Intermetallic RNiSi (R = Ca, La, and Y) Catalysts with Electron-Rich Ni Sites for Continuous Flow Selective Hydrogenation of Maleic Anhydride.

The industrial advancement of downstream products resulting from the directed hydrogenation of maleic anhydride is hindered by the limitations related to the activity and stability of catalysts. The development of nonprecious metal intermetallic compounds, in which active sites are adjustable in the local structures and electronic properties embedded within a distinct framework, holds immense potential in enhancing catalytic efficacy and stability. Herein, we report that nickel-based silicides catalysts, RNiSi (R = Ca, La, and Y), afford high efficiency in the selective hydrogenation of maleic anhydride.

Clinical reliability of pedicled perforator flaps in the management of adult limb and trunk soft tissue sarcomas: Experience of two French expert centres.

Introduction: Limb-sparing surgery combined with radiation has become the standard treatment for soft tissue sarcomas. Despite the many advantages of reconstruction procedures, such as muscle-sparing flap and local reconstruction, the use of pedicled perforator flaps remains non-consensual due to doubts about their reliability when associated with radiotherapy. This study evaluated their surgical reliability in reconstructive surgery for limb and trunk soft tissue sarcomas, in terms of healing time, wound disorders, and postoperative complications, regardless of radiation timing.

Radiation-induced bullous pemphigoid after surgery for soft tissue sarcoma: About a rare case.

Introduction: Radiation therapy may cause a range of side effects of the skin within the irradiated area. Not of all the reactive effects of the skin induced by radiation therapy have to be related to some forms of radiodermatitis, and when non-standard clinical presentations overcome, it may be necessary to undertake appropriate diagnostic tools to not be in trap of wrong diagnosis.

Clinical Case Description: A 76 years-old man undertook resection surgery after a neoadjuvant radiation therapy for a soft tissue sarcoma of his groin region.

Innovative adaptation of the "spare tissues concept" applied for olecranon coverage of a severe burn patient: A case report.

Background: The management of bone exposure in patients with extensive burns could be a challenge due to the lack of healthy tissue. In such cases, it could be interesting to use any still healthy tissue initially destined for amputation and use it to cover up another site. We present the case of a sever burn patient for whom we used the only healthy palmar hand skin to cover an olecranon exposure.

Catalytic wet air oxidation of high BPA concentration over iron-based catalyst supported on orthophosphate.

The catalytic performance of Fe supported on nickel phosphate (NiP) was evaluated for the removal of bisphenol A (BPA) by catalytic wet air oxidation (CWAO) at 140 °C and 25 bar of pure oxygen pressure. The prepared NiP and Fe/NiP materials were fully characterized by XRD, N-physisorption, H-TPR, TEM, and ICP analysis. Iron (Fe/NiP) impregnation of NiP support enhanced the BPA removal efficiency from 37.
