Designing the highest melting point substance

Designing the highest melting point substance

Using computer modelling, researchers at Rhode Island’s Brown University have predicted that HfN0.38C0.51 a material made from hafnium, nitrogen, and carbon would have the highest known melting point – 4,400K.

The experimental record-holder, according to the university, is made from hafnium, tantalum, and carbon (Hf-Ta…

3d printed lathe

As someone who owns a couple of lathers (and can almost use them) and is interested in 3d printing, I was rather intrigued by this 3d printed lathe.
Delightfully recursively, it has only been made to clean up 3d printed pulleys destined for a 3d printer.

The quick version is: a Dell Inspiron 530 will happily run Windows 7 – 32bit or 64bit – as Win7 has all the appropriate…

Jewel-like open-frame dc-dc

Measuring only 15 x 14mm and 11mm high, Murata’s MTC1 series of 1W pcb-mount dc-dc converters is a welcome visual change from the little black cubes I have grown to expect.

I realise this is an artist’s impression, so it might not quite look like this…

CanSats - cheap satellite design discipline for kids

Our omniscient web editor drew my attention to CanSats – non-space proto-satellites intended to give young people a taste of design-for-space.

The size – 115 mm height and 66 mm diameter, to fit in a fizzy drinks can – was proposed for space flight by Bob Twiggs, or so…

Direct sunlight to hydrogen recipe is a lot like solar cells.

Direct sunlight to hydrogen recipe is a lot like solar cells.

Apparently, tungsten diselenide can enable sunlight to split water into hydrogen and oxygen without the intervention of a photovoltaic cell and electrolysis.

And researchers at the Swiss Ecole Polytechnique Fédérale De Lausanne have found a cheap way to integrate WSe2 into a solar cell that gives off hydrogen…
