Owing to the revolutionary development in the field of terahertz technology numerous advancement has taken place. In order to make a contribution to this field the proposed work focuses on the design and analysis of terahertz microstrip patch antenna that can be suitably deployed for determination of vitamins L-ascorbic acid and Thiamine hydrochloride. Flame Retardant (Fr4) material with thickn...

A competitive CZE method for quality control analysis of multivitamin preparations and veterinary products containing B-group vitamins was developed. Vitamins of interest are thiamine hydrochloride (B(1)), thiamine monophosphate chloride (B(1a)), riboflavine (B(2)), riboflavine-5'monophosphate (B(2a)), nicotinamide (B(3)), d-pantothenic acid calcium salt (B(5)), pyridoxine hydrochloride (B(6)),...

Acupuncture has long been used to treat urticaria in the Asian world. Acute urticaria can be easily and effectively treated with acupuncture. L111 (Quchi), Sp10 (Xuehai), Sp6 (Sanyinjiao), and S36 (Zusanli) are the 4 acupuncture points most commonly prescribed. Chronic urticaria is a challenge for medical therapy.

In the present investigation, solution casting method was used for the preparation of nanocomposite (NC) films. At first, the surface of ZrO2 nanoparticles (NPs) was modified with vitamin B1 (VB1) as a bioactive coupling agent to achieve a better dispersion and compatibility of NPs within the poly(vinyl chloride) (PVC) matrix. The grafting of modifier on the surface of ZrO2 was confirmed by Fou...

Herein we explore facile synthesis of 4-(3H)-Qunazolinone derivatives, achieved by the cyclocondensation of anthranilic acid, aromatic amines and triethyl orthoformate in presence of thiamine hydrochloride (Vitamin B1) as a catalyst, using grinding method. This protocol offers several advantages such as reusability of catalyst, excellent yield, shorter reaction time and economic availability.Qu...
