Research on Production of 15N Isotope with N2 by Gas Diffusion Method

open access: yesYuanzineng kexue jishu
There are two natural stable isotopes of nitrogen, 14N and 15N, with isotopic abundances of 99.636% and 0.364%. 15N is widely used in research and analysis in atmospheric tracing, agricultural and forestry research, and origin tracing.

A Simple Method for the Determination of Resistance to Gas Diffusion in Plant Organs [PDF]

open access: yesPlant Physiology, 1982
A simple method was developed for the determination of resistance coefficients for ethylene diffusion in plant tissues based on the kinetic analysis of the efflux of preloaded ethane gas. Efflux curves were analyzed to obtain first-order rate constants and resistance coefficients. Resistance coefficients determined by the ethane efflux and steady-state

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

A method for measuring surface diffusion coefficient of coal-adsorbed gas using a differential pressure permeation method

open access: yesMeitan xuebao
The surface diffusion behavior of coal-adsorbed gas is difficult to measure and quantitatively characterize, which has always been a problem or difficulty in the study of the migration law of coalbed methane (coal mine gas).

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

A Gas Source Localization Algorithm Based on Particle Filter in Wireless Sensor Network

open access: yesInternational Journal of Distributed Sensor Networks, 2015
Gas source localization (GSL) is a critical component in wireless sensor network (WSN) which can be used to estimate the position of gas leaks through the gas concentration measured by the monitoring nodes.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

open access: yesAdvanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
