An improved method for detection of “hot spots” in microelectronic devices

open access: yesТехнологія та конструювання в електронній апаратурі, 2008
A new method of liquid‑crystal thermography for detecting “hot spots” in microelectronic device crystals has been developed. The method is based on the visual display of a “hot spot” by the local cholesteric phase within the transparent smectic phase of ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced 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.

Storage of localized structure matrixes in nematic liquid crystals

open access: yes, 2005
We show experimentally that large matrixes of localized structures can be stored as elementary pixels in a nematic liquid crystal cell. Based on optical feedback with phase modulated input beam, our system allows to store, erase and actualize in parallel

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)

open access: yesAdvanced 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

Band Alignment in In‐Oxo Metal Porphyrin SURMOF Heterojunctions

open access: yesAdvanced Functional Materials, EarlyView.
Porphyrin core metalation in indium‑oxo SURMOFs enables systematic tuning of band edge positions without altering the crystal structure. First‑principles calculations reveal type‑I and type‑II heterostructures as well as multi‑junction energy cascades, establishing a modular strategy for exciton funneling and charge separation in optoelectronic ...

Research of Reliability Enhancement Test for High-speedRailway’s Liquid Crystal Display

open access: yes机车电传动, 2013
Because life damage of the liquid crystal display caused by normal test couldn’t be quantified, and the test cycle was relativelylong, test parameters which equaled to the real life damage were derived by strengthening the test model, and two kinds of ...
