The Guardian newspaper has just produced a 15 page booklet on Women in Engineering.  It is full of stories about different sectors, articles on current issues, as well as many profiles.

e) 19th July, Astrophysics Lecture 6:30pm, Swinburne University
Lecturer is Dr Kim Ellis, Swinburne University.  The topic is yet to be announced.  Check here for details.

f) 28th August: Girls in Physics Breakfast at Monash University

This is our fourth year of running Girls in Physics Breakfasts. The aims of the program are:

  • to encourage girls in Years 10 to 12 to appreciate the diversity of careers that studying physics enables,
  • to appreciate the satisfaction that comes from a challenging career in science, and
  • to be aware of the success that women can achieve in the physical sciences.

The one remaining Breakfast for this year is on 28th August at Monash University, Clayton campus, see details below.
At each breakfast, students share a table with two or three women who are either have a career in physics or engineering, or are at university as undergraduates or postgraduates.  At the table, discussion ensures about what the women do, what they like about it as well as their training, future prospects, etc.  As a student at one of  early breakfasts told her teacher, ‘I was talking to a guest at my table and her career sounded so amazing.  Then I realised that in 8 years that could be me.  I got so excited.

There is also a guest speaker at each breakfast who presents a talk on her area of expertise.  After the talk there are activities on Careers in STEM and Q & A panel with three of the guests.

The date, venue, speaker, topic and Trybooking link is:

  • 28th August, Clayton Speaker: Dr Helen Maynard-Casely, ANSTO. Topic: How neutrons can save the world. Closing date: 4:00pm, 19th August.  Trybookings.

Further details: For promotional flyer and more details on the talk, etc, go to our website.
Numbers:  There is an initial maximum of  6 students per school, to ensure that more schools that can participate. On 8th August, spots will be opened up to schools that have already booked.
Cost: $15 per student with teachers free, a discounted fee is available to schools with a low ICSEA rank.
See the specific Trybookings link for details.

5.   Physics from the Web
Items selected from the bulletin of the Institute of Physics (UK).
Each item below includes the introductory paragraphs and a web link to the rest of the article.
a) ‘Thermal inductor’ could convert boiling water to ice with no energy input

A consequence of the second law of thermodynamics is that heat spontaneously flows from hot to cold, not the other way around. But now researchers in Switzerland have now shown that, if two reservoirs at different temperatures are connected using a passive thermoelectric element, “thermal inertia” can allow the hot reservoir to cool down to below the temperature of the cold reservoir. While this does not violate the second law, thermoelectic materials available today are not good enough for the effect to be exploited in practical devices. However, the researchers believe it could one day be used in refrigeration.

The thermoelectric effect is a well-known phenomenon whereby some materials convert a temperature difference into a potential difference. Heating one end of a metal, for example, causes the excited electrons at the hot end to diffuse towards the cold end. The effect also works in reverse: applying an electric current to a thermoelectric material leads creates a temperature gradient. This is the basis of thermoelectric coolers, which are widely used in computers, hotel minibars and other situations where the compressor required by a standard refrigerator would be unfeasible.
b) New ‘flexoelectret’ material could create high voltages when bent
A soft dielectric material that could create a relatively high voltage when bent has been created by physicists in China. Qian Deng and colleagues at Xi’an Jiaotong University describe their material as the first-ever “flexoelectret”. It was made by embedding a charged polymer layer in the middle of a dielectric silicone rubber material. With some improvements, the new material could find a wide range of applications including wearable electronics.

When some materials are deformed non-uniformly, a strain gradient drives positive and negative ions apart to create a voltage across the material. Known as flexoelectricity, this effect is observed in many dielectric materials, including crystals, polymers, and semiconductors

c) Mimicking squid skin to improve thermoregulating blankets

Engineers at the University of California, Irvine, have made a new and improved space blanket that allows users to control their temperature. The blanket, inspired by the adaptive properties of cephalopod skin, comprises a soft and stretchable polymer matrix that is transparent to infrared radiation covered with an array of infrared-deflecting metal domains anchored within the matrix.

Reflecting infrared radiation (heat) is important for many technologies, including electronic circuits, aircraft and spacecraft components, hospital warming devices, building insulation and speciality textiles and clothing. The drawback to most infrared-deflecting materials, however, is that they are static and unable to respond and adapt to changing environmental conditions. Although some adaptive systems have been developed, they are relatively expensive, energy inefficient and cumbersome.

Among passive thermal management systems, the “space blanket”, developed by NASA in the 1960s, is one of the most well-known. It generally consists of a plastic sheet overlaid with a thin continuous layer of metal such as aluminium. This hybrid structure, which has remained fundamentally unchanged since its conception, is very efficient at reflecting infrared radiation. It is thus routinely employed, in its various forms, in applications such as packaging and emergency covering.  Athletes also use it as a protective shield that prevents them from losing too much body heat after a race.
