• Chemists create the brightest-ever fluorescent materials
  

  By formulating positively charged fluorescent dyes into a new class of materials called small-molecule ionic isolation lattices (SMILES), a compound's brilliant glow can be seamlessly transferred to a solid, crystalline state, researchers report August 6 in the journal Chem. The advance overcomes a more

• Striped Glow Sticks
  

  It may be possible to reach new levels of miniaturization, speed, and data processing with optical quantum computers, which use light to carry information. For this, we need materials that can absorb and transmit photons. In the journal Angewandte Chemie, Chinese scientists have introduced a new str more

• A Close Look at Lithium Batteries
  

  Batteries with metallic lithium anodes offer enhanced efficiency compared to conventional lithium-ion batteries because of their higher capacity. However, safety concerns and a short lifespan stand in the way. To better analyze the causes of malfunctions and premature failure of such batteries, rese more

• Characterizing Biotherapeutics with HPLC
  

  As demonstrated here, there are a broad range of HPLC applications used in development, production, validation and release of protein therapeutics for human use. Some of the applications mentioned above are mandatory when submitting a new biopharmace more

• ORAC Assay Performed on the POLARstar Omega and PHERAstar FS microplate reader
  

  In all oxygen consuming cells, metabolism and oxidative stress generate several intermediates and byproducts that are collectively known as reactive oxygen species (ROS). ROS are necessary intermediates in the human body, but they are also involved i more

• Process optimization made easy: design of experiments with multi-bioreactor system BIOSTAT® Qplus
  

  Design of experiments (DoE) is one of the most important techniques for systematic planning, execution and statistical evaluation of experiments. Although a DoE investigation is executable in one bioreactor, multi-bioreactor systems designed for pa more

The Chemistry of Turmeric

If you’ve ever made a curry, you’ve likely used turmeric – you may even have some in your kitchen right now. It’s probably not the first thing that comes to mind when you think about doing chemistry, but there are actually some pretty neat chemistry tricks you can do with it! In this post, we take a more

• One-pot synthesis of highly fluorescent Fe2+-doped carbon dots for dual-emissive nanohybrid to detection of zinc ions and histidine

  Metal ions-doping is paid a little attention comparing with the nonmetallic-element doping to improve the fluorescence intensity of carbon dots (CDs). Herein, Fe2+-doped CDs was facilely synthesized at 80 °C instead of hydrothermal method for the first time. Fe2+ was confirmed to be the only definit more

• A benzimidazole-based highly selective colorimetric and far-red fluorometric pH sensor for intracellular imaging

  A turn-on fluorescent probe (E)-4-(2-(1H-benzo[d]imidazol-2-yl)vinyl)-N,N-diphenylaniline (BVD) was facilely synthesized via the ethylene bridging of triphenylamine and benzimidazole. The probe exhibited strong emission enhancement in the vis-NIR fluorescence region at 605 nm with pKa 4.14 and linea more

• Impact of kilobar pressures on ultrafast triazene and thiacyanine photodynamics

  Very short fluorescence lifetimes evidence ultrafast deactivation of photoexcited molecules. To unveil the underlying mechanism for two compounds exhibiting (sub)picosecond emission dynamics, we combine femtosecond fluorescence upconversion with high-pressure liquid-phase spectroscopy. For the triaz more
