Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

Rice flash Joule heating process recycles plastic from end-of-life F-150 trucks into high-value graphene for new vehicles

Green Car Congress

To test whether end-of-life, mixed plastic could be transformed, the Rice lab ground the shredder fluff made of plastic bumpers, gaskets, carpets, mats, seating and door casings from end-of-life F-150 pickup trucks to a fine powder without washing or pre-sorting the components.

Researchers find annealing significantly reduces interface resistance in all-solid-state-batteries

Green Car Congress

Before completing the fabrication of a battery, the team exposed the LiCoO 2 surface to air, nitrogen (N 2 ), oxygen (O 2 ), carbon dioxide (CO 2 ), hydrogen (H 2 ), and water vapor (H 2 O) for 30 minutes. The team next heated the sample at 150°C for an hour in battery form i.e. with the negative electrode deposited. 1c17945.

ExxonMobil, UC Berkeley, Berkeley Lab develop new MOF for carbon capture and steam regeneration

Green Car Congress

Power plants strip CO 2 from flue emissions today by bubbling flue gases through organic amines in water, which bind and extract the carbon dioxide. The liquid is then heated to 120-150 ?C F) to release the CO 2 gas, after which the liquids are reused. (UC Berkeley graphic by Eugene Kim). C (250-300 ?F) Kim, Rebecca L.

Scientists develop method for direct conversion of methane to methanol or acetic acid under mild conditions

Green Car Congress

Three-hour-long batch-reactor tests conducted at 150 ˚C, using either the zeolite-supported or the titanium-dioxide-supported catalyst, yielded around 22,000 micromoles of acetic acid per gram of catalyst, or around 230 micromoles of methanol per gram of catalyst, respectively, with selectivities of 60–100%. Rhodium loadings of 0.5
