Electromagnetic Interference (EMI) shielding performance of lightweight Metal decorated Carbon nanostructures dispersed Polyvinylidene fluoride flexible films

03-Jul-2018 | Kumaran - Rengaswamy; Dinesh Kumar Sakthivel; Alagar Muthukaruppan; N. Balasubramanian; Subramanian Venkatachalam; ..., New Journal of Chemistry, 2018

We report electromagnetic interference shielding of metals decorated MWCNT/rGO in polyvinylidene fluoride (PVDF) flexible films. X-ray diffraction patterns show the presence of metallic nanoparticles firmly bound with carbon fillers of the composite. The morphological studies proved the ...

Repurposing bacterial extracellular matrix for selective and differential abstraction of rare earth elements

03-Jul-2018 | Pei Kun R. Tay; Avinash Manjula-Basavanna; Neel S. Joshi, Green Chemistry, 2018

The rare earth elements (REEs) play critical roles in modern consumer electronics and clean technologies, but unpredictable supply and environmentally unsustainable extraction practices have spurred efforts to develop green methods of recovering the metals from waste streams. In this regard, we ...

Highly strained [6]cycloparaphenylene: crystallization of an unsolvated polymorph and the first mono- and dianions

03-Jul-2018 | Sarah N. Spisak; Zheng Wei; Evan Darzi; Ramesh Jasti; Marina A. Petrukhina, Chemical Communication, 2018

An X-ray diffraction study of [6]cycloparaphenylene (1), crystallized under solvent-free conditions, revealed a unique solid state structure with tight packing of individual molecules that minimizes empty internal space. The controlled chemical reduction of this highly strained nanohoop with ...

Golden ultrafast melting

29-Jun-2018 | Caroline Ash; Brent Grocholski, Science , 2018

Condensed Matter Understanding fast melting of metals is important for applications such as welding and micromachining. However, fast melting leaves simulation as the only option for probing the process. Mo et al. performed ultrafast electron diffraction experiments on laser-pulsed gold films. ...

Homogeneous Catalysed Hydrogenation of HMF

26-Jun-2018 | Alban Cadu; Kohei Sekine; Jaroslaw Mormul; Dominik M. Ohlmann; Thomas Schaub; Stephen Hashmi, Green Chemistry, 2018

In this report, hydroxymethylfurfural (HMF) is used as a bio-based feedstock for homogeneous metal-catalysed hydrogenation. Several ligand classes and metals are employed to reduce the aldehyde and aromatic ring of HMF. The previously unknown homogeneous catalysed hydrogenation of HMF to ...

Confining electrodeposition of metals in structured electrolytes [Engineering]

26-Jun-2018 | Snehashis Choudhury; Duylinh Vu; Alexander Warren; Mukul D. Tikekar; Zhengyuan Tu; Lynden A. Archer, Proceedings of the National Academy of Sciences current issue, 2018

Electrochemical cells based on lithium and sodium metal anodes are considered among the most versatile platforms for high-energy electrical energy storage. Unfortunately, unstable dendritic metal deposition at currents below the diffusion limit lead to premature cell failure by internal short ...
