The morphology of polyimide nanocomposite with single-walled carbon nanotubes (CNT) was considered. The effect of CNT agglomeration and twisting into a bundle was incorporated by the proposed hierarchical helical bundle model. The bundle model was used in predicting the effective thermo-elastic properties of the nanocomposite. The micromechanical analytical models were found useful in predicting the effective thermo-elastic properties of the nanocomposite. Finite element micromechanical analysis was used to calculate the residual cooling stresses inside the nanocomposite matrix with carbon fiber reinforced composites. The reduced residual stresses and transverse coefficient of thermal expansion of unidirectional lamina in the case of nanocomposite matrix were attributed to the reduced mismatch between the thermo-elastic properties of matrix and fiber. Reduction in the residual processing stresses of the hybrid composite opens the way for the use of polymeric nanocomposites as matrices in carbon fiber reinforced materials.

The original version of this Article contained errors in Fig. 3. In Fig. 3a, the word 'fluid' in grey was incorrectly given as 'solid' in green, below that, 'solid' in green was previously 'fluid' in grey. Also, the label on the arrow incorrectly read 'TMG (1 mol%) HABI-Cl (3 mol%) 455 nm, 1 min'; the correct version reads 'TMG (1 mol%) HABI-O-n-oct (4 mol%) 455 nm, 4 min'. In the accompanying legend, the word 'photobase' was originally incorrectly given as 'photoacid'. Additionally, in Fig. 3b, the label on the central image was 'As is: solid', rather than the correct 'As is: fluid'. This has been corrected in both the PDF and HTML versions of the Article.

The highly sensitive optical detection of oxygen including dissolved oxygen (DO) is of great interest in various applications. We devised a novel room‐temperature‐phosphorescence (RTP)‐based oxygen detection platform by constructing core–shell nanoparticles with water‐soluble polymethyloxazoline shells and oxygen‐permeable polystyrene cores crosslinked with metal‐free purely organic phosphors. The resulting nanoparticles show a very high sensitivity for DO with a limit of detection (LOD) of 60 n m and can be readily used for oxygen quantification in aqueous environments as well as the gaseous phase.

The increase in human population as well as area development in Salatiga Groundwater Basin, Central Java Province, will increase the potency of groundwater contamination in that area. Groundwater quality, especially the shallow groundwater, is very vulnerable to the contamination from industrial waste, fertilizer/agricultural waste, and domestic waste. The first step in the conservation of groundwater quality is by conducting the mapping of the groundwater vulnerability zonation against the contamination. The result of this research was groundwater vulnerability map which showed the areas vulnerable to the groundwater contamination. In this study, groundwater vulnerability map was assessed based on the DRASTIC Method and was processed spatially using Geographic Information System. The DRASTIC method is used to assess the level of groundwater vulnerability based on weighting on seven parameters, which are: depth to the water table (D), recharge (R), aquifer material (A), soil media (S), topography (T), impact of vadose zone (I), and hydraulic conductivity (C). The higher the DRASTIC Index will result in the higher vulnerability level of groundwater contamination in that area. The DRASTIC Indexes in the researched area were 85 – 100 (low vulnerability level), 101 -120 (low to moderate vulnerability level), 121 – 140 (moderate vulnerability level), 141 – 150, (moderate to high vulnerability level), and 151 – 159 (high vulnerability level). The output of this study can be used by local authority as a tool for consideration to arrange the policy for sustainable area development, especially the development in an area affecting the quality of Salatiga Groundwater Basin.
