Accelerated screening of colloidal nanocrystals using artificial neural network-assisted autonomous flow reactor technology.

Colloidal semiconductor nanocrystals with tunable optical and electronic properties are opening up exciting opportunities for high-performance optoelectronics, photovoltaics, and bioimaging applications. Identifying the optimal synthesis conditions and screening of synthesis recipes in search of efficient synthesis pathways to obtain nanocrystals with desired optoelectronic properties, however, remains one of the major bottlenecks for accelerated discovery of colloidal nanocrystals. Conventional strategies, often guided by limited understanding of the underlying mechanisms remain expensive in both time and resources, thus significantly impeding the overall discovery process.

A Newsletter/Text Message Intervention Promoting Beverage-Related Parenting Practices: Pilot Test Results.

Positive beverage parenting practices may reduce sugar-sweetened beverage consumption by children and prevent potential health problems. An online newsletter/text message intervention was conducted with parents of children 6 to 12 years to improve beverage parenting practices. Newsletters and text messages were sent weekly over a 4-week period providing gain-framed messages encouraging parenting practices including role modeling and controlling home beverage availability.

Gain-Framed Messages Were Related to Higher Motivation Scores for Sugar-Sweetened Beverage Parenting Practices than Loss-Framed Messages.

Parents play an important role in promoting healthy beverage intake among children. Message-framing approaches, where outcomes are described as positive (gain) or negative (loss) results, can be used to encourage parenting practices that promote healthy beverage intakes. This study tested the effectiveness of message framing on motivation for parenting practices targeting reductions in child sugar-sweetened beverage (SSB) intake (controlling availability, role modeling) and dispositional factors moderating effectiveness.

Beverage Intake among Children: Associations with Parent and Home-Related Factors.

Beverage intake can influence child diet quality in a positive or negative manner depending on the beverage type and amounts consumed. Parenting practices such as role modeling and control of home beverage availability have been associated with child beverage intake, whereas examination of the influence of parental beverage nutrition knowledge has been more limited. The purpose of this study was to examine the relationships between sugar-sweetened and dairy beverage intake among children (9-12 years) and home and parental factors.
