The obtained nitrogen- and sulfur-doped porous carbons (NSPCs) possess 3D hierarchical porous structure and contain a significantly high amount of N and S species. The concurrent incorporation of N and S successfully modified the surface properties of carbon materials and lead to enhanced capacitive performance. The presented NSPC exhibits specific capacitance of 230 F g(-1) at a current density of 1 A g(-1) and showed excellent cycling stability, depicting a promising material for energy storage devices.</p>1 aMehare, Rupali, S.1 aRanganath, Suresha, P.1 aChaturvedi, Vikash1 aBadiger, Manohar., V.1 aShelke, Manjusha, V.  uhttp://library.ncl.res.in/content/situ-synthesis-nitrogen-and-sulfur-enriched-hierarchical-porous-carbon-high-performance02320nas a2200241   4500008004100000245009000041210006900131260000800200300001700208490000700225520145900232100003701691700002201728700003101750700002301781700002501804700002501829700002701854700002501881700003601906700002801942856010801970       2019                        eng d00aStudies on the use of sodium polyacrylate (SPA) for low-salt animal skin preservation0 aStudies on the use of sodium polyacrylate SPA for lowsalt animal  cSEP  a 27100-271110 v263 a<p>Salt-based preservation is practiced for decades in the leather industry because of its versatility, cost-effectiveness, and availability. The salt removed from the soaking process causes significant pollution including organic and elevated total dissolved solids (TDS). Hence, a low-salt skin preservation method using commercial sodium polyacrylate with a reduced quantity of sodium chloride aiming to retain leather properties and pollution reduction was the principal focus of the study. Commercial sodium polyacrylate initially characterized for water absorption capacity along with structural and functional properties is confirmed by NMR and IR spectroscopic techniques. In preliminary experiments, the process parameters attained optimized conditions of sodium polyacrylate (SPA) quantity (5%), a minimal amount of salt (15%), and contact time (4 h) required for skin preservation. Besides, reusability studies after SPA recovery (95%) were applied to skins with an optimized quantity of SPA and salt subsequently stored for 15 days along with control (40% salt). The results revealed that SPA with low salt aided an adequate curing efficiency with a substantial reduction (&gt; 65%) of TDS and comparable physical and organoleptic properties on par with the conventional method. Overall, SPA supported low-salt skin preservation reduces pollutant load (TDS) caused due to using of 40% sodium chloride in the conventional curing process.</p>
