• The new version of the European Union's Energy Performance of Buildings Directive has been published and will take effect July 9. The directive is the EU's main legislative instrument designed to promote improved energy performance of buildings. Member states will have 20 months to transpose the new elements into national law.
• A proposal to use microencapsulated phase change material to help motor vehicles run smoothly in extreme cold has won the ClimateLaunchpad competition in Azerbaijan. A team of chemical engineering students from Baku Higher Oil School developed the concept. The team will represent Azerbaijan at the ClimateLaunchpad finals in Scotland Nov. 1-2, 2018.
• New from Research Reports: "2018 Global Inorganic PCMs Industry Report – History, Present and Future"
U.S. patent application 20180187977 (applicant SGL Carbon SE, Wiesbaden, Germany):
"The use of a composite material for heat management in the electrical and/or electronic area, in particular in a car. A grid-like structure filled with a phase change material (PCM), and to a composite material that includes a grid-like structure filled with PCM. The filled grid-like structure being present on a cover layer or between two cover layers."
U.S. patent application 20180185189 (applicant Zeltiq Aesthetics Inc., Pleasanton, Calif.):
"A treatment system for cooling subcutaneous lipid-rich cells  in a human subject includes an applicator  and a control unit. The treatment system has a cooling mode for cooling tissue and a heating mode for warming tissue. The control unit includes a circulation circuit in fluid communication with the applicator, a chiller apparatus configured to chill fluid from the applicator circulation circuit, and a heater apparatus to warmed fluid from the applicator circulation circuit. ... The chilled reservoir can hold coolant (referred to as 'chilled coolant') at a relatively low temperature and the chiller fluidic circuit can include, without limitation, a refrigeration unit, a cooling tower, a thermoelectric chiller, a cartridge of phase change material, or any other device capable of removing heat from coolant."
U.S. patent application 20180191295 (applicant Saudi Arabian Oil Co., Dhahran, Saudi Arabia):
"A solar power system includes a plurality of solar power cells mounted on an outer surface of a spherical frame, the spherical frame including an inner surface that defines an interior volume; a heat sink that includes a hollow housing mounted within the interior volume of the spherical frame; and a phase change material positioned in the hollow housing of the heat sink, the phase change material thermally coupled to the inner surface of the spherical frame to receive heat from the outer surface of the spherical frame."
U.S. patent application 20180184707 (applicant Philip Morris Products SA, Neuchâtel, Switzerland):
"A portable extinguisher for extinguishing a single smoking article [S] at a time, the extinguisher comprising: a reservoir; a chamber sized to receive at least part of a single smoking article; and an opening to receive at least part of the smoking article into the chamber; wherein the reservoir and the chamber are thermally coupled and wherein the chamber is isolated from the reservoir such that there is no fluid communication between the chamber and the reservoir, and wherein the reservoir contains a phase change material arranged such that, in use, heat energy from a smoking article received in the chamber is absorbed by a phase transition of the phase change material."
