Confinement-Controlled Crystallization of Guanine

Guanine crystals are frequently encountered in nature in the beta-polymorph to create structural colors, to enhance the vision of creatures, and for camouflage. Unfortunately, it is challenging to control the crystallization of guanine in aqueous condition ...

High-Throughput Nanopore Fabrication and Classification Using Xe-Ion Irradiation and Automated Pore-Edge Analysis

Aleksandra Radenovic, Andras Kis, Martina Lihter, Mukesh Kumar Tripathi, Mukeshchand Thakur, Sanjin Marion, Michal Daniel Macha

Large-area nanopore drilling is a major bottleneck in state-of-the-art nanoporous 2D membrane fabrication protocols. In addition, high-quality structural and statistical descriptions of as-fabricated porous membranes are key to predicting the corresponding ...

Pretreatment options for micropollutant abatement before aquifer recharge in drinking water production: Assessment of UV/H2O2 and dense membranes

Robin Wünsch

Micropollutants (MP) such as residues of pharmaceuticals, industrial chemicals or pesticides can be detected in almost all water resources. Various processes can be used to abate them in drinking water treatment, e.g., ozonation, advanced oxidation process ...

SnSb binary alloy induced heterogeneous nucleation within the confined nanospace: Toward dendrite-free, flexible and energy/power dense sodium metal batteries

Dou Du, Yujie Liu

Rechargeable sodium (Na) metal batteries (SMBs) provide an alternative energy-dense, low-cost energy storage system beyond prevailing Li-ion technologies. However, their practical deployment requires the performance evaluation of Na anodes on the device le ...

2D nanopores: fabrication, energy harvesting and field-effect sensing

Michael Graf

Solid-state nanopores are man-made, nano-sized openings in membranes separating two chambers containing an electrolyte solution. When applying an electric field across the membrane, the nanopore provides the only path for mobile ions to pass from one side ...

Energy performance and economic feasibility of energy segmental linings for subway tunnels

Lyesse Laloui, Alessandro Francesco Rotta Loria, Benoît Claude Henri Cousin

This study focuses on the analysis of the energy performance and economic feasibility of so-called tunnel energy segmental linings: an innovative technology that couples the structural support role of the tunnel lining with the heating-cooling role of the ...

Fabrication and practical applications of molybdenum disulfide nanopores

Aleksandra Radenovic, Martina Lihter, Mukeshchand Thakur, Michael Graf, Ke Liu, Jiandong Feng

Among the different developed solid-state nanopores, nanopores constructed in a monolayer of molybdenum disulfide (MoS2) stand out as powerful devices for single-molecule analysis or osmotic power generation. Because the ionic current through a nanopore is ...

Osmotic power generator

Aleksandra Radenovic, Jiandong Feng

An osmotic power generator comprising an active membrane supported in a housing, at least a first chamber portion disposed on a first side of the active membrane for receiving a first electrolyte liquid and a second chamber portion disposed on a second sid ...

Programmable Multistable Mechanisms: Design, modeling, characterization and applications

Mohamed Gamal Abdelrahman Ahmed Zanaty

Multistable Mechanisms are mechanical devices having more than one stable state. Since these mechanisms can maintain different deformations with zero force, they are advantageous for low power environments such as wristwatches and medical devices. In this ...
