Ni-Ru bimetallic porous carbon sphere(Ni-Ru@PCS) catalysts were synthesized via formaldehyde-assisted, metal-coordinated crosslinking sol-gel chemistry, in which biomass-derived tannic acid and F127 surfactant were used as carbon precursor and soft template, respectively, and Ni2+and Ru3+were used as cross-linkers. In the developed method, Ni-Ru particles became uniformly dispersed in the carbon skeleton due to strong coordination bonds between metal ions(Ni2+and Ru^(3+)) and tannic acid molecules and bimetal interactions. The as-synthesized Ni-Ru10:1@PCS catalyst with a loading Ni:Ru mole ratio of 10:1 was applied for the selective hydrogenation of glucose to sorbitol, and provided 99% glucose conversion with a sorbitol selectivity of 100% at 140℃ in 150 min reaction time and exhibited good stability and recyclability in which sorbitol yield remained at 98% after 4 cycles with little or no metal agglomeration. The catalyst was applied to glucose solutions as high as 20 wt% with 97% sorbitol yields being obtained at 140℃ in 20 h. The developed bimetallic porous carbon sphere catalysts take advantage of sustainably-derived materials in their structure and are applicable to related biomass conversion reactions.

The most common spinal pathology seen in the obstetric population is lumbar disc herniation. There is currently no literature documenting the safety of performing an epidural blood patch on obstetric patients with underlying spinal pathology. We present a case of a patient with known severe lumbar spinal stenosis with compressive radiculopathy who received a successful epidural blood patch without worsening her underlying neurologic symptoms. Epidural blood patches can be safely performed in this patient population. However, the anesthesiologist should be aware of the risk of potentially worsening preexisting neurological deficits. Thus, we advise caution prior to placing an epidural blood patch on these patients. The risks and benefits of the procedure should be carefully weighed and considered. It is important to have a thorough discussion with the patient regarding the risks of an epidural blood patch prior to performing the procedure.
