  - JOURNAL OF CLEANER PRODUCTION - Rok 2020

  An important role in the consumption of electric energy in urban transport are non-traction needs (auxiliaries), the main part of which is heating and air condition (HVAC). Auxiliaries are responsible for almost half of total energy consumption (normal weather conditions) and in the winter (or hot summer) it reaches up to 70% in daily scale. The reduction of energy used for non-traction needs is currently the main challenge related...

  Międzynarodowy projekt UPGRID realizowany jest w ramach programu Horyzont 2020 (H2020). Program ten to największy jak dotąd program Unii Europejskiej (UE) w zakresie badań naukowych i innowacji. W projekcie UPGRID uczestniczy 17 partnerów z 9 krajów EU. Głównym celem projektu UPGRID jest rozwój funkcjonalności, które służą integracji sieci nn oraz SN ze stroną konsumencką. W ramach projektu wybrane technologie Inteligentnych Sieci...

  Reactions of [Cp*(OC)3M]Li (Cp* = C5Me5, M = Mo, W) towards t-Bu2P–PCl2 lead to the formation of phosphanylphosphinidene dimers [Cp*(OC)3M(η2-t-Bu2P–P)]2 in fairly good yields. The formation of a tetraphosphorus ligand proceeds via reductive dimerization of t-Bu2P–P units. NMR, X-ray investigations and DFT calculations show that the resulting tetraphosphorus ligand has a structure of dication t-Bu2P+=P–P=P+t-Bu2.
