High-performance subambient radiative cooling enabled by optically selective and thermally insulating polyethylene aerogel

open access: yesScience Advances, 2019
Solar reflecting and thermally insulating polyethylene aerogels enable passive radiative cooling to subambient temperatures. Recent progress in passive radiative cooling technologies has substantially improved cooling performance under direct sunlight ...

Polyethylene Glycol Camouflaged Earthworm Hemoglobin. [PDF]

open access: yes, 2017
Nearly 21 million components of blood and whole blood and transfused annually in the United States, while on average only 13.6 million units of blood are donated. As the demand for Red Blood Cells (RBCs) continues to increase due to the aging population,

Biodegradability of polyethylene by bacteria and fungi from Dandora dumpsite Nairobi-Kenya

open access: yesPLoS ONE, 2018
This study aimed at isolating and identifying bacteria and fungi with the capacity to degrade low density polyethylene (LDPE). The level of biodegradation of LDPE sheets with bacterial and fungal inoculums from different sampling points of Dandora ...

Revealing protein structures: crystallization of protein‐ligand complexes – co‐crystallization and crystal soaking

open access: yesFEBS Open Bio, EarlyView.
Co‐crystallization crystallizes a protein with its ligand, resulting in protein–ligand complex crystals. In contrast, soaking introduces a ligand into preformed protein crystals, allowing it to bind. Both methods produce crystals for X‐ray diffraction, which generates diffraction patterns that are analyzed to determine the three‐dimensional structure ...

A novel method for interfacial energy gap determination

open access: yesScientific Reports
A precise quantification of energy gap for a molecular semiconductor is crucial. However, there has always been a lack of a suitable method which results in an inaccurate measurement.

Raman analysis of polyethylene glycols and polyethylene oxides [PDF]

open access: yesJournal of Physics: Conference Series, 2018
We present Raman study of commercial liquids and powders of polyethylene glycols and polyethylene oxides with the average molecular weight from 400 Da to 10000 kDa. The most significant spectral changes were observed for the range of the molecular weights, where the liquid/semisolid transition has occurred.

ExtraPEG: A Polyethylene Glycol-Based Method for Enrichment of Extracellular Vesicles

open access: yesScientific Reports, 2016
Initially thought to be a means for cells to eliminate waste, secreted extracellular vesicles, known as exosomes, are now understood to mediate numerous healthy and pathological processes. Though abundant in biological fluids, purifying exosomes has been

Protein crystallization and structure determination at room temperature in the CrystalChip

open access: yesFEBS Open Bio, EarlyView.
This protocol describes the implementation of a simple and user‐friendly microfluidic device called CrystalChip that allows the production of crystals by the counter‐diffusion method and their in situ analysis by serial crystallography. As an illustration, it is applied to determine the 3D structure of three proteins from data collected at room ...
