Thermoelectric Performance of Perovskite-type Oxide Materials

The prevailing strategies for heat and electric-power production that rely on fossil and fission fuels are having a negative impact on the environment and on our living conditions.

Self-assembled titanium calcium oxide nanopatterns as versatile reactive nanomasks for dry etching lithographic transfer with high selectivity.

Marco Faustini et al.

Nanoscale, 5(3), 984-990 (2012-12-19)

We report the simple preparation of ultra-thin self-assembled nanoperforated titanium calcium oxide films and their use as reactive nanomasks for selective dry etching of silicon. This novel reactive nanomask is composed of TiO(2) in which up to 50% of Ti

An inventory of trace elements inputs to French agricultural soils.

E Belon et al.

The Science of the total environment, 439, 87-95 (2012-10-16)

The inputs of ten trace elements (As, Cd, Cu, Cr, Hg, Mo, Ni, Pb, Se, Zn) to French agricultural soils have been assessed. The six main sources considered were: pesticides, mineral fertilizers, animal manure, liming materials, sludge and composts and

Nano-size layered manganese-calcium oxide as an efficient and biomimetic catalyst for water oxidation under acidic conditions: comparable to platinum.

Mohammad Mahdi Najafpour et al.

Dalton transactions (Cambridge, England : 2003), 42(14), 5085-5091 (2013-02-12)

Inspired by Nature's catalyst, a nano-size layered manganese-calcium oxide showed a low overvoltage for water oxidation in acidic solutions, which is comparable to platinum.
