulfosuccinate (sodium 1,2-bis(2- ethylhexyloxycarbonyl)ethanesulfonate) (AOT). The results have provided clear evidence that two configurations, arising from the difference in the torsion angles of the succinate skeleton, are preferentially stabilized in aqueous solution as well as in the solid state, depending upon the concentration. Thus, the IR spectra of this region can be used as a powerful tool for elucidation of the mechanism of the disorderorder transition in aggregate systems of AOT or its homologs at the molecular level. © 2010 The Chemical Society of Japan.

In this work, fatigue fracture tests on liquid-repellent nanoporous silica micro-particles dispersed in water are reported; then, models of the grain cracking and fragmentation are proposed. Such tests can be regarded, from an external standpoint, as conducted under temporally variable but spatially uniform pressure distribution in the liquid surrounding the silica grains, or from an internal standpoint, as surface fatigue that occurs at the cyclical adsorption/desorption of water in/from the nanoporous particles. The test rig represents a compression-decompression cylinder divided into two chambers, one of constant volume and the other of variable volume. Silica is introduced inside the cavity of fixed volume, and a micro-filter is used to separate it from the chamber of variable volume, in which only water is supplied. Experimental results suggest that the fatigue fracture of silica particles occurs from the inside, explosion-like, oppositely to the previously reported implosion-like collapse of silica under wet pressurization. This is accompanied by enhancement of the hydrophilic silanol groups on the silica surface and by redistribution of the size of particles and pores. Critical numbers of cycles to achieve fracture of the silica particles obtained experimentally, and from the models of grain cracking and fragmentation, under cyclical pressurization, are in good agreement. © 2010 Springer-Verlag.
