Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Direct numerical simulation of forced flow dielectric EHD within charge injection atomizers [PDF]
A charge injection atomizer functions by introducing electric charge discharged from a high voltage electrode into a dielectric liquid, which subsequently atomizes the ejected liquid jet.

Fractional lattice charge transport
AbstractWe consider the dynamics of noninteracting quantum particles on a square lattice in the presence of a magnetic flux α and a dc electric field E oriented along the lattice diagonal. In general, the adiabatic dynamics will be characterized by Bloch oscillations in the electrical field direction and dispersive ballistic transport in the ...

Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Electric charge generation and transport in turbulent wall bounded flows [PDF]
Flow electrification during the transport of dielectric liquids constitutes a major safety hazard. This is particularly the case in petrochemical and process industries, in which several accidents have occurred in the past due to the dielectric ...

Charge Transport in Pentacene–Graphene Nanojunctions [PDF]
We investigate charge transport in pentacene-graphene nanojunctions employing density functional theory (DFT) electronic structure calculations and the Landauer transport formalism. The results show that the unique electronic properties of graphene strongly influence the transport in the nanojunctions.

Reconstructing enzyme evolution by protein engineering
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The charge transport process at poly(orthoaminophenol) film electrodes [PDF]
Poly(o-aminophenol) (POAP) films were deactivated and then reactivated, and dependences of the different charge-transport and charge-transfer parameters on the degree of deactivation (θc ) were obtained by employing Electrochemical Impedance Spectroscopy.

Low bias charge transport in DNA
The low-bias current–voltage technique was utilized to study charge transport in single-stranded DNA (ssDNA), assessing the method’s effectiveness for future studies aimed at estimating the degree of mutation or DNA damage.
