Advances in sorption-based AWH (SAWH) primarily focus on novel materials, often overlooking system-level considerations. We introduce the first-of-its-kind compact rapid cycling fuel-fired (CRCF) AWH device. The CRCF device packages aluminum fumarate MOF into a compact adsorbent heat exchanger (AHX), which uses fuel combustion and an ambiently cooled condenser. The CRCF prototype was designed to maximize volumetric production density (<span><span style=\"\"></span><span data-mathml='<math xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow is=\"true\"><msub is=\"true\"><mi is=\"true\">P</mi><mi is=\"true\">v</mi></msub></mrow></math>' role=\"presentation\" style=\"font-size: 90%; display: inline-block; position: relative;\" tabindex=\"0\"><svg aria-hidden=\"true\" focusable=\"false\" height=\"2.317ex\" role=\"img\" style=\"vertical-align: -0.582ex;\" viewbox=\"0 -747.2 1085.8 997.6\" width=\"2.522ex\" xmlns:xlink=\"http://www.w3.org/1999/xlink\"><g fill=\"currentColor\" stroke=\"currentColor\" stroke-width=\"0\" transform=\"matrix(1 0 0 -1 0 0)\"><g is=\"true\"><g is=\"true\"><g is=\"true\"><use xlink:href=\"#MJMATHI-50\"></use></g><g is=\"true\" transform=\"translate(642,-150)\"><use transform=\"scale(0.707)\" xlink:href=\"#MJMATHI-76\"></use></g></g></g></g></svg><span role=\"presentation\"><math xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow is=\"true\"><msub is=\"true\"><mi is=\"true\">P</mi><mi is=\"true\">v</mi></msub></mrow></math></span></span><script type=\"math/mml\"><math><mrow is=\"true\"><msub is=\"true\"><mi is=\"true\">P</mi><mi is=\"true\">v</mi></msub></mrow></math></script></span>), defined as the daily water production per unit volume of the AHX (<span><span style=\"\"></span><span data-mathml='<math xmlns=\"http://www.w3.org/1998/Math/MathML\"><mrow is=\"true\"><mi is=\"true\">k</mi><msub is=\"true\"><mi is=\"true\">g</mi><mrow is=\"true\"><mi is=\"true\">w</mi><mi is=\"true\">a</mi><mi is=\"true\">t</mi><mi is=\"true\">e</mi><mi is=\"true\">r</mi></mrow></msub><msubsup is=\"true\"><mrow is=\"true\"><mo stretchy=\"true\" is=\"true\">(</mo><msup is=\"true\"><mi is=\"true\">m</mi><mn is=\"true\">3</mn></msup><mo stretchy=\"true\" is=\"true\">)</mo></mrow><mrow is=\"true\"><mi is=\"true\">A</mi><mi is=\"true\">H</mi><mi is=\"true\">X</mi></mrow><mrow is=\"true\"><mo is=\"true\">−</mo><mn is=\"true\">1</mn></mrow></msubsup><mi is=\"true\">d</mi><mi is=\"true\">a</mi><msup is=\"true\"><mi is=\"true\">y</mi><mrow is=\"true\"><mo is=\"true\">−</mo><mn is=\"true\">1</mn></mrow></msup></mrow>&l","PeriodicalId":9703,"journal":{"name":"Cell Reports Physical Science","volume":"25 1","pages":""},"PeriodicalIF":8.9,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141754041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found that this reduction substantially mitigates the volume shrinkage below 3.98% compared to over 10% for commercial photosensitive resins. Precision improves significantly, with dimensional deviation at just 0.035% compared to over 0.1% with commercial options. Furthermore, due to the low filling ratio, the improvement in 3D printing precision did not affect the mechanical properties; thus, it does not affect applications where those photosensitive resins are originally targeted.

Nonactivated internal alkenes in these polymers can be effectively cleaved without elevated temperature or pressure. The oxidation process generates acetal as the main functionality, which can be used for further recycling. As a proof of concept, the oligomers with acetal end groups, resulting from the oxidation of polybutadiene, are shown to undergo transacetalization with polyols to form a polymer network.
