Novel Preparation and Characterization of Zinc Ricinoleate Through Alkali Catalysis.

The enhanced thermal and chemical stability of Zinc oxide-based materials make them excellent candidates for the removal of odor-producing pollutants and compounds. The zinc salt of ricinoleic acid, commonly known as zinc ricinoleate, is viewed as the top performer. This article describes an innovative two-step synthesis of zinc ricinoleate, where the first step consists of the preparation of an intermediate compound, methyl ricinoleate, which is synthesized via transesterification of castor oil with methanol and catalyzed by sodium hydroxide.

Grafting of Poly(ethylene imine) to Silica Nanoparticles for Odor Removal from Recycled Materials.

One of the major obstacles to the reuse of recycled plastic materials is the emanation of after-process odors from recycled polymers and composites. Typically, recycled polymers are blended with an off-odor adsorbent additive in the recycling chain to eliminate these smells. This article describes an innovative ultrasonically assisted method of grafting poly(ethylene imine) (PEI) to silica nanoparticles (SiO) initiated by benzoyl peroxide (BP) which acts as an odor remover.

Development and Characterization of Integrated Nano-Sensors for Organic Residues and pH Field Detection.

Meeting global water quality standards is a real challenge to ensure that food crops and livestock are fit for consumption, as well as for human health in general. A major hurdle affecting the detection of pollutants in water reservoirs is the lapse of time between the sampling moment and the availability of the laboratory-based results. Here, we report the preparation, characterization, and performance assessment of an innovative sensor for the rapid detection of organic residue levels and pH in water samples.

Stretchable and Highly Permeable Nanofibrous Sensors for Detecting Complex Human Body Motion.

Wearable strain sensors have been attracting special attention in the detection of human posture and activity, as well as for the assessment of physical rehabilitation and kinematics. However, it is a challenge to fabricate stretchable and comfortable-to-wear permeable strain sensors that can provide highly accurate and continuous motion recording while exerting minimal constraints and maintaining low interference with the body. Herein, covalently grafting nanofibrous polyaniline (PANI) onto stretchable elastomer nanomeshes is reported to obtain a freestanding ultrathin (varying from 300 to 10 000 nm) strain sensor that has high gas permeability (10-33 mg h ).
