To Telescope or Not To Telescope?

open access: yesRobotic Telescopes, Student Research and Education Proceedings, Vol 1, No 1, 2018
With the rapidly growing number of Internet-accessible and Internet-controlled research-grade telescopes becoming available, astronomy educators are rushing to create authentic research-programs for students that leverage these new resources. To date, the most successful programs are those that focus on upper-level science-focused students or highly ...

Active optics in astronomy – modeling of deformable substrates: freeform surfaces for FIREBall and MESSIER

open access: yesJournal of the Mechanical Behavior of Materials, 2018
Active optics techniques on large telescopes and astronomical instrumentations provide high imaging quality. For ground-based astronomy, the co-addition of adaptive optics again increases angular resolution up to providing diffraction-limited imaging at ...

The Metagenomic Telescope

open access: yesPLoS ONE, 2014
Next generation sequencing technologies led to the discovery of numerous new microbe species in diverse environmental samples. Some of the new species contain genes never encountered before. Some of these genes encode proteins with novel functions, and some of these genes encode proteins that perform some well-known function in a novel way.

Probing Diversity of Type II Supernovae with the Chinese Space Station Telescope

open access: yesUniverse, 2023
Type II supernovae (SNe II), which show abundant hydrogen in their spectra, belong to a class of SNe with diverse observed properties. It is commonly accepted that SNe II are produced by core collapse and explosion of massive stars.

Strain‐Release Pentafluorosulfanylation of Carbonyl‐Containing Disubstituted Bicyclobutanes: A Fortuitous Path to SF5‐Containing Oxa[2.1.1]bicyclohexanes

open access: yesAngewandte Chemie, EarlyView.
A regio‐ and diastereoselective method for strain‐release pentafluorosulfanylation of carbonyl‐containing 1,3‐disubstituted [1.1.0]bicyclobutanes (BCBs) was developed that led to several fortuitous discoveries. For instance, the resultant SF5‐cyclobutanes (SF5‐CBs) exhibit close SF5⋯C═X contacts (X = C, N, O) and provide synthetic access to a new class
