Beginning computer science students often have great difficulty with the analysis and design of solutions to programming related problems. Using the Shuttle Puzzle problem as a vehicle the process of analyzing a problem and synthesizing observations into an algorithm is presented in a detailed, step-by-step manner. Introduction When I was child and went to visit my grandparents, I would often e...

The study of particle stabilized interfaces has a long history in terms of emulsions, foams and related dry powders. The same underlying interfacial energy principles also allow hydrophobic particles to encapsulate individual droplets into a stable form as individual macroscopic objects, which have recently been called "Liquid Marbles". Here we discuss conceptual similarities to superhydrophobi...

The marble burying test is a simple behavioral psychopharmacology task in which rodents, especially rats and mice, are exposed to glass marbles laying on thick bedding materials. This test has been widely used to assess the effects of a variety of psychoactive drugs. Although the marble burying test clearly reflects drug efficacy, many aspects of the behavior itself remain unclear. In the prese...

Liquid marbles have been shown to be a novel micro-reactor to synthesize polyperoxides by the radical alternating copolymerization of the 1,3-diene monomer with oxygen in a good yield. Oxygen gas is effectively absorbed as a comonomer by the large and permeable gas-liquid interface of the liquid marbles.

Liquid marbles are micro reservoirs of fluid surrounded by a powder shell. Their unique properties show promise for high-value technological applications in the medical, biotechnology, chemical and pharmaceutical industries. In this study, liquid marbles were prepared from six mixtures of water and glycerol by releasing droplets from different heights onto a loosely packed powder bed using a 1m...

Ag nanowire-based catalytic liquid marbles are fabricated as miniature reactors, which demonstrate highly efficient, support-free and rate-controllable heterogeneous degradation of methylene blue, with catalytic efficiency close to 100%. Our miniature catalytic liquid marbles are essential for reactions involving highly toxic/hazardous or costly reactants, where small volume preliminary reactio...
