Cu-Electrocatalytic Diazidation of Alkenes at ppm Catalyst Loading.
Journal of the American Chemical Society, 2022The 1,2-diamine motif is prevalent in natural products, small-molecule pharmaceuticals, and catalysts for asymmetric synthesis. Transition metal catalyzed alkene diazidation has evolved to be an attractive strategy to access vicinal primary diamines but ...

ACS Applied Materials and Interfaces, 2021
A novel chemiresistive-type sensor for detecting sub-ppm NO2 has been fabricated using AuPt bimetal-decorated SnSe2 microflowers, which was synthesized by the hydrothermal treatment followed by in situ chemical reduction of the bimetal precursors on the ...

PSS-PANI/PVDF composite based flexible NH3 sensors with sub-ppm detection at room temperature
, 2021Improved ammonia (NH3) sensor is proposed based on polyaniline (PANI) with poly(styrene sulfonic acid) (PSS) as an additive, which was produced by in-suit polymerization of aniline on flexible porous polyvinylidene-fluoride (PVDF) membranes and then ...

Tuning Dispersity by Photo-Induced ATRP: Monomodal Distributions with ppm Copper Concentration.
Angewandte Chemie, 2019Dispersity significantly affects the properties of polymeric materials. However, current methods that control the polymer dispersity are limited to bimodal molecular weight distributions, adulterated polymer chains or low end-group fidelity and rely on ...

Developing strategies to improve agility in the project procurement management (PPM) process
Business Process Management Journal, 2019Purpose The ability of an organization to observe varying demands and efficiently meet them can be described as agility. Project procurement management (PPM) in the past was stable as things did not change very often and were very predictable.

A 6 $\mu$ W ±50 ppm/°C ±1500 ppm/V 1.5 MHz $RC$ Oscillator Using Self-Regulation
IEEE Trans. Circuits Syst. II Express Briefs, 2019A low power RC relaxation oscillator with very low voltage and temperature sensitivities is presented. Supply sensitivity is reduced by using a self-regulation loop that biases the oscillator near its zero-voltage coefficient point. Fabricated in a 65-nm
