The photocatalytic activities of g-C3N4can be significantly improved by increasing life time of the photogenerated charges. Here, in this work we introduced TiO2as proper energy platform to accept the photogenerated electrons from g-C3N4during photocatalysis. The nanophotocatalysts formed from the combination of a suitable amount of TiO2nanoparticles and g-C3N4nanosheets showed 8.75 and 4.22% enhancement in photocatalytic activities for CO2reduction and 2-chlorophenol(2-CP) degradation under visible light illumination as compared to bare g-C3N4. Based on the surface photovoltage spectra, photoluminescence spectra and examination of formed hydroxyl radicals, it was confirmed that these enhanced photoactivities were attributed to the much-improved charge separation via the electron transfer from g-C3N4to TiO2. From trapping experiments,it was found that hydroxyl radicals were the major species involved in the photocatalytic degradation of *** study is helpful to synthesize efficient photocatalysts to cope with energy and environmental issues.

OBJECTIVE： To evaluate the antibacterial activity of the combination of different honey brands and methanolic fraction of Herba Ocimi Basilici using agar well diffusion assay. METHODS： The antibacterial activity was deter- mined against thirteen pathogenic bacterial clini- cal isolates including six gram negative （Klebsiella pneumonia, Pseudomonas aeroginosa, Escherichia coli, Salmonella typhi, Salmonella typhimirium, Xanthomonas campestris） and six gram positive strains （Enterococcus faecalis faecalis, Bacillus subti- lis, Staphylococcus aureus, Clostridium perfringens type C, Clostridium perfringens type D, CIostridium chauvoei）. Agar well diffusion method was used while zones of inhibition were measured with verni- er scale. RESULTS： At higher concentration, all the honey brands showed good to significant activity. Thehighest activity was observed for Hamdard brand honey （27.60±0.40） against Enterococcus faecalis. CONCLUSION： These results revealed that combi- nations of plant extracts of Herba Ocimi Basilici with honey can be used for the development of potent and novel antibacterial agents.

In context with a recent announcement by the World Health Organization(WHO)holding an emergency towards an infectious illness indistinguishable from smallpox,monkeypox(mpox)carried a high case fatality(12%)[1,2].The variable distribution of cases during 2022-2023 in non-endemic regions i.e.,Europe(20000),China(1098),US(475),India(75),Japan(31),Pakistan(11)may cause an overwhelming demise with an additional burden on the economy[3].

Matrix-assisted laser desorption/ionization (MALDI) is a preferred and widely used mass spectrometric technique for the analysis of macromolecules. Limited UV-LDI matrices are available for the analysis of biomolecules due to the restricted structural features to serve in the laser desorption/ionization mechanism with a problem of background signals appearing in the low mass region. This paper describes the application of Schiff base derivatives of acylhydrazide and isatin as alternate UV-LDI matrices for the analysis of peptides with significantly low background signals. Thirty one compounds have been successfully employed as matrices for the analysis of low molecular weight (LMW) peptides (α-Cyano-4-hydroxycinnamic acid (HCCA), a preferred choice for peptide analysis.
