One-dimensional nanostructures of chalcogens and chalcogenides
This paper presents an overview of solution-phase methods for generating one-dimensional (1D) nanostructures of chalcogens and chalcogenides. The first part describes self-seeding techniques for the formation of pure Se, pure Te, and alloy nanostructures. Se and Te are interesting for their inherent properties such as chirality, photoconductivity, piezoelectricity, and high reactivity. The ...

Moringa oleifera functionalised sand – reuse with non-ionic surfactant dodecyl glucoside
Moringa oleifera seeds are well known for their ability to cause flocculation in turbid water and facilitate bacterial inhibition. These effects are due to the cationic polypeptide MO2.1, which affects the surface charge of suspended particles and causes lysis of bacterial cells. However, the attachment of bacteria to MO2.1 prevents further bacterial attachment, reducing the ...

Evaluation of hygroscopic cloud seeding in liquid-water clouds: a feasibility study
Abstract. An airborne cloud seeding experiment was conducted over the eastern coast of Zhejiang, China, on 4 September 2016 during a major international event held in Hangzhou. In an attempt to reduce the likelihood of rainfall onset, a major airborne experiment for weather modification took place by seeding hygroscopic agents to warm clouds to reduce cloud droplet size. The effectiveness of ...

Use of pressure manifestations following the water plasma expansion for phytomass disintegration
A prototype capable of generating underwater high-voltage discharges (3.5 kV) coupled with water plasma expansion was constructed. The level of phytomass disintegration caused by transmission of the pressure shockwaves (50–60 MPa) followed by this expansion was analyzed using gas adsorption techniques. The dynamics of the external surface area and the micropore volume on multiple ...

Injection techniques for bulk cell seeding decellularised vascular scaffolds
Tissue engineering small diameter vascular grafts requires excessive culture times to produce an appropriate extracellular matrix (ECM). The use of decellularised exogenous tissue as a scaffold has the potential to overcome this limitation due to the preformed ideal ECM architecture that remains after decellularisation. While this scaffold reduces ECM maturation times cell seeding is difficult ...

Science’s role in growing diverse, nutritious food
Can science meet the demand for more diverse and nutritious food? Jan Piotrowski investigates. The riots that swept Africa in 2007 and 2008 in response to the spiralling costs of staple crops brought the effects of food shortages into sharp focus. Images of unrest circled the globe, and the consequent instability brought to the forefront of political debate a question that had long been out of ...
