An Innovative Water Splitting Process for a Sustainable In Situ Hydrogen Generation–Reduction of Nitrobenzenes Catalyzed by a New Bimetallic Nanocatalyst [PDF]

open access: yes
In this research, bimetallic CdNi nanoparticles encapsulated in a magnetic spent coffee ground (Fe3O4@COFF/CdNi) was synthesized as a new nanocatalyst. The structural and chemical characteristics of Fe3O4@COFF/CdNi were comprehensively investigated using

Risk Assessment Models for Heated Tobacco Products

open access: yesRisk Analysis, Volume 46, Issue 8, August 2026.
ABSTRACT Heated tobacco products (HTPs) are marketed as alternatives to conventional cigarettes with a potential reduced risk profile. Yet, their actual impact on cancer and noncancer disease risk remains uncertain and requires rigorous quantitative assessment.

Safety and efficacy of a feed additive consisting of nicarbazin (NICACOX®) for chickens for fattening and chickens reared for laying (Huvepharma N.V.)

open access: yesEFSA Journal, Volume 24, Issue 8, August 2026.
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a feed additive consisting of nicarbazin (NICACOX®) as a coccidiostat for chickens for fattening and chickens reared for laying.

Toward Chromoselective Transformations in Biological Systems: Perspectives and Challenges

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 31, 27 July 2026.
Controlling biological systems with small‐molecule chromophores has evolved into a powerful strategy and is applied from chemical biology to medicine. However, the complexity of in vivo systems cannot be matched by a single wavelength of light. Developing methods to combine and individually control multiple chromophores is crucial.

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, Volume 32, Issue 28, 25 July 2026.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Light absorption studies: part I. The ultraviolet absorption spectra of some nitrobenzenes. Part II. The ultraviolet absorption spectra of some benzaldehydes [PDF]

open access: yes, 1958
Part 1. The electronic spectra of nitrobenzenes are discussed in terms of previously proposed hypotheses relating electronic interactions and ultraviolet absorption data. A previously suggested order of mesomeric interaction of the halogens is confirmed,

Headspace liquid phase microextraction for the determination of nitrobenzenes in soil Headspace liquid phase microextraction for the determination of nitrobenzenes in soil Headspace liquid phase microextraction for the determination of nitrobenzenes in [PDF]

open access: yes, 2014
本研究開發以添加丙酮輔助頂空液相微萃取技術結合氣相層析法分析 環境土壤中的硝基苯類污染物,存於土壤基質的硝基苯類藉由水浴加熱, 使其蒸氣壓迅速上升,汽化至頂空氣相中為中空纖維含有的萃取溶劑所萃 取,但由於污染物為半揮發性,沸點介於232.7~269.8℃,加熱尚未使污染 物充分汽化,萃取溶劑即面臨完全揮發的危機,所以本實驗於土壤中添加 少量丙酮,以丙酮蒸氣來保護萃取溶劑,可使萃取時間長達30分鐘而溶 劑尚未揮發,大大提升了方法的偵測極限,待樣品萃取後,將萃取溶劑注 入於氣相層析儀 ...
