Investigation in the Use of Infrared Absorption Spectrophotometry

, 1958
Three rather unrelated projects in infrared spectrophotometry were carried out by the writer. First, some effort was expended in trying to find cell windows which were suitably transparent to infrared radiation and yet water insoluable.

Isolation of Diosgenin from Ethanol Extract of Gadung Tuber (Dioscorea hispida Dennst.) and Identification with The UV-Visible Spectrophotometry and Fourier Transform Infrared

, 2023
Background: Gadung tuber (Dioscorea hispida Dennst.) is widely spread in Indonesia, but has not been fully studied. Gadung tubers have various chemical compounds, one of which is diosgenin. Diosgenin belongs to the steroid saponin class which can be used

Composite materials based on dual network cross‐linking for flexible sensors

FlexMat, EarlyView.
Utilizing hydrogen bond lithium bond dual network structure to effectively enhance the rapid self‐healing properties of flexible ionic materials. Abstract The further development of flexible ionic materials is limited by the evaporation or leakage of their internal liquid state. This article presents a composite flexible ionic material with no internal

Investigation of in vivo measurement of cerebral cytochrome-c-oxidase redox changes using near-infrared spectroscopy in patients with orthostatic hypotension

, 2007
We have previously used a continuous four wavelength near infrared spectrometer to measure changes in the cerebral concentrations of oxy- (Δ[HbO2] and deoxy- haemoglobin (Δ[HHb]) during head-up tilt in patients with primary autonomic failure.

Black phosphorus‐based photothermal disruption of cancer‐associated fibroblast barriers and tumor‐associated macrophage targeting to enhance anti‐PD‐L1 immunotherapy in triple‐negative breast cancer

Interdisciplinary Medicine, EarlyView.
MBB modulates the TNBC tumor microenvironment by targeting TAM/CXCL1 and facilitates anti‐PD‐L1 therapy by disrupting CAF barriers via its photothermal effect. This combined strategy subsequently enhances the efficacy of PD‐L1 mAb and suppresses TNBC progression, metastasis, and recurrence.

Transmission Raman Spectroscopy (TRS) for Accurate Authentication of API in Coated Hydroxychloroquine (HCQ) Tablets

Journal of Raman Spectroscopy, EarlyView.
We report the development and use of a transmission Raman spectroscopy (TRS) system for a more accurate but nonintrusive way of authentication of API in coated HCQ tablets which otherwise is not possible using the backscattered (BS) configuration of Raman spectroscopy. The coating interference is found to be almost zero in case of the TRS and a greater
