Changing the font of the title and abstract of my article

Question

I am trying to use two different fonts in my article. I used the 'sectsty' package to change the font of all the section titles. I now want to change the font of the title of my article to the font that I have used for the section headings.

I also want to change the font used for the title and text of the abstract.

How do I go about doing this?

I want to use the ULG Letter Gothic font. I have installed the font and include it in my article by using

\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{ulgothic}

Edit: I have a sample document attached

\documentclass[twocolumn]{article}

\usepackage[linesnumbered,lined,boxed,commentsnumbered]{algorithm2e}
\usepackage{amsmath}
\usepackage{physics}
\usepackage{indentfirst}
\usepackage{graphicx}


\usepackage{geometry}
 \geometry{
 a4paper,
 left=25mm,
 right=25mm,
 top=30mm,
 bottom=40mm,
 }

\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{ulgothic}

\usepackage{sectsty}
\allsectionsfont{\ttfamily}


\usepackage[sfdefault,light,condensed]{roboto}  


\usepackage{flushend}
\usepackage{abstract}


\usepackage[english]{babel}
\usepackage{blindtext}

\begin{document}

\title{Letter Gothic and Roboto}
\author{Julius\\ Department of Physics\\ BITS-Pilani Hyderabad}
\date{}

\twocolumn[
\maketitle              
\begin{onecolabstract}
\blindtext
\end{onecolabstract}
]

\section{Introduction}
\Blindtext
\section{Discussion}
\Blindtext
\Blindtext
\section{Conclusion}
\Blindtext
\end{document}

Answer 1

I had the same problem. Here is how I did for the title:

\let\oldabstractname\abstractname
\renewcommand*\abstractname{{\emph{\oldabstractname}}}

In this case I am simply using \emph but you can replace it with your own style.

Note that this solution does not remove previous style. If you need it consider using \normalfont or replacing \oldabstractname with the actual abstract title.

For the abstract body style, I have changed it inside the abstract environment.
