Negative capacitance (NC), already observed in conducting polymer-based nanocomposites, was recently reported and evidenced at low frequencies (<10 kHz) non-conducting nanocomposites containing conductive particles. In this contribution, we demonstrate that it is possible to produce economic high-density polyethylene (HDPE) exhibiting an NC effect via a convenient environmentally friendly ex...

High-density polyethylene (HDPE) is widely used for above-ground storage tanks (ASTs). However, there are currently no guidelines the non-destructive testing (NDT) and evaluation (NDE) of HDPE ASTs. Moreover, feasibility, limitations, challenges using NDT techniques field inspection ASTs have not been well established. This study both infrared thermography (IRT) ultrasonic (UT) Highlighting imp...

Combining photolithography and hot embossing offers the capability of cost-efficient and high-fidelity fabrication of polymer microfluidic devices, however, poor chemical resistance in nonpolar organic solvents and high gas permeability of the currently used polymers narrow the range of applications of the microfluidic devices. With the aim of specific chemical or biological applications, we re...

The present study investigates the effects of oxalic acid and 1-methylcyclopropane (1-MCP) treatments in combination with low-density polyethylene (LDPE) high-density (HDPE) on post-harvest storage litchi fruits. physicochemical properties, bioactive compounds, antioxidant activities, dismutase enzyme activity (SOD) treated untreated fruits were examined during 30 days at 4 ℃. most effective wa...
