The largest group of apprentices have started a journey to become production operators for the Savannah River Site’s liquid waste contractor.
“Solid-Liquid” Vitrimers Based on Dynamic Boronic Ester Networks
Solid-liquid Dynamic covalent bond Boronic ester bond Strain-rate dependent High stretchability
2023/12/8
The “solid-liquid” behavior of vitrimers have not been systematically investigated. Herein, a series of “solid-liquid” vitrimers bearing varying contents of dynamic boronic ester bonds were synthesize...
High-efficient esterification of rosin and glycerol catalyzed by novel rare earth Lewis acidic ionic liquid: Reaction development and mechanistic study
Rosin glyceride Rare earth Lewis acidic ionic liquid Esterification DFT Catalysis
2023/12/7
Background: As one of the most important modified products of rosin, rosin glyceride was widely used in many aspects. However, the preparation of rosin glyceride is always unfriendly due to the use of...
Development and evaluation of a hydrogenated rosin (β-acryloxyl ethyl) ester–bonded silica stationary phase for high-performance liquid chromatography separation of paclitaxel from yew bark
Rosin-based stationary phase Paclitaxel Retention mechanism Separation Yew-bark extract
2023/12/5
Paclitaxel (PTX) is a complex diterpenoid anticancer drug whose separation from yew biomass poses a significant challenge. In this study, a new stationary phase comprising hydrogenated rosin (β-acrylo...
Synthesis of flower-like porous MgO microspheres via a gas-liquid interfacial reaction
Interfacial reaction Basic magnesium carbonate Hierarchical porous structure MgO Adsorption
2023/6/21
The flower-like porous MgO was obtained via a interfacial reaction following by further calcination. In the interfacial reaction, flower-like basic magnesium carbonate microspheres (precursor) were pr...

Solid, liquid, or gas? Technique quickly identifies physical state of tissues and tumors（图）
技术快速识别 肿瘤 癌症诊断
2023/6/19
As an organism grows, the feel of it changes too. In the initial stages, an embryo takes on an almost fluid-like state that allows its cells to divide and expand. As it matures, its tissues and organs...
Researchers film human viruses in liquid droplets at near-atomic detail
human viruses AAV genome
2021/8/11
Researchers have used advanced electron microscopy (EM) technology to see how human viruses move in high resolution in a near-native environment. The visualization technique could lead to improved und...
Liquid film transport around Taylor bubble in a microchannel with gas cavities
Microchannel Gas-liquid Taylor flow Gas cavity Liquid film
2023/3/1
In Taylor flow, the low velocity in liquid film around the bubbles limits the mass transfer between the bubble body and liquid phase. To overcome this deficiency, a cross-junction Microchannel with ga...
Researchers from Cornell’s School of Applied and Engineering Physics and Samsung’s Advanced Institute of Technology have created a first-of-its-kind metalens – a metamaterial lens – that can be focuse...
Influence of Eurotium cristatum and Aspergillus niger individual and collaborative inoculation on volatile profile in liquid-state fermentation of instant dark teas
Instant dark tea Eurotium cristatum Aspergillus niger Liquid-state fermentation Volatile components Sensory analysis
2023/4/20
The three instant dark teas were produced from instant green tea (IGT) by liquid-state fermentations using the microorganisms Eurotium cristatum (EFT), Aspergillus niger (AFT), and sequential inoculat...
