Building on this revival and re-emergence of hemp, we designed and fabricated hemp-based sustainable and robust slippery surfaces by coating hemp paper with beeswax and subsequently infusing it with hemp oil. A wide variety of aqueous liquids and beverages easily slide on our hemp-based sustainable slippery surfaces, without leaving a trace. We also fabricated hemp-based sustainable slippery surfaces using different textured metals. Our hemp-based sustainable slippery metal surfaces display good icephobic and antithrombotic properties. With these attributes, we envision that our hemp-based sustainable slippery surfaces will pave the path to more safe, non-toxic, and biodegradable or recyclable slippery surfaces for applications in food packaging, anti-icing or de-icing coatings, and antithrombotic medical devices.}, number={6}, journal={ACS SUSTAINABLE CHEMISTRY & ENGINEERING}, author={Sutherland, Daniel J. and Rather, Adil M. and Sabino, Roberta M. and Vallabhuneni, Sravanthi and Wang, Wei and Popat, Ketul C. and Kota, Arun K.}, year={2023}, month={Feb} } @article{rather_wani_ahmad_shaari_rather_2023, title={Superior Photocatalytic Dye Degradation and Adsorption Efficiency of Rgo-Mwcnt Modified Zno-Al2o3 Nanocomposites}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85162824166&partnerID=MN8TOARS}, DOI={10.2139/ssrn.4485407}, journal={SSRN}, author={Rather, R.A. and Wani, A.A. and Ahmad, N. and Shaari, N. and Rather, A.M.}, year={2023} } @article{xu_chang_yao_zhang_dupont_rather_bao_wang_2022, title={Modularizable Liquid-Crystal-Based Open Surfaces Enable Programmable Chemical Transport and Feeding using Liquid Droplets}, volume={34}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85128187895&partnerID=MN8TOARS}, DOI={10.1002/adma.202108788}, abstractNote={Abstract}, number={20}, journal={Advanced Materials}, author={Xu, Y. and Chang, Y. and Yao, Y. and Zhang, M. and Dupont, R.L. and Rather, A.M. and Bao, X. and Wang, X.}, year={2022} } @inbook{rather_xu_dupont_wang_2022, title={Polymeric Membranes in Wastewater Treatment}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85130564956&partnerID=MN8TOARS}, DOI={10.1007/978-981-16-3667-7_17}, booktitle={Nanoscale Engineering of Biomaterials: Properties and Applications}, author={Rather, A.M. and Xu, Y. and Dupont, R.L. and Wang, X.}, year={2022}, pages={487–515} } @article{rather_xu_chang_dupont_borbora_kara_fang_mamtani_zhang_yao_et al._2022, title={Stimuli-Responsive Liquid-Crystal-Infused Porous Surfaces for Manipulation of Underwater Gas Bubble Transport and Adhesion}, volume={34}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85125092907&partnerID=MN8TOARS}, DOI={10.1002/adma.202110085}, abstractNote={Abstract}, number={14}, journal={Advanced Materials}, author={Rather, A.M. and Xu, Y. and Chang, Y. and Dupont, R.L. and Borbora, A. and Kara, U.I. and Fang, J.-C. and Mamtani, R. and Zhang, M. and Yao, Y. and et al.}, year={2022} } @article{yao_bennett_xu_rather_li_cheung_bhanji_kreder_daniel_adera_et al._2022, title={Wettability-based ultrasensitive detection of amphiphiles through directed concentration at disordered regions in self-assembled monolayers}, volume={119}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85140271613&partnerID=MN8TOARS}, DOI={10.1073/pnas.2211042119}, abstractNote={Various forms of ecological monitoring and disease diagnosis rely upon the detection of amphiphiles, including lipids, lipopolysaccharides, and lipoproteins, at ultralow concentrations in small droplets. Although assays based on droplets’ wettability provide promising options in some cases, their reliance on the measurements of surface and bulk properties of whole droplets (e.g., contact angles, surface tensions) makes it difficult to monitor trace amounts of these amphiphiles within small-volume samples. Here, we report a design principle in which self-assembled monolayer–functionalized microstructured surfaces coated with silicone oil create locally disordered regions within a droplet’s contact lines to effectively concentrate amphiphiles within the areas that dominate the droplet static friction. Remarkably, such surfaces enable the ultrasensitive, naked-eye detection of amphiphiles through changes in the droplets’ sliding angles, even when the concentration is four to five orders of magnitude below their critical micelle concentration. We develop a thermodynamic model to explain the partitioning of amphiphiles at the contact line