Effect of surface pretreatments on the deposition of polycrystalline diamond on silicon nitride substrates using hot filament chemical vapor deposition method [PDF]
, 2009 The deposition of diamond films on a silicon nitride (Si3N4) substrate is an attractive technique for industrial applications because of the excellent properties of diamond. Diamond possesses remarkable physical and mechanical properties such as chemical

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

3D Imaging of Gems and Minerals by Multiphoton Microscopy
, 2018 Many optical approaches have been used to examine the composition and structure of gemstones, both recently and throughout history. The nonlinear optical behavior of different gemstones has not been investigated, and the higher order terms to the ...

Integrated Raman- and angular-scattering microscopy [PDF]
Optics Letters, 2008 A microscopy system has been constructed that is capable of simultaneously acquiring both traditional Raman spectra as well as angle-resolved elastic-scattering patterns using a single focused laser spot less than 10 mum wide. The elastic-scattering signal was analyzed by generalized Lorenz-Mie theory, representing what we believe to be the first ...

Advanced Functional Materials, EarlyView.Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Nickel mediated few-layer graphene growth on glass substrates by pulsed laser deposition
Results in Physics, 2019 This article shows the efficacy of transition metal (Ni) as a top layer on glass in the formation of graphene domain. Graphene films were grown on glass substrates from highly ordered pyrolytic graphite by pulsed laser deposition (PLD), with the help of ...

Water-Gated Charge Doping of Graphene Induced by Mica Substrates
, 2012 We report on the existence of water-gated charge doping of graphene deposited on atomically flat mica substrates. Molecular films of water in units of ~0.4 nm-thick bilayers were found to be present in regions of the interface of graphene/mica hetero ...

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)
Advanced Functional Materials, EarlyView.Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by
