The output power of conventionally printed TEGs in the “π-type” geometry suffers due to low thermal voltage and low current because of high thermal and electrical contact resistance, respectively. Herein, a type of printed p–n junction TEGs (PN-TEGs) as a possible remedy is explored. Two printed PN-TEGs with different thicknesses are fabricated using printed p-type Bi<sub>0.5</sub>Sb<sub>1.5</sub>Te<sub>3</sub> and n-type Bi<sub>2</sub>Te<sub>2.7</sub>Se<sub>0.3</sub> materials. The PN-TEGs show a promising way to minimize the influence of thermal and electrical resistance in printed TEGs. In the experimental and simulation results, the significant impact of PN-TEGs’ dimensions on their power outputs is revealed. Also, a conventional “π-type” printed TEG is fabricated and its performance is studied. The optimized PN-TEG with a single thermocouple yields ≈14 times higher power output density of 5.3 μW cm<sup>−2</sup> at a Δ<i>T</i> of 25 K compared to “π-type” printed TEGs.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"7 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reported the preparation of CPEs based on boron moiety, poly(ethylene glycol) (PEG), and octahedral polyhedral oligomeric silsesquioxane (POSS) via in situ thermal polymerization method directly onto the lithium anode to improve the interfacial contact and electrochemical performance. The synergistic effect between the incorporation of anion-trapping boron moiety and in situ polymerization rendered the QSPEs exhibiting higher electrochemical voltage window, ionic conductivity, and transference number as well as better electrochemical performance than the PEG-based counterpart. Due to the Lewis acid effect, anion-trapping boron moiety could promote the dissociation of lithium salts, allowing more lithium ions to be in the free state, thereby enhancing the lithium-ion conductivity. With an optimal addition of POSS, the as-prepared CPEs exhibited lower overpotential during the lithium plating-stripping test and better electrochemical performance than the QSPE counterparts. The optimal POSS addition could facilitate the lithium-ion conduction and establishment of continuous ion pathways, further improving their electrochemical performance. This study pointed a promising approach for developing high performance lithium-ion batteries.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"68 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using parallel tempering molecular dynamics, structural distribution as a function of temperature is calculated in the entire temperature range. Low-energy structures are identified through a combination of structural optimization and Wulff–Kaischew construction which are then used to explore the energy landscape. The potential energy surface (PES), which is energy as a function of translation and rotation, is calculated for a few Au nanoclusters along specific directions on carbon lattice. Minimum-energy pathways are identified on the PES indicating a reduced barrier for pathways involving simultaneous rotation and translation. Diffusion simulations of Au<sub>233</sub> on graphite show that diffusion mechanism is directly related to the PES, and the information of the cluster pinning events is already present in the PES. Finally, a comparison of various interaction models highlights the importance of reasonably correct Au–C interactions which is crucial for studying the energy landscape and cluster sliding.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"97 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although promising for adsorption, many high-surface-area polymer materials cannot be easily processed into freestanding membranes or packed bed columns, due to poor solution processability and high back pressures, respectively. The preparation of hybrid membranes comprising sulfonated hypercrosslinked polymers entrapped in nanocellulose papers is described. The hybrid membranes are effective for simultaneous ultrafiltration and ion exchange. Increasing the polymer loading of the hybrid membrane produces synergy by increasing the permeance of the membranes while enhancing the ion adsorption capacity to values exceeding those of bulk hypercrosslinked polymers. The maximum ion adsorption capacity for copper is determined to be ≈100 mg g<sup>−1</sup> outperforming that of pure polymer (71 mg g<sup>−1</sup>) and commercially available ion exchange resins. Competitive adsorption is tested in samples containing water hardness elements and trace toxic metal ions showing high ion-exchange capacities. Even when fully loaded with water hardness elements, Ba<sup>2+</sup> and Sr<sup>2+</sup> are still removed from solution.","PeriodicalId":29791,"journal":{"name":"Small Science","volume":"192 1","pages":""},"PeriodicalIF":12.7,"publicationDate":"2024-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141931603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
