Design of a single-chip pH sensor using a conventional 0.6-μm CMOS process [PDF]

, 2004
A pH sensor fabricated on a single chip by an unmodified, commercial 0.6-/spl μm CMOS process is presented. The sensor comprises a circuit for making differential measurements between an ion-sensitive field-effect transistor (ISFET) and a reference ...

Chemical and biochemical sensors based on silicon nanowire field-effect transistor arrays [PDF]

, 2014
Field-effect transistors (FETs) made from semiconducting nanowires have great potential as electronic biochemical sensors if they can be integrated as an array in a CMOS-compatible architecture together with microfluidic channels and interfacing ...

Dual-barrel conductance micropipet as a new approach to the study of ionic crystal dissolution kinetics [PDF]

, 2013
A new approach to the study of ionic crystal dissolution kinetics is described, based on the use of a dual-barrel theta conductance micropipet. The solution in the pipet is undersaturated with respect to the crystal of interest, and when the meniscus at ...

Anoxic Biodegradation of Isosaccharinic Acids at Alkaline pH by Natural Microbial Communities

, 2015
One design concept for the long-term management of the UK’s intermediate level radioactive wastes (ILW) is disposal to a cementitious geological disposal facility (GDF).

Chemical and kinematical evolution in nearby dwarf spheroidal galaxies [PDF]

, 2006
Dwarf spheroidal (dSph) galaxies are the least massive and luminous objects known to exist. These galaxies are often considered as the fossil building blocks of massive systems predicted by some cosmological models.

Temporal viscosity Modulations Driven by a pH Sensitive Polymer Coupled to a pH-Changing Chemical Reaction

, 2017
The Formaldehyde-Sulfite (FS) and the Formaldehyde-Sulfite-Gluconolactone (FSG) systems are examples of complex chemical reactions accompanied by well-controlled variations in pH.

Rigid Schiff Base Complex Supermolecular Aggregates as a High-Performance pH Probe: Study on the Enhancement of the Aggregation-Caused Quenching (ACQ) Effect via the Substitution of Halogen Atoms

, 2022
Optical signals of pH probes mainly driven from the formation or rupture of covalent bonds, whereas the changes in covalent bonds usually require higher chemical driving forces, resulting in limited sensitivity and reversibility of the probes.

A quantum chemical study on the formation of phosphorus mononitride

, 2009
The chemical mechanism of the (1)PN formation was successfully studied by using the CCSD(T)/6-311++G(3df,3pd) level of theory. The (1)NH(3) + (3)PH and (4)P + NH(3) reaction paths are not energetically favorable to form the (1)PN molecule.
