An Experimental Study on the Heat and Mass Transfer of Liquid Nitrogen in a Loose Medium
Energies, 2019 Liquid nitrogen is a vital medium during the extinguishing and chilldown process of coal spontaneous combustion in coal mine goafs. In this paper, the heat and mass transfer of liquid nitrogen in a loose medium was investigated.

Microscopy Today, 1996 Abstract Recent Internet postings on the Microscopy listserver indicate paradoxical views on the personal protective equipment (PPE) necessary to handle liquid nitrogen (LN2) safely. Those views range from full protective gear to, somewhat facetiously, complete nudity. The crux of the paradox is that both extremes have points of validity.

The influence of the reactor pressure on the hydrodynamics in a cocurrent gas-liquid trickle-bed reactor [PDF]
, 1990 The influence of the reactor pressure on the liquid hold-up in the trickle-flow regime and on the transition between trickle-flow and pulse-flow has been investigated in a trickle-flow column operating up to 6.0 MPa with water, and nitrogen or helium as ...

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Zhongguo youzhi, 2022 采用高效液氮加注技术对葵花籽油进行灌装，并与气氮加注、气液氮混合加注技术进行对比，研究其对葵花籽油品质和产品包装的影响。结果表明：3种充氮方式样品的酸值和过氧化值变化趋势基本一致；液氮加注样品常温储藏5个月后酸值（KOH）和过氧化值分别为0.07 mg/g和1.45 mmol/kg，与常温储藏相比，液氮加注样品45 ℃储藏5个月后酸值无差别，过氧化值稍有降低，为130 mmol/kg；液氮加注和气液氮混合加注样品初始及储藏过程中的过氧化值比气氮加注样品的稍高；常温下3种充氮方式样品的初始残氧值相差不大，
