Green chemistry preparation of MgO grit like nanostructures: efficient catalyst for the synthesis of 4H-pyrans and α,α′-bis(substituted-benzylidene) cycloalkanone derivatives

Green Processing and Synthesis, 2016
A grit like nanostructure of MgO was prepared in a medium of mulberry leaves extract and characterized on the basis of field emission scanning electronic microscopy (FE-SEM), X-ray diffraction (XRD), and energy dispersive X-ray (EDX) analysis.

STM-induced surface aggregates on metals and oxidized silicon

, 2011
We have observed an aggregation of carbon or carbon derivatives on platinum and natively oxidized silicon surfaces during STM measurements in ultra-high vacuum on solvent-cleaned samples previously structured by e-beam lithography.

In a nanoscience lab [PDF]

, 2011
The production, observation and manipulation of very small objects is a tour de force, but these objects, which could infiltrate anywhere without being seen, may arouse suspicion. To assess the situation at best, we describe the activity of a nanoscience

Revealing the aging process of solid electrolyte interphase on SiOx anode

Nature Communications, 2023
As one of the most promising alternatives to graphite negative electrodes, silicon oxide (SiOx) has been hindered by its fast capacity fading. Solid electrolyte interphase (SEI) aging on silicon SiOx has been recognized as the most critical yet least ...

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling

Advanced Engineering Materials, EarlyView.
Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Carboxylic‐Acid Functionalized Multiwalled Carbon Nanotube‐Alkane‐Based Resistive Temperature Sensor for Cold Chain Applications

Advanced Engineering Materials, EarlyView.
This study presents a reversible temperature sensor with high switching ratio, ∼103. The device is fabricated using PET‐ITO and carbon nanotube dispersions in alkane. Considering its application in cold chain logistics, a proof‐of‐concept with LED is showcased. Thus, a temperature drop below the threshold temperature (crystallization temperature of the
