温度，湿度，炭酸ガス濃度の養生条件を要因として，異なる3種類のセメント系結合材を用いたモルタルを促進炭酸化養生し，各種物性を取得した．その結果，配合によって炭酸化深さが大きくなる養生条件が異なり，炭酸ガス濃度の増大によって炭酸化深さが減少する場合があることを示すとともに，γ-2CaO.SiO2を含むモルタルは炭酸ガス濃度が高いほどCaCO3の生成量が多くなり，空隙を充填する効果が大きくなることを明らかにした．さらに，実験結果をふまえてトリチウム水を対象として物質遮断性を試算した結果，炭酸ガス濃度が高いほど物質浸透量は少なくなることを示した．
Graphene oxide (GO) monolayers were transferred onto SiO2/Si substrates by Langmuir-Blodgett (LB) technique and were converted to reduced graphene oxide (RGO) by exposure to hydrazine vapors followed by various durations of heat treatment at 400 °C in Ar atmosphere. Bottom gated FETs were fabricated with LB grown mono…
Electric field-dependent permittivity of n-TiO2 (rutile) along different crystallographic axes was investigated by an electrochemical impedance spectroscopy (EIS) measurement. The C−2 versus U plots were fitted with a quadratic function of U, derived from a model that adds the effects of electric field dependent permi…

Nano powders (NPs) are common and frequently employed in industry, and the iron is mostly applied in high-performance magnetic materials and pollutants treatment for groundwater, and the zinc is widely used in brass, bronze, die casting metal, alloys, rubber, and paints, etc. Nonetheless some disasters induced by meta…
In the present study, the adaptive neuro-fuzzy inference system (ANFIS) is developed for the prediction of effective thermal conductivity (ETC) of different fillers filled in polymer matrixes. The ANFIS uses a hybrid learning algorithm. The ANFIS is a class of adaptive networks that is functionally equivalent to fuzzy…
BaZrxTi(1-x)O3 (x = 0∼0.15) (BZT) thin films were prepared by chemical solution deposition. LaNiO3 buffer layer was introduced to modify the structure and ferroelectric properties of the films.
