Carbon dioxide laser-assisted posterior cordotomy (LAPC) is an effective technique for the treatment of Bilateral Vocal Cord Paralysis (BVCP). For our case series we included 34 patients of BVCP from combined military hospitals of Rawalpindi, Lahore, Malir and Quetta and compiled the results of carbon dioxide LAPC which they underwent under general anesthesia between December 2009 to January 2017. Assessment of voice quality and breathing difficulty was carried out before and six weeks after the operation and graded according to scales. The complications after surgery were also noted. In the study, there were 10 (29.4%) males and 24 (70.6%) females. The mean age of the sample was 39.1 } 13.2 years. Overall, there was an improvement in breathing and mild worsening of voice quality after LAPC. The common complications after LAPC were dysphagia, revision surgery, and post-operative pain in 11.8%, 17.6%, and 17.6% respectively. The study concluded that carbon dioxide LAPC was associated with an improvement in breathing but resulted in a poor voice quality among patients with BVCP, along with a few side effects.

Catalytic Conversion of Carbon Dioxide to Long Chain Esters via Formate Hydroesterification.

CO2-based hydroesterification is an attractive route to produce value added ester compounds, which could replace CO-based hydroesterification processes if sufficient catalytic technologies are developed. One path to CO2-based hydroesterification is through an organoformate intermediate, which is then used in olefin hydroesterification to generate the desirable esters. This route creates a net CO2-based hydroesterification process using tandem catalytic systems for CO2 hydrogenation to organoformate paired with formate-olefin hydroesterification.

Precise sub-Ångstrom-level porosity engineering, which is appealing in gas separations, has been demonstrated in solid carbon, polymer, and framework materials but rarely achieved in the liquid phase. In this work, a gas molecular sieving effect in the liquid phase at sub-5 Ångstrom scale is created via sophisticated porosity tuning in calixarene-derived porous liquids (PLs). Type II PLs are constructed via supramolecular complexation between the sodium salts of calixarene derivatives and crown ether solvents.

The discovery of the functioning of intra- and extracellular ion compartments and cell membranes' operation opened the possibility of extending Claude Bernard's theory to intracellular ions. In contrast, by underestimating the role of ions, many misconceptions have prevailed. The author points out that maintaining the constancy of carbon dioxide is especially important.

In homogeneous catalysis, uncovering structure-activity relationships remains very rare but invaluable to understand and rationally improve performances. Here, generalizable structure-activity relationships apply to a series of heterodinuclear polymerization catalysts featuring Co(III) and s-block metals M(I/II) (M= Na(I), K(I), Ca(II), Sr(II), Ba(II)). These are shown to apply to polycarbonate production by the ring-opening copolymerizations (ROCOP) of cyclohexene oxide (CHO) and carbon dioxide (CO2), conducted at high (20 bar) and low (1 bar) CO2 pressures, and to polyester production by copolymerization of cyclohexene oxide and phthalic anhydride (PA).

The development of catalytic technologies for sustainable energy conversion is a critical step toward addressing fossil fuel depletion and associated environmental challenges. High-efficiency catalysts are fundamental to advancing these technologies. Recently, field-effect facilitated catalytic processes have emerged as a promising approach in energy and environmental applications, including water splitting, CO reduction, nitrogen reduction, organic electrosynthesis, and biomass recycling.
