In this study, new composite materials comprising zeolitic imidazolate framework (ZIF) structures and microchannel glass (MCG) plates were fabricated using the hydrothermal method and their morphological and spectral properties were investigated using XRD, SEM, FTIR, and Raman spectroscopy. XRD studies of powder samples revealed the presence of an additional phase for a ZIF-8 sample, whereas ZIF-67 samples, which were prepared through two different chemical routes, showed no additional phases. A detailed analysis of the FTIR and micro-Raman spectra of the composite samples revealed the formation of stable ZIF structures inside the macropores of the MCG substrate. The hydrophilic nature of the MCG substrate and its interaction with the ZIF structure resulted in the formation of stable ZIF-MCG composites. We believe that these composite materials may find a wide range of important applications in the field of sensors, molecular sieving.

StockMarketWire.com - Finsbury Food said it would resume its dividend as the bakery chain upgraded its outlook on annual profit after reporting strong second-half performance.
Trading in the second half of the financial year had been strong and the company now anticipated that pre-tax profit for the full year will be no less than £15.0m, ahead of current market expectations.
The strong trading had been driven by improving volume performance and the benefits and improved line efficiency including lower waste throughout the group s bakeries. In the light of the expected performance and the current outlook, the board plans on reintroducing the payment of the dividend for the financial year ending 26 June 2021, the company said.
