ConspectusChiral organosilicon compounds bearing a Si-stereogenic center have attracted increasing attention in various scientific communities and appear to be a topic of high current relevance in modern organic chemistry, given their versatile utility as chiral building blocks, chiral reagents, chiral auxiliaries, and chiral catalysts. Historically, access to these non-natural Si-stereogenic silanes mainly relies on resolution, whereas their asymmetric synthetic methods dramatically lagged compared to their carbon counterparts. Over the past two decades, transition-metal-catalyzed desymmetrization of prochiral organosilanes has emerged as an effective tool for the synthesis of enantioenriched Si-stereogenic silanes.

Medicaid Spending in Coordination-Only Dual-Eligible Special Needs Plans.

Importance: More than 4 million Medicare beneficiaries have enrolled in dual-eligible Special Needs Plans (D-SNPs), and coordination-only D-SNPs are common. Little is known about the impact of coordination-only D-SNPs on Medicaid-covered services and spending, including long-term services and supports, which are financed primarily by Medicaid.
Objective: To evaluate changes in Medicaid fee-for-service (FFS) spending before and after new enrollment in coordination-only D-SNPs vs new enrollment in non-D-SNP Medicare Advantage (MA) plans among community-living beneficiaries enrolled in both Medicare and North Carolina Medicaid.
Catalytic Hydrogenation of CO by Direct Air Capture to Valuable C1 Products Using Homogenous Catalysts.

Growing atmospheric CO concentrations are a global concern and a primary factor contributing to global warming. Development of integrated CO capture and conversion protocols is necessary to mitigate this alarming challenge. Though CO hydrogenation to produce formic acid and methanol has seen many strides in the past decades, most studies utilize pure CO for this transformation.

Magnesium oxide (MgO) is known for its bioactivity and osteoconductivity when incorporated into biodegradable poly(lactic acid) (PLA), whereas the weak interfacial bonding between MgO microspheres (mMPs) and PLA often leads to suboptimal composite properties with uncontrollable functionality. Conjugation of mMPs with PLA may offer a good way to enhance their compatibility. In this study, we systematically investigated two grafting techniques, solution grafting (Sol) and melt grafting (Mel), to decorate poly (D-lactic acid) (PDLA) on mMPs pre-treated by prioritized hydration to obtain Sol MPs and Mel MPs, in order to optimize the grafting efficiency and improve their controllability in the properties including the crystal structure and surface morphology.
