The atomic layer deposition of gallium and indium oxide was investigated on mesoporous silica powder and compared to the related aluminum oxide process. The respective oxide (GaO, InO) was deposited using sequential dosing of trimethylgallium or trimethylindium and water at 150 °C. In-situ thermogravimetry provided direct insight into the growth rates and deposition behavior.

- Chronic lithium treatment for bipolar disorder primarily impacts kidney health, leading to conditions like nephrogenic diabetes insipidus (NDI) and chronic kidney disease (CKD), with age, dosage, and treatment duration as key risk factors.
- A study with 29 different inbred strains of female mice showed significant increases in urine production and kidney damage markers associated with lithium treatment, affecting 21 strains' urine concentration abilities.
- Genetic differences among the mouse strains significantly influenced their response to lithium, with urinary β2-microglobulin levels emerging as a potential biomarker for assessing lithium-induced chronic kidney damage.
Atomic layer deposition (ALD) is an industrially applied technique for thin film deposition. The vast majority of processes target flat substrates rather than powders. For ALD on powders, new processes are needed, as different reaction conditions are required.
View Article and Find Full Text PDFA cobalt(i) complex is shown to be capable of both electrocatalytic reduction and hydrogenation of CO2 to formate. Several proposed intermediates are characterized and thus form the basis for a proposed mechanism that allows for the dual reactivity: reduction of CO2via H2 addition, and H+/e- equivalents. The work makes use of a novel tris(phosphino) ligand.

However, it has been suggested that CZT has lower specificity, which might lead to more downstream radiological procedures, particularly among obese individuals.
Methods And Results: We evaluated 244 patients with suspected CHD who underwent CZT-SPECT and matched 1:1 according to sex, age, and body mass index (BMI) with those undergoing MPI study with the Anger gamma-camera (Anger-SPECT).
