Experimental analysis of the fatigue life of threaded pipe connections under cyclic bending [PDF]

, 2012
When subjected to cyclic loads, fatigue cracks can cause failure of pipe systems joined by threaded pipe connections. In this study, the effect of contact conditions and coupling geometry is investigated experimentally. Fatigue tests under cyclic bending

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Positive‐Tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet‐Etching

Advanced Functional Materials, EarlyView.
A butyldithiocarbamic acid (BDCA) etchant is used to fabricate various micro‐ and nanoscale structures on amorphous antimony trisulfide (a‐Sb2S3) thin film via femtosecond laser etching. Numerical analysis and experimental results elucidate the patterning mechanism on gold (reflective) and quartz (transmissive) substrates.

Tree fruit cuttings propagated: Vegetative propagation of softwood cuttings of certain tree fruit rootstocks achieved by chemical and mist treatments

California Agriculture, 1957
Tree fruits are usually propagated by budding or grafting on seedling root-stocks but such seedlings tend to show more or less variability in many characteristics, including resistance to nematodes and diseases.

Clonal Propagation of Broussonetia Papyrifera by Stem and Root Cuttings

Journal of Science and Technology (Ghana)
Broussonetia papyrifera, locally known as ‘York’, is an introduced tree species in Ghana due to its potential for industrial cellulose, pulp, and paper production. Its unwanted spread in forest areas due to the introduction of both male and female plants has called for its control using approaches such as establishment of only male populations.
