Quorum sensing (QS) is a bacterial communication process in which cells detect the local environment and collectively activate gene expression. The transcriptional activator (LuxR) for these genes has a specific allosteric ...

Herein, an efficient approach to synthesize various hexahydro-1H-xanthene-1,8-dione or dibenzo xanthene containing bioactive spirooxindole derivatives is reported by using FeCl3 ⋅ 6H2O mediated spiro coupling of 1,3-diketone ...

Biochar is a carbon-rich solid prepared by the thermal treatment of biomass in an oxygen-limiting environment. It can be customized to enhance its structural and electrochemical properties by imparting porosity, increasing ...

Thiophene-based expanded porphyrinoids undergo a transition from a planar conformation to a twisted conformation upon a systematic increase in the number of thiophene units. Octaphyrin, with 40π electrons, displayed ...

We study a one-dimensional sluggish random walk with space dependent transition probabilities between nearest-neighbour lattice sites. Motivated by trap models of slow dynamics, we consider a model in which the trap depth ...

Hydrogen sulfide (H2S) and associated sulfur species known as persulfide or sulfane sulfur are considered among the first responders to oxidative stress. However, tools that reliably generate these species without any ...

The dependence of the ratio between the B-s(0) and B+ hadron production fractions, f(s)/f(u), on the transverse momentum (p(T)) and rapidity of the B mesons is studied using the decay channels B-s(0) -> J/psi phi and B+ ...

A search for the production of pairs of heavy Majorana neutrinos (N-& ell;) from the decays of Z ' bosons is performed using the CMS detector at the LHC. The data were collected in proton-proton collisions at a center-of-mass ...

Chiral coordination cages have emerged as an efficient platform for enantioselective processes via host–guest interactions. Here, we report an enantiomeric pair of tetrahedral cages of formula [(Pd3[PO(N(*CH(CH3)Ph)3])4(C4O4)6] ...
