Dementia Care Work in Singapore: Embodied Relations and Power Dynamics.

Based on research at a dementia day-care center in Singapore, I discuss how embodied care relations proceed amidst cultural expectations on aging, dementia, and care work. Engaging with approaches that conceptualize "care" as either empathy or control, I argue that care between older people with dementia, their families, and care workers can be understood as a reiterative, dialogic process whereby care participants strive to keep pace with each other, however briefly, due to cognitive decline, care workers' own limitations, and particular family difficulties. Care vacillates between practices of control, surveillance, and recognition, and comprises dynamic rather than enduring power relations.

Green synthesis of mesoporous MnNbOx oxide by a liquid induced self-assembly strategy for low-temperature removal of NOx.

Herein, we present a facile, sustainable, and highly efficient ionic liquid induced self-assembly protocol to construct a highly porous MnNbOx oxide with exceptionally high catalytic activity for NOx removal at low temperatures and excellent tolerance to H2O and SO2 poisoning.

A facile strategy for the synthesis of ferroferric oxide/titanium dioxide/molybdenum disulfide heterostructures as a magnetically separable photocatalyst under visible-light.

Semiconductor photocatalysts is a promising approach to combat both environmental pollution and global energy shortage despite the challenges of recycling and stability. In this paper, magnetic Fe3O4 particle is introduced in the system and Fe3O4/TiO2/MoS2 heterostructures can be formed in a facile strategy. The morphology and structure of Fe3O4/TiO2/MoS2 can be controlled by adjusting the hydrolysis rate of the titanium source. MoS2 is designed to fill in the mesoporous of TiO2 core, forming heterojunction on the surface and near-surface of TiO2 under solvothermal conditions. With respect to the decomposition of a rhodamine B (RhB) solution under visible light, the Fe3O4/TiO2/MoS2 heterostructures display highly photocatalytic activities in aqueous solutions, and they can be easily recovered to realize cyclic utilization by applying an external magnetic field. Thus, the effective magnetic recycle of the catalyst is achieved, and high visible light catalytic activity is ensured simultaneously. Since the current method is simple and flexible to create recyclable catalysts with high stability in this way, it could promote the practicability of semiconductor photocatalysts in water treatment, degradation of dye pollutants, and environmental cleaning.
