MORPHOLOGICAL CHARACTERS OF CHILLI PEPPER (Capsicum frutescens L.) AS INFLUENCED BY SODIUM AZIDE AT GENERATIVE STAGE OF M1 GENERATION

open access: yesJurnal Biologi Udayana, 2013
Chili pepper (Capsicum frutescens L.) is one vegetable crop that has high economic value.  There are several problems in cultivation of chili pepper, for examples limited land, bad weather, and pests and diseases, which result in low production.

How Much Information Does the Sodium Doublet Encode? Retrieval Analysis of Non-LTE Sodium Lines at Low and High Spectral Resolutions [PDF]

open access: yes, 2019
Motivated by both ground- and space-based detections of the sodium doublet in the transmission spectra of exoplanetary atmospheres, we revisit the theory and interpretation of sodium lines in non-local thermodynamic equilibrium (NLTE), where collisions are not efficient enough to maintain a Boltzmann distribution for the excited and ground states of ...

One pot ‘click’ reactions: tandem enantioselective biocatalytic epoxide ring opening and [3+2] azide alkyne cycloaddition [PDF]

open access: yes, 2010
Halohydrin dehalogenase (HheC) can perform enantioselective azidolysis of aromatic epoxides to 1,2-azido alcohols which are subsequently ligated to alkynes producing chiral hydroxy triazoles in a one-pot procedure with excellent enantiomeric excess.

Pentagonal Monolayer Crystals of Carbon, Boron Nitride, and Silver Azide [PDF]

open access: yes, 2015
In this study we present a theoretical investigation of structural, electronic and mechanical properties of pentagonal monolayers of carbon (p-graphene), boron nitride (p-B$_{2}$N$_{4}$ and p-B$_{4}$N$_{2}$) and silver azide (p-AgN$_{3}$) by performing state-of-the-art first principles calculations.
