Thus, using low amounts of silane, we synthesized 3-aminopropyltrimethoxysilane (APTMS)-grafted SBA-15 mesoporous silica and evaluated its CO2 adsorption performance. APTMS-grafted SBA-15 samples were prepared using either impregnation or heating–filtration method (grafting). The obtained samples were characterized by X-ray diffraction spectroscopy, transmission electron microscopy, N2 adsorption/desorption, scanning electron microscopy, magic-angle spinning nuclear magnetic resonance, and elemental analysis. The results revealed that the micropores of SBA-15 were preferentially blocked, and APTMS increasingly occupied the mesopores with increasing amine loading. The CO2-adsorption performance of the adsorbents was measured by thermogravimetric analysis under dry conditions. Both synthesis methods achieved high amine immobilization efficiency (78.3–92.2%), as estimated from the amount of silane coupling agents used in the synthesis and that immobilized on the support. The adsorbents prepared by the two methods adsorbed similar amounts of CO2 of approximately 0.5 mmol g− 1 in 400 ppm CO2 and ~ 1.0 mmol g− 1 in 5 vol% CO2. The adsorption amounts attained in this study are comparable to those of previously reported silane-coupling-agent-modified adsorbents that were prepared with more silane. In contrast, the adsorption rate of the samples was affected by the synthesis method, even with similar amine loadings.

However, there have been relatively limited studies concerning the effect of varying contact gaps and bias voltages on the humidity sensor based on PSi. In this work, the nanostructure PSi layer was synthesized via the anodization method and fabricated at different annealing temperatures of 250 ℃, 450 ℃, 650 ℃, and 850 ℃. Subsequently, the four samples were deposited with varying gold (Au) contact gaps of 3.5 mm, 4.5 mm, 7.5 mm, and 8.5 mm. The morphological and structural characteristics of the PSi layer were characterized using scanning electron microscopy (SEM) and X-ray diffraction (XRD) analysis. The PSi-based humidity sensors with varied Au contact gaps were evaluated in a humidity chamber at 40–90% relative humidity (RH) levels with different bias voltages of 2 V, 5 V, and 10 V. The optimized fabricated PSi device was evaluated for its electrical behaviour using I-V measurement under various operating temperatures ranging from 25 °C to 100 °C.

To achieve this, (Cu) ink with ideal rheological properties and high particle loading is necessary. However, to date, no work focusing on systematic (Cu) ink development with (Cu) particle loading more than 95 (wt%) has been reported. Hence, in the present work, a novel (Cu) ink with a particle loading of more than 95 (wt%,) and polylactic acid (PLA) as a binder has been developed. The rheological behavior of the (Cu) ink with different amounts of (Cu) loading i.e. 93, 95 and 97 (wt%) respectively were investigated. Moreover, the modelling using the Herschel-Bulkey equation was done to establish the rheology. All the prepared inks showed viscoelastic and shear thinning behaviour. Moreover, the ink having 97(wt%) (Cu) loading exhibited optimum rheology with a shear elastic modulus of around ({10}^{5} Pa) in the linear viscoelastic area. Subsequently, DIW using the prepared (Cu) inks followed by sintering was performed. The morphological study of the 3D printed (Cu) green samples and sintered samples was performed and it was found that the variation in (Cu) particle loading significantly affected the density and volumetric shrinkage. Finally, an HP-({text{Cu}}) sample having a pore size less than 200 (mu m) was fabricated using DIW and sintering to validate the efficacy of the developed (Cu) ink. Proper interparticle bonding between the (Cu) particles was observed indicating that the developed ink is suitable for the fabrication of complex (Cu) parts for lithium metal battery application.</div>","PeriodicalId":660,"journal":{"name":"Journal of Porous Materials","volume":"31 4","pages":"1231 - 1245"},"PeriodicalIF":2.5,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140581068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