by their cooperative association within the disordered, loosely packed regions of the self-assembled monolayer. Based on this local analyte concentrating effect, we showcase laboratory-on-a-chip surfaces with positionally dependent pinning forces capable of both detecting industrially and biologically relevant amphiphiles (e.g., bacterial endotoxins), as well as sorting aqueous droplets into discrete groups based on their amphiphile concentrations. Furthermore, we demonstrate that the sliding behavior of amphiphile-laden aqueous droplets provides insight into the amphiphile’s effective length, thereby allowing these surfaces to discriminate between analytes with highly disparate molecular sizes.}, number={43}, journal={Proceedings of the National Academy of Sciences of the United States of America}, author={Yao, Y. and Bennett, R.K.A. and Xu, Y. and Rather, A.M. and Li, S. and Cheung, T.C. and Bhanji, A. and Kreder, M.J. and Daniel, D. and Adera, S. and et al.}, year={2022} } @article{shome_rather_borbora_srikrishnarka_baidya_pradeep_manna_2021, title={Design of a Waste Paper-Derived Chemically ‘Reactive’ and Durable Functional Material with Tailorable Mechanical Property Following an Ambient and Sustainable Chemical Approach}, volume={16}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85108334530&partnerID=MN8TOARS}, DOI={10.1002/asia.202100475}, abstractNote={Abstract}, number={14}, journal={Chemistry - An Asian Journal}, author={Shome, A. and Rather, A.M. and Borbora, A. and Srikrishnarka, P. and Baidya, A. and Pradeep, T. and Manna, U.}, year={2021}, pages={1988–2001} } @article{xu_rather_yao_fang_mamtani_bennett_atta_adera_tkalec_wang_2021, title={Liquid crystal–based open surface microfluidics manipulate liquid mobility and chemical composition on demand}, volume={7}, url={http://www.scopus.com/inward/record.url?eid=2-s2.0-85116613780&partnerID=MN8TOARS}, DOI={10.1126/sciadv.abi7607}, abstractNote={Liquid crystal surfaces enable manipulation of liquid mobility and cargo release via temperature, electrolytes, and light.}, number={40}, journal={Science Advances}, author={Xu, Yang and Rather, Adil M. and Yao, Yuxing and Fang, Jen-Chun and Mamtani, Rajdeep S. and Bennett, Robert K.

However, various complex and catalyst-based approaches have been adopted for chemical modification and integration of different functionalities in silk fibroin-based materials. Here, both tailored water wettability and mechanical property have been associated with silk microfiber reinforced silk fibroin sponges (SMFRSFSs) through the strategic introduction of β-sheets and a facile and catalyst-free chemical reaction at ambient conditions. While the controlled tailoring of β-sheets in the silk fibroin skeletal framework of the sponges allowed us to modulate the compressive modulus, the 1,4-conjugate addition reaction between amine residues of silk (fiber and fibroin) and acrylate groups of a multifunctional cross-linker provided residual chemical reactivity. Further, the chemically "reactive" sponge was postmodified with the selected alkylamines to introduce a wide range of water wettability (from 36 to 161°) without affecting the mechanical property. Thereafter, the silk cocoon-derived and extremely water-repellent sponge was used for environment-friendly cleaning of oil spillages through selective absorption-based and filtration-based oil/water separation at different and severe aqueous conditions.

However, often, poor chemical and physical durabitity of conventional thin special wettable materials stands in the way of prospective applications of this property at practical settings. A chemically “reactive” polymeric gel material is introduced here, and advantage is taken of the robust and facile 1,4-Michael addition reaction between acrylate and primary amine groups to develop a chemically cross-linked and bulk (including interior and surface) superhydrophobic material. A mixture of dipentaerythritol pentaacrylate and branched poly(ethylenimine) (BPEI) can rapidly form a self-standing gel network. On removal of solvent molecules, the synthesized gel network provides a highly porous and reactive polymeric matrix that can be further modified with a variety of small molecules to tailor the liquid water wettability on the synthesized material. This approach provides a facile and rapid proc...}, number={23}, journal={Chemistry of Materials}, author={Rather, A.M. and Manna, U.}, year={2016}, pages={8689–8699} }
